(2) Promote the elimination or control of existing cross-connections, actual or potential, between the public or consumer’s potable water system and nonpotable water systems, plumbing fixtures and sources or systems containing substances of unknown or questionable safety; and
(3) Provide for the maintenance of a continuing program of cross-connection control which will prevent the contamination or pollution of the public and consumer’s potable water systems.
(B) This subchapter has been developed in accordance with and as required under the following state requirements:
(1) The Illinois State Plumbing Code, 77 Ill. Adm. Code 890.1510, which requires protection of the potable water system from contamination due to backflow or backsiphonage of contaminants through the water service connection; and
