Chemical manufacturing (NAICS 3252): stack tests in Pennsylvania, 2024

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 2024 at a Pennsylvania source whose primary industry code is NAICS 3252. A facility filing more than one industry code is counted under the first one on its record.
