Staff updates board on MS4 and CSGP draft changes from IDEM
Summary
Town staff reported on a stormwater conference summary: IDEM may shift post-construction requirements from the CSGP to the MS4 general permit; drafts are not public, and staff expect follow-up by year end.
Michael briefed the board on proposed regulatory changes discussed at a recent stormwater conference. He said IDEM presented draft changes that are not public yet but could change how local MS4s handle post-construction requirements; staff are gathering information and expect an update by the end of the year. "IDEM is considering removing post construction requirements from the CSGP and keeping the post construction requirements in the MS4 general permit," Michael said.
Staff noted a statutory constraint: Senate Enrolled Act 1037 requires MS4s not to be more stringent than IDEM, and members expressed concern that ambiguous or missing permit language could invite challenges if local MS4s attempt to preserve specific post-construction language. The board asked staff to monitor the rulemaking and report back when drafts become public.
