Upcoming Changes to Stationary Source Regulations
EPA’s Fall 2023 regulatory agenda has been released. The following table summarizes EPA’s Office of Air and Radiation’s (OAR) plans for proposing and finalizing new regulations. Among other things, OAR is responsible for crafting regulations under the NSPS, NESHAP (including air toxics), and NSR programs. The table is not all-inclusive of every OAR regulatory action. Instead, it includes those actions McCoy and Associates believes to be of broad interest to the regulated community.
