Oil and gas extraction (NAICS 2111): stack tests in Arkansas, 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 Arkansas source whose primary industry code is NAICS 2111. A facility filing more than one industry code is counted under the first one on its record.
