USEPA Analysis: Approach• 2011 USEPA Analysis• Used the CAMx Model• Modeling projected from a 2002 base inventory to
2016 Includes the benefits from the “proposed transport
rule”• Contributions were calculated for monitors above
70 ppb • Caveats:
Modeling does not reflect the latest base year and projected emissions inventories.
• Conclusion Modeling is Dated, but Informative

Success Stories
• Goal: A source for OTC states of successful projects to reduce emissions from mobile sources
• Projects involve Marine, Rail, Bus, and Truck categories
• Though PM focused, some projects provide NOX benefits Projects with biggest NOX benefits:
• Tugboat repowering, • Locomotive repowering and Idling reduction • Vehicle Idling

Success Stories: Background
• Funding Sources: DERA (Diesel Emissions Reduction Act) ARRA (American Recovery & Reinvestment
Act)
• Voluntary or Required Actions General Conformity VALE (Voluntary Airport Low Emissions) Port Plans

Aftermarket Catalyst Recommendation
• EPA’s policy was set in 1986 and has not been updated to reflect improvements in technologies & emission standards
• OTC submitted a finalized recommendation for an updated catalyst program to EPA in April, 2011

Aftermarket Catalyst White Paper
• Goal: To improve the emission benefit analysis of the catalyst program in the OTR.
• Process: Analyzed 2010 I/M program data from MA,
MD, NH, NJ, NY and PA Developed statistical model to estimate data
for entire OTR Used test data from MECA studies to estimate
emission benefits

Diesel I/M• Lead: NESCAUM Heavy Duty Workgroup• Goal: Proposal to USEPA for SIP Credit for I/M Programs• Results in Emission Reductions of:
Oxides of Nitrogen (NOX) Fine Particulate Matter (PM2.5)
• Methodology: MOVES includes deterioration Deterioration mitigated through
maintenance and deterrence through I/M
Translates to emissions benefits• Activities:
Gathered & analyzed studies that quantify effect of repairs Developed white paper Working with OTAQ Determining if additional data is needed

Light Duty GHG Rule
• Covers Light Duty Vehicles MY 2017-2025• Reduces GHG emissions by 2 billion
metric tons through increased vehicle efficiency and improved EV penetration
• Emission Changes considered: Increased Vehicle Usage - NOX increases VOC and NOX reductions from the refinery
sector Increased Electricity Generation due to EV
Charging - NOX increases
