refunded. The manner of the refund shall be determined by the Commission at the time a refund becomes
necessary.
(K) Fire Flow Requirements: In the event the applicant for service has fire flow requirements that
require additional facilities beyond those facilities whose costs were included in the off-site hook-up fee,
and which are contemplated to be constructed using the proceeds of the off-site hook-up Fee, the Company
may require the applicant to install such additional facilities as are required to meet those additional fire
flow requirements, as a non-refundable contribution, in addition to the off-site hook-up fee.

(D) Off-Site Facilities Construction by Developer: Company and Applicant, Developer, or Builder may
agree to construction of off-site facilities necessary to serve a particular development by Applicant,
Developer or Builder, which facilities are then conveyed to Company. In that event, Company shall credit
the total cost of such off-site facilities as an offset to off-site hook-up fees due under this Tariff. If the total
cost of the off-site facilities constructed by Applicant, Developer or Builder and conveyed to Company is
less than the applicable off-site hook-up fees under this Tariff, Applicant, Developer or Builder shall pay
the remaining amount of off-site hook-up fees owed hereunder. If the total cost of the off-site facilities

Builder is engaged in the development of a residential subdivision and/or development containing more
than 150 lots, the Company may, in its reasonable discretion, agree to payment of off-site hook-up fees in
installments. Such installments may be based on the residential subdivision and/or development's phasing
and should attempt to equitably apportion the payment of charges hereunder based on the Applicant's,
Developer's or Builder's construction schedule and water service requirements. In the alterative, the
Applicant, Developer, or Builder shall post an irrevocable letter of credit in favor of the Company in a
commercially reasonable form, which may be drawn by the Company consistent with the actual or planned
construction and hook up schedule for the subdivision and/or development.
(G) Off-Site Hook-Up Fees Non-refundable: The amounts collected by the Company pursuant to the
off-site facilities hook-up fee tariff shall be non-refundable contributions in aid of construction.

hook-up fees shall be deposited into a separate account and bear interest and shall be used solely for the
purposes of paying for the costs of installation of off-site facilities, including repayment of loans obtained
for the installation of off-site facilities.

INDUSTRIAL PRETREATMENT PROGRAM AND TARIFF
ADEQ Public Water System:
ADEQ Public Water System Number: 07-046
SECTION 1 - PRETREATMENT PROGRAM
1.0 INTRODUCTION
To control the discharge of pollutants to the Nation's waters, the Clean Water Act (CWA) requires the
Environmental Protection Agency (EPA) to promulgate regulations related to discharges. Discharges from
non-domestic dischargers can impact the operations of Water Reclamation Facilities (WRFs) and Publicly
Owned Treatment Works (POTWs) as the pollutants can pass through or interfere with the operations of
the plants, threaten worker's health and safety, or contaminate sludges. The WRFs and POTWs are
designed to treat domestic sewage. The non-domestic discharges are regulated by the National
Pretreatment Program. Industrial and commercial dischargers (known as IUs) are required to obtain
permits, or other control mechanisms to discharge wastewater to the POTW/WRF under the National
Pretreatment Program. EPA promulgated the General Pretreatment Regulations (Title 40 Code of Federal
Regulations (CFR) Section 403), which defines the National Pretreatment Program. The Arizona
Administrative Code (AAC R18-9-A905(A)(8)(b)) incorporates the General Pretreatment
Program/Regulations.
Liberty Utilities (Litchfield Park Water & Sewer) Corp. (hereinafter referred to as Liberty Utilities)
operates the Palm Valley Water Reclamation Facility (PVWRF) located at McDowell Road and Litchfield
Park Road and the Sarival Water Reclamation Facility (SWRF) located at Sarival Avenue and McDowell
Road. PVWRF can treat up to 6.9 million gallons per day (MGD) of wastewater and the SWRF can treat
up to 4.0 million gallons per day (MGD), collectively "Facilities." The Facilities are owned and operated
by Liberty Utilities and serve the Litchfield Park and Goodyear communities. Liberty Utilities can regulate
discharges from IUs for potential contaminants of concern to minimize impact on its POTW/WRF under
Liberty Utilities' Industrial Pretreatment Program Tariff.
The discharge of toxic and other harmful pollutants from IUs can be effectively controlled through a local
pretreatment program that is based on these regulations, structured to address specific local concerns, and
enforced through Liberty Utilities Industrial Pretreatment Program and Tariff

PART TWELVE
INDUSTRIAL PRETREATMENT PROGRAM AND TARIFF
The objective of a Pretreatment Program (the General Pretreatment Regulations of the Clean Water Act
(40 CFR, Part 403)) is to:
to promote consistent application of pretreatment requirements among customers and to maintain
the integrity of Liberty Utilities - PVWRF and SWRF so that the continuity of safe and reliable
service to all customers and the protection of the environment are preserved.
to prevent the introduction of pollutants into the POTW/WRF that will interfere with its operation.
to prevent the introduction of inadequately treated pollutants into the collection systems that will
pass through the POTW/WRF into the receiving waters, the atmosphere, and landfills, or otherwise
be incompatible with the POTW/WRF.
to protect both POTW/WRF personnel who may be affected by wastewater and sludge in the
course of their employment and the general public.
to promote reuse and recycling of industrial wastewater and sludge from the POTW/WRF.
to provide fees for the apportionment of the costs of operation, maintenance, and improvement of
the POTW/WRF.
to enable Liberty Utilities to comply with its AZPDES conditions, sludge use and disposal
requirements, and any other Federal or State laws to which the POTW/WRF is subject.
The Pretreatment Program and tariff document (collectively, Tariff) shall apply to all IUs Liberty Utilities
receiving service from Liberty Utilities. The Pretreatment Program sets forth uniform requirements for
industrial discharges into the WRaps, and also establishes a separate industrial discharge permit requirement
IUs. The Pretreatment Program includes the issuance of individual wastewater discharge permits, provides
monitoring, compliance, and enforcement activities, establishes administrative review procedures, requires
IUs reporting, and provides for the setting of fees for the apportionment of costs resulting from the program
established herein.

SECTION 2 - AUTHORITY
Pretreatment Requirements apply to POTWs/WRFs
Regulations under the Federal Water Pollution Control Act (also known as the Clean Water Act), require
POTWs/WRFs to develop a pretreatment program for any POTW/WRF (or combination of POTWs
operated by the same authority) with a total design flow greater than 5 million gallons per day (MGD)
within a single collection system and receive wastewater from Industrial Users pollutants which Pass
Through or may Interfere with the operation of the WRF, or are otherwise subject to Pretreatment Standards.
Libertv Utilities is a Water Management Utilitv Under Section 502(4) of the Clean Water Act
Section 208 of the Clean Water Act devolves regional water quality management Designated Planning
Agencies, or DPAs. In this case, the DPA is the Maricopa Association of Governments (MAG), and MAG
maintains a Section 208 Area-wide Water Quality Management Plan (the MAG 208 Plan) detailing the
management of wastewater, recycled water and biosolids within Maricopa County.
DPAs engage other agencies for the management and execution of the short- and long-term strategies of
the DPA. These agencies arc Designated Management Agencies (DMAs) and Wastewater Management
Utilities (WMUs). While a DMA and a WMU perform the same functions, they are organizationally
different: DMAs are governmental entities, WMUs are public service corporations.
A DMA is defined as "a local government subdivision that is certified by ADEQ as having adequate
resources and capabilities to design, operate, and maintain wastewater facilities and the desire to implement
portions of the MAG 208 Plan." A WMU is "a privately-owned centralized wastewater treatment facility
and a collection system that provides services to multiple properties. To be a WMU, ADEQ must certify
that the entity has the resources, capability, and desire to function as a DMA." In addition, to be established
as a WMU, the private entity must provide a 20-year future growth plan and coordinate with neighboring
DMAs and other WMUs that will implement other strategies in the MAG 208 Plan.

Samples collected to satisfy reporting requirements must be based on data obtained through
appropriate sampling and analysis performed during the period covered by the report, based on data
that is representative of conditions occurring during the reporting period.
A. Except as indicated in Section B and C below, the IU must collect wastewater samples
using 24-hour flow proportional composite sampling techniques, unless time proportional
composite sampling or grab sampling is authorized by Liberty Utilities. Where time
proportional composite sampling or grab sampling is authorized by Liberty Utilities, the
samples must be representative of the discharge. Using protocols (including appropriate
preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab
samples collected during a 24-hour period may be composited prior to the analysis as
follows: for cyanide, total phenols, and sulfides the samples may be composited in the
laboratory or in the field, for volatile organics and oil and grease, the samples may be
composited in the laboratory. Composite samples for other parameters unaffected by the
compositing procedures as documented in approved EPA methodologies may be
authorized by Liberty Utilities, as appropriate. In addition, grab samples may be required
to show compliance with Local Limits.
B. Samples for oil and grease, temperature, pH, cyanide, total phenols,sulfides, and volatile
organic compounds must be obtained using grab collection techniques.
C. For sampling required in support of baseline monitoring and 90 day compliance reports
required in Sections 7.7.2 and 7.7.3 of the Pretreatment Program (40 CFR 403. l2(b) and
(d)), a minimum of four (4) grab samples must be used for pH, cyanide, total phenols, oil
and grease, sulfide and volatile organic compounds for facilities for which historical
sampling data do not exist, for facilities for which historical sampling data are available,
Liberty Utilities may authorize a lower minimum. For the response required by paragraphs
Section 7.7.4 (40 CFR 403. l2(e) and 403. l2(h)), the IU is required to collect the number
of grab samples necessary to assess and assure compliance with applicable Pretreatment
Standards and Requirements.

B. An IU may allow any bypass to occur which does not cause Pretreatment Standards or Requirements
to be violated, but only if it also is for essential maintenance to assure efficient operation. These
emergency shutdowns are not subject to the provision of paragraphs (C) and (D) of this Section.
c . Shut Down Notifications
(1) If an IU knows in advance of the need for a bypass, it shall submit prior notice to Liberty Utilities
at least ten (10) days before the date of the emergency shut down, if possible.
(2) An IU shall submit oral notice to Liberty Utilities of an unanticipated emergency shutdown that
exceeds applicable Pretreatment Standards within twenty-four (24) hours from the time it becomes
aware of the emergency shut down. A written submission shall also be provided within five (5)
days of the time the IU becomes aware of the emergency shut down. The written submission shall
contain a description of the emergency shut down, its cause, the duration of the bypass,including
exact dates and times, and, if the emergency shut down has not been corrected, the anticipated
time it is expected to continue, and steps taken or planned to reduce, eliminate, and prevent
reoccurrence of the emergency shut down. Libcrty Utilities may waive the written report on a
case-by-case basis if the oral report has been received within twenty-four (24) hours.

violations(s) in accordance with A.A.C. R.l4-2-609.C, and requiring that the customer correct the
violation(s) within a specified period of time, perform such tasks as the Company determines are
necessary for the customer to correct the violations, or perform such tasks and submit such information
as is necessary for the Company to evaluate the extent of noncompliance or to determine appropriate
enforcement actions to be taken in conjunction with the applicable regulatory agencies. A copy of the

II. SUSPENSION OF SERVICE
If the customer does not cure the violation, or present a satisfactory plan of remediation to Company,
within the time specified in the Notice, then Company may suspend or disconnect wastewater treatment
service in accordance with A.A.C. R.l4-2-609.C.
In addition, the Company may suspend wastewater treatment service, in accordance with A.A.C. R.14-
2-609.B (without notice), when such suspension is necessary, in the opinion of the Company, in order
to stop an actual or threatened discharge which presents or may present an imminent or substantial
endangerment to the health or welfare of persons, to the environment, or causes the Company to violate
any condition of its aquifer protection permit, AZPDES discharge permit, or any applicable sludge
disposal regulations.
Any customer notified of an immediate suspension of the wastewater treatment service shall
immediately stop or eliminate the discharge. In the event of a failure of the customer to comply
voluntarily with the cease-and-desist request, the Company shall take such steps as deemed necessary,
including immediate severance of the sewer connection and/or immediate disconnection of the water
service, to prevent or minimize damage to the company's wastewater system or endangerment to any
individuals or the environment. Any action that results in the immediate suspension of service, or
disconnection, of a customer shall be reported to the Director of the Utilities Division of the Arizona
Corporation Commission and Maricopa County Environmental Services Department (MCESD) within
twenty-four (24) hours of the suspension or disconnection. Any reconnection of the affected customer
shall be in accordance with the Company's Tariff for which the customer must pay the cost of
disconnection and reconnection, plus the cost of parts and installation of an Elder valve (or similar
equipment) to allow for easier disconnection in the event of a repeated discharge offense by customer.
