" ~~ Oc~~ . ~/q/crO The 12,000-gallon UST was removed fyom the Site on September 2, 1999. Follow-up environmental assessment at the tank location, as required by Federal and State UST regulations, confimled presence of soil .& groundwater contamination and warranted Corrective Action at the Site. However, the site is already under Corrective Action to address 1993 diesel fuel release. Therefore, an approach was adopted that will address recently observed contaminatiqn and, 1993 diesel fuel release contamination under one Corrective Action. A comprehensive summary of environmental site assessment and remedial activities were prepared by Environmental Management Associates on behalf of Augusta-Richmond County and sybmitted to Georgia Environmental Prote<;t~<?n Division on February 3, 2000. As a Corrective Action, we propose to continue existing Con-ective Action Plan of Monitoring Only (no active remedial actiqn). Under Monitoring Only Plan, we proposes two years of semiannual monitoring of groundwater at existing selective groundwater monitoring points to evaluate the effectiveness of natural attenuation on the groundwater contamination. Semiannual monitoring will be perfonned during the months of June 2000, December 2000, June 2001 and December 2001. Proposed Corrective Action is the cost-effective plan to_comply with Federal and State UST regulations. Change Order 1 will cover the cost to complete the activities proposed under Corrective Action Plan. Environmental Management Associates (EMA) is perf011l1ing ongoing Correction Action activities. Therefore, EMA was contacted to submit a proposal to complete the proposed additional activities. EMA personnel past involvement to address the groundwater quality assessment issues at the Raw Water Pumping Station Facility and interaction with the EPD on our behalf will help to address EPD concel1lS (if any) with regard to residual contamination and also keep the proposed work cost minimum. c, '. ..

Augusta.-Richmond County 530 Greene Street, Room 701 Augusta, Georgia 30911 Dear Mr.. Malik: Re: Request for Proposal Raw Water PumpingStation .. Augusta, Georgia EPD Facility 1.0. No. 9121080 Pursuantto Our recent conversation, Environmental Management Associates (EMA) is pleased to submit the following cost estimate to complete the proposed semiannual groundwater sampling and reporting requirements for the above referenced facility. In accordance with the report entitled "Summary of Analytical Results" dated February 3, 2000, EMA will complete the semiannual groundwater monitoring activities in June and December 2000 and 2001. The semiannual groundwater monitoring events will consist of the sampling of two existing monitoring wells (CRAMW-1 and CRAMW-2) and an additional monitoring well (MW-4) f<>r benzene, toluene, ethylbenzene,and xylenes (BTEX) and polynuclear aromatic hydrocarbons (P AH). To demonstrate that natural attenuation is occurring, EMA also recommends that these wells be measured in the field for dissolve~ oxygen (D.O.), oxidation/reduction potential, and pH. Monitoring well MW-4 will be used to monitor the backgrowld concentrations of the target and geochemical parameters. The result5 of the sampling and analysis events will be reported to EPD and Augusta- Richmond County in a semiannual groundwater monitoring report. The reports will be submitted:,in July 2000 and 2001 and January 2001 and 2002. The reports will include a brief summary i)f the Facility background, astj.mmary of findings that will include tabulated data and a pot~rtiometric surface map,a site ranking, and an evaluation to determine if a CAP-Part B will be r(~quired for this Facility or if the Facility qualifies for a "No Further Action" status. Based on the Scope of Work described above, EMA's estimated annual cqst to complete these activities'is $3,350 ($1,675 per event). The costs for two years would be $6,700.
