This chapter is promulgated under the authority of chapter 90.76 RCW and establishes a statewide underground storage tank program that is intended, at a minimum, to meet the legislature's intent to:

(1) Address the serious threat to human health and the environment posed by leaking underground storage tanks containing petroleum and other regulated substances;

(2) Meet the requirements for delegation of the federal underground storage tank program of the Resource Conservation and Recovery Act of 1976, as amended (42 U.S.C. Sec. 6901 et seq.);

(3) Be consistent with and no less stringent than the requirements in the federal regulations and the Underground Storage Tank Compliance Act of 2005 (42 U.S.C. Sec. 15801 et seq., Energy Policy Act of 2005, P.L. 109-58, Title XV, Subtitle B); and

(4) Allow for the establishment of local requirements more stringent than the statewide requirements to protect environmentally sensitive areas.
