Attachment: Specific actions to help reduce public exposure to diesel exhaust. The Final Report of the PM2.5 Stakeholder Group was issued on October 15, 1999. This report included several categories of strategies for PM2.5 reduction which were developed during the Stakeholder process. Related WEC suggestions appear in square brackets : Category A: (Worth considerable effort by the Agency to pursue.) * Reduced Sulfur fuels for use by industry. * Develop a fuel conversion incentive program for industry to replace coal, distillate, and residual fuels oil combustion with natural gas [or other alternatives]. * Work with Ecology to tighten the current inspection and maintenance program for diesel opacity and to evaluate potential of routine on-road testing. (Washington State opacity testing is still at a "starter" level. Other states with diesel opacity testing have much more rigorous standards. Nothing appears to have been done to date on this strategy). Category B: (Worth some effort by the Agency to pursue.) * Cleaner fuels and promotion of good operation and maintenance for construction equipment.
* Use cleaner fuels for marine engines in the Puget Sound Region along with improved operations and maintenance of marine diesel engines
Category C: (Difficult to implement.)
* Require California diesel (lower aromatics) in the Puget Sound Region.
* Request EPA to certify clean air retrofit kits for heavy duty diesel trucks. [Then require the retrofit in selected classes of vehicle]
* Develop retrofit/rebuild incentives with Ecology and fleets. (For public and publicly contracted diesel-fueled vehicles).
In addition to the PSCAA Stakeholder strategies, other variations on emission reduction strategies are possible, including:
Require replacement of all diesel-fueled service vehicles in selected areas of dense pedestrian traffic with Alternative Fuel Vehicles (Includes SEATAC and other airports).
Require installation of anti-idling devises on certain classes of diesel vehicles.
