(1) The purpose of this chapter is to implement the policy and intent of RCW 80.50.010. This chapter sets forth performance standards and mitigation requirements specific to seismicity, noise limits, fish and wildlife, wetlands, water quality, and air quality, associated with site certification for construction and operation of energy facilities under the jurisdiction of the council. The council shall apply these rules to site certification agreements issued in connection with applications filed after the effective date of this chapter. Except for the provisions in chapter 463-66 WAC, these regulations shall not apply to energy facilities for which site certification agreements have been issued before the effective date of this chapter.

(2) The provisions of this chapter shall apply to the construction and operation of energy facilities, pursuant to chapter 80.50 RCW.

(3) Compliance with the standards within this chapter shall satisfy, in their respective subject areas, the requirements for issuance of a site certificate for construction and operation of energy facilities specified in subsection (2) of this section provided, however, that the council may require additional mitigation in the event that documents prepared pursuant to 43.21 RCW (State Environmental Policy Act), demonstrate that the project poses a probable significant adverse impact that is not mitigated by the provisions of this chapter.
