This work uses grant funds from the State & Tribal Response Program (SRP) Grant that is administered by DEP on behalf of EPA.

Subtask 1: Project Management This subtask is a percentage of the overall project fees and has been negotiated as a contract rate. It includes project management, overhead, general and administrative, fringe and other direct costs. The agreed upon cost of this subtask is $626.14.

Subtask 2: QAPP/Work Plan, and Health and Safety Plan In accordance with an EPA directive, this subtask includes the completion of a Quality Assurance Project Plan (QAPP)/Work Plan, a Health and Safety Plan (HASP). The QAPP/Work Plan will provide a brief summary of the scope of work, tables and figures showing the proposed sample locations, and laboratory and field quality assurance measures and procedures. The agreed upon cost of this subtask is $758.18.

Subtask 3: SSA Activities Under this subtask, Wood will collect groundwater samples from the seven existing monitoring wells (MW-1 through MW-7) at the site. Depth to water measurements will also be collected. The monitoring wells will be sampled and analyzed for volatile organic compounds (VOCs) (including MTBE) using the United States Environmental Protection Agency (USEPA) Method 8260, polynuclear aromatic hydrocarbons (PAHs) using USEPA Method 8270, total recoverable petroleum hydrocarbons (TRPHs) using the FL- PRO method and lead using USEPA Method 6010 by Advanced Environmental Laboratories (AEL) of Tallahassee, Florida. The agreed upon cost of this subtask is $4,663.34.

RE: Cost Proposal to Conduct Supplemental Site Assessment Activities

Former Colt’s Station Site Trenton, Gilchrist County, Florida FDEP FAC ID No: 21/8508484

Dear Justin, Wood Environment & Infrastructure Solutions, Inc., (Wood) is pleased to provide this cost proposal as requested to conduct additional assessment activities at the former Colt’s Station site. Please find attached the cost summary spreadsheets for the workplan and QAPP package for the above-referenced site. The Workplan/QAPP will include a history of the site, site background including previous assessments, a site location map and site map with proposed monitoring well locations.

Subtask 1: Project Management This subtask is for project management and includes a percentage of the overall project fees and has been negotiated as a contract rate.

Subtask 2: Supplemental Site Assessment (SSA) Cost Proposal This task covers the level of effort to prepare the QAPP and this cost proposal. The SSA QAPP Workplan will provide a summary of the scope of work and include tables and figures showing the proposed sample locations.

Subtask 3: SSA Activities Under this subtask, Wood will collect groundwater samples from the seven existing monitoring wells (MW-1 through MW-7) at the site. Depth to water measurements will also be collected.

The monitoring wells will be sampled and analyzed for volatile organic compounds (VOCs) (including MTBE) using the United States Environmental Protection Agency (USEPA) Method 8260, polynuclear aromatic hydrocarbons (PAHs) using USEPA Method 8270, total recoverable petroleum hydrocarbons (TRPHs) using the FL-PRO method and lead using USEPA Method 6010 by Advanced Environmental Laboratories (AEL) of Tallahassee, Florida.

Subtask 4: SSA Report Upon completion of the field activities and receipt of the analytical data, Wood will prepare a Supplemental Site Assessment Report Addendum for the site detailing the findings of the most recent SSA activities as described above including updated site figures and tables with historical and new data included for comparison purposes, as well as conclusions and recommendations for the site.

The total estimated cost for the proposed activities is $8,641.47. The supplemental site assessment activities can be conducted once a signed Task Assignment has been received. It is estimated to take one day for the groundwater sampling including round trip travel.

Please call to discuss if you have any questions.
