The Small MS4 Annual Report is the guiding document for compliance with Arizona Department of Environmental Quality’s Municipal Separate Storm Sewer System (MS4) permit. This plan originates from the federal Clean Water Act legislation and details the steps the County takes to reduce the pollutants entering our rivers and washes.
A core component of the Maricopa Stormwater Management Plan (SWMP) are the 6 Minimum Control Measures (MCM’s) listed below:
MCM1: Public Education and Outreach
MCM2: Public Involvement
MCM3: Illicit Discharge Detection and Elimination
MCM6: Good Housekeeping
We would appreciate your input on the MCM’s, which will help us make future changes and improvements to better reflect our community and its needs.
