ADEQ's "AQD Permits" ArcGIS FeatureServer layer (owner adeq_gisnp) — a facility ("Place") level registry of Arizona Department of Environmental Quality Air Quality Division permitted sources, statewide except Maricopa, Pima, and Pinal counties (which run their own delegated air-permitting programs). Each of the 408 rows is a permitted facility classified via STATE_CLAS as Major Source, Minor source, or Synthetic Minor (two sub-variants) — matching the Chubb Description's major (>100 tons) / minor (<100 tons) criteria pollutant threshold almost verbatim. Regenerated daily per ADEQ's own Hub listing. No address fields are published (only LATITUDE/LONGITUDE); ds_street/ds_city/ds_zip are always blank while ds_lat/ds_lon are 100% filled.

ADEQ's statewide facility-level ArcGIS registry of place-verified underground storage tank facilities, including active and inactive facilities and their locations.
