The South Coast Air Quality Management District recently took a key step in setting wide-ranging goals to address air pollution in the eastern Coachella Valley, leaving local residents and politicians cautiously optimistic for the health of communities that have suffered from poor air quality for years.

The new benchmarks, adopted on Dec. 4, come as part of the area’s draft community emissions reduction plan, which is the result of AB617, passed in 2017. In the eastern Coachella Valley, the program will look to reduce nitrogen oxides by 45%, diesel particulate matter by 77% and PM10 — particulate matter that is 10 micrometers or smaller — by 2.4 tons per year, all by 2030.
