(ix) Removal of Backflow Prevention Assemblies a. Approval must be obtained from the Administrative Authority before a backflow prevention assembly for containment is removed,relocated,or replaced. b. The use of an assembly may be discontinued and the assembly removed from service upon presentation of sufficient evidence that the customer qualifies for an exemption. C. An assemblymaybe relocated following confmnationby the Administrative Authority that the relocation will continue to provide the required protection and satisfy installation requirements.A test will be required following the relocation of the assembly. d. An assembly may be removed and replaced, provided the water use is discontinued until the replacement assembly is installed. e. An assembly may be removed to protect it from freezing provided that: 1. water use is discontinued until the assembly is reinstalled and tested;and 2. the Administrative Authority is notified in writing within five days of the removal.

Backflow prevention assemblies for containment which are in place,but have been out of service for more than three months, shall be tested before being put back into operation. Backflow prevention assemblies for containment used in seasonal applications shall be tested before being put into operation each season. d. Before being placed back into service,any backflow prevention assembly for containment which fails a test shall be repaired or replaced.

(xii) Backflow Incidents a. The customer shall immediatelynotifythe Administrative Authority when the customer becomes aware that Backflow has occurred in the building,property,or private water systemreceiving water service. b. The Administrative Authority may order that water service be temporarily shut off when backflow occurs in a customer's building,property,or private water system.Such shut off is to protect the system from further contamination or pollution and to allow time for locating and mitigating the cause and extent of the contamination or pollution. (xiii) Existing Backflow Prevention Assemblies For Containment a. All backflow prevention assemblies for containment installed prior to November 1, 1996,that do not meet the requirements of these regulations but were approved testable assemblies for the purpose described herein at the time of installation and that have been properly installed and maintained,shall,except for the testing, inspection, and maintenance requirements under Section (x) and Section(xi), be excluded from the requirements of these rules so long as the Administrative Authority is assured that they will satisfactorily protect the PWS. Whenever the existing assembly for containment is moved from the present location,requires replacement,or when the use of the service area protected by the assembly changes so that the Administrative Authority determines that the customer no longer qualifies for a partial exemption,the unit shall be replaced by an approved backflow prevention assembly for containment meeting the requirements of these regulations. (xiv) Customer Non-compliance 20 a. In case of non-compliance with these regulations, the Administrative Authority shall notify the customer to comply within ten working days. In the event of failure or upon refusal of the customer to comply as ordered,the Administrative Authority may,after notice and reasonable opportunity for hearing, terminate water service.Non-compliance includes,but is not limited to,the following: 1.
