Idaho Code § 39-4404
The legislature intends that the state of Idaho enact and carry out a hazardous waste program that will enable the state to assume primacy over hazardous waste control from the federal government.
The legislature finds that the RCRA, as amended, 42 U.S.C., section 6901 et seq., and federal regulations adopted pursuant thereto, establish complex and detailed provisions for regulation of those who generate, transport, treat, store, and dispose of hazardous wastes. The legislature cannot conveniently or advantageously set forth in this chapter all the requirements of all of the regulations which have been or will be established under RCRA. However, by the provisions of this chapter, the legislature desires to avoid the existence of duplicative, overlapping or conflicting state and federal regulatory systems.
Therefore, the board is directed to promulgate rules which are consistent with RCRA and the federal regulations adopted by the administrator of the United States environmental protection agency to implement RCRA. Farmers and ranchers who treat, store, or dispose of waste pesticides from their operations on lands owned or controlled by them shall not be required by board rules to do anything more than follow the instructions on the pesticide label and triple rinse empty containers in accordance with the RCRA regulations of the environmental protection agency. The board may not promulgate any rule that would impose conditions or requirements more stringent or broader in scope than RCRA and the RCRA regulations of the environmental protection agency. The board may, however, promulgate procedural rules and rules specifically authorized by this chapter or other state statutes without showing that those rules are required by RCRA or the regulations of the environmental protection agency; provided that those rules shall not conflict with this section, other sections of this chapter, RCRA, or the regulations of the environmental protection agency. Any rule promulgated by the board shall be valid until it is repealed or modified through the administrative process of chapter 52, title 67, Idaho Code.
