Check this month's numbers before you fileThis permit expired on 2020-04-30 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: Nitrogen, ammonia total [as N] (4), Chloride [as Cl] (2), Coliform, fecal general (1).
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).
