N.M. Stat. § 59A-53-12
The marshal has authority to promulgate, modify, amend and revoke from time to time rules, including those for mutual aid among and between fire departments; provided that no such rules shall allow any fire department to extend its service in any manner that would jeopardize the fire insurance rates within its municipality or county fire district, as the marshal may determine, in the marshal's discretion, to be necessary, advisable or proper to accomplish the objectives of the Fire Protection Fund Law. Among other things, these rules shall include, but not be limited to, a list of firefighting equipment, apparatus and other items that may properly be purchased by a municipality or by any county fire district from funds distributed from the fire protection fund, and standards of quality, construction and performance to be met by major firefighting appliances, training requirements, firefighting protective clothing and equipment standards, and by fire stations and substations, proposed to be purchased or constructed by a municipality or district from money distributed from the fire protection fund. All rules shall be filed and published as required by law. Rules of this nature heretofore promulgated by the superintendent and now in effect shall continue in effect until hereafter revoked or modified. Nothing in this section shall be construed to grant regulatory authority over the Volunteer Firefighters Retirement Act to the marshal.
