NPDES permit TX0006025 · Major NON-POTW · administratively continued, expires 2023-06-20 · 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 2023-06-20 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: E. coli (3).
Reports are due about 20 days after each monitoring period ends (the most common figure among TX permits in EPA's filings — check your permit).
