Sec. 69. (1) The director may promulgate, amend, and rescind rules pursuant to the administrative procedures act of 1969, 1969 PA 306, MCL 24.201 to 24.328, with respect to matters necessary for the administration of this act.

(2) Declaratory rulings that concern the application of occupational safety and health standards promulgated pursuant to this act to specific facts shall be made solely by the director or his or her authorized representative with respect to occupational safety standards or occupational health standards, pursuant to section 63 of the administrative procedures act of 1969, 1969 PA 306, MCL 24.263.

(3) Any occupational safety or health standard adopted by reference pursuant to section 14,  1 promulgated pursuant to this act, or continued in effect pursuant to sections 21(1) and 24(1)  2 is considered to supersede any occupational safety or health standard or rule promulgated pursuant to any other law of this state.
