Environmental inspection date

Statewide Massachusetts registry extract of sites with active aboveground storage tank Use Permits, obtained from DFS through a public-records request and rolled up from permit records to site grain.

Public ArcGIS layer of active New Hampshire air-permit facilities and their permit classifications, industry codes, inspection dates, addresses, and coordinates.

EPA ECHO public national facility-level compliance and enforcement data delivered through live REST services, generated query CSVs, the ECHO Exporter full ZIP, and coordinated national download dictionaries. Covers CAA, CWA/NPDES, RCRA, SDWA, and federal enforcement records; this bounded Source excludes TRI release quantities and other emissions inventories.

EPA PFAS Analytic Tools 'Industry Sectors' layer (PAT_Industry_Sectors, layer 3 of the public PFAS_Analytic_Tools_Layers ArcGIS FeatureServer) -- facilities with federal CAA/CWA/RCRA permits operating in industry sectors that literature review indicates may handle or release PFAS, per EPA's ECHO methodology. This is the live feed backing the interactive PFAS Analytic Tools dashboard's Industry Sectors tab. 714 facilities as of 2026-08-12, dominated by Part 139 airports (536) plus smaller NAICS/SIC-driven categories (waste management, chemical manufacturing, printing, metal coating, etc.). Note: this live layer is significantly narrower than the ~120,000-facility figure cited in EPA's marketing description of the tab's methodology -- see the Source .md for full reconciliation.

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.

VA DEQ EDMA 'Registered Petroleum Tank Facilities' MapServer layer 102 (the combined aboveground/underground petroleum tank registry, 25,579 facilities), filtered to VA's regulated AST facilities via FAC_ACTIVE_AST>0 AND FAC_RISK_RANK populated — 664 facilities. This matches DEQ's published 'more than 600 AST facilities' (the risk-ranked, actively-inspected set; 99.8% carry an inspection year). Facility grain; native WGS84 Lat/Lon. Single-attribute source (ds_AST always true).

VA DEQ's Registered Petroleum Tank Facilities EDMA layer, filtered to FAC_ACTIVE_UST>0 AND FAC_RISK_RANK IS NOT NULL (5,630 facility rows) — mirrors the filter used by the Verified sibling va_deq__registered_ast_facilities exactly. Facility grain, not tank grain: this Integration's prediction (17,500±25%) was tank-scoped, but VA DEQ publishes no public tank-level feed. Sum of FAC_ACTIVE_UST across all facilities (17,659) confirms this is the correct dataset despite the facility/tank granularity mismatch.

Statewide registry of registered underground storage tank facilities, including facility, owner/operator, inspection and compliance-certification information.
