NPDES permit CO0000906 · Minor NON-POTW · administratively continued, expires 2020-05-31 · EPA's file as of 2026-09-19
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 2020-05-31 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: none.
Reports are due about 28 days after each monitoring period ends (the most common figure among CO permits in EPA's filings — check your permit).
