RE: Adequacy Status of Transportation Conformity Motor Vehicle Emissions Budgets 

Dear Ms. Kwetz: 

By letter dated January 31, 2008, the Massachusetts Department of Environmental 

Protection (MA DEP) submitted to EPA its 8-hour ozone attainment demonstration. This State 

Implementation Plan (SIP) revision identifies 2008 and 2009 summer day volatile organic 

compound (VOC) and nitrogen oxides (NOX) motor vehicle emissions budgets (MVEBs) associated 

with reasonable further progress and attainment for both the Eastern and Western Massachusetts 

8-hour ozone nonattainment areas . EPA New England has determined these MVEBs to be adequate 

for transportation conformity purposes. 

On February 5, 2008, EPA posted an announcement of availability on EPA's adequacy 

website,' for the motor vehicle emissions budgets included in Massachusetts' January 31, 2008 SIP 

revision. The SIP revision was made available for public viewing at both the EPA New England 

Regional Office and at the Massachusetts Department of Environmental Protection's Bureau of 

Waste Prevention Office . In addition, the SIP revision was made available on the MA DEP 

website.2 No comments were received during the 30 day adequacy comment period . 

The MVEBs, in tons per summer day (tpsd), are stated in the table below:

We will be publishing the Federal Register notice announcing our adequacy finding in the near
