Primary metal manufacturing (NAICS 3314): stack tests in California, 2021
- 3Stack tests
A stack test measures what a source actually emits, at the stack, against the limit in its permit. Each row is one stack test recorded during 2021 at a California source whose primary industry code is NAICS 3314. A facility filing more than one industry code is counted under the first one on its record.
