NPDES permit RI0100005 · Major POTW · effective, expires 2028-03-31 · 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: 2026-08-31. Most often over: pH (2), Flow, in conduit or thru treatment plant (1), Chlorine, total residual (1).
Reports are due about 15 days after each monitoring period ends (the most common figure among RI permits in EPA's filings — check your permit).
