Why should we reduce emissions from diesel-fueled engines?
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

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

The Diesel Risk Reduction Plan 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

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

Mobile Source MeasuresMobile 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)

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

vessels New farm and
construction equipment <175 hp
New heavy-duty vehicle standards Low-sulfur fuel specifications

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

Our Approach for Control of Existing Engines
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

International Retrofit Advisory Committee
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

Benefits of Plan 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”
