Why is Diesel Such a Problem in Our Area?

Diesel engines are inexpensive and durable, making
them a popular choice.

As neighboring states enact health-protective legislation, their old engines are sold in Oregon. We now have an older fleet than even federal emissions
models assume.

What are the Solutions to Our Diesel Crisis?

Keeping a Promise: In 2007, the Department of Environmental Quality promised to dramatically reduce diesel in Oregon. Sixteen years later, diesel pollution
has been reduced by only 2%. Now, the DEQ needs to keep its promise and get far more aggressive in tackling diesel.

Transition to Clean Technology: Construction equipment and diesel hotspots like distribution centers are the largest sources of diesel in Portland. The
solution is simple – new diesel technology reduces
carbon and emissions by nearly 95-99%. We need our
leaders to commit to closing a regulatory loophole
and spur an aggressive program to transition older
diesel to newer models.

Support the Clean Diesel Fund: Heavy diesel equip-
ment is expensive — construction companies should not face the burden of transition alone. The Clean Diesel Fund, which has already supported the transition of many older diesel trucks, needs to be replenished to provide grants to companies committed to cleaning up its fleet. This will bring a huge return on investment, as the EPA suggests that changeover will save $20 for every $1 spent, mostly from saved health care costs. With newer equipment, our state will save billions.

Permits Open For Comment

Have Your Voice Heard! Oregon’s Department of Environmental Quality is constantly considering permits for businesses and more that will affect our air quality. They need to hear from you! Go here to see permits under consideration, then find one that is related to air quality and may affect your community, click on it and follow the directions for submitting comments. For questions or additional guidance, contact Tori!

Report an Odor

Odors can often be an indicator of the presence of toxic emissions from industrial facilities. Whether they are toxic or just create a nuisance, they can be a violation of state issued air permits. For that reason, logging odor complaints is an effective means to mitigate negative impacts from industrial facilities in our neighborhoods.
