NPDES permit IA0042773 · Minor POTW · administratively continued, expires 2025-04-30 · EPA's file as of 2026-09-19
Check this month's numbers before you fileThis permit expired on 2025-04-30 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: 2026-08-31. Most often over: BOD, carbonaceous [5 day, 20 C] (9), Solids, total suspended (3), Nitrogen, ammonia total [as N] (2).
Reports are due about 15 days after each monitoring period ends (the most common figure among IA permits in EPA's filings — check your permit).
