§ 50.420 ELIMINATION OF CROSS-CONNECTIONS; DEGREE OF HAZARD.
   When cross-connections are found to exist, the owner, his or her agent, occupant or tenant will be notified in writing to disconnect the same within the time limit established by the town's Public Utilities Department. The degree of protection required and maximum time allowed for compliance will be based upon the potential degree of hazard to the public water supply system. The maximum time limits are as follows:
   (A)   Cross-connections with private wells or other auxiliary water supplies: immediate disconnection;
   (B)   All facilities which pose a health hazard to the potable water system must have a containment assembly in the form of a reduced pressure principle backflow prevention assembly within 60 days;
   (C)   All industrial and commercial facilities not identified as a health hazard shall be considered non-health hazard facilities. All non-health hazard facilities must install, as a minimum containment assembly, a double check valve assembly within 90 days;
   (D)   If, in the judgment of the town's Public Utilities Department, an imminent health hazard exists, water service to the building or premises where a cross-connection exists may be terminated unless an air gap is immediately provided or the cross-connection is immediately eliminated;
   (E)   Based upon recommendation from the town, the consumer is responsible for installing sufficient internal isolation backflow prevention assemblies and/or methods (i.e., air gap, pressure vacuum breakers, reduced pressure principle backflow prevention assembly, double check valve assembly);
   (F)   Water mains served by Appalachian State University, but not maintained by the town, should be considered cross-connections, with degree of hazard to be determined by town's Public Utilities Department; the degree of protection shall be based upon the degree of hazard, as determined by the town's Public Utilities Department.
   (G)   In the event that a town Cross-Connection Control Inspector does not have sufficient access to every portion of a private water system (i.e., classified research and development facilities; federal government property) to allow a complete evaluation of the degree of hazard associated with the private water systems, an approved reduced pressure principle assembly shall be required as a minimum of protection.
   (H)   No person shall fill special-use tanks or tankers containing pesticides, fertilizers, other toxic chemicals or their residues from the public water system except at a location equipped with an air gap or an approved reduced pressure principle backflow prevention assembly properly installed on the public water supply.
