The Small Municipal Separate Storm Sewer System (MS4) General Permit sets the performance standards for six minimum control measures (MCMs). These standards are to reduce the amount of pollutants found in stormwater runoff as much as possible. Instead of creating another organization for stormwater compliance, the Hamilton County Storm Water District (District) operates through a group of existing County agencies (i.e., Partner Agencies). Staff at these agencies perform their agency work but also work on behalf of the district, using their specialized capabilities and/or legal authorities. 

The District is administered by Hamilton County Engineer’s Office (HCEO) and works with Partner Agencies, including Hamilton County Public Health (HCPH), Hamilton County Conservation District (HCCD), and Hamilton County Planning and Development (HCPD), to carry out permit compliance activities related to stormwater quality.
