MassDEP Ambient Air Quality Monitoring Network & Annual Plan

Learn about which pollutants and parameters the agency measures at specific monitoring sites, and why.

About the Monitoring Network & Plan

The Massachusetts Department of Environmental Protection (MassDEP) operates a network of 22 ambient air quality monitoring stations at locations across the state. The Wampanoag Tribe of Gay Head (Aquinnah) operates an ozone monitoring station on Martha's Vineyard. Each year, MassDEP is required to submit an Annual Ambient Air Quality Monitoring Network Plan to the U.S. Environmental Protection Agency (EPA). This document and its attachments are subject to a 30-day public comment period before MassDEP submits them to EPA for review and approval.

The annual network plan describes to EPA which pollutants and other parameters MassDEP measures at its various ambient air monitoring sites and why they are measured at those specific locations. It also describes changes in the network - including new and closed locations, and new and discontinued measurements at existing locations - since the last network plan, as well as proposed changes in the network over the next 18 months.

MassDEP also must conduct an assessment of the Massachusetts Ambient Air Quality Monitoring Network every five years to determine whether it meets the objectives defined in EPA regulations.

This page summarizes the annual network plan and five-year network assessment. See the full network plan and attachments, along with instructions for submitting comments.
