Shelley Executive Director DIVISION OF WATER QUALITY John Mackey, P.E. Interim Director SPENCER J. COX Governor DEIDRE HENDERSON Lieutenant Governor March 15, 2024 VIA EMAIL READ RECEIPT REQUESTED Tim Stay CEO The Other Side Village 667 East 100 South Salt Lake City, Utah, 84102 Subject: UPDES General Permit Coverage No. UTG790103 The Other Side Village, Salt Lake City, Utah Dear Mr. Stay: Enclosed is a signed copy of the Utah Pollutant Discharge Elimination System (UPDES) General Permit Notice of Intent (NOI), which combined with this letter, authorizes discharges for the facility referenced above. Coverage under the Treated Groundwater and Surface Water Genera Permit for this facility is referred to as UPDES permit number UTG790103. The conditions and requirements of the permit will be effective for one year beginning March 15, 2024. For reference, a copy of the general permit is available at: https://deq.utah.gov/water-quality/updes-permitting- program#general-treated-gw. After reviewing your NOI and associated information, it was determined that effluent monitoring and limits will be required as described in section I.E of the Treated Groundwater General Permit. The DWQ approved TPH-GRO and TPH-DRO monitoring in lieu of the Total Toxic Organics (TTO) monitoring requirement. Additionally, monthly effluent monitoring will be required for Arsenic. Zinc and Copper effluent limitations are dependent on water hardness. The effluent limits for Zinc and Copper have been adjusted to reflect a water hardness of 428 mg/L CaCO3 based on sample results provided to DWQ. Page 2 UTG790103 The Other Side Village The daily max limitation for Total Recoverable Copper was calculated to be 0.032 mg/L and 0.041 mg/L for Total Recoverable Zinc. Based on the adjusted effluent limits monitoring for Copper and Zinc will not be required. Monitoring and Limit requirements for the UTG790103 permit are as follows: The permit requires that monitoring results be summarized and reported on a Discharge Monitoring Report (DMR). The DMR shall be submitted electronically monthly the Environmental Protection Agency’s (EPA) electronic reporting system: NetDMR https://npdes- ereporting.epa.gov/net-netdmr. The DMR is due by the 28th day of each month for the previous month’s discharge activity. When discharging activities cease, please notify the Division by submitting a Notice of Termination form, which can also be obtained at: https://deq.utah.gov/water-quality/current-permits-and-forms-updes-permitting-program#general UPDES General Permit Coverage for the Discharge of Treated Groundwater is for 12 months or less. Within 6 months of permit issuance, please evaluate your discharge timeline. If dewatering discharges are expected to extend greater than 12 months from the issuance date, an individual permit will need to be obtained. Individual permits require 6 months for issuance. Please keep DWQ informed of your project status. A fee schedule was included in the Utah Department of Environmental Quality Budget appropriation request at the direction of the Legislature and in accordance with Utah Code annotated 19-1-201.
