ACRES

EPA's dedicated ACRES (Assessment, Cleanup and Redevelopment Exchange System) Brownfields properties layer, published via the FRS Geospatial Data Download service as the single-program ArcGIS FeatureServer `FRS_INTERESTS_ACRES` (same family as FRS_INTERESTS_AIR). Every record is a Brownfields property assessed or cleaned up with EPA Brownfields grant funding or via an EPA Regional Targeted Brownfields Assessment (PGM_SYS_ACRNM='ACRES', INTEREST_TYPE='BROWNFIELDS PROPERTY' on all rows). Distinct from and fuller than the Brownfields subset already carried by us_epa__cimc_sites, which per EPA's own documentation only includes grant-funded properties visible through the separate Cleanups in My Community tool. Fetched live: 44,235 properties nationwide, within the Integration's predicted 35,000-65,000 band. ds_street fill 99.94%, ds_lat/ds_lon fill 100% -- Fit rating.

CIMC Sites

EPA "Cleanups in My Community" (CIMC) national Sites FeatureServer — spans Superfund/NPL, RCRA Corrective Action, Brownfields, Federal Facilities, and OSC removals with per-program institutional/engineering-control indicators. Multi-attribute source: US_INST_CONTROL (Integration 190) and US_ENG_CONTROLS (Integration 189). Distinct from state-level INST_CONTROL sources (e.g. ny_dec__institutional_controls) — this is the national counterpart, no overlap. Composite PK (REGISTRY_ID, SF_SITE_ID, RCRA_HANDLER_ID, BF_PROPERTY_ID, EPAOSC_SITE_ID). Caveat: SF_IC_IND uses an undocumented numeric code domain (1/2/3/4), no published legend found; non-blank treated as "IC tracked" as the most defensible fallback, could overcount ds_US_INST_CONTROL by up to ~516 rows — see .md for detail.

PFAS Industry Sectors

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.
