This Permit shall become effective on June 1, 2024.This Permit expires at midnight on May 31, 2029.Signed this 31st day of May, 2024._________________________John K. Mackey, P.E.DirectorDWQ-2024ContentsCOVERAGE UNDER THIS PERMIT Permit Authority and Area Permitting Authority. Under the Clean Water Act’s National Pollutant Discharge Elimination System (NPDES) program the Environmental Protection Agency (EPA) has granted primacy to the state of Utah with its storm water permit program. The Utah Admin. Code R317-8-2.5 authorizes the issuance of General Permits for categories of point sources within the same geographical area with discharges that are from similar types of operations and wastes, and that require similar effluent limitations and monitoring. Permit Area. This Permit Covers all areas of the State of Utah except for Indian lands. The State of the Utah, Department of Environmental Quality, Division of Water Quality (DWQ) does not have permit authority for Indian Lands Storm water permits for Indian lands within the State must be acquired through EPA Region VIII, except for facilities on the Navajo Reservation or on the Goshute Reservation which must acquire storm water permits through EPA Region IX. Coverage Under this Permit This Permit shall apply to construction dewatering of uncontaminated groundwater or surface water sources due to construction activities, hydrostatic testing of pipelines or other fluids vessels, water used in disinfection of drinking water vessels and other similar discharges in the State of Utah that have no discharge of process wastewater other than those described in this paragraph. Discharges Covered Under this Permit include: In-stream dewatering: cofferdams, drill hole or pylon development; Surface area dewatering: water pumped from disturbed surface areas (trenches, sumps, excavation pits, similar points of accumulation or other excavations associated with construction activities where sediment-laden ground water or surface water/storm inflow must be removed); and Ground water dewatering: water discharged from well development, well pump tests, or pumping of ground water from a construction area. Dewatering wells located within an active area of disturbance is subject to this Permit. Common methods of ground water dewatering from a construction area include sumps, wells, and well-points; and Hydrostatic Testing: such as piping systems, gas cylinders, fire extinguishing, storage tanks, boilers, chemical pipelines, and pressure vessels that are tested for strength and leaks. The following discharges are not covered under this Permit: This Permit does not authorize discharge from dewatering activities at hazardous waste sites, leaking chemical tanks, the discharge of toxic materials, or discharge of contaminated water, sanitary or industrial wastes (other than what is normally encountered at excavation and construction sites) at any location. This Permit does not authorize the discharge of treated groundwater or surface water due to cleanup of spills of hazardous or regulated materials, including fuel spills This Permit does not constitute authorization under 33 U.S.C. § 1344 (Section 404 of the Clean Water Act) of any stream dredging or filling operations. Any dewatering discharge that is land applied and does not reach state waters or the storm drain is not regulated under this Permit, although a DWQ Groundwater Discharge Permit may be required. An authorization to discharge under this Permit, where the activity discharges to a municipal or private storm drain owned by another party or discharges to private or public lands or water ways, does not convey any rights or authorization to discharge to the above stated location. The permittee must contact the owner of the municipal separate storm sewer system (MS4), private storm drain or the private or public lands or water way and obtain permission to discharge.

If an operator fails to submit in a timely manner an individual UPDES permit application as required by the Director, then the applicability of this Permit to the individual UPDES permittee is automatically terminated at the end of the day specified for application submittal. EFFLUENT LIMITATION AND MONITORING REQUIREMENTS Water Quality Standards Discharge(s) must be controlled as necessary to meet applicable water quality standards. DWQ expects that compliance with the condition in the Permit will result in discharges being controlled as necessary to meet applicable water quality standards. If at any time the permittee become aware or DWQ determines that discharges are not being controlled as necessary to meet applicable water quality standards the permittee shall take correction action to minimize or prevent the discharge of pollutants and documentation as described in Part II.C.12. Narrative Standard It shall be unlawful, and a violation of this Permit, for the permittee to discharge or place any waste or other substance in such a way as will be or may become offensive such as unnatural deposits, floating debris, oil, scum or other nuisances such as color, odor taste, or cause conditions which produce undesirable aquatic life or which produce objectionable tastes in edible aquatic organisms; or result in concentrations or combinations of substances which produce undesirable physiological responses in desirable resident fish, or other desirable aquatic life, or undesirable human health effects, as determined by bioassay or other tests performed in accordance with standard procedures. Specific Limitations and Self-Monitoring Requirements Effective immediately and lasting the duration of this Permit, the permittee is authorized to discharge from all Outfalls designated in the NOI. All authorized discharges shall be limited and monitored by the permittee as specified below:Table 1. Effluent Limits and Monitoring Requirements: Effluent Characteristics Discharge Limitations a, g Monitoring Requirements Average Average Daily Min Daily Max Measurement Frequency Sample Type 30 day 7 day Flow, GPD -- -- -- -- Weekly Instant Oil & Grease, visible b -- -- -- -- Daily Visual Observation Oil & grease, mg/L c -- -- -- 10 Weekly Grab pH, Standard Units h -- -- 6.5 9.0 Weekly Grab Total Suspended Solids, mg/L d 25 35e -- 70 Weekly Grab/ Composite Total Residual Chlorine (TRC), mg/L f -- -- -- -- Daily Grab a See Part VI, Definitions, for definition of terms. b Observe effluent daily for visible Oil & Grease sheen. c Sample for Oil and Grease only when a sheen is observed or other reasons to suspect the presence of oil. d The Director may allow exceptions to the total suspended solids monthly and weekly limitations on a case-by-case basis where the discharge will not exceed 45 days and the treatment system is designed, built, and operated to meet the maximum concentration limitation and there will be no significant detrimental effect on receiving water quality or downstream beneficial uses e 7-day Average is a DWQ secondary standard in Utah Admin. Code R317-3.2F; The Director may allow exceptions if the duration is short and will not cause a detrimental effect. To receive exception to the 7-day Average monitoring requirement, the permittee shall submit a request to the Director. f The use of chlorinated water for a hydrostatic testing fluid shall not be allowed unless it can be demonstrated that the chlorine dissipates prior to discharge, poses no potential for toxic impacts to the receiving waters or proper dechlorination BMPs and monitoring has been performed.
