PUBLIC NOTICE

Notice is hereby given that the Department of Environmental Protection, acting in accordance with the provisions of M.G.L. chapter 111, Section 142A through 142E, will offer for public comment the following draft Operating Permit issued pursuant to 310 CMR 7.00: Appendix C.

The draft RENEWAL Operating Permit for Blackstone Power Generation, LLC, is being issued in accordance with 310 CMR 7.00: Appendix C(6). Since the initial Operating Permit was issued in 2005, there have been several changes to the facility’s processes and emissions. These changes include, but are not limited to, software upgrades, reducing the minimum operating level, and increasing the turbine maximum rated heat capacity. As a result from these changes, the facility has reduced carbon dioxide emissions. The existing short term emission limits and annual emission limits have not changed, and the increased heat capacity of the turbines results in an increase in emissions under 1 ton per year for all air contaminants.

The purpose of the Operating Permit is to codify all of the facility's applicable requirements under the state and federal Clean Air Act, including monitoring, record keeping requirements and emission limitations, into a renewable Operating Permit. This action is required by the U.S. Environmental Protection Agency as stated in its final rule approving the Department's Operating Permit program (Federal Register Vol. 61, No. 95 Wednesday May 15, 1996).

The draft RENEWAL Operating Permit is for:
