Proposed Scope of Work Spot Busters Cleaners Site Assessment and Reporting Task Assignment DC011B TACO #1 6750 North State Road 7, Coconut Creek, Broward County, FL ERIC_4244 (Former Facility No. 069801109) Aptim Environmental & Infrastructure, LLC March 6, 2023

The following is the proposed scope of work for DC011B Task Assignment Change Order (TACO) #1 for the Spot Busters Cleaners site located in Coconut Creek, Broward County, Florida. The proposed scope of work under Task Assignment DC011B TACO #1 is to resolve Work Change Directives 1 through 3, previously approved for the site.

Subtask 3 Soil & GW Field Activities

WCD #1 was approved for the analysis of eleven (11) additional soil samples for SPLP extraction by EPA Method 1312 and analysis of the leachate for VOHs by EPA Method 8260. WCD #1 was approved for a total of $1,408.00 and is being resolved for that amount.

WCD #2 was approved for the analysis of six (6) additional soil samples for SPLP extraction by EPA Method 1312 and analysis of the leachate for VOHs by EPA Method 8260. WCD #2 was approved for a total of $768.00 and is being resolved for that amount.

WCD #3 was approved for the analysis of twenty-two (22) additional soil samples for SPLP extraction by EPA Method 1312 and analysis of the leachate for VOHs by EPA Method 8260. WCD #2 was approved for a total of $2,816.00, but is being resolved for a total of $1,792, due to the laboratory not completing eight (8) of the extractions within the laboratory method holding times. These eight samples were analyzed but a cost was not charged by the laboratory.

Currently the direct push groundwater sampling event is scheduled for March 13 through 16, 2023. The installation sampling of the subsequent monitoring wells, based on the direct push data should be performed in April. For that reason, a 90-day extension is requested to allow for time to access the adjacent property and complete the proposed scope of work. The 90-day extension would shift the remaining two deliverables to May 25, 2023 (Subtask 3) and June 29, 2023 (Subtasks 1, 4 and 5), respectively.

APTIM proposes to perform this scope of work in accordance with the terms and conditions of the contract executed between APTIM Environmental & Infrastructure, LLC and Florida Department of Environmental Protection No. HW689. APTIM will begin the proposed scope of work upon issuance of the Task Assignment Notification.
