Subject:Construction Permit – Uintah SpringsBusiness Park - Large Underground Wastewater Disposal System (LUWDS)addition – Located at approximately 6171 South 2500 East in Uintah, Utah.
Dear Mayor Cutler:
The Division of Water Quality (Division) has reviewed the plans (DWQ-2024-008763) submitted byRichard Jex, P.E. of Jex Environmental Solutions,for construction of an addition to theexisting
large onsite wastewater disposal system (LUWDS) which treats and disposesof wastewater from the subject property. The proposed LUWDS addition will not increase any wastewater flow,
will add additional septic tank effluent treatment, and is designed to serve a commercial development with peak wastewater flows of 12,500 gallons per day (gpd), requiring an operating
permit under Utah Administrative Code R317-5. The plans submitted onDecember 6, 2024 basically comply with the Utah Water Quality Rules, Utah Administrative Code R317-5. A Construction
Permit, as constituted by this letter, is hereby issued subject to the following conditions:
Any revisions or modifications to the approved plans and specifications must be submitted to the Division for review and approval, before construction or implementation thereof.
The LUWDS will have a maximum design capacity of 12,500 gallons per day (gpd) based on estimatedwastewater flows, as follows:
Food Service (2 Units @ 2,500 gpd each) 5,000 gpd
Office/Warehouse (20 Units @ 350 gpd; restroom included) 7,000 gpd
Retail Shops (1 Unit @ 500 gpd/public restroom) 500 gpd
Total Wastewater Flow 12,500 gpd
The LUWDS will include multiple septic tanks, an Orenco AdvanTexeffluent treatment system, and a pressurized drainfield as listed below (see Attachment 1):
Septic & Equalization Tank(Existing)32,000 gallons
Effluent Treatment System(Existing)1- Orenco AdvanTex AX-Max 275-42(New)1 - Orenco AdvanTex AX-Max 275-42
Flow Meter(Existing)1 – Siemens 3100
Disinfection(Existing) 3 – Sanitron S2400 C
Drainfield(Existing) Pressurized deep trench drainfield, with 6 zones; Each zone has 3 - 123’ laterals with 3.5’ effective depth; Providing a total of 15,498 square feet of absorption
area.
The approved facilities may not be placed in service prior to the following inspections conducted by the Division or designated representative:
Inspecting and verifying the water tightness of all septic tanks.
Conducting representative inspection(s) of the components of the drainfield prior to backfilling, as necessary.
Completing a final inspection, and authorizing use of the facilities in writing through the issuance of an Operating Permit.
Please make the necessary arrangements for any inspection by calling Robert Beers at [phone]. The project engineer or designated representative must be present during key construction
events, to verify that construction and installation was performed as per design. Documentation of these inspection visits must be provided when the completion letter is submitted to
the Division following final inspection.
One additional Orenco AdvanTex textile filter treatment unit will be installed under this permit to service the onsite system. Treated effluent is to be discharged at a concentration
that does not exceed discharge standards listed in R317-4-13. Table 7.3. The permittee should understand that additional monitoring requirements may be required as part of any operating
permit, once a system is constructed and approved.
This construction permit does not address biosolids treatment, monitoring, record keeping, reporting and disposal/reuse.
Uintah City (permittee) has agreed to serve as the sponsoring body politic for this LUWDS as required in R317-5-3.12.
The permittee shall be responsible for proper construction, operation, maintenance, inspection, and reporting to the Division as required under Utah Administrative Code R317-5 for the
proposed LUWDS.
No modifications or additional connections of any type may be made to this LUWDS without the review and written approval of the Division.
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. For more information, please contact Jeanne Riley at [phone]. To obtain permit coverage on-line, please go to:
https://deq.utah.gov/water-quality/general-construction-storm-water-updes-permits
The issuance of this permit does not relieve the permittee, in any way, of obligations to comply with other applicable regulatory requirements, or obtaining other necessary applicable
permits from local or other agencies. You may contact Summer Day, Weber-MorganHealth Department [phone], for information regarding local requirements.
The construction permit will expire one year after the date of this permit, unless substantial progress is made in the construction of approved facilities or the plans and specifications
have been resubmitted and the construction permit is reissued.
According to the Administrative Rules for the Underground Injection Control (UIC) Program (UAC R317-7), the proposed onsite domestic wastewater disposal system, which has a cumulative
design flow rate greater than 5,000 gallons per day, is classified as a Class V injection well. Owners and operators of all Class V injection wells are required to submit inventory
information for compliance with this program. Please submit a completed Utah UIC Inventory Information Form for UIC-Regulated Domestic Wastewater Disposal Systems, which is available
online from the Division UIC homepage at the following link: https://documents.deq.utah.gov/water-quality/ground-water-protection/underground-injection-control/DWQ-2018-000358.pdfor
contact Porter Henze by email at [e-mail] or by telephone at [phone].
The Utah UIC Program Rules prohibit authorization of underground injections “which would allow movement of fluid containing any contaminant into underground sources of drinking water
(USDW) if the presence of that contaminant may cause a violation of any primary drinking water regulation (40 C.F.R. Part 141 and Utah Primary Drinking Water Standards R309-200-5), or
which may adversely affect the health of persons” or which “may cause a violation of any ground water quality rules that may be promulgated by the Utah Water Quality Board” (R317-7-5.3).
If after reviewing the information submitted with the UIC Inventory Information Form, the Division determines operation of the Class V injection well does not present a potential for
contaminating a USDW as described above, the Class V well may be allowed to operate under authorization-by-rule status under the UIC Rules. If, however, it is determined that operation
of the Class V injection well could potentially contaminate a USDW, additional conditions will be made on the operating permit for this system.
A copy of the Operation & Maintenance manual, detailing service and maintenance of the entire system (including drainfield dispersal area) will be required to be submitted to the Division

prior to final inspection and approval to operate. The person identified for maintenance must be listed in this manual and must have a Level 3 Onsite Certification per R317-11. Additionally,
the engineer must provide ‘as-built’ plans of the installed system.
An authorization-to-use letter will be issued for this system by the Division, upon completion of the engineer’s final report per R317-5-1.3.
Once the LUWDS is approved and the Division issues an authorization-to-use letter, the owner shall be responsible to obtain an operating permit from the Weber-Morgan Health Department.
Please advise us of the beginning of construction. This will enable us to schedule periodic inspections. We request that a copy of as-built drawings be provided after the final inspection
has been conducted by the Division, and completed works have been placed into service. This will enable us to keep our information accurate.
An electronic copy of approved plans and specifications is returned bearing our construction permit stamp. These plans, whether electronic or paper hard copies, must be kept available
for examination and inspection to be conducted by a representative of the Division or for resolution of any conflicts or discrepancies that may arise during construction or installation.
The Division of Water Quality values your feedback to help us improve the permitting process to better meet your needs. Please go to http://www.waterquality.utah.gov/ (click on the
“Feedback” link on the lower right side of the page) to complete a short customer survey.
If we can be of further assistance, please contact Robert Beers of my staff at [phone].
Sincerely,
John K. Mackey, PE
