WRAP Offroad Mobile Source Retrofit Program

The Western Governors' Association (WRAP) Board Meeting discusses the implementation of retrofit programs to reduce offroad emissions and achieve environmental and public health benefits. This includes identifying the sources with the greatest impact, exploring retrofit options, and showcasing successful retrofit programs across different states. The meeting also discusses funding sources and other incentives to encourage industry compliance.

  1. WRAP Offroad Mobile SourceRetrofit Program Lee Alter Western Governors’ Association WRAP Board Meeting Salt Lake City November 10, 2004

  2. Background • Offroad emissions expected to exceed onroad by 2013 for NOx and already exceed onroad for PM2.5. • Although new and stringent standards are being implemented for offroad sources, phase-in does not begin until 2011 and may not be complete until 2030+. • Retrofit programsaccelerate environmentaland public health benefitsand provide flexibility toimplementation plansand industry compliance.

  3. Background • The WRAP Board has identified offroad emission reductions as necessary for achieving “reasonable progress” and has called for EPA and WRAP members to collaborate on diesel retrofit programs. • Approximately $140,000 of WRAP funds have recently been committed to promote retrofits in the region. • Technological and administrative options for retrofits are available and rapidly growing. • Offroad retrofits pose unique challenges due to wide range of sizes, applications, operating conditions, and fuel attributes.

  4. So What Can the WRAP Do?

  5. Identify Which Offroad Sources Are Having the Greatest Impact, and Where

  6. Class I Areas with the Greatest Contribution of Agricultural Equipment to Nearby NOx Emissions (1996) 2 3 6 1 7 8 4 10 9 5

  9. Identify Appropriate Retrofit Options

  10. Here the term “retrofit” includes … • Retrofit / Aftertreatment • Catalysts, filters, crankcase controls, EGR • Refuel • ULSD, biodiesel, emulsion, electrification, CNG • Rebuild • Tune-up, repair, certify existing engine • Repower • Install new engine in existing equipment • Replace • Idle control

  11. Aftertreatment Technologies • Rapidly evolving • Must be tailored for specific applications • Need experience, demonstration, and verification • Diesel oxidation catalysts (DOCs) • Most widely used technology to date • Applicable to virtually all engines and vehicles • No maintenance required • Can reduce PM emissions by 25-50% depending on fuel sulfur and the soluble organic fraction of PM • Diesel particulate filters (DPFs) • Widely applied, but some applications (due to low exhaust temp) require active regeneration (not yet widely practical)

  12. Aftertreatment Technologies • Crankcase controls • Selective catalytic reduction (SCR) • Due to reductant storage requirements, use has been limited to large engines (e.g., ships and locomotives), but capable of 60-90% reduction • Lean NOx catalysts • More broadly applicable, but only modest NOx reductions • NOx adsorber catalysts • Under development, but capable of 90% NOx reduction • Currently operate over narrow temperature ranges

  13. Retrofit Effectiveness

  14. Identify Administrative Options and Incentives

  15. Sample of Offroad Retrofit Programs • Federal • EPA Idle Reduction Program • EPA SmartWay Transport (ground freight) • California • Portable engines > 50 hp by 2020 (proposed rule) • Various locomotive and commercial marine and port initiatives • Various projects funded by districts & state (Carl Moyer program) • Washington • All construction projects funded by state (proposal being developed) • Working with cruise lines to put in shore-line power • Converted cranes to electrical power • Anti-idling for switcher locomotives in Vancouver

  16. Sample of Offroad Retrofit Programs • Oregon, Colorado, and probably others • Tax credit for retrofits (35% in OR) • Texas • Port of Houston applying DOC/SCR systems and fuel additives for 50-250 vehicles (cranes, gantries, etc.) • Various refueling, repowering, and retrofit projects funded by state • Massachusetts • All construction projects funded by the state or MBTA • DOCs and 500 ppm S fuel for 15-22 locomotives ($1.25M) • ~200 construction vehicles involved with the Big Dig • Connecticut • All construction vehicles > 60 hp involved in the New Haven corridor project

  17. Sample of Offroad Retrofit Programs • Georgia • Construction incentives/requirements at Hartsfield Int’l expansion • New York City • All city-owned/leased vehicles > 50 hp must use ULSD and best available technology • Chicago • Auxiliary power units to reduce locomotive idling • Mt. Ranier • Biodiesel and exhaust controls for trucks and equipment

  18. Funding Sources & Other Incentives • Public funding • EPA grants (Voluntary Diesel Retrofit Program, Mobile Source Outreach Assistance Grants) • CMAQ funds (not applicable to fuels) • USDA/NRCS Environmental Quality Incentives Program • State and local grants and tax incentives • Government actions • Retrofit publicly-owned vehicles • Modify contract awarding procedures • Use supplemental environmental projects (see StEPP Foundation) • Retrofit in lieu of paying fines for smoke violations • Exempt retrofitted vehicles from smoke inspections, use restrictions, and vehicle registration fees and taxes • Publicly recognize fleet operators who retrofit

  19. Funding Sources & Other Incentives • Implementation plan credits • Most or all of the above actions can produce credits towards use in meeting emission reduction targets in state and tribal air quality implementation plans. • EPA allows up to 3% of the total emission reductions in a SIP to be from voluntary mobile source programs.

  20. and …

  21. Draft and update guidance … • Containing the prior information • Describing the elements of a successful retrofit program • Provide direct, expert technical support to parties interested in retrofit opportunities • Project planning, equipment specs, emission calculations, etc. • Help identify such opportunities and recruit participants • Provide targeted and/or public outreach, as requested

  22. WRAP Contractor Support • Emissions Advantage, LLC • Established for the specific purpose of providing program and technical assistance to diesel retrofit programs • It’s three principals have over 85 years of experience in motor vehicle emission controls • Major contract tasks • Survey WRAP participants for needs, wants, and potential opportunities • Survey equipment owners for awareness, motivation, and requirements • Draft and update guidance • Track and report on issues and opportunities to MSF • Provide technical and outreach support upon request • Conduct workshops for WRAP members and others
