(1) Notwithstanding any other provision of law, any legal requirement identified under RCW 43.21K.060(1) shall be superseded or replaced in accordance with the terms of the environmental excellence program agreement. Legal requirements contained in a permit that are affected by an environmental excellence program agreement will continue to be enforceable until such time as the permit is revised in accordance with subsection (2) of this section. With respect to any other legal requirements, the legal requirements contained in the environmental excellence program agreement are effective as provided by the environmental excellence program agreement, and the facility or facilities covered by an environmental excellence program agreement shall comply with the terms of the environmental excellence program agreement in lieu of the legal requirements that are superseded and replaced by the approved environmental excellence program agreement.

(2) Any permits affected by an environmental excellence program agreement shall be revised to conform to the environmental excellence program agreement by the agency with jurisdiction. The permit revisions will be completed within one hundred twenty days of the effective date of the agreement in accordance with otherwise applicable procedural requirements, including, where applicable, public notice and the opportunity for comment, and the opportunity for review and objection by federal agencies.

(3) Other than as superseded or replaced as provided in an approved environmental excellence program agreement, any existing permit requirements remain in effect and are enforceable.

(4) A programmatic environmental excellence program agreement shall become applicable to an individual facility when all directors entering into the programmatic agreement approve the owner or operator's commitment to comply with the agreement. A programmatic agreement may not take effect, however, until notice and an opportunity to comment for the individual facility has been provided in accordance with the requirements of RCW 43.21K.070 (1) through (3).
