Greenhouse Gas Emissions Performance Standard
Commerce recently completed a rulemaking to update the average greenhouse gas emission rate from new, commercially available combined cycle combustion turbines, referenced in RCW 80.80.040 Greenhouse gas emission performance standard – Rules. Commerce’s rule is referred to in Ecology rules that establish the state greenhouse gas emission performance standard for utility baseload electric generation, which is the lower of 1,100 pounds per megawatt-hour, or the average greenhouse gas emission rate as determined under RCW 80.80.050. The determination is to be updated every five years after July 22, 2007.
Commerce filed a draft rule and supplemental CR-102 on May 2 for publication on May 16. A public hearing on the proposed rule was held June 11, and written comments were accepted through June 14. Based on comments received, Commerce filed a revised version of the proposed rule and a second supplemental CR-102 on July 18 for publication on Aug. 1. A public hearing on the revised version of the proposed rule was held at Commerce’s Olympia Office, 1011 Plum St. SE, Olympia, WA, 98504 on Aug. 23 at 10 a.m. Commerce adopted the proposed rule, establishing the new average greenhouse gas emission rate as 925 lbs/mWh, on Sept. 19, 2018.
