Data, AF Form 845, Cross-Connection and Device Information, and AF Form 848, Survey of Cross-Con-nection Control and Backflow Prevention Devices; and rescinds AF Form 844, Backflow Prevention Inspection Data.

Section A—Uniform Plumbing Code Criteria

1. Publication Objective. People working and living on our bases need safe and secure water and plumbing systems. To fulfill this need, the base civil engineer's (BCE) team must have an effective back-flow prevention program. This instruction, the UPC, and the UPC Illustrated Training Manual provide guidance to help achieve these objectives.

2. Using this Instruction, the UPC, and the UPC Illustrated Training Manual. These publications contain plumbing information related to backflow prevention and cross-connection control, backflow device inspection frequency, unique maintenance tasks, and certification procedures. Consult the UPC and the UPC Illustrated Training Manual for specific planning and working knowledge of plumbing fix-tures, devices, systems, and codes.

3. UPC Compliance Procedures.

3.1. UPC Compliance Date. Through release of this AFI, the Air Force adopts the backflow require-ments of the UPC (2006 edition) and the UPC Illustrated Training Manual, published by the Interna-tional Association of Plumbing and Mechanical Officials (IAPMO), 5001 E. Philadelphia Street, Ontario CA 91761 (909-472-4100/4208). IAPMO updates and republishes these publications every 3 years. When an updated version of the UPC or UPC Illustrated Training Manual is published by IAPMO, the backflow requirements in these updated publications become a part of this instruction.

3.2. UPC Compliance Guidelines.

3.2.1. Bases under United States (US) jurisdiction must use the UPC (Section 603, Cross-Connec-tion Control) and UPC Illustrated Training Manual to inspect, test, install, repair, and replace backflow prevention devices. (Fire protection systems are exempted from this requirement. See Section 6.6. for fire protection systems requirements.) In the 1996 revisions to the Safe Drinking Water Act (SDWA), Public Law (PL) 93-523, December 16, 1974, Congress enacted a waiver of sovereign immunity that applies to Federal, state, intrastate, and local requirements with respect to "public water systems." This waiver can impose state and local backflow protection requirements on bases under US Environmental Protection Agency (EPA) jurisdiction (i.e., US states and terri-tories). See Attachment 2 for information on when state and local backflow protection require-ments may apply.

3.2.2. For bases located outside the US and its territories, paragraph 3.2.1. applies, except when in conflict with the Final Governing Standards (FGS), Overseas Environmental Baseline Guidance Document (OEBGD), or host country regulations that are enforceable under treaties or sta-tus-of-forces agreements (SOFA). In these situations, comply with the most stringent requirement.

Request guidance from the MAJCOM backflow program manager (BPM) for unresolved con-flicts.

3.2.3. In accordance with UFC 3-420-01, all bases must comply with the International Code Council's (ICC) International Plumbing Code® (IPC) for plumbing system design. See Section

3.5. for how to deal with publication conflicts.

AFI32-1066 17 OCTOBER 2007 3

3.3. UPC Administrative Authority. Chapter 1 of the UPC does not apply to Air Force personnel.

The BCE is the administrative authority for the installation, operation, maintenance, and replacement of backflow prevention devices.

3.4. Purchasing the UPC and UPC Illustrated Training Manual. Because HQ AFCESA/CEO is a Class A member of IAPMO, Air Force organizations and members can buy IAPMO publications at membership prices. Order copies for official use from IAPMO through the base library or contracting office. The toll-free publication ordering number is 800-854-2766. To receive Air Force membership prices, mark the order "For Use by US Air Force."

3.4.1. Air Force personnel can purchase personal copies of these publications directly from the publisher. To receive Air Force membership prices, mark the order according to paragraph 3.4.

The publisher also has publications pertaining to other civil engineering career fields. The UPC contains a list of these publications.

3.4.2. Each MAJCOM, BCE organization, and education or training school should review the IAPMO Product Listing Directory at http://pld.iapmo.org/ for a list of IAPMO-approved prod-ucts grouped by manufacturer. These plumbing products have passed the IAPMO laboratory test for their intended purpose. The list contains many manufacturers offering a wide variety of plumb-ing products, and it is a useful reference for locating acceptable plumbing material, fixtures, and backflow devices.

3.5. Publication Conflicts.

3.5.1. This AFI contains several deviations from the UPC that take precedence over the require-ments of the UPC and IPC. Certain Department of Defense (DoD) publications (including military handbooks and UFC) require compliance with the IPC in certain circumstances. When the back-flow requirements of this AFI, the UPC, and the IPC conflict, comply first with this AFI, second with the UPC, and third with the IPC. Notify the MAJCOM BPM and the HQ AFCESA Engineer-ing Support Directorate Civil Engineering Division (HQ AFCESA/CEOA) of any unresolved con-flicts.

3.5.2. In some situations, state and local laws for backflow prevention take precedence over this AFI and other Air Force and DoD guidance. See Attachment 2 for information on when state and local backflow protection requirements may apply.

Section C—Backflow Prevention

5. Cross-Connection Control Terms. Refer to the UPC and UPC Illustrated Training Manual, Chapter 2, for common cross-connection and backflow term definitions. Abbreviations and acronyms in this AFI are listed in Attachment 1; specific terms in this AFI are defined in paragraphs 5.1. through 5.9.

5.1. Approved Device. An approved device is a device that has been tested and approved by the IAPMO laboratory. IAPMO-approved devices carry an attached or imprinted IAPMO seal of approval. Alternately, acceptable devices are those approved by the FCCCHR or the American Soci-ety of Sanitary Engineering (ASSE). The BCE, with BEE and command BPM coordination, may authorize the use of new devices not yet approved by IAPMO, FCCCHR, or ASSE; however, the BCE must be confident that the use of these devices and their installation location and orientation will pro-vide adequate protection.

5.2. Backflow Preventer (Device or Assembly). A backflow preventer is a device or assembly to prevent backflow into the potable water system. The terms "backflow preventer," "backflow device," and "backflow assembly" are used interchangeably in the industry and in this document.

5.3. Backflow Prevention/Cross-Connection Survey (Survey). The survey and related tasks are described in paragraphs 7. through 7.4. The survey of backflow prevention assemblies and cross-con-nections will be conducted at least every five years by qualified personnel in accordance with para-graph 9.4.

6 AFI32-1066 17 OCTOBER 2007

5.4. Backflow Prevention Test and Inspection (Test). This term refers to an annual inspection and testing of backflow prevention assemblies by certified technicians. Paragraphs 8. and 9. of this AFI detail testing and technician certification requirements, respectively.

5.5. Readily Accessible. A device that is readily accessible is one that is located to within 1 to 5 feet above the floor or grade to provide access with adequate clearance for testing, maintenance, and repair. In addition, devices should be installed at least 1 foot from the back wall, have at least 1 foot above for maintenance, and have a minimum of 2 feet clearance on the side of the valve on which the test cocks are located. If a new or existing device is located higher than 5 feet above the grade or floor, a permanent platform or structure shall be provided for safely inspecting, testing, and maintaining the device.

5.6. High Hazard. A high hazard is also defined as "contamination" and is an impairment of the quality of the potable water that creates an actual hazard to public health through poisoning or through the spread of disease by sewage, industrial fluids, chemicals, or wastewaters.

5.7. Low Hazard. A low hazard is also defined as "pollution" and is an impairment of the quality of the potable water to a degree that does not create a significant hazard to the public health, but that does adversely and unreasonably affect the aesthetic quality of potable water for potable use.

5.8. Cross-Connection. Any connection between a potable water supply system and any system, fix-ture, or other device through which it may be possible for non-potable, polluted or contaminated water, or other substances to enter the potable water system under any condition.

5.9. Critical Water System. A critical water system is a facility or piece of equipment where a tem-porary loss of water service would directly and significantly impact military operations and where no alternative "work-arounds" or mitigation measures are feasible.

6. Use and Installation of Backflow Prevention Equipment.

6.1. Design of Equipment. BCE personnel must first consider designing a solution to eliminate the potential for a cross-connection. If this is not feasible, install an approved backflow prevention device to prevent contamination of potable water supplies susceptible to backpressure or back-siphonage from any contamination source. If the water use served by a backflow preventer is deemed critical by the BCE, install approved backflow preventers in parallel to allow maintenance or repair of the back-flow preventer without system shutdown.

6.2. Device Accessibility. New and existing backflow devices will be planned for and installed to be readily accessible as defined in paragraph 5.5. The BPM may exempt a device from being located in a readily accessible position if no safe, reasonable, or feasible location can be provided. Exemption should be documented on AF Form 845.

6.3. Device Location Safety. Locate devices outside of areas containing toxic, poisonous, or corro-sive fumes unless the installation is approved by the command BPM. In addition, reduced-pressure and other venting devices shall not be installed immediately above electrical panels and chemical stor-age areas unless approved by the BPM. Relief ports, collector assemblies, and drainage piping con-nected to venting devices shall not be located in or drained to locations that potentially create flooding hazards. Drainage piping shall be twice the pipe diameter of the piping to the backflow device.

6.4. Device Protection. Enclosures should be installed to secure exterior backflow preventers serv-ing critical or high-risk facilities such as those identified in the installation's Water Vulnerability

AFI32-1066 17 OCTOBER 2007 7

Assessment and other force protection documents. Enclosures should be designed to prevent tamper-ing and prevent adversaries from using the backflow preventer to introduce contaminants to the build-ing's drinking water system. Backflow preventers serving only non-potable uses (i.e., fire protection systems) are excluded.

6.5. Hose Bibb Devices. Specify atmospheric vacuum breaker-type devices that meet ASSE Stan-dard 1011-2004, Performance Requirements for Hose Connection Vacuum Breakers, at a minimum. In commercial, industrial, and recreational areas, install nonremovable hose bibb-type backflow devices on potable water outlets when there is the potential for contaminants or pollutants to enter through hoses. Protection must be provided where attached hoses can be submerged or are normally unat-tended when used. In freezing climates, self-draining, frost-proof hose bibbs with integral backflow preventers or vacuum breakers are highly recommended. Hose bibbs in housing areas are not required to have backflow devices unless documented hazards exist.

6.6. Fire Suppression Systems. Backflow protection on Air Force fire suppression systems shall be in accordance with Chapter 6 of AWWA Manual M14 in lieu of the UPC. UFC 3-600-01, Fire Protec-tion Engineering for Facilities, requires that fire suppression systems be in accordance with National Fire Protection Association (NFPA) 13, Standard for the Installation of Sprinkler Systems. NFPA 13 requires backflow preventers to be approved and listed for fire protection use by acceptable testing agencies such as Underwriters Laboratories Inc.® or Factory Mutual Research Corporation. Because pressure loss through a backflow preventer can degrade the effectiveness of a fire suppression system, design and submittal acceptance must ensure that the rated working flow rate of the backflow preven-tion device selected or installed meets the flow requirements of the system. If a backflow device must be mounted in a vertical position, ensure that the device is rated and approved for vertical installation.

Fire protection systems that use non-potable water are exempt from backflow requirements.

6.6.1. New Fire Suppression Systems. All new fire suppression systems using potable water shall have backflow prevention installed. Install a double check valve backflow preventer on new dry/wet fire suppression systems that use only water as a fire suppressant (with or without fire department (Siamese) connections). Use a reduced pressure-type backflow device only where antifreeze, foam, or other hazardous chemicals are added, or where local or state requirements require such devices and the waiver of sovereign immunity applies. (See Attachment 2 for more information on waivers of sovereign immunity.)

6.6.2. Existing Fire Suppression Systems. Existing fire suppression systems using only water as a fire suppressant are exempted from the backflow requirements for new systems if they met the existing backflow requirements at the time they were installed. (In most cases, prior to 1994 there were no Air Force or SDWA backflow prevention requirements for Air Force fire suppression sys-tems.) Systems that use antifreeze, foam, or other hazardous chemicals shall be retrofitted with a reduced pressure backflow device. When replacing or upgrading backflow protection on existing systems, or making significant modifications to the fire suppression system, install a double check valve backflow preventer on dry/wet fire suppression systems that use only water as a fire sup-pressant. Install a reduced pressure-type backflow device only where antifreeze, foam, or other hazardous chemicals are added, or where the local, state, or water provider codes specifically require existing water-only fire protection systems to be retrofitted with such a device. When there is a valid requirement to upgrade, install, or change a backflow device on a fire protection system, increased pressure losses and resulting lower flow rates must be considered. A registered Profes-sional Engineer (PE) (preferably a fire protection engineer) must approve the design and all sub-

8 AFI32-1066 17 OCTOBER 2007

mittals for any additions or changes to the backflow protection devices installed on fire protection systems.

6.6.3. Hydraulic Losses. Pressure losses through a backflow prevention device will degrade the effectiveness of a fire protection system. Design and submittal acceptance by a registered PE must be completed to ensure that the rated working flow rate of the selected valve will meet the flow requirements of the system. In some cases, significant modifications to the fire protection system are required to offset the pressure loss caused by the backflow device.

7. Water System Backflow Prevention/Cross-Connection Survey.

7.1. Conducting Surveys. Every five years, under the supervision of the base BPM, BCE personnel, with the assistance of the BEE or qualified BE personnel and/or qualified contractors, shall survey all facilities and water-using equipment and systems. Alternately, an annual survey of 20 percent of the facilities and devices may be performed. An annual survey program must ensure that no facility, sys-tem, or device goes longer than five years without being surveyed. A survey shall be conducted of new buildings upon facility completion and prior to acceptance. Surveys shall include, as a minimum, a detailed inventory of assemblies, identification of cross-connections, a description of water usage, classification of hazard, and selection of proper protection, and shall be performed by a surveyor meeting the qualification requirements in paragraph 9.4. (In accordance with the HQ USAF/ILEV policy letter dated 9 August 2002, backflow surveys are not eligible for environmental funding.)

7.2. Documenting Surveys. The result of the team's survey of existing devices shall be documented on AF Form 848, a computerized maintenance management system (CMMS), or state submittal forms. Note: State forms or CMMS records must record information that is equivalent to the informa-tion on the Air Force form. With adequate information, these documents are a suitable substitute to using the prescribed Air Force form. The BPM uses this information to maintain other records for installed devices and to set testing schedules. The survey team documents the requirements for new or additional backflow prevention devices. The BPM will centrally maintain inspection records and the status of installation and upgrade actions. Note: Immediate actions shall be taken to eliminate high (i.e., contamination) cross-connection hazards.

7.3. Survey Exclusions. Housing areas are excluded, except houses with underground lawn sprinkler systems fed with potable water. (The BCE may include housing areas if hazards are suspected.) Stan-dard interior plumbing fixtures are also excluded, except laboratory and mop sinks with threads for hoses. Areas not under Air Force control are also excluded (i.e., privatized housing areas).

7.4. Existing Devices. During the survey of cross-connections, identify all testable existing backflow protective devices by a control number. List unapproved or non-testable devices for replacement.

8. Testing and Inspecting Backflow Preventers.

8.1. Inspection Schedule. The BPM ensures that a schedule is developed and used by certified tech-nicians to inspect and test backflow assemblies.

8.2. Annual Inspection Tasks. A certified backflow technician shall inspect identified cross-connec-tion locations to ensure that:

8.2.1. Proper air gaps are maintained.

8.2.2. Backflow prevention devices are in good condition and readily accessible.

AFI32-1066 17 OCTOBER 2007 9

8.2.3. Newly installed devices were installed correctly and are free of debris that could interfere with their testing or functioning.

8.2.4. Devices have been properly insulated and protected against freezing weather conditions and that test ports are accessible.

8.3. Testing Devices. Test all devices in accordance with FCCCHR's Manual of Cross-Connection Control, Section 9, or the manufacturer's instructions for the particular device, or using procedures recognized by the tester's certifying agency. At a minimum, testable devices shall be tested after installation, cleaning, repair or relocation, and at least annually.

8.4. Documentation of Inspections and Testing.

8.4.1. Technicians record test data on AF Form 843 and AF Form 845, state mandated forms, the Automated Civil Engineer System Program Management module (ACES-PM), or another CMMS system approved by the base BPM.

8.4.2. The base BPM shall maintain backflow prevention and cross-connection control program documents at a central location. Maintain and update inventory records of all device locations (AF Form 848) and copies of individual records (AF Form 845) for each assembly. Upon implementa-tion of ACES-PM, backflow assembly information should be entered and subsequently managed via this module. Although ACES-PM will be available to installations, the base BPM may approve use of a different CMMS for data management. It is the responsibility of the base BPM to ensure that technicians' records are complete and current.

Section D—Backflow Certification Program

9. General Certification Information. To protect potable water, only certified military or civilian per-sonnel or contractors are authorized to test and maintain backflow prevention devices. Additionally, only qualified personnel are authorized to conduct cross-connection surveys. Certification is essential in meet-ing the standards of the SDWA, as amended, Title 42 United States Code (USC) Section 300f et seq. The Air Force program allows the flexibility of moving Air Force technicians from state to state without hav-ing to retrain and recertify them; however, where Federal agencies and personnel are not exempt from state laws mandating backflow certification, state certification requirements apply due to the waiver of sovereign immunity. (See Attachment 2 for more information on waivers of sovereign immunity.)

9.1. Technician Certification Procedures. Backflow technicians shall have either a current back-flow/cross-connection certification from the state, or they shall have a certification issued by the MAJCOM. MAJCOMs certify and recertify backflow prevention technicians assigned to their com-mand using database systems such as the ACES-PM module, a CMMS, or AF Form 483. All MAJ- COM certifications expire after three years. Transfer of personnel between MAJCOMs does not require recertification until the certificate expires. Similar certificates obtained by technicians from states or other governmental agencies or organizations are valid until they expire.

9.2. MAJCOM Technician Certification Requirements.

9.2.1. Initial Technician Certification. Backflow technician certifications shall be issued by the MAJCOM BPM based on the recommendation of the BCE. Individuals recommended by the BCE for MAJCOM certification should be:

10 AFI32-1066 17 OCTOBER 2007

9.2.1.1. A technician with at least a 5-level or equivalent experience. (After evaluating the cir-cumstances and based on a unique situation, specific location, or other factors, the BCE may decide to certify a lower skill level.)

9.2.1.2. A technician who has received on-the-job training and is experienced in inspecting and testing the types of devices installed at the installation.

9.2.1.3. A technician who has satisfactorily completed an approved training program such as:

9.2.1.3.1. Sheppard Technical Training Center's "Backflow Prevention Devices" course.

9.2.1.3.2. A backflow prevention course recognized by the host state. The technician must have passed the state's backflow device tester's examination.

9.2.1.3.3. A backflow prevention course sponsored by a nationally or internationally rec-ognized professional organization with written and performance examinations.

9.2.2. Technician Recertification. Backflow technicians shall obtain a MAJCOM recertification using data furnished by the BCE. For MAJCOM certification, the BCE shall request recertifica-tion and provide this information at least 60 days prior to the three-year anniversary date listed on AF Form 483:

9.2.2.1. Date the technician completed an approved retraining course unless the technician has inspected and tested a number (usually 50) of representative backflow device types since he or she was last certified.

9.2.2.2. Date and description of supplemental backflow prevention courses and training com-pleted.

9.2.2.3. Device types and frequency of tests, inspections, and maintenance tasks.

9.2.2.4. A statement attesting to the technician's proficiency maintaining said devices.

9.3. Personnel Gains and Losses. The BCE shall provide the MAJCOM a list of assigned certified technicians and update the list annually. The MAJCOM shall track the number of certified technicians for each of its bases.

9.4. Surveyor Qualification Requirements.

9.4.1. Cross-connection/backflow surveyors shall either meet Air Force surveyor requirements or shall be certified by the state as a backflow/cross-connection surveyor.

9.4.2. Air Force surveyors must have satisfactorily completed a training program such as:

9.4.2.1. A survey course addressing Federal and state regulations, cross-connection identifica-tion, and types and uses of backflow prevention devices recognized by the host state.

9.4.2.2. A survey course addressing Federal and state regulations, cross-connection identifica-tion, and types and uses of backflow prevention devices sponsored by a nationally or interna-tionally recognized professional organization with written and performance examinations.

INFORMATION ON WHEN STATE AND LOCAL BACKFLOW REQUIREMENTS MAY

APPLY TO AIR FORCE LOCATIONS

(Applicable to 50 US states and territories only)

A2.1. Waiver of Sovereign Immunity.

A2.1.1. In the SDWA § 1447 (Title 42 United States Code (USC) Section 300j-6), Congress enacted a partial waiver of sovereign immunity that applies to Federal, state, interstate, and local requirements with respect to "public water systems." This waiver can impact backflow protection requirements on bases under US EPA jurisdiction (i.e., US states and territories).

A2.1.2. Some states have enacted backflow requirements that are stricter than the requirements in this AFI. (There is no provision in the SDWA that prohibits states from being more stringent than Federal standards when using state SDWA authority. The provision that gives states authority to take over Federal programs says only that the program has to be at least as stringent as Federal requirements.)

Stricter backflow protection requirements fall under several areas. The main areas are:

A2.1.2.1. Frequency or level of maintenance of backflow preventers.

A2.1.2.2. Certification requirements for backflow technicians.

A2.1.2.3. Level of backflow prevention required (mainly affects fire protection systems).

A2.1.3. States have typically codified these stricter requirements in two ways. One is under state drinking water regulations; the other is under building or plumbing code regulations. Because the waiver of sovereign immunity extends only to "public water systems" as defined in SDWA § 1401(4), 42 USC § 300f(4), typically only requirements that were enacted under drinking water laws would apply to Air Force locations, whereas those requirements contained in plumbing or building codes generally would not apply. This is because application of those codes would generally not hinge on SDWA "public water system" status. In other words, if the state requirement specifically applies to "public water systems," it should be within the scope of the waiver of sovereign immunity, but the requirement would generally not apply if application of the requirement does not depend on "public water system" status.

A2.2. Hierarchy of Requirements.

A2.2.1. When state or local requirements are not binding on the Air Force, comply with the backflow program requirements in this AFI.

A2.2.2. When state or local requirements are binding on the Air Force, comply with the strictest requirements of the local requirements and this AFI. This may require using state mandated forms in place of Air Force forms, meeting state certification requirements for backflow technicians, and upgrading backflow protection requirements to meet state mandates.

A2.3. Determination of Requirements.

A2.3.1. The scope of a sovereign immunity waiver is necessarily fact-specific and very complex. The purpose of this appendix is to provide a general overview of how state and local backflow require-ments might apply.

A2.3.2. For a determination as to whether specific state or local requirements apply, Civil Engineer (CE) and BE personnel should refer questions to their base Legal Office or Judge Advocate.
