(A) When cross connections are found to exist, the owner, his or her agent, occupant, or tenant will be notified in writing to disconnect the cross connection within the time limit established by the Public Works Director. 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 as follows:
(1) Cross connection with private wells or other auxiliary water supplies -immediate disconnection.
(2) 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.
(3) All industrial and non-residential 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 unless otherwise approved by the Public Works Director or his or her authorized designee.
(4) If, in the judgment of the Public Works Director, an imminent health hazard exists, water service to the building or premises where a cross connection exits may be terminated unless an air gap is immediately provided, or the cross connection is immediately eliminated.
(5) All lawn irrigation systems must have a double check valve assembly as a minimum containment facility.
(6) Based upon recommendation from the Public Works Director, the consumer is responsible for installing sufficient internal isolation backflow prevention assemblies and/or methods (such as air gap, pressure vacuum breakers, reduced pressure principle backflow prevention assembly, double check vale assembly).
(7) Water mains served by the town but not maintained by the town should be considered cross connections, with degree of hazard to be determined by the Public Works Director. Degree of protection shall be based upon the degree of hazard, as determined by the Public Works Director.
(8) In the event that a town cross connection control inspector does not have sufficient access to every portion of a private water system (such as classified research and development facilities; federal government property) to allow a complete evaluation of the degree of hazard associated with such private water systems, an approved reduced pressure principle assembly shall be required as a minimum of protection.
(9) Customers shall not modify their private water system in a manner that would affect the degree of hazard of such system until the town has been provided with information showing that the appropriate backflow prevention assembly is installed. If such modification or change is determined by the Public Works Director to require the installation of a different backflow prevention assembly, the required backflow prevention assembly must be installed in accordance with provision of this subchapter prior to making the proposed modification or change.
(B) 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.
