spring 2009 updates

Spring 2009 Updates

Transportation conformity


STAQS 2009

Fuel Waivers / Renewable Fuels Standard rule

Southeast Diesel Collaborative

Recovery Act Diesel Program

transportation conformity
Transportation Conformity
  • Ozone Conformity Amendments in progress
  • Latest Guidance Documents Published
    • Latest Planning Assumptions - Dec 2008
    • Conformity SIP – Jan 2009
    • Transportation Control Measure Substitution and Addition - Jan 2009
transportation conformity1
Transportation Conformity
  • Proposed rule published May 15, 2009 for implementation in PM2.5 and PM10 nonattainment and maintenance areas and to address hot-spot requirements
    • Proposed rule and fact sheet available at:
    • Additional PM2.5 Quantitative Hotspot Guidance will be released with MOVES
transportation conformity sips
Transportation Conformity SIPs
  • Working with states to get updates made and to remove unnecessary SIP triggers (flexibility offered by SAFETEA-LU)
  • AL SIP has been finalized
  • SC and KY have SIPs in-house under review
moves update

MOVES Update

Motor Vehicle Emissions Simulator

moves update1
MOVES Update
  • MOVES can estimate emissions for on-road and nonroad mobile sources, cover a broad range of pollutants, and allow multiple scale analysis--from fine-scale to national inventory estimation
  • Replacement for MOBILE6 and NONROAD for all official analyses associated with regulatory development, statutory compliance requirements, and national/regional inventory projections
  • Draft version of MOVES now available-Draft is not approved for use in State Implementation Plans or conformity determinations, but modelers are encouraged to use the model and provide comment to EPA. Final version of MOVES for car and truck emissions is planned for late 2009
  • Web info at:
what should you do now
What Should You Do Now?

Work now to develop the required input databases for MOVES! Use these for the final version.

Updatecomputer hardware

Dual-core processor (faster is better)

At least 1 GB memory (more is better)

At least 40 GB storage (more is better, output files can be very large )

Consider setting up a distributive network (specs of “master” computer are key)

Windows XP or 32-bit Vista

NOTE: Current version of MySQL does not work on 64-bit Vista

Provide feedbackon Draft MOVES 2009. Early feedback gives OTAQ more time to make revisions

what should you do now1
What Should You Do Now?

Build staff expertise in relational databases and MYSQL

Not needed for simple runs

Some basic knowledge gives users flexibility to customize outputs and view inputs

In-house expert would be helpful for more advanced analysis

emergency fuel waivers
Emergency Fuel Waivers
  • Under very limited circumstances, federal fuel requirements can be waived per CAA section 211(c)(4)(C).
  • Most common for fuel disruption related to natural disasters or other “acts of God”
  • Regional office can facilitate, so please:
    • Remember to contact Region 4 in addition to EPA HQ
    • Provide updates to Region 4 NOW for Emergency Contacts at your agency if changes from last year.
  • Visit EPA’s website at for more information for contacts, criteria, and Q&A’s.
  • 2008 was active season - be prepared !!
renewable fuels standard rfs
Renewable Fuels Standard (RFS)
  • Proposal on May 5, 2009 to revise National RFS program as required by Energy and Independence Security Act (EISA) of 2005
  • Establish the revised annual renewable fuel standard (RFS2) for new specific volume standards for cellulosic biofuel, biomass-based diesel, advanced biofuel and total renewable fuel. Increases beginning in 2008 (9.0 Bgal total) to reach 36 Bgal by 2022
  • Analyzed lifecycle analysis of greenhouse gas emissions from renewable fuels and the feedstocks used to produce them
  • Regulatory requirements apply to both domestic and foreign producers and importers of renewable fuel
other current fuel items
Other Current Fuel Items
  • April 21, 2009 – Notice of receipt of waiver application to increase the allowable ethanol content of gasoline to 15% - EPA has 270 days to grant or deny the waiver
  • May 6, 2009 – President established the Biofuels Interagency Working Group, comprised of EPA, DOE, and USDA to develop biofuels market development program, coordinate biofuel infrastructure policies, study biofuel lifecycle and help existing producers secure credit/financing
  • May 19, 2009 – Notice of upcoming joint rulemaking by EPA and USDOT (NHTSA) to establish vehicle greenhouse gas emissions and Corporate Average Fuel Economy (CAFÉ) standards
