Sign Campaign To Raise Awareness

In conjunction with the Michiana Stormwater Partnership (MSP), the City of Mishawaka placed signs near all major surface water bodies in the City limits. The signs include the MSP logo, waterbody's name, and the slogan "A Resource Worth Protecting." The signs also alert residents to the abundant surface water bodies in the area, and serve as a reminder to keep these vulnerable resources clean and free of pollutants. For more information, see the MSP Press Release (8/21/14).

Water Quality and the St. Joseph River

The St. Joseph River is a major waterway, its course winding for more than 200 miles in northern Indiana and southern Michigan before emptying into Lake Michigan. Polluted runoff from urbanized areas, agriculture, forestry, and construction causes physical changes to the river’s channel, harms fish and wildlife populations, kills native vegetation, fouls drinking water supplies, and can impair recreational uses.

Municipal Separate Storm Sewer System (MS4)

Storm sewers collect surface water runoff and convey these flows directly to the river without treatment. Pollutants picked up as runoff enter the Municipal Separate Storm Sewer System (MS4) causing serious water quality problems. The MS4 program is designed to minimize discharge of pollutants to the storm sewer system.

Protection under the Clean Water Act (1972)

The Clean Water Act of 1972, administered by the United States Environmental Protection Agency (USEPA), was implemented to protect our nation’s water supply. As part of this effort to protect and maintain water quality, the EPA established the Municipal Separate Storm Sewer System Program, known as MS4. Both the City of Mishawaka and Bethel College have been designated MS4 entities and must comply with the MS4 program requirements. Mishawaka and Bethel have partnered as co-permittees under the MS4 program, sharing responsibilities for program implementation.

Mishawaka Department of Planning

To initiate review of the Erosion and Sediment Control Plan for parcels one acre and greater, please submit complete plan to the Department of Planning in duplicate. An Erosion Control Plan (or Stormwater Pollution Prevention Plan (SWPPP)) is required to comply with City of Mishawaka Erosion Control Ordinance 5085 and the new IDEM Construction Stormwater General Permit (CSGP). As of December 18, 2021, Indiana no longer administers the construction stormwater program under Indiana Administrative Code (327 IAC 15-5 or Rule 5).

Requirements for SWPPP development and content are listed in CSGP Section 4.0, specifically 4.1, and at Guidance for Construction / SWPPP Development. When preparing a SWPPP, please use new IDEM document CSGP Construction/SWPPP Development Guidance (3-8-22). Other helpful IDEM storm water permitting links include Construction Plan Submittal and Review, Construction / Land Disturbance Permitting, and Step by Step Process for Compliance with the CSGP.

In addition to the SWPPP, a Notice of Intent (NOI) must be submitted to the IDEM via the IDEM Regulatory ePortal. Guidance on ePortal use can be found at Regulatory ePortal Guidance for Construction Stormwater Online. In order to complete the NOI submittal process, an applicant must attach an SWPPP Technical Review Form showing that the City of Mishawaka has reviewed and approved the SWPPP.
