Permit Fact Sheet 

This page formerly included permit applications, instructions and general information for the Clean Air Interstate Rule (CAIR) Permit (BWP AQ 29) for facilities subject to 310 CMR 7.32.  

MassDEP is no longer accepting BWP AQ 29 applications because EPA has discontinued the CAIR Program.

For more information, please see the letter above, which MassDEP sent to affected facilities via email on December 31, 2014.
