The board authorizes the department:

(1) To review new innovations, and if accepted for use, prepare appropriate amendments to chapter 246-262 WAC.

(2) To allow substitution of equipment, facilities, or procedures required by chapter 246-262 WAC when, in the sole discretion of the department, data and/or research provide sufficient evidence that such substitution is equivalent to the requirement and will adequately provide for the protection of the public health and safety of persons using the RWCF.
