6C(2) Proposal for Supplemental Phase II Assessment

Risk Integrated System of Closure (RISC) Default Closure Values for Residential and Industrial /Commercial Properties. Upon completion of the initial data review, a "Letter Report" will be prepared which presents the sample collection and analytical methodologies used during the field phase of the assessment. Copies of the sample location maps, tabulated data and comparison to RISC Default Closure Values will also be incorporated. Recommendations for any additional assessment activities will be made for review and comment. SCHEDULE PES proposes to commence site investigation activities within one week of receipt of notification to proceed (depending on weather, utility clearance and Geoprobe availability). Upon mobilization, we anticipate completion of the Geoprobe sampling requiring one day. Laboratory analyses will be completed by Pace Analytical on standard one -week turnaround from receipt by the laboratory. Our initial discussion of results will occur within one day of receipt of laboratory analytical results. Our written "Summary Letter Report" will be submitted within one -week of the initial conference. COST ESTIMATE An ESTIMATED COST for Phase II Environmental Assessment Services with respect to the Baseline Environmental Assessment is presented as follows: Field Engineering Services /Project Management $ 900 Geoprobe Rental (assumes 1 -day @ $1,400 /day, including mobilization) $1,400 Equipment Rental and Expendable Sampling Supplies $ 300 Laboratory Analysis: 10 soil samples for % Moisture @ $10 /sample $ 100 10 soil samples for analysis of VOCs @ $85 /sample $ 850 5 groundwater samples for analysis of VOCs @ $85 /sample $ 425 Terra Core Sampling Kits for collection of soil samples (20 kits @ $15 /kit) $ 300 Reporting 900 ESTIMATED COST $5,175 Please note that this ESTIMATED COST should be considered a Project Maximum, which PES will not exceed without prior approval. However, should the scope of services require modification (i.e., additional borings) based upon field conditions and /or circumstances that would not have otherwise been anticipated, PES will notify the client of such "changed conditions" and resultant cost implication to the project. LIMITATIONS /QUALIFICATIONS The sampling and testing of soil, groundwater and /or other materials not specifically identified in this proposal is beyond the scope of services for this project. Cost estimates for our proposed services have been prepared based on the following assumptions: • PES will have unlimited access to the site during daylight hours; • Interior areas identified for borehole installations will be cleared to allow for sufficient access for equipment • No subsurface obstructions (buried utilities or fill debris) will interfere with our work; • Sufficient access /clearance will be provided for exterior Geoprobe locations; • Groundwater will be encountered within 30 -feet of ground surface; • Inclement weather will not interfere with the completion of our field work;
