From: Walker, Gerry <Gerry.Walker@tetratech.com> Sent: Monday, April 27, 2020 1:51 PM To: Shirah, Ginger K Cc: Hicks, Richard Subject: FDEP contract HW560 Task Assignment CSS-26A schedule extension request Fosgate Road Dump site

Ginger, Tetra Tech would like to request a schedule extension for FDEP contract HW560 Task Assignment CSS‐26A the Fosgate Road Dump/Montverde Geophysics site in Montverde Fl. The extension request is for the Task 2 deliverable of Field notes, lab shipment receipts, chain of custody, and photographic log from private well sampling activities originally scheduled for April 20, 2020 and the overall Period of Performance end date of April 30, 2020.

The original project’s scope of work was sample private residential wells near the site and for FDEP to send letters to homeowners in the targeted area requesting permission to sample their wells and notifying homeowners of Tetra Tech’s role in the project and field schedule. The field effort would have required Tetra Tech’s employees go door‐to‐door and interact with local residents to sign access forms and sample the wells. Because of the Covid‐19 pandemic, we had concerns that the door‐to‐door interaction would put both the employees and the residents at risk to exposure and wanted to delay the project. However since then, FDEP has been able to obtain resident’s signed access forms and therefore direct person‐to‐person interaction with the residents is not required. However the project was delayed in obtaining the signed access forms. In addition, the original field work was scheduled for the week of April 6, 2020 in order to meet the EPA laboratory schedule. However the EPA laboratory indicated they had capacity issues, so they requested that we postpone the Fosgate sampling until the week of May 18, 2020.

Therefore Tetra Tech requests a schedule extension of the Task Assignment CSS‐26A Task 2 deliverable to June 12, 2020 and the POP end date to June 30, 2020.

Please let me know if you have any questions or need additional Information. Thank you.
