MCVM/j Attachment cc: Barry Lindahl, Corporation Counsel Tim Moerman, Assistant City Manager Michael Buelow, Environmental Stewardship Advisory Commission CITY OF DUBUQUE, IOWA MEMORANDUM January 27, 1999 TO: ~~c.v_~. City~"'r FROM: Michael Buelow, Chairperson, Environmental Stewardshi- dbAIZ. - Advisory Commission ~ ,/ SUBJECT: River Discovery Consortium Storm Sewer Stenciling Campaign Proposal Introduction The purpose of this memorandum is to recommend the consideration and approval of the Storm Sewer Stenciling proposal submitted to the Environmental Stewardship Advisory Commission by the River Discovery Consortium by the City Council. e Discussion The purpose of the Storm Sewer Stenciling Campaign is to educate our citizens on ways to protect our local watersheds, streams and river, by reducing the amount of toxic materials entering our storm sewer drains. These storm sewers empty into these streams and our Mississippi River. A stenciled or labeled message "Dump No Waste: Drains to River", or possibly" . . . Drains To Creek" or " . . . Drains To Basin", would be applied to selected storm sewer drains. This type of campaign has been successful in thousands of communities across the country. This pollution prevention message is an effective part of local community compliance with the federal Clean Water Act. The River Discovery Consortium is proposing this campaign as a public-private partnership with the Operations and Maintenance Department, which would share responsibility for planning, implementation, and enlisting volunteers. The Environmental Stewardship Advisory Commission recommends that the City Council consider this proposal for implementation, as an appropriate step in addressing the environmental stewardship objectives of both the 1996 Riverfront Plan and the Dubuque Comprehensive Plan. Action Step It is our recommendation that the attached Storm Sewer Stenciling Campaign proposal be submitted to the City Council for consideration and approval. e ATTACHMENTS e . e e STORM DRAIN LABELLING CAMPAIGN \VHA TIS NONPOINT SOURCE POLLUTION? Nonpoint source (NPS) pollution is caused when rainfall carries pollutants from a wide variety of sources into surface water or ground water. The term distinguishes pollution that is diffuse in its origins from pollution that is traceable to a single "point source,"like a factory or wastewater treatment plant. \VHAT ARE NONPOINT SOURCE POLLUTANTS? Many products and materials we use in daily life become nonpoint source pollutants when quantities of them reach bodies of water. NPS pollutants can be chemical, like pesticides and fertilizers. They can be automotive products like gasoline, motor oil, antifreeze and tire rubber. They might be common household items like paint and solvents. They can even be natural materials like soil, pet and animal manure, and grass clippings. HOW DO NPS POLLUTANTS REACH THE WATERSHED? Sometimes NPS pollutants wash directly into a creek, river or lake. Construction activity, when erosion control techniques are not utilized, sends soil anc~ debris directly into nearby creeks and streams. Agricultural activities also may generate NPS pollutants, when fertilizers, pesticides, livestock wastes and eroded soil are not managed properly and are allowed to wash directly into nearby surface waters. In urban areas, though, the most common route for NPS pollutants is the network of storm drains that carry excess rain water away from streets and directly into surface waters. NPS pollutants can be washed by rainfall from lawns, driveways and streets into storm drains, or they can be dumped there deliberately by people who are careless about the environment or who mistakenly think the storm drains flow to a water treatment plant. . HOW DO NPS POLLUTANTS AFFECT WATER QUALITY? Just as the nature ofNPS pollutants varies widely, so do their effects on water quality. Pesticides, antifreeze and motor oil contain toxic chemicals that are harmful to humans, animals and plants. Just one quart of motor oil can ruin the quality of 250,000 gallons of water. The phosphorous and nitrogen in fertilizers, pet and livestock wastes and decomposing leaves and grass can cause large amounts of algae to grow, which deplete the oxygen level in the water and can lead to fish kills. Animal wastes also introduce harmful "E-coli" bacteria and other pathogens into water supplies.. Sediment from soil erosion or construction activity can reduce the clarity of water, block sunlight needed by aquatic species and change the habitat. Litter and debris, particularly plastic items that e e e float, spoil the beauty of creeks, rivers and harbors and can be harmful to fish and birds who mistake them for food. WHAT IS STORM DRAIN LABELING AND \VHY IS IT NECESSARY? Many people mistakenly believe storm drain inlets empty to water treatment facilities, so they pour chemicals or sweep debris directly into storm drains. This dumping greatly increases the level of nonpoint source pollutants (leaves, soil, litter, fertilizers, pesticides, street residues) already present in urban storm water runoff and can contribute substantially to a decline in surface water quality. More communities are working to reduce nonpoint source pollution by labelling storm drain inlets with messages warniniCitizens not to dump polluting materials. As is the case with most drain labelling projects, we are recommending the Dubuque initiative be conducted by volunteer groups in 'cooperation with local authorities. The stencilled or labelled message along with the outline of an appropriate aquatic species, such as a catfish, will be determined by the location of the drains and into which component of the watershed they drain, thus we will select one of the following: "Dump No Waste, Drains To River", "Dump No Waste, Drains To Creek" and "Dump No Waste, Drains To Basin". These messages will remind would-be dumpers and passersby that the storm drains connect to local surface waters and that dumping pollutes those waters. In recent years, as states and local governments have learned more about how nonpoint I source pollution degrades water quality, storm drain labelling efforts have sprung up in communities across the country. The Center for Marine Conservation (CMC), a nationwide environmental organization dedicated to protecting marine life, estimates that 97 groups in 33 states and Canada now are involved in storm drain labelling. In 1992, the .CMC launched its "Million Points of Blight" campaign to educate people about the connection between storm drains and local waterways and to involve them in labelling efforts. * HOW DOES STORM DRAIN LABELLING ADDRESS CITY, STATE AND FEDERAL ENVIRONMENTAL POLICY? Storm Drain Labelling is an effective and direct means of advancing environmental objecitves stated in the city's 1996 Riverfront Plan and in the Dubuque Comprehensive Plan. In the Environmental Component of the Riverfront Plan, the Environmental Stewarship Advisory Commission called for "community education on river environment issues" and attention to the "habitats of all creatures of the Mississippi River bio-region which are greatly affected by any changes in their ecosystems." The Commission also proposed "monitoring of the Mississippi and the Dubuque waterway~ on the effects of watershed drainage". Storm Drain Labelling will serve as a catalyst for more comprehensive "monitoring" of the watershed and serve to expand our definition of that activity as not simply passive observation of the effluent, but also active prevention of toxic materials entering into the watershed 2 The Dubuque Comprehensive Plan asserts that "environmental quality goals must address the balance between responsible stewardship and protection of our environment and the impacts of urban living." Toward the accomplishment of these goals, the plan calls for the "development of ongoing environmental education programs for citizens of all ages, building on the community's natural resources." Furthermore, the plan states as an objective to "identify and develop potential controlling measures to safeguard water and air quality." The River Discovery Consortium intends to serve as a civic-action association which will initiate and implement directives ai!eady determined through the leadership of the Environmental Stewardship Commission and the City of Dubuque. In this regard, the storm drain labelling campaign can be seen as one link in a chain of collaborative civic partnerships which will successfully address water quality issues. This project also coalesces with Phase II of the federal Storm Water Act requiring municipalities with a population of 50,000 or more to reduce discharges to the "maximum extent practical" and to conduct public education relative to storm drains. These regulations will be out in final form in March of 1999 and permits will need to be inplace by May 2002. Furthermore, the designation of the Upper Mississippi River as an American Heritage River will increase federal resources available to our community to "attack pollution problems" and "protect watersheds." The sto~ drain labelling project constitutes a concrete response to that designation and signifies our local intention to protect a national resource and utilize federal support. . Finally, Iowa must fulfill its obligations under the federal Clean 'Vater Act to implement a planning process to protect our waters and set pollution limits for'our watershed. According to the Iowa Environmental Council, Iowa is "far behind all other states in setting water quality standards, monitoring, identifying impaired waters, and acting to restore them." Initiating this project will showcase the City of Dubuque as taking responsibility for our watershed and becoming a sustainable community into the 21st century. . RECRUTITING VOLUNTEERS The River Discovery Consortium and its participating members are prepared to coordinate the recruitment of volunteers. A variety of methods would be availble to us in reaching out to volunteers. The City of Dubuque could inform several civic groups through a description of the project in City Focus. While a specific plan for outreach is not yet determined, it is likely we will use channels such as the newspaper, community meetings and encourage word-of-mouth communications about the program. Already there is significant interest among volunteer groups and a preliminary list of organizations is enClosed with this packet. 3 e e e TRAINING VOLUNTEERS Before participating in a storm drain labelling project, volunteers need training in three areas: technique, safety and information tracking. For the purposes of this proposal, we will forgo a detailed description of the components of the training. The training will be conducted through coordination of the River Discovery Consortium and the oversight of the City's Operations and Maintenance Department. As is the case with any successful volunteer effort, this training will be coupled with proper recognition of the volunteers and commendation for their community service. ASSESSING THE EFFECTIVENESS OF STORM DRAIN LABELLING By raising public awareness of nonpoint source pollution, storm drain labelling programs should discourage practices that generate nonpoint source pollutants. As with any public education project, however, it is difficult to precisely measure the effect storm drain labelling programs have on human behavior. Nor is it easy to measure reductions in certain components of nonpoint source pollution, which by definition is diffuse in origin. Some cities attempt to assess the effectiveness of storm drain labelling programs by periodically examining water samples from targeted storm drain outfalls (places where storm drains empty into a body of water). If storm drains leading to a particular outfall have been labeled, and if the level of pollutants from that outfall declines over time, one can assume the labelling has had some deterrent effect. / The city.ofFort Worth plans to track pollutant levels at 600 storm drain outfalls over the next five years to determine whether storm drain labelling and other pollution prevention efforts have improved water qualtiy in local creeks. The city of PIano is now collecting baseline water quality data from targeted outfalls and will take periodic samples to measure program results in the future. Monitoring outfalls is time-consuming, and periodic testing for component NPS pollutants can be expensive. Some cities infer success from increases in the volume of used motor oil delivered to used-oil recycling centers. Others measure success in terms of how many drains are labelled and the number of requests received by volunteer groups to participate in the program. They can also take into consideration the number of cleanups conducted by the city as a result of reports made by volunteers. * Adapted in part from the Texas Natural Resource Conservation Commission, the East Central Iowa Council of Governments, Iowa Department of Natural Resources and the City of Cedar Rapids. 4 RIVER DISCOVERY CONSORTIUM Storm Drain Labelling Campaign MATERIALS LIST (revised 10/1/98) Materials Supplied by East Central Iowa Council On GQvemment (ECICOG): 30 orange cones ' 33-36 Vests 20 flags 10 wire brushes 10 broom/dust pans "'NOTE: It is likely double this amount of equipment will be necessary for efficiency.
