Re: Massachusetts State Implementation Plan Amendment 

Dear Mr. Spalding: 

Enclosed for your review and approval, as an amendment to the Massachusetts State Implementation Plan 

(SIP), pursuant to the requirements of Section 110 of the Clean Air Act Amendments of 1990, are one 

attested copy of amendments to the Massachusetts Air Pollution Control Regulations, 310 CMR 7.00, et 

seq. and other administrative and technical documentation required in a SIP submittal. These 

amendments were promulgated pursuant to the authority granted by Massachusetts General Law c. Ill , 

Section 142 A through M. Specifically, the regulations amended 310 CMR 7.36, the Transit System 

Improvements regulation. 

DEVELOPMENT OF THE SIP REVISION 

The Department of Environmental Protection (MassDEP) proposed amendments to 310 CMR 7.36 on 

August 3, 2012. MassDEP held public hearings on the amendments on September 13, 2012. The 

comment period ended on September 24,2012. The amendments were filed with the Secretary of State 

on October 10, 2013 and were effective on October 25, 2013, upon publication in the Massachusetts 

Register. 

A copy of the proposed amendments to the regulation was sent to EPA for review and comment 30 days 

prior to the public hearing. Comments raised by parties during the public review process have been 

summarized and are contained in this SIP revision package along with MassDEP's response to those 

comments. 

The final amendments to the regulation were not modified from the proposed amendments to the 

regulation. 

This information is available in alternate format. Call Michelle Waters-Ekanem, Diversity Director, at 617-292-5751. TDD# 1-866-539-7622 or 1-617-574-6868

SUMMARY 

The Department made three amendments to 310 CMR 7.36. The first amendment deletes the requirement 

that the Massachusetts Department of Transportation (MassDOT) complete the final design of the Red 

Line/Blue Line Connector from the Blue Line at Government Center to the Red Line at Charles Station 

by December 31, 2011. Although 310 CMR 7.36 (2)(i), as adopted in 2006, required MassDOT to 

complete the final design of the Red Line/Blue Line Connector, the regulation did not require that the 

project be constructed. Therefore, removing from the design requirement from the regulation will not 

result in air quality impacts. The second amendment to the regulation lengthens the existing public 

process requirement that MassDEP hold a public meeting on the annual update and status report within 60 

days of its July 1st submittal date to 75 days to avoid conflicts with the Labor Day holiday. The third 

amendment replaces all references to the Executive Office of Transportation (EOT) with the 

Massachusetts Department of Transportation (MassDOT). 

Therefore, pursuant to the procedures and deadlines established by the Clean Air Act amendments of 

1990 Section 110(k) and the EPA procedures for SIP review (56 FR 42216), I am submitting for your 

approval this amendment to the Massachusetts SIP. 

If you or your staff have any questions regarding this submittal or need any additional information, please 

contact Christine Kirby of the Bureau of Waste Prevention at (617) 292-5631.
