NPDES permit CO0038024 · Minor NON-POTW · administratively continued, expires 2012-09-30 · 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 2012-09-30 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: 2026-06-30. Most often over: LC50 Static Renewal 48Hr Acute Daphnia magna (4), LC50 Static Renewal 96Hr Acute Pimephales promelas (1).
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).
