Afternoon Kyle, We had discussed closing out the current Nelson’s Cleaners TA during our last bi-weekly call. I believe everyone was in agreement that it would be the cleanest way to get this site back on track. We will submit a new proposal with current subcontractor quotes and new deliverable schedule. Please see the attached FDEP-approved WCD allowing for confirmation groundwater sampling based on the initial baseline sampling results. Although this WCD was approved, it doesn’t appear a TACO was ever generated. We completed the baseline sampling as scoped in Subtask 2, and we still owe you a GWMR, as I cannot see where we submitted it. The attached TACO leaves Subtask 2 intact (also adds in the referenced WCD confirmation GW sampling), and reduces out Subtasks 3 through 5. Once the GWMR is submitted, we can close out this TA. Let me know if you want to talk through this.

Steve.
