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.
This permit expired on 2024-11-30 and is administratively continued: its last limits keep applying until a new permit is issued, and EPA still expects the reports.
Last period with anything received: 2026-07-31. Most often over: pH (8), BOD, 5-day, 20 deg. C (7), BOD, 5-day, percent removal (6).
Reports are due about 29 days after each monitoring period ends (read off this permit's own late-day counts in EPA's filings).
