Air-emissions sources in Sonoma County, California
- 23Facilities
Sonoma County, California is designated nonattainment or maintenance for at least one national ambient air-quality standard, so a new or expanding source here faces stricter permitting than the same source would in a county that meets every standard. The designation belongs to the county, not to any facility on this page.
