This Part sets forth the commission's rules implementing the Home Energy Fair Practices Act as it applies to residential customers of waterworks corporations with annual gross revenues in excess of $250,000 (L. 1986, ch. 176). That act establishes as State policy that the continued provision of water service to such residential customers without unreasonable qualifications or lengthy delays is necessary for the preservation of the health and general welfare and is in the public interest. Every right and duty under this Part imposes an obligation of good faith, honesty and fair dealing in its performance and enforcement. The provisions of this Part must be interpreted so as to fulfill its purpose and policy.
