any part of the MS4 contributes to a303(d) listed (i.e., impaired) waterbody.A 303(d) list of impaired waterbodies isavailable athttps://wq.deq.utah.gov/. Water quality impaired waters
means anysegment of surface waters that has been identified by theDirectoras failing tosupport one or more of its designated uses.If the Permittee has any discharges to animpaired waterbody,
the Permittee must comply with Part 3.1.2. and Part 3.2., if applicable, and if no dischargestoimpairedwaterbodies exist,theremainderofthisPart3.1does not apply.If the Permittee has
“303(d)” discharges described above, the Permittee shall alsodetermine whether a Total Maximum Daily Load (TMDL) has been developed by theDirector and approved by EPA for the listed
waterbody.If there is an approvedTMDL, the Permittee shall comply with all requirements associated with the TMDL(see Part 3.2.) in addition to the requirements of Part 3.1.2. If no TMDL
has been approved, thePermittee shall comply with Part 3.1.2. and will be required to meet any TMDLrequirements once it is developed and approved.TMDL requirements may be putintoeffectatanytime
duringthisPermitterm.IfthePermitteedischargestoanimpairedwaterbody,thePermitteeshallincludeinits SWMP document a description of how the Permittee will control the discharge ofthe pollutants
of concern.This description shall identify the measures and BMPs thatwillcollectivelycontrolthedischargeofthepollutantsofconcern.Themeasuresmust be presented in the order of priority

with respect to controlling the pollutants ofconcern.Where a discharge is already authorized under this Permit and is later determined tocause or have the reasonable potential to cause
or contribute to the violation of anapplicable water quality standard, theDirector will notify the Permittee of suchviolation(s). The Permittee shall take all necessary actions to ensure
future dischargesdo not cause or contribute to the violation of a water quality standard and documentthese actions as required by the Director. If violations remain or re-occur, coverageunder
this Permit may be terminated by theDirector and an alternative UPDESPermit may be issued. Compliance with this requirement does not preclude the Statefrom taking an enforcement action
as provided by the Utah Water Quality Act for theunderlyingviolation.Jordan River Watershed Wide Escherichia coli (E. coli) TMDL
The permittee discharges to waters listed on the Utah 303(d) list as impaired for E.coli for which storm water is a contributing source per the Jordan River Watershed Wide E.coli TMDL.
The permittee must update their SWMP document within 180 days to include a written plan (TMDL Compliance Plan) addressing the pollutant reduction requirements of the TMDL as it relates
to MS4s. The Jordan River E. coli TMDL MS4 Guidance Document available on the division’s website will provide supplemental information to assist MS4s in compliance with the below Permit
requirements.
The TMDL Compliance Planwill supplement and build-on the six (6) minimum control measures identified in Part 4.2 of this permit. The Permittee must develop, fund, and implement source
control BMPs that reduce the discharge of E. coli. The TMDL Compliance Plan must address the following:
Identify potential sources of E. coli in the MS4 and target specific audiences that may be contributing to the E. coli sources. Provide and document education and outreach given to the
target audiences on the impacts to water quality associated with these types of discharges and BMPs that can be implemented to reduce the discharge of E. coli.
The Permittee can meet the requirements of permit part 3.2.2.1. through contribution to a collaborative program (e.g., storm water coalition) that evaluates, identifies, and targets
sources, as well as, provides outreach that addresses E. coli.
The Permittee must maintain a written or mapped inventory of areas in the MS4 that are potential sources of E. coli (areas with septic, dense waterfowl areas, dog parks, etc.).
The Permittee must create a plan to prioritize reduction activities to address the areas and sources identified in the inventory. The plan must include BMPs the permittee will implement
over the permit term (structural and non-structural).
The Permittee must add the inventoried areas to the priority areas identified in permit part 4.2.3.3.1. and begin inspecting the additional priority areas annually at a minimum and documenting
the inspections on an inspection form.
The Permittee must add the inventoried areas to the priority areas identified in permit part 4.2.6.7.2. for street sweeping and storm sewer system maintenance and begin maintaining the
areas at the same frequency. The Permittee’s road and parking lot sweeping and storm drain system maintenance SOPs should identify all priority areas (including E. coli sources) and
must include a schedule that includes priority area frequency.
The Permittee must evaluate their written inventory of potential “high priority” permittee owned and/or operated facilities (Permit Part 4.2.6.1.) and identify sites that have potential
sources of E. coli. Permittees must add to their inventory any Permittee owned or operated dog parks, parks with open water, sites with septic, or properties that are known potential
sources of E. coli. Sites that have been identified as potential sources of E. coli must have BMPs (structural or nonstructural) that reduce the potential of the discharge of E. coli.
The Permittee must evaluate the potential E. coli generating activities below to determine whether the permittees existing SOPs for Detention and Retention Basin, Hazardous Materials
and Waste Management, Material Handling and Storage, Solid Waste Management, Spill Prevention and Control, and Sweeping & Vacuuming should target reduction of E. coli discharge. The
permittee may also create additional SOPsfor the reduction of E. coli discharge from the MS4. The potential E. coli generating activities to be evaluated are listed below:
Surface cleaning and controlling litter
Lake and lagoon maintenance
Mowing/Trimming/Planting
Inspection and Cleaning of Stormwater Conveyance Structures, Controlling Illicit Connections and Discharges, Controlling Illegal Dumpingto storm water collection and conveyance structures
Solid Waste Collection, Controlling Litter, Controlling Illegal Dumping of solid wastes
Water line Maintenance, Sanitary Sewer Maintenance, Spill/Leak/Overflow Control, Response, and Containment.
The Permittee must promote the use of Low Impact Development (LID) controls for which E. coli (listed a bacteria) has a medium or high pollutant removal effectiveness, as identified
in the Guide to Low Impact Development within Utah, Appendix C on the division’s website: https://documents.deq.utah.gov/water-quality/stormwater/updes/DWQ-2019-000161.pdf.
The Permittee must add potential E. coli reduction as a criterion for ranking when evaluating the Permittees retrofit plan (Permit Part 4.2.6.9.).
The Permittee is required to monitor and analyze E. coli (No./100 mL) at their Wet-Weather Monitoring sites that discharge to the Jordan River and its tributaries in Permit Part 5.2.2.4.

The Permittee must report annually on their TMDL compliance by submitting the TMDL Compliance Report section within the annual report form on the Division’s website. The first TMDL Compliance
Report within the annual report will be due to the Division by October 1, 2024. The reporting will include identification of problem areas for which source control BMPs were developed,
the cost, and the anticipated pollutant reduction. NitrogenandPhosphorusReductionAspartofthePermittee’sStormWaterManagementProgram(SWMP),thePermittee must specifically address the reduction
