1 Cross Connection Control Policy Overview

1.1 Objective
The primary objective of the Cross-Connection Control Management Plan (CCCMP) is to bring the City into compliance with the Cross Connection Control Policy Handbook ( CCCPH) developed by the State Water Resources Control Board (State Water Board) for the protection of public health through the establishment of standards intended to ensure a public water system’s (PWS) drinking water distribution system will not be subject to the backflow of liquids, gases, or other substances , see CCCMP Appendix A . In addition, by providing basic educational information on backflow prevention, the City intends to build a foundation of awareness within the City regarding the importance of backflow protection and cross-connection control, leading to the implementation of a robust cross-connection control program.

Per Section 3.1.4 (b)(1) description the City will implement the requirements of the State CCCPH by implementing ordinances and procedures as detailed in this CCCMP.

1.2 Applicability
The State CCCPH and its standards apply to all California PWSs, as defined in California’s Health and Safety Code (CHSC, section 116275 (h)). Compliance with the State CCCPH is mandatory for all California PWSs. The City’s CCCMP has been developed in conformance to the State CCCPH and is applicable to all customers within the City’s service area.

1.3 Policy Development Background and Legal Authorities Through the adoption of the State CCCPH, the State Water Board exercised its authority, under California’s Safe Drinking Water Act (SDWA), to establish enforceable standards applicable to California’s PWSs. Failure to comply with the CCCMP which is in conformance with the State CCCPH may result in the issuance of compliance, enforcement, or other corrective actions against the City.

1.4 California Safe Drinking Water Act

On October 6, 2017, Assembly Bill 1671 (AB 1671) was approved and filed with the Secretary of State ( see CCCMP Appendix B ). AB 1671 amended California’s SDWA through the establishment of CHSC sections 116407 and 116555.5. AB 1671 also amended section 116810 of the CHSC, which is briefly discussed in CCCPH.

On October 2, 2019, Assembly Bill 1180 (AB 1180) was approved and filed with the Secretary 4-17
of State. AB 1180 amended Section 116407 of the CHSC and added section 13521.2 to the Water Code. AB 1180 requires that the CCCPH include provisions for the use of a swivel or changeover device (swivel-ell), see CCCMP Appendix B.

Pursuant to sections 116407 and 116555.5 of the CHSC, the State Water Board chose to adopt standards for backflow protection and cross-connection control through the adoption of this State CCCPH, which became effective July 1, 2024.

• The State Water Board is required to adopt regulations for the control of cross- connections that it determines to be necessary for ensuring PWSs “distribute a reliable and adequate supply of pure, wholesome, potable, and healthy water.” (CHSC section 116375, subd. (c).)
• Any person who owns a PWS is required to ensure that the distribution system will not be subject to backflow under normal operating conditions. (CHSC section 116555, subd. (a)(2).)

Prior to AB 1671 and the adoption of th e State CCCPH, California’s regulations pertaining to cross-connection control were set forth in regulations in CCR Title 17, which were adopted in 1987 with minor revisions in 2000. Although still protective to public health, the CCR Title 17 cross-connection regulations required updating as both the drinking water and cross-connection control industries had evolved. This State CCCPH updates those regulations, which as previously noted are no longer operative following the adoption of the State CCCPH.

The State Water Board may update its standards for backflow protection and cross- connection control through revisions of the State CCCPH. Prior to adopting substantive revisions to the State CCCPH, the State Water Board will consult with state and local agencies and persons identified as having expertise on the subject by the State Water Board, and the State Water Board will hold at least one public hearing to consider public comments.

2 Hazard Assessments and Required Protection

In accordance with the State CCCPH, Section 3.1.3 (a)(3) – Hazard Assessments, Section 3.1.4 (b)(2), and Section 3.2.1 – The City must survey its service area and conduct hazard assessments per Article 2 of the State CCCPH that identifies actual or potential cross-connection hazards, degree of hazard, and any backflow protection needed.

2.1 Hazard Assessments

a. To evaluate the potential for backflow into the City’s water distribution system the City must conduct an initial hazard assessment of the user premises within its service area.

The hazard assessment must consider:

1. The existence of cross-connections;

2. the type and use of materials handled and present, or likely to be, on the user premises;

3. the degree of piping system complexity and accessibility;

4. access to auxiliary water supplies, pumping systems, or pressure systems;

5. distribution system conditions that increase the likelihood of a backflow event (e.g., hydraulic gradient differences impacted by main breaks and high water- demand situations, multiple service connections that may result in flow-through conditions, etc.);

6. user premises accessibility;

7. any previous backflow incidents on the user premises; and

8. the requirements and information provided in the State CCCPH, and the City’s CCCMP.

b. Each hazard assessment must identify the degree of hazard to the City’s distribution system as either a high hazard cross -connection, a low hazard cross - connection, or having no hazard. Examples of some high hazard cross-connection activities may be found in CCCMP Appendix D.

c. The hazard assessment must determine whether an existing BPA, if any, provides adequate protection based on the degree of hazard.

d. Hazard assessments completed prior to the adoption of the State CCCPH may be considered as an initial hazard assessment provided that such hazard assessments and associated backflow protection provide protection consistent with the State CCCPH and the City describes their review of these assessments in the City’s CCCMP.

e. Subsequent to the initial hazard assessment described in subsection (a), the City must perform a hazard assessment under the following criteria:

1. if a user premises changes account holder, excluding single-family residences;

2. if a user premises is connected to the City’s water distribution system; 4-24

3. if evidence exists of changes in the activities or materials on a user’s premises;

4. if backflow from a user’s premises occurs;

5. periodically, as identified in the City’s CCCMP required pursuant to State CCCPH section 3.1.4.;

6. if the State Water Board requests a hazard assessment of a user’s premises; or

7. if the City concludes an existing hazard assessment may no longer accurately represent the degree of hazard.

f. A cross- connection control specialist must review or conduct each initial and follow-up hazard assessment pursuant to this section and make a written finding that, in the specialist’s judgment based on cross -connection control principles, the City’s hazard assessment properly identified all hazards at the time of the assessment, the appropriate degree of hazards, and the corresponding backflow protection.

2.2 Hazard Assessment Process
In order to assess each connection in the City’s water distribution system for potential cross connection the City will undertake assessments in the following phases. As part of the hazard assessment process the City has created a tracking system for the assessments made under the CCCMP. See CCCMP Appendix D.

Data will be gathered and logged into the assessment database in three phases. The assessment database will be maintained per the procedures outlined in Section 9 of the CCCMP.

• Phase 1 - All connections with existing backflow prevention assemblies at the meter connection
• Phase 2 - All commercial/industrial connections without backflow prevention assemblies at the meter connection
• Phase 3 - All residential connections with AMI (Automated Meter Infrastructure) meters

2.2.1 Phase 1 - Connections with Backﬂow Protection
The City currently has, as of April 6, 2025, 2,110 connections with backflow protection installed at the meter. For connections with backflow protection the City will enter each address into the assessment tracking system indicating what type of BPA has been installed. The City’s Cross Connection Control Specialist will review the data when entered into the assessment database to verify that an appropriate BPA has been installed on the meter connection. The Cross Connection Control Specialist’s review date will be noted in the assessment database.

It is assumed that a Cross Connection Control Specialist can process (5) existing connections wi
th backflow protection installed at the meter per available hour, and the total number of annual Cross Connection Control Specialist available hours is 93 hrs./yr (5% of total annual 1,867 hrs), for a total of 465 existing connections per year per Cross Connection Control Specialist assigned by the City to cross connection control.

4-25
Based on the availability of the Cross Connection Control Project Specialist the City has determined that this phase of the assessments can be completed within 2 .7 years fr om the adoption of the City’s CCCMP.

2.2.2 Phase 2 - Commercial/Industrial/Institutional Connections without Backﬂow Protection
The City currently has as of 05/27/2025, 834 commercial/industrial/institutional sites without backflow protection installed at the meter. For those non -residential connections without an approved BPA the City will provide a Site Assessment Form to provide information regarding onsite conditions which would necessitate the installation of an approved BPA at the meter connection.

The site assessment form to be completed by City staff may be found in CCCMP Appendix F.

It is assumed that a Cross Connection Control Specialist can completed one site visit for existing conn
ections without backflow protection installed at the meter per available hour, and the total number of annual Cross Connection Control Specialist available hours is 93 hrs./yr (5% of total annual 1,867 hrs), for a total of 465 existing commercial/industrial connections without per year per Cross Connection Control Specialist assigned by the City to cross connection control.

Bas
ed on the availability of the Cross Connection Control Project Specialists the City has determined that this phase of the assessments can be completed within 1 year and 10 months from the completion of Phase 1.

• If the Cross Connection Control Specialist determines that based on the site assessment form that an approved BPA is not required, they will note that in the assessment database and the reason for not requiring an approved BPA.

• If the Cross Connection Control Specialist determines that based on the site assessment form that an approved BPA is required, they will note that in the assessment database and notify the commercial/industrial customer that an approved BPA must be installed at the meter connection and note that determination in the assessment database.

2.2.3 Phase 3 – Residential Connections with AMI Meters There are, as of April 23, 2025, a total of 23,092 residential AMI meters installed in the City’s water distribution system. All residential connections are equipped with AMI meters and flow is monitored on a continuous basis and can inform the City of a backflow condition when it occurs.

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 4-26
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

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 office- based 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 office- based 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 Specialist can process (25) existing residential conn
ections with AMI meters installed per available hour, and the total number of annual Cross Connection Control Specialist available hours is 93 hrs./yr (5% of total annual 1,867 hrs ), for a total of 465 existing residential connections equipped with AMI meters per year per Cross Connection Control Specialist assigned by the City to cross connection control.

Bas
ed on the availability of the Cross Connection Control Project Specialist the City has determined that this phase of the assessments can be completed within 9 years and 11 months from the completion of Phase 2.

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

4-27
3 Operating Rules or Ordinances

In accordance with the State CCCPH, Section 3.1.3 (a)(1), and Section 3.1.4(b)(1) and Section

3.1.4 (b)(3),the City must have operating rules, ordinances, by-laws, or a resolution to implement the cross- connection program. The City must have legal authority to implement corrective actions in the event a water user fails to comply in a timely manner with the City’s provisions regarding the installation, inspection, field testing, or maintenance of BPAs required pursuant to this Section. Such corrective actions must include the City’s ability to perform at least one of the following:

• D eny or discontinue water service to a water user,
• I nstall, inspect, field test, and/or maintain a BPA at a water user’s premises, or • O therwise address in a timely manner a failure to comply with the City’s cross-connection control program.

The City’s backflow and cross-connection prevention requirements are contained in the City’s Municipal Code, Chapter 14.10 – Cross-Connection Control Program Sections 14.10.005 through 14.10.045. A copy is attached as CCCMP Appendix C.

City staff are currently in the process of updating the City’s Municipal Code, Chapter 14.10 – Cross-Connection Control Program Sections 14.10.005 through 14.10.045, which will then be adopted by the City of Newport Beach City Council.

The first informational presentation of the updated Code will take place at the July 22, 2025 City Council Meeting. Then the updated Code and Ordinance will go to the next City Council meetings for 2
nd reading currently scheduled for August 26th. The City’s Municipal Code effective date will be September 26th.

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 269 backflow assemblies installed at the water connections, and 25 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 4.2.1 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 D 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 CCCMP Appendix G;
4-29
(4) at least every 12 months, inspections are performed and documented to confirm ongoing compliance with the design and construction- related requirements in CCCMP Appendix G;

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 as backflow prevention assembly tester or certified as a cross- connection control 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 at the discretion of the Cross Connection Control Specialist.

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
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.

Mailed to all premises with BPA. User has 30 days to provide BPA test results by return mail or email
4-47

• Second notice – if the BPA test results are not received by the City within 30 days after the first notice was sent to the user, a second notice will be sent to the user – by mail, giving the customer 15 days to provide the required BPA test results.

• Third notice– if the BPA test results are not received by the City within 15 days after the second notice was sent to the user, City staff will visit the customer to inform them of the BPA testing requirements and inform them that failure to provide the BPA test results will lead to terminating water service within 24 hrs.

• Termination of water service – if the user fails to provide the required BPA test results with the 24-hour final notice water service will be terminated or under the City of Newport Beach’s discretion.

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 missing (or stolen), installed incorrectly, illegally modified, or tampered with, and provide them 30 days to replace, repair, or re-install the BPA.

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, 4-52
including those which are not apparent until a significant change in water level occurs or where 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 cross - connection 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 i dentify 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 cross - connection 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” 4-53
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 cross- connection 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.

Ch. 533 — 2 —

(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. S ection 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 4-57
— 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.

Assembly Bill No. 1180
CHAPTER 455

An act to amend Section 116407 of the Health and Safety Code, and to add Section 13521.2 to the Water Code, relating to water.

[Approved by Governor October 2, 2019. Filed with Secretary of State October 2, 2019.]
legislative counsel’s digest
AB 1180, Friedman. Water: recycled water.
(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. Existing law requires, on or before January 1, 2020, the state board to adopt standards for backflow protection and cross-connection control through the adoption of a policy handbook, as specified.

This bill would require that handbook to include provisions for the use of a swivel or changeover device to supply potable water to a dual-plumbed system during an interruption in recycled water service.
(2) Existing law requires the state board to establish uniform statewide recycling criteria for each varying type of use of recycled water where the use involves the protection of public health.

This bill would require the state board, on or before January 1, 2023, as specified, to update the uniform statewide criteria for nonpotable recycled water uses.

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

SECTION 1. The Legislature finds and declares all of the following:
(a) On December 11, 2018, the State Water Resources Control Board unanimously adopted an amendment to the policy for water quality control for recycled water, which included a goal to increase the use of recycled water in the state from 714,000 acre -feet per year in 2015 to 1,500,000 acre -feet per year by 2020 and 2,500,000 acre-feet per year by 2030.
(b) Section 13521 of the Water Code requires the state board to establish uniform statewide recycling criteria for each varying type of use of recycled water where the use involves the protection of public health.
