(1) The board shall establish criteria for determining if any waste or combination of wastes is hazardous or nonhazardous, for the purposes of this chapter.
(2) The board may adopt, and amend from time to time a list or lists of hazardous wastes. The board may, with public notice but without the necessity of a public hearing, list as hazardous any waste or combination of wastes determined to be hazardous by the United States environmental protection agency. To accomplish this goal, the board may adopt by reference the regulations containing the lists of hazardous wastes and the set of characteristics for identifying hazardous wastes promulgated by the United States environmental protection agency pursuant to RCRA. The board shall update the regulations adopted pursuant to this section as needed to reflect regulatory amendments promulgated by the United States environmental protection agency. The board may adopt regulations for a state hazardous waste delisting program equivalent to that set forth in 40 CFR sections 260.20(b) and 260.22. The state delisting program shall provide for public notice and opportunity for comment before granting or denying delisting requests.
