The RO system would have a waste streamwith higher concentrations of contaminates such as Total Dissolved Solids (TDS), Sulfate, Sodium, Chloride, etc.This would infiltrate into the ground water system and over time would degrade that system. Therefore, this discharge is required to be placed in lined evaporation ponds. Therefore, the lined evaporation ponds required a Ground Water Discharge Permit by Rule and a Construction Permit. On August 22, 2024, DWQ received the Construction Documents for the Lost Creek State Park. This was a complete set of documents for all construction at the Park.These were all prepared by CivilScience and signed by Cody C. Howick P.E., ProjectManager and Ryan Devitt P.E. Assistant Project Manager.Mr.Howick and Mr. DevittareaUtah Certified ProfessionalEngineers (P.E.). After talking with Mr. Devitt and explaining that DWQ only needed the documents concerning the water system including the evaporation ponds, Mr. Devitt sent over just those drawings on October 28, 2024. Thewater system and evaporation ponds drawing set include the following:Sizing and location of evaporation ponds;Pump house and drain lines leading to evaporation pond: andWell and pump house equipment: etc. Permit-By-RuleDetermination Below are the relevant factors evaluated in determining that the proposed operation qualifies forpermit-by-ruleandthatdischargewillhaveademinimisactualorpotentialeffectongroundwaterqualityand beneficialuses of ground waterresources under UAC R317-6-6.2.A(25).The main concern is the RO system waste stream will now be contained in linedevaporation ponds.The Evaporation Ponds will be lined with a minimum 40-mil-thick Reinforced Polyethylene(RPE)liner and 8 oz Geotextile.The evaporation pond will minimize any infiltration of the RO system waste stream into the shallow aquifer system.Placement of three down gradient piezometer to detect possible leakage from the evaporation ponds ConditionsofApproval ThefollowingconditionsarerequiredunderthisPermit-By-Rule:TheEvaporationPondmayonlybeusedforthe RO system waste streamandwell water.Nothingelsemaybeputin thepond.CeaseoperationsandnotifyDWQimmediatelyifasheenorodorisdetectedonanyofthewaterin thepond.

ConstructionPermit On August 22, 2024, DWQ received the Construction Documents for the Lost Creek State Park. This was a complete set of documents for all construction at the Park. These were all prepared by CivilScience and signed by Cody C. Howick P.E., Project Manager and Ryan Devitt P.E. Assistant Project Manager.Mr.Howick and Mr. Devitt areaUtah Certified ProfessionalEngineers (P.E.). On October 28, 2024, DWQ received a subset of documents concerning the water system including the evaporation ponds.Those drawings did not include any specifications (compaction, moisture content, etc.) for the soils and berms of the evaporation ponds. This was communicated to Mr. Devitt and on November 9, 2024, DWQ received the drawing with those required changes. Thefollowingis asummaryoftheproposedmajorconstructionprojects for the water system and evaporation ponds:Construction of a well and pump house including the equipment:Placement of drain line to the evaporation ponds: Construction of6newevaporationpondsthatwillbelinedwitha 40 mil Reinforced Polyethylene(RPE)liner and 8 oz Geotextile; andPlacement of three down gradient piezometer to detect possible leakage from the evaporation ponds. The plans and specifications, as submitted, comply with the Utah Water Quality Rules,(R317, Utah Administrative Code).A Construction Permit is hereby issued as constituted bythisletter,subject to thefollowingconditions:AnyrevisionsormodificationstotheapprovedplansandspecificationsmustbesubmittedtoDWQforreviewandapproval,beforeconstructionorimplementationthereof.Pleasesubmitanychangesforreviewandapprovaldirectly to Woodrow Campbell, P.E., of the DWQ Ground Water ProtectionSection.A written operations and maintenance manual, containing a description ofthefunctioningofthefacilities,anoutlineofroutinemaintenanceprocedures, and all checklists and maintenancelogs needed for properoperation of the system, must be submitted and approved before the finalinspectionand operation ofthesystem.The approved facilities must not be placed in service unless DWQ hasconductedafinalinspection,reviewedandapprovedtheAs-BuiltConstruction Certification Report, and provided written authorization toplacetheconstructed facilities in service.Construction activities that disturb one acre or more are required to obtain coverage under the Utah Pollutant Discharge Elimination System (UPDES) Storm Water General Permit for Construction Activities. The permit requires the development of a storm water pollution prevention plan (SWPPP) to be implemented and updated from the commencement of any soil disturbing activities at the site until final stabilization of the project.
