City of Shafter Cross-Connection Control Management Plan (CCCMP) City of Shafter CCCMP – June 2025 2-4
Phase 3 – Residential Connections without Backflow Protection The City currently has, as of May 14, 2025, 4,489 residential connections without backflow protection installed at the meter. For those residential connections the City will assess each site by means of office-based tools such as:
 City will utilize GIS system, and have excel spreadsheets available to export, and create an attribute for Specialist to sign, per each physical address or every meter. The following will supplement:
o Reviewing sites via Google Maps or other aerial photography software. o Reviewing tract maps to review blocks of residential customer in a common building area or zone.
o Using meter route maps or other billing information databases.

The office-based assessment will review sites for:
 Private water wells
 Other auxiliary water supplies
 Sewer lift stations
 Graywater systems
 Pools
The office-based assessments would be conducted based on the available Cross-Connection Control Program Specialist hours to review the office-based databases and/or files.  If the Cross-Connection Control Program Specialist determines that based on the officebased assessment that an approved BPA is not required, they will note that in the assessment database.
 If the Cross-Connection Control Program Specialist determines that based on the officebased that an approved BPA is required, they will note that in the assessment database and notify the residential customer that an approved BPA must be installed at the meter connection and note that the customer has been contacted in the assessment database.

It is assumed that a Cross-Connection Control Program Specialist can perform assessments by means of office-based tools. Assuming that the total number of annual Cross-Connection Control Program Specialist available hours is 85 hours/yr [5% of total annual 1,704 hours (2,080 total annual work hours - 24 hours for Floating holidays - 96 hours for City holidays - 120 hours for vacation - 96 hours for sick time - 40 hours for jury duty)], and the Cross-Connection Control Program Specialist can review ten (10) sites per hour, therefore 850 residential sites can be assessed per year.

Based on the 4,489 residential connections without backflow protection installed at the meter, as of May 14, 2025, the City has determined that this phase of the assessments can be completed within five (5) years and three (3) months from the completion of Phase 2.

If necessary, the City will follow up with the residential customers.

4 Backflow Prevention
In accordance with the State CCCPH, Section 3.1.3 (a)(4) and Section 3.2.2 – the City must ensure that actual and potential cross-connections are eliminated when possible or controlled by the installation of approved BPAs or AG’s consistent with the requirements of the Article 3 of the State CCCPH and the sections to follow. The City has 575 backflow assemblies installed at the water connections, and 541 onsite backflow assembles which are in the City’s tracking database and included in their annual backflow testing reports.

4.1 Backflow Prevention Requirements
(a) The City must ensure its distribution system is protected from backflow from identified hazards through the proper installation, continued operation, and field testing of an approved BPA (see Section 4.2 for installation and approved BPA criteria). When a DC is required or referenced in the State CCCPH, a DCDA or DCDA-II type of assembly may be substituted if appropriate. When an RP is required or referenced in the State CCCPH, an RPDA or RPDA-II type of assembly may be substituted if appropriate. (b) The BPA installed must be no less protective than that which is commensurate with the degree of hazard at a user premises, as specified in this section and as determined based on the results of the hazard assessment conducted pursuant to CCCMP Section 3. (c) Unless specified otherwise in this section, a City must, at all times, protect its distribution system from high hazard cross-connections (see CCCMP Appendix E for examples), through premises containment, through the use of AG(s) or RP(s). (1) Following State Water Board review and approval, the City may implement an alternate method of premises containment in lieu of a required AG provided that the proposed alternative would provide at least the same level of protection to public health.
(2) Following State Water Board review and approval, the City may accept internal protection in lieu of containment when premises containment is not feasible. (d) Except as otherwise allowed or prohibited in statute or in CCR Title 22, Division 4, Chapter 3, a swivel-ell may be used instead of an AG for premises containment protection when temporarily substituting tertiary recycled water use areas with potable water from a PWS if all the following criteria are met:
(1) the swivel-ell is approved by the State Water Board; (2) the City has a cross-connection control program, required pursuant to the State CCCPH Section 3.1.3, and the use and operation of the swivel-ell is described in the CCCMP required pursuant to the State CCCPH Section 3.1.4; (3) the design and construction-related requirements of the swivel-ell adheres to the criteria in CCCPH Appendix C;

10 User Supervisors
In accordance with the State CCCPH, Section 3.2.2 (3)(f),The State Water Board and City may, at their discretion, require a water user to designate a user supervisor when the user premises has a multi-piping system that conveys various types of fluids and where changes in the piping system are frequently made. If a user supervisor is designated the following is required:
(1) The user supervisor is responsible for the avoidance of cross-connections during the installation, operation and maintenance of the water user’s pipelines and equipment. The user supervisor must be trained on the fluids used and backflow protection for the premise, and must inform the City of changes in piping, and maintain current contact information on file with the City; and
(2) The City must include in the CCCMP required in CCCPH Section 3.1.4 the training and qualification requirements for user supervisors if required by the State Water Board or City, identify the entity that will provide the user supervisor training, and frequency of any necessary recurring training. The training must adequately address the types of hazards and concerns typically found.

The City has not required any user supervisors for use sites within the City.

11 Backflow Prevention Assembly Testing and Reporting
In accordance with the State CCCPH, Section 3.1.3 (a)(6) – the City must ensure that each BPA required by the CCCMP to protect the City’s domestic water system is field tested. The City must develop and implement a procedure for ensuring all BPAs are field tested, inspected, and maintained and AG’s are inspected and maintained in accordance with the State CCCPH, Section 3.3.3.

1. All BPAs installed in the City in compliance with it CCCMP must be field tested following installation, repair, depressurization for winterizing, or permanent relocation. All required field testing must be performed by certified backflow prevention assembly tester.

2. BPAs must be field tested at least annually. The State CCCPH does not preclude the City, the State Water Board, or a local health agency from requiring more frequent field testing for premises with high hazard cross-connection or BPA at increased risk of testing failure.

3. Air-gap separations must be visually inspected at least annually by a certified backflow prevention assembly tester or certified as a Cross-Connection Control Program Specialist.

4. The City must receive passing field tests before providing continuous service to a water user with a newly installed BPA.

5. BPAs that fail the field test must be repaired or replaced within 30 days of notification of the failure by the City. Extensions may be allowed by the City if low hazard and customer is working with City to replace.

Backflow prevention assembly testers must notify the City within one day if a backflow incident or an unprotected cross-connection is observed at the BPA or prior to the user premises during field testing. The City will immediately investigate and discontinue service to the user premises if a backflow incident is confirmed, and water service will not be restored to that user premises until the City receives a confirmation of a passing BPA field test from a backflow prevention assembly tester and the assembly is protecting the City.

11.1 Backflow Testing Notification Process
For each BPA in the City’s water distribution system, an annual notice that the BPA must be tested in accordance with the CCCMP will be sent to the user by BSI via mail.

Upon receipt, the Owner will have 30 days to have the BPA tested by a certified backflow assembly tester, and the test results submitted to the City via BSI Online.

City of Shafter Cross-Connection Control Management Plan (CCCMP) City of Shafter CCCMP – June 2025 11-2
Each water user with a BPA on the service connection must comply with the following schedule in order to be in compliance with the CCCMP and continue to receive water service from the City.
 First notice – the first annual notice of BPA testing required is sent to the user. First notices are sent out by BSI to all premises with BPA via mail. Users then have 30 days to respond via BSI Online.
 Second notice – if not resolved after 30 days from the date the first notice was sent to the user; a second notice will be sent to the user by BSI via mail. Users then have 15 days to respond via BSI Online.
 Third notice– if not resolved after 15 days from the date the second notice was sent to the user; a third notice will be sent to the user by BSI via mail with a shutoff notice. How long to respond and how to respond (return mail, email, both?). Users then have 30 days to respond via BSI Online.
 Fourth notice – if not resolved after 30 days from the date the third notice was sent to the user; City staff will install a door hangar with 72 hours notice to turnoff.  Termination of water service – if the user fails to provide the required test results 72 hours after the final notice; the water service will be terminated.

11.2 Damaged, missing, or improperly installed backflow prevention assemblies.

In the event that a backflow prevention assembly is missing (or stolen), installed incorrectly, illegally modified, or tampered with, the City will notify the user that the BPA is missing (or stolen), installed incorrectly, illegally modified, or tampered with, and provide them 30 days to replace, repair, or re-install the BPA.

Although no written standard operating procedure exists, BPAs that fail the field test must be repaired or replaced within 30 days of notification of the failure by the City. Extensions may be allowed by the City if low hazard and customer is working with City to replace.

What is a Cross Connection?

City of Shafter Cross-Connection Control Management Plan (CCCMP) City of Shafter CCCMP – June 2025
Appendix A
Background on Backflow Protection and Cross-Connection Control A.1 What is a Cross-Connection?
A cross-connection is an interconnection between a potable water supply and a non- potable source via any actual or potential connection or structural arrangement between a PWS and any source or distribution system containing liquid, gas, or other substances not from an approved water supply. Bypass arrangements, jumper connections, removable sections, swivel or change-over devices and other temporary or permanent devices through which, or because of which backflow can occur are considered to be cross-connections.1 The State CCCPH includes acceptable installation criteria for swivel-ell and other types of backflow prevention assemblies (BPAs) to prevent backflow.

Backflow is the undesired or unintended reversal of flow of water and/or other liquids, gases, or other substances into a PWS’s distribution system or approved water supply.

The presence of a cross-connection represents a location in a distribution system through which backflow of contaminants or pollutants can occur. Backflow occurs when a non-potable source is at a greater pressure than the potable water distribution system. Backflow can occur from either backsiphonage or backpressure. Backsiphonage occurs when a non-potable source enters the drinking water supply due to negative (i.e., sub-atmospheric) distribution system pressure. Backpressure occurs when the pressure from a non-potable source exceeds the pressure in the potable water distribution system.

Backsiphonage may be caused by a variety of circumstances, such as main breaks, flushing, pump failure, or emergency firefighting water demand. Backpressure may occur when heating, cooling, waste disposal, or industrial manufacturing systems are connected to potable supplies and the pressure in the external system exceeds the pressure in the distribution system. Both situations act to change the direction of water, which normally flows from the distribution system to the customer, so that non-potable substances from industrial, commercial, or residential premises flows back into the distribution system through a cross-connection.

Cross-connections are not limited to industrial or commercial facilities. Submerged inlets are found on many common plumbing fixtures and are sometimes necessary features of the fixtures if they are to function properly. Examples of this type of design are siphon-jet urinals or water closets, flushing rim slop sinks, and dental cuspidors.

Older bathtubs and lavatories may have supply inlets below the flood level rims, but modern sanitary design has minimized or eliminated this cross-connection in new fixtures. Chemical and industrial process vats sometimes have submerged inlets where the water pressure is used as an aid in diffusion, dispersion, and agitation of the vat contents. Even though a supply pipe may be installed above a vat, backsiphonage can still occur. Siphon action has been shown to raise a liquid in a pipe such as water almost 34 feet. Some submerged inlets are difficult to control, including those which are not apparent until a significant change in water level occurs or where

City of Shafter Cross-Connection Control Management Plan (CCCMP) City of Shafter CCCMP – June 2025
a supply may be conveniently extended below the liquid surface by means of a hose or auxiliary piping. A submerged inlet may be created in numerous ways, and its detection may be difficult.

Chemical and biological contaminants have caused illness and deaths during known incidents of backflow, with contamination affecting several service connections, and the number of incidents reported is believed to be a small percentage of the total number of backflow incidents that actually occur. The public health risk from cross-connections and backflow is a function of a variety of factors including cross-connection and backflow occurrence and type and amount of contaminants.

A.2 Purpose of a Cross-Connection Control Program
The purpose of a cross-connection control program is to prevent the occurrence of backflow into a PWS’s distribution system in order to protect customers from contamination or pollution from any on-site hazards. Properly installed and maintained BPAs, devices or methods provide protection against the threat posed by many conditions typically found on a user’s premise.

The use of approved BPAs ensures that the appropriate performance evaluation of the assembly was conducted. It is important and required by the State CCCPH to select and properly install an approved BPA that is capable of protecting the distribution system from the hazard identified.

The success of a program depends on individuals that are knowledgeable about crossconnection control to identify actual and potential hazards, apply principles of backflow protection and prevention, and implement cross-connection control policies and procedures. A successful program will have ongoing surveillance of a PWS to ensure BPAs, devices or methods are working and identify new hazards or changes in the distribution system. Certified specialists are needed to properly evaluate the degree of hazard that exists in the distribution system. Hazards typically identified in distribution systems along with the required level of protection are specified in Chapter 3 of the State CCCPH.

A.3 Notes on Applicability of the Cross-Connection Control Policy Handbook The State CCCPH provides the basis for regulating the use and management of crossconnection control programs and BPAs in PWSs, and related requirements for supporting programs and policies. Activities or uses outside of the scope of the authority of the State Water Board to regulate PWSs are not regulated by the State CCCPH, including California Plumbing Code requirements and definitions not related to PWSs.

Recycled water cross-connection control installations and programs for the purposes of protecting the recycled water supply are not regulated by the State CCCPH, although a PWS that uses recycled water is regulated by the State CCCPH to ensure that a PWS’s drinking water system has adequate backflow protection from a recycled water system.

Water systems that do not meet the definition of a PWS (e.g., “State Small Water Systems” under CCR Title 22, Article 3) are not regulated by the CCCPH, although they may need to comply with the California Plumbing Code, local health agencies, and other laws or entities. __________________________________________

Assembly Bill No. 1671
CHAPTER 533
An act to amend Section 116810 of, and to add Sections 116407 and 116555.5 to, the Health and Safety Code, relating to drinking water. [Approved by Governor October 6, 2017. Filed with Secretary of State October 6, 2017.]
legislative counsel’s digest
AB 1671, Caballero. Backflow protection and cross-connection controls:
standards.
(1) Existing law, the California Safe Drinking Water Act, requires the State Water Resources Control Board to administer provisions relating to the regulation of drinking water to protect public health, including, but not limited to, conducting research, studies, and demonstration projects relating to the provision of a dependable, safe supply of drinking water, enforcing the federal Safe Drinking Water Act, adopting regulations, and conducting studies and investigations to assess the quality of private domestic water wells. Existing law makes certain violations of the act a misdemeanor.

Existing law requires any person who owns a public water system to ensure that the system does certain things, including, but not limited to, that it will not be subject to backflow under normal operating conditions. Existing law, to ensure that testing and maintenance of backflow prevention devices are performed by persons qualified to do testing and maintenance, authorizes local health officers to maintain programs for certification of backflow prevention device testers and requires the certification program to be consistent with backflow protection regulations adopted by the state board. A violation of these provisions, or an order by a local health officer pursuant to these provisions, is a misdemeanor.

This bill would require a public water system to implement a crossconnection control program that complies with, and would require the certification program to be consistent with, applicable regulations and the standards described in (2).
(2) Existing regulations establish standards for a backflow prevention device and cross-connection control.

This bill, on or before January 1, 2020, would require the state board to adopt standards for backflow protection and cross-connection control and would authorize the state board to do so through the adoption of a policy handbook, as specified. By authorizing the state board to adopt standards, the violation of which would be a crime, the bill would create a new crime and impose a state-mandated local program.

(3) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that no reimbursement is required by this act for a specified reason.

The people of the State of California do enact as follows:

SECTION 1. Section 116407 is added to the Health and Safety Code, to read:
116407. (a) On or before January 1, 2020, the state board shall adopt standards for backflow protection and cross-connection control.
(b) The state board may implement subdivision (a) through the adoption of a policy handbook that is not subject to the requirements of Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code. The policy handbook shall include standards for backflow protection and cross-connection control. In developing the standards and any amendments to those standards, the state board shall consult with state and local agencies and other persons whom the state board has identified as having expertise in the subject of backflow protection and cross-connection control.

The state board shall hold at least two public hearings before adopting the policy handbook. The policy handbook shall be posted on the board’s Internet Web site. (c) (1) Upon the effective date of a policy handbook adopted by the state board pursuant to subdivision (b), the regulations set forth in Article 1 (commencing with Section 7583) and Article 2 (commencing with Section 7601) of Group 4 of Subchapter 1 of Chapter 5 of Division 1 of Title 17 of the California Code of Regulations shall become inoperative, and, 90 days thereafter, are repealed, unless the state board makes a determination not to repeal a specific regulation. (2) If the state board determines not to repeal a specific regulation pursuant to paragraph (1), the state board shall provide to the Office of Administrative Law and the Secretary of State written notice of its determination, including identification of the specific regulation that is not repealed. That regulation, upon the provision of that written notice to the Office of Administrative Law and the Secretary of State, shall become operative.

SEC. 2. Section 116555.5 is added to the Health and Safety Code, to read:
116555.5. A public water system shall implement a cross-connection control program that complies with applicable regulations and with standards adopted by the board pursuant to Section 116407.

SEC. 3. Section 116810 of the Health and Safety Code is amended to read:
116810. To ensure that testing and maintenance of backflow prevention devices are performed by persons qualified to do testing and maintenance, 94

City of Shafter Cross-Connection Control Management Plan (CCCMP) City of Shafter CCCMP – June 2025
— 3 — Ch. 533
local health officers may maintain programs for certification of backflow prevention device testers. The local health officer may suspend, revoke, or refuse to renew the certificate of a tester, if, after a hearing before the local health officer or his or her designee, the local health officer or his or her designee finds that the tester has practiced fraud or deception or has displayed gross negligence or misconduct in the performance of his or her duties as a certified backflow prevention device tester. The local health officer may collect fees from certified testers to offset the cost of the certification program provided pursuant to this section. The certification standards shall be consistent with standards adopted by the state board pursuant to Section 116407 and any other applicable backflow protection regulations.

SEC. 4. No reimbursement is required by this act pursuant to Section 6 of Article XIII B of the California Constitution because the only costs that may be incurred by a local agency or school district will be incurred because this act creates a new crime or infraction, eliminates a crime or infraction, or changes the penalty for a crime or infraction, within the meaning of Section 17556 of the Government Code, or changes the definition of a crime within the meaning of Section 6 of Article XIII B of the California Constitution.

13.04.080 Backflow prevention devices—Required—Type.

The type of protective device required under Section 13.04.070(A), (B) and (C) shall depend upon the degree of hazard which exists as follows:

A. In the case of any premises where there is an auxiliary water supply as stated in Section 13.04.070(A), (B) and (C) and it is not subject to any of the following rules, the city water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention device.

B. In the case of any premises where there is water or substance that would be objectionable but not hazardous to health, if introduced into the city water system, the city water system shall be protected by an approved double check valve assembly.

C. In the case of any premises where there is any material dangerous to health which is handled in such a fashion as to create an actual or potential hazard to the city water system, the city water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention device. Examples of premises where these conditions will exist include sewage treatment plants, sewage pumping stations, chemical manufacturing plants, hospitals, mortuaries and plating plants.

D. In the case of any premises where there are uncontrolled cross-connections, either actual or potential, the city water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention device at the service connection.

E. In the case of any premises where, because of security requirements or other prohibitions or restrictions it is impossible or impractical to make a complete cross-connection survey or hazard assessment, the city water system shall be protected against backflow or back-siphonage from the premises by the installation of a backflow prevention device in the service line. In this case, maximum protection will be required; that is, an approved air-gap separation or an approved reduced pressure principle backflow prevention device shall be installed in each service to the premises.

Title 13 - PUBLIC SERVICES
Chapter 13.04 - WATER SERVICE
Article II. Control of Backflow and Cross-Connections
Shafter, California, Code of Ordinances Created: 2025-04-02 08:09:26 [EST] (Supp. No. 23, Update 1)

Article II. Control of Backflow and Cross-Connections

13.04.020 Purpose.

The purpose of this article is:

A. To protect the public potable water supply of the city from the possibility of contamination or pollution by isolating within its customers' internal distribution system(s) or its customers' internal distribution system(s) or its customers' private water system(s) such contaminants or pollutants which could backflow or back-siphon into the public water supply system; and B. To promote the elimination or control of existing cross-connections, actual or potential, between its customers' in-plant potable water system(s) and nonpotable water systems, plumbing fixtures and industrial piping systems; and
C. To provide for the maintenance of a continuing program of cross-connections control which will systematically and effectively prevent the contamination or pollution of all potable water systems.

D. To comply with the State Water Resources Control Board’s Cross-Connection Control Policy Handbook (“CCCPH”). To the extent that any provision within this chapter conflicts with the CCCPH, as may be amended from time to time, the CCCPH shall control.
(Ord. XXX § 1, 2025; Ord. 376 § 1 (part), 1988: prior code § 4-10(6-7.01 (a)))

13.04.030 Definitions.

Except as otherwise specified herein, the terms used in this chapter shall have the meanings ascribed to them in Section 3.1.1. of the CCCPH.

A. “Director” shall refer to the director of public works for the city of Shafter or his designee. (Ord. XXX § 1, 2025; Ord. 376 § 1 (part), 1988: prior code § 10-4(6-7.02(b)—(t)))

13.04.040 Makeup of water system.

A. The water system shall be considered as made up of two parts:

1. The city system; and

2. The customer system.

B. The city system shall consist of the source facilities and the distribution system; and shall include all those facilities of the water system under the complete control of the city up to the point where the customer's system begins.

C. The source shall include all components of the facilities utilized in the production, treatment, storage and delivery of water to the distribution system.

D. The distribution system shall include the network of conduits used for the delivery of water from the source to the customer's system.

Created: 2025-04-02 08:09:26 [EST]
(Supp. No. 23, Update 1)

E. The customer's system shall include those parts of the facilities beyond the termination of the city distribution system which are utilized in conveying city delivered domestic water to points of use. (Ord. 376 § 1 (part), 1988: prior code § 4-10(6-7.03))

13.04.050 Water service connection—Installation and maintenance.

No water service connection to any premises shall be installed or maintained unless the water supply is protected as required by state laws and regulation and this article. Service of water to any premises shall be discontinued if a prevention device required by this article is not installed, tested and maintained, or if it is found that a backflow prevention device has been removed, bypassed, or if an unprotected cross-connection exists on the premises. Service will not be restored until such conditions or defects are corrected. (Ord. 376 § 1 (part), 1988: prior code § 4-10(6-7.04))

13.04.060 Inspection of customer's system.

The customer's system should be open for inspection at all reasonable times to authorized representatives of the public works water division to determine whether cross-connections or other structural or sanitary hazards, including violations of these regulations, exist. When such a condition becomes known, the director shall deny or immediately discontinue service to the premises by providing for a physical break in the service line until the customer has corrected the condition(s) in conformance with state and city statutes relating to plumbing and water supplies and the regulations adopted pursuant thereto. If the customer refuses to allow authorized representatives of the public works water division to inspect the system, the customer shall be required to install an approved backflow prevention device.
(Ord. XXX § 1, 2025; Ord. 376 § 1 (part), 1988: prior code § 4-10(6-7.05))

13.04.070 Backflow prevention devices—Required—Where and when.

An approved backflow prevention device shall also be installed on each service line to a customer's water system at or near the property line or immediately inside the building being served; but in all cases, before the first branch line leading off the service line wherever the following conditions exist:

A. In the case of premises having an auxiliary water supply which is not or may not be of safe bacteriological or chemical quality and which is not acceptable as an additional source by the director, the city water system shall be protected against backflow from the premises by installing a backflow prevention device in the service line appropriate to the degree of hazard.

B. In the case of premises on which any industrial fluids or any other objectionable substance is handled in such a fashion as to create an actual or potential hazard to the city water system, the city system shall be protected against backflow from the premises by installing a backflow prevention device in the service line appropriate to the degree of hazard. This shall include the handling of process waters and waters originating from the city system which have been subject to deterioration in quality.

C. In the case of premises having (1) internal cross-connections that cannot be permanently corrected and controlled, or (2) intricate plumbing and piping arrangements or where entry to all portions of the premises is not readily accessible for inspection purposes, making it impracticable or impossible to ascertain whether or not dangerous cross-connections exist, the city water system shall be protected against backflow from the premises by installing a backflow prevention device in the service line.

Created: 2025-04-02 08:09:26 [EST]
(Supp. No. 23, Update 1)

D. In the case of premises identified in Appendix D, or whenever any other hazard is identified by the director following a hazard assessment.
(Ord. XXX § 1, 2025; Ord. 376 § 1 (part), 1988: prior code § 4-10(6-7.06))

13.04.080 Backflow prevention devices—Required—Type.

The type of protective device required under Section 13.04.070(A), (B) and (C) shall depend upon the degree of hazard which exists as follows:

A. In the case of any premises where there is an auxiliary water supply as stated in Section 13.04.070(A), (B) and (C) and it is not subject to any of the following rules, the city water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention device.

B. In the case of any premises where there is water or substance that would be objectionable but not hazardous to health, if introduced into the city water system, the city water system shall be protected by an approved double check valve assembly.

C. In the case of any premises where there is any material dangerous to health which is handled in such a fashion as to create an actual or potential hazard to the city water system, the city water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention device. Examples of premises where these conditions will exist include sewage treatment plants, sewage pumping stations, chemical manufacturing plants, hospitals, mortuaries and plating plants.

D. In the case of any premises where there are uncontrolled cross-connections, either actual or potential, the city water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention device at the service connection.

E. In the case of any premises where, because of security requirements or other prohibitions or restrictions it is impossible or impractical to make a complete cross-connection survey or hazard assessment, the city water system shall be protected against backflow or back-siphonage from the premises by the installation of a backflow prevention device in the service line. In this case, maximum protection will be required; that is, an approved air-gap separation or an approved reduced pressure principle backflow prevention device shall be installed in each service to the premises. (Ord. XXX § 1, 2025; Ord. 376 § 1 (part), 1988: prior code § 4-10(6-7.07))

MANAGEMENT REPORT

CITY OF SHAFTER

CITY COUNCIL REPORT
MEETING DATE: September 2, 2025
DEPARTMENT: Michael James, Public Works Director
SUBJECT: AUTHORIZE GENERAL FUND APPROPRIATION FOR

REIMBURSEMENT OF SEWER MAIN CONSTRUCTION COSTS,
WAIVE THE CITY’S BIDDING REQUIREMENTS, AND

AUTHORIZE A REIMBURSEMENT AGREEMENT WITH SHAFTER

RECREATION & PARKS DISTRICT

RECOMMENDATION
Council find that the project is exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15282(k) of the CEQA Guidelines (installation of pipeline less than one mile in length); approve a General Fund appropriation of $100,000 for the reimbursement of off-site sewer main construction costs; waive the City’s bidding requirements and authorize the City Manager and Public Works Director to draft and execute the reimbursement agreement with the Shafter Recreation and Parks District, subject to approval by the City Attorney.

BACKGROUND
The Shafter Recreation and Parks District (“District”) is currently developing a new public park site near the intersection of Golds Avenue and Lerdo Highway. As part of the required infrastructure, the District is constructing new sewer improvements to serve the park. The City of Shafter (“City”) has identified an opportunity to extend this sewer infrastructure beyond the District’s immediate project area to serve City-owned parcels located less than one mile north of the park. These parcels are currently vacant but are zoned for Business Park development.

To capitalize on the construction already occurring and avoid the need for future mobilization, the City proposes to authorize the District contractors to extend the sewer pipeline to the City parcels, specifically to a public right-of-way referred to as "North Alley" in the District's park improvement plans.. Later, the City could reimburse the District for the incremental cost of constructing the extension of a sewer main. This offsite extension will allow future development on the City’s properties to connect to sewer service more efficiently and at a lower cost. In addition to reducing overall construction expenses, this coordinated effort avoids duplicative permitting, environmental review, and public disruption that would otherwise be required for a future standalone project.

This action will authorize the development and execution of a reimbursement agreement between the City and Recreation & Park District that will outline standard

terms of construction, reimbursement of the District by the City, and project inspections and coordination. The agreement will be subject to review and approval by the City Attorney. Upon approval by the City Manager and City Attorney, the agreement may be executed by the City Manager and the Public Works Director.

The bidding and procurement regulations of the City of Shafter would normally require the City to obtain three informal bids for a public works project not exceeding $100,000 in cost. However, staff recommends that the Council waive the solicitation of informal bids since the purposes of bidding would be unavailing and would not produce an advantage.” (Graydon v. Pasadena Redevelopment Agency104 Cal. App. 3d 634 (1980) ). This principle has been recognized by courts to allow a public entity to forgo the standard bidding process under specific situations as noted here where a different public entity has bid and authorized the project, the contractor forces are already mobilized (resulting in significant cost savings) and there would be no competitive advantage to be gained by separately bidding the work.

This collaborative approach allows the City to proactively install infrastructure to support future Business Park development, while minimizing costs, regulatory hurdles, and future disruption.

FISCAL IMPACT
The proposed reimbursement to the Shafter Recreation and Parks District in the amount of $94,785.92 is not currently budgeted and will require a General Fund appropriation of $100,000 to cover the reimbursement and any incidental administrative costs. While this represents a new expenditure, it is expected to result in substantial long-term savings. The City had previously estimated a cost of approximately $400,000 to construct a separate sewer main extension around the park site in the future. By coordinating with the District’s current construction project, the City can achieve the same infrastructure goals at less than 25% of the previously projected cost.

CEQA ANALYSIS
The proposed action is exempt from the requirements of the California Environmental Quality Act (CEQA) pursuant to Section 15282(k) of the CEQA Guidelines (installation of pipeline less than one mile. Upon approval, staff will be authorized to file a Notice of Exemption with the state clearinghouse.
