The Tribal Air Program has been in operation since 2001, and the Natural Resources Department has administered the program under a Direct Implementation Tribal Cooperative Agreement for eight years. The Natural Resources Department has successfully operated and maintained a PM 2.5 program on tribal lands since 2003. Ambient ozone levels are continuously monitored throughout the year. Ozone data is exported in real-time to the state of Massachusetts ozone program for review and validation. The data collected through the Tribe’s ozone monitoring program is of great importance to tribal and public health, without which ozone air quality for the entire Cape Code region could not be validated. This data is uploaded to a national database where it becomes accessible to professional agencies and the general public.
