Dear NCR WQCB,
Here is Point Arena's report for the month of December 2024. The plant was in compliance with Il discharge requirements. We were only able to submit three of four samples to the Lab, due t oad flooding and the Holiday's. During this month we have maintained the required freeboard at all times, in all of our percolation ponds.
There were no blockages or overflows in the collection system during the month of December 2024.
under my direction in accordance with a system designed to assure that qualified personnel roperly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system or those persons directly responsible for gathering the information, the information submitted, is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, Respectfully,
Joseph C. Wilson
