Nitrogen Dioxide Monitoring
Tracking Air Quality Changes at Boston Logan
Between 1982 and early 2012, Massport collected NO2 concentration data at numerous locations both on the Airport and in neighboring residential communities. The purpose of this monitoring program was to track long-term trends in NO2 levels and to compare the results to the NAAQS for this pollutant. Massport determined that the Logan NO2 Monitoring Program had achieved its objectives with the significant and stable decrease in NO2 emissions since 1999. Massport discontinued the program in early 2012.
Nitrogen Dioxide Monitoring Results
Centerfield Taxiway Air Quality Monitoring Study
In 2008 Massport began a $1.6 million air quality monitoring study in and around Logan Airport in compliance with its Massachusetts Environmental Policy Act (MEPA) Section 61 findings for the centerfield taxiway component of the Logan Airside Improvements Project.
The intent of the study is to assess air quality changes related to the operation of the new centerfield taxiway by measuring air quality data in communities around Logan Airport both before and after the centerfield taxiway became operational, with an emphasis on ambient (i.e., outdoor) levels of particulate matter and hazardous air pollutants.

Nitrogen Dioxide Emissions by Airline
As part of the reporting process, the Air Quality Initiative calls for an itemization of nitrogen dioxide emissions generated by activities at Logan Airport according to the individual airline operator.
