must determine whether storm water discharge from any part of the MS4contributes to a 303(d) listed (i.e., impaired) waterbody.A 303(d) list of impairedwaterbodiesisavailableat:https://wq.deq.utah.gov/.
Waterqualityimpairedwaters means any segment of surface waters that has been identified by the Directoras failing to support one or more of its designated uses.If the Permittee has anydischarges
to an impaired waterbody, the Permittee must comply with Part 3.1.2. and Part 3.2., if applicable, andif no discharges to impaired waterbodies exist, the remainder of this Part 3.1 does
notapply.IfthePermitteehas“303(d)”dischargesdescribedabove,thePermitteemustdeterminewhether a Total Maximum Daily Load (TMDL) has been developed by the Directorand approved by EPA for

has been approved, the Permittee mustcomply with Part 3.1.2.and will be required to meet any TMDL requirements once itisdevelopedand approved.IfthePermitteedischargestoanimpairedwaterbody,thePermitteemustincludeinitsSWMP

prioritywithrespecttocontrollingthepollutantsof concern.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, the Director will notify the Permittee of suchviolation(s). The Permittee must 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,
coverageunderthisPermitmaybeterminatedbytheDirectorandanalternativeGeneralPermitorIndividual Permitmay be issued. Compliance with this requirementdoesnotpreclude the State from taking
an enforcement action as provided by the Utah WaterQualityActforthe underlyingviolation.Jordan River Watershed Wide Escherichia coli (E. coli) TMDLPermittees that discharge to waters
listed on the Utah 303(d) list as impaired for E.coli for which stormwater is a contributing source per the Jordan River Watershed Wide E.coli TMDL must update their SWMP document within
180 daysto 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 Plan will supplement and
buildon 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 permitpart 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 part4.2.6.6.2.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.Permittees must evaluate the potential E. coli generating activities below to determine whether existing SOPs should target reduction of E.coli
discharge or if additional SOPs should be developed for the reduction of E. coli discharge from the MS4:Roads, highways, and parking lots:Surface cleaning and controlling litterParks
and open space:Lake and lagoon maintenanceParks and open space: Mowing/Trimming/PlantingStorm water collection and conveyance system: Inspection and Cleaning of Stormwater Conveyance
Structures, Controlling Illicit Connections and Discharges, Controlling Illegal DumpingMaterial storage areas: Solid Waste Collection, Controlling Litter, Controlling Illegal DumpingStorm
water collection and conveyance system: Water line Maintenance, Sanitary Sewer Maintenance, Spill/Leak/Overflow Control, Response, and Containment.Permittees 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.Permittees must add potential E. coli reduction as
a criterion for ranking when evaluating the Permittees retrofit plan (Permit Part 4.2.6.9.).Permittees 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.
