Terracon Proposal No. PHF257197

Dear Mr. Sostre:

Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this proposal to the Florida Department of Environmental Program (FDEP) Waste Cleanup Section to conduct

Supplemental Site Assessment for the Jay Lee Cleaners (ERIC_5542) facility located at 119

Railroad Avenue in Chipley, Washington County, Florida. The scope of work presented in this cost proposal is based on the recommendations provided in the Annual Groundwater

Monitoring Report dated and submitted to the FDEP/DSCP on July 9, 2025.

Scope of Services

◼ Field preparation, mobilize to site, oversee installation of one shallow well screened 10-ft to 25-ft bgs and one deep well screened 100-ft to 105-ft bgs. Soil samples will be collected from the proposed deep well starting at 85-ft bgs to boring terminus. Prepare and submit email summary report including Soil boring logs, Well

Construction/Development Logs, and Well Completion

Permits/Reports.

◼ Field preparation, mobilize to site, measure depth to groundwater of 11 shallow and deep monitoring wells, perform groundwater sampling and laboratory analysis of seven (7) shallow monitoring wells (MW002, MW003, MW004, MW006, MW009, MW017, New Shallow Well) and four (4) deep monitoring wells (MW012, MW013, and mailto:Gabriel.Sostre@FloridaDep.gov

MW024). Prepare and submit email summary report including monitoring well sampling logs, chain-of-custody, and laboratory analytical report.

◼ Coordinate IDW transport and disposal. Review data and prepare a Supplemental Site Assessment Report including summary of findings, updated tables, exhibits, associated field logs, conclusions, and recommendations sealed by a

Professional Geologist/Engineer.

See attached LOE for details

Schedule

Deliverable Supplemental Site Assessment Report within 20 business days following receipt of laboratory results.

Compensation

See attached CEF for details.

DELIVERABLES

Subtask 2

An Email Summary Report will serve as part of Subtask 2 Deliverable to be submitted to the

Department within 5 business days of receipt of Well Completion Reports from the selected drilling company. The Email Summary Report will include the soil boring log, well construction/development logs, and well completion permits/reports.

Subtask 3

An Email Groundwater Sampling Summary Report will serve as part of Subtask 3

Deliverable to be submitted to the Department within 5 business days of receipt of groundwater laboratory analytical data. The Email Summary Report will include updated tables, figures, and laboratory analytical data report. The site monitoring wells are located in downtown Chipley and within heavy vehicular traffic areas. Due to safety concerns, it is requested that two (2) people be allowed to gauge and sample the site monitoring wells during this Subtask.

Subtask 4

The Supplemental Site Assessment Report will serve as the Subtask 4 (Final Deliverable) and will detail and summarize the monitoring well installation activities, field observations, and results of monitoring well analysis and will include updates to the site’s historical data tables and updated exhibits of groundwater flow, and well concentrations. Conclusions and recommendations will include a summary of results and recommendations for future sampling or remedial activities should the results indicate the onsite plume is nearing eligibility for Risk Management Option (RMO) I or RMO III closure. Additionally, the Site

Assessment Report will provide a summary of the pickup, transport, and disposal of the investigative derived waste (IDW) including a copy of the Non-Hazardous Waste Manifest.

Re: Drum Disposal – Chlorinated Solvents

Mr. O’Neal:

The price for the transportation and disposal (T&D) of 55-gallon drums of non-hazardous soil and water impacted with chlorinated solvents is listed below:

Description Rate Unit

T&D – Non-Hazardous Soil Impacted with Chlorinated Solvents $110.00 Per Drum T&D – Non-Hazardous Water Impacted with Chlorinated Solvents $125.00 Per Drum

Please ensure that all drum lids are properly secured and that drums are on a level surface like the surrounding area (i.e., not on a pallet, etc.). A single False Mobilization fee will apply if our driver is not able to locate a drum on site or if we are unable to access the property due to a locked gate, etc. This quote is valid for 90 days.

Please contact me if you have any additional questions.
