Proposed Rule Change
Summary: EPA is proposing the 2020 Multi-Sector General Permit (MSGP) for stormwater discharges associated with industrial activity.

The proposed revisions include streamlined and more simplified language; revisions to permit eligibility and authorization-related provisions, including eligibility for stormwater discharges to Federal CERCLA sites, eligibility relayed to application of coal-tar sealcoat, and discharge authorization related to enforcement actions; the addition of requirements for public signage of permit coverage; the addition of requirements for operators to consider implementing major storm control measure enhancements; revisions to the monitoring requirements for universal benchmark monitoring and impaired waters monitoring; updates to benchmark values and new sector-specific benchmark monitoring; new additional implementation measures (AIM) that are triggered by benchmark monitoring exceedances; and revisions to sector-specific fact sheets.
