Dear NCRWQCB,
Here is Point Arena's report for the month of June 2025. The plant wasn't in compliance with all discharge requirements. We exceeded our monthly average of 50mg/l, we ended up with
99.5mg/l. 49.5mg/l over our limit. Algae is the problem with our TSS, which happens every year at this time. We have sprayed both lagoons and have added Lyme for control. We sprayed Argo's again to kill the Algae. We are hoping this time will do the trick. So far it's been a struggle. Feel free to call if you have any questions. 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 June 2025.
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.
Respectfully,
