PURPOSE This Cross Connection Control Program ("Program") manual has been prepared to set forth guidelines and procedures to be used by the Town of Gulf Stream ("Town")' to establish and carry out an ongoing cross - connection control program. A successful cross -connection control program reduces the risk of contamination or pollution of the Town's public water supply system. II. RESPONSIBILITIES The United States Environmental Protection Agency has jurisdiction over the public health aspects of drinking water supply. In Florida, the authority to regulate public water supplies has been delegated to the Florida Department of Environmental Protection ("FDEP"). In Palm Beach County, the Palm Beach County Health Department has been delegated the responsibility to monitor and enforce Florida Statutes that regulate public water supplies and suppliers (purveyors) by the Florida Legislature through the FDEP. Within the service area, when a person or entity establishes a service account to purchase water from the Town, that person or entity becomes a water customer ("consumer") of the Town and as a condition of continued service shall comply with all rules and regulations of the Town in regard to the water system. Consumer The consumer owns and is responsible for ensuring the integrity of the system piping and water downstream of the water meter. It is the responsibility of the consumer to avoid cross -connections to their portion of the water line and/or to install appropriate backflow devices. The consumer shall own any backflow device required by this Program and shall also be responsible for its maintenance/repair and replacement. Records of all installation, maintenance/repair and replacement shall be provided by the consumer to the Town. Town The Town is responsible for the inspection and testing of backflow prevention devices and maintaining records related to the administration of this Program. The Town shall be responsible for disconnecting service as outlined in the Town Code, Section 34-40 Backflow and Cross Connection Control Policy, upon failure of the consumer to comply with the requirements of this Program. III. LEGAL AUTHORITY This Program is authorized by Town of Gulf Stream Ordinance No. 18/5, codified at Chapter 34, Utilities; Article II, Water Service; Section 34-40 Backflow and Cross Connection Control Policy pursuant to: the Florida Administrative Code ("F.A.C.") Rule 62-555.360; the American Water Works Association ("AWWA') Manual M14, Recommended Practice for Backflow Prevention and Cross Connection Control; and the Safe Drinking Water Act of 1974. IV. POLICY 1. Water System 1.1 The water system shall be considered as made up of two parts: the Town's system and the consumer's system. ' As used herein, "Town" refers to the Town of Gulf Stream and, where applicable, the Town Manager or designee utilized in performing the functions outlined in this Program. Cross Connection Control Program Page 3 of 10 Town of Gulf Stream October 2018 1.2 The Town's system shall include all those facilities of the water system under the complete control of the Town, up to the point where the consumer's system begins beyond the water meter. 1.3 The consumer's system shall include those parts of the facilities beyond the water meter that are utilized in conveying Town delivered domestic water to points of use. 2. Backflow Prevention 2.1 No water service connection to any premises shall be installed or maintained unless the water supply is protected as required by the state laws and regulations and this Program. Service of water to any premises shall be discontinued by the Town if a backflow -prevention assembly required by this Program is not installed, tested, and maintained, or if it is found that a backflow -prevention assembly has been removed, bypassed, or if an unprotected cross -connection exists on the premises. Service will not be restored until such conditions or defects are corrected. 2.2 The consumer's system should be open for inspection at all reasonable times to the Town to determine whether cross -connections or other structural or sanitary hazards, including violations of these regulations, exist. When such a condition becomes known, the Town shall deny or immediately discontinue service to the premises by providing for a physical break in the service line until the consumer has corrected the condition(s) in conformance with this Program and applicable laws relating to plumbing and water supplies and the regulations adopted pursuant thereto. 2.3 An approved backflow -prevention assembly shall be installed on each service line in a consumer's water system at or near the property line or immediately inside the building being served; but in all cases, before the first branch line leading off the service line wherever the following conditions exist: a. In the case of premises having an auxiliary water system that is not, or may not be, of safe bacteriological or chemical quality and that is not acceptable as an additional source by the Florida Department of Environmental Protection, the public water system shall be protected against backflow from the premises by having an approved backflow -prevention assembly installed in the service line, appropriate to the degree of hazard. b. In the case of premises having either: (1) internal cross -connections that cannot be permanently corrected and controlled; or (2) intricate plumbing and piping arrangements or where entry to all portions of the premises is not readily accessible for inspection purposes, making it impracticable or impossible to ascertain whether or not dangerous cross -connections exist; the public water system shall be protected against backflow from the premises by having an approved backflow -prevention assembly installed in the service line 2.4 The type of protective assembly required under this program shall depend upon the degree of hazard that exists as follows: a. Hazard (Health). Any condition, device, or practice in the water supply system and its operation which could create, or in the judgment of the Town, may create a danger to the health and well- being of the Town's water customers. An example of a health hazard is a structural defect, including cross -connection, in a water supply system. b. Hazard (plumbing). A plumbing type cross -connection in a consumer's potable water system or to the potability of the public or the consumer's potable water system but which would constitute a nuisance or be aesthetically objectionable or could cause damage to the system or its appurtenances, but would not be dangerous to health. Cross Connection Control Program Page 4 of 10 Town of Gulf Stream October 2018 c. Hazard (pollution). An actual or potential threat to the physical properties of the water system or to the potability of the public or the consumer's potable water system but which would constitute a nuisance or be aesthetically objectionable or could cause damage to the system or its appurtenances, but would not be dangerous to health. d. Hazard (system). An actual or potential threat of severe damage to the physical properties of the public potable water system or the consumer's potable water system or of pollution or contamination which would have a protracted effect on the quality of the potable water in the system. 2.5 Approved Devices and Testing. Any "approved backflow -prevention assembly" required or referenced herein shall be a design, model and size that has been manufactured and approved in full conformance with the standards established by the American Water Works Association as follows: ANSI/AWWA C510-89 — Standard for Double Check Valve Backflow -Prevention Assembly, and AWWA C511-89 — Standard for Reduced -Pressure Principle Backflow Prevention Assembly, and have met completely the laboratory and field performance specifications of the Foundation for Cross -Connection Control and Hydraulic Research ("FCCCHR") of the University of Southern California established by "Specification of Backflow -Prevention Assemblies" — Sec. 10 of the most current issue of the Manual of Cross -Connection Control. Said AWWA and FCCCHR standards and specifications are hereby adopted by this Program. Final approval shall be evidenced by a "Certificate of Approval" issued by an approved testing laboratory certifying full compliance with said AWWA standards and FCCCHR specifications. V. DEFINITIONS 1. Auxiliary Water System A pressurized system of piping and appurtenances using water other than the potable water being supplied by the Town such as water from any natural source such as a well, pond, lake, or spring. This does not include any water recirculation or treatment system for a swimming pool, hot tub, or spa. 2. Backflow The flow of water or other foreign liquids, gases, or other substances into the distribution system of a public water supply from any source other than the intended. 3. Backflow Prevention Device Backflow prevention devices, listed in an increasing level of protection, include the following: a dual check device (DuC); a double check valve assembly (DC) or double check detector assembly (DCDA); a pressure vacuum breaker assembly (PVB); a reduced -pressure principle assembly (RP) or reduced - pressure principle detector assembly (RPDA); and an air gap. 4. Back Siphonage Backflow resulting from negative or less than atmospheric pressure in the water system. 5. Back -Pressure A condition in which the consumer's system pressure is greater than the supplier's system pressure. 6. Containment A method of backflow prevention which requires a backflow prevention device at the water service entrance. 7. Cross -Connection Any connection or structural arrangement between a public or consumer's potable water system and any non -potable source or system through which backflow can occur. Cross Connection Control Program Page 5 of 10 Town of Gulf Stream October 2018 8. Fixture Isolation A method of backflow prevention in which a backflow prevention device is located to correct a cross - connection at an in -plant unit rather than at the water service entrance. 9. Water Service Entrance That point in the consumer's water system beyond the water meter, usually close to the property line. VI. CATEGORIES OF CUSTOMER The table below lists the various categories of customers present in the Town and the minimum type of backflow prevention device that will be required under this Program. This table may not be all inclusive and for any type of facility not listed therein, the Town shall determine the appropriate type of device to be installed in accordance with F.A.C. Table 62-555.360-2 and applicable law. NOTE: In all cases an approved physical air gap may take the place of a backflow prevention assembly. ' The Town shall ensure that backflow protection commensurate with the degree of hazard is provided at or for the service connection from its fire hydrant.

Cross Connection Control Program Page 6 of 10 Town of Gulf Stream October 2018 VII. ADMINISTRATION 1. Records The Town shall maintain a current inventory and location of required backflow protection devices, and records of the installation, inspection/testing, and repair of backflow prevention devices. Records required to be maintained pursuant to F.A.C. Rule 62-550.720(3) shall be maintained by the Town for ten (10) years in electronic or paper format. 2. Plan Review and Inspection a. The Town shall review construction plans or other pertinent records to establish the category of customer and the required backflow protection as follows: i. Newly constructed service connections shall be evaluated prior to the Town supplying water to the service connection. ii. Existing water service connections shall be evaluated once it is discovered that a prohibited or inappropriately protected cross -connection is present; an auxiliary water system is discovered on the consumer's premises; or whenever the consumer's premises is altered under a building permit in a manner that could change the backflow protection required. Once the connection is evaluated, the Town will classify the level of hazard and category of customer in accordance with this Program and applicable law, and provide a list of approved devices to the consumer. b. The consumer shall allow his or her property to be inspected for possible cross -connections and for the testing of backflow prevention devices by the Town. c. After inspection of plans or premises the Town shall inform the property owner by written notice of any cross -connections, suggest ways of correcting the problem, and will establish a time limit for the correction to be made. d. When applying for a new service the consumer shall inform the Town if there are any possible cross -connections existing or proposed. Prior to activation of all new water services and new construction, compliance with this Program and all applicable laws shall be mandatory. e. The Town reserves the right to inspect all cross -connections. The consumer shall comply with any required changes as a result of the inspections. Failure to do so will result in termination of water service. L When new building construction permits are issued by the permitting agency, plans shall be reviewed from a cross -connection control perspective and address cross connection protection. This will avoid potential arguments when water service application is made. Procedures shall include follow-up site inspection when the construction is completed. Fire protection systems must also be inspected to protect against these potential sources of cross -connections. For multi -use developments where the ultimate hazard is unknown the designer of the plumbing systems must address the use of a Reduced Pressure Principle backflow preventer. Care should be taken in sizing to ensure that it does not reduce fire protection ratings or reduce domestic water main pressures below the minimum needed. Typically the size of the device should match the size of the water main. 3. Installation a. After being informed by written notice from the Town, the consumer, at their own expense, shall install a backflow prevention device listed and approved by the Town. Newly installed devices shall be inspected to ensure proper installation. Cross Connection Control Program Page 7 of 10 Town of Gulf Stream October 2018 b. The manner of installation shall be according to manufacturer's specifications and approved by the Town. Installation criteria shall be consistent with installation criteria in AWWA Manual M14 as incorporated into subsection 62-555.360(2) F.A.C. Backflow protection shall be installed as close as practical to the water meter, and in all cases before the first distribution line off the consumer's water service line. Without exception, no connections shall be allowed between the service entrance at the consumer's property line and the backflow device inlet. c. The Town prohibits any interconnections by the consumer within the consumer's plumbing system which would create a real or potential cross -connection with the public water system thereby creating a public health hazard. d. All dual check valves shall be refurbished or replaced every 10 years. 4. Testing a. All testable devices are required to be properly maintained and shall be tested annually by a certified backflow device tester approved by the Town, or biennially if the consumer's water meter diameter is 2 inches or less and services a building or premises containing only dwelling units. Required air gaps shall be inspected annually. In instances where the Town deems the hazard to be great enough, inspections and testing may be required at more frequent intervals. b. Backflow prevention devices shall be inspected and tested by the Town at the consumer's expense. All newly installed devices shall be tested upon installation and prior to official operation. The maintenance of approved devices shall be the responsibility of the consumer. c. The Town shall notify the consumer when required testing of a device is to be performed and provide an approximate date for the test. The notification will include an explanation of responsibilities and requirements regarding completion of the test. d. If a device fails a test, the Town shall immediately inform the consumer and require maintenance or replacement and re -testing. Devices shall be maintained, repaired, and replaced at the expense of the consumer. The consumer shall provide all records of repair, overhaul, and replacement to the Town. e. Malfunctioning devices must be repaired immediately. If removal is necessary, service must be shut down. The device is to be retested immediately after any type of maintenance or reolcation. 5. Exemptions Any existing backflow prevention device in service at the time this program goes into effect shall be allowed to continue in service until: a. The device protecting the cross -connection is inadequate for the degree of hazard; b. The device is moved from the present location; c. The device fails when tested; or d. The device malfunctions and requires more than routine maintenance, as determined by the Town. 6. Compliance a. Once discovered, all cross connections that are deemed by the Town to be a high hazard shall be immediately eliminated or protected by a proper backflow device. The Town may immediately terminate service if the cross connection cannot be eliminated or protected. b. All cross connections that are deemed by the Town to be a low hazard shall be eliminated or protected by a proper backflow device within 90 days of discovery. Subsequent actions, Cross Connection Control Program Page 8 of 10 Town of Gulf Stream October 2018 including warnings and termination of water services, shall be in accordance with the Enforcement Procedures in the Town Code's Backflow and Cross Connection Control Policy. c. Failure to comply with these regulations, procure and install the proper device, or repair a malfunctioning device may lead to termination of service until compliance has been achieved. d. Should the Town deem the connection to be immediately dangerous to the public's health, the service will be immediately disconnected and will remain off until such time the cross connection is eliminated or adequately protected by a proper and approved backflow device. 7. Complaints and Emergencies a. Consumer Complaints Consumer complaints can be an indication of a backflow incident and will be timely investigated. If an investigation reveals a backflow incident, corrective actions will be taken immediately. b. Corrective Action Following detection of an incident, corrective actions taken may include: • Isolation Of The Contaminated Area; • Public Notification; • Flushing and Cleaning the System; and/or; • Pipeline Replacement. c. Isolation of the Contaminated Area If preventive measures fail and a backflow contamination event occurs, the Town will respond first by trying to limit the damage and remove the contaminant from the system. When a system learns of a contamination event, it will isolate the portion of the system that was contaminated to prevent the contamination from spreading. This is achieved by shutting off valves surrounding the contaminated area. Crews generally start at the point where the contamination was reported and work their way out until they find the edge of the contamination. d. Regulatory and Public Notification If a contamination event has occurred and the contamination was unable to be isolated before reaching consumers, the Florida Department of Environmental Protection (or approved county Health Department) will be notified by telephone. The Town will speak directly to or leave a voice mail message with the appropriate FDEP District Office or approved county health department as soon as possible, but no later than noon of the next business day. Additionally, per Chapter 62-555.350(10)(e) F.A.C., the Town must describe the incident in its operating reports. All consumers served by the system must be notified. The type of notification depends on the contaminant and the size of the area contaminated. If the contaminant has acute health effects notification must be as quick as possible, either through broadcast media or through system employees or public safety officials going door-to-door depending on the size of the area. For contaminants without immediate or short-term health effects, the public can be notified by other methods such as letters placed in mail boxes or local newspaper. Notification of the public can prevent health effects by minimizing possible contact with contaminated water until other immediate corrective measures have been completed. e. System Flushing and Cleaning Once a contamination event has been detected and isolated, Town personnel will flush the system as a first attempt to remove the contaminant. Flushing is done by opening up hydrants Cross Connection Control Program Page 9 of 10 Town of Gulf Stream October 2018 and expelling water from the system using a wide open valve approach until the contaminant can no longer be detected. If a large area has been affected several hydrants may need to be opened in succession to clean the system. Flushing generally moves from the source of contamination in the downstream direction. Some contaminants may not be adequately removed by flushing. Microbial contaminants may concentrate in biofilms that may not be easily dislodged by flushing alone. Other contaminants may adsorb to biofilm layers or corroded pipe materials and be released slowly to water in the pipe and, therefore, may take an unreasonable amount of time to flush from the system. In these cases, the Town may opt to physically clean the pipelines. Pigging and rodding are cleaning methods where a device is introduced into the pipe that physically scrapes biofilm and corrosion layers from the sides of the pipe. Jetting and sandblasting can also be used to remove such layers. Typically pipes are disinfected and flushed after a physical cleaning by one of the above methods. L Pipeline Replacement Some contaminants may not be removed by physical cleaning. Examples include pesticides which can be adsorbed by cleaned pipe material and then slowly released back into solution by the introduction of fresh water. Other contaminants such as highly corrosive or explosive contaminants may cause damage to the system. In these cases, the Town may choose to replace the contaminated piping and other appurtenances.
