The requirements of this chapter, are based upon chapter 80.70 RCW and are separate and distinct from the requirements found in chapter 463-85 WAC - greenhouse gases performance standard that are based upon chapter 80.80 RCW. These two requirements are required to work in unison with each other in a serial manner. The first requirement is the emissions performance standard under chapters 80.80 RCW and 463-85 WAC. Once that standard is met, the requirements of chapters 80.70 RCW and 463-80 WAC are applied.
