Draft 2019 Air Monitoring Network Plan and 2018 Air Monitoring Network Plan

July 22, 2019

Each year, MassDEP is required to submit an Ambient Air Monitoring Network Plan to the U.S. Environmental Protection Agency (EPA) for review and approval.  MassDEP operates a network of 21 ambient air monitoring stations in 17 communities located across the Commonwealth. The Network Plan reviews the air monitoring network to ensure that it meets EPA’s monitoring requirements, describes which pollutants and other parameters MassDEP measures, and describes recent and planned changes to the monitoring network.  MassDEP is holding a 30-day public comment period on the Draft 2019 Network Plan.  MassDEP also has posted the 2018 Air Monitoring Network Plan and Response to Comments.
