Approval and Promulgation of Air Quality Implementation Plans; Massachusetts; Transit System Improvements

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Massachusetts. This revision removes from the SIP the design aspect of the Red Line/Blue Line Connector transportation control measure as a requirement in the Massachusetts SIP, without substitution or replacement, and in addition implements administrative changes that lengthen the existing public process requirement so that a public meeting on the annual update and status report be held within seventy- five days of its July 1st submittal date and replaces references to the Executive Office of Transportation (EOT) with references to the Massachusetts Department of Transportation (MassDOT). This action is being taken in accordance with the Clean Air Act.
