Professional, scientific and technical services (NAICS 5413): stack tests in Michigan, 2025

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 2025 at a Michigan source whose primary industry code is NAICS 5413. A facility filing more than one industry code is counted under the first one on its record.
