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.

Reports are due about 25 days after each monitoring period ends (the most common figure among IL permits in EPA's filings — check your permit).
