Ariz. Admin. Code § R18-9-B201 - General Considerations And Prohibitions
A. Applicability. The requirements in this
Article apply to all sewage treatment facilities, including expansions of
existing sewage treatment facilities, that treat wastewater containing sewage,
unless the discharge is authorized by a general permit under Article 3 of this
Chapter.
B. The Director may
specify alert levels, discharge limitations, design specifications, and
operation and maintenance requirements in the permit that are based upon
information provided by the applicant and that meet the requirements under
A.R.S. §
49-243(B)(1).
C. The permittee shall ensure that a sewage
treatment facility is operated by a person certified under 18 A.A.C. 5, Article
1, for the grade of the facility.
D. Operation and maintenance.
1. The owner or operator shall maintain, at
the sewage treatment facility, an operation and maintenance manual for the
facility and shall update the manual as needed.
2. The owner or operator shall use the
operation and maintenance manual to guide facility operations to ensure
compliance with the terms of the Aquifer Protection Permit and to prevent any
environmental nuisance described under A.R.S. §
49-141(A).
3. The Director may specify adherence to any
operation or maintenance requirement as an Aquifer Protection Permit condition
to ensure that the terms of the Aquifer Protection Permit are met.
4. The owner or operator shall make the
operation and maintenance manual available to the Department upon
request.
E. A person
shall not create or maintain a connection between any part of a sewage
treatment facility and a potable water supply so that sewage or wastewater
contaminates a potable or public water supply. A person may only create and
maintain a connection between sewage treatment facilities, advanced water
treatment facilities, and a potable water supply under an Advanced Water
Purification permit issued pursuant to Article 8 of this Chapter.
F. A person shall not bypass or release
sewage or partially treated sewage that has not completed the treatment process
from a sewage treatment facility.
G. Reclaimed water dispensed to a direct
reuse site from a sewage treatment facility is regulated under Reclaimed Water
Quality Standards in 18 A.A.C. 11, Article 3.
H. The preparation, transport, or land
application of any biosolids generated by a sewage treatment facility is
regulated under 18 A.A.C. 9, Article 10.
I. The owner or operator of a sewage
treatment facility that is a new facility or undergoing a major modification
shall provide setbacks established in the following table. Setbacks are
measured from the noise or odor-producing treatment and disposal components
within the sewage treatment facility to the nearest property line of an
adjacent dwelling, workplace, or private property. If an owner or operator
cannot meet a setback for a facility undergoing a major modification that
incorporates full noise, odor, and aesthetic controls, the owner or operator
shall not further encroach into setback distances existing before the major
modification except as allowed in subsection (I)(2).

1. Full
noise, odor, and aesthetic controls means that:
a. Noise due to the sewage treatment facility
does not exceed 50 decibels at the facility property boundary on the A network
of a sound level meter or a level established in a local noise
ordinance,
b. All odor-producing
components of the sewage treatment facility are fully enclosed,
c. Odor scrubbers or other odor-control
devices are installed on all vents, and
d. Fencing aesthetically matched to the area
surrounding the facility.
2. The owner or operator of a sewage
treatment facility undergoing a major modification may decrease setbacks if:
a. Allowed by local ordinance; or
b. Setback waivers are obtained from affected
property owners in which the property owner acknowledges awareness of the
established setbacks, basic design of the sewage treatment facility, and the
potential for noise and odor.
J. The owner or operator of a sewage
treatment facility shall not operate the facility so that it emits an offensive
odor on a persistent basis beyond the setback distances specified in subsection
(I).
