This Task Assignment authorizes Golder to prepare an Interim Source Removal Work Plan in accordance with the October 4, 2022, Scope of Work, Cost Estimate, and Bid Documentation.

Subtask 1: Project Management An automatic calculation based upon total direct labor hours determines the labor hours within this subtask.

Subtask 2: Interim Source Removal Work Plan This subtask includes labor hours for Golder to contact and meet with property owner and develop/prepare a draft Interim Source Removal Work Plan for soil excavation and enhanced bioremediation application. Golder will submit the ISR Work Plan as the deliverable to FDEP.

The Work Plan will include a summary of the previous site assessment activities completed at the site; the horizontal and vertical extent of the proposed ISR activities; The proposed pre-excavation activities, including coordination with the property owner, utility location services, a well abandonment or protection plan, erosion control measures, a site security plan, permitting, and documentation of pre-excavation site conditions; the proposed soil excavation and waste management procedures; the proposed bio and/or chemical amendment and dosage to be added to the base of the excavation area prior to backfill, including an Underground Injection Control (UIC) Notice and a UIC Monitoring Plan; the proposed backfill and site restoration activities; and health and safety considerations, including recommended personal protective equipment and dust/vapor control measures.

Golder and the FDEP confirmed on October 10, 2022, that an Access Agreement with the current real property owner of the Dixie Cleaners (ERIC_4531) site has been executed.

The FDEP Project Manager agrees to the scope of work and final cost associated with this Task Assignment. The final cost for this Task Assignment is $7,419.51 with 40 labor hours.

RE: COST PROPOSAL FOR LAKESHORE PLAZA – DIXIE CLEANERS

INTERIM SOURCE REMOVAL WORK PLAN

1931 BLANDING BOULEVARD

JACKSONVILLE, DUVAL COUNTY, FLORIDA

DEP FACILITY ID NUMBER: ERIC_4531

PROPOSED TASK ASSIGNMENT: HW685_DC027B

Dear Ms. Shirah:

Golder Associates USA Inc. (Golder) is pleased to provide the Florida Department of Environmental Protection (DEP) with this cost proposal to develop an Interim Source Removal (ISR) Work Plan for the above-referenced site.

This proposal includes a description of the proposed scope of services, level of effort sheets for each subtask, and a cost estimate form that summarizes the costs of the proposed services. The scope of work is based on the recommendations accepted by the DEP in the September 29, 2022, e-mail correspondence to Golder. The proposed scope of services is described below.

SUBTASK 1 – PROJECT MANAGEMENT

To facilitate project quality and satisfactory completion of the proposed scope of work, all aspects of this project will be overseen by an experienced project manager. The project manager will be responsible for the schedule, budget, invoicing, project activities, and communications with DEP and the field team. Project management will include coordination of field activities; resource allocation to confirm the work is conducted by qualified professionals in accordance with the project schedule; cost control and tracking of the budget status; and submittal of project invoices in accordance with DEP Waste Site Cleanup Section requirements. The project manager will oversee the work so that it is conducted in a manner that is consistent with the requirements of the DEP-approved task assignment.

SUBTASK 2 – INTERIM SOURCE REMOVAL WORK PLAN

Golder performed soil sampling activities in July and August 2022 to complete the delineation of chlorinated volatile organic compound (VOC) contamination in onsite soils. During the soil sampling activities, Golder identified cis-1,2-Dichloroethene (cis-1,2-DCE) in soil at concentrations above the Soil Cleanup Target Level (SCTL) for

Ms. Ginger Shirah Proposal No. 202208346

Florida Department of Environmental Protection October 4, 2022 leachability, based on groundwater criteria, at multiple locations. Subsequent VOC analysis using the Synthetic Precipitation Leaching Procedure reported cis-1,2-DCE concentrations above the Groundwater Cleanup Target Level. The September 2022 analytical results indicated that the horizontal extent of chlorinated VOC contamination at the site has been delineated. Golder recommended developing an ISR Work Plan to excavate the soil with chlorinated VOC concentrations present above the SCTL for leachability, and the DEP agreed. The proposed excavation layout, based on the soil sampling results, is shown on the attached Figure 2.

The ISR Work Plan will include the following:

▪ A summary of the previous site assessment activities completed at the site.

▪ The horizontal and vertical extent of the proposed ISR activities.

▪ The proposed pre-excavation activities, including coordination with the property owner, utility location services, a well abandonment or protection plan, erosion control measures, a site security plan, permitting, and documentation of pre-excavation site conditions.

▪ The proposed soil excavation and waste management procedures.

▪ The proposed bio and/or chemical amendment and dosage to be added to the base of the excavation area prior to backfill, including an Underground Injection Control (UIC) Notice and a UIC Monitoring Plan.

▪ The proposed backfill and site restoration activities.

▪ Health and safety considerations, including recommended personal protective equipment and dust/vapor control measures.

▪ A Remedial Action Plan Checklist.

▪ An estimated cost and schedule to implement the ISR Work Plan.

COST AND SCHEDULE

The estimated cost to complete the proposed scope of work is $7,419.51. The LOE/CEF sheets are included in Attachment A. The following table summarizes the proposed costs and deliverable schedule.

Task Proposed Cost Proposed Schedule/Deliverables

Subtask 1 – Project Management $ 844.37 December 21, 2022

Subtask 2 – ISR Work Plan $ 6,575.14 November 22, 2022 (ISR Work Plan)

Total/Completion Date $ 7,419.51 January 31, 2023

Please be aware that Golder has been acquired by and is now a Member of the WSP family of companies. Golder remains as a legal entity and is the proposed contracting entity for this proposal. We are in the process of integrating the resources of our companies. Correspondence for this proposal should continue to be addressed to the undersigned.
