Proposed Scope of Work Imperial Cleaners Site Assessment and Reporting Task Assignment DC013B TACO #1 1500 E. Commercial Blvd, Oakland Park, Broward County, FL ERIC_4106 (Former Facility No. 069500959) Aptim Environmental & Infrastructure, LLC March 6, 2023

The following is the proposed scope of work for DC013B Task Assignment Change Order (TACO) #1 for the former Imperial Cleaners site located in Oakland Park, Broward County, Florida. The proposed scope of work under Task Assignment DC013B TACO #1 is to resolve Work Change Directives 1 through 4, previously approved for the site.

Subtask 3 Soil & GW Field Activities

WCD #1 was approved for the analysis of three (3) 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 $384.00, but is being resolved for a total of $256.00, as a laboratory error resulted in one sample not being extracted and analyzed.

WCD #2 was approved for the analysis of four (4) 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 $512.00 and is being resolved for that amount.

WCD #3 was approved to allow for additional time for the collection of the proposed soil samples. One additional day of sampling was required due to the thickness of the building slab and required extensive time to core and the subsurface sample collection which was problematic due to rocks and debris encountered below the slab. The WCD included mobilization, labor, hotel, vehicles, and equipment required for the additional day of soil assessment activities. WCD #3 was approved for a total of $3,172.43 and is being resolved for a total of $3,172.42, due to rounding on the spreadsheet.

WCD #4 was approved for the analysis of four (4) 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 $256.00 and is being resolved for that amount.

As previously discussed, the Imperial Cleaners property changed ownership while our field personnel were onsite performing the soil assessment and the work was required to be rescheduled upon execution of an updated agreement. The remaining soil samples were only recently collected.

Currently the Direct Push groundwater sampling event is scheduled for March 20 through 22, 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.
