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 UPDEs permit 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 (POC) 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.
What are the designated uses of the receiving water (R317-2-6)?
†Domestic Water Supply
†Recreation
†Aquatic Life
†Agricultural Water Supply
†Great Salt Lake

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 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 –(Proceed to B3 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 B4 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.

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

Part X. Antidegradation Review continued
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.

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.

Jacob,
Everything looks great except Part VII, Pretreatment. The district doesn't have an approved pretreatment program, so the
first answer should be No, and the rest of the section needs to be answered.

need to submit those again.
