(MWH) appreciates the opportunity to submit this proposal to conduct a Risk -Based Corrective Action (RBCA) investigation and complete a Tier 2 Site Cleanup Report (SCR) for the City of Dubuque, Iowa (City) related to the former petroleum product underground storage tank (UST) at the City's water pollution control plant (WPCP) site. This proposal is intended to satisfy the Iowa Department of Natural Resources (IDNR) requirements, as outlined in their February 4, 2011 letter. MWH understands the Tier 2 SCR Report is due to the IDNR by May 31, 2013. The proposed activities are intended to compliment the previously collected data as outlined below. Task 1 — Fieldwork MWH will contract with and supervise an Iowa - licensed drilling company to advance, continuous sample, and install two 2 -inch diameter polyvinyl chloride (PVC) groundwater monitoring wells, and one 1 -inch diameter PVC soil vapor monitoring well hydraulically downgradient of the existing monitoring wells in an attempt to delineate the extent of petroleum hydrocarbons associated with the former UST. The groundwater monitoring wells will be installed at an approximate depth of 35 feet below grade, as determined in the field, and the soil vapor well will be installed at an approximate depth of 14 feet below grade. All soil samples collected for laboratory analysis will be placed in pre - cleaned 4 -ounce glass jars and stored in an iced cooler. The samples will be delivered under chain -of- custody (COC) documentation to Keystone Laboratories, Inc. (Keystone) in Newton, Iowa for analysis of benzene, toluene, ethylbenzene, and xylenes (BTEX) and methyl tertiary butyl ether (MTBE) by Iowa Method OA -1. 11153 Aurora Avenue TEL 515 253 0830 Des Moines, IA 50322 -7904 FAX 515 253 9592 www.mwhglobal.com Mr. Steve Sampson Brown Page 2 August 27, 2012 Existing and newly installed wells will be measured and surveyed using a level and rod to obtain horizontal control and vertical elevation control. Soil cuttings recovered from drilling activities are planned to be thin - spread on site in a location approved by the client. Existing and newly - installed groundwater monitoring wells will be gauged to measure the static water level using an electronic interface probe. A groundwater flow direction map will be constructed based on the water table data. Monitoring wells will be purged and sampled using disposable bailers. Groundwater samples will be placed in 40- mililiter glass vials preserved with hydrochloric acid and stored in an iced cooler. The samples will be delivered under COC to Keystone for analysis of benzene, toluene, ethylbenzene, and xylenes (BTEX); and methyl tert- butyl ether (MTBE) by Iowa Method OA -1. A second mobilization event is budgeted with installation of two additional groundwater monitoring wells should laboratory results indicate further plume delineation is needed. The additional wells and mobilization will not be used unless they are necessary. A receptor survey will also be conducted to locate nearby receptors that could be a risk from the petroleum hydrocarbon release. Receptors include sanitary and potable water lines, basements, and drinking or non - drinking water wells. As much information as possible regarding the receptors will be obtained from previous site investigation activities, City records, and other sources before mobilizing to the site. Task 2 — Reporting MWH will compile a Tier 2 Site Cleanup Report (SCR) using the existing and newly collected data. Additional information will be collected from the State of Iowa and City offices, as necessary. The Tier 2 SCR will be completed under the direction of an Iowa - Certified Groundwater Professional (CGP) and sent to the City for review and signature. Upon receiving approval and signature, the Tier 2 SCR will be submitted to the IDNR. Task 3 — Project Management This subtask includes project management time for project administration; communication with City representatives, subcontractors, MWH staff, and IDNR staff; and associated activities. ESTIMATED COSTS The tasks will be completed on a time - and - materials basis in accordance with the October 18, 2010 Consulting Services Agreement (CSA) and MWH's current "Fee Schedule," attached. The Mr. Steve Sampson Brown Page 3 August 27, 2012 estimated cost to complete the tasks identified above is approximately $26,550, as indicated in the following table: MWH Services Subcontractors Task and Expenses (Driller & Lab) Total 1 — Fieldwork $ 8,050 $ 11,900 $ 19,950 2 — Reporting $4,900 - $ 4,900 3 — Project Management $ 1,700 $ 1,700 Subtotal $ 14,650 $ 11,900 Project Total $ 26,550 If you concur with the scope of services and associated budget, please sign both copies of this proposal and return one copy as our authorization to proceed.
