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: Copper, total [as Cu] (1).
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).
