PUBLIC NOTICE OF MODIFICATION OF THE SALT LAKE CITY INDIVIDUAL
MUNICIPAL SEPARATE STORM SEWER SYSTEM PERMIT
PURPOSE OF PUBLIC NOTICE
The purpose of this public notice is to declare the state of Utah's intention to modify a Utah Pollutant Discharge Elimination System (UPDES) permit under authority of the Utah Water Quality Act, Section 19-5-104 and 107, Utah Code Annotated 1953, as amended. Said 'permit' refers to UPDES permit and the statement of basis, including the total maximum daily loads (TMDLs) if applicable, as per section 303 (d) of the Federal Clean Water Act (CWA).
PERMIT INFORMATION
PERMIT NAME: Salt Lake City Municipal Separate Storm Sewer System (MS4) UPDES Permit
PERMIT NO: UTS000002
BACKGROUND
The Federal Clean Water Act requires that storm water discharges from certain types of facilities be authorized under stormwater discharge Permits. (See 40 CFR 122.26.) The goal of the stormwater Permits program is to reduce the amount of pollutants entering streams, lakes and rivers as a result of runoff from residential, commercial and industrial areas. The original 1990 regulation (Phase I) covered municipal (i.e., publicly-owned) storm sewer systems for municipalities over 100,000 population. The regulation was expanded in 1999 to include smaller municipalities. This expansion of the program to include small MS4s is referred to as Phase II. Salt Lake City encompasses approximately 110 square miles within the lower Jordan River Basin and is comprised of a population in excess of 186,440. Salt Lake City is defined as a medium municipality (Utah Administrative Code 'UAC' R317-8- 1.6(7)) and is required to maintain a Utah Pollutant Discharge Elimination System (UPDES) storm water permit (UAC R317-8-11.3(1)(a)).
The State of Utah was granted primacy in the National Pollutant Discharge Elimination System (NPDES) program by USEPA in 1987. In Utah, storm water discharge Permits are issued by the Director. Utah's program is known as the Utah Pollutant Discharge Elimination System (UPDES) Program. The requirements of this Permit are intended to reduce the discharge of pollutants to the maximum extent practicable and meet water quality standards through the development and implementation of a Storm Water Management Program (SWMP).
This Permit serves as a modification of the previous Salt Lake City Municipal Separate Storm Sewer (MS4) Permit, UTS000002, issued June 22nd, 2021. This Permit is intended to cover new or existing discharges composed entirely of stormwater from the Salt Lake City metropolitan area, which is required by the State to obtain permit coverage.
This Permit Modification has significant changes in regard to the Special Conditions section. This section was updated to include requirements of MS4s under the Jordan River Watershed Wide Escherichia coli (E. coli) TMDL.
