Dear NCRWQCB,
Here is Point Arena's report for the month of March 2026. The plant was in compliance with all discharge requirements. 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 March 2026.
Soldani spring box has been dry, the month of March 2026. We will resume testing in the event we do get water in it.
I certify under penalty of law that this document and all attachments were prepared under my direction in accordance with a system designed to assure that qualified personnel properly 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, including the possibility of fine or imprisonment for knowing violations.
