Air-emissions sources in Tuolumne County, California
- 4Facilities
Tuolumne 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.
