NPDES permit ND0023370 · Major POTW · effective, expires 2031-06-30 · 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.
Last period with anything received: 2026-07-31. Most often over: Chlorine, total residual (6), pH (2).
Reports are due about 28 days after each monitoring period ends (read off this permit's own late-day counts in EPA's filings).
