Municipal Separate Storm Sewer System (MS4s) Permits:
UPDES Permits

A MS4 is defined as a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains). It also is used to describe the owner/operator of that system. Each MS4 has their own operator that is responsible for maintaining and controlling pollutants that enter their system. Here is a list of permitted MS4 Operators within the State of Utah: Utah Permitted MS4 Operator List

Any permitted MS4 operator is regulated under UPDES permits listed below. Depending on the entity type and implementation date, these MS4 permits are split into two categories: Individual or General. Individual permits have guidelines that are tailored to a specific MS4 Operator. General permits have standard guidelines that cover many MS4 Operators. In Utah, Individual MS4 Permittees include: Salt Lake City, Salt Lake County, and Utah Department of Transportation. Salt Lake County is covered under the Jordan Valley Municipalities Permit with many co-permittees. Small MS4 General permittees include: any Small MS4 Operator in Utah not covered under the other permits.

NeTMS4 Permit Management

Small MS4 Permit management has moved into NeTMS4, hosted through the EPA’s Central Data Exchange (CDX) platform. Small MS4 Permittees will manage their permits and submit annual reports through NeTMS4 beginning in 2024.

See below for help files and presentations that include useful information for setting up and managing your account in CDX.

  • Helpful Resources
    • Permittees who are managing their permits in NeTMS4 should follow the EPA’s training presentation slides below, as it contains crucial information regarding how to set up your account in NeTMS4, and how to gain access to your permit. You may also gain access to a recording of this presentation by contacting Jake Nguyen at Nguyen.Jake@epa.gov.
    • If you need help creating an account in CDX, then you should follow the help file below to create your account.
    • If you already have an account in CDX, such as a MS4 Regulatory Role for NeTCGP, then you should follow the help file below to add a role for NeTMS4 instead of making a new CDX account.
    • If you need help submitting your Annual Reports, then you should follow the help file below to submit your Annual Reports. Annual reports are due for all Small MS4 permittees by October 1 of each year.

FAQ

What does it mean to be a Phase I or Phase II MS4?

In 1990, EPA established Phase I of the National Pollutant Discharge Elimination System (NPDES) stormwater program. The Utah Pollutant Discharge Elimination System (UPDES) is the Utah version of NPDES, which is the permit system mandated by § 402 of the Clean Water Act to control pollutants in waters of the U.S., including storm water. The Phase I program for MS4s requires operators of medium and large MS4s (generally those that serve populations of 100,000 or greater) to implement a stormwater management program as a means to control polluted discharges from these MS4s.  

The Phase II Rule extends coverage of the UPDES stormwater program to certain small MS4s that are located within an urbanized area of more than 50,000 population. A small MS4 is any MS4 not already covered by the Phase I program. The Phase II Rule automatically covers on a nationwide basis all small MS4s located in urbanized areas, and those small MS4s located outside of those areas that the State of Utah designates.
