Mining support (NAICS 2131): stack tests in Pennsylvania, 2020

28Stack 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 2020 at a Pennsylvania 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.
