Hi Kelly:

Attached please find a du date extension request for the subject site.

The 95% UCL report was completed for my review prior to the due date; however, I have asked for revisions. I appreciate your patience with this request.

Thanks, Teresa

Hi Kelly:

Please find attached Geosyntec’s revised proposed level of effort (LOE) to calculate a 95% Upper Confidence Limit (UCL) for Paynes Prairie Preserve State Park (PPPSP, Site ID No. 60SL-1) Area of Concern (AOC) 2 located in Alachua County, Florida. Geosyntec’s revised proposed work plan is described below and omits the development of a AOC 2 specific alternative soil cleanup target level and associated field activities. A deliverable schedule is also attached for grouped subtasks for invoicing.

Subtask 1: Project Management

Subtask 2: LOE Preparation – The LOE was developed based on guidance contained in Chapter 62- 780, Florida Administrative Code (FAC) and Chapter 62-777, FAC for conducting closure activities, including performing 95% UCL analyses.

Subtask 3: 95% UCL Calculation and Reporting – Geosyntec will perform “virtual remediation” to calculate an exposure unit-wide, 95% UCL of the arithmetic mean for arsenic so that site closure can be achieved under risk management option (RMO) III using institutional controls (on land use).

95% UCL will be calculated in accordance with Chapter 62-780.680(3)(b)1 FAC and pursuant to Appendix D in Chapter 62-777, FAC.

For the virtual remediation scenario, it will be assumed that locations “virtually removed” will be back-filled with soil verified to have an arsenic concentration below 2.1 milligrams per kilogram (mg/kg). The median method detection limit for arsenic will be used in the 95% UCL calculation as a surrogate concentration for locations assumed to have clean back-fill. The virtual remediation process will be performed iteratively to achieve unit-wide arsenic concentrations (95% UCL values) below the recreational A-SCTL previously established by the FDEP of 5.5 mg/kg. Soil sampling results and 95% UCL calculations will be provided in a letter report and submitted to FDEP. The letter report will include recommendations and a plan for closure of PPPSP AOC 2.

Geosyntec sincerely appreciates the opportunity to assist the FDEP with the closure of PPPSP AOC 2.

Please contact me with any questions.

Warmest Regards, Teresa
