Item 8C~• ~* AGENDA ITEM #8C JUNE 14, 2004 CITY OF ATLANTIC BEACH CITY COMMISSION MEETING STAFF REPORT AGENDA ITEM: Update of Cross-Connection Control Program SUBMITTED BY: Donna Kaluzniak, Utility Direc DATE: June 4, 2004 BACKGROUND: The Department of Environmental Protection (DEP) defines across- connection as "any physical arrangement whereby a public water supply is connected, directly or indirectly, with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which may contain contaminated water... or liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water. supply as the result of backflow." The City Commission adopted the City's existing Cross-Connection Control Policy Manual in ~ March, 2000. City Code requires that the most recent copy of the Cross-Connection Control Policy be followed to implement appropriate backflow prevention methods and prevent ~„ contamination of the City's water supply. Recent changes to DEP's rule 62-555 have made cross-connection requirements more stringent, and necessitated the update of the City's policy. ~. One of the new requirements is complete implementation ofcross-connection programs, in other words, no "grandfathering" of existing potential cross connections are to be allowed. Probably the two areas with the most impact to Atlantic Beach customers include property owners with ,~ existing private wells and existing irrigation systems. Rule 62-555 requires the cross-connection program to use the recommended practices in the American Water Works Association Manual M14, Recommended Practice for Backflow Prevention and Cross-Connection Control. This manual, and the City's policy, require backflow preventers to be installed on services with irrigation systems, and on any premises having an "~' auxiliary water system such as a private well or pond, even if there is no current connection to the City water system. This is due to the potential for property owners to unknowingly have connections or for future cross-connections to occur. Due to the small cross-connection control staff (one person assigned part-time), efforts on the program to date have focused primarily on commercial facilities. However, staff has now reached the point where we can work on implementation of the program for residential areas as well, as we are required to do by law. This will include notification to property owners with ~,,, irrigation systems or auxiliary water systems to install proper backflow prevention. To determine how Atlantic Beach's program compares with other nearby programs, staff ~„ contacted the cross-connection personnel for the City of Jacksonville Beach and JEA. JEA's AGENDA ITEM #8C JUNE 14, 2004 policy manual is nearly identical to the Atlantic Beach program. Both JEA and Jacksonville '~ Beach require property owners with existing irrigation systems to retrofit with backflow prevention when these systems are discovered. Due to a staffing shortage, as well as the inability to determine the location of properties with auxiliary water supplies, JEA has not required cross- connection improvements of those owners, and neither has Jacksonville Beach. The attached draft of the revised City of Atlantic Beach Cross-Connection Control Policy Manual reflects the updated DEP rule requirements, as well as language corrections. BUDGET: No impact to the City budget. RECOMMENDATION: Adopt the revised City of Atlantic Beach Cross-Connection Control Policy Manual. ATTACHMENTS: 1. Draft Revised City of Atlantic Beach Cross-Connection Control Policy Manual. 2. E-mail from DEP explaining requirement for backflow prevention on properties with auxiliary water supplies. ~ REVIEWED BY CITY MANAGER: 2 ~. ~* AGENDA ITEM #8C JUNE 14, 2004 CITY OF ATLANTIC BEACH CROSS-CONNECTION CONTROL POLICY MANUAL 2004 Revised uneA~a~sk~ ~89A AGENDA ITEM #8C JUNE 14, 2004 TABLE OF CONTENTS TITLE PAGE INTRODUCTION ............................................................................................................................ 1 PART 1 -Overview ........................................................................................................................ 2 1.01 PURPOSE ..................................................................................................................2 1.02 CAUSES OF BACKFLOW ......................................................................................... 2 PART 2 -Responsibility ................................................................................................................ 3 2.01 CROSS-CONNECTION CONTROL PROGRAM ...................................................... 3 2.02 CUSTOMERS ............................................................................................................ 3 2.03 BACKFLOW PREVENTION DEVICE INSTALLERS ................................................ 3 ~• PART 3 -Inspections .................................................................................................................... 4 3.01 FREQUENCY .............................................................................................................4 ~,,, 3.02 PROPOSED CONSTRUCTIONS .............................................................................. 4 3.03 NEW AND EXISTING FACILITIES ............................................................................ 4 PART 4 - Debnitions ...................................................................................................................... 4 PART 5 -Cross-Connection Hazards and Required Protections ............................................ 7 5.01 FACILITIES ................................................................................................................ 7 5.02 FIRE SYSTEMS ....................................................................................................... 10 ~„ 5.03 OTHER CROSS-CONNECTION HAZARDS .......................................................... 10 5.04 BACKFLOW PREVENTION DEVICES (Illustrated) ................................................ 12 5.05 TYPICAL INSTALLATIONS (Illustrated) .................................................................. 15 PART 6 -Testing of Backf/ow Preventers ................................................................................ 21 ~"" PART 7 -Penalties for Non Compliance ................................................................................... 21 7.01 TERMINATION OF SERVICE ................................................................................. 21 7.02 MONETARY PENALTIES ........................................................................................ 21 PART 8 -Pertinent Sections of Local Codes ........................................................................... 22 Section 2-146.

Thus, in the exercise of this responsibility, the water purveyor must take reasonable precaution to protect the community distribution system from the hazards originating on the premises of its customers that may degrade the water in the community distribution system. It is realized that cross-connection control and plumbing inspections on premises of its customers are regulatory in nature and should be handled through the rules, regulations, and recommendations of the health authority or the plumbing-code enforcing agencies having jurisdiction. The water purveyor, however, should be aware of any situation requiring inspection and/or re-inspections necessary to detect hazardous conditions resulting from cross-connections. If, in the opinion of the utility, effective measures consistent with the degree of hazard have not been taken by the regulatory agency, the water purveyor should take such measures as he may-deem necessary to ensure that the community distribution system is protected from contamination. Such action would include the installation of a backflow prevention device, consistent with the degree of hazard, at the service connection, or discontinuance of the service. INTRODUCTION AGENDA ITEM #8C JUNE 14, 2004 A cross-connection is defined in the rules of the Department of Environmental ~egu~isr~ Protection (B€~DEP), of the State of Florida, Chapter 4262-550 as "Any physical arrangement whereby a public water supply is connected, directly or indirectly with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which contains or may contain contaminated water, sewage or other waste or liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water supply as the result of backflow. By-pass arrangements, jumper connections, removable sections, swivel or changeable devices and other temporary or permanent devices through which or because of which backflow could occur are considered to be cross-connections." Consequently, either cross-connections or the chance of backflow must be eliminated to prevent degrading the high quality of water that water purveyors strive to maintain. Cross-connection control programs, as administered by water purveyors, are relatively new to Florida. Initially, the primary responsibility for safeguarding water quality on private property was left to local health agencies and building and inspection departments. Then, beginning with the Safe Drinking Water Act, signed by President Ford on December 16, 1974, a chain of laws and regulations evolved that resulted in the State requirement (Florida Safe Drinking Water Act, Sections 403.850-403.864, Florida Statutes) for all the public water systems to have across-connection control program. Contained within the Rules of Department of Environmental Regulation (DER), Chapter 17-22, the State of Florida, on November 9, 1977, adopted the following policy: "Community water systems are required to establish a routine cross-connection program for the purpose of defecting and preventing cross-connections that create an imminent and substantial ~"" danger to the public health by and from contamination due to the cross-connection. Upon detection of a prohibited cross-connection, both community and non-community water systems shall either eliminate the cross-connection by installation of an appropriate backflow prevention device ~* acceptable to the Department (DER) or discontinue service until the contaminate source is eliminated."(17-22.107(4)b., Florida Administrative Code.) ~„ The most recent version of DEP Rule now states "Community water systems... shall establish and implement a routine cross-connection control program...." A statement is also included in the rule that "This program shall include a written plan that is developed using recommended practices of the American Water Works Association set forth in Recommended Practice for8ackflow Prevention and Cross-Connection Control. AWWA Manual M14..." ,~ ~. ~ » In compliance with this mandate, the following is the City of Atlantic Beach, Public aAle~s-Utilities Department, Policy on Cross-Connection Control. We urge you to acquaint yourself with the policies and information presented in this manual. It is only through the education and commitment' of persons like yourself that we can control the hazards presented by cross-connections within our public drinking water supply. The Public `nibUtilities Department stands behind this policy and its enforcement and will offer its assistance to all who share the responsibility of safe water. }I AGENDA ITEM #8C JUNE 14, 2004 PART 1 - Overview 1.01 PURPOSE The purpose of this Policy is to protect the public potable water supply of the City of Atlantic Beach from the possibility of contamination. To promote the elimination or control of existing cross- connections, actual or potential, between its customers' in_plant plumbing fixtures and industrial piping and the public water supply; and to provide for the maintenance of a continuing program of cross-connection control which will systematically and effectively prevent the contamination of the potable water distribution system. More exactly, the Policy is intended to prevent delivered water- waterthat has passed beyond the public water system and into the private distribution systems of consumers -from re-entering the public distribution system and being subsequently delivered to consumers and to allow persons active in piping design and installation to incorporate and install appropriate backflow prevention devices correctly. 1.02 CAUSES OF BACKFLOW The causes of backflow cannot usually be eliminated completely since backflow is often initiated by accidents or unexpected circumstances. However, some causes of backflow can be partially controlled by good design and informed maintenance. Listed below are the major causes of backflow as outlined under the two types of backflow - backsiphonage and backpressure. A. BACKSIPHONAGE - Backsiphonage is caused by reduced or negative pressure being created in the supply piping. The principal causes of backsiphonage are: 1. Line repair or break which is lower than a service point. This will allow negative pressures to be created by water trying to flow to a lower point in the system. ~" 3:2. Undersized piping if water is withdrawn from a pipe at a very high velocity, the pressure in the pipe is reduced and the pressure differential created can cause water to flow into the pipe from a contaminated source. 3. Lowered pressure in water main due to high water withdrawal rate such as fire fighting, water main flushing, or water main breaks. 4. Reduced supply main pressure on suction side of a booster pump. ~,,, B. BACKPRESSURE - Backpressure may cause backflow to occur where a potable water system is connected to anon-potable system of piping, and the pressure in the non-potable system exceeds that in the potable system. The principal causes of backpressure are: Booster pump systems designed without backflow prevention devices. 2. Potable water connections to boilers and other pressure systems without backflow prevention devices. (2) AGENDA ITEM #8C JUNE 14, 2004 3. Connections with another system (such as a private well with a pump) which may, at times, have a higher pressure. ~4. Water stored in tanks or plumbing systems which by virtue of their elevation would create head sufficient to cause backflow if pressure were lowered in the public system. PART 2 -Responsibility 2.01 CROSS-CONNECTION PROGRAM The responsibilities of the Cities' rLs Cross-Connection Control Program in accordance with State Law Chapter X262-555 are as follows: 1. To protect the City of Atlantic Beach Public Water Supply from the possibility of contamination ~"" by isolating within its consumers' private water systems, contaminants or pollutants which could, under adverse conditions, backflow through uncontrolled cross-connections into the public water system. 2. To eliminate or control existing cross-connections, actual or potential, between the consumer's in-plant potable water system(s) and non-potable water system(s) plumbing fixtures, and industrial piping systems. 3. To provide a continuing inspection program of cross-connection control, which will systematically and effectively control all actual or potential cross-connections which may be installed in the future. 2.02 CUSTOMERS The customer's responsibility starts at the point of delivery from the public potable water system and includes all of his water systems. The customer, at his own expense, shall install, operate, test and ~ maintain approved backflow prevention devices, as directed by the City of Atlantic Beach-1AFateF Public Utilities Department. The customer shall maintain accurate records of tests and repairs made to backflow prevention devices and provide the !t"' Public Utilities Department with copies of such_ records. The records shall be on forms approved or provided by the Department. In the event of accidental pollution or contamination of the public or consumer's potable water system due to backflow on or from ~. customer's premises, the owner shall promptly take steps to confine further spread of pollution or contamination within the customer's premises, and shall immediately notify the Biv+s+er~Public Utilities Department of the hazardous condition. 2.03 BACKFLOW PREVENTION (BFP) DEVICE INSTALLERS Device assembly installation is to be conducted by a plumber. A certified technician must conduct testing of backflow assembly. The owner plumber or a certified repairman may do repairs as needed A passing BFP test report must be submitted to the City of Atlantic Beach (COAB) Cross Connection Control Administrator after any repairs or device replacement. ""` Active certification and inclusion on the municipal list of approved testers is mandated by municipal policy AWWA/Treeo/ USCFCCCHR certificates are acceptable. Test Units must also meet with USCFCCCHR approval and should be calibrated annually. AGENDA ITEM #8C JUNE 14, 2004 Installer is required to furnish the following information to the Cross-Connection Control Pro raq_ m im_ mediately after a reduced pressure principle backflow preventer (RP), double check valve assembly (DCVA) or pressure vacuum breaker (PVB) is installed: 1) service address where device is located, 2) owner, 3) description of device's location and size, 4) date of installation, 5) type of device, 6) ® manufacturer, 7) model number, and 8) serial number. ~* ~ ~ AGENDA ITEM #8C JUNE 14, 2004 • > > > > > > ~ > PART 3 -INSPECTIONS 3.01 FREQUENCY Due to changes in models or components of equipment, methods of manufacturing and additions to plants, buildings, etc., water use requirements undergo continual change. As a result, new cross- "" connections may be installed and existing protection may be by-passed, removed, or otherwise ineffective; therefore, an annual or biennial detailed inspection by the customer of all water usage is required. 3.02 PROPOSED CONSTRUCTIONS All new construction plans and specifications for industrial or commercial facilities shall be reviewed by the City of Atlantic Beach's Public aAFsr~s-Utilities Department to determine the degree of possible cross-connections hazard. At tf~that time, backflow prevention requirements in accordance with this policy will be made. 3.03 NEW AND EXISTING FACILITIES In order to determine the degree of hazard to the public potable water system, a survey will be made of the consumer's presently installed water system. This survey need not be a detailed inspection of the location or disposition of the water lines, but can be confined to establishing the water uses on the premises, the existence of cross-connections, and the availability of auxiliary or used water supplies. On-_site inspections are made of new and existing facilities and should any devices or plumbing changes be required, afollow-up inspection will be made of the same facilities at a later date. PART 4 - DEFINITIONS AIR-GAP SEPARATION -The term air-gap separation shall mean a physical separation between the free-flowing discharge end of a potable water supply pipeline and an open or non-pressure receiving vessel. An approved air-gap separation shall be a distance of at least two (2) times the diameter of the supply pipe measured vertically above the top rim of the vessel - with a minimum distance of one (1) inch. ~" APPROVED: Accepted by the Public Utilities Department as meeting an applicable specification and approved by the Department of Environmental ~Ieg~lafier~Protection, State of Florida, or their designee. ~" (4) AGENDA ITEM #8C JUNE 14, 2004 ATMOSPHERIC VACUUM BREAKER: An approved device consisting of a check valve and an air inlet to relieve a vacuum. It shall effectively shut off the reverse flow of water when a negative +~. pressure exists on the supply side of the device. AUXILIARY WATER SUPPLY: Any water supply on or available to the premises other than the ,~„ purveyor's approved public potable water supply. These auxiliary waters may include water from a private nonpotable water supply or any natural source(s) such as a well, spring, river, stream, harbor, etc., or "used waters" or "industrial fluids". These waters may be contaminated or they may be objectionable, and constitute an unacceptable water source over which the water purveyor does "~ not have sanitary control. BACKFLOW: The flow of water or other liquids, mixtures or substances under pressure into the distribution pipes of a potable water supply system from any source or sources other than its intended source. BACKFLOW PREVENTION DEVICE: A backflow prevention device shall mean any effective device, method or construction used to prevent backflow into a potable water system. The type of device used should be based on the degree of hazard, either existing or potential. BACKFLOW PREVENTION DEVICE -APPROVED: The term approved backflow prevention device shall mean a device that has met the requirements of one or more of the following standards: AVW1/A - C-506Standard for Backflow Prevention Devices, Reduced Pressure Principle and Double Check Valve Types. ASSE - 1001 Atmospheric Type Vacuum Breakers ASSE - 1011 Hose Connection Vacuum Breakers ASSE - 1020 Pressure Type Vacuum Breakers ASSE - 1024 Dual Check Type Backflow Preventer (Residential Use Only) ASSE - 1013 Reduced Pressure Principle Back Pressure Backflow Preventers ASSE - 1015 Double Check Valve Type Back Pressure Backflow Preventers USC-F000 University of Southern California Foundation for Cross-Connection Control and Hydraulic Research BACKFLOW PREVENTION DEVICE TECHNICIAN-CERTIFIED The term certified backflow prevention device technician shall mean a person who has proven his competency to the satisfaction of the City of Atlantic Beach's Public aAl~s-Utilities Department. ~"' Each person who is certified to make competent tests or to repair, overhaul and make reports on backflow prevention devices shall be conversant with applicable laws, rules and regulations and shall have attended and successfully completed the TREED (Training, Research, and Education for Environmental Occupations) Certification Program for Backflow Prevention Device Testers at the University of Florida, or other acceptable programs to the Public aAFe#s-Utilities Department. Due to frequent occupancy change, a minimum commercial service requirement of Reduced Pressure ~„ backflow prevention has been implemented. (5) ~+• ~~ AGENDA ITEM #8C JUNE 14, 2004 BACKSIPHONAGE: The flow of water or other liquids, mixtures or substances into the distributing pipes of a potable water supply system from any source other than its intended source caused by the reduction of pressure in the potable water system. ~,,. BACKPRESSURE: Backpressure shall mean any elevation of pressure in the downstream piping system (by pump, elevation of piping, or steam and/or air pressure) above the supply pressure at the point of consideration wthat would cause or tend to cause, a reversal of the normal flow. ~• CONTAMINATION: An impairment of the quality of the potable water by any solid, liquid, or '"' gaseous compounds or mixtures to a degree which would create an imminent danger to the public health, or would create an unacceptable taste, odor or color to the potable water. Cross Connection Control Administrator: The Cross Connection Control Adminsitrator of the City of Atlantic Beach is invested with the authority and responsibility for the implementation of an effective cross-connection program and for the enforcement of the provisions of this policy. CROSS-CONNECTION: Any physical connection or arrangement of piping or fixtures between two otherwise separate piping systems, one of which contains potable water and the other nonpotable ~" water or industrial fluids of questionable safety, through which, or because of which, backflow or backsiphonage may occur into the potable water system. A water service connection between a public potable water distribution system and a customer's water distribution system which is cross- '' connected to a contaminated fixture, industrial fluid system or with potentially contaminated supply or auxiliary water system, constitutes one type of cross-connection. Other types of cross- connections include connectors such as swing connections, removable sections, four-way plug valves, spools, dummy sections of pipe, swivel or changeover devices, sliding multipart tube, solid connections, etc. ~„ DOUBLE CHECK VALVE ASSEMBLY: An assembly composed of two single, independently acting, check valves*, including tightly closing shut-off valves located at each end of the assembly. *A valve that is drip-tight in the normal direction of flow when the inlet pressure is one p.s.i. and the ~, outlet pressure is zero. The check valve shall permit no leakage in a direction reverse to the normal flow. The closure element (e.g., clapper) shall be internally weighted or otherwise internally loaded to promote rapid and positive closure and suitable connections for testing the watertightness of each check valve. HAZARD-DEGREE OF: The term degree of hazard is a qualification of what potential and actual harm may result from cross-connections within a water using facility. Establishing the degree of hazard is directly related to the type and toxicity of contaminates that could feasiblely enter the public water supply system and is determined by the Public Utilities Department. HAZARD-HEALTH: The term health hazard shall mean an actual or potential threat of con- tamination or pollution of a physical or toxic nature to the public potable water system or the consumer's potable water system to such a degree or intensity that there would be a danger to health. AGENDA ITEM #8C JUNE 14, 2004 INDUSTRIAL PIPING SYSTEM -CONSUMER'S: The term consumer's industrial piping system shall mean any system used by the consumer for transmission of or to store any fluid, solid or ~* gaseous substance other than an approved up blic water supply. Such a system would include all pipes, conduits, tanks, receptacles, fixtures, equipment and appurtenances to produce, convey or store substances w~+sk~-that are or may be polluted or contaminated. REDUCED PRESSURE BACKFLOW PREVENTER: A device containing within its structure a minimum of two independently acting, approved check valves, together with an automatically operating pressure differential relief valve located between the two check valves. The first check valve reduces the supply pressure a predetermined amount so that during normal flow and at cessation of normal flow the pressure between the check valves shall be less than the supply pressure. In case of leakage of either check valve, the differential relief valve, by discharging to atmosphere, shall operate to maintain the pressure between the check valves less than the supply pressure. The unit shall include tightly closing shut-off valves located at each end of the device, and each device shall be fitted with properly located test cocks. VACUUM BREAKER -PRESSURE TYPE: A pressure vacuum breaker is similar to an atmospheric vacuum breaker except that the checking unit "poppet valve" is activated by a spring. This type of vacuum breaker does not require a negative pressure to react and can be used on a pressure side of a valve. ,~, WATER PURVEYOR: The term water purveyor shall mean the owner or operator of the public potable water system supplying an approved water supply to the public. The utility shall be one that is operating under a valid permit from the Department of Environmental I~eg~atier~Protection. As used herein the terms water purveyor and City's Public Utilities ~ Department may be used synonymously. WATER SYSTEM -CUSTOMER'S: The term customer's water system shall include any water ~" system located on the consumer's premises, whether supplied by a public potable water system or an auxiliary water supply. The system or systems may be either a potable water system or an industrial piping system. WATER-USED: Any water supplied by a Water Purveyor from a public potable water system to a customer's water system after it has passed through the point of delivery and is no longer under the sanitary control of the Water Purveyor. PART 5 -Cross-Connection Hazards and Required Protections 5.01 FACILITIES ~ TYPE OF BACKFLOW PROTECTION REQUIRED: An approved backflow prevention device of the type designated shall be installed on each water service connection to the following types of facilities.

(i.e., parks, play fields, cemeteries) Others specified by the ~ Public Utilities Department * INSTALLATIONS REQUIRING CONTINUOUS SERVICE: PARALLEL INSTALLATION All backflow prevention devices with test cocks are required to be tested with a minimum frequency ~ of once per year. Testing requires a water shutdown usually lasting five (5) to twenty (20) minutes. For facilities that require an uninterrupted supply of water, and when it is not possible to provide water service from two separate meters, provisions shall be made fora "parallel installation" of backflow prevention devices. Multi-story buildings which have a number of flushometer toilets should be equipped with parallel devices. Experience has shown if the water supply is shut off to this type of building, flushometers may have to be manually reset. During testing one device is left on while the other is being tested. Usually the two devices are sized one device size smaller than the service line, e.g. one 2 inch device or two 1-1 /2 inch devices, one 8 inch device or two 6 inch devices. The Public Utilities Department will not accept an unprotected bypass around a backflow preventer when the device is in need of testing, repair or replacement. ** HEALTH HAZARD; SYSTEM HAZARD; POLLUTIONAL HAZARD "Health hazard" means any condition, device, or practice in a water system or its operation that creates, or may create, a danger to the health and well-being of users. The word "severe" as used ~" to qualify "health hazard" means a hazard to the health of the user that could reasonably be expected to result in significant morbidity or death. "System hazard" means a condition posing an actual or potential threat of damage to the physical properties of the public water system or a potable consumer's water system. "Pollutional hazard" means a condition through which an aesthetically objectionable or degrading material not dangerous to health may enter the public water system or a potable consumer's water system. ***EXTERMINATING COMPANIES All tanks, tank trucks, and spraying apparatus used to convey pesticides in an exterminating process ~" are required to use only designated-protected potable water fill locations. Filling with potable water at unspecified locations or private residences is prohibited. All filling locations will consist of over- head piping arrangements with correctly installed pressure vacuum breakers. If, for any reason, an ~"" overhead piping arrangement cannot be used, a reduce pressure zone backflow preventer must be installed on the fill line. All filling locations must be approved by the ~"~~+er nip+rih„+i.,., 9tv+sienPublic Utilities Department.

AGENDA ITEM #8C JUNE 14, 2004 NOTE: Single check valves will not be accepted as a means to protect the potability of drinking water and therefore may only be used to prevent backflow which would effect the functioning of a plumbing system, such as to prevent recirculation of potable hot water. Where single check valves are improperly used, they will be required to be replaced by an appropriate approved backflow prevention device. VACUUM BREAKERS (vacuum relief valves) designed to prevent collapse or implosion of a steam- ,„ heated pressure vessel when being cooled are not acceptable devices for protection against backflow in potable water lines. PART 6 -Testing of Backflow Preventers It shall be the duty of the customer-user at any premises where reduce pressure backflow prevention devices (RP), double check valve assemblies (DCVA), and pressure vacuum breakers (PVB) are installed to have thorough inspections and operational tests made at least once a year or more often in those instances-where inspections indicate a need. These inspections and tests shall be at the expense of the water user and be performed by the device manufacturer's representative, or by a certified device technician. The water purveyor_ will notify the customer-user when tests are required and supply the necessary test forms and instructions.-These forms will be completed and returned to the water purveyor by the date indicated. PART 7 -Penalties for Non-Compliance 7.01 TERMINATION OF SERVICE ,~ A written notification detailing all cross-connections found during the inspection will be sent to the owner or authorized agent of the owner of the building or premises, stating that corrections must be made and setting a reasonable time for compliance. Upon failure of the owner or authorized agent ~ of the owner of the building or premises to have the defect(s) corrected by the specified time the water purveyor shall cause the water service to the building or premises to be terminated. The water purveyor shall cause discontinuance of water service if a required backflow prevention device has been bypassed or failed to be tested or properly maintained as required by this policy statement. ~"" -The water purveyor shall also cause discontinuance of water service if an air-gap separation system is compromised. 7.02 MONETARY PENALTIES Violations of this policy, if not corrected after due notice, will be referred to the Code Enforcement ~. Board of the City of Atlantic Beach. Under Florida State Statute 162.09, the Code Enforcement Board may impose fines of up to $250.00 per day for a first violation and $500.00 per day for a repeat violation.

No person shall interconnect a privately owned water system to the city's water system. (Code 1970, § 27-16) Sec. 22-33. Prohibited acts. No person shall connect or turn on any water service or tap or make any alteration to any main or distribution pipe of the city's water system or in any way interfere with or molest any of the wells, reservoirs, basins or water in the same, or permit any connection or tapping to be made to the city's water system on his premises or the premises occupied by him or knowingly use city water from unauthorized connections. (Code 1970, § 27-17) Sec. 22-42. Definitions. Cross connection means any physical arrangement whereby a public water supply is connected, directly or indirectly, with any other water supply system, sewer, drain, lawn sprinkler, conduit, pool, storage reservoir, plumbing fixtures, appliances, or other devices which contain or may contain contaminated water, sewage or other waste or liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water supply as the result of backflow. Bypass arrangements, jumper connections, removable sections, swivel or changeable devices and other temporary or permanent devices through which or because of which backflow could occur aze considered to be cross connections. (Ord. No. SO-92-50, § 1, 10-12.92) Sec. 22.43. Cross connections; backflow devices. (a) No consumer of water from the city water system shall have a cross connection or potential cross connection either inside or outside of any building or buildings without a backflow prevention device being installed to prevent any and all backflow. (b) Only the following are considered to be backflow prevention devices and shall be installed in agreement with and under supervision of the supplier of water or his designated representative: fl) Air gap separation. A physical separation between the free-flowing dischazge end of a ~ potable water supply pipeline and an open or nonpressure receiving vessel. This gap must be at least double the diameter of the supply pipe measuresd vertically above the rim of the vessel and in no case less than one (1) inch. (2) Reduced pressure backflow preventer. A device containing within its structure a min• imam of two (2) independently acting, approved check valves, with an automatically operating pressure differential relief valve located between the t~vo (2) check valves that will discharge to the atmosphere if the check valves should fail. This unit shad include tightly closed shut•offvalves located at each end of the device and each device shall be fitted with properly located test cocks. AGENDA ITEM #8C JUNE 14, 2004 (3) Atmospheric vacuum breaker. This device is operated by atmospheric pressure in combination with the force of gravity. The unit is designed to work on a vertical plane only. The one moving part consists of a poppet valve which must be carefully sized to the slide in a guided chamber and effectively shut off the reverse flow of water when there is a negative pressure. {4) Pressure vacuum breaker. This device is similar to an atmospheric vacuum breaker, except that the checking unit "poppet valve" is activated by a spring and does not require a negative pressure to react. (5) Double check-valve assembly. An assembly composed of two (2) single, independently acting -drip-tight check valves, including tightly closing shut-off valves at each end and suitable connections for testing the water tightness of each check valve. (c) The city or its representatives with proper identification may enter at any time inside or outside of any building or buildings for the purpose of checking for cross connections. If a cross connection or potential cross connection is found, the city shall have the right to discon- tinue water services until the problem has been corrected by elimination or until a proper backflow prevention device has been installed. All backflow prevention devices will be checked periodically by a city representative to insure proper operation. (d) These provisions relative to a cross connection have been established for the protection iie1 of ail the inhabitants of the city and to comply with Chapter 17-22.107(4), Florida Adminis- trative Code. (e) All water services and plumbing fixtures shall conform to the latest edition of the City of Atlantic Beach Cross Connection Control Policy Manual. (Ord.

[John.R.Sowerby@dep.state.fl.us] Sent: Thursday, April 29, 2004 5:47 PM To: Kaluzniak, Donna Cc: Hoofnagle, Van; Cordova, Ed Subject: RE: Cross Connection Control Follow Up Flag: Follow up Flag Status: Flagged 3cchecklist.doc Donna, Van Hoofnagle has asked me to reply to your April 7 e-mail about cross-connection control. ""' First, I apologize for taking so long to reply to your e-mail. Your e-mail was originally forwarded to me at a time when I was out of the office, and it got lost in a-sea of other e-mail. It is, and always has been, the Department's intent that all community water systems have a real cross-connection control program that the water system implements. Prior to August 28, 2003, Florida Administrative Code (FAC) subsection 62-555.360(2) read, "Community water systems...shall ESTABLISH a...cross-connection control program...." The word "establish" was intended ~~ to mean "introduce and enforce. However, to make our rules more clear and more enforceable, we decided to insert the phrase "and implement" after the word "establish" in FAC subsection 62-555.360(2) and did so effective August 28, 2003, so that FAC subsection 62-555.360(2) now reads, "Community water systems...shall ESTABLISH AND IMPLEMENT a...cross-connection control program...." This clarification applies to all community water systems and in no way implies that community water systems in existence before August 28, 2003, are, or ever were, exempt from having to implement their cross-connection control program. FAC subsection 62-555.360(2) requires, that cross-connection control programs be consistent with the recommendations in American Water Works Association (AWWA) Manual M14, Recommended Practice for Backflow Prevention and Cross-Connection Control. AWWA Manual M14, which is recognized nationally and represents standard practice for the water works industry, recommends installation of a proper backflow preventer at the potable water service connection to certain premises or systems that present a hazard to the public water system, including premises where there is an auxiliary water system such as a private well Auxiliary water systems present a very real hazard to public water systems. Auxiliar water s stems enerall contain nonpotab e water or water of unknown qualit and it is common for owners of auxi iary water systems to temporarily or permanentl connect their auxiliar water sys em o eir potab e water s stem to rovide su lementa w eir auxi iary water system when their auxiliary water supply is insufficient or when their auxiliary water pump fails. It is usually ___ difficult for a water supplier to be certain that there is no current connection between a customer's auxiliary water system and potable water system, and even if a water su lier can be certain that there is no connection TODAY, the water supplier cannot be "certain that t ere wil e no connection TOMORROW; thus, the recommendation for a backflow preventer stand: regardless of whether there is a known current connection between a customer s auxi iary water system and potable water system. I am attaching a checklist that may help you in making sure that your updated cross-connection control program complies with FAC Rule 62-555.360 and AWWA 1 ~* AGENDA ITT1~1 #:8C JTJNE 1=t, 2004 a•• Manual M14.
