Current through Bulletin 2024-06, March 15, 2024
1.1. Scope of This Rule
A. General. This rule is intended to aid the
logical development, from feasibility study, through startup, to operation of a
wastewater collection, treatment and disposal project.
B. Authority. Construction and operating
permits and approvals are issued pursuant to the provisions of Sections
19-5-104,
19-5-107
and
19-5-108.
Violation of these permit(s) or approval(s) including compliance with the
conditions thereof, or beginning of construction, or modification without the
Director's approval, is subject to the penalties provided in Section
19-5-115.
C. Applicability
1. This rule applies to:
a. communities, sewerage agencies,
industries, and federal or state agencies (hereinafter referred to as the
applicant), and
b.
i. construction, installation, modification
or operation of any treatment works or part thereof or any extension or
addition thereto, or
ii.
construction, installation, modification or operation of any establishment or
any extension or modification or addition to it, the operation of which would
probably result in a discharge.
2. The applicant must not advertise the
project for bids and must not begin construction without receiving a
construction permit.
D.
Requirements
1. The design requirements in
this rule are for collection, treatment and disposal of wastewater largely
originating from domestic sources. These criteria are intended to be limiting
values for items upon which an evaluation of such plans and specifications will
be made and to establish, as far as practicable, uniformity of practice. This
rule also provides for a mechanism to apply water pollution control research
and recommendations for further evaluation by the design engineer.
2. Communities, and the engineering
profession should discuss with the staff of the Director possible combinations
of wastewater treatment and disposal processes or situations not covered in
detail by this rule.
E.
Construction Permit and Approvals
1. When a
Permit or an Approval is Issued. A construction permit or an approval is issued
when the applicant has met all requirements of this rule, including any
additional requirements of funding programs administered by the Director. The
applicant or the designee or the consultant should meet with the staff of the
Director to discuss the plan of study before undertaking extensive engineering
studies for construction of treatment works. A permit for construction of a new
treatment works or a sewerage system, or modifications to an existing treatment
works or sewerage system for multiple units under separate ownership will be
issued only if the treatment works or sewerage system are under the sponsorship
of a body politic as defined in
R317-1-1.
2. Variance. The Director may grant a
variance from the minimum requirements stated in this rule, subject to
site-specific consideration and justification, but not overriding safeguarding
of public health or protection of water quality or engineering practice. The
applicant must submit pertinent and relevant material in support of a variance
from the minimum requirements.
3.
Limitations
a. The issuance of a construction
permit does not relieve in any way the applicant of the obligation to obtain
other approvals and permits, i.e., ground water discharge permit, clearances
etc., from other agencies which may have jurisdiction over the
project.
b. The permit will expire
at the end of one year from the date of issuance if the approved project is not
under substantial construction. Plans and specifications must be resubmitted
for review and reissuance of the expired permit.

2. Facilities requiring operating permits
that treat domestic waste will typically be issued a general permit rather than
individual permits. General permits may be issued, modified, revoked and
reissued, or terminated in accordance with applicable requirements of

A. Construction-related Bypass. Operation of
all existing sewers, pump stations, and treatment plants must continue without
interruption during the construction of new facilities or modification of
existing facilities. Therefore, bypassing will not be allowed except under
extenuating circumstances. If this is not possible and construction will result
in the discharge of partially treated and untreated sewage into the surface
waters of the state, an approval for such a discharge shall be required from
the Director before such discharge occurs.
B. Request for a Construction-related Bypass.
A formal request for the consideration of a construction-related bypass shall
be submitted to the Director by the permittee not less than 90 days prior to
the date of proposed bypass initiation. Such request shall contain at least the
following information:

description of the construction work to be performed which the owner has deemed
warrants a bypass;
2. an analysis
of all known alternatives which would eliminate or reduce the need for plant
bypassing;
3. cost-benefit and
effective analysis of alternatives, including an assessment of resource
damages;
4. the minimum and maximum
duration of bypassing under each alternative;
5. the applicant's preferred alternative for
conducting the bypass;
6. the
projected date of initiation of bypass.
C. Approval or Denial of a
Construction-related Bypass
1. The request
for a construction-related bypass will be approved or denied following a
thorough review with due consideration of compliance with the discharge
permit(s); water quality standards; and all known available and reasonable
methods to abate water pollution.
2. An approval issued to permit bypass will
contain all restrictions necessary to minimize the duration of bypassing. A
denial determination will state the reasons for the denial and will direct the
permittee to initiate a plan of action to implement an alternative to
bypassing.
1.12. Innovative Processes Evaluation
A. Basic requirements. The Director will
consider the evaluation of innovative approaches to wastewater treatment in the
interest of encouraging advances in technology, processes, equipment and
material not covered by this rule, provided that:
1. a favorable recommendation has been made
by a professional engineer licensed to practice in Utah, following his own
evaluation of developmental processes or equipment or material, for a specific
project;
2. the applicant has
capital and technical resources to replace or modify developmental processes,
equipment and material with conventional processes, equipment and
material;
3. the risk incurred with
the experimentation rests solely with the proponent of processes, equipment and
material as evidenced by the written acknowledgement to the Director;
and
4. the applicant will replace
the failed processes, equipment and material with a proven conventional
processes, equipment and material as evidenced by the written acknowledgement
to the Director.
B.
Approval Limitations
1. The Director may
approve developmental processes, equipment and material may be approved in the
form of terms and conditions to a construction permit, when reliable operating
data from full scale installations are not available. The term and conditions
may include such as, but not necessarily limited to, demonstration period for a
successful application, requirements to submit reports on the operation of the
system during the experimental period.
2. The Director may limit the number of
approvals for the same developmental processes, equipment and material until
reliable and valid operational experience is gained.
C. Evaluation Criteria. The evaluation of
innovative processes will include the following factors:
1. anticipated performance of the system in
full scale field conditions,
2.
ability to consistently meet required effluent and water quality
standards,
3. any evidence of
equivalence to conventional technology,
4. the owner's ability to finance, and to
operate and maintain the system with the level of expertise necessary,
and
5. submission of process
descriptions, schematics, reports, monitoring and performance data, costs,
specific studies, bench scale test data and pilot plant test data, and any
other information appropriate and necessary for the evaluation.
