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: 2026-07-31. Most often over: Solids, total suspended (14), Nitrogen, ammonia total [as N] (5), BOD, 5-day, 20 deg. C (4).
Reports are due about 20 days after each monitoring period ends (the most common figure among OH permits in EPA's filings — check your permit).
