*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. The 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.1 NSR offset 

ratio requirements will remain at 1.2 to 1 (rather than the 1.15 to 1 ratio required for moderate 

areas). The major source thresholds for RACT will not change. (RACT regulations are discussed 

in detail in Section 6.) 

 

1 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.

** 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. Deleted: .
