N.M. Stat. § 74-9-32
Exemptions from the application of the provisions of the Solid Waste Act may be applied for and shall be issued by the board, either for a single applicant or a group of applicants having substantially identical grounds for the issuance of the exemption, if the board determines after a hearing that the applicant or group of applicants is subject to requirements or regulations under an applicable federal or state law that imposes as stringent or more stringent requirements for the applicant's or applicants' management of its solid waste than the provisions of the Solid Waste Act and regulations adopted under that act. Exemptions issued under this section shall be reviewed for renewal at time intervals determined by the board for each exemption, and the date for renewal shall be stated in the exemption.
