The operation of the county landfill is performed by the city of Dubuque through a contract with the Agency. The costs involved with the operation of the landfill facility are covered entirely by tipping fees. Historically, tipping fees have increased from $3.50 per ton in 1976 to $11.00 per ton in fiscal 1991. Because of the need for improvements at the landfill to comply with new regulations, the tipping fee will increase to $22.00 per ton in fiscal 1992. There is a relatively recent recycling effort in the Dubuque County area; however, all of the communities in the study area (Table 3-2) continue to use the Dubuque County Landfill as the primary disposal method, with the exception of the city of Bernard whose waste is taken to the Jackson County Landfill. There are eight municipalities in the county that have municipally operated collection systems. All others within the project area and the rural population have private contractors who haul to the landfill. The private contractors either contract with the towns or directly with the homeowners. The collection system is large, and the rural residential population is extensive. There are approximately ten private collectors in Dubuque County; some who are hauling yard waste as well as solid waste. All municipalities have required the elimination of yard wastes from garbage as of July 1, 1990. Yard waste separation is only one example of the need to closely monitor the collection system within the study area to assure cooperation with the DMASWA. The requirement for solid waste management through comprehensive planning was enacted by the Iowa Legislature as part of the Groundwater Protection Act in 1987. The act established a separate branch of the Iowa Department of Natural Resources to lead waste reduction and recycling efforts. Part I of the Comprehensive Plan establishes the hierarchy of solid waste disposal options. • Volume Reduction at the Source o Recycling and Reuse o Combustion with Energy Recovery and/or Refuse Derived Fuel o Combustion for Volume Reduction o Landfilling These items need to be carefully studied and evaluated for all solid waste disposal projects. Renewal of landfill operating permits are tied to the Comprehensive Planning requirements. The Legislative Review in Chapter 2 covers the current requirements in more detail. The implementation of a Comprehensive Plan for solid waste management with- in Dubuque County involves technical considerations as well as many issues relating to administrative structure and the general public. The Dubuque 1.2 BACKGROUND Comprehensive solid waste management planning is a requirement established under the Groundwater Protection Act passed by the Iowa Legislature in 1987. The Dubuque Metropolitan Area Solid Waste Agency (DMASWA) was created through a 23-E Agreement to oversee a county -wide landfill program in 1976. Since that time, all of the cities and towns within Dubuque County have agreed to use the landfill operated by the DMASWA. The participating muni- cipalities are bound by the 28E Agreement until all bonds used to finance the landfill are paid. It is anticipated that the final bond payment will be made some time in 1995. In June 1990, the DMASWA contracted with Brice, Petrides-Donohue to examine the existing solid waste disposal system and develop a system for manage- ment of the entire waste stream incorporating disposal alternatives as required under the Groundwater Protection Act. The existing county -wide landfill operated by the DMASWA consists of approximately 214 acres, of which approximately 115 acres are to be devel- oped as a landfill. The original facilities plan written in 1975 estimated landfill life at 20 years; however, a follow-up report in 1985 estimated remaining landfill capacity at current tonnages at 35 years. Using the figures in the most recent report and assuming the county landfill has adequate cover material, the facility has 30 years capacity at current tonnages. A fill area for demolition materials, which is scheduled to close in 1991, is in operation elsewhere in the county and John Deere operates its own waste disposal at their plant location. If these waste streams are directed to the DMASWA landfill, the remaining useful life will decrease. Nation-wide, solid wastes from residential, commercial and institutional sources are estimated at 160 million tons per year, or 1,300 pounds per person per year. Approximately 85 percent of municipal solid waste is disposed of in sanitary landfills. The Dubuque metro area solid waste study area has a waste generation rate that is generally in line with the national average. The EPA projects that generation rates will increase from the present 3.5 pounds per capita to 6.5 pounds per capita by the year 2000. Even though goals have been established by federal and state agen- cies to reduce dependence on landfilling, if waste generation rates con- tinue to increase, the quantity of materials landfilled may not be reduced. The Dubuque Metropolitan Area Solid Waste Agency oversees the operation of the county landfill. The agency consists of a three -member board of direc- tors, two members of the Dubuque City Council and one member from the Dubuque County Board of Supervisors. The agency's duties include: 1) the economical disposal of all solid waste, 2) to encourage other local government agencies to administer, operate and maintain facilities, 3) provide equipment, machinery, buildings and grounds for the transport 1.1 104 lon 101 ra Metropolitan Area Solid Waste Agency has authority to implement this plan. The intent of a Comprehensive Solid Waste Management Plan is to provide direction in implementing any or all alternatives in landfilling within Dubuque County. The plan has been prepared in light of current factors and conditions; however, it will need to be monitored and updated as waste stream, technology, law and environmental factors change. Public awareness is an essential element in implementing changes in solid waste management practices in Dubuque County. This issue is addressed in a separate chapter on Citizen Participation. Reports/Dubuque/AA6 1.3 LEGISLATIVE REVIEW The Solid Waste Disposal Act was passed by the Iowa Legislature in 1970. This Act required that all solid waste be disposed in a "sanitary disposal project." The Act also established guidelines and permitting procedures to be administered through the then relatively new Iowa Department of Environ- mental Quality (IDEQ) (now the Iowa Department of Natural Resources - IDNR). The compliance date for the Act was established as July 1, 1975. In response to the Solid Waste Disposal Act, most counties and some cities organized solid waste disposal authorities, either through their City Coun- cil, County Board of Supervisors or special purpose commissions or agencies formed under the authority of Section 28-E of the Code of Iowa. These multi -governmental 28-E agencies had authorities defined in their individu- al agreements but were also limited by the state Code. Recently, the Code has enabled the authorities of these multi -governmental agencies to be expanded under Sections 28-F and 28-G. Although there were numerous solid waste disposal technologies available in the early 1970s, there were very few commercially successful. The costs, benefits and risks associated with solid waste disposal at the time made landfilling the technology of choice for most of the facilities in the state. IDNR (then IDEQ) developed administrative rules which dealt with siting and operation of landfills. In general, the facilities developed in response to the Solid Waste Disposal Act are those that are in operation currently. The existing solid waste disposal projects in the study area operate under permits issued by IDNR. Federal legislation, primarily in response to hazardous waste issues, also impacted solid waste disposal. The Resource Conservation and Recovery Act (RCRA) was passed in 1976. This legislation established stringent controls on hazardous wastes with a cradle -to -grave philosophy for treatment, stor- age and disposal facilities. Subtitle D regulations of RCRA were promul- gated and issued for public comment in August, 1988. It is currently anti- cipated that these regulations will go into effect in 1991, and could have significant impacts on existing sanitary landfills. The Subtitle D regulations would expand RCRA authority from hazardous waste facilities to include all solid waste disposal facilities. For many existing facilities, the RCRA regulations will be very far reaching and require significant changes. The Black Hawk County Landfill can be used as an example of the potential effects of Subtitle D regulations. The Black Hawk County facility is an interim status hazardous waste facility and, as such, has been regulated under Subtitle C of RCRA. The facility has currently installed 54 monitoring wells and has also undertaken formal closure of approximately 40 acres of the 140-acre site. To comply with the various RCRA requirements has taken approximately 5 years at a cost of approximately $3 million. Highlights of the RCRA Subtitle D regulations follow: 2.1 Pw PRI RCRA Subtitle D The regulations will affect all landfills that are not closed within 18 months after the regulations are promulgated. EPA esti- mates that compliance with the new Subtitle "D" regulations will cost between $400 million and $3 billion annually. EPA estimates 3,000 of the result of the a significant that over the next several current 6,000 municipal Subtitle "D" regulations. trend toward development new regional landfills. years as many as 2,000 to landfills may close as a There may, therefore, be of transfer stations and The new regulations do not require retrofitting of existing land- fill units with liners or leachate collection systems. However, any facility in operation on the date of rule promulgation would have to install a final cover that meets the risk -based perform- ance standard. The largest impact is likely to be felt by existing facilities that expand laterally into new units. These new units would, in most cases, be required to install liners and leachate collection systems. Key Requirements General 1. The proposed regulations present siting restrictions for new facilities addressing proximity to airports, 100-year flood plains, wetlands, fault areas, seismic impact zones and unstable areas. 2. Under the proposed regulations, the owner or operator of a MSWLF would be required to demonstrate the financial and technical ability to con- duct closure and post -closure care and, if applicable, corrective ac- tion for known releases. This requirement would insure that the owner or operator adequately plan for all of the costs involved. State and federal entities would be excluded from financial assurance require- ments, but local governments would not be excluded. The amount of financial assurance required would be based on written site -specific cost estimates. The cost estimates would include closure, post -closure care and corrective action for known releases. Design 1. The proposed design criteria establish a performance standard that allows states flexibility in determining the allowable risk level and the point of compliance. New and existing units would be required to meet the performance standard, but different options for control mechanisms are given for each. 2.2 2. New units would be required to be designed with liners, leachate col- lection systems and final cover systems as necessary to meet a state - established design goal. Each state can establish its design goal with certain carcinogenic risk levels for the groundwater beneath the land- fill. The states would be allowed flexibility in requiring liners, leachate collections systems and final covers -- within a limited pro- jected risk range of one cancer incidence in 10,000 exposures to one cancer incidence in 10 million exposures. The point of compliance would be at the waste management unit boundary or state -established alternative boundary. The alternative boundary would be no more than 150 meters from the waste management unit boundary and would be re- quired to be on facility -owned land. 3. Developing programs to comply with the federal performance standards will place a heavy burden on state environmental protection agencies. Groundwater Monitoring 1. EPA estimates that at least one in every four of the existing 6,000 municipal landfills is violating current groundwater protection stand- ards. 2. The groundwater monitoring and corrective action requirements proposed by EPA under Subtitle "D" are very similar to those being used for RCRA Subtitle "C" hazardous wastes facilities. The proposed requirements would apply to all new and existing landfill units. 3. Phase 1 monitoring consists of semi-annual sampling of 15 indicator parameters, 9 heavy metals and 46 volatile organic compounds. If a statistically significant increase or decrease occurs over background for two or more indicator parameters or one or more heavy metals or VOCs, Phase 2 monitoring program would be required. 4. Phase 2 monitoring consists of analyzing groundwater for 234 para- meters. The minimum sampling frequency for these parameters is quarterly. If a statistically significant increase above the trigger level occurred for any parameter, the owner would be required to pro- ceed with corrective actions. 5. Corrective action requirements would mandate that owners perform an assessment of corrective measures, select corrective measures, estab- lish a groundwater protection standard and implement a corrective action program. Landfill Gas Monitoring 1. Because methane has been the principal cause of explosions, EPA pro- poses monitoring only for that landfill gas parameter at this time. EPA may require monitoring for other gas constituents in the future if 2.3 1101 information is developed indicating that this is necessary. Operating landfills must monitor for methane gas migration in the soil, in fa- cility structures and at the property boundary. 2. Although the proposed regulations require only methane monitoring, it is expected that the monitoring will indicate the need for implementa- tion of landfill gas controls at many facilities. If excessive methane levels are detected, the owner must take necessary steps to insure protection of human health. A remediation plan would need to be sub- mitted to the state within 14 days of certain limits having been ex- ceeded. 3. EPA proposes methane monitoring at least quarterly. Site -specific conditions may require more frequent monitoring, such as when facili- ties are near residential areas. 4. EPA recommends that continuous monitoring devices be used in facility structures at the landfill. Operations 1. Procedures for excluding the receipt of hazardous wastes include random inspections of incoming loads, inspections of suspicious loads, record keeping of inspection results, training of personnel to identify hazardous wastes and procedures for notifying state authorities. All necessary personnel would have to be trained to identify potential sources of hazardous wastes. At a minimum, this should include super- visors, spotters, designated inspectors, equipment operators and weigh station attendants. The training should emphasize familiarity with containers and labels typically used for hazardous wastes and other hazardous materials. 2. The owner would be required to design, construct and maintain run-on/ run-off surface water control measures for specified storm events. 3. Disposal of liquid wastes would be prohibited, including 55-gallon drums filled with liquids and liquids from tank trucks. Household waste, except tank trucks filled with septic waste, are exempt. Leach - ate and gas condensate from the unit could be recirculated only if the unit has a composite (synthetic and clay) liner and a leachate collec- tion system. 4. The owner would be required to maintain historical records, including groundwater and landfill gas monitoring data, inspection records, state notification procedures, and closure and post -closure care plans. Closure and Post -Closure 1. The new regulations would impose significant new requirements on land- fill owners in closing landfills and long-term maintenance. 2.4 2. Owners would be required to develop a closure plan and perform closure in a manner that minimizes the need for further maintenance and mini- mizes the probability of leachate release. 3. Owners would be required to conduct two phases of post -closure care. The first phase would be for a minimum time period of 30 years and the second phase for a length of time determined by the state. The first phase would consist of maintaining the integrity and effectiveness of the final cover, maintaining and operating the leachate collection system, maintaining and monitoring the groundwater monitoring system, and maintaining and operating the gas monitoring system. 4. The second phase must include provisions for groundwater and gas moni- toring. State Level Legislation The Iowa Legislature established a separate branch of IDNR to coordinate various grant programs and lead waste reduction and recycling efforts. The Waste Management Authority Division (WMAD) of IDNR is not a traditional regulatory branch of the Department but instead coordinates the programs noted above. The WMAD is separate from the Water, Air and Solid Waste divisions; however, it has the authority regarding the Comprehensive Plans required by the Groundwater Protection Act, House File 631. Groundwater Protection Act The Iowa Legislature passed the Groundwater Protection Act of 1987 (HF 631) which established the requirements for the comprehensive solid waste man- agement plan. Part I of the solid waste comprehensive plan establishes the state's hierarchy of solid waste disposal options. Part II of the compre- hensive plan requires more stringent landfill design, operation and moni- toring requirements. Comprehensive planning requirements include a schedule for implementation which is coordinated with the IDNR sanitary disposal project permits. The comprehensive planning dates are as follow: 7-1-88 New permits and permit renewals due after this date require comprehensive plans, Parts I and II. 7-1-92 New permits and permit renewals for landfills require a leachate control system. 7-1-94 Permit renewals after this date require steps toward imple- mentation of the comprehensive plan, Parts I and II. 7-1-97 After this date, permits issued for alternatives to landfills or landfills which are part of an alternative disposal system only. 2.5 Part I comprehensive plans are evolutionary in nature, requiring periodic updates as economic considerations and technologies change. At a minimum, the Part I comprehensive plan will be updated and refiled with the Depart- ment every three years (when the permit is due). In all cases, the plans must be implemented by July 1, 1997. The Groundwater Protection Act also established a solid waste tonnage fee. Initially, this fee is $1.50/ton paid to the permit holder for each ton of solid waste received. This was initiated July 1, 1988. 0ne dollar is transferred to the state, and $0.50 is retained by the permit holder for planning purposes. The fees and retainage are on an increasing schedule as follows (Table 2-1): TABLE 2-1 STATE GROUNDWATER PROTECTION FEES Fees Collected Fees Retained FY 1989 FY 1990 FY 1991 FY 1992 FY 1993 $1.50/Ton $2.00/Ton $2.50/Ton $3.00/Ton $3.50/Ton and thereafter $0.50/Ton $0.50/Ton $0.65/Ton $0.80/Ton $0.95/Ton The use of the fees by the state and the permit holder are restricted by the Act. The primary use is directed at planning for and implementation of landfill alternatives. The Act also allows for cost sharing grants administered by Waste Management Authority Division. The Landfill Alternatives Grants are a competitive process and awarded twice per year. A grantee may receive up to $300,000.00 on a 65 percent share. Part II of the comprehensive plan addresses closure and post -closure plans, leachate control plans, financial plans and financial assurance instruments. IDNR will administer the requirements of the Part II guide- lines. 2.6 The Part II guidelines appear relatively close to the RCRA Subtitle D regu- lations. Landfills will be required to meet increased containment regula- tions and include leachate collection and treatment systems. Closure and post -closure plans will need to be developed for all facilities which will outline steps to be taken for monitoring and maintenance of facilities for a minimum of 30 years after closure. In addition, facilities will be required to establish financial assurance mechanisms to provide for closure and post -closure costs and remedial action, if necessary. The impact of the Part II regulations will vary with the size of facilities and the status of facilities in their life span. It is, however, obvious that the costs of landfilling will increase significantly to implement the new regulations. Specifics in the Part II guidelines for landfilling require that the site undergo a hydrogeologic investigation to assure its suitability and provide that the monitoring well system is appropriately and adequately designed and constructed for the particular site. All sites shall have an engineered containment system (liner) consisting of a minimum of 4 feet of compacted clay (1.0 x 10-7 cm/sec - Maximum Perme- ability). All sites shall have a leachate collection and treatment system which is required to be monitored and maintained through the operating and post - closure periods. Closure plans are required which detail final grading and drainage features to prevent erosion, ponding and percolation of water into the site and run- on and run-off controls. The closure plan must be designed to minimize the potential release of pollutants to the air, groundwater and surface waters. The closure must also address leachate collection and treatment, ground- water monitoring, and gas collection and monitoring at the site. Post -closure plans are required to assure that the integrity of the final cover is maintained throughout the post -closure period. Groundwater and gas monitoring must be maintained, along with the leachate collection and treatment system throughout the post -closure period. The current post - closure period is thirty (30) years following closure of the site; however, there is speculation that there will be perpetual monitoring and post - closure activities required. Part II requirements also include the need for an approved financial assur- ance instrument. This financial assurance must be adequate to cover costs of all post -closure activities. Final guidance on this requirement is not yet available; however, there have been recent estimates of $5.00/ton in - place or $200,000.00/acre to cover the financial assurance requirement. 2.7 IOR rev House File 753 The environmental legislation continued in the 1988-1989 session when House File 753 was passed. This legislation, which is known as the Waste Reduc- tion and Recycling Act of 1989, provides prohibitions on various materials from landfills, establishes a schedule for the prohibitions and also estab- lishes goals of 25 percent reduction in solid waste by July 1, 1994, and 50 percent by July 1, 2000. The waste reduction is based on the level of solid waste production as of July 1, 1988. The major prohibitions and schedule are summarized as follows: Banned Material Date Waste Oil Batteries Beverage Containers Unprocessed Tires Yard Waste July 1, 1990 July 1, 1990 July 1, 1990* July 1, 1991 January 1, 1991 *Dealers, Distributors and Redemption Centers. The legislation also deals with plastics labeling, recycling and packaging. In addition to dealing with the banning of land disposal of various materi- als, the legislation also addresses the state's role in supporting alterna- tives. There are numerous funding sources established to encourage waste reduction, including a fee for tires. The legislation also addresses re- cycling issues relating to use of recycled materials. The state will increase the use of recycled materials and establish procedures which will give preference to the use of recycled materials in state contracts. Some of the other features of this legislation include: "State and local agencies responsible for the maintenance of public Establishes a lead -acid battery trade-in program wherein all retailers selling batteries must accept the old battery for disposal. Motor oil retailers will be required to accept used oil or post a Assigns DNR the responsibility to determine a means to store and recycle tires. Establishes a state-wide waste reduction and recycling network. This network will provide an informational base to encourage waste reduction and recycling and will also promote the use of recycled materials used by public and private groups and assist in promotion of recycling pro- grams. 2.8 Market development of recyclable materials is addressed. Public education to promote waste reduction and recycling is addressed. In general, the recent legislation has provided a direction for solid waste management that will necessitate significant changes in our waste manage- ment practices. Our approach to solid waste management will require tech- nological changes which, in turn, may affect societal changes. It is a certainty that the costs of solid waste management will increase. This will be true of any alternatives implemented and will also be true of continuing to landfill. Iowa DNR Rules The Iowa Department of Natural Resources has extensive administrative rules which regulate the implementation of Iowa Code. Section 567, Environmental Protection, and Chapters 100 through 125 address solid waste disposal. Rep/Dubuqua/AA4 2.9 PHI Imq 104 STUDY AREA DESCRIPTION Dubuque County is located on the eastern Iowa border next to the Mississippi River. The county lies about 60 miles south of the northern state line. Dubuque County is situated in a unique location because it borders a tri-state area. Wisconsin is located on the county's northeast border and Illinois is situated at the southeast border. Dubuque County contains three state permitted landfills, all within 10 miles of the Dubuque metropolitan area. John Deere Dubuque Works operates a 35-acre landfill north of Dubuque, and Tschiggfrie Excavating, Inc., operates a 14-acre construction and demolition landfill to the south of the city. The third site, the Dubuque Metropolitan Sanitary Landfill, consists of 214 acres total and 103 acres used for solid waste fill and serves the businesses and residents of Dubuque County. Each of these landfills operate under a permit issued by the Iowa Department of Natural Resources. The IDN4 permit information for the facilities is shown on Table 3-1. The Dubuque Metropolitan Area Solid Waste Agency (DMASWA) is responsible for overseeing the operation of the Dubuque Sanitary Landfill (DSL). DMASWA is the permit holder for the DSL and also the sponsor for the Comprehensive Solid Waste Management Plan, Permit No. 31-SDP-2-75P. The study area is located in Region I, Iowa DNR; and its operation is reviewed by this office: Region I Office Iowa Department of Natural Resources 907 West Main Street Manchester, Iowa 52057 Phone (319)927-2640 The study area consists of Dubuque County which is the current service area of the Dubuque Sanitary Landfill. The DMASWA does not currently intend to regionalize the study by including neighboring counties; however, some sections of this report will address regionalization on a limited basis. The demographics of the study area were developed from the 1986 Statistical Profile of Iowa published by the Iowa Development Commission. Table 3-2 lists demographic information for Dubuque County. A significant portion of Dubuque County's population is urban, accounting for approximately 2/3 of the people. The other 1/3 of the population is rural. The proportionately large urban population is reflected in the overall population density of 153 persons per square mile. Solid waste disposal in the study area has been primarily through landfill- ing; however recently, yard waste composting and voluntary recycling programs have been implemented. Collection systems for the county's residential/commercial solid waste generators are maintained through a mixture of private firms and public haulers. The city of Dubuque provides 3.1 solid waste collection services to its residents and some small businesses. The towns located throughout the county have residential and commercial solid waste collection provided by the town, or a private hauler contracts directly with the residents and businesses. Most of the industrial solid waste is collected and transported to the landfill by one private hauler, BFI Waste Systems, Dubuque District. A small portion is hauled to the landfill directly by the generator industry. Based on the population information from the statistical profile and waste generation estimates, a population centroid and waste generation centroid were computed. Figure 3-1 illustrates the location of the two centroids. The centroid information is used throughout the report as a factor in analyzing transportation economics.

Rep/Dubuque/AA1 3.4 Pel Pal N 10011 IMN w WASTE STREAM ANALYSIS An evaluation of the waste stream composition is a necessary step in solid waste planning. A comprehensive examination of Dubuque County's waste stream was conducted to determine the breakdown of the waste stream into the residential, commercial and industrial components. Further research revealed the constituent make-up of each of the waste streams. This infor- mation was used to develop a plan to meet the state solid waste goals. Information was obtained from landfill tonnage reports, city billing re- cords, a survey of private haulers, published national averages and surveys at other landfills. The landfill has approximately 170 accounts. These accounts consist of residential haulers, business and industry, schools and cities of Dubuque County. Some of the major haulers include: Major Haulers: City of Dubuque Refuse Collection Randy's Sanitary Service BFI Waste Systems Eagle Manufacturing Tschiggfrie Excavating City of Dubuque Street Cleaning City of Cascade City of Dubuque Sewage Treat- ment City of Epworth Modernfold Industries Both urban and rural populations contribute to the residential waste stream, but in differing proportions and composition.

The majority of the above average waste production during the warmer nine months of the year can be attributed to yard wastes and increased construc- tion activities. Yard waste volumes increase dramatically during the wet spring, taper off or decrease during the drier summer, and peak again dur- ing fall as a result of the collection of leaves. Implementation of the new yard waste composting project in Dubuque County should produce more stable monthly waste volumes. An investigation of the available solid waste information reveals the con- stituent breakdown of the total Dubuque County solid waste stream. The breakdown consists of residential, commercial, industrial, construction - demolition and miscellaneous solid waste sources. Each constituent was then broken down into the waste components. The component tonnages are estimates based on national averages and physical studies conducted at other state landfills. The component values in this study are heavily weighted on the sampling results of a study conducted at the Des Moines Metropolitan Landfill. Table 4-1 lists the composition of the solid waste stream. Figures 4-2 and 4-3 illustrate the general compositional break- down. Residential waste accounts for approximately 39 percent of the solid waste entering the Dubuque County Landfill. Much of this solid waste is generated in the city of Dubuque and is collected by the city refuse department. Single-family homes up to apartments are considered residen- tial. An estimate was made for the residential portion of the waste coming from other towns using information from the haulers of each city's waste. The industrial -commercial waste stream accounts for approximately 45 per- cent of the total landfill tonnage. Most communities produce commercial 4.3 TABLE 4-1 COMPOSITION OF THE SOLID WASTE STREAM Residential Commercial/Industrial Percent of Percent of Total Total Total Commercial/ Total Total Component Residential (Tons/Yr) Industrial (Tons/Yr) (Tons/Yr) Paper Corrugated Lawn/Garden Food Wood Plastic Glass Ferrous Metal Nonferrous Metal Miscellaneous 35 5 24 9 2 7 3 3 1 11 9,975 39 13,105 23,080 1,425 14 4,705 6,130 6,840 3 1,010 7,850 2,565 12 4,030 6,595 570 5 1,680 2,250 1,995 11 3,695 5,690 855 3 1,010 1,865 855 5 1,680 2,535 285 1 335 620 3,135 7 2,350 5,485 TOTAL 100 28,500 100 33,600 62,100 4.4 Pun yen >1- Leti Iouri 0'—.T- O W} M —1 m cy< Z C—a L LI CC FIGURE 4-2 4.5 ca Q CC cc Z uu cc Z 3 FIGURE 4-3 MIR ina solid waste, which is waste typically from service oriented businesses. Industry, on the other hand, is generally found in the larger towns and cities. Most of the industrial waste is generated by industries located in the cities of Dubuque and Dyersville. The remaining waste makes up approximately 16 percent of the total and consists of construction/demolition (10 percent), dirt/gravel from street and parking lot cleaning (4 percent) and other miscellaneous waste (2 per- cent). Construction/demolition waste is made up of predominantly rubble from building demolition, dirt and gravel, concrete and metal reinforce- ment, wood, shingles and asphalt. The Dubuque County Landfill currently processes solid about 70,000 tons per year. The landfill has capacity of 4,500,000 C.Y.; the landfill will have years, depending upon cover soil availability. waste at a rate of an estimated remaining a projected life of 30 Solid waste tonnages received at the landfill appear to be increasing over the last decade. Figure 4-4 presents tonnage information from 1977 to 1989. Drawing a best fit line indicates that landfill tonnages increased 10 percent from 1980 to 1990, while census information indicates a county population drop of 8 percent over the same period. This produces a per capita solid waste production increase of 560 lbs./year. While it is pos- sible that the residents of Dubuque County generate more solid waste, it is more likely the solid waste increase is a result of other factors. An increase in industrial activity could be one reason for the increase in solid waste production. Another reason may be that collection efficiencies have advanced over the last decade, resulting in service to a larger por- tion of the population. Those people who were using alternative disposal methods may now have solid waste collection. Figure 4-4A is an illustration of the same information but also projects the tonnage to the year 2000 after implementing successive solid waste comprehensive plans. Also noticeable on Figure 4-4 is the large variation in solid waste produc- tion between some years. Many of these variations can be attributed to one-time events, such as the demolition of a major building or the loss of a large solid waste producing customer. Several events at the county land- fill had a noticeable impact on the waste tonnage. In 1980, Interstate Power Company discontinued disposal of fly ash at the Dubuque County Land- fill. Other events include the disposal of petroleum and sulfur contami- nated soil in 1989 and 1990.

To greater or lesser degrees, economics, environmental and user ease factors all im- pact the success of any landfill alternatives. There are various systems in -place throughout the United States that utilize different approaches to solid waste management that have met with varying levels of success. It should, however, be noted that the implementation of any alternatives to landfilling will increase the out-of-pocket costs of solid waste disposal above those experienced currently. This may be considered a short-range cost increase if long-term landfill related environmental costs are in- cluded in the analysis. The implementation of an integrated solid waste management program must, however, be considered as a new approach to solid waste management and disposal and cannot be simply viewed as a means to reduce costs or "make money" from solid waste disposal. The IDNR hierarchy of solid waste management options describes several steps toward the implementation of an integrated solid waste management program. It provides several considerations that must be included in com- prehensive planning. Although each system will be unique, there are ele- ments that can be universally applied and it is safe to presume that as landfilling alternatives are implemented, new markets and new technologies will result out of necessity. The following text describes various steps in the states hierarchy. The intent is to generally describe the waste management option, its advantages and disadvantages. It is not intended to be all inclusive or in extreme detail due to the need for public involvement in the overall process. As has been noted throughout the study, we believe that whatever "system" is adopted, flexibility must be a major consideration. It is, therefore, intended that the following descriptions provide a starting point which will require additional development through the public information process. WASTE REDUCTION The first element to be considered in the integrated solid waste management plan is waste reduction. Waste reduction education and programs at the residential level are important and should be supported; but to have an even greater impact on the quantity of solid waste ultimately disposed, reduction programs must also apply to the large quantity generators. BUSINESS AND INDUSTRY The DMASWA Agency should appoint an authority whose function would be to study and quantify individual industrial, commercial and institutional waste streams. They would then work with the generators to develop strate- gies to reduce their waste generation. This authority could educate the industries and businesses of the advantages of these programs. The DMASWA authority could provide a clearinghouse function whereby waste from one generator may serve as raw material for another. The Agency should also 5.1 serve as the information clearinghouse to provide a data base for waste generators to implement reduction and recycling programs. This feature may only have measurable affects for larger generators, and it is likely that some state or regional waste exchange program may be necessary. The local Authority could serve as the information source for such an exchange pro- gram. This would be another low -budget, low -profile program that could be accomplished relatively simply. Incentive to industry may be some civic recognition, reduced waste disposal cost and potentially reduced environ- mental liability, depending upon the material impacted. The industries and businesses in Dubuque County should be made aware of waste minimization programs available to them offered by the Waste Manage- ment Authority Division of the Iowa DNR and the Iowa Waste Reduction Center. Waste Minimization Programs 1. Waste Reduction Assistance Program, (W.R.A.P.) 1-800-532-1114 (Recycling Hotline) 2. Iowa Waste Reduction Center University of Northern Iowa 1-800-422-3109 These programs provide free, confidential, nonregulatory assistance to all Iowa businesses and industries. The DMASWA Agency would be responsible for getting this information to the applicable commercial/industrial generators. RESIDENTIAL Even though individual residences are not major solid waste producers, collectively they produce a significant waste volume. Waste reduction programs at this level should be pursued. Each person's attitude toward waste, learned at the individual level, may carry over to their place of employment. Leaving grass clippings on the lawn, avoiding products with excess packaging and buying food in bulk with reusable containers are examples of what the individual can do to reduce solid waste generation. The DMASWA has recently begun a highly visible program that encourages waste reduction. By using the pay -for -bag method for financing the com- posting operation, the Agency has also encouraged waste reduction. Theoretically, the homeowner has a financial incentive to leave grass clip- pings on the lawn or to start backyard composting. Public education on yard waste reduction should also be started. Informa- tion needs to be made available about the advantages of grass clippings left on the lawn and how to start backyard composting. A few ways to "get the word out" include putting a notice in with the residents' utility bills, advertisement in local newspaper and enlisting the help of the schools. There are many local media which can be used. These include: 5.2 Mass Media in Dubuque Area 1. KDUB-TV, Dubuque 2. KWWL-TV, Waterloo (Dubuque Office) 3. WDBQ/KLYV Radio, Dubuque 4.

Outdoor Billboards, Frank Hardie Advertising 15. Over 49 News and Views, Newspaper, Dubuque 16. City Bus Billboards, Dubuque Since the pay -for -bag system encourages waste reduction, the city of Dubuque and other municipalities should consider using this approach for household solid waste. Public education promoting ways to reduce solid waste volumes should be initiated concurrently with the volume -based rates program. "Variable Rates in Solid Waste - Handbook for Solid Waste Officials" is a publication which provides a detailed analysis of variable "can" type and "bag/tag" type systems. This publication is written by Lisa A. Skumatz, Ph.D., and Cabell Breckinridge and is funded jointly by the U.S. Environ- mental Protection Agency, Region 10, Solid Waste Program, and the city of Seattle Solid Waste Utility. A copy of the order blank for this publica- tion is in Appendix E. PROHIBITION OF CERTAIN WASTES Another waste reduction technique that has become publicized is that of prohibition of various materials. By banning various materials from the waste stream, several state and/or local authorities have, in essence, provided a ban on the use of these materials. Perhaps most notable is foam plastics. Numerous areas of the nation have banned the use of foam plas- tics, thus resulting in a reduced waste stream directly from the foam plas- tic product and also indirectly by the reduced waste generation from the production of the foam plastic product. The Agency must view these prohibitions carefully and establish a policy to inform landfill users prior to implementation of a material ban. The Waste Reduction and Recycling Act addresses some of these types of issues and the local efforts to prohibit various wastes may best be handled by working with the state programs. It is unlikely that a local prohibition of any particular mate- rial will necessarily result in measurable environmental changes. As 5.3 state, regional and national programs develop, however, measurable benefits may be achieved. Problems concerning funding and enforcement can be anti- cipated for most "prohibitions," and the local authority should carefully evaluate these factors prior to implementing any bans on a regional basis. A list of possible source reduction programs follows: Consumer Activities Consumers can be encouraged to: Compost yard waste. Buy fewer household hazardous materials. Buy in bulk. Avoid disposable items. Substitute their own nondisposable shopping plastic bags at stores. Repair or donate items, instead of disposing of them. Use long-lasting, energy -efficient light bulbs. Lobby retailers and manufacturers for availability of bulk items and for changes in packaging. Local Government, School and Business Activities These institutions can: bags for paper or Use two-sided copiers. User longer -life tires on vehicle fleets. Buy in bulk, with minimum packaging. Examine and, if necessary, change procurement practices, to maxi- mize source reduction opportunities. Business and Industr"- Activities Local businesses and industries can be encouraged to: Disclose the environmental impact of products and packaging. Change product design to eliminate unnecessary packaging. Evaluate in-house source reduction opportunities that minimize the amount and toxicity of waste that must be treated or disposed of. As a minimum first step to encourage business and industry to reduce waste, responsible agencies should publicize the waste minimization programs for business and industry offered by the Waste Management Authority Division (Iowa DNR) and the Iowa Waste Reduction Center to every business and industry in the planning area. These programs provide free, confidential, nonregulatory assistance to all Iowa businesses and industries. On -site techni- cal assistance helps each site to identify opportunities for waste reduction. A strategy for "getting the word out" to business and industry about these programs should be included in the Comprehen- sive Plan. 5.4 COMPOSTING METHODS The emphasis toward landfill avoidance, due to increased environmental concerns, disposal facility capacities and legislation, has lead to an in- creased interest in composting facilities. Composting is a waste reduc- tion/recycling activity promoted as a waste management option which reduces waste volume and produces a usable end product. Materials that can be composted include leaves, grass clippings and other yard wastes, organic materials separated from collected solid waste, general municipal solid waste, food processing waste, sewage sludge or combinations of these mate- rials. The desired rate of composting, the type and amount of material, whether these wastes are source -separated or not, land availability and the desired level of investment help determine cess. the choice of a composting pro - The Iowa Department of Natural Resources (IDNR) is the government body in charge of composting regulation. A composting facility will be regulated under one of two sets of rules. One set of rules applies to composting only yard wastes, while a second set of rules applies to composting mixed solid waste. Facilities composting yard wastes only must follow less stringent regulations compared to facilities composting mixed solid waste. For instance, yard waste only facilities do not require an operating per- mit. Some of the rules that apply to a yard waste only facility are: The ° ° 0 ° ° ° ° The yard waste must be debagged or bagged in a biodegradable bag. The biodegradable bag must be opened prior to composting. An all-weather surface shall be used for unloading. One acre of land is necessary for every 3,000 cubic yards of yard waste composted. The composting site shall have a slope of 1 to 3 percent. The site may not be located within 100 feet of an inhabitable residence. Finished compost must be analyzed for stability prior to public distribution. If compost is offered for sale, it must be registered by the De- partment of Agriculture. Records must be maintained to document compliance with the com- posting regulations. following are rules that apply to composting • Shall require a permit. 5.5 of mixed solid waste: o Must submit detailed design plans to IDNR. o Composting will be done on an impervious base which has a maximum permeability of 1x10-7 cm/sec. • A detention basin is necessary to collect leachate, and an NPDES permit will be required for treated leachate discharge. o Must have specific operating requirements. • Must draft a closure plan. • Finished compost heavy metals. shall be tested for stability, pathogens and • If finished compost is offered for sale, it must be registered by the Department of Agriculture. Mixed solid waste composting facilities are regulated similarly to a solid waste landfill. Although almost any organic material can be composted, the primary option selected for consideration is yard waste composting. Several features favor yard waste composting and provide justification for this approach to waste management. Leaves are relatively easy to compost. They are easily separated from the waste stream, produce little odor if handled properly and generate a useful end product. Grass clippings are also easily sepa- rated and can enhance the leaf composting process by providing nutrients. Grass should be blended with leaves and partially composted materials to control odors and therefore requires somewhat higher levels of operation. Municipalities vary in size, location, quantity of yard waste generated and availability of land suitable for compost sites. The best approach to yard waste composting varies with application of differing levels of technology. Small communities, rural in character, may consider supplying the waste to farmers for animal bedding or discing into fields, the no -technology approach. The more sophisticated methods that have been developed are referred to as minimal-, low-, intermediate- and high-level processes. Yard waste can also be co -composted with sewage sludge using these same techniques. Alternatively, organic waste included in the municipal solid waste stream can be composted using in -vessel technology. Where time and space are not limiting, minimal technology composting may be most appropriate. In this approach, yard wastes are heaped into large piles or windrows and turned and reformed once a year. Each year, general- ly in the fall, yard wastes are put into separate windrows 12 feet high and 24 feet wide. Much of the pile remains anaerobic for the full year between turnings. Unpleasant odors can be expected prior to the first turning, and serious odors may be released after the first turn. Therefore, a compost- ing site using minimal technology should be relatively isolated from resi- dential or other sensitive areas with a large buffer zone. The material 5.6 should fully decompose in approximately three years. Typically, this mini- mal level process requires one-half acre for 3,000 cubic yards of material for each year in processing. A front-end loader to pile and turn the leaves is all the equipment that is necessary. Low -Level Composting The low-level technology process, which is currently being used in Dubuque County, involves a slightly higher amount of handling. A more rapid com- posting is achieved under conditions in which offensive odors are reduced. This means ensuring adequate conditions of moisture content, oxygenation and temperature within the windrows. Water is added at the beginning of the process to bring moisture content up to approximately 50 percent. It is estimated that 20 gallons of water are needed per cubic yard of leaves. A windrow size of six to eight feet high and 12 feet wide produces proper internal temperatures during the compost- ing activity. After the initial microbial activity, which lasts approxi- mately one month, two windrows can be combined into one providing aeration, keeping the pile aerobic to reduce odors and help maintain proper tempera- ture. A finished, stabilized compost is produced in approximately 16 to 18 months. Shredding and screening are optional steps that can improve the physical quality and appearance of the final product but also require in- creased capital and labor costs. Turning of the windrows can be done with a front-end loader or a windrow turning machine. A rough estimate is that one acre is needed for 3,000 to 3,500 cubic yards of leaves. Additional area is needed for completion and storage of the previous year's material and a buffer zone. Intermediate -Level Composting In intermediate -level composting, the low-level process is improved to speed up the rate of composting. Municipalities or regional centers deal- ing with larger volumes of waste can improve the rate of decomposition by turning the windrows more frequently and adding moisture when necessary. Weekly turnings are generally used which justifies a windrow turning machine. The finished product is available in approximately four to six months. By completing composting in less than one year, storage of unfin- ished and stabilized compost is less of a problem and site size can be reduced. There are increased capital costs due to the special machinery and the required on -site water service. A county or group of communities may consider operating a windrow turner to service several communities, trucking the machine to different sites and thus spreading out the invest- ment. High -Level Composting The high level technology leaf composting process may also be desirable due to space constraints. It involves forced aeration of the windrows with blowers which are often controlled by a temperature feedback system to ensure near optimum temperatures while maintaining aerobic conditions. 5.7 PR Wetting at the start is necessary. The blowers are removed and mechanical turning begins after about one month. A moderate size buffer zone is rec- ommended. The benefit is that composting can be completed in less than one year so space for each year's waste is reusable unless storage is needed. Intermediate and high level sites can be developed into large operations to handle leaf waste each fall, yard waste from spring to fall or co -compost- ing of these wastes with sewage sludge year round. This would generally require full-time employees and higher capital costs for buildings and other site improvements such as on -site water and leachate control systems. It is estimated that leaves and yard wastes comprise 24 percent by weight of Dubuque County's annual residential waste stream and 3 percent of the commercial/industrial waste stream. This indicates that in F.Y. 1988-1989, the landfill received 6,840 tons of yard waste from the residential sector and 1,008 tons from the commercial/industrial sector of Dubuque County, for a total of approximately 7,850 tons of yard waste, or 10 percent of the total waste stream. Leaves are estimated to weigh 250 to 450 pounds per cubic yard and grass clippings slightly higher. A value of 450 pounds per cubic yard is used for all yard wastes. The total volume of yard waste at the landfill during F.Y. 1988-1989 would then be approximately 35,000 cubic yards. Composting regulations require that one acre of land be used for every 3,000 cubic yards of yard waste. So if Dubuque County anticipates the yard waste ton- nage to remain consistent with past years, a 12-acre site would be neces- sary. It is expected, however, that only a portion of the waste volume generated within the county will be taken to the composting facility. Many of the small communities will operate under separate yard waste processing plans. Also, it is likely that more homeowners will leave grass clippings on the lawn because of the higher disposal costs. Therefore, a site smaller than 12 acres will be adequate. IOWA DNR GRANT The Dubuque Metropolitan Area Solid Waste Agency (DMASWA) received a $100,000 grant from the IDNR to operate and study a composting site during F.Y. 1990-1991 (July 1, 1990-June 30, 1991). The composting site, located at the Metropolitan Landfill, was designed and approved by IDNR in June. The initial composting area is approximately 3.5 acres, which can be expanded if more area is needed. The composting facility is located at the Metropolitan Landfill. Opera- tions began on July 1, 1990. The facility will accept grass clippings, leaves, brush and other organic lawn/garden wastes. It will be operated by existing landfill personnel; however, it was necessary to hire an addition- al operator. Equipment purchased for operations at the compost site in- clude a Scat Model 482B compost turner for $39,750.00 and an Olathe Model 865 tub grinder for $66,500.00. Other equipment purchases that may be 5.8 necessary before the first finished compost is ready is a screen that may cost between $60,000.00 and $90,000.00. The composting costs will be covered directly by the residents producing the yard waste. The landfill will charge a $15.00 per ton tipping fee for those people hauling yard waste directly to the landfill and the city of Dubuque will use a pay -for -bag volume -based approach for those customers leaving yard waste at the curb. Residents within the city of Dubuque will be required to use degradable plastic bags for lawn and garden wastes. These bags are sold at local stores for $0.50 each. One requirement of the IDNR composting grant requires the study of this plastic bag's characteristics under composting conditions. At the end of one year, an evaluation will be made whether to continue the use of the degradable plastic or to switch to using paper bags. Brush will be bundled and tied using a six-foot sissal rope "Brush Tie" that will cost $1.00 each and will be distributed the same way as the plastic bags. Yard waste will be collected in the city from April 15 to November 30. The city will use packer trucks owned by the city which are normally held in reserve for regular refuse collection. The yard waste will be picked up on the same days that the regular refuse is collected. Each crew collecting yard waste will collect from three refuse routes. Four new seasonal employees were hired to make up the extra labor. The following are the results of yard waste collections from July through November, 1990. Yard Waste Processed (Tons) July August September October November 114.26 146.64 125.53 254.23 358.35 Also delivered to the composting site during this time period was 358 tons of brush from private citizens. The composting facility received a total of 2,357 tons of yard waste. The composting operation has not been open long enough to produce definitive data, so no assumptions or projections have been made from this yard waste tonnage data. Christmas trees will be recycled in a voluntary drop-off site collection in the city of Dubuque. Trees will be chipped into "Merry Mulch" and returned to the public for use in flower beds. The sanitary landfill will remain open for yard waste composting all year long. 5.9► d Solid Waste Composting Ind Solid waste composting is similar to lawn/garden waste composting. Both may use the same technology, static pile, windrow and in -vessel, and both take advantage of biological decomposition as a means to stabilize the material. Mixed solid waste, however, is more difficult to compost due to the diversity of organic material. Mixed solid waste must also be pro- cessed before composting to remove the inorganic material such as glass, metals and plastic. Composting mixed solid waste utilizes three major steps: processing, composting, and curing and distribution. PROCESSING Processing is the first major step in composting MSW, which starts with recycling. A recycling program will remove many of the inorganic materials before reaching the composting facility. Glass, plastic and metals are common physical contaminants in mixed solid waste compost, many of which would be removed by a recycling program. It is easier and more efficient to remove the recyclables at the source rather than hand picking at the front end. Many composting systems pulverize or chop the solid waste prior to the composting process. If contaminants such as glass go through this process, it becomes very difficult to remove them from the finished compost material. Front-end processing follows recycling. First bulk items, non- compostables, such as white goods, rugs, textiles are removed from the organic material. Then the remaining solid waste is pulverized or shredded to reduce the particle size. This increases the surface area which results in more thorough mixing and enhances the environment for the micro- biological organisms. Size reduction also improves the handling charac- teristics. Many systems incorporate magnetic separation in the processing step. Mag- nets remove most of the ferrous metal remaining after the recycling and front-end hand picking stage. Plastic, glass and nonferrous metal con- taminants are still a problem. Composting is the biological breakdown of organic material. The rate at which the solid waste decomposes depends on the method of composting. The in -vessel composting method, for example, optimizes environmental condi- tions for the biological organisms. With less intensive methods such as windrow composting, the conditions are not optimum, resulting in slower decomposition. Unlike yard waste, mixed solid waste is made up of a wide range of organic material. The various components in mixed solid waste decompose at dif- ferent rates. The degradation process may involve a succession of organ- isms utilizing the byproducts of other organisms. If the waste material lacks required nutrients for any of the variety of organisms or contains a contaminant which would inhibit the organisms, total decomposition will be hindered. 5.10 There are three common solid waste composting methods: 1) in -vessel, 2) aerated static pile, and 3) windrow. The method used in any particular situation depends upon land availability and, in part, by the makeup of the solid waste. In -vessel composting requires the least amount of land and composting time of the three methods. This is a system where the material to be composted is enclosed in a chamber or vessel in which adequate mixing, aeration and moisture control are provided. The environmental conditions of an in - vessel system can be carefully controlled resulting in rapid decomposition. Actual composting time is between one and two weeks. Aerated static pile composting takes place on open land. Moisture and nutrients are added to the processed mixed solid waste which is then placed in piles on a network of aeration pipes. The pipes are connected to a blower which supplies the air necessary for composting. The air circulat- ing in the compost piles provides the needed oxygen for the composting microbes and also prevents excessive heat build-up in the pile. The aerated static pile system is generally less capital intensive than either an in -vessel system or a windrow system. However, there are con- tinuous energy costs from supplying air to the compost piles. Windrow composting is the most land intensive of the three methods. The mixed solid waste is formed into a windrow pile, triangular in shape. The windrows are normally 10 feet high and 15 feet wide. Aeration is accomplished by turning the windrow. The more frequently the windrow is turned in conjunction with moisture and temperature considera- tions dictates the rate of decomposition. Turning machines used in lawn/ garden waste composting can also be used with mixed solid waste windrow composting. Land Requirements Time and land requirements for a composting facility are inter -related factors. An increased composting time results in the need for land to accommodate the incoming waste. Each of the three mentioned composting methods have different composting times and, therefore, variable land requirements. In -vessel composting requires the least amount of time, followed by aerated static pile, then windrow composting. Composting times and land requirements for each of the three systems are listed in Table 5-4. 5.11 a•� MgI TABLE 5-4 COMPOSTING TIMES AND LAND REQUIREMENTS Composting Method Composting Time (Months) Curing Time (Months) Total Time (Months) Land Requirement (Acres) In -Vessel 0.25-0.5 Aerated Static 1.5-3 Pile Windrow 2-6 0.5-1.5 0.5-1.5 0.5-1.5 0.75-2 2-4.5 2.5-7.5 *Based **Based Waste on manufacturer's literature. on 3,000 C.Y. raw solid waste per acre (Unit Weight of Solid 450 Lbs./C.Y.). To keep unwanted material out of the compost operation, front-end removal of contaminants should be included in the integrated program. Many of the noncompostable materials can be removed using a recycling program. Manual and mechanical methods must then be used to remove the remaining contami- nants. The following table shows an estimated projected waste stream prior to recycling and front-end removal of composting contaminants.

The average month would then be 1,670 tons. It is assumed that the yard waste composting system currently running will continue and will not be incorporated with solid waste composting. The composting land requirements are based on the average month tonnage. In -vessel composting, unlike windrow or static pile composting, needs land area primarily for curing. Because of the rapid decomposition involved with in -vessel composting, the vessel itself has minimal land requirements. According to manufacturer's literature, a 100-ton per day facility would require approximately eight acres of land. Land area for aerated static pile composting is greater than for in -vessel. More lard is necessary because of the longer composting time, in addition to curing time. Depending on operational conditions, the necessary land area could reach 20 acres. 5.13 mai As would be expected, the land area necessary for windrow composting is greater than the other two methods. More space is needed, again, because of the longer composting time. Up to 30 acres may be needed if Dubuque County were to use this type of composting system. There are two major considerations involved with choosing a composting system: siting and operational costs. In high population areas, the deciding factor may be siting. If land area is scarce, an in -vessel system may be the only reasonable alternative. In rural areas, like Dubuque County, land suitable for composting is more plentiful; therefore, the selection of a composting system is based more on costs. The costs involved with an in -vessel composting system are somewhat higher than the other two systems. According to a manufacturer of an in -vessel system, a 100-ton per day facility will have a capital cost of $8 million, plus eight acres of land. The annual operation and maintenance (0&M) cost is about $1.2 million, which does not include landfilling rejected materi- al. Financing the capital costs over a 10-year period at a 10 percent interest rate results in an annual capital cost of $1.3 million. The annual capital cost plus the 0&M cost results in an annual cost of $2.5 million. Assuming that the facility will receive compost 312 days per year, the resulting cost is approximately $80.00 per ton processed. Aerated Static Pile The second composting method examined is aerated static pile. The costs for this method are somewhat less than with the in -vessel method; however, more land area is also needed. Estimated costs were obtained from a sup- plier of a packaged static pile system. The estimated cost would be greater than $70.00 per ton, depending on the effectiveness of the recycl- ing program. If recycling removes a large portion of the composting con- taminants, such as plastics and metals, from the waste stream, the costs for front-end hand sorting would be reduced. Windrow composting is a low technology composting technique compared to the other two composting methods. This type of operation would be run similar to the existing yard waste composting system. Since suitable land is likely available, the windrow composting method would probably be Dubuque County's most cost effective composting option. Excluding front-end hand picking, the following is a cost breakdown for windrow composting. 20,035 Tons/Year/450 Lbs./C.Y. = 89,050 C.Y./Year The operation of a mixed solid waste composting site requires the use of several pieces of equipment. Where smaller operations can improvise when it comes to equipment, a large operation must use equipment specially de- signed to perform necessary tasks. The large operations must optimize labor and machinery use to improve efficiency. The front-end loader is used for a variety of tasks. Among these are windrow formation and com- bination, compost turning, moving compost to screening and transferring 5.14 compost to the curing area. A new front-end loader is estimated to cost approximately $60,000.00. Proper composting requires turning on a regular basis. The amount of turn- ing dictates how rapidly the raw material converts to finished compost. A compost turner is usually a machine which is attached to and powered by the front-end loader or a farm tractor. Also on the market are self-propelled turning machines which do not need the aid of a front-end loader. A turn- ing machine would cost about $50,000.00. COMPOST PRODUCT The compost material must be broken down into a fine soil -like texture before it can be distributed. If the material to be composted consists of grass and leaves only, the operation of turning will produce an end product of sufficient quality for public distribution. Mixed solid waste facili- ties, however, may receive substantial quantities of diverse organic mate- rials which require shredding and mixing before composting. Compost is often shredded both at the beginning and end of the process. Several manu- facturers of shredding equipment were contacted to determine approximate costs. Shredding equipment costs for a typical facility were estimated at $90,000.00. The end product should be screened before it is distributed for use. The screening process removes clumps of non -composted material along with rocks and other debris. The material not passing the screen can be returned to the composting operation if it is organic or landfilled. A screen capable of processing 100 C.Y./Hr is estimated to cost about $104,000.00. The machinery previously described makes up the list of the major equipment necessary to operate a composting facility. A summary of the machinery and the corresponding cost is listed in Table 5-5. TABLE 5-5 ANNUAL EQUIPMENT COST Item Capital Cost ($) 2 Front -End Loaders Turner Shredder Screen Total $130,000 55,000 100,000 115,000 $400,000 Total Annual Equipment Cost (Amortized over 10 years at 10%) $65,100 5.15 Poi rn LAND The land requirement for a compost facility is based on the volume of waste that can be put on a parcel of land while maintaining space for operation. A windrow composting site would require about 30 acres of land. After including a 150-foot buffer zone the total land requirement is 48 acres. In Iowa, land is plentiful and costs much less than in many urban areas. Iowa land costs average approximately $2,000.00 per acre. So, a 48-acre site is estimated to cost $96,000.00. Before composting can begin, improvements must be made to the land. One of the first improvements is the preparation of the soil into an impermeable layer. A clay layer or sometimes asphalt is constructed to deter leachate from entering the groundwater. Other improvements include a drainage system, a watering system (usually a well) to wet the composting material, access roads and a fence and gate. Typical land development costs are estimated to be $4,000.00 per acre. Since the actual composting takes place in a 30-acre area the land improvement cost was computed on this area and was determined to be $120,000.00. Both land and land improvement costs total $216,000.00. If capital is obtained at 10 percent over a 10-year period, the resulting annual land cost is approximately $35,200.00. EQUIPMENT A large composting operation uses specialized equipment that remains on site full-time. Buildings should be constructed for storage and mainten- ance of the machinery. Since employees are there full-time, buildings for offices, gate hcuses and scale houses are also needed. To accommodate these needs for Dubuque's facility, a total building expenditure of approximately $260,000.00 is anticipated. A scale is necessary at a large compost site. If private haulers are to be charged a tipping fee, some means of measurement must be provided. A scale also provides weight information for record keeping which plays a major role in site operation optimization. An average modern scale can be con- structed on -site for about $30,000.00. The total annual cost for scale and buildings is $47,200.00 over 10 years and 10 percent interest. To assure that a composting facility runs efficiently, it is important to maintain adequate staff. A large facility of this type requires a full- time front-end loader operator and five full-time facility operators. Labor costs are summarized in Table 5-6. Other miscellaneous costs involve insurance, legal fees, gas and oil, water, supplies, electricity, maintenance and disposal of non-compostable materials. These items are estimated to cost about $40,000.00 per year. 5.16 The total annual costs involved for the composting operation are summed up in Table 5-7. A composting site has an annual cost of $432,000.00. This results in a cost of $4.85 per cubic yard, and assuming the waste has a density of 450 Lbs/C.Y., a cost of $21.55 per ton. IDNR regulations, in many ways, treat solid waste composting sites similar- ly to solid waste landfills. The following quantifies some of the added costs as applied to a 40-acre site, which would result from conforming to the regulations COST FOR 40-ACRE SITE Engineering - Land Development Legal - Land Development Hydrogeologic Report Monitoring Wells Clay Liner - 129,000 C.Y. @ $3.50 Leachate Collection System - 18,000 L.F. @ $7.00 TOTAL Annual Cost (Amortized Over 10 Years, 10%) $ 20,000.00 20,000.00 40,000.00 60,000.00 451,500.00 126,000.00 $717,500.00 $116,800.00 Other Annual Costs Groundwater Monitoring Leachate Treatment Insurance TOTAL TOTAL ANNUAL COST - 8 Wells @ $400.00 $ 3,200.00 5,000.00 50,000.00 $ 58,200.00 $175,000.00 TABLE 5-6 LABOR REQUIREMENTS FOR A SOLID WASTE COMPOSTING OPERATION Labor Description Hourly Wage (Inc.

These extra costs were already added into the cost estimates for aerated static pile and in -vessel. These added costs would increase the cost for windrow composting to $28.10 per ton processed. Because of uncertain liabilities and the high costs involved with mixed solid waste composting, this option should be examined in great depth prior to acceptance. RECYCLING The second step in the IDNR hierarchy is recycling, which is the reuse of natural resources and man-made products. Recycling is a logical process which reuses waste materials to produce new raw materials and products, thus recycling can occur only when waste materials are made into new products and purchased. Limited recycling is already common in the indus- trial sector where scrap from manufacturing processes is collected and reused. It is in the commercial, institutional, and residential waste streams where concentration on recycling of post -consumer wastes should be increased. We have become accustomed to throwing away waste materials 5.18 because of the ease and relatively low cost. We can, however, be retrained to recycle which is exemplified by the success of Iowa's Bottle Bill. An examination of collection, transportation, materials processing and market- ing, as they pertain to Dubuque County's recycling possibilities for com- mercial, institutional and residential waste, was conducted. There are several incentives which make recycling a viable waste disposal activity and which support its inclusion in the comprehensive solid waste plan. Incentives to recycle include: 1. Preserve Natural Resources 2. Landfill Avoidance 3. Reduce Disposal Costs 4. High Value of Some Recyclables Recycling is widely supported. It is almost universally accepted that our natural resources should be preserved for future generations. If recycling can be shown to significantly affect the preservation of natural resources for the future, participation in recycling programs should increase. Landfill avoidance is a second incentive. The removal of materials from the solid waste stream for recycling reduces the volume of waste placed in the landfill, thereby extending the life of the landfill. A third incentive deals with the cost of disposal, which depends on the nature of the waste, the location where the wastes are produced and the regulations governing permissible disposal practices. Disposal costs for industrial generators typically are reduced by recycling, but costs to individuals for recycling post -consumer wastes, may actually increase, at least in the short-term. The final major incentive is materials costs. In general, materials of high unit cost, non-ferrous metals for example, are recycled simply because the recycling costs are usually lower than the costs of buying and refining the raw materials. Materials of low unit cost, such as newspaper, are recycled when disposal costs are high. Recycling of valuable materials is already commonly done voluntarily by industry and individuals. The govern- ing authority must address the issue of recycling less valuable materials from the post -consumer commercial, institutional and residential waste streams, even if at an economic loss, to keep wastes out of landfills and to meet the mandated goals. Some of these materials can, however, provide revenue to help offset the expense of collection, transportation and pro- cessing. Recyclable materials in the commercial, institutional and residential waste streams typically include paper and cardboard, ferrous and nonferrous metals, plastics and glass. When products or packaging made from these materials reach the consumer and, eventually, the end of its useful life, it is discarded along with an almost infinite variety of other products and 5.19 PIM rq materials. It is the mixture of materials which causes difficulties in the return of post -consumer wastes to industry, as small quantities of impuri- ties in many recyclable materials can render them valueless. The commer- cial waste stream typically consists of a large fraction of uncontaminated, recyclable materials which are both readily identifiable and easily separated. The residential waste stream, if processed initially at the individual homeowner level, could also be separated into various com- ponents. The county should consider the advantages and disadvantages of source separated waste when implementing a recycling plan. MARKETING To have a successful recycling program, the material must not only be col- lected but must also be marketed. If recycling is continued as a solid waste management option, the authority will need to establish long-term contracts with materials markets. The law of supply and demand is apparent in secondary materials markets. Where recycling has become mandatory, secondary materials markets often become glutted and it costs additional monies to get materials to more distant markets or fees are charged to accept the materials. The supply and demand must be considered in conjunction with one another, and any recycling program should not only encourage the supply but also the demand, the purchase of products made from recycled materials. Another element of the demand side of recycling will be the development of new markets for secondary materials. The supply side of recycling may be considered on a continuum. The typical homeowner will support recycling if it is shown to be significantly advan- tageous either economically or environmentally. As mentioned, it does not appear from current programs that the economic advantages can be shown in short-range costs. It will probably cost additional money to recycle. It appears, however, that the long-range costs of recycling when incorporated in the integrated solid waste plan can be justified. A curbside recycling program in Dubuque County could collect the following recyclables: 1. Milk and Beverage Containers 2. Glass - All Three Colors 3. Steel Cans depending on current local markets and marketing agreements. There are current local markets for paper, cardboard, metals, plastics and glass. Current market conditions were derived from published regional data and surveys of scrap handlers and purchasers, Table 5-14. 5.20 Paper There is a local market for paper, but this market fluctuates rapidly. Paper is recovered in a variety of grades, including bond papers, mixed office papers and newsprint. To get the highest market prices, paper needs to be sorted and free of contaminants. Corrugated is also recycled local- ly. There is a potential for marketing newsprint as animal bedding in the study area. Ferrous Metals - Nonferrous Metals Both ferrous and nonferrous metals are also recycled within the study area. Scrap dealers will purchase various grades of these metals, which depends on separation into the various types of metal. In particular, ferrous metals should be kept separate from nonferrous metals. Plastics Plastics are currently being recycled within the state of Iowa. The most commonly recycled plastics are HDPE and PET. HDPE is used in milk con- tainers and a variety of other products. PET plastics are used in beverage containers. Research and commercial experience indicate that plastic beverage containers will become a major recyclable material in curbside programs in the near future. Plastics have a high value and are readily and economically reclaimed. Iowa currently has a beverage redemption law which includes PET containers. Until recently, Iowa landfilled 93 percent of these already separated containers; however, H.F. 753 addresses this issue and prohibits iandfilling of beverage containers by a dealer, dis- tributor, manufacturer or redemption center after July 1, 1990. Out -of -State Beverage Containers The Dubuque waste stream contains a significant quantity of beverage con- tainers from Illinois and Wisconsin which are not subject to the deposit requirements in Iowa. These may provide some short-term economic recover- able metals. Action has also been taken on foam plastics manufactured with chlorofluoro- carbons. House File 753 calls for the complete elimination of plastic foam packaging containing chlorofluorocarbons by January 1, 1990, and eliminat- ing these foam plastic products not previously prohibited by January 1, 1998. Glass Glass glass markets exist to an extent locally and in surrounding states. buyers insist on color separated material. They also maintain a 5.21 Most two - tiered price structure in which they pay significantly more for waste glass bottles from redemption centers than they pay for curbside -collected mate- rial. Miscellaneous Other miscellaneous items that can be recycled include motor oil, waste tires, lead -acid batteries and household batteries which have redemption value if handled properly. Locations for oil and lead -acid battery dispos- al listed in Table 5-14 are located in the Dubuque metropolitan area. Outlying communities should establish and publish locations for disposal of special wastes, which include not only oil and lead -acid batteries but also waste tires, household batteries and household hazardous wastes. Even if the collection of these items is unprofitable, they should still be removed to protect the waste stream and environment from contamination. These items are also directly addressed in the Waste Reduction and Recycling Act. Current market prices for the East Central U.S. region are listed in Table 5-13. A spot check in markets in and around the Dubuque area is summarized in Table 5-14. Market prices locally are consistent with the regional prices. METHODS OF COLLECTION There are a variety of methods to retrieve residential recyclables from the solid waste stream. Recycling programs span from voluntary neighborhood drop-off centers to mandatory source separation programs with six to eight separate materials. All of the programs have shown varying levels of success, which are relative to the type of recycling program. Drop -Off Centers A drop-off center is one of the simplest forms of voluntary recycling. Operation of this program involves voluntary participation by residents to drop-off recyclables at a prearranged location. Other volunteers gather the materials for processing and marketing. One example of this type of program is the Boy Scout paper drive where the local troop runs the recycl- ing effort. Financially, the drop-off program is attractive. Capital and operation costs to the city are minimal because the program is run almost entirely on a voluntary basis or by private enterprise. There are, how- ever, drawbacks. Theft and vandalism are not uncommon to an unprotected drop-off center. Because accumulation and transportation of the recyclable materials to the drop-off location is an inconvenience, this type of recycling program typically has a low participation rate resulting in a low solid waste diversion rate. A drop-off program is currently operating at Econo Food supermarkets in the city of Dubuque. The Dubuque Audubon Society, Sierra Society and the Mississippi River Revival jointly operate the facility. The drop-off center is open every Saturday from 9:00 a.m. to 4:00 p.m. and accepts milk jugs, newspaper, aluminum, glass and ferrous metals. 5.22 The Telegraph Herald, a local Dubuque newspaper, financially supports the old newspaper recycling at the drop-off center. The newspaper is shipped to FSC Paper Company in Alslip, Illinois. The Telegraph Herald also purchases raw feedstock with recycled content from the same company. The Telegraph Herald also supports the recycling effort by providing adver- tising space in the newspaper. The 6 1/2-inch by 14 1/2-inch space pro- vides information on materials being recycled in the area and the partici- pating vendors accepting the materials. The bottom of the advertisement gives more details on how to process the recyclables prior to taking them to the vendors. A sample of this advertisement is in Appendix C. The Dubuque Boy Scout Troop, Troop #11, is also active in a recycling pro- gram. The troop makes a collection on the second Saturday of every month and is located at the old Sears store parking lot, Dubuque. They collect newspaper, cardboard, glass, aluminum, steel cans and milk jugs. The cities of Epworth and Dyersville also provide some drop-off site recycling in their communities. Voluntary Curbside Another voluntary recycling program utilizes curbside separation. This process involves asking each residence within a neighborhood to separate recyclables from other trash and set it out to be picked up either concur- rently with the other trash or on a separate pick-up day. If the recyclables are collected at the same time as the other trash, they must be kept separated using specially designed vehicles and/or trailers. The implementation of a curbside recycling program can be expensive. This type of program involves extra man-hours for collection, upgrading or purchasing of equipment such as vehicles and special trash containers, and an extra materials handling step at a recycling processing facility. One benefit received from a curbside program is increased participation. A well organ- ized and operated program can expect voluntary participation rates as high as 30 percent. It is reported that homeowners are encouraged to partici- pate in the program by their neighbors; they want to avoid the stigma of being the neighborhood's nonrecycler. Currently, none of the cities in Dubuque County provide curbside recycling. 5.23 TABLE 5-13 CURRENT REGIONAL MARKET RATES FOR RECYCLABLES (EAST -CENTRAL U.S., JULY, 1990) Paper $/Ton. Baled.

Recyclables, including paper, corrugated, plastic, ferrous metals, nonfer- rous metals and glass, at a typical residence are approximately 65 percent reclaimable and 35 percent nonreclaimable. A 30 percent participation rate in a voluntary curbside separation recycling program, therefore, results in a 20 percent diversion of the recyclable residential waste stream, or 10 percent of the total residential solid waste stream. Because of the fixed costs involved with curbside separation, it may be more practical to imple- ment a program that would increase the participation rate, such as a manda- tory curbside separation program. 5.25 Mandatory Curbside Mandatory curbside separation is essentially the same as the voluntary system, except participation in the program is mandated by a law or ordi- nance. As in the voluntary program, the homeowner is required to separate recyclables and nonrecyclables. The separation can be into numerous com- ponents, depending upon the markets and individual program requirements. However, if the separation requires more than two to three components, accuracy falls off, along with participation due to frustration on the homeowner's part. Success of the program depends upon the cooperation of the residents. If materials can be separated solely as "recycle" and "nonrecycle," the home- owner's job is simplified, resulting in higher participation rates. The recyclables can then be transported to a processing facility where they can be sorted. Participation rates approaching 80 percent are common when the system is kept simple. Processing costs can be reduced by requiring the resident to separate the recyclables, which usually results in lower participation rates. If the homeowner is required to do the separation, time must be provided to phase - in the program. Initially, newsprint, plastic, glass and metals could be required. Other elements could be added in the future after public aware- ness and education programs have been promulgated. Another factor to be considered in the material that will need to be processed. time period to minimize confusion so cessors will have time to change their sudden flow of materials. mandatory program is the volume of A program should have a phase -in that collectors and recycling pro - systems and be able to react to the No city in Dubuque County currently requires mandatory curbside recycling. Hypothetical Example - Dubuque County Table 5-15 depicts anticipated results in Dubuque County from the previous- ly described recycling programs. Effective diversion rates were calculated based on recoverable recyclable material comprising 65 percent of the recyclable waste stream. The parti- cipation rates used were 15 percent for a drop-off center, 30 percent for a voluntary curbside program and 80 percent for a mandatory curbside program. The expected diversion quantities for each recyclable material for each of the three recycling scenarios are listed in Table 5-15. The less intense recycling programs, drop-off centers and voluntary curbside have an insig- nificant impact on the total waste stream. Even mandatory recycling of residential wastes will divert only 7,700 tons per year, or 10 percent of the total waste stream. 5.26 A recycling program removing paper, corrugated, plastic, glass and metals from the residential waste stream when added to the existing lawn and garden composting operation produces the following diversion rates: RECYCLING DIVERSION RATES Recycling Method Total Tonnage % of Residential % of Total Drop -Off Voluntary Curbside Mandatory Curbside 9,390 10,930 15,550 33 38 55 13 15 21 Includes recycling and elimination of lawn/garden waste.

However, even with mandatory recycling, it is unlikely that the year 1994 goal of 25 percent will be achieved without the participation from the industrial/commercial sector. Case Study - Pilot Curbside Recycling Program The city of Waterloo, Iowa, recently undertook a pilot curbside recycling program, in conjunction with Advanced Recycling Systems, Inc., of Waterloo. This study involved five neighborhoods throughout the city, representing 1.5 percent of the city's residential accounts. Participation in the pilot program was voluntary; however, after being selected to take part, the separation of recyclables was mandatory. Each resident involved in the study was given containers to separate recyclables from garbage. After collecting recyclable material and trash from each area, both were weighed. Lawn and garden material was handled separately and is not included in the results. 5.29 The final results are not yet available and should be released in the near future. Preliminary results, Table 5-17, released by Advanced Recycling Systems appear to indicate that a significant portion of the residential waste stream can be diverted from the landfill by using this program.

To implement this type of curbside separation recycling program, a city would need to make major additions and changes to the current collection practices, equipment and staff. For one city in Iowa, the estimates for capital cost to implement the curbside recycling program is approximately $4.7 million. To finance this over a period of 15 years at an 8 percent interest rate would result in an annual cost of $549,000.00. Operation and maintenance costs, which include salaries for drivers, collectors and administrative personnel and the upkeep of the equipment, were projected to be approximately $900,000.00 per year. The city produces approximately 23,000 tons of residential solid waste per year. The following calculation determines the cost per diverted ton to implement this program, assuming 50 percent diversion. 549,000 + 900,000 23,000 * 0.5 - $126.00/Ton Diverted If the program were not as successful as anticipated, the cost per diverted ton would increase. This cost, however, does not consider the revenue from the sale of the recyclable material which would decrease the cost from $20.00 to $50.00 per ton, depending on the quantity and market value of the recyclables. 5.30 The cost of the proposed program is not necessarily representative of all recycling programs. It is possible to begin the implementation of a curb- side separation program with lower costs. The cost estimate for the above project anticipates the use of a six -container system for each residence and new vehicles, which represents a large part of the initial capital cost. Other programs may choose to take a less expensive approach by using existing equipment and recycling fewer items on an initial basis. The three cities of Dike, Grundy Center and Reinbeck in Grundy County are involved in another type of recycling effort using the concept of volume based rates. Recycling in these towns is accomplished by using the pay - for -bag system. Residents purchase specially marked bags which they fill with the garbage going to the landfill. Recyclable materials are set out and picked up separately. This system provides a direct economic incentive for the homeowner to reduce, reuse and recycle. Recycling more results in reduced amounts of trash and the use of bags. Those who refuse to recycle end up paying more. This system may be a good way for many communities to initiate and finance a recycling program. The Agency should investigate this type of system to be used in Dubuque County. MATERIAL RECOVERY FACILITY (MRF) The separation of recyclables from nonrecyclables is the first step in the recycling process. The second step is materials processing at a Material Recovery Facility (MRF). A material recovery facility is a facility where separation of mixed recyclables into specific components and preparation for market takes place. Forms of preparation may involve sorting, shred- ding, crushing, compacting and bailing. Some material recovery facilities are designed to take recyclables already pre -separated by the residents and collectors, while others receive the recyclables in mixed form and then manually or mechanically separate the recyclables into the different com- ponents. Two MRF facilities operating in Iowa are the Northwest Iowa Area Solid Waste Agency in Sheldon, Iowa, and Lee County Solid Waste Commission in Fort Madison, Iowa. Most operating material recovery facilities are located in the eastern region of the United States. The facilities investigated range in size from 40 to 300 throughput tons per day. The smaller facilities for the most part processed metal and glass only, whereas the larger facilities handled paper, cardboard, metal, glass and plastic. Many facilities begin processing smaller quantities of very specific recyclable materials and then expand to processing other recyclables as the operation becomes more efficient. 5.31 COST ANALYSIS An operation and maintenance and capital cost analysis was performed using information obtained on 23 operating or soon to be operating material recovery facilities. As stated earlier, these facilities are located most- ly on the eastern part of the United States so the costs are based on east coast rates. A regression analysis was performed using costs versus tons processed per day. The available information was inconsistent in that of the facilities investigated, some had operation and maintenance cost infor- mation only, some had capital cost information only, while the rest had both capital and operation and maintenance cost information. Figure 5-1 is a scatterplot of capital costs versus throughput tons per day for the investigated material recovery facilities. Several points deviated substantially from the remainder of the data and were eliminated from the analysis. This left 13 data points available for the regression analysis. The plot shows that an increase in throughput tons relates to an increase in capital costs. REGRESSION ANALYSIS A regression analysis was performed using capital cost as the dependent variable and throughput tons as the independent variable. Two of the points that were outliers appeared to be nonrepresentative from the rest of the sample and were eliminated from the analysis. The resulting regression analysis produced an r-squared of 0.81 indicating a linear relationship between the two variables. The following is the equation of the best fit line which predicts capital cost given throughput tons. Total Capital Cost — 443,719.2 + 17,202.9 x Daily Throughput Tons A regression analysis was also conducted using operation and maintenance cost as the dependent variable and throughput tons as the independent vari- able. Again, two points were outliers and were eliminated from the analy- sis. The regression produced an r-square of 0.73 which indicates a fairly good linear relationship between the two variables. The following equation predicts operation and maintenance costs given throughput tons. Annual 0&M Cost — 404,296.4 + 2,957.0 x Daily Throughput Tons Figure 5-2 is a graph of the regression curve (best fit line). This graph indicates that an increase in throughput tons per day is related to an increase in annual operation and maintenance costs. By applying the regression equations to the residential recycling tonnage data, estimated annual costs for an MRF for each recycling method were calculated. Capital costs were amortized at 10 percent over 10 years. These costs are listed in Table 5-18. 5.32 1111101 L 4 7 6 6 4 3 2 1 0 lulls e illlll1 MATERIAL RECOVERY FACILITY CAPITAL COST ANALYSIS CAPITAL COST (_) (MILLIONS) O 60 100 160 200 250 THROUGH -PUT TONS (TPD) 1400 1200 1000 800 600 400 IIIIIIt wlu 1111 N —+— REGRESSION CURVE 111111111 MInii• FIGURE 5-1 i•111N1H 1 11 11011. .11 300 •/111111 360 41411111 111111.

Rep/Dubuque/AB5 5.35 RESULTS The results indicate that economies of scale apply to Materials Recovery Facilities. The larger the throughput tonnage, the lower the cost per ton. The costs per ton for an MRF to process residential recyclable materials appear excessive. The most economical case, not considering transportation costs, is for mandatory curbside recycling. It is apparent that to justify an MRF, commercial/industrial recycling would also be necessary. A material recovery facility may be economically justifiable with the par- ticipation of the commercial and industrial sections in the recycling effort. Accepting that 65 percent of the recyclable portion of the waste stream is reclaimable and participation reaches 60 percent, a capture of approximately 16,000 tons per year can be anticipated An MRF operating 312 days per year with a capacity of 50 tons per day would be necessary to process the recyclables. The following costs for the MRF were computed using the formulas from the regression analysis. Capital Cost a $1,300,000.00 Annual Capital Cost — $150,000.00 (8%, 15 Years) Annual 0&M Cost = $550,000.00 Total Annual Cost — $700,000.00 ($43.86/Ton Processed) A portion of the annual cost for the operation can be offset by revenue generated from the sale of recyclable materials. With proper preliminary separation and reduced contamination, this should yield a better return than when commingled. It should be noted that these results apply most directly only when yearly throughput tonnages are 10,000 or greater. For smaller tonnages, the costs are extrapolated, thus they may not be appropriate. For smaller tonnages, a simpler facility may be more appropriate. A transfer station with col- lection bins, for example, could be used to separate recyclables which would then be transported to a large MRF or to a market. However, separa- tion of materials will need to be done by the homeowner, with only minimal handling at the transfer station. Material recovery facility costs were estimated for smaller facilities handling 30 throughput tons per day and less. The data used to derive the processing costs are given in Table 5-19 and the dollars per ton costs for each recycling method in Table 5-20. OWNERSHIP AND MARKETING Private ownership of the MRF in Dubuque County would be most desirable; however, if the Authority decides to construct an MRF for processing of recyclable materials, it may be advantageous to solicit other counties to 5.36 participate. Regionalization would increase the volume of recyclables which would decrease the capital and operation costs on a per ton basis. The marketing of recyclables in a cooperative effort between Dubuque County and other counties in the region who also have a recycling program would also be beneficial in another way. There are advantages to cooperative marketing both from the buyers' and sellers' points of view. Many buyers are reluctant to deal with small municipalities because of the difficulty in contacting officials and the nonuniform quality of the material they sell. Small municipalities often have trouble finding buyers; and once buyers are found, they have trouble with contract commitments. Both sides profit from a cooperative program. A co-op effort would give the counties more influence when dealing with the buyers, and the buyer could be assured of a more uniform quality product.

Waste -to -energy systems are, however, viable elements in an integrated solid waste management plan. Combustion of solid waste for energy use has been practiced for many years. It is common in Europe, and there are numerous facilities in the United States successfully using solid wastes as fuel. Technology exists that can make incineration of solid wastes environmentally safe in terms of air pollution and ash disposal. Waste -to -energy projects can provide substantial benefits for waste reduc- tion. For typical mixed solid waste, volume reductions of up to 80 percent can be achieved through incineration. This volume reduction obviously extends landfill life. Energy recovery from municipal solid waste can also be a benefit. Solid waste is approximately equivalent to 40 percent of the energy of coal. Simply stated, one ton of solid waste is approximately equal to 800 pounds of coal. Costs The cost of waste -to -energy facilities is significant. The current rule of thumb for a mass burn waste -to -energy system is $100,000.00 per throughput ton. For a 500-ton per day mass burn system, the cost could approach $50 million. For refuse -derived fuel (RDF) systems, the initial capital costs are lower; however, operating costs may be higher depending upon numerous factors such as the amount of preprocessing and/or separation provided, the complexity of the system and location of the energy market. In spite of the potential costs, waste -to -energy facilities will play an important role in the overall integrated solid waste management program. The key to the success of any waste -to -energy system involves three primary factors: 1. Waste Stream Control 2. Energy Market 3. Public Support Waste stream control is essential to maintain that the waste input is delivered to the facility for processing or incineration. Contracts with the energy user will necessitate that a sufficient quantity of waste input be maintained. Since the short-range costs may be higher for the waste -to - energy process, the haulers and/or generators may search for other less expensive options. The Solid Waste Authority can achieve the waste stream 5.38 control through adopting Sections 28-F and 28-G of the Code of Iowa which were instituted for this problem. These sections expand the powers avail- able to intergovernmental (28-E) agencies to ensure waste stream control. Markets The energy market must be a stable, long-term energy user. The expenses associated with the waste -to -energy facility cannot be justified for a high -risk energy user. This is obviously more true of a steam or electric user than an RDF market where the fuel could be supplied to an alternate user; but in either event, the energy market is a critical element in the decision to proceed. The "ideal" energy market should also be compatible with the swings in wastes received. As noted in the waste stream descrip- tion, waste volumes vary substantially. The waste -to -energy facility needs to ensure that the energy market is supplied with the minimum waste stream and also ensure that the facilities are able to process the maximum waste stream. Siting Siting of the facility should be coordinated with the energy market. This is particularly important for steam markets. Practical limits of one mile separation are usable for siting, and this will vary with the steam tem- perature and pressure requirements of the market. For electrical energy markets, the siting is not as critical. It is, however, important that the local power company either be made a partner in the agreement or separate agreements be made to supply distribution capabilities and/or back-up sup- ply. RDF can be transported to end users and is more easily sited than either of the other two energy producing facilities. The haul distances must, however, be considered in any processing facilities to be constructed since they will play an important role in the economics of the waste -to - energy option. It should be noted that implementing waste reduction and recycling programs do not negate the viability of a waste -to -energy facility. Composting and recycling will reduce the waste stream to be processed; however, in some instances, the heat value of the waste stream has actually been enhanced by the first two elements of the hierarchy, and it appears that separation prior to energy production can reduce air pollution concerns. The Waste Reduction and Recycling Act of 1989 requires that recyclable, reusable and materials which will result in uncontrolled toxic or hazardous air emis- sions be removed from the waste stream prior to any process involving incineration. Public Input Public support is essential to implementing any solid waste disposal option. It is particularly important in waste -to -energy because of the relatively high cost and perception of possible environmental risks. A special public education and awareness program will be needed prior to implementation of the waste -to -energy program. The facilities must also be 5.39 PRI MIN designed, constructed and operated to enable the environmental concerns to be minimized. Air pollution and ash disposal for current and potential future safeguards must be incorporated in planning and economic analyses of the facilities. Summary In general, waste -to -energy facilities which appeared to be the technology of the future during the energy crisis should still be considered as one possible element in the integrated solid waste management program. The success of any waste to energy facility is dependent upon the waste stream, energy market and public support. Due to the relatively high costs in- volved, a thorough analysis of this option must be undertaken prior to implementation. INCINERATION A mass burn incineration model was run to analyze the costs associated with this type of facility on a regional basis. Table 5-21 is a present value cost analysis associated with a typical mass burn facility. This example represents a situation where steam will be sold at a rate of $3.00 per 1,000 pounds. It is assumed that the value of the steam will increase at a rate 1/2 percent greater than general inflation. The plant will not gener- ate electricity. Costs The scenario shown uses typical operation and maintenance costs, and capi- tal costs are amortized over 20 years at an 8 percent interest rate. The results are given in dollars per account per year. "Accounts" is merely another expression for households; and for this analysis, the costs were spread over 31,500 accounts. The net costs are given as present value or in year 1 costs. This example shows that during the first year, the cost for this facility would be about $90.00 per account, about $64.50 per account after the tenth year and approximately $29.00 per account after the 20th year. These costs are all based on current technology and the current regulations. At the time when it is appropriate to consider the use of this type of facility, a more in-depth analysis with site specific data should be performed. Summary Dubuque County's waste stream may not be sufficient to supply a waste -to - energy or mass burn facility. A possible alternative to the construction of an incineration facility would be to contract with an existing system. John Deere Works in Dubuque routinely incinerates solid waste produced at the John Deere plant. An investigation of the feasibility of utilizing this facility and other privately owned incinerators to incinerate a por- tion of the county's waste should be pursued. 5.40 TABLE 5-21 PRESENT VALUE COST ANALYSIS DUBUQUE COUNTY HASS BURN INCINERATOR YEAR 1 YEAR 2 YEAR 3 YEAR 4 YEAR 5 YEAR 6 YEAR 7 YEAR 8 YEAR 9 YEAR 10 MIXED SOLID WASTE-TON/DAY 190 190 190 190 190 190 HIRED SOLID WASTE-TON/YEAR 59280 59280 59280 59280 59280 59280 UNIT O&M COST-S/TON 45 47.25 49.61 52.09 54.7 57.43 ANNUAL O&.8 C0ST-3/YEAR 2667600 2800980 2941029 3088080 3242484 3404509 BOND RETIREMENT COST-0/YEAR 2803909 2803909 2803909 2803909 2803909 2803909 ANNUAL COST-S/YEAR 5471509 5504889 5744938 5891990 5046394 6208518 STEAM GENERATED-1000 LBS./YR 355680 355680 355680 355680 355680 355680 STEAM RATE-S/1000 LBS. 3 3.16 3.34 3.52 3.72 3.92 ANNUAL STEAM REVENUE-S/?EAR. 1067040 1125727 1187642 1252953 1321875 1394579 ELECTRICITY GE0ERATED-KWH/7R 10162235 10162285 10162286 10152286 10162286 10162285 ELECTRICITY RATE-3/Kill 0 U 0 0 0 0 ANNUAL ELEC.

One concern is the disposal of ash. EPA has been considering the quality of the ash from mass burn units. There appears to be numerous studies that are inconclusive as to whether or not ash from MSW is hazardous or nonhazardous. It has yet to be finally determined whether or not the ash will be declared hazardous; however, it appears that it will at least be classified as a special waste and require special handling. If the decision is that the ash is hazardous, signifi- cant additional costs will result from the ash handling and disposal. Another concern which should be considered is siting difficulties and regu- latory controls. As mentioned earlier, public opposition may make it very difficult to site a waste -to -energy facility. Future regulation of air emissions is not easily predicted and may cause significant future cost increases. These and other concerns should be closely scrutinized before making a commitment to a waste -to -energy facility. If private industry is inter- ested in mass burning the solid waste, such as John Deere, the party responsible for ash disposal and air pollution control should be determined in the early stages of the negotiations and the appropriate risks assigned in the contract. REFUSE -DERIVED FUEL The production of refuse -derived fuel has been highly publicized recently. The Ames Resource Recovery Plant in Ames, Iowa, is municipally owned and operated and has been in operation since 1975. Fluff produced by the RDF facility is used by the municipal electric plant and burned with coal. After undergoing several shake -down experiences, the RDF facility appears to have established itself as a stable, long-term fuel production facility. In addition to Ames, RDF has been produced in other facilities in Iowa, including Iowa Falls and Cherokee, Iowa. There are numerous vendors of RDF systems. Most of the systems have simi- larities in that the waste is presorted (usually manual) and then goes through a mechanical sorting process to isolate various components of the waste stream into usable and/or recyclable fractions. The primary output from the process is fuel pellets; however, side streams of compost, plas- tics, metals and glass can be incorporated. The estimated breakdown from a typical RDF facility is as follows: 1. Bulky Items and Other Incompatible Waste to Landfills 10% 2. Heavy Plastics to Recycle 5% 3. Ferrous Meals to Recycle 10% 4. Compost 25% 5. Aluminum to Recycle 5% 6. Pellets 45% 5.43 PHI Tipping Fees The facilities are generally set up such that the tipping fees are suffi- cient to cover the capital and operating expenses initially. As recyclables and pellet sales become stable and secure, the tipping fees may be reduced to allow for the other revenues to partially offset the capital and operating expenses. As was previously described in the recycling section of this report, stable revenues from recycling may not be anticipated for some time in the future, although the metals to be recovered from this type of operation would appear to be currently marketable. Compost The compost from the system currently contains too many impurities to make it usable or saleable. The mechanical separation of this fraction of the waste stream is ineffective in screening out various constituents, and plastics and glass can be found in the compost. Currently, this cannot be used as compost and is being landfilled from the Iowa Falls facility. The manufacturer indicates that they are working on solving this particular problem. We would not anticipate a significant revenue from the compost waste stream from an RDF facility even if the current problems with compost quality are resolved. Product The primary product from an RDF facility is the fuel fraction. The fuel can be in several forms: fluff such as the Ames facility, pellets (densi- fied dRDF) such as the Iowa Falls facility, or dust which is being experi- mentally tested for firing with natural gas. The pelletized RDF is undergoing numerous tests to determine its air pollu- tion potential. There are various areas where the dRDF is in use; however, IDNR has not accepted it for widespread use in Iowa to date. IDNR has indicated that if the dRDF is shown to be compatible with one facility having a specified type of combustion process and equipment, it would be considered compatible with other facilities with similar combus- tion processes and equipment. The outcome of this air pollution testing is critical to the long-term viability of the RDF process as a solid waste management alternative. Some research has indicated that feeding lime (possibly lime sludge) into the pelletizing operation actually enhances the performance of air pollu- tion equipment, namely acid gas scrubbers, and reduces the potential for heavy metal leaching from the ash. 5.44 Ash The combustion of dRDF produces an ash. It appears that the ash resulting from dRDF combustion is sufficiently diluted with the ash from the primary fuel (coal) that the hazardous characteristics are not present to any sig- nificant degree, and the potential for heavy metals leaching may be reduced with pH control through a lime feed system in the pellet production pro- cess. If the lime feed is found to significantly enhance the dRDF process and lime sludge could be incorporated as the source, it may serve as a method of disposal for lime sludge which is a significant waste stream in several areas of the state. The possibility of this combination of waste disposal options should be investigated. The implementation of any RDF facility must be preceded by clearance of the air pollution and ash issues. It now appears, however, that the current technology meets these concerns and will be approved in the near future, and this should, therefore, not be a long-term consideration. Costs The capital cost for dRDF processing is estimated at approximately $2.5 million for a 50 TPD facility. The operating costs for the facility based on public operation are estimated to be approximately $26.50/ton initially. If tipping fees are set to cover the entire capital and operating costs of the facility, the tipping fees need to be approximately $48.80/ton. This is based on 10 percent, 10-year capital recovery with no coverage factor. Summary If RDF is approved by IDNR (based on the air and ash tests), it appears that it is a viable solid waste management option. This alternative should be considered as part of the effort to reach beyond the year 2000 solid waste diversion goal. The solid waste authority should pursue a privately owned RDF operation and, upon failure to locate interested parties in the private sector, should consider a publicly owned facility. It is also recommended that only a portion of the waste stream be committed to RDF so that the other waste diversion and reduction techniques in the hierarchy can be vigorously pursued. If the entire waste stream is committed to a waste -to -energy facility, the incentive for other steps is reduced or eliminated, which is not in accordance with the overall intent of the com- prehensive plan. Revenues generated from the dRDF and other pull -off streams could be applied against the tipping fees in the future when they can be successful- ly marketed. 5.45 1. 2. Contract Considerations for a Waste -to -Energy Facility The Agency should agree to provide a waste stream of a specified quantity which should be based on some average term not less than one year. The facility should be responsible for the processing, marketing and disposal of material from the facility. 3. Tipping fees should be specified and the effect of other waste management options should be agreed on in the initial contract. For example, if recycling of paper at a 10 percent level is imposed, what is the resulting tipping fee; similarly, considera- tions for compost, metals, plastic, glass, etc. 4. There should be considerations that limit the waste stream to that under the jurisdiction of the "Authority." 5. Hazardous wastes should not be accepted, and procedures on dealing with these wastes should be delineated. 6. Contract term should be as long as feasible, with optional renewal periods. 7. Responsibility for permitting and testing should be specified. 8. The facility should be required to provide financial records of the operation for auditing purposes that can be easily understood. 9. The facility should be required to have a contingency plan should markets fail. 10. The "rejects" should be specified and limited based on the influent waste stream. 11. The contract may consider negotiating with the facility to be a market for recycled materials from other steps in the hierarchy. 12. The contract should be carefully drafted to cover various scena- rios with respect to default on the part of the facility for nonperformance and/or bankruptcy. The above considerations are only general descriptions of the types of considerations that should be included in the contract. If the "Agency" proceeds with a waste -to -energy facility with a private owner/operator, the contract should be thoroughly reviewed by technical, legal and financial aavisors. 5.46 INCINERATION FOR VOLUME REDUCTION The IDNR hierarchy provides that volume reduction through incineration may be preferable to landfilling the unprocessed waste stream. Reduction, recycling and yard waste composting alone, while effective waste diversion techniques, do not appear to be adequate in reaching the waste diversion goal of 50 percent. If solid waste composting or waste -to -energy facili- ties cannot be developed, then incineration for volume reduction may be considered. The advantages of incineration are the reduction of volume that needs to be landfilled and the cost of an incinerator may be lower than a waste -to - energy or RDF facility. Like waste -to -energy, however, incineration must consider the same problems with ash disposal and air emissions. It is not recommended that this step in the hierarchy be considered at this time. A volume reduction incinerator should not be included in the integrated solid waste management system until the other steps in the hierarchy have been implemented. As mentioned earlier, however, existing systems should be investigated. John Deere; Bremer County Landfill, Bremer County, Iowa; or other operators of incinerators should be contacted to investigate this possibility if it is necessary. LANDFILLING The Dubuque County Landfill began receiving waste in August, 1976. At that time, the expected refuse capacity gave the landfill an approximate site life of 20 years. It was also estimated that there was an adequate supply of soil to be used as cover material. The Dubuque Metropolitan Area Sani- tary Landfill Study, conducted in 1984 and 1985, indicates that the refuse capacity was vastly underestimated in the earlier report and gave an up- dated estimated landfill life of 35 years. The extra capacity, however, contributes to making the landfill site soil short which will require the landfill to obtain soil off -site or to consider daily cover alternatives such as foam or fabric which would require Iowa DNR permit amendments. The landfill is inspected regularly by the Iowa DNR and has never violated the terms of its permit. Originally, the landfill contained approximately 80 acres of land area in which solid waste would be buried. The operation plan divided the area into four phases. Phases 1 and 2 are the southern half of the landfill and have reached an elevation of approximately 940. Phases 3 and 4 were pro- posed to be used for future filling capacity. The landfill will be required to meet new standards set out in the EPA (RCRA Subtitle D) and IDNR (Comprehensive Planning Part II) regulations. Those areas with existing solid waste fill, Phases 1 and 2, will need to be 5.47 upgraded to meet stricter codes; and future cells, Phases 3 and 4, will have to be designed and constructed using more rigid environmental con- siderations. Site improvements that will be necessary include: Filled Areas (Phases 1 and 2) 1. Retrofit a leachate collection and treatment system. 2. Installation of groundwater monitoring wells. 3. Expanded sampling. 4. Closure/post-closure activities. New Cells (Phases 3 and 4) 1. Clay liner (4-foot thickness with maximum permeability of 1x10-7 cm/s). 2. Leachate collection and treatment system. 3. Possibly a system to lower the groundwater table. 4. Hydrological investigation, including installation of groundwater monitoring wells. 5. Annual sampling. 6. Closure/post-closure activities. Continued operation of the Dubuque sive than it has been previously.

The two methods normally used for leachate extraction flow interceptor pipes or the use of wells to pump the leachate. Because of the hazards involved with installing the first system, the Dubuque County Landfill will probably develop a well field to remove leachate. It is difficult to estimate the cost of a retrofit leachate collection system prior to the actual design. An estimated capital cost, however, to install a well field on the 40 acres filled under Phases 1 and 2 may reach $500,000.00. be required in Phases 1 are gravity To estimate the cost of developing new cells under Phases 3 and 4, the following controlling assumptions have been made.

The cost estimate for the facility includes capital, operating, closure and post -closure costs which are projected through the life of the facility but presented in current dollars. The cost estimate is shown in Table 5-22.

The Average Tipping Fee Would Therefore Be: $17,047,700/840,000 Tons — $20.29/Ton* *In addition, the tipping fees would need to reflect the state's ground- water protection fees as shown on Table 2-1. The average tipping fee for the Dubuque County Landfill under "typical" conditions is projected to be $20.29 per ton. This, however, does not include special costs for site -specific problems. The Dubuque County Landfill is soil short, and costs may increase substantially if it becomes necessary to obtain soil off -site. The Dubuque County Landfill may explore alternatives to on -site soil, such as borrow dirt from surrounding farmland and conserving existing on -site soil by using a synthetic for daily cover. The described monitoring program assumes a minimum number of wells at the site. Costs may increase if more wells are added. Sampling costs may also increase if contaminants are detected during the routine sampling period. As Dubuque County implements the comprehensive plan, the volume of solid waste landfilled will be reduced. Since most of the costs described in this report are fixed, decreasing tonnages will make it necessary to increase fees to cover those costs. Rep/Dubuque/AB0 5.50 TRANSFER STATION ANALYSIS An analysis was conducted to determine whether a cost savings would result from the construction of a transfer station. The analysis consists of comparing the cost for collection vehicles to haul solid waste to a dispos- al site (landfill) to the cost for the collection vehicles to haul to a transfer station at a centrally located site. If these cost savings are great enough to offset the cost of operating a transfer station, the trans- fer station would be economically justified. The cities that would benefit from a transfer station were isolated in this analysis. A transfer station constructed at the county centroid would be located further from most of the cities than the landfill. Therefore, for this analysis, the transfer station was located at the centroid of the outlying communities. An analysis was then conducted using the communities that were closer to the transfer station than the landfill. The cities analyzed are Bankston, Cascade, Dyersville, Epworth, Farley, Holy Cross, Luxemburg, New Vienna and Worthington. The location of the transfer station for this analysis is depicted in Figure 6-1. For purposes of the transfer station cost analysis, it is assumed that solid waste collection and disposal would not be affected by the addition of a transfer station. The cost savings for the collection vehicles would result from the shorter transport distance to the transfer station. There may be some additional savings in actuality which would result from reduced wear and tear on the collection vehicles but these vary between vehicles and cannot be predicted with any assurance. A computer model was developed to analyze the economic benefits of a transfer station in Dubuque County. While transport distances and waste generation are unique for each community, there are several factors included that are common to all communities. Dubuque County's final consideration of a transfer station should include a separate study of the area and features desired at the transfer station which is beyond the scope of this study. Some assumptions were made concerning solid waste collection. These include collection truck size, cost and average speed during collection and hauling to the landfill. Other assumptions concern wage rates for drivers and collectors, fuel costs, etc. A 20-yard packer is a popular collection vehicle in Iowa and was used in the model. The cost of a new 20-yard packer truck is estimated to be $65,000.00. The focus of the first phase of the model was to determine the collection vehicle transportation cost. To accomplish this, the analysis was broken down into two areas. The first was to determine the time cost or costs that result whether the vehicle is moving or idle. The second cost, usage cost, results from the actual use of the vehicle. The following two tables highlight time and usage costs. 6.1 • wmui w TABLE 6-1 COLLECTION VEHICLES TIME COST Item Cost ($/Yr.) Depreciation on Truck, Less Tires, Over 6 Years (Straight Line) Driver's Salary Collector's Salary Benefits (25% of Salary) Interest on Truck Investment (11%) Insurance (3% of New Cost) $10,683.33 20,000.00 15,000.00 8,750.00 7,051.00 1,950.00 Total Annual Time Cost $63,434.33 Time Cost ($/Min.)

Yd. and an average vehicle speed during transport of 35 mph, the information needed for the analysis is complete. To determine the transportation cost, the distance from the collection area (cities) to the disposal area was measured from a county highway map. Based upon the waste generation of each area, the number of trips could be determined from which the total travel distance was computed. Multiplying this number by the total usage cost from Table 6-2 results in an annual usage cost. By again using the total travel distance but this time multi- plying it by the average speed results in an annual time which is multi- plied by the time cost presented in Table 6-1, which also results in an annual cost. The total annual cost is then found by adding these two results. It is assumed that the amount of time spent dumping the solid waste at the transfer station is the same as the time spent at the land- fill. A comparison of the total annual time cost was made between the collection sites and the destination disposal site to the collection sites and a centrally located transfer station. The difference between these two amounts is the cost savings for the collection vehicles. Transfer Station Analysis To determine whether a transfer station is a cost-effective transportation alternative, the total savings resulting from collection trucks traveling fewer miles must be greater than the transfer station cost. In the com- puter model, the costs associated with the ownership and operation of a transfer station were examined. The cost of a simple open top transfer trailer is estimated to be approxi- mately $50,000.00 and a tractor is estimated to cost $60,000.00. In this analysis, a transfer station started with one tractor and two trailers. If the tractor was forced to be on the road more than eight hours per day, another tractor and trailer were added to the fleet and considered in the cost analysis. The construction of a transfer station involves a capital investment for land acquisition and construction of the facility. The facility may include a building to house equipment, the building in which the transfer station is located and a scale. The initial site and site development costs for this model were estimated to be $10,000.00 and $200,000.00, respectively. Site development costs anticipate a building, scale, fenc- ing, access, parking and utilities. The typical costs do not include a compactor or push -pit which may be justified in some of the larger facili- ties. Accepting 20-year financing at 8 percent interest, an annual capital recovery cost of $21,389.00 results from the construction of the facility. The following tables list the analyses necessary to compute the other transfer station costs. 6.4 justifiable as a result of increasing fuel costs or innovative facility operations. A transfer station, for instance, may be capable of also being used as a material recovery facility. Rep/Dubuque/AB9 6.7 COMPUTER MODELING SOLID WASTE DIVERSION STRATEGIES A computer model was developed for Dubuque County to evaluate alternative solid waste diversion strategies. The model was developed around a grid system by dividing each county into townships. Each township is assigned a number and is referred to as a cell. A map of the Dubuque County area delineated into cells used in the model is shown in Figures 7-1 and 7-2. This section gives an overview of the construction of the model and its basic capabilities. Using information from the 1980 Census, each cell was assigned a rural and urban population. Based on this information and the county solid waste generation data, solid waste generation is computed for each cell. The residential tonnage is distributed proportionately into each cell according to the population of that cell. The industrial -commercial waste stream is assigned directly to the cell in which the industry is located. At this point, each cell has an urban, rural and industrial waste com- ponent. Each component is then further broken down to represent the com- position of the solid waste. It is possible to divert any part of the waste stream from any of the three components, recycling paper, plastics and/or metal for instance, from the urban waste stream. With the basic information stored in each cell, the computer model can be used to analyze solid waste diversion strategies. The model focuses only on a range of cells that are specified which enables single cities, multiple cities or any combination of individual cells to be analyzed. Diversion strategies that can be assessed include recycling and composting and the siting of transfer stations. RECYCLING ANALYSIS The model can be used to analyze a source separation program. By interacting with the model, diversion quantities of recyclables are varied, along with their current market values. The model can compute the cost to transport the recyclables to a central storage area and the cost to transport the remaining solid waste to a specified destination. The model can also determine the transport costs involved with trucking the recyclable materials to another destination, such as a processing plant or to the recycling markets. The revenue from the recyclables is calculated. Whether curb side separation recycling takes place or not, the remaining solid waste is accumulated at any specified destination. At this point, three situations can be analyzed: 1) recycling, 2) composting and 3) transfer station. 0 m 7.1 m m H FIGURE 7-1 1011 PR PR Poi PRI Mili rid T90 T89 T88 T87 DUBUQUE COUNTY OUTLINE COMPUTER MODELING CELLS I 2 3 4 I 5 6 7 8 9 10 II 12 13 14 15 16 17 R-2W R-1W R-IE FIGURE 7-2 R-2E R-3E NOTE: INTEGER TOWNSHIP AND RANGE N ERS ARE REFERENCED FROM THE CENTER OF EACH CELL. The model is designed to analyze a situation where recycling takes place at an initial destination which is typically the centroid or landfill. The model computes the quantity of material that will be recycled and the market value that can be expected. It also has the capability to recycle from a given separate waste stream entering the recycling facility before and after being mixed with the previously mentioned waste stream. The model computes the costs that will be incurred from the transportation of the recyclables to the market and the revenue that can be expected from the sale of the materials. With this information, the net cost to recycle is projected. COMPOSTING ANALYSIS Another form of solid waste diversion evaluated is composting. The operator inputs the percentage of food, paper/cardboard, lawn/garden and miscellaneous waste that will be composted, the composting site location and the computer model generates composting site information. Among the information determined by the model is the amount of land area needed to compost the given quantity of material and the resulting annual capital and operation and maintenance costs and transportation costs can be derived. TRANSFER ANALYSIS A mixed solid waste transfer station is the last process analyzed by the model. If the recycling and composting facilities are not already at a final disposal site, such as a regional centroid or landfill, then the model examines the use of a transfer station to transport the remaining solid waste to a final destination, which could be a landfill or waste -to - energy facility or a material recovery facility for recyclables. The model was used to determine the population and garbage generation centroids. The model has the flexibility to calculate the centroid of any combination of cells. With all the data input, the model is then used to determine annual capital and operation and maintenance costs for the transfer station, along with the costs to own and operate the transfer tractors and trailers. There were several input variables that were assigned typical values. These variables were used in determining transportation and related costs and include: Garbage Compacted in Packer Trucks 650 Lbs./C.Y. Lawn and Garden Waste 450 Lbs./C.Y. Curbside Recyclables, Mixed 300 Lbs./C.Y. Average Packer Truck Capacity 20 C.Y. Average Recycling Vehicle Capacity 20 C.Y. Transfer Trailer Usable Capacity 75 C.Y. SCENARIO NO. 1 The first run involved yard waste composting and recycling. It was assumed that the total yard waste stream was composted at the county landfill. The necessary composting area for this volume is 10 acres or 21 acres with a 7.4 buffer area. The annual site cost was computed to be approximately $178,000.00. Paper, cardboard, plastic, metals and glass were recycled in this analysis. Assuming that 40 percent of the recyclables were removed from the waste stream produces a total removal of 23,800 tons per year. The model derived costs to transport the materials to market and the return received from the sale of the recyclables. SCENARIO NO. 2 The second scenario involves the same input information as the first, except MSW composting is analyzed in place of yard waste composting. In this situation, 80 percent of paper, cardboard, food and miscellaneous waste not captured by recycling is composted. Again, the composting opera- tion is sited at the county landfill. In this case, 24 acres are needed to compost 21,000 tons per year of mixed solid waste. The annual site cost was estimated to be approximately $430,000.00. RESULTS Other information, including costs and waste volume breakdowns, not men- tioned here can be found in Appendix A. Information generated by the model, along with information in the report, was used to prepare the Com- parative Cost Analysis (Appendix B). Rep/Dubuque/AC4 7.5 PUBLIC AWARENESS - CITIZEN PARTICIPATION Implementing a plan to change or alter the way we handle solid waste disposal requires full cooperation of all interested parties and the in- volvement of public officials, private collectors, landfill operators, and most of all, the general public. The Dubuque Metropolitan Area Solid Waste Agency has the responsibility of focusing all parties together toward the common goal of implementing landfill alternatives in future solid waste management systems. Local government leaders need to fully understand the problems of the pre- sent system of disposal and the types of changes that best address those problems. Private collectors also must be fully informed so that they can comply with proposed changes in a timely and efficient manner. The general public needs to know what is being proposed, what is expected of them, and how can they assist in solutions to the problem. Increasing fees, even if necessary, without a full understanding of why is not generally well received or supported by the public. The public should be informed of the benefits to the economy, public health and the environment of solid waste management alternatives to landfilling. PUBLIC EDUCATION An increased awareness relative to solid waste issues and necessary changes should be the goal of the public education program. This needs to be an on -going process and is an integral part of the Comprehensive Plan. The Groundwater Protection Act includes a policy for public education and also charges the director (of DNR) to work to develop a program to be included in grades seven and eight of Iowa schools covering water quality issues. MASS MEDIA Direct contact with the public can be extremely beneficial in implementing changes needed to improve the solid waste disposal system. Localizing what needs to be done increases success with any project. A Citizens Advisory Group or Technical Advisory Committee with wide representation can be an excellent sounding board and can generate public awareness. The mass media should be kept informed and should be encouraged to cover as much news and information about the issues on the local scene as possible. A news card sent to every household periodically by way of utility bills covering solid waste information is often helpful. Providing service clubs programs on the environment should be used in the public education effort, along with school projects demonstrating the recycling possibilities and elimination of disposables. The general public is by far the most effective source of ideas and projects toward implementing change in any on -going program. They are the final voice in reducing dependence on "disposables", purchas- ing recycled and recyclable materials, and urging companies to change the packaging of products. 8.1 CITIZEN'S ADVISORY GROUP A Dubuque County committee was formed for the purpose of making recommendations to DMASWA concerning recycling and solid waste issues. The committee held public meetings on October 10, 1990, October 18, 1990, and October 24, 1990. A fourth meeting is planned for January, 1991. The committee members are: Ernie Akers Council Member, City of Epworth 104 - 1st Street, S.W.

The meetings were held on September 12, 1990, in Peosta and October 3, 1990, in Dubuque. IOWA DNR The Iowa Department of Natural Resources has educational literature avail- able for local governments as well as individuals. Many of the materials available for governments are implementation guides for solid waste pro- grams, such as recycling, composting and household hazardous waste. The DNR can also give advice on other sources of information, such as manuals and books, reports, magazines and journals, school curriculum guides and information from other government agencies. These sources of information may be helpful to the DMASWA as they plan and implement solid waste programs.

Rep/Dubuque/AA9 8.3 ..6111111111111111111111, PROPOSED INTEGRATED MANAGEMENT SYSTEM The previous chapters of this report provide a description of Dubuque County, its population and waste stream, and the various options available in the hierarchy of waste disposal alternatives. Preliminary results indi- cate that solid waste management will become a more significant component in the budgeting considerations of the area's entities. Alternatives to landfilling will involve significant cost increases for collection, trans- portation, processing and disposal. Landfilling costs are also expected to increase significantly as more stringent design, development, operation and monitoring requirements are enforced. Planning and implementation of the comprehensive waste diversion strategy must include careful consideration of the potential effects of variables which cannot be controlled or accurately forecasted or predicted. For example, there will be a major impact on the cost of landfilling due to the recent environmental legislation increasing groundwater monitoring require- ments. It is not possible to predict how policy on other environmental issues, such as in regard to air pollution, may change and impact the cost- effectiveness of waste -to -energy or incineration facilities. The waste stream's quantity and composition will change as society's attitudes toward waste disposal change, population trends change and waste disposal prac- tices change. Energy and recycled materials markets will fluctuate. Industrial and commercial waste generators may become more involved as their current methods of disposal become more costly. Transportation and energy costs will probably increase as they did in the 1970s. These types of variables should be considered before making final decisions. Each disposal option has considerations that make reliance on a single technology impractical. The system must maintain flexibility by having a variety of options available. When problems occur with one technology or demand decreases in one option, the waste can be supplied to another for effective overall waste management. EDUCATION Education is vital to the success of a solid waste program. The education process involves getting the information to the targeted group and present- ing it in such a way as to alter that group's habits. A variety of edu- cational strategies should be used when implementing a comprehensive solid waste plan. Schools To ensure long-term success, the most important place to start education is in the schools of Dubuque County. Adults are more likely to comply with a solid waste program because it is the law, not because they are concerned with landfill shortages and environmental pollution. Children are open- minded and can more easily be taught to care about solid waste issues. 9.1 With the importance of those issues ingrained in them, they should grow up to be enthusiastic adults who care about solid waste issues because they believe it is important. The Iowa DNR has an environmental education facility which could assist with a program and provide inforamtion. Contact: Springbrook Conservation Education Center R.R. #1 Box 53 Guthrie Center, Iowa 50115 Phone (515)747-8383 They also have a Groundwater Education Coordinator in the Des Moines office which provides assistance. Call (515)281-5135. An educational program should be set up in the schools in Dubuque County. The following is a list of some programs or guides available to the educa- tors to assist in teaching solid waste issues: School Curriculum Recycling Study Guide (Grades 4-12), Iowa Department of Natural Resources, Wallace State Office Building, Des Moines, Iowa, 50319-0034, (515)281-8941.

Iowa State University Extension at 2600 Dodge Street, Plaza 20, in Dubuque, Iowa, 52001, (319)583-6496, offers publications on environmental issues and will provide assistance with solid waste educational programs. There are a variety of ways to communicate a message to a large number of people. Advertising or public service announcements using local media is one way to "get the word out." Another method would involve the distribu- tion of fliers through the mail, for example along with the utility bills, by handing them out at convenient locations or by direct mail. These should be printed on recycled paper. 9.2 Public awareness is important to ensure initial and ongoing success of the solid waste plan implementation. Any program for Dubuque County should first consider the methods that will be used to educate the public so they have the information necessary to implement the project. The following table lists educational and promotion ideas which may be used. IDEA LIST FOR WASTE MANAGEMENT ALTERNATIVES EDUCATION AND PROMOTION Newsletters Broadcast or Print Public Service Announcements Consumer Brochures/Pamphlets Special Events * "Recycling Week," Etc. Bumper Stickers Posters Press Kits Premiums * Mugs, Frisbees, Key Chains, Calendars, Litter Bags, Etc.

Dubuque County should coordinate and promote a household hazardous waste cleanup day. Give the residents the opportunity to take unwanted household hazard- ous wastes to a location in each community. The Agency can then dispose of the waste properly. This type of program should be conducted at least on an annual basis. The Waste Management Authority Division administers a Toxic Cleanup Day Grant Program. This is a competitive process and grants are awarded twice per year. The Agency should apply for this grant. The Iowa DNR has an Emergency Response phone number, (515)281-8694, in case of an emergency with hazardous materials. The city of Dubuque Fire Depart- ment also has a Hazardous Waste Response Team for local emergencies. Motor oil, lead -acid batteries and tires are banned or will be banned from disposal at the sanitary landfill. Each community should have a location where the general public can dispose of waste oil. The DMASWA should investigate potential locations for oil disposal. Service stations and automobile lubrication stations would be potential sites for waste oil receptacles. If a private location cannot be found, the local governments should have waste oil collection included with the hazardous waste cleanup day. After disposal locations are established, the public should be informed of these locations. Lead -acid batteries are also banned from the landfill. Dealers selling new lead -acid batteries to the public must accept the old batteries in return and recycle or dispose of them properly. This will take care of the major- ity of old lead -acid batteries; however, batteries needing disposal which will not be replaced remain a problem. Again, the hazardous waste cleanup day may be an opportunity to collect and properly dispose of these lead - acid batteries. The public should also be made aware of recycling programs within the community. K-Mart stores, for instance, currently buy lead -acid batteries for recycling. By July 1, 1991, unprocessed waste tires will be banned from disposal at the sanitary landfill. The authority should pursue markets for waste tires, such as highway construction, playground conditioners and fuel. If markets are unavailable, the tires can be landfilled if they are first processed. All efforts should, hoewver, be made to develop markets for the processed tires to avoid landfilling. Medical wastes do not make up a significant portion of the waste stream; however, special handling and disposal of medical waste is necessary. Currently, medical wastes produced in Dubuque County are incinerated at Mercy Medical Center in the city of Dubuque. Incineration at this facility should continue to be the method of medical waste management. To ensure 9.4 that all infectious medical waste is removed from the waste stream entering the landfill, the DMASWA should adopt a policy prohibiting the landfilling of unprocessed infectious medical wastes. A notice and educational mate- rial detailing the prohibition should then be sent to the facilities that produce the wastes. WASTE REDUCTION The city of Dubuque currently encourages waste reduction by partially financing the county composting operation with the pay -for -bag system. This gives homeowners an incentive to leave grass clippings on the lawn or to backyard compost. Educational programs should be initiated to further encourage homeowners to use these methods of lawn/garden waste management. Since volume -based charging, such as the pay -for -bag system, gives the solid waste producer an incentive to reduce, municipalities in Dubuque County should use volume -based charging for other solid waste. This can be accomplished by using a pay -for -bag system similar to the one used for lawn and garden waste or the solid waste can be measured during collection. The second method would increase collection time and costs. At the same time, the public should be informed about acceptable methods of reducing gen- erated wastes. A recycling program can also be enhanced by volume -based rates if the charge for collection of recyclables is less than the charge for regular garbage. Volume -based charging may be simplified if stickers or tags are used to label the residents' solid waste. A sticker or tag can be sold through the Agency and distributed to the public. Each solid waste generator will be required to attach a sticker or tag to the solid waste container before it will be collected. This system works the same way as using a stamp to pay for a mailed letter. It appears that volume reduction would initially be most effective on the industrial/commercial level. Paper waste makes up a large portion of the total waste produced by businesses and schools; therefore, they should be encouraged to use two-sided copy machines. Other waste reduction tech- niques discussed in Chapter 5 should also be encouraged. A detailed waste analysis should be performed by each industrial and com- mercial generator. The DMASWA should establish a clearinghouse to study this information and then advise the generators on volume reduction tech- niques. Programs available through existing agencies, such as the Waste Management Authority Division (IDNR) and the Iowa Waste Reduction Center at the University of Northern Iowa should be made available to the industrial/ commercial waste generators. YARD WASTE COMPOSTING Realizing the urgency of removing yard waste from the waste stream, Dubuque County has recently implemented a yard waste composting operation. Com- posting should continue to be the method of yard waste recycling, and 9.5 w UNI MMII Dubuque County should continue to promote its existence and use. Promo- tions should also encourage backyard composting or leaving grass clippings on the lawn. RECYCLING Dubuque County evolves into a started with a Dubuque. This raises public time, markets opportunities DROP-OFF should use a recycling strategy that starts simple and more complex program as necessary. Dubuque County has drop-off recycling system with several drop-off centers in should be expanded to other communities in the county. This awareness about recycling at a minimal cost. At the same can be developed and an investigation of potential recycling in the commercial/industrial section should be conducted. The drop-off program should start collecting one to three different recycl- ing materials such as plastic, metal cans and glass. A low technology MRF, such as a warehouse, should be set up to process the recyclables until a more advanced MRF is built. Drop-off recycling success does not come from diverting large quantities of solid waste from the landfill but from the education of the public about recycling and the municipalities about mate- rials processing and establishing markets. CURBSIDE A voluntary curb -side separation recycling program should start within a year of the drop-off program. This should involve both the residential and commercial/industrial sectors. Again, keep the system simple at first, then include more items in the future as people become more proficient recyclers. The amount of presorting on the homeowner's part will depend on public support of increasingly complicated systems. A more advanced material recovery facility may be necessary to process the increased volume of recyclables. A large portion of the industrial/com- mercial waste stream is collected privately by one company. The Agency and/or cities should apply for Landfill Alternatives Grants from Iowa DNR to assist in funding waste reduction and recycling programs. MRF The material recovery facility should be privately owned and operated. Alter Recycling, Browning -Ferris Industries (BFI) and Dittmer Companies, Inc., have expressed interest in ownership of an MRF to process the county's recyclables. These three companies have experience and contacts in the recycling field The Agency should send requests for proposals for the MRF to these three companies and other interested parties at least one year prior to the implementation of the recycling program. 9.6 To assure quality control, the MRF should be regulated by the Agency. A contract between the owner and the Agency should be drafted and include the following guidelines: Tipping Fees - Rates Charged to Customers Unaccepted Materials o Quantity and Quality of Materials O Necessary Processing o Hours of Operation o Market Information 0 Service Area - Just Dubuque County States Have Access to the Facility O Fate of Nonrecyclable Residuals or Will Other Counties and 0 Contingency Plan for the Unanticipated Shutdown of the Facility DMASWA should own and operate an MRF in the event that an acceptable pri- vate owner cannot be found. The facility should be sized in anticipation of volumes from a mandatory recycling program and have a convenient loca- tion. Because of the cost of an MRF and the marketing leverage gained from larger volumes, Dubuque County should solicit other communities in neigh- boring counties to take part in the recycling program. By 1993, an evaluation of the recycling programs should be made to deter- mine if a mandatory system is necessary. If it is needed, an ordinance must be passed mandating participation in the program. RECYCLED PRODUCTS The DMASWA, Dubuque County, city of Dubuque and all cities in the compre- hensive plan should support the last step of the recycling cycle, purchase of products produced from recycled materials. The Agency should develop a program to promote the use of recycled products to each business and organ- ization in the study area. This should begin with local governments. Paper and other recycled products should be purchased in place of their virgin counterparts. Initially, the recycled materials may have a higher cost; however, supporting the markets now will help bring prices down in the future. Examples of recycled products are recycled paper, tire derived fuel, glass aggregate asphalt, fly ash used in concrete, recycled plastic products and yard waste compost. It is also important the manufacturer of these pro- ducts use "post -consumer" materials and not claim factory waste as a recycled product. RUBBLE FILL AREA Construction/demolition waste makes up a significant portion of the Dubuque county waste stream. A large portion of demolition waste is rubble. Rubble free of other construction/demolition waste is not considered solid waste and can be used in such activities as road construction, erosion control or fill material. Construction/demolition wastes must be processed 9.7 at a permitted solid waste disposal facility; however, the Agency should investigate the possibility of removing the rubble from the other construc- tion/demolition waste for other uses. If nothing else, the rubble should be separated and stockpiled elsewhere to help in the effort to reach the solid waste management reduction goals. MIXED SOLID WASTE COMPOSTING Dubuque County should be capable of reaching the 1994 goal of 25 percent using waste reduction, composting yard waste and recycling the residential and commercial/industrial waste streams. It is unlikely, however, that the year 2000 goal of 50 percent can be obtained without the addition of another solid waste management program. Dubuque County should investigate mixed solid waste composting as a means of achieving this goal. The MSW composting operation should concentrate on producing a high -quality compost that would be easily marketed or land applied. The targeted waste should be paper and cardboard not captured by recycling, food and wood waste. Rejected materials that would be recycled or landfilled would be plastic, glass and metals that were not captured in the recycling program and the other noncompostable items. Dubuque County should compost these items using the same technology used for yard waste composting. Many of the equipment needs of the MSW compost- ing site could be met with the same equipment used at the yard waste fa- cility. The two composting operations; however, should be kept separate. The engineering, land development and permitting requirements are more extensive with mixed solid waste composting than with the composting of yard wastes. Dubuque county, therefore, should start planning and design of the site by 1995. The first stage would involve locating a suitable site, determining a plan to remove noncompostable material and application for the required permits. Market research would also be started at this time. The second stage will involve engineering design, construction and program implementation. WASTE -TO -ENERGY It is not recommended at this time that Dubuque County pursue the third step in the waste management hierarchy, waste -to -energy. The high capital costs associated with mass burn incinerators, along with the uncertainties associated with future air pollution and ash considerations, contribute to significant risks associated with this technology. If, however, a private firm expresses interest in burning solid waste at an existing facility, negotiations with these industries should be pursued. 9.8 REFUSE -DERIVED FUEL An RDF facility does not currently carry the same degree of risk as does a mass burn unit. There are, however, significant risks associated with this type of technology that must be addressed. The contract with a private operator for the RDF facility must be carefully drafted to cover a full range of legal, financial and technical issues. Dubuque County should not pursue RDF for waste management unless the mandated goals are not reached using other methods. INCINERATION FOR VOLUME REDUCTION Dubuque County should anticipate difficulty in permitting this type of facility. This process should be considered as a low priority method to reduce landfill waste volumes unless a private firm expresses interest in incinerating the solid waste at an existing, privately owned facility. At this time, this alternative is not recommended. LANDFILLING This ultimate disposal technology will comprehensive plan for solid waste ma Dubuque County landfill can anticipate implementation of the solid waste plan continue to be a viable part of the nagement. At current volumes, the 30 years of remaining space. The will increase the landfill life. The Agency is currently in the process of developing Part II of the Compre- hensive Solid Waste Plan. Part II includes the requirements of Subsections 4 and 5 of State Code 455B.306, which addresses closure and post -closure plans, leachate control plans, financial plans, and financial instruments and must be completed prior to renewal of the landfill permit. The hydro - geologic investigation currently being conducted at the landfill will produce information necessary in Part II of the Comprehensive Plan. Part II of the Comprehensive Plan should be implemented after its completion and acceptance. CHART The following organization chart demonstrates the proposed solid waste management plan for Dubuque County. This example anticipates that rubble will not be removed from the construction/demolition waste and will be landfilled. The lawn and garden waste is composted and the remaining waste enters the recycling process. Nonrecyclables and recyclables not captured in the recycling program are composted. The lawn and garden composting, along with recycling, will be implemented prior to the year 1994. As shown on the chart, these two activities will remove approximately 23,800 tons from the solid waste stream each year, surpassing the 1994 goal of 25 percent. The final step, MSW composting, removes another 26,370 tons per year, for a total of 50,180 tons per year diverted from landfilling. Implementing this plan with these results will enable Dubuque County to reach the 50 percent waste reduction/recycling goal.

We know that environmental factors may be closely related to public health in some respects; and therefore by manag- ing environmental impacts, we can affect public health. The current method of solid waste management in Dubuque County is primarily through landfilling. When this process was initially developed, the intent was generally to provide a space for solid waste disposal and provide suf- ficient cover to minimize litter, vermin and fire hazards. These are still significant considerations in operating a landfill; however, there are additional concerns regarding potential groundwater and surface water con- tamination. Groundwater contamination has become a significant issue in landfill sit- ing, design and operation. H.F. 631, Part 2 - Comprehensive Planning, requirements include liners, leachate collection and treatment, expanded monitoring, closure and post -closure plans. These more stringent landfill requirements are generally directed at reduction of potential groundwater contamination, early detection of any release should it occur and remedia- tion of problems before they can become more widespread. Implementation of these more stringent landfill requirements will increase the costs of this type of disposal; however, it will also improve the environmental effects of landfilling as a technology. The waste management hierarchy established by IDNR is, in part, related directly to environmental effects. Implementation of a comprehensive plan will ultimately reduce landfilled solid waste and the hazards associated with landfilling. WASTE REDUCTION The first step in the hierarchy is waste reduction, and the current types of activities anticipated in this step would result in environmental benefits. It is obvious that if waste is not produced, the environmental affects from their disposal is a positive one. Landfill life is expanded, and potential problems from landfills are generally reduced as a result of waste reduction. Some of the materials proposed for banning through waste reduction programs are generally targeted at some of the more environ- mentally questioned materials. Chloroflurohydrocarbons in foam plastic, for example, which is banned in the future, is a documented environmental problem from its manufacture. As waste reduction programs are instituted, they must be evaluated on their overall benefits; however, in general, they will provide positive environmental impacts. RECYCLING Recycling and re -use is another step in the hierarchy which appears to have significant positive environmental effects. Through recycling and re -use, raw materials and energy are saved and landfill life is extended. The type of recycling program will have some impact on the level of energy savings as the collection of solid waste for recycling will involve expenditure of energy, labor and equipment. Market locations also are factors in the environmental benefits as they relate to energy and equipment expenditures to move the materials to the market. Developing local markets will reduce transportation costs and corresponding environmental factors; however, the materials processing required by the market may result in significant local environmental effects. For example, if a paper mill were to develop in the Dubuque County area to recycle old newsprint (ONP), significant energy use, air pollution concerns and water needs will result. Although there are significant needs for ONP recycling, the environmental drawbacks of an ONP processing operation must be considered in the overall management program. There are numerous possibilities when recycling is viewed in this type of program; however, in general, recycling and re -use have the potential to provide significant environmental benefits. One of the waste reduction and recycling programs that is recommended is yard waste composting. This fraction of the Dubuque County waste stream represents a significant volume which is currently being landfilled. In the landfill, this highly organic material takes up landfill space, decom- poses and contributes to leachate generation. Through composting the yard waste, the organics can be returned to the soil to enhance soil tilth. Although the fertilizer value of this material is generally not considered to be significant, compost improves moisture holding capabilities, reduces soil compaction and improves production on compost treated soils. YARD WASTE COMPOSTING The yard waste composting process has some potential negative environmental effects such as odors and organically contaminated runoff. The IDNR permit process, which requires that these facilities be sited, developed and operated to minimize the negative factors and the potential benefits from use of the compost make the technology environmentally beneficial overall. MIXED SOLID WASTE COMPOSTING To meet the year 2000 waste reduction goal, it is recommended that Dubuque County consider composting mixed solid waste. This method has potentially negative environmental effects from leachate contamination of surface and groundwater and the production of odors. Processing under controlled con- ditions, however, will alleviate these problems. The stabilized compost can be used as a soil conditioner or possibly landfill cover. 11.2 LANDFILLING The final step in the hierarchy is landfilling, which is becoming more regulated due to environmental concerns. This technology will continue to be a necessary part of the overall waste management program and the tighter restrictions , including the Solid Waste Management Plans Part I and Part II, on landfill operations will result in improved environmental factors for this technology. In general, it is intended that implementing the Comprehensive Plan will be an overall environmental benefit. The intent of the legislation appears directed at environmental enhancement, and the hierarchy establishes the steps in solid waste management, in part, based on environmental factors. The success of implementing the Comprehensive Plan and the resulting envi- ronmental improvements will, however, depend on the public education and awareness program to convince the waste generators of the benefits, solicit their support and justify the costs of implementation of the Comprehensive Plan.
