Chemical manufacturing (NAICS 3253): stack tests in Louisiana, 2026

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 2026 at a Louisiana source whose primary industry code is NAICS 3253. A facility filing more than one industry code is counted under the first one on its record.
