Subject: Approval to Use the Seven New Evaporation Ponds
Dear Mr. Finlinson:
The Division of Water Quality (DWQ) conducted a final inspection on May 22, 2024 of the Seven New Evaporation Ponds.During the final inspection there was a pipe boot in cell 4 that needed
to be repaired. On June 3, 2024 DWQ received the documentation and photo that the repair had been completed and tested.
Each pond was evaluated individually and I paid particular attention to the placement, seaming and testing of the liners. This was completed over many months starting in October, 2023.
Based on the final inspection, the review of the pipe boot repair, and the review of each individual pond, DWQ approves the use of the Seven New Evaporation Ponds.
If you have any questions about this letter please contact me at [phone] or [e-mail].
Sincerely,
Woodrow W. Campbell, P.E.
