Description
The Washington State Department of Ecology’s Prevent Nonattainment program funds practical air pollution prevention in areas at greatest risk of failing national air quality standards. Although all of Washington currently meets those standards, some areas remain a concern. Projects must address local pollutants of concern: carbon monoxide, nitrogen dioxide, ozone, or particle pollution (PM10 and PM2.5).
Supported work includes alternatives to outdoor and agricultural burning, cleaner equipment purchases, agricultural dust reduction, and efforts to reduce single-occupant commutes. Examples include community composting, chipping, yard waste collection, orchard tear-out management, direct seed or no till farming support, and incentives for alternative transportation. Projects must estimate emissions reductions or related measurable outcomes. Community outreach, engagement, and education can support this work but cannot be its main focus.
