DESCRIPTION OF FACILITY
The Coalville City Wastewater Treatment Facility (CWWTF) is located at 50 West 100 North, Coalville, Summit County, Utah in 2014. The facility serves the City of Coalville with the outfall
located at latitude 40°55'13" and longitude 111°24'09". The facility has a maximum monthly design flow of0.58 MGD with an average daily flow rate of0.32 MGD.
The facility consists of screening and grit removal, two parallel Modified Luzack-Ettinger (MLE) process trains, two secondary clarifiers and UV disinfection prior to discharge to an
unnamed tributary to Chalk Creek in the Upper Weber River watershed. Biosolids are hauled to an offsite facility located at the Three Mile Canyon Landfill.
SUMMARY OF CHANGES FROM PREVIOUS PERMIT
There have been no changes to the facility since the previous permit cycle.
DWQ has conducted reasonable potential analysis (RP) on all new and renewal applications received after January 1, 2016. A quantitative reasonable potential analysis (RP) was not able
to be performed because there was insufficient data. Quarterly metals sampling has been added to this permit to allow for sufficient metals data for the next permit renewal.
Seasonal effluent limitations for temperature have been added to this permit.
Effluent limitations for dissolved oxygen (DO) have increased from a daily minimum of 5.5 mg/L to 8.0 mg/L.
DISCHARGE
DESCRIPTION OF DISCHARGE
CWWTF has been reporting self-monitoring results on Discharge Monitoring Reports on a monthly basis. There have been no significant discharge violations during the past five-year permit
cycle. OutfallDescription of Discharge Point
001 Located at latitude 40°55'13" and longitude 111°24'09". The 15" PVC pipe discharges to an unnamed tributary of Chalk Creek, immediately above its junction with the Weber River
and Echo Reservoir.
RECEIVING WATERS AND STREAM CLASSIFICATION
The final discharge is to an unnamed tributary of Chalk Creek, which flows into the Weber River just above Echo Reservoir. Chalk Creek and the Weber River are classified as 1C, 2B, 3A
and 4 Utah Administrative Code (UAC) R317-2-13:
Class 1C -- Protected for domestic purposes with prior treatment by treatment processes as required by the Utah Division of Drinking Water
Class 2B -- Protected for infrequent primary contact recreation. Also protected for secondary contact recreation where there is a low likelihood of ingestion of water or a low degree
of bodily contact with the water. Examples include, but are not limited to, wading, hunting, and fishing.
Class 3A -- Protected for cold water species of game fish and other cold-water aquatic life, including the necessary aquatic organisms in their food chain.
Class 4 -- Protected for agricultural uses including irrigation of crops and stock watering.
TOTAL MAXIUM DAILY LOAD (TMDL) REQUIREMENTS
According to DWQ 2022 Integrated Report, 303(d) Assessment, Chalk Creek1-Coalville (Chalk Creek and tributaries from confluence with Weber River to South Fork confluence, UT16020101-010_00)
supports all designated uses.
Echo Reservoir (UT-L-16020101-001_00), located immediately downstream of the discharge, is
listed as impaired (Class 3A use) for total phosphorus.
The Rockport Reservoir and Echo Reservoir Total Maximum Daily Load study was approved March 26, 2014. The TMDL limited Coalville WWTP’s total phosphorus load to 582 kg annually and
291 kg during the summer (April 1st - September 30th) and total nitrogen to 5,819 kg annually and 2,909 kg during the summer.
BASIS FOR EFFLUENT LIMITATIONS
Limitations on total suspended solids (TSS), biochemical oxygen demand (BOD5), E. coli, pH and percent removal for BOD5 and TSS are based on current Utah Secondary Treatment Standards,
UAC R317-1-3.2.
The oil and grease is based on best professional judgment (BPJ). Limitations on total flow, whole effluent toxicity, DO, total ammonia, metals, WET testing, and temperature are based
on the Wasteload Analysis. Nitrogen and phosphorus loading limitations are based on the Rockport Reservoir and Echo Reservoir Total Maximum Daily Load. Attached is a Wasteload Analysis
for this discharge into the unnamed tributary of Chalk Creek. It has been determined that this discharge will not cause a violation of water quality standards. An Antidegradation Level
II review is not required since the permit is a renewal with no increase in flow or concentration over that which was approved in the previous permit. The permittee is expected to be
able to comply with these limitations.
Reasonable Potential Analysis
Since January 1, 2016, DWQ has conducted reasonable potential analysis (RP) on all new and renewal applications received after that date. RP for this permit renewal was conducted following
DWQ’s September 10, 2015 Reasonable Potential Analysis Guidance (RP Guidance).There are four outcomes defined in the RP Guidance: Outcome A, B, C, or D. These Outcomes provide a frame
work for what routine monitoring or effluent limitations are required
A quantitative RP analysis was not performed because there was insufficient data. Metals sampling will be required to be monitored during this permit cycle.

BIOSOLIDS
For clarification purposes, sewage sludge is considered solids, until treatment or testing shows that the solids are safe, and meet beneficial use standards. After the solids are tested
or treated, the solids are then known as biosolids. Class A biosolids, may be used for high public contact sites, such as home lawns and gardens, parks, or playing fields, etc. Class
B biosolids may be used for low public contact sites, such as farms, rangeland, or reclamation sites, etc.
DESCRIPTION OF TREATMENT AND DISPOSAL
The Permittee submitted their 2022 annual biosolids report on February 7, 2023. The report states the Permittee produced 27.24 dry metric tons (DMT) of solids.
CWWT screens the influent to remove the larger pieces of debris and Modified Luzack-Ettinger (MLE) process. After treatment, the biosolids are de-watered by screw press and hauled elsewhere
for disposal.
If the biosolids are hauled to another facility to meet land application requirements for sale or giveaway to the public, that facility must have a valid UPDES biosolids permit and will
be responsible for meeting all requirements of 40 CFR 503.
Biosolids were hauled to the 3 Mile Canyon Landfill by. Approximately 27.24 DMT were hauled off-site to the landfill for disposal.
SELF-MONITORING REQUIREMENTS
Under 40 CFR 503.16(a)(1), the self-monitoring requirements are based upon the amount of biosolids disposed per year and shall be monitored according to the chart below.

CWWTFhas produced and disposed of an average of disposed of 27 DMT/year of biosolids, therefore they should sample at least once a year. However, CWWTF transfers the biosolids to the
Three Mile Canyon Landfill, and as long as they continue to do this, they are only required to sample when requested by the landfill according to 40 CFR 258 for the landfill.
Landfill MonitoringUnder 40 CFR 258, the landfill monitoring requirements include a paint filter test. If the biosolids do not pass a paint filter test, the biosolids cannot be disposed
in the sanitary landfill (40 CFR 258.28(c)(1). CWWTF disposed of 27.3 DMT of biosolids at the 3 Mile Canyon Landfill.
BIOSOLIDS LIMITATIONS
Heavy MetalsClass A Biosolids for Home Lawn and Garden UseThe intent of the heavy metals regulations of Table 3,40 CFR 503.13 is to ensure the heavy metals do not build up in the soil
in home lawn and gardens to the point where the heavy metals become phytotoxic to plants. The permittee will be required to produce an information sheet (see Part III. C. of the permit)
to made available to all people who are receiving and land applying Class A biosolids to their lawns and gardens. If the instructions of the information sheet are followed to any reasonable
degree, the Class A biosolids will be able to be land applied year after year, to the same lawns and garden plots without any deleterious effects to the environment. The information
sheet must be provided to the public, because the permittee is not required, nor able to track the quantity of Class A biosolids that are land applied to home lawns and gardens.Class
A Requirements With Regards to Heavy Metals If the biosolids are to be applied to a lawn or home garden, the biosolids shall not exceed the maximum heavy metals in Table 3 below. If
the biosolids do not meet these requirements, the biosolids cannot be sold or given away for applications to home lawns and gardens.Class B Requirements for Agriculture and Reclamation
Sites The intent of the heavy metals regulations of Tables 1, 2 and 3, of 40 CFR 503.13 is to ensure that heavy metals do not build up in the soil at farms, forest land, and land reclamation
sites to the point where the heavy metals become phytotoxic to plants. The permittee will be required to produce an information sheet (see Part III. C. of the permit) to be handed out
to all people who are receiving and land applying Class B biosolids to farms, ranches, and land reclamation sites (if biosolids are only applied to land owned by the permittee, the information
sheet requirements are waived). If the biosolids are land applied according to the regulations of 40 CFR 503.13, to any reasonable degree, the Class B biosolids will be able to be land
applied year after year, to the same farms, ranches, and land reclamation sites without any deleterious effects to the environment. Class B Requirements With Regards to Heavy Metals
If the biosolids are to be land applied to agricultural land, forest land, a public contact site or a reclamation site it must meet at all times:
The maximum heavy metals listed in 40 CFR Part 503.13(b) Table 1 and the heavy metals loading rates in40 CFR Part 503.13(b) Table 2; or
The maximum heavy metals in 40 CFR Part 503.13(b) Table 1 and the monthly heavy metals concentrations in 40 CFR Part 503.13(b) Table 3.

Class A Requirements for Home Lawn and Garden Use
If biosolids are land applied to home lawns and gardens, the biosolids need to be treated by a specific process to further reduce pathogens (PFRP), and meet a microbiological limit of
less than less than 3 most probable number (MPN) of Salmonella per 4 grams of total solids (or less than 1,000 most probable number (MPN/g) of fecal coliform per gram of total solids)
to be considered Class A biosolids. At this time CWWTFdoes not intend to distribute biosolids to the public for use on the lawn and garden and thus is not required meet Class A Biosolids
requirements currently.
Pathogens Class B
If biosolids are to be land applied for agriculture or land reclamation the solids need to be treated by a specific process to significantly reduce pathogens (PSRP). At this time CWWTFdoes
not intend to distribute bulk biosolids for land application and thus is not required meet Class B Biosolids requirements currently. If CWWTF intends to land apply in the future, they
will need to meet a specific PSRP, the Director must be informed at least thirty (30) days prior to its use. This change may be made without additional public notice.
Vector Attraction Reduction (VAR)
If the biosolids are land applied CWWTFwill be required to meet VAR through the use of a method of listed under 40 CFR 503.33. At this time CWWTFdoes not intend to distribute biosolids
to the public for beneficial use, and will be disposing of them in a landfill.If the CWWT intends to land apply in the future, they need to meet one of thelisted alternatives in 40 CFR
503.33, the Director must be informed at least thirty (30) days prior to itsuse. This change may be made without additional public notice.
Landfill Monitoring Under 40 CFR 258, the landfill monitoring requirements include a paint filter test to determine if the biosolids exhibit free liquid. If the biosolids do not pass
a paint filter test, the biosolids cannot be disposed in the sanitary landfill (40 CFR 258.28(c)(1).
Record Keeping
The record keeping requirements from 40 CFR 503.17 are included under Part III.G. of the permit. The amount of time the records must be maintained are dependent on the quality of the
biosolids in regards to the metals concentrations. If the biosolids continue to meet the metals limits of Table 3 of 40 CFR 503.13, and are sold or given away the records must be retained
for a minimum of five years. If the biosolids are disposed in a landfill the records must retained for a minimum of five years.
Reporting
CWWTFmust report annually as required in 40 CFR 503.18. This report is to include the results of all monitoring performed in accordance with Part III.B of the permit, information on
management practices, biosolids treatment, and certifications. This report is due no later than February 19 of each year. Each report is for the previous calendar year.
MONITORING DATA
METALS MONITORING DATA
Coalville does not have any categorical industrial contributors to the system and landfills all biosolids produced so the pathogen and pollutant monitoring requirements for the biosolids
has been removed from the permit. This may be re y have been granted the elimination of biosolids pollutant and The CWWTF is not required to monitor biosolids for pathogens and pollutants.
As a result of this, there is no monitoring data.
STORM WATER
Separate storm water permits may be required based on the types of activities occurring on site.
Industrial Storm Water Permit coverage under UPDES Permit UTR000000 is not required due to the facility having a design flow of less than 1 MGD. Storm Water permit provisions have been
removed from this UPDES permit as part of a programmatic separation of the previously combined UPDES Industrial permit.
Construction General Storm Water Permit under UPDES Permit UTRC00000 is required for any construction at the facility which disturbs an acre or more.
STORM WATER REQUIREMENTS
Due to the facility having a design flow of less than 1 MGD, the permittee is not required to maintain separate coverage or an appropriate exclusion under the Multi-Sector General Permit
(MSGP) for Storm Water Discharges Associated with Industrial Activities (UTR000000).
Separate permit coverage under the Construction General Storm Water Permit (CGP) may be required for any construction at the facility which disturbs an acre or more of land. A Notice
of Intent (NOI) is required to obtain a construction storm water permit prior to the period of construction. This can also be accomplished online at: https://deq.utah.gov/water-quality/general-construction-storm-water-updes-permits.
Information onstorm water permit requirements can be found at http://stormwater.utah.gov
PRETREATMENT REQUIREMENTS
The pretreatment requirements in the permit are to assist the Division of Water Quality (DWQ) in understanding the sources discharging to the Coalville Publicly Owned Treatment Works
(POTW). Coalville has not been designated for implementing an Approved POTW Pretreatment Program (Program). This is due to the flow through the plant being less than 1 MGD and a review
of the service area and UPDES Permit Application by DWQ. Based on this information, DWQ did not find any industrial discharges that are or could be Significant Industrial Users of the
Coalville POTW.
Coalville does not have to develop an Approved Program;however, any wastewater discharged to the CoalvillePOTW is subject to Federal, State and local regulations. Pursuant to Section
307 of the Clean Water Act, Coalville must comply with the permit to ensure DWQ can adequately control Industrial Dischargers to the Coalville POTW.
DWQ encourages Coalville to attend training regarding the Pretreatment Program. This will ensure Industrial Users are found and reported to DWQ. Which is a requirement regarding the
industrial waste survey (IWS) in Part II of the UPDES Permit. If an Industrial User begins to discharge or an existing Industrial User changes their discharge,Coalville must resubmit
an IWS within sixty days following the introduction or change as stated in Part II of the permit. Please contact the DWQ Pretreatment Coordinator for assistance in classifying an Industrial
User.
It is required that Coalville submit for review any Local Limits that are developed to DWQ for review. If local limits are developed, it is required that Coalvill perform an annual evaluation
of the need to revise or develop technically based local limits for pollutants of concern to implement the general and specific prohibitions 40 CFR, Part 403.5(a) and Part 403.5(b).
This evaluation may indicate that present local limits are sufficiently protective, need to be revised or should be developed.
BIOMONITORING REQUIREMENTS
A nationwide effort to control toxic discharges where effluent toxicity is an existing or potential concern is regulated in accordance with the Utah Pollutant Discharge Elimination System
Permit and Enforcement Guidance Document for Whole Effluent Toxicity Control (biomonitoring), dated February 2018. Authority to require effluent biomonitoring is provided in Permit
Conditions, UAC R317-8-4.2, Permit Provisions, UAC R317-8-5.3 and Water Quality Standards, UAC R317-2-5 and R317 -2-7.2.
The permittee is a minor municipal facility discharging less than 1MGD. Additionally, there is not enough information on the receiving water. Based on these considerations, there will
be no Whole Effluent Toxicity testing in this permit. The permit will contain toxicity reopener language.

the waste rightPerhaps the solution to a problem like one of these may lie in investigating the types and amounts of wastewater entering the sewer system from industrial users.An industrial
user (IU) is defined as a non-domestic user discharging to the waste treatment facility which meets any of the following criteria: 1.has a lot of process wastewater (5% of the flow
at the waste treatment facility or more than 25,000 gallons per work day.)Examples:Food processor, dairy, slaughterhouse, industrial laundry.2.is subject to Federal Categorical Pretreatment
Standards;Examples:metal plating, cleaning or coating of metals, blueing of metals, aluminum extruding, circuit board manufacturing, tanning animal skins, pesticide formulating or packaging,
and pharmaceutical manufacturing or packaging,3.is a concern to the POTW.Examples:septage hauler, restaurant and food service, car wash, hospital, photo lab, carpet cleaner, commercial
laundry.All users of the water treatment facility are prohibited from making the following types of discharges:1.A discharge which creates a fire or explosion hazard in the collection
system.2.A discharge which creates toxic gases, vapor or fumes in the collection system.3.A discharge of solids or thick liquids which creates flow obstructions in the collection system.4.An
acidic discharge (low pH) which causes corrosive damage to the collection system.5.Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will
cause problems in the collection system or at the waste treatment facility.6.Waste haulers are prohibited from discharging without permission. (No midnight dumping!)When the solution
to a sewer system problem may be found by investigating the types and amounts of wastewater entering the sewer system discharged from IUs, it’s appropriate to conduct an Industrial Waste
Survey.An Industrial Waste Survey consists of:Step 1: Identify Industrial UsersMake a list of all the commercial and industrial sewer connections.Sources for the list:business license,

REASONABLE POTENTIAL ANALYSIS
Water Quality has worked to improve our reasonable potential analysis (RP) for the inclusion of limits for parameters in the permit by using an EPA provided model. As a result of the
model, more parameters may be included in the renewal permit. A Copy of the Reasonable Potential Analysis Guidance (RP Guide) is available at water Quality. There are four outcomes
for the RP Analysis. They are;
Outcome A:A new effluent limitation will be placed in the permit.
Outcome B:No new effluent limitation. Routine monitoring requirements will be placed or increased from what they are in the permit,
Outcome C:No new effluent limitation. Routine monitoring requirements maintained as they are in the permit,
Outcome D:No limitation or routine monitoring requirements are in the permit.
A quantitative RP was not performed on effluent metals data because there is inadequate data for use in a RP. Additional monitoring for metals will be included in this permit to support
future RP.
