Mining support (NAICS 2131): stack tests in Louisiana, 2023

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 2023 at a Louisiana source whose primary industry code is NAICS 2131. A facility filing more than one industry code is counted under the first one on its record.
