Sources that carry it
3 sourcesStatewide point layer of Massachusetts facilities subject to air source registration, greenhouse-gas reporting, or air operating permit requirements.
Florida DEP's statewide Air Resource Management System (ARMS) facility layer, filtered to STATUS='ACTIVE'. Point locations of every facility that has requested air permitting from FDEP's Division of Air Resource Management, including facilities administered under the 8 FDEP-delegated local air programs (Miami-Dade, Broward, Hillsborough, Orange, Duval, Palm Beach, Pinellas, Sarasota) — verified via the OFFICE field and AIRS_ID county-FIPS prefixes; all local-program facilities are already present in this statewide layer, so no separate county appendix is needed. 3,476 active facilities as of 2026-07-24, against a predicted 4,500 ± 40%.
TCEQ's Point Source Emissions Inventory, drawn from the State of Texas Air Reporting System (STARS): an annual survey of chemical plants, refineries, electric utilities, and other industrial sites that meet the emissions-reporting threshold under 30 TAC 101.10. Each row is a (regulated entity, reporting year) observation carrying the company/account identity, site location, and site-wide annual tons-per-year emissions for the EPA criteria pollutants (CO, NOx, Pb, PM, PM10, PM2.5, SO2, VOC). The multi-year state-summary workbook (2010-2024, 28,867 rows) is fetched in full and covers only the AIRS Attribute for Texas.
