Air Quality Alert - Orrington Fire

Ground-level particle pollution concentrations are expected to reach the 'Unhealthy for Sensitive Groups' (USG) level in the Eastern Interior and Mid-Coast Regions for today and tomorrow according to Air Quality Meteorologists at the Maine Department of Environmental Protection.

Smoke from a fire in Orrington is causing high particle pollution levels at local monitors, one of which was sited by the Maine DEP on Wednesday to measure localized air quality. The winds in the Penobscot River Valley are expected to remain from the south over the next 24 hours. Maine DEP is issuing this air quality alert as authorities anticipate that the fire is expected to burn for at least one more day. While valley locations will be especially susceptible to higher levels of particle pollution, all areas in the vicinity should take precautions.
