*NSR and RACT  

MassDEP regulation, 310 CMR 7.00 Appendix A: Emissions Offsets and
Nonattainment Review, contains the Massachusetts New Source Review (NSR)
program for stationary sources of NOx and VOCs.  MassDEP intends to
maintain tThe major source applicability thresholds of potential-to-emit
(PTE) 50 tons per year of volatile organic compounds and PTE 50 tons per
year of NOx that applied to serious 1-hour ozone nonattainment areas,
also apply under the 8-hour ozone standard. instead of the PTE 100 tons
per year NOx threshold, which it could adopt as a moderate 8-hour
nonattainment area.  NSR offset ratio requirements will remain at 1.2 to
1 (rather than the 1.15 to 1 ratio required for moderate areas). 
MassDEP will also maintain its existing The major source thresholds for
RACT will not change. (RACT regulations are discussed in detail in
Section 6.)

** Enhanced Inspection and Maintenance and On-Board Diagnostics Program 

The Massachusetts Enhanced Emissions and Safety Test (I&M program)
requires most model year 1984 – 1995 vehicles to be tested on a
dynamometer, and model year 1996 and newer vehicles to be tested with
on-board diagnostic (OBD) equipment. The 2008 RFP emissions estimate are
based on the existing program. The contract for the current program
expires on September 30, 2008 and MassDEP intends to adopt program
revisions that will take effect October 1, 2008.  MassDEP will amend its
current regulation to make program revisions and submit the amended
regulation to EPA as a separate SIP amendment. The SIP amendment will
demonstrate that the revised program effectively replaces the emission
reductions required by the existing program, and that that revised
program will meet the requirements of EPA’s I&M rule.  . 

 EPA’s Final Rule to Implement the 8-Hour Ozone National Ambient Air
Quality Standard - Phase I , 69 FR 23952, April 30, 2004, allowed areas
to adopt the major source thresholds that applied to their 8-hour
standard classification, even though the thresholds might be less
stringent than those that applied to the area under the applicable
1-hour ozone standard classifications. In December 2006, the U.S. Court
of Appeals for the D.C. Circuit vacated EPA’s Phase 1 rule, holding
that parts of the rule violated provisions of the CAA. The count
concluded that the provision allowing an area to adopt less-stringent
major source thresholds constituted illegal “backsliding.” Even
prior to this court decision, MassDEP decided to retain its 1-hour NOx
RACT threshold of PTE 50 tons, rather than adopt the less-stringent PTE
100 ton threshold that EPA’s rule would have allowed had it not been
vacated.
