2060-AU38 202004 Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Office of Air and Radiation OAR 2000 Environmental Protection Agency EPA Extension of Photochemical Assessment Monitoring Stations Compliance Deadline

Significant revisions to the Photochemical Assessment Monitoring Stations (PAMS) requirements were made as part of the 2015 Ozone National Ambient Air Quality Standards review. The revised PAMS requirements significantly reduced the number of PAMS sites (from 75 to 43) while improving spatial coverage. States were required to start making PAMS measurements by the compliance deadline of June 1, 2019. The EPA has extended the compliance date for the required PAMS by two years, from June 1, 2019 to June 1, 2021 to allow states more time to purchase and become proficient with the necessary equipment.
