SUPPLEMENTARY INFORMATION:

On September 18, 2000 (65 FR 56278-56283), EPA proposed a revision to the Massachusetts State Implementation Plan (SIP) for Ozone and Carbon Monoxide, for a City of Cambridge Vehicle Trip Reduction Program in the Metropolitan Boston Air Pollution Control District. The revision consists of Massachusetts's new state regulation 310 CMR 60.04—“City of Cambridge Vehicle Trip Reduction Program.”

The proposal provided a 30 day public comment period that was originally scheduled to end October 18, 2000. In response to a request from the Massachusetts Department of Environmental Protection as well as a request from a representative for the City of Cambridge, EPA is extending the comment period for an additional 60 days.
