Re: Proposal for Well Abandonment

Williamsburg Dry Cleaner (former) 5458 Central Florida Parkway Orlando, Florida Facility ID ERIC_5031

Dear Mr. Talley:

Professional Service Industries, Inc. (PSI) is pleased to provide this proposal to complete the well abandonment activities for the referenced location. Included with this proposal is a brief discussion of the project history, proposed scope of work, cost estimate, and a proposed schedule for completion.

PROJECT BACKGROUND

The former Williamsburg Dry Cleaners occupies a tenant space near the western end of the “Williamsburg Downs” Shopping Center. The facility is currently doing business as “All Star Dry Cleaners” with on-site cleaning using the petroleum product DF-2000. The possible solvent release was identified through a Site Screening Investigation completed by Nelson Engineering in June 1997. A Site Assessment Report was submitted by Chastain-Skillman (CS) in April 2015. The results of the assessment revealed a vadose zone source area under the south end of the tenant space and a dissolved plume extending from the building toward the south- south west. The SAR concluded with a recommendation to begin groundwater monitoring.

A Performance Base Cleanup (PBC) agreement to complete an Interim Source Removal by Soil Vapor Extraction was tasked on July 19, 2016. The SVE system was made operational on December 9, 2016 and performed as designed through August 2018. The last Remedial Action System Status Report dated August 31, 2018, concluded that the PBC goals had been met and that the system should be decommissioned and removed from the site. Following FDEP approval, the SVE system was decommissioned, and the trailer was removed from the Site on September 14, 2018.

FDEP – Williamsburg Dry Cleaners

Post Active Remediation (PARM) groundwater monitoring was completed in October 2018 and October 2019. No VOH contaminant of concern concentrations exceeded GCTLs at any of the well locations that were sampled. The FDEP Memorandum dated August 7, 2020, recommended completion of two additional quarterly groundwater monitoring events, which were conducted in September and December 2020. The final PARM report with a Site Rehabilitation Completion request for No Further Action without Controls was approved by the Department on March 15, 2021, and the SRCO was issued on May 28, 2021.

The following proposal includes costs to properly plug and abandon the remaining remediation wells and monitoring wells at the site.

PROPOSED SCOPE OF WORK

The proposed well abandonment activities will be implemented in general accordance with the FDEP’s Standard Operating Procedures for Field Activities (DEP SOP-001/01) and the site Health and Safety Plan developed for this project. CS will conduct the following activities to address the project objectives:

Plugging Requirements for Williamsburg Dry Cleaners Facility ID number ERIC_5031

Well Diameter Depth 8 " MH in 2'x2' pad

4 " MH

in 6" boring Patch with: (inch) (feet)

MW1 1 8 X Concrete MW2 1 12 X Sand MW3 1 9 X Sand MW4 1 12 X Concrete MW5 1 12 X Sand MW6 1 12 X Sand MW7 1 24 X Sand MW8 1 24 X Concrete MW9 1 39 X Concrete

MW10 1 24 X Concrete MW11 0.75 24 X concrete

VE3 2 6 X Sand VE4 2 6 X Sand VE5 2 6 X Concrete VE6 2 6 X Concrete total linear feet 224 13 2

FDEP – Williamsburg Dry Cleaners

Subcontract a licensed drilling contract to properly abandon the wells listed in the above table. All of the surface completions and manholes will be removed, and the paving restored with a smooth concrete patch. Sand will be used to backfill the pad voids in grassed areas.

CS will provide field oversight, photographic documentation, and prepare a Well Abandonment Report as the final deliverable for this project.

COST ESTIMATE AND SCHEDULE

The cost estimate for the plugging activities is included on the attached cost spreadsheet and level of effort. All PSI services will be conducted in accordance with the terms and conditions contained within FDEP Bureau of Waste Cleanup Services Consolidated Contract No. HW552.

The anticipated schedule to complete these activities following authorization to proceed is as follows:

initiating field work within twenty-one (21) days, and provide the FDEP with the well abandonment report within 45 days.

PSI appreciates the opportunity to be of service to the FDEP. We look forward to working with you on this important project. If you have any questions, please feel free to contact us at (813) 886-1075.
