The Massachusetts Department of Environmental Protection agency (MassDEP) authorized the air quality pilot test to take place between 8 p.m. and midnight on Tuesday, June 26.
MassDEP is advising residents near the General Chemical Company facility to keep windows and doors closed. There are several apartment complexes in that neighborhood.
MassDEP said it will shut down the test, if air quality monitors show that pollution levels approach health-based levels. Monitors and containers will be in place to catch dust and volatile organic compounds.
MassDEP said General Chemical must submit a test report on the test by July 13.
