Dear Mr. Lowder:
Subject:Construction Permit – Homewood Suites & Hampton Inn (Bryce) - Large Underground Wastewater Disposal System (LUWDS) – Located at Approximately 1200 W Hwy 12 in Bryce, Utah (Garfield
County)
The Division of Water Quality (Division) has reviewed the plans prepared by Richard Jex, P.E. of Jex Environmental Solutions, for the construction of a LUWDS to treat and dispose of
wastewater from the proposed Homewood Suites & Hampton Inn hotelsproject to be located at the subject property. The LUWDS is designed to accommodate maximum wastewater flows of 31,300
gallons per day, requiring an operating permit under Utah Administrative Code R317-5. The plans and specifications submitted on April 29, 2024 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 system will have a maximum design capacity of 31,300 gallons per day (gpd) based on estimated wastewater flow, as listed below:
Homewood Suites Hotel (110rooms @ 140 gpd each*)15,400 gpd Hampton Inn Hotel (110rooms @ 140 gpd each*)15,400 gpd Conference Center (100 people @ 5 gpd each) 500 gpd
Total31,300 gpd
*Food service and swimming pool flows are included in thisdesign flowestimate
The LUWDS will include grease interceptors, multiple septic tanks, an equalization tank, a 2-stage Orenco AdvanTex recirculating media filter treatment system, an ENR nitrogen reduction
system, a flow meter, a distribution valve, and a pressurized drainfield as listed below (see Attachment 1):

Pressurized Drainfield4 zones, each with 4 - 110’ laterals and 7 feet effective gravel depth, providing a total of 24,640 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.
LUWDS effluent is to be discharged at a concentration that does not exceed 2.5 mg/L total inorganic nitrogen (TIN). The owner, operator, and project engineer should understand that additional
monitoring requirements shall be required as part of any operating permit, once a system is constructed and approved (see Attachment 2).
The required nitrogen reduction system uses available carbon released into the wastewater stream from the wood mediacontained within the system. The LUWDS design easily allows the introduction
of additional carbon at two injection points. The Division will require equipment for providing additional carbon and for carbon monitoring, as shown in the approved plans and specifications,
if the effluent limitations listed in Attachment 2 are not achieved.
This construction permit does not address biosolids treatment, monitoring, record keeping, reporting and disposal/reuse.
The facility owner 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 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 owner or owner’s agent, in any way, of obligations to comply with other applicable regulatory requirements, or obtaining other necessary
applicable permits (e.g. food service permits, swimming pool permits, etc.) from local or other agencies. You may contact Jeremy Roberts, Southwest Utah Public Health Department (435)
986-2582, and Paul Wright, DEQ District Engineer [phone], for compliance with other local requirements.
Please note that this construction permit does not constitute an endorsement by the Division of any equipment or proprietary treatment system. In addition, the Division may choose to
limit the number of projects throughout the State where similar equipment or proprietary treatment systems are proposed. This limitation may be imposed until Division personnel can obtain
data and experience to confirm the effectiveness of equipment, proprietary treatment methods, and best management practices associated with unfamiliar wastewater treatment systems.
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://deq.utah.gov/legacy/programs/water-quality/utah-underground-injection-control/index.htmor contact Porter Henze 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) should 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 operating permit will be issued for this system by the Division, upon completion of the engineer’s final report per R317-5-8, and will detail annual inspection and reporting requirements
for this system.
Once the LUWDS is approved and the Division issues an operating permit, additional monitoring, sampling, testing, and reporting beyond the annual inspection(s) and reporting requirements
listed in R317-5-10.3 shall be required, due to the pristine characterization of sensitive groundwater in the vicinity of this LUWDS. Monitoring, sampling, testing, and reporting requirements
specific to this LUWDS are listed in Attachment 2.
An electronic copy of the approved plans is returned bearing our construction permit stamp, along with this construction permit. The stamped set must be kept available for examination
and inspections to be conducted by the Division, or for resolution of any conflicts or discrepancies that may arise during construction or installation.
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.
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
