Town of Carefree Stormwater Management Plan
This Stormwater Management Plan (also referred to as a Stormwater Management Program [SWMP]) has been prepared by the Town of Carefree (Town) as required by the Arizona Department of Environmental Quality’s (ADEQ) Arizona Pollutant Discharge Elimination System (AZPDES) General Permit Number AZG2016-002 (Permit). The Permit was issued on September 29, 2016 and became effective on September 30, 2016.
This SWMP describes the policies and procedures the Town will implement to reduce, to the maximum extent practicable (MEP), pollutant discharges to and from the small municipal separate storm sewer system (MS4). The overall goal of the program is to ensure to the MEP that discharges from the MS4 do not cause or contribute to exceedances of surface water quality standards.
As required by the Permit, the SWMP addresses the six minimum control measures (MCMs):
1. Public Education and Outreach
2. Public Involvement and Participation
3. Illicit Discharge Detection and Elimination Program
4. Construction Activity Stormwater Runoff Control
5. Post-Construction Stormwater Management in New Development and Redevelopment
6. Pollution Prevention and Good Housekeeping for Municipal Operations
The SWMP is designed to be a comprehensive program document outlining how the stormwater program is implemented and maintained; therefore, additional sections have been added to describe other Permit-required support activities, including Analytical Monitoring, SWMP Evaluation and Revision, Reporting, and Signatory Requirements.
The SWMP describes the best management practices (BMPs) the Town implements and also describes the overall planned approach to stormwater pollution prevention. This SWMP addresses the requirements of the Permit and reflects the needs and constraints of the Town.
The SWMP complies with the requirements specified in Code of Federal Regulations (CFR) Chapter 40 Part 122.32, incorporated by reference in Arizona Administrative Code (AAC) R18-9-A902 and A905. The SWMP has been prepared to meet the requirements identified in the Permit and is certified according to Permit Section 9.9.
