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: Nitrogen, ammonia total [as N] (11), Phosphorus, total [as P] (4).
Reports are due about 28 days after each monitoring period ends (the most common figure among MD permits in EPA's filings — check your permit).
