This permit expired on 2026-05-31 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: 2026-08-31. Most often over: Nitrogen, ammonia total [as N] (22), E. coli (21), BOD, carbonaceous [5 day, 20 C] (12).
Reports are due about 15 days after each monitoring period ends (the most common figure among TN permits in EPA's filings — check your permit).
