Part X. Antidegradation Review
The objective of antidegradation rules and policies is to protect existing high quality waters and set forth a process
for determining where and how much degradation is allowable for socially and/or economically important reasons.
In accordance with Utah Administrative Code (UAC R317-2-3), an antidegradation review (ADR) is a permit
requirement for any project that will increase the level of pollutants in waters of the state. The rule outlines
requirements for both Level I and Level II ADRs, as well as public comment procedures. This review form is
intended to assist the applicant and Division of Water Quality (DWQ) staff in complying with the rule but is not a
substitute for the complete rule in R317-2-3.5. Additional details can be found in the Utah Antidegradation
Implementation Guidance and relevant sections of the guidance are cited in this review form.
ADRs should be among the first steps of an application for a UPDES permit because the review helps establish
treatment expectations. The level of effort and amount of information required for the ADR depends on the nature
of the project and the characteristics of the receiving water. To avoid unnecessary delays in permit issuance, DWQ
recommends that the process be initiated at least one year prior to the date a final approved permit is required.
DWQ will determine if the project will impair beneficial uses (Level I ADR) using information provided by the
applicant and whether a Level II ADR is required. The applicant is responsible for conducting the Level II ADR.
For the permit to be approved, the Level II ADR must document that all feasible measures have been undertaken to
minimize pollution for socially, environmentally or economically beneficial projects resulting in an increase in
pollution to waters of the state.
For permit requiring a Level II ADR, this antidegradation form must be completed and approved by DWQ before
any UPDE6permit can be issued. Typically, the ADR form is completed in an iterative manner in consultation
with DWQ. The applicant should first complete the statement of social, environmental and economic importance
(SEEI)in Section C and determine the parameters of concern (POCV) in Section D. Once the POCs are agreed
upon by DWQ, the alternatives analysis and selection of preferred alternative Section E can be conducted based on
minimizing degradation resulting from discharge of the POCs. Once the applicant and DWQ agree upon the
preferred alternative, the review is considered complete, and the form is submitted to DWQ.

Part X. Antidegradation Review continued
Effluent flow reviewed: typically, this should be the maximum daily discharge at the design capacity of the
facility. Exceptions should be noted.
What is the application for? (Check all that apply)
†A UPDES permit for a new facility, project, or outfall.
†A UPDES permit renewal with an expansion of modification of an existing wastewater treatment
works.
†A UPDES permit renewal requiring limits for a pollutant not covered by the previous permit and/or
an increase to existing permit limits.
†A UPDES permit renewal with no charges in facility operations.
Section B. Is a Level II ADR required?
This section of the form is intended to help applicants determine if a Level II ADR is required for specific
permitted activities. In addition, the Executive Secretary'LUHFWRU may require a Level II ADR for an
activity with the potential for major impact on the quality of waters of the state (R317-2-3.5a.1).
B1. The UPDES permit is new or is being renewed and the proposed effluent concentration and
loading limits are higher than the concentration and loading limits in the previous permit and any
previous antidegradation review(s).
†YES – (Proceed6NLSto % of the Form)
†NO – No Level II ADR is required and there is no need to proceed further with the review questions.
Continue to the Certification Statement and Signature page.
B2. Will any pollutants use assimilative capacity of the receiving water, i.e. do the pollutant
concentrations in the effluent exceed those in the receiving waters at critical conditions? For most
pollutants, effluent concentrations that are higher than the ambient concentrations require an
antidegradation review? For a few pollutants such as dissolved oxygen, and antidegradation review is
required if the effluent concentrations are less than the ambient concentrations in the receiving water.
(Section 3.3.3 of Implementation Guidance)
†YES – (Proceed to % of the Form)
†NO – No Level II ADR is required and there is no need to proceed further with the review questions.

B3. Are water quality impacts of the proposed project temporary and limited (Section 3.3.4 of
Implementation Guidance)?Proposed projects that will have temporary and limited effects on water quality
can be exempted form a Lev le II ADR.
†YES –Identify the reason used to justify this determination if B4.1 and proceed to Section G. No Level
II ADR is required.
†NO –A Level II ADR is required (Proceed to Section C)
B3.1 Complete this question only if the applicant is requesting a Level II review exclusion for
temporary and limited projects (See R317-2-3.5(b)(3) and R317-2-3.5(b)(4)). For projects requesting a
temporary and limited exclusion please indicate the factor(s) used to justify this determination (check
all that apply and provide details as appropriate) (Section 3.3.4 of Implementation Guidance):
†Water quality impacts will be temporary and related exclusively to sediment or turbidity and fish
spawning will not be impaired.
Factors to be considered in determining whether water quality impacts will be temporary and
limited:
a) The length of time during which water quality will be lowered:
b) The perfect change in ambient concentrations of pollutants:
c) Pollutants affected:
d) Likelihood for long-term water quality benefits:
e) Potential for any residual long-term influences on existing
uses:
f) Impairment of fish spawning, survival and development of
aquatic fauna excluding fish removal efforts:
Additional justification, as needed:

Level II ADR
Section C, D, E, and F of the form constitute the Level II ADR Review. The applicant must provide as much
detail as necessary for DWQ to perform the antidegradation review. Questions are provided for the
convenience of applicants; however, for more complex permits it may be more effective to provide the
required information in a separate report. Applicants that prefer a separate report should record the report
name here and proceed to Section G of the form.
Option Report Name:
Section C. Is the degradation from the project socially and economically necessary to accommodate
important social or economic development in the area in which the waters are located? The applicant
must provide as much detail as necessary for DWQ to concur that the project is socially and economically
necessary when answering the questions in the section. More information is available in Section 6.2 of the
Implementation Guidance.
C1. Describe the social and economic benefits that would be realized through the proposed project,
including the number and nature of jobs created and anticipated tax revenues.
C2. Describe any environmental benefits to be realized through implementation of the proposed
project.
C3. Describe any social and economic losses that may result from the project, including impacts to
recreation or commercial development.
C4. Summarize any supporting information from the affected communities on preserving assimilative
capacity to support future growth and development.
Attachment B - Supplement to the Antidegradation Review Form
Big West Oil, LLC currently employs approximately 594 employees. With an expanded
discharge, it will allow the facility to keep current operations viable. Increase in flow will also
improve the water quality discharge to the Northwest Oil Drain/Salt Lake Sewage Canal.
The increased effluent discharge will improve the water quality due to discharging
contaminants at a lower concentration than what's in the receiving water.
No anticipated social or economic losses as the receiving water protected only for
infrequent primary and secondary recreational uses. These uses will not be impacted.
Not applicable.

C5. Please describe any structures or equipment associated with the project that will be placed within
or adjacent to the receiving water.
C6. Will the discharge potentially impact a drinking water source, e.g., Class 1C waters? Depending
upon the locations of the discharge and its proximity to downstream drinking water diversions,
additional treatment or more stringent effluent limits or additional monitoring, beyond that which may
otherwise be required to meet minimum technology standards or in stream water quality standards,
may be required by the Director in order to adequately protect public health and the environment
(R317-2-3.5 d.).
†YES
†NO
Section D. Identify and rank (from increasing to decreasing potential threat to designated uses) the
parameters of concern. Parameters of concern are parameters in the effluent at concentrations greater than
ambient concentrations in the receiving water. The applicant is responsible for identifying parameter
concentrations in the effluent and DWQ will provide parameter concentrations for the receiving water. More
information is available in Section 3.3.3 of the Implementation Guidance.

Section E. Alternative Analysis Requirements of Level II Antidegradation Review. Level II ADRs
require the applicant to determine whether there are feasible less-degrading alternatives to the proposed
project. More information is available in Section 5.5 and 5.6 of the Implementation Guidance.
E1. The UPDES permit is being renewed without any changes to flow or concentrations. Alternative
treatment and discharge options including changes to operations and maintenance were considered
and compared to the current processes. NO economically feasible treatment or discharge alternatives
were identified that were not previously considered for any previous antigradation review(s).
†YES –(Proceed to Section F)
†NO or Does Not Apply (Proceed to E2)
E2. Attach as an appendix to this form a report that describes that following factors for all alternative
treatment options (see 1) a technical descriptions of the treatment process, including construction costs
and continued operation and maintenance expenses, 2) the mass and concentration of discharge
constituents, and 3) a description of the reliability of the system, including the frequency where
recurring operation and maintenance may lead to temporary increases in discharged pollutants. Most
of this information is typically available from a Facility Plan, if available.
Report Name:
E3. Describe the proposed method and cost of the baseline treatment alternative. The baseline
treatment alternative is the minimum treatment required to meet water quality based effluent limits
(WQBEL) as determined by the preliminary or final wasteload analysis (WLC) and any secondary or
categorical effluent limits.

1 Introduction
This document is a supplement to the Utah Division of Water Quality (DWQ) Antidegradation Review
Form. Headings in this document correspond to question prompts in Part C through Part F of the form.
Instructions from the Antidegradation Form are italicized.
BWO is a petroleum refinery located in Davis County that processes approximately 36,000 barrels per
day of refinery throughput, producing primarily gasoline and diesel fuel. Products from the process units
are transferred to storage tanks in advance of further processing or blending before distribution to
markets via pipeline, rail cars, and transport trucks. BWO operations create refinery, distribution, and
related service-sector jobs as well as indirectly support the local and regional economy through
increasing the demand for refinery goods and services.
As described in the associated renewal application for Utah Pollutant Discharge Elimination System
(UPDES) Permit Number UT0026174, Big West Oil, LLC (BWO) is requesting an increase to the
maximum monthly average discharge to the Northwest Oil Drain to the Salt Lake Sewage Canal from
0.12 million gallons per day (MGD) to 0.33 MGD and the daily maximum discharge from 0.33 MGD to
0.55 MGD.
Well water is used in the Reverse Osmosis (RO) units, and RO reject water drains to Outfall 001. City
water is used in the refinery utility water system and the fire water system, which drains to the Utility Box
and ultimately to Outfall 001. The Process Flow Diagram (PFD) of Outfall 001 can be found in Attachment
F. The additional discharge would be managed within this process.

2 Part C. Is the degradation from the project socially and
economically necessary to accommodate important social
or economic development in the area in which the waters
are located?
The applicant must provide as much detail as necessary for DWQ to concur that the project is socially
and economically necessary when answering the questions in this section. More information is available
in Section 6.2 of the Implementation Guidance.
2.1 C1. Describe the social and economic benefits that would be realized
through the proposed project, including the number and nature of jobs
created and anticipated tax revenues.
Discharge from BWO is necessary to provide workers safe, reliable operating conditions and for the
refinery to remain operationally viable. BWO needs an increase in discharge quantity to manage ancillary
equipment safely. Since workers are the refinery’s most valuable asset, ensuring worker safety is a critical
economic and social benefit.
Because the refinery is located in Davis County, it is assumed that this county receives most of the
economic benefits associated with the refinery. The county population in 2024 was 378,470, which grew
approximately 1.04% from the population level in 2020 (362,695). BWO employs approximately 594
employees. Wages paid by the refinery industry are an important component of Davis County’s economy.
Contributing to these rural economies in turn provides a social benefit to residents of Davis County.

Further, the BWO refinery provides important social and economic benefits on a regional/national scale
by supplying fuel for domestic energy.
2.2 C2. Describe any environmental benefits to be realized through
implementation of the proposed project.
The continued water discharge to the Salt Lake Sewage Canal and into the Northwest Drain Canal
provides an important supplement to natural stream flows. The discharge provides water of a suitable
quantity and quality to support riparian vegetation, which in turn supports a diversity of aquatic, avian,
reptilian, and mammalian species. The discharge also supports the stream designated as a Class 2B, 3E,
and 5D.
2.3 C3. Describe any social and economic losses that may result from the
project, including impacts to recreation or commercial development.
This is a proposed increase of an existing discharge. No impacts are projected.
2.4 C4. Summarize any supporting information from the affected
communities on preserving assimilative capacity to support future
growth and development.

3

The communities in Davis County, which are the primary economic beneficiaries of the continued
operations at the BWO Refinery, would not be affected by the Northwest Drain Canal’s assimilative
capacity related to the refinery discharge.
The discharge, through compliance with applicable UPDES Permit effluent limits, will continue to be of
sufficient quality to support the attainment of the water body's designated beneficial uses, which in turn
will support any future growth in irrigation or agricultural use of the water body.
2.4 C5. Please describe any structures or equipment associated with the
project that will be placed within or adjacent to the receiving water.
No new structures will be placed within or adjacent to the receiving water.

4

3 Part D. Identify and rank (from increasing to decreasing
potential threat to designated uses) the parameters of concern.
Parameters of concern are parameters in the effluent at concentrations greater than ambient
concentrations in the receiving water. The applicant is responsible for identifying parameter
concentrations in the effluent and DWQ will provide parameter concentrations for the receiving water.
More information is available in Section 3.3.3 of the Implementation Guidance.

Only one pollutant of concern was identified in the current reverse osmosis discharge quality to the
Northwest Oil Drain/Salt Lake Sewage Canal (NWOD). This is identified in Table 1.

4 Part E. Alternative Analysis Requirements of a Level II
Antidegradation Review

Level II ADRs require the applicant to determine whether there are feasible less-degrading alternatives to
the proposed project. For new and expanded discharges, the Alternatives Analysis must be prepared
under the supervision of and stamped by a Professional Engineer registered with the State of Utah. DWQ
may grant an exception from this requirement under certain circumstances, such as the alternatives
considered potentially feasible do not include engineered treatment alternatives. More information
regarding the requirements for the Alternatives analysis is available in Section 5 of the Implementation
Guidance.

4.1 E1. The UPDES permit is being renewed with or without any changes
to flow or concentrations. Alternative treatment and discharge options
including changes to operations and maintenance were considered
and compared to the current processes. No economically feasible
treatment or discharge alternatives were identified that were not
previously considered for any previous antidegradation review(s).

Does not apply.

4.2 E2. Attach as an appendix to this form a report that describes the
following factors for all alternative treatment options: 1) a technical
description of the treatment process, including construction costs and
continued operation and maintenance expenses, 2) the mass and
concentration of discharge constituents, and 3) a description of the
reliability of the system, including the frequency where recurring
operation and maintenance may lead to temporary increases in
discharged pollutants. Most of this information is typically available
from a Facility Plan, if available.

Reject water generated during reverse osmosis does not require any additional treatment prior to
discharge.

6

4.3 E3. Describe the proposed method and cost of the baseline treatment
alternative. The baseline treatment alternative is the minimum
treatment required to meet water quality based effluent limits (WQBEL)
as determined by the preliminary or final wasteload analysis and any
secondary or categorical effluent limits.

BWO currently discharges to the Northwest Oil Drain. The baseline treatment alternative is improving the
operational and management of existing systems. Refer to Appendix A for additional information on the
Waste Load Allocation.

4.4 E4. Were any of the following alternatives feasible and affordable?

4.5 E5. From the applicant’s perspective, what is the preferred treatment
option?
The preferred treatment option is the increase of discharge water through improvements in the operations
and management of existing treatment systems.

Alternative Feasible Reason Not Feasible/Affordable
Pollutant Trading No Pollutant trading is not feasible at the point of discharge.
Water Recycling/Reuse No
Water is currently reused for dust control on all appropriate
surfaces and at all appropriate times. There are no feasible
means of increasing this use.
Land Application No Land application would require additional acreage to dispose
of the water. No additional land is available for application. .
Connection to Other Facility No BWO does not want to increase its discharge to the South
Davis Sanitary Sewer District.
Upgrade to Existing Facility No
Due to numerous permitting, engineering, and construction
difficulties, coupled with the high estimated cost for the facility
upgrade, this alternative is economically infeasible.
Total Containment No
This alternative would involve constructing unlined evaporation
ponds into which the water would be discharged. While
technically feasible, this option would have a large surface
impact and a relatively high construction cost. Additionally, the
water would still need to be discharged via Outfall 001.
Improved O&M of Existing Systems Yes
Seasonal or Controlled Discharge No Discharge flows year-round, making seasonal or controlled
discharges not an option.
New Construction No In addition to being cost-prohibitive, new construction would
require substantial power and be maintenance-intensive.
No Discharge No BWO cannot operate safely without discharge.

7

4.6 E6. Is the preferred option also the least polluting feasible alternative?
Yes, a controlled discharge from Outfall 001 is the least polluting feasible alternative.

8

5 Part F. Optional Information
5.1 F1. Does the applicant want to conduct optional public review(s) in
addition to the mandatory public review? Level II ADRs are public
noticed for a thirty day comment period. More information is available
in Section 3.7.1 of the Implementation Guidance.
No
5.2 F2. Does the project include an optional mitigation plan to compensate
for the proposed water quality degradation?
No

SUBJECT: Big West Oil Waste Load Allocation, Outfall 001

Receiving Water and Designated Uses (UAC R317-2-13):
Outfall 001 discharges to an unnamed drainage ditch to the Salt Lake City Sewage Canal/Northwest
Oil Drain (NWOD) and then into Farmington Bay of Great Salt Lake. In accordance with the Utah
Administrative Code (UAC) R317-2-13, the unnamed drainage ditch and NWOD are classified as
2B and 3E and Farmington Bay, Great Salt Lake is classified as 5D.

Class 2B Protected for infrequent primary and secondary contact recreation.

Class 3E Severely habitat-limited waters. Narrative standards will be applied to protect
these waters for aquatic wildlife.

Class 5D Farmington Bay of the Great Salt Lake. Protected for infrequent primary and
secondary contact recreation, waterfowl, shore birds and other water-oriented
wildlife including their necessary food chain.

Level I Antidegradation Review
The objective of the Level I Antidegradation Review (ADR) is to ensure the protection of existing
uses, defined as the beneficial uses attained in the receiving water on or after November 28, 1975.
For this facility, the Level I ADR was conducted in accordance with the Interim Methods for
Evaluating Use Support for Great Salt Lake Utah Pollution Discharge Elimination System
(UPDES) Permits. A Level II ADR is based on the requirements of UAC R317-2-3 and is not
required for this facility.

Whole Effluent Toxicity (WET) Requirements
The whole effluent toxicity (WET) requirements are based on the Utah Pollutant Discharge
Elimination System Permit and Enforcement Guidance Document for Whole Effluent Toxicity
(DWQ, February, 2018). As described in the Interim Methods, effluent pollutant concentrations are
screened against Class 3D aquatic life numeric criteria to determine reasonable potential ensuring
protection of the designated uses of the receiving waters.

Only inorganic pollutants are considered because the source of the effluent is deep groundwater
(>500’). Consistent with the other facilities discharging to NWOD, acute criteria are applied for the
NWOD and acute and chronic criteria are applied at the downstream discharge to Farmington Bay.
The approach was simplified to meeting the acute and chronic screening criteria in the NWOD
because of the relatively low effluent flows (Table 1).

The source of upstream flows in the NWOD are Warm Springs, the Salt Lake City Water
Reclamation Facility (SLCWRF), the Chevron Refinery, and stormwaters. The data for flows in the
NWOD are based on the Northwest Oil Drain and Salt Lake Sewage Canal Selenium, Ammonia and
Flow Characterization Report (Stantec, May 10, 2018) (NWOD Report). The SLCWRF is the
source of the majority of flow upstream of Big West Oil Outfall 001. Because the source of the most
of the water is the SLCWRF effluent, ambient pollutant concentrations in the NWOD are based on
concentrations measured in the SLCWRF effluent. These concentrations are reported in Table 1 of
the January, 2014 Final Salt Lake City Water Reclamation Facility Effluent Screening Summary
Report.

The maximum allowable acute and chronic pollutant concentrations in the Big West Oil effluent
are estimated using the minimum flow reported in the NWOD Report for the “Downstream of
Chevron Outfall” monitoring location. The maximum concentrations for the SLCWRF effluent are
derived from the long-term monitoring location (SALT LAKE CITY WWTP,4991250) for the
period 2014-2024. The Big West Oil allowable effluent concentrations for copper, chromium, and
mercury concentrations are based on the chronic criteria because NWOD concentrations are at the
criteria under the limiting conditions assumed. Tables 1, 2, and 3 summarize the assumptions and
results.

Whole Effluent Toxicity (WET) Biomonitoring
WET biomonitoring requirements are based on the 2018 Utah Pollutant Discharge Elimination
System Permit and Enforcement Guidance Document for Whole Effluent Toxicity. The immediate
receiving waters are Class 3E, severely habitat limited and dilution of the effluent in the NWOD
(also Class 3E) exceeds 20:1 and effluent flows are less than 20 MGD. Under these conditions, no
specific modifications for Great Salt Lake are needed. Quarterly acute WET monitoring using
alternating species of Ceriodaphnia dubia and Pimephales promelas (fathead minnow) and the
standard permit language from Appendix A of the Utah WET guidance are recommended.
