Until such time as this permit expires or is modified or revoked, the permittee is authorized to operate a large underground wastewater disposal system (LUWDS) in conformance with all
the requirements, limitations, and conditions set forth in Utah Administrative Code R317-5, with the attached schedules as follows:
SCHEDULE A
Waste Disposal LimitationsThe permittee is authorized to operate and maintain a large underground wastewater disposal system (LUWDS) that hasbeen constructed in accordance with plans
and specifications approved by the Division of Water Quality and with the following conditions:System type:Conventional Gravity
Conventional with Pump-to-Gravity
Pressure Distribution
Alternative (describe)_____________________________________________________Maximum Daily Design Flow:8,410 gallons per day (gpd)Includes flow from multiple systems: Campground (2,920
gpd); Scout Cove Trailhead (2,880 gpd); Campground Restrooms (1,920 gpd); Office / Entrance (450 gpd); Maintenance Building (270 gpd); Upper Galoot and Sand Dune Picnic Areas (flows
unknown).
Components of wastewater disposal system (check all that apply):

BedCampground Restrooms (100’ x 63’) Mound_______________________________ Other (describe):Scout Cove: 1-3000 & 1-1500 gal tanks in series; CG RRs: 1-7500 gal;Office: 1-1000 gal; Maintenance
Building: 1-900 gal tanks
Drainfield media:Gravel;Chambers (Describe)Scout Cove has chambers. All others have gravel.Effluent parameters will meet R317-4 for domestic wastewater or additional treatment may be
required. Discharge of untreated or partially treated sewage or septic tank effluent directly or indirectly to the ground surface or to the surface waters of the State of Utah constitutes
a public health hazard and is prohibited. This permit does not relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law(s), rule(s)
or standard(s). No cooling water, air conditioner water, groundwater, oil, hazardous materials, roof drainage, storm water runoff, or other aqueous or non-aqueous substance which is,
in the judgment of the Division, detrimental to the performance of the LUWDS or to groundwater, shall be discharged into the wastewater treatment system.No activities shall be conducted
that could cause an adverse impact on existing or potential beneficial uses of groundwater.
