PART IV. PROJECT DESCRIPTION Description of cleanup site, including a description of the source(s) of contamination and the extent of contamination and any additional contamination anticipated in the local groundwater from other possible sources: Cleanup activities associated with the unexpected release of gasoline from an unused 12,000 AST in the northeast corner of the Hyrum Short Stop site. Released hydrocarbons impacted subsurface soils and groundwater which appear to have previous diesel impacts that migrated off-Site into an adjacent stormwater ditch. Primary source area impacted soil has been approved for excavation – approx.. 1,000 CY to date. Abatement/initial response surface water and exposed groundwater in the excavation will require treatment and discharge. Activated carbon treatment will occur prior to discharge. Cleanup oversight has been provided by DERR and DWQ. PART V. MAP Attach a topographical map of the area extending to at least 1 mile beyond the property boundaries. The map must show the outline of the facility, the location of each of its existing and proposed intake and discharge structures, each of its waste treatment, storage, or disposal facilities, and discharge locations. Include all springs, rivers, and other surface water bodies in the map. X Map Attached Figure 1 and Figure 2 PART VI. PROJECT DATES Filing your permit will grant you one year of coverage from the filing date regardless of the project duration outlined below. If you project ends early, you must file a Notice of Termination (NOT). Project Start Date: 04 / 25 /20 25 Excavation has started, the majority of water in frac tanks Project Completion Date: 04 / 25 /20 26 Notes: Treated water discharge is expected to consist of abatement/initial response and excavation water.

Outfall No. Latitude Longitude Receiving Surface Waters (Name) 1 41.63696 -111.86332 Salt Hollow Pond Discharge/Hyrum Stormwater System Are any of the discharge points located in the Colorado River Basin?  Yes X No Does the receiving water designated uses include Class 1C drinking water as defined by R317-2- 13? Yes X No Class 1C waters are “Protected for domestic purposes with prior treatment by treatment processes as required by the Utah Division of Drinking Water”. Is the project located on tribal lands? Yes X No If the facility is located on Tribal Lands the permittee must contact EPA Region VIII except for facilities on the Navajo Reservation or the Goshute Reservation, for which the permittee must contact EPA Region IX. Does the discharge flow into a storm drain before entering the receiving water body? X Yes No Be Advised: Discharges to storm drains must be approved by the storm drain authority/owner. Is the project part of the Utah Voluntary Cleanup Program (VCP)?  Yes X No Description of Discharge location and conveyance system to live water: The Discharge location will be the outfall of Salt Hollow Pond. The discharged water will enter the Hyrum City Stormwater system along N 200 W and flow generally west through the Hyrum pumpstation, then generally northwest to the city outfall at the intersection of N 400 W and S 1900 E. Water will then continue west-northwest until its eventual discharge into Pelican Pond. PART VIII. INFLUENT AND EFFLUENT CONCENTRATIONS Complete attached Table A and list any additional pollutants (not included in Table A) with influent and/or effluent concentrations here: Laboratory analytical reports attached. NOI UPDES General Permit For Treated Groundwater and Surface Water Page 4 of 8 PART VIII. INFLUENT AND EFFLUENT CONCENTRATIONS continued Discharge IS to Class 1C Water: 1.In addition to completing Table A, influent sampling including total toxic organics (TTO results must be attached. See attached Table B for list of TTO constituents. No permits for discharge to Class 1C Waters will be issued prior to influent sampling being conducted and results received. 2. An analysis of alternative disposal methods of the treated groundwater must be attached. This analysis must include an economic comparison of the alternative disposal methods. If no other disposal methods are feasible the analysis must demonstrated the consideration of other methods such as trucking and/or discharge to a treatment facility. 3. Discharge is NOT to Class 1C Water: 1.In addition to completing Table A, influent sampling including total toxic organics OR a report documenting why influent sampling is not needed for this project and an estimation of anticipated influent constituents concentrations. 2. In accordance with Part I.D. the permittee may petition Total Petroleum Hydrocarbon (TPH-GRO and TPH-DRO) analyses may be substituted for the TTO analyses. If approved maximum daily effluent limitations of 1.0 mg/LTPH- GRO and TPH-DRO will be substituted for the TTO effluent limitation. PART IX. DESCRIPTION OF TREATMENT SYSTEM Description of the current or proposed treatment system, including discharge flow rate (attach a flow diagram): Water will be recovered by a pump and transferred to an approximate 19,000 gallon weir/separation tank. A pump trailer will convey water from the weir tank, through a BF-400 bag filter system consisting of four (4) units running 2x2 in parallel. Water from the filters will then pass through two (2) 2,000 lbs virgin carbon vessels prior to discharge into Salt Hollow Pond. Anticipated discharge 50-90 gpm. It is noted that Effluent pH was above 9.0. This is attributed to residual ash that is being removed from the pore structure of the carbon. pH will be monitored frequently during discharge and pH adjustment will be implemented as required to prevent discharge exceedances.
