Utilities (NAICS 2211): stack tests in Maryland, 2023

15Stack 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 2023 at a Maryland source whose primary industry code is NAICS 2211. A facility filing more than one industry code is counted under the first one on its record.
