The Secretary of State published regulations to further control emissions from"Engines and Combustion Turbines" on September 23, 2005 after public hearings on June 22 and 23, 2004 in Boston and Springfield, respectively. Comments were accepted through June 30, 2004. 4 . VOCDefinition, Tank Test and Visible Emissions Regulations addressing changes to the definition of Volatile Organic Compounds, Visible Emissions, and Tank Truck Testing were published by the Secretary of State on June 2, 2006 after public hearings on October 18 and 19, 2005 in Boston and Springfield, respectively. Comments were accepted through October 28, 2005. The regulation SIP revision package we are submitting today includes a demonstration that it has been submitted under, and conforms to the administrative requirements of section 110of the Clean Air Act. These amendments are submitted under the authority granted by Massachusetts General Laws Chapter 111, §§ 142A through 142N . Pursuant to the procedures established in section 110(k) of the Clean AirAct and the EPA procedures for SIP review(56 FR 42216), I am submitting these amendments to the Massachusetts SIP for your approval . I understand that with this submittal, Region I staffnow intends to process the backlog of previous Massachusetts SIP submittals. However, I request that EPA not take action on the amendment to 310 CMR 7.02(8), adopted on August 3, 2001 and submitted as a SIP revision on August 9, 2001 . In the 2001 reorganization of 310 CMR 7.00, existing exemptions fromthe PM emission limits in 310 CMR7 .02(8) for combustion turbines and reciprocating engines were inadvertently left out of the draft and adopted revisions . MassDEP will propose corrections to 310 CMR7.02(8) later this year . Should you or your staff have any questions regarding this submittal or wish any further information, please contact Steven DeGabriele, Director of the Bureau of Waste Prevention's Business Compliance Division, at 617-556-1120. Sincerely,

i Arleeh-CRD8M
