Indiana's Construction Stormwater General Permit (CSGP), which replaced the repealed Rule 5 (327 IAC 15-5) in December 2021, governs land disturbance across St. Joseph County. Any construction disturbing one acre or more must obtain CSGP coverage before work begins.
From South Bend and Mishawaka to unincorporated townships and the smaller towns of New Carlisle, Lakeville, North Liberty, and Walkerton, IDEM administers the Construction Stormwater General Permit alongside the county's MS4 stormwater program. A project disturbing one acre or more, or a smaller lot within a larger common plan of development, must file a Notice of Intent, prepare a Construction/Stormwater Pollution Prevention Plan, and pay the $175 fee before clearing land. Runoff eventually reaches the St. Joseph River, so post-construction controls must limit sediment and pollutants discharged to waters of the state. The local MS4 review authority verifies the plan meets CSGP standards.
Disturbing one acre or more without CSGP coverage violates the permit and Indiana water law, drawing stop-work orders, IDEM enforcement, mandatory drainage retrofits, and civil penalties until the site is stabilized.
