Posted by Ed on February 5, 2007, 1:18 pm Time to spread the word and ask questions. Once this is approved, standing outside with picket signs will prove fruitless.

Here is another excerpt for the power plants web site on Air Quality, note BATC stands for "best available control technology," the word best does not mean fool-proof.
Air Quality
As a new, non major source of air pollutants, the proponent must perform an analysis
using a US EPA-approved screening computer dispersion model to demonstrate compliance with
the applicable National and Massachusetts Ambient Air Quality Standards. The proponent will
need to provide additional information in the DEIR submittal to satisfactorily demonstrate that
the project will not have significant impacts on air quality. The proponent should work with
MassDEP's Division of Air Quality to demonstrate that the project meets the requirements for
MassDEP's Non-Major Comprehensive Plan Approval pursuant to 3 10 CMR 7.02 prior to
project construction. To meet the requirements for BACT, the project is proposing to use clean
fuels. The DEIR should include information to satisfactorily demonstrate that the project meets
the Best Available Control Technology @ACT) requirements for air pollutants including anyla11
proposed combustion and post-combustion controls to demonstrate that the project will meet
these requirements.
EOEA #I3925 ENF Certificate January 22,2007
According to the comments received from MassDEP, the proponent will need to
complete a Top-down Best Available Control Technology Analysis for the proposed Billerica
Power project that uses the specific emissions limitations identified in MassDEP's comment
letter. The ENF indicates that the project will fall below applicable thresholds for federal
National Emissions Standards for Hazardous Air Pollutants for stationary gas turbines. However,
the proponent will be required to comply with the federal New Source Performance Standard for
stationary gas turbines. The DEIR must demonstrate how the project will comply with these
standards. I encourage the proponent to contact MassDEP's Division of Air Quality Control
about these and any other air quality issues.
