Chalmers, Jr. PE RE: Proposal for Limited Phase II Subsurface Investigation Washington Road at Boy Scout Road Road Improvements Washington Road and Boy Scout Road Augusta, Richmond County, Georgia Gallet Proposal #: 03EOI07 Dear Mr. Chalmers: Gallet & Associates Inc. (Gallet) appreciates the opportunity to submit this proposal and cost estimate for your review. This proposal has been prepared to provide a Limited Phase II Investigation on the property referenced above in response to your request-for-proposal. Gallet performed a Phase I Environmental Site Assessment (ESA) for the proposed road improvements (road widenings) along Washington Road, Boy Scout Road, and Center West Parkway, near the intersection of Washington Road and Boy Scout Road, in Augusta, Richmond County, Georgia (report dated December 18, 2002). According to this Phase I ESA, a review of specific environmental regulatory listings indicated a facility that would potentially present an environmental threat to the subject site. The facility is located east- northeast of the subject site along Washington Road, and is listed in the Georgia Environmental Protection Division (GA EPD) Leaking Underground Storage Tank (LUST) database as follows: GA-069 (Crown Central Petroleum) 2851 Washington Road Augusta, Georgia 30909 EDR ill No: U003003224 Distance/Location: 647 ftJEast-northeast According to the Environmental Data Resources, Inc. (EDR) records review and the GA EPD, a confirmed release of a petrolewn product was reported on February 24, 1994 at the GA-069 (Crown Central Petrolewn) facility. The facility is currently under a corrective action plan (CAP-B), and a progress report was expected at the GA EPD at the end of December 2002. However, no further information was available at the time the Phase I ESA was completed. In addition, due to the topography at the facility, the groundwater is expected to flow in a westerly and southwesterly direction (towards the subject site). Based on the lack of information available on the regulatory status of the GA-069 facility, the prevailing groundwater flow, and the close proximity of the facility to the subject site, the GA-069 (Crown Central Petroleum) facility is considered a recognized environmental condition in connection with the subject site. The purpose of this Limited Phase II Investigation will be to gather information regarding the possible presence of petrolewn constituents in the groundwater near the subject property. 1 Environmental Services.

Gallet will conduct a subsurface investigation to investigate on-site soil and groundwater quality. Four (4) borings will be advanced (near the eastern edge of the subject site) using Geoprobe™ technology, direct- push sampling methodology. The location of the borings will be determined in the field by the environmental professional. Groundwater sampling will be performed at each of the boring locations, to a maximum of 30 feet or until groundwater is encountered. 2. As a field indicator, soils will be screened using on-site headspace analysis of organic vapors by method of a photoionization detector (Pill). The screening process provides field data to help determine if soil has been impacted by petroleum from past site usage. 3. Groundwater samples will be collected and submitted to an accredited independent laboratory, for analysis of constituents related to on-site and off-site activities in accordance with Georgia EPD requirements. Parameters include: Volatiles including Benzene, Toluene, Ethylbenzene and Xylene (BTEX) using EPA Method 8260, and Semi-Volatiles including Polyaromatic Hydrocarbons (PARs) using EPA Method 8270. Upon completion of the fieldwork and laboratory analysis, an environmental assessment document will be prepared and will include fmdings, conclusions, and recommendations. COMPENSATION AND SCHEDULE We can complete the scope of services discussed above at a cost of: $ 4,370.00. Drilling Costs Laboratory Analytical Costs Field W ork/Report Preparation/Expenses Total: $ 1,500.00 $ 550.00 $ 2.320.00 $ 4,370.00 We are prepared to initiate the project immediately upon your written authorization to proceed. We anticipate the field program to commence within I week of written authorization. A verbal report of the analytical laboratory results will be provided within 1 week of field activities. Three copies of the final report will be submitted following our receipt of laboratory data. If another schedule is required, we are flexible to your specific needs. 2 Environmental Services' Geotechnical Services' Materials Testing Services 1341 Capital Circle. Suite L . Marietta.

We ask that you obtain permission from the owner for access and subsurface investigation. Also, because this investigation will entail advancing borings on the roadways or the roadway's righ-of-ways, we ask that you obtain permission from the appropriate government agency (i.e. Georgia Department of Transportation or the City of Augusta). CLOSING Thank you for considering Gallet for your environmental consulting services and allowing us to submit this proposal. We appreciate the opportunity to work with you as part of your TEAM and look forward to assisting you on this project.
