NPDES permit SC0001180 · Major NON-POTW · effective, expires 2030-12-31 · 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: 2026-07-31. Most often over: Solids, total suspended (3).
Reports are due about 29 days after each monitoring period ends (the most common figure among SC permits in EPA's filings — check your permit).
