HomeMy WebLinkAbout09.f EDB Response to Hathaway BF Compliance.2231 Foxwood EXECUTIVE SUMMARY AGENDA ITEM: Recommendation to uphold the policies and procedures of the Cross-Connection Control Policy (CCCP) as adopted by the Authority for the subject property: 2231 Foxwood Drive (Hathaway) Date: June 8, 2025 BACKGROUND: CCUA maintains a CCCP to protect the water system from potential cross-contamination sources on private property.Examples of contamination risk absent an appropriate cross-connection device are cross connections from a pressurized source or back-siphonage of non-potable quality water from a private source into the public system. At the 06/03/2025 Board of Supervisors meeting, Mr. Hathaway addressed the Board with concerns regarding CCUA's requirement to install a reduced-pressure (RP) backflow prevention assembly above ground at his property. This requirement was triggered upon CCUA's notification from the Clay County Department of Health of a permit issued for constructing a landscape irrigation well. Mr. Hathaway preferred installing a double check (DC) valve assembly below ground instead of an above-ground RP. He is concerned that the above-ground RP backflow assembly creates a potential hazard to lawnmowers or vehicular traffic.He has requested that he be permitted to install a below-ground double check (DC) valve assembly, which he feels presents less physical risk. However, according to CCUA's adopted CCCP, an RP assembly is required for all properties with real or potential high-hazard cross-connection risk. Wells and other sources of pressurized water on private property are considered high risk in the cross-connection control program because large volumes of untested water can be pushed into the public supply quickly. Private wells can sometimes be contaminated and are typically unmonitored. CCUA's CCCP, first adopted in 1995 and periodically amended to reflect current State regulations and best practices, clearly outlines that reduced-pressure assemblies must be installed for properties with real or potential high-risk cross-connections, including those with private wells. A DC is not approved for high-risk scenarios as it does not provide the same level of backflow prevention against backpressure or back-siphonage when a cross-connection is made. Over the past several years, staff have worked with the Clay County Health Department for consistent messaging regarding private well permits;nevertheless,we see the property owners say the well drillers did not advise them, and installation of a backflow device was not included as part of their installation. CCUA is frequently notified of the well only after the permit has been issued, and essential information regarding the CCCP and backflow protection is not always relayed to the property owner promptly when considering a well installation. To mitigate this issue staff is preparing a notification letter to all local well drilling companies informing them of CCUA's CCCP. The letter will request their cooperation in providing advance notice to property owners about the requirement to install a reduced-pressure backflow assembly when a well is planned or permitted. RECOMMENDATION: Staff respectfully recommend that the Board uphold the requirements of CCUA's CCCP. Upholding the CCCP is critical to protecting the integrity of the public water supply. While staff acknowledge Mr. Hathaway's concerns and the current communication gap, if a well drilling company does not advise or install the backflow preventer concurrent with the well installation, substituting the required RP with a DC would reduce the level of protection against a real or potential cross connection. To support better understanding and compliance, staff will: • Continue working with the Clay County Health Department and Well Drillers to improve communication with property owners so that the owners fully understand CCUA's CCCP backflow requirements. • Continue working directly with Mr. Hathaway to determine a mutually agreed-upon location for the RP assembly that mitigates the risk of lawnmower damage and vehicular traffic while ensuring the installation meets all technical and safety standards.

Legal Authority Clay County Utility Authority's (CCUA) Resolution No. 2019/2020-01 states, 'All Customers shall comply with Utility's Cross-Connection Control Policy, as previously adopted by the Board of Supervisors for Utility on April 14, 1995, and as amended, restated, and readopted on April 4, 2000, as the same may be amended and then in force. A copy of that policy is on file with the Recording Secretary for the Authority and is available for inspection during normal business hours of the Authority. This plan serves to capture the components of CCUA's Cross-Connection Control Policy that address the requirements of Table 62-555.360-1, Florida Administrative Code (F.A.C.), referenced in Rule 62-555.360, F.A.C., Cross-Connection Control for Public Water Systems. Section II. Policy Establishing Where Backflow Protection at or for Service Connections from CCUA is Mandatory CCUA's Cross-Connection Control Policy establishes where backflow protection at or for service connections from CCUA is mandatory. This policy is no less stringent than Table 62-555.360-2 and requires all non-residential customers to install and maintain a reduced-pressure principle assembly(RP). CCUA requires an RP at all non-residential service customers due to the possibility of tenant changes and change in use over time.

A DC may be provided if both of the following conditions are met: • The dedicated irrigation service connection initially was constructed before 5-5-14. • No chemicals are fed into the irrigation system. 5 The CWS may rely on the internal backflow protection required under the Florida Building Code or the predecessor State plumbing code. The CWS may,but is not required to, ensure that such internal backflow protection is inspected/tested and maintained the same as backflow protection provided at or for service connections from the CWS. 6 The Department shall allow an exception to the requirement for backflow protection at or for a residential or non-residential dedicated fire service connection from a CWS to a wet-pipe sprinkler,or wet standpipe,fire protection system if both of the following conditions are met: • The fire protection system was installed and last altered before 5-5-14. • The fire protection system contains no chemical additives and is not connected to an auxiliary water system as defined in Footnote 4. Upon discovery of any cross-connection between the fire protection system and any reclaimed water system on the customer's premises,the CWS shall ensure that the cross-connection is eliminated. s The CWS shall ensure that backflow protection commensurate with the degree of hazard is provided at or for the service connection from its fire hydrant. 3 Section III. Policy Regarding Ownership, Installation, Inspection/Testing, and Maintenance of Required Backflow Protection Responsibility for Installation, Inspection/Testing, and Maintenance of Required Backflow Protection CCUA owns and is responsible for the installation and replacement of any residential dual check valve device at the discharge side of the meter. The customer owns, and is responsible for, the installation, inspection/testing, and maintenance of testable backflow prevention assemblies at the discharge side of the meter and anywhere on the customer's potable water system. Design and Performance Standards for New Backflow Protection All approved testable backflow prevention assemblies that are recognized by CCUA shall comply with the standards set forth by one or more of the following agencies: • State of Florida Department of Environmental Protection • American Water Works Association • American Society of Sanitary Engineers • University of Southern California Foundation for Cross-Connection Control and Hydraulic Research • Southern Building Code Congress International Installation Criteria for New Backflow Protection All installations shall be consistent with installation criteria in AWWA Manual M14 as incorporated into subsection 62-555.360(2), F.A.C., and shall assure the backflow protection is installed as close as practical to CCUA's meter or customer's property line but,in all cases,before the first distribution line off the customer's water service line. CCUA's engineering, Backflow & Greasetrap Administrator, and/or certified distribution and collection staff shall designate the installation location, adequacy of structural support, and height above natural flood grade of an approved backflow prevention assembly. Air Gap Inspections and Qualifications for Persons Inspecting Required Air Gaps Customers that utilize auxiliary water supply while connected to CCUA's potable water will be required to maintain an air-gap separation on that auxiliary water supply source. Air gaps will be the customers sole responsibility to maintain and a certified CCUA technician will approve upon connection to city water or new service set up. CCUA does not conduct, or require customers to conduct, air gap inspections since a reduced-pressure principle assembly is also required for all customers that utilize auxiliary water supplies. If future needs require the use of an air gap as the sole means of backflow prevention, CCUA will amend the Cross Connection Control Policy to specify the frequency for inspection and shall specify qualifications for person inspecting such air gaps. Per DEP, all air gaps being required at or for service connections shall be inspected at least annually. 4 Frequency for Testing Required Backflow Preventer Assemblies" All testable assemblies located at the service connections shall be tested after installation or repair and at least annually thereafter. All assemblies that fail to meet performance standards shall be repaired immediately. Qualifications for Persons Inspecting Required Assemblies" Only persons who are certified in backflow prevention assembly testing and repair may conduct backflow assembly inspections, tests and perform repairs. All persons who conduct tests and perform repairs must be registered with CCUA. To register with CCUA,the following information is required: • Successful completion of a backflow assembly tester and repair certification program endorsed by the Florida Section of the American Water Works Association; • A certificate of competency executed by authorized representatives of the issuing educational institution and by authorized representatives of the Florida Section of the American Water Works Association; • Name, address, and phone number of the business conducting backflow prevention assembly test(s); • Laboratory certification of all test gauges used to complete backflow assembly tests; • All registered businesses shall provide documentation that names CCUA as an additional insured on their comprehensive general liability insurance policy.Minimum coverage shall be $500,000 per occurrence, $1,000,000 aggregate. CCUA will not accept backflow assembly prevention test reports unless a properly registered tester performs the test. Test Procedures for Required Assemblies" Before each field test the verified tester shall take the following steps: 1. Notify the owner and user of the backflow assembly that the water service will be shut off during the test. If a fire system will be affected, the Executive Director and the Fire Chief shall also be notified. 2. Verify that the proper assembly is being tested by checking the identification tag and meter number. 3. Inspect the assembly for minimum clearances and properly located shut off valves and test cocks. 4. Observe the assembly and surroundings for signs of leakage, vandalism, or alterations. After each field test the certified tester shall take the following steps: 1. Tag the assembly with a weather-proof tag that contains the following information: company name that performed the test, company phone number, and month/year test passed. The tag shall be affixed to the assembly in such a manner that it will remain in place until removed at the next test. 2. Mail or email test report to CCUA within ten(10)days after initial test. 5 Test Requirements for Reduced Pressure Principle Assemblies Test 1: The operation of the pressure differential relief valve shall maintain a zone between the two check valves at least 2 psi less than the supply pressure. Test 2: The number 2 shut-off valve shall close fully and be leak tight against back pressure and back-siphonage. Test 3: The number 2 check valve shall maintain static pressure drop across the check valve of at least 1 psi in the direction of flow. The check valve shall permit no leakage in a direction reverse to the normal flow. Test 4: The number 1 check valve shall maintain a static pressure drop across the check valve of 3.0 psi or greater than the recorded opening point of the relief valve. The check valve shall permit no leakage in a direction reverse to the normal flow. Test Requirements for Double Check Valve Assemblies Test 1: The number 1 and number 2 shut off valves shall close fully and be leak tight. Test 2: The number 1 check valve shall maintain a static pressure drop across the check valve at least 1 psi in the direction of flow. The check valve shall permit no leakage in a direction reverse to the normal flow. Test 3: The number 2 check valve shall maintain a static pressure drop across the check valve of at least 1 psi in the direction of flow. The check valve shall permit no leakage in a direction reverse to the normal flow. Testing double check valve assemblies with limited access or below grade installations may require the downstream reference point being raised with a sight tube to an elevation level with the test gauge. 11Including Double Check Valve Assemblies (DCs) and Double Check Detector Assemblies (DCDAs); Pressure Vacuum Breaker Assemblies (PVBs); and Reduced-Pressure Principle Assemblies (RPs) and Reduced-Pressure Principle Detector Assemblies(RPDAs) Frequency for Refurbishing or Replacing Required Dual Check Devices (DuCs) CCUA is developing a plan to replace all dual check devices at least once every nine years. The replacement schedule is dependent upon a rate study that is currently underway and will be completed by August 2022. CCUA anticipates the plan will consist of replacing approximately 32,000 existing dual check valves at a rate of 20%per year so that all dual check valves installed in 2013 or earlier will be replaced no later than 2028. The plan is expected to allow for replacement of dual check valves installed in 2014 or later at least once every 9 years. Section IV. Evaluating Customers' Premises to Establish the Category of Customer and the Required Backflow Protection Newly Constructed Service Connections CCUA evaluates newly constructed service connections before supplying water to the service connection to determine the category of customer and the backflow protection required. All construction plans for proposed new facilities are made available to CCUA and reviewed by CCUA's engineering and/or service availability departments to determine the degree of possible cross-connection hazards. At that time,backflow prevention requirements in accordance with this 6 CCCP are initiated. Existing Service Connections CCUA evaluates existing(i.e.,previously constructed)service connections whenever the customer connects to a reclaimed water distribution system, whenever an auxiliary water system is discovered on the customer's premises, whenever a prohibited or inappropriately protected cross- connection is discovered on the customer's premises, and whenever the customer's premises is altered under a building permit in a manner that could change the backflow protection required at or for a service connection to the customer. CCUA will conduct a cross-connection inspection each time an application is received in new or existing service areas that are providing reclaimed water to residential and/or commercial customers. A satisfactory cross connection inspection is required every time there is a 'turn on' of service requested at an address. An inspection is also required after all modifications to any reclaimed irrigation system. All residential sites receiving reclaimed water must have a residential backflow prevention device on the incoming potable water supply line. Section V. CCCP Records Current Inventory of Required Backflow Protection CCUA maintains a current inventory of backflow protection required at or for service connections from CCUA. CCUA's FileMaker program electronically tracks the number and type of backflow protection devices installed throughout CCUA's distribution system. CCUA's Inventory Manager tracks number and type of backflow prevention devices in CCUA's maintenance building ready for use using Excel spreadsheets on a common drive. Records of the Installation,Inspection/Testing, and Repair of Required Backflow Protection CCUA maintains records of the installation, inspection/testing, and repair of required backflow protection electronically using CCUA's FileMaker program and all paper reports are scanned into Laserfiche for electronic records keeping. Records are maintained for a period of not less than ten (10)years. Testers not employed by CCUA must submit a completed report on an approved CCUA testing form. Reports should be submitted via email, mail, or fax to the Backflow & Greasetrap Administrator within ten (10) days of testing. 7 62-555.360 Cross-Connection Control for Public Water Systems. (1)Cross-connections, as defined in Rule 62-550.200,F.A.C.,are prohibited unless appropriate backflow protection is provided to prevent backflow through the cross-connection into the public water system. This does not prohibit a public water system from being interconnected to another public water system of the same type without backflow protection(i.e., a community water system [CWS] may be interconnected to another CWS without backflow protection, a non-transient non-community water system [NTNCWS] may be interconnected to another NTNCWS without backflow protection, and a transient non-community water system [TWS]may be interconnected to another TWS without backflow protection). (a) Appropriate backflow protection for various applications is described in Recommended Practice for Backflow Prevention and Cross-Connection Control. AWWA Manual M14,Third Edition,as clarified and modified in paragraphs(b)and(c)below and in Table 62-555.360-2, which appears at the end of this section. The third edition of AWWA Manual M14 is incorporated herein by reference; is available from the American Water Works Association, 6666 West Quincy Avenue, Denver, CO 80235, www.awwa.org; and is available for review at the Department of Environmental Protection, Source and Drinking Water Program, MS 3520, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400, at the Department of Environmental Protection district offices, and at the Approved County Health Departments. (b) Except for the temporary cross-connections described in paragraph (c) below, cross-connections between a public water system and a wastewater system or reclaimed water system are prohibited (i.e., an air gap shall be maintained between any public water system and any wastewater system or reclaimed water system).The Department shall allow an exception to this requirement if the supplier of water provides justification for the exception and provides alternative backflow protection that achieves a level of reliability and public health protection similar to that achieved by an air gap (e.g.,two biannually-tested reduced-pressure principle assemblies installed in series); however, in no case shall the Department allow a single, annually-tested mechanical backflow preventer to be used as the only protection against backflow of wastewater or reclaimed water into a public water system. (c) Temporary cross-connections may be made between a public water system and a wastewater system or reclaimed water system for either of the following purposes: 1. To supply water for flushing or testing a new wastewater force main or new reclaimed water main, in which case a double check valve assembly or reduced-pressure principle assembly shall be provided at the cross-connection. 2. To supply water for temporarily operating a new reclaimed water main that has not yet been connected to a reclaimed water supply,in which case a reduced-pressure principle assembly shall be provided at the cross-connection. (2)Each community water system(CWS) shall establish and implement a cross-connection control program utilizing backflow protection at or for service connections from the CWS in order to protect the CWS from contamination caused by cross-connections on customers' premises. This program shall include a written plan that is developed using recommended practices of the American Water Works Association set forth in Recommended Practice for Backflow Prevention and Cross-Connection Control: AWWA Manual M14, Third Edition, as clarified and modified in paragraph (a) below. The third edition of AWWA Manual M14 is incorporated herein by reference and is available as indicated in paragraph 62-555.360(1)(a),F.A.C. (a) The minimum components that each CWS shall include in its written cross-connection control plan are listed and described in Table 62-555.360-1, which appears at the end of this section. The categories of customers for which each CWS shall ensure backflow protection is provided at or for the service connection from the CWS to the customer are listed in Table 62-555.360-2, which appears at the end of this section. (b)Each CWS serving more than 10,000 persons shall prepare and submit cross-connection control program annual reports. The first annual report shall cover calendar year 2016, and subsequent annual reports shall cover each calendar year thereafter. These reports shall be prepared using Form 62-555.900(13),Cross-Connection Control Program Annual Report,effective 5-5-14,which is incorporated herein by reference and which is available as described in Rule 62-555.900, F.A.C., and at http://www.flrules.org/Gateway/reference.asp?No=Ref-04104. These reports shall be submitted to the appropriate Department of Environmental Protection district office or Approved County Health Department within three months after the end of the calendar year covered by the report. (3)Upon discovery of a prohibited or inappropriately protected cross-connection, public water systems either shall ensure that the cross-connection is eliminated, shall ensure that appropriate backflow protection is installed to prevent backflow into the public water system,or shall discontinue water service. If the discovered cross-connection is on the premises of a customer of a community water system (CWS) and if the customer's premises is in a category described in Table 62-555.360-2, which appears at the end of this section, the CWS shall ensure that appropriate backflow protection is provided at or for the water service connection to the customer regardless of whether the cross-connection is eliminated or whether internal backflow protection is installed at the cross- connection to the customer's plumbing system. Table 62-555.360-1: Minimum Components that Each Community Water System(CWS)Shall Include in Its Written Cross- Connection Control(CCC)Plan(Effective 5-5-14) Component Number and Description I. Legal authority for the CWS's CCC program — i.e., an ordinance, a bylaw or resolution, or water service rules and regulations. The legal authority shall include or reference Components 2 and 3 below. II.The CWS's policy establishing where backflow protection at or for service connections from the CWS is mandatory. A. This policy shall identify categories of customers for which the CWS is requiring backflow protection at or for the service connection to the customer and shall specify the minimum backflow protection that the CWS is requiring for each such category of customers. B.This policy shall be no less stringent than Table 62-555.360-2,which appears at the end of Rule 62-555.360,F.A.C. III. The CWS's policy regarding ownership, installation, inspection/testing, and maintenance of backflow protection that the CWS is requiring at or for service connections from the CWS. A. This policy shall specify whether the CWS or customer is responsible for installation,inspection/testing,and maintenance of backflow protection being required at or for service connections. B. This policy shall specify design and performance standards, and shall specify installation criteria, for new backflow protection being required at or for service connections. Installation criteria shall be consistent with installation criteria in AWWA Manual M14 as incorporated into subsection 62-555.360(2),F.A.C., and shall assure the backflow protection is installed as close as practical to the CWS's meter or customer's property line but, in all cases, before the first distribution line off of the customer's water service line. C. This policy shall specify the frequency for inspecting air gaps (AGs)being required at or for service connections and shall specify qualifications for persons inspecting such AGs. All AGs being required at or for service connections pursuant to Table 62- 555.360-2,which appears at the end of Rule 62-555.360,F.A.C.,shall be inspected at least annually. D.

E. This policy shall specify the frequency for refurbishing or replacing dual check devices (DuCs) being required at or for service connections. DuCs being required at or for service connections pursuant to Table 62-555.360-2,which appears at the end of Rule 62-555.360, F.A.C., shall be refurbished or replaced at least once every 5 to 10 years or at a lesser frequency determined by the CWS if the CWS documents that the lesser frequency is appropriate based on data from spot-testing DuCs in its system or based on data from backflow sensing meters in its system. IV. The CWS's procedures for evaluating customers' premises to establish the category of customer and the backflow protection being required at or for the service connection(s)from the CWS to the customer.3 A. The CWS shall evaluate the customer's premises at a newly constructed service connection before the CWS begins supplying water to the service connection. B. The CWS shall evaluate the customer's premises at an existing—i.e.,previously constructed—service connection whenever the customer connects to a reclaimed water distribution system,whenever an auxiliary water system is discovered on the customer's premises, whenever a prohibited or inappropriately protected cross-connection is discovered on the customer's premises, and whenever the customer's premises is altered under a building permit in a manner that could change the backflow protection required at or for a service connection to the customer. Component Number and Description V. The CWS's procedures for maintaining CCC program records.4 A. The CWS shall maintain a current inventory of backflow protection being required at or for service connections from the CWS. B. The CWS shall maintain records of the installation,inspection/testing,and repair of backflow protection being required at or for service connections from the CWS. 1 Backflow preventer assemblies include the following: double check valve assemblies (DCs) and double check detector assemblies (DCDAs); pressure vacuum breaker assemblies (PVBs); and reduced-pressure principle assemblies (RPs) and reduced- pressure principle detector assemblies(RPDAs). 2 For the purpose of this table,"residential service connection"means any service connection,including any dedicated irrigation or fire service connection, that is two inches or less in diameter and that supplies water to a building, or premises, containing only dwelling units;and"non-residential service connection"means any other service connection. 3 CWSs may evaluate customers' premises using questionnaires, reviews of construction plans or pertinent records, on-site inspections,or any combination thereof. 4 CWSs may maintain all records in either electronic or paper format.

A PVB may not be used if backpressure could develop in the downstream piping. 2 The CWS shall determine the degree of hazard."Low hazard"or"non-health hazard"and"high hazard"or"health hazard"are defined in AWWA Manual M14 as incorporated in paragraph 62-555.360(1)(a),F.A.C.,and subsection 62-555.360(2),F.A.C. 3 A DC may be provided if it was installed before 5-5-14; and if such a DC is replaced on or after 5-5-14, it may be replaced with another DC. 4 For the purpose of this table,"auxiliary water system"means a pressurized system of piping and appurtenances using auxiliary water, which is water other than the potable water being supplied by the CWS and which includes water from any natural source such as a well, pond, lake, spring, stream, river, etc., includes reclaimed water, and includes other used water or industrial fluids described in AWWA Manual M14 as incorporated in paragraph 62-555.360(1)(a), F.A.C., and subsection 62-555.360(2), F.A.C.; however, "auxiliary water system" specifically excludes any water recirculation or treatment system for a swimming pool, hot tub, or spa. (Note that reclaimed water is a specific type of auxiliary water and a reclaimed water system is a specific type of auxiliary water system.) 5 The Department shall allow an exception to the requirement for backflow protection at or for a residential or non-residential service connection from a CWS to premises where there is an auxiliary or reclaimed water system if all of the following conditions are met: ❑ The CWS is distributing water only to land owned by the owner of the CWS. ❑ The owner of the CWS is also the owner of the entire auxiliary or reclaimed water system up to the points of auxiliary or reclaimed water use. ❑ The CWS conducts at least biennial inspections of the CWS and the entire auxiliary or reclaimed water system to detect and eliminate any cross-connections between the two systems. 6 For the purpose of this table,"residential service connection"means any service connection,including any dedicated irrigation or fire service connection, that is two inches or less in diameter and that supplies water to a building, or premises, containing only dwelling units;and"non-residential service connection"means any other service connection. 7 A DuC may be provided only if there is no known cross-connection between the plumbing system and the auxiliary or reclaimed water system on the customer's premises. Upon discovery of any cross-connection between the plumbing system and any reclaimed water system on the customer's premises, the CWS shall ensure that the cross-connection is eliminated. Upon discovery of any cross-connection between the plumbing system and any auxiliary water system other than a reclaimed water system on the customer's premises, the CWS shall ensure that the cross-connection is eliminated or shall ensure that the backflow protection provided at or for the service connection is equal to that required at or for a non-residential service connection. 8 Reclaimed water regulated under Part III of Chapter 62-610,F.A.C., is a low hazard unless it is stored with surface water in a pond that is part of a stormwater management system,in which case it is a high hazard;well water is a low hazard unless determined otherwise by the CWS; industrial fluids and used water other than reclaimed water are high hazards unless determined otherwise by the CWS;reclaimed water not regulated under Part III of Chapter 62-610,F.A.C.,and surface water are high hazards. 9 Upon discovery of any cross-connection between the plumbing system and any reclaimed water system on the customer's premises,the CWS shall ensure that the cross-connection is eliminated. 10 A DC may be provided if both of the following conditions are met: ❑ The dedicated irrigation service connection initially was constructed before 5-5-14. ❑ No chemicals are fed into the irrigation system. 11 The CWS may rely on the internal backflow protection required under the Florida Building Code or the predecessor State plumbing code. The CWS may, but is not required to, ensure that such internal backflow protection is inspected/tested and maintained the same as backflow protection provided at or for service connections from the CWS. 12 The Department shall allow an exception to the requirement for backflow protection at or for a residential or non-residential dedicated fire service connection from a CWS to a wet-pipe sprinkler, or wet standpipe, fire protection system if both of the following conditions are met: ❑ The fire protection system was installed and last altered before 5-5-14. ❑ The fire protection system contains no chemical additives and is not connected to an auxiliary water system as defined in Footnote 4. 13 Upon discovery of any cross-connection between the fire protection system and any reclaimed water system on the customer's premises,the CWS shall ensure that the cross-connection is eliminated. 14 The CWS shall ensure that backflow protection commensurate with the degree of hazard is provided at or for the service connection from its fire hydrant.
