  1. Proposed Airborne Toxic Control Measure for Diesel Particulate Matter from Portable Engines Greater Than50 Horsepower November 18, 2003 California Environmental Protection Agency Air Resources Board

  2. Agenda • Overview of Changes • ATCM Regulatory Proposal • Next Steps

  3. Overview of Changes • Modify fleet approach • By 2010, all engines must be certified to an off-road engine standard • Fleet standards become applicable 2013 and later • Provisions for emergency engines and low-use engines • Operating limits near schools

  4. Fleet Requirements • Fleet Definition: • Engine or group of engines under control of a Responsible Official • Company or pubic agency can have more than one Responsible Official • Engines owned by different businesses under control of one Responsible Official will be treated as one fleet

  5. Fleet Requirements (cont.) • Fleet Standards : • Applicable to all portable engines operated in California • Standards based on engine size • <175 horsepower • 175-749 horsepower • >750 horsepower

  6. Fleet Requirements (cont.) • Exclude from fleet • Engines operated in OCS only • Low-use engines • Dedicated to emergency use only • SCR equipped engines

  7. Diesel PM Standards • By 2010, all engines must be certified to an off-road engine standard • Fleet Standards • 2013 • 2017 • By 2020, full compliance

  8. Diesel PM Standards (cont.) • Engines permitted/registered after 1/1/08 • Certified to most stringent standard • Subject to fleet emission standards unless used only in emergency applications or designed low-use engine • PERP will be revised to accept applications from all engines until 1/1/08

  9. Diesel PM Standards (cont.)

  10. Emergency / Low-Use Engines • Emergency • Loss of electrical power beyond reasonable control of owner • Pumping water for flood control or fire suppression • Prevent sewage overflow • Low-Use • 50 hours or less a year

  11. Emergency / Low-Use Engines (Cont.) • Not subject to fleet requirements • By 2020, engine must be either: • Certified to Tier 4 off-road standard or • Retrofit with level-3 verified technology

  12. Incentives • Grid power • Must exceed 200 hours • Alternative engines • Operate 100 hours or more • Early purchase Tier 4 engines

  13. Operation Near School • District authorization for projects operating more than 5 consecutive days • Emergency applications not limited • Clean engines required after January 1st, 2006

  14. Recordkeeping • Recordkeeping • Limited engines affected • Alternative-fueled engines • Engines affected by electrification • Low-use engines • Engines used only in emergency applications • Requirements • Track annual hours of operation • Hour meter

  15. Reporting • Reporting • Status report due 2011 • Compliance report due 2013, 2017, and 2020

  16. Next Steps • Additional Workshops • December 2 (Sacramento) • December 4 (El Monte) • February 26, 2004 Board Hearing
