How is storm water regulated?

Since the enactment of the Federal Clean Water Act in 1972, the focus of efforts to control water pollution has continued to evolve.

The primary concern of the USWAC is the UPDES Phase I and Phase II Stormwater Regulations which came into effect in Utah state in 2003. Phase II regulates stormwater systems in smaller communities and construction projects larger than one acre or parcel under one acre that are part of a common development.

The Utah State Division of Water Quality is responsible for overseeing compliance with the UPDES Phase I and II Stormwater Regulation via Municipal Separate Storm Sewer System Permit (MS4 Permit).
