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: BOD, carbonaceous [5 day, 20 C] (9), BOD, 5-day, 20 deg. C (9).
Reports are due about 15 days after each monitoring period ends (read off this permit's own late-day counts in EPA's filings).
