Check this month's numbers before you fileSign-ups are not open yet. We counted that someone asked — not who, and not which permit — and we open them once enough people do. The check stays free.
Last period with anything received: 2026-08-31. Most often over: Carbon, tot organic [TOC] (2), BOD, 5-day, 20 deg. C (2), pH (1).
Reports are due about 28 days after each monitoring period ends (the most common figure among LA permits in EPA's filings — check your permit).
