DATE: June 20, 2022

SUBJECT: Negotiation Summary – CER21, Task Assignment Change Order #1TA CSS-01A Advanced Chemical Co. - ERIC_15071 Site Investigation (SI) Activities

This Task Assignment Change Order (TACO) is for changes in cost associated with an additional day of groundwater sampling activities for conducting Site Investigation activities at the Advanced Chemical Co property. The work was conducted at the former Advanced Chemical Co property at 301 Zell Drive Orlando, Orange County, Florida. The services are being conducted using federal funds from the CERCLA Site Screening Program (CSS) cooperative agreement that is administered by DEP on behalf of EPA.

Subtask 1 Project Management An Increase in labor expended increased the Project Management hours from 12.6 to 13.3 hours.

This resulted in an increase of $117.00.

Subtask 3 SI Activities TACO #1 Subtask 3 includes an additional day of groundwater sampling which was required due to the slow stabilization of the monitoring wells encountered during the initial day of sampling.

Specifically, the TACO includes labor, travel, equipment, and expendables for an additional day of groundwater sampling. The additional groundwater sampling resulted in an increase of 10 labor hours, costs in expendables, vehicle rental, and sampling equipment This resulted in an increased cost for this subtask of $1,349.90.

Summary DEP’s CSS Project Manager and Aptim’s Project Manager have both agreed to the above charges. All charges noted above represent a total overall cost increase of $1466.90. The final cost associated with this TA increased from $24,434.16 to $25901.06. Documentation of these costs is included in the attached TACO Request, the Delta LOE spreadsheet and the Cost Actual LOE spreadsheet, Work Change Directives #1, and the TACO Form for CSS01A prepared by the Department. The final deliverable for Subtask 3 – Field notes, MW installation logs, photos, GW sampling logs, soil sampling logs, COCs, and Well Abandonment has already been received.

Proposed Scope of Work Advanced Chemical Co. Inc.

Site Investigation and Reporting Task Assignment CSS01A TACO #1 ERIC_15071 (Former COM_148838) Aptim Environmental & Infrastructure, LLC June 8, 2022

The following Task Assignment Change Order (TACO) scope of work for the former Advanced Chemical Co. Inc. facility, located in Orlando, Orange County, Florida has been prepared to resolve Work Change Directive (WCD) #1, approved by the FDEP on May 19, 2022. WCD#1 was approved for additional labor and equipment to allow for an additional day of groundwater sampling.

Subtask 3: SSA Field Activities:

As noted above, TACO #1 Subtask 3 includes an additional day of groundwater sampling which was required due to the slow stabilization of the monitoring wells encountered during the initial day of sampling. Specifically, the TACO includes labor, travel, equipment, and expendables for an additional day of groundwater sampling. WCD #1 was approved for $1,500.00 and is resolved for a total of $1,466.90.

Field activities have been completed at this time. Therefore, and extension to the August 31, 2022 TA completion date should not be necessary.

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 contract number HW689. APTIM will begin the proposed scope of work upon issuance of the Task Assignment Notification.
