Colorado's Air Quality Control Commission (AQCC) is the governing body "appointed by the governor and authorized by the Colorado General Assembly to oversee Colorado’s air quality program"¹ and responsible for implementing policy. Four state bills from the 2019 legislative session² require the AQCC to promulgate additional emission control regulations.
The most recent AQCC meeting was held in Lamar, CO on June 20, 2019. According to Garry Kaufman of the CDPHE-APCD, there are three immediate (within one year) priorities for rulemaking that originate from this legislature. The three AQCC rulemakings that have been scheduled (which are separate from the forthcoming COGCC rulemakings) are below with associated approximate rulemaking hearing dates. The fourth rulemaking below is estimated from the AQCC long term calendar as of August 2019.
Altogether, these efforts will help with our next iteration of the ozone SIP. This could be finished by the second half of 2020, but there are differing opinions on that timeline.
One of the issues that we've been tracking closely is new regulation for continuous methane monitoring, as required by SB 19-181. As of now, it is expected to undergo rulemaking during the spring of 2020, but no firm schedule has been set.
