  1. California Environmental Protection Agency Air Resources Board Diesel Risk Reduction Plan

  2. Why should we reduce emissions from diesel-fueled engines? • Diesel emissions are a significant health concern • Public exposure and risks are high • Effective diesel emissions controls are readily available

  3. There are 1.25 Million Diesel Engines in California • Mobile • on-road - 687,000 • off-road - 547,000 • includes portable equipment - 49,000 • Stationary • emergency/standby - 11,000 • prime - 5,000

  4. 93% of Diesel PM is Emitted by Mobile Sources Off-Road On-Road 25,000 TPY Total Diesel Emissions Year2000

  5. Diesel PM Responsible for 70% of Year 2000 Statewide Risk from Air Toxics Emissions 30% 220 / million risk 70% 540 / million risk Diesel Exhaust PM10 (70%)1,3 Butadiene (10%) Benzene(8%) Carbon Tetrachloride (4%) Formaldehyde (3%) Hexavalent Chromium (2%) All Others (3%)

  6. Trap Effective Reduction Options are Readily Available • Diesel traps are effective for both new and existing engines • Alternative technologies • electrification • fuel cells • Alternative fuels • CNG, LNG, LPG, dual-fuel • Alternative diesel formulations/additives • Engine modifications

  7. Diesel Risk Reduction Plan • Adopted in September 2000 • Conclusions & Recommendations: • Diesel PM Most Significant Air Toxic in CA • Diesel PM Reductions are Feasible & Necessary • Examine All Diesel Categories & Usage • Regulatory & Voluntary Strategies

  8. The Diesel Risk Reduction Plan • Reduce emissions from new mobile, portable, and stationary engines • Reduce emissions from existing mobile, portable, and stationary engines • retrofit where economically reasonable • Provide very low-sulfur diesel fuel (15ppm) for diesel traps • Undertake demonstration programs; develop incentive programs • Work with stakeholders and International Retrofit Advisory Committee

  9. Control Measures • Mobile on-road and off-road engines • Stationary and portable engines • Fuel requirements • Requires federal action for some categories • Adoption beginning in 2002

  10. Mobile Source Measures • Lower new engine standards for on- and off-road vehicles • Retrofit of existing on- and off-road vehicles when makes sense • Control of in-use emissions for on- and off-road vehicles • Pleasure craft standards and test procedures for HDV certification • Implementation (2002 -2008)

  11. Stationary and PortableEngine Measures • Address both new and existing engines • Address emergency/standby, industrial, agricultural, portable, TRUs, and <50hp engines • Implementation between 2002-2005

  12. Stationary/Portable Demonstrations • Prime - plan to test prime engines • Emergency Standby - temperature profiles, emissions testing • Portable - Construction, Oil Well Drilling & Servicing

  13. Agricultural Efforts • Outreach - 8 meetings January - March, 2001 • Agricultural Working Group (AgWG) - first meeting May 30, 2001 • Demonstration - UCD and AgWG

  14. Fuel Measure • Very low-sulfur CARB diesel fuel (15 ppm) • Full implementation by 2006

  15. Federal Action Is Critical • Locomotives • Commercial marine vessels • New farm and construction equipment <175 hp • New heavy-duty vehicle standards • Low-sulfur fuel specifications

  16. Reductions from Existing Engine Retrofits are Critical • In 2010, 85% of the reductions come from retrofit of existing engines

  17. Our Approach for Control of Existing Engines • Must be sensible in determining which existing engines should be retrofitted • Must be economically reasonable • Numerous demonstration projects planned • Develop voluntary and incentive-based programs

  18. International Retrofit Advisory Committee • Advises ARB on feasible and effective ways of implementing retrofits • 40 technical experts and stakeholders • Engine manufacturers, control manufacturers, fleet operators, diesel fuel suppliers, construction, agriculture, academia, environmental organizations, air pollution control districts, and U.S. EPA

  19. Benefits of Plan • Significantly reduces diesel PM emissions • 75% reduction in potential cancer risks by 2010, 85% by 2020 (see next slide) • Decrease in noncancer health effects (asthma, bronchitis) • Improve visibility • Reduce “soiling”

  20. Benefits Proposed Plan Reduces Diesel PM Emissions and Risk by 75% in 2010 and by 85% in 2020

  21. Cost of Controls • Sensitive to the economic impacts • Costs comparable to other major ARB programs • Conduct detailed cost analysis as measures are developed • Develop incentive-based programs

  22. Incentives • Carl Moyer Program • Established Marketing & Incentives Workgroup (IDRAC)

  23. Process Scoping Workshops/ Individual Meetings Public Outreach Meetings Diesel Risk Reduction Plan Public Input Draft Regulations Public Workshops ARB Public Hearings Proposed Regulations
