EPA’s Storm Water Phase II Rule establishes an MS4 storm water management program that is intended to improve the Nation’s waterways by reducing the quantity of pollutants that are introduced into storm sewer systems during storm events. Common pollutants include oil and grease from roadways, roadway salts and deicing materials, pesticides and fertilizers from lawns, sediment from construction sites, and carelessly discarded trash, such as cigarette butts, paper wrappers, and plastic bottles. When deposited into nearby waterways through MS4 discharges, these pollutants can impair the waterways, thereby discouraging use of the resource, contaminating water supplies, and interfering with the habitat for fish, other aquatic organisms, and wildlife. In 1990, EPA promulgated rules establishing Phase I of the National Pollutant Discharge Elimination System (NPDES) storm water program. The Phase I program for MS4s requires operators of “medium” and “large” MS4s, that is, those that generally serve populations of 100,000 or greater, to implement a storm water management program as a means to control polluted discharges from these MS4s. The Storm Water Phase II Rule extends coverage of the NPDES storm water program to certain “small” MS4s but takes a different approach to how the storm water management program is developed and implemented. MURRAY CITY CHARACTERISTICS General Information Murray City Storm Drain System falls under the Public Works Department. The Public Works Director can be contacted at the following address and phone number. Public Works Facility 4646 S. 500 W. Murray, Utah 84123 [PHONE REDACTED] Population: 49,917 Size: 12 square miles Geographic Description: Murray City is located from approximately 4500 S. to 6600 S. and 1300 West to the Van Winkle Expressway on the east Receiving Waters: Jordan River, Big Cottonwood Creek, Little Cottonwood Creek Annual precipitation: Average precipitation is 16.1 inch/yr ---PAGE BREAK--- Storm Water Management Plan 2020 4 Type of Community: Land use is approximately 10% vacant land 45% residential 20% commercial and industrial 15% transportation 10% parks and open area Latitude: 40O 40′ 18.11″ N Longitude: 111O 54′ 24.75″ W History Murray City was officially recognized in January 3, 1902. The City is made up of a wide variety of ethnic backgrounds and religions. The City is governed by a Mayor-Council form of government with a mayor and 5 council members. The City has its own water, power, fire, police, and public services departments. Permit Application Murray City is considered an MS4 Phase II permittee. Phase II designates MS4’s that serve populations less than 100,000. The permit issued by the State of Utah under the direction of the EPA allows the city to discharge storm water runoff to the waters of the state. Cities required to permit under Phase II are allowed to cooperate and work together with neighboring cities in the application process. The permittee may join with a Phase I city or another Phase II city in applying for a permit. Individual MS4s may share responsibility for program development with neighboring communities and/or take advantage of existing local or state programs. Notice of Intent (NOI) and Permit Requirements The chosen measurable goals, submitted in the NOI as a permit application, become the required storm water management program; however, the NPDES permitting authority can require changes in the mix of chosen BMPs and measurable goals if all or some of them are found to be inconsistent with the provisions of the Phase II Final Rule. Likewise, the permittee can change its mix of BMPs if it determines that the program is not effective as it could be. Reports The permit requires that the city review the SWMP annually, report on activities and make any updates. Generally, the annual report will include the following information:  The status of compliance with permit conditions, including an assessment of the appropriateness of the selected BMPs and progress toward achieving the selected measurable goals for each minimum measure;  Results of any information collected and analyzed, including monitoring data if any;  A summary of the storm water activities planned for the next reporting cycle;  A change in any identified BMP or measurable goals for any minimum measure; and  Notice of relying on another governmental entity to satisfy some of the permit obligations. ---PAGE BREAK--- Storm Water Management Plan 2020 5 Record Keeping Records required by the NPDES permitting authority must be kept for at least 5 years and made accessible to the public at reasonable times during regular business hours. Penalties The NPDES permit that the operator of a regulated small MS4 is required to obtain is federally enforceable, thus subjecting the Permittee to potential enforcement actions and penalties by the NPDES permitting authority if the permittee does not fully comply with application or permit requirements. This federal enforceability also includes the right for interested parties to sue under citizen suit provision (section 405) of CWA.
