Sunlight Nitrogen OxidesVolatile Organic

Compounds

Ozone

Pollutants “bake” together in direct sunlight, forming ozone

CLEANER AIR FORIMPACTED COMMUNITIES

Community Air Protection – AB 617 (2017) Measure & reduce localized air pollution in

disadvantaged communities

Portside Environmental Justice Community Barrio Logan, Logan Heights, Sherman Heights,

& western National City

Community Emissions Reduction Program Incentives, regulatory, land use, transportation
