Fabricated metal product manufacturing (NAICS 3328): stack tests in Indiana, 2025
- 6Stack 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 2025 at a Indiana source whose primary industry code is NAICS 3328. A facility filing more than one industry code is counted under the first one on its record.
