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.

Eric Pfas Sites

FDEP's 'ERIC PFAS Sites' layer -- a pre-filtered cross-program extract of FDEP's master contaminated-site database (ERIC), scoped to sites where PFAS is the identified contaminant of concern, carrying a Rule 62-780 F.A.C. contamination classification field. 253 statewide sites across 7 FDEP cleanup programs. Note: the prediction was based on well/surface-water sampling-point populations, a different dataset type than this site-cleanup inventory; developer reviewed and accepted the resulting undercount.

HSCA Cleanup Activities

Pennsylvania DEP's public Hazardous Site Response Actions List is an annually refreshed SSRS CSV report derived from eFACTS and covering hazardous-site response work since 1988. The integrated product filters the report to HSCA initiations and emits 1,554 response-action × environmental-medium × substance rows across about 489 sites. It preserves facility identity, owner/operator, address, coordinates, Pennsylvania Priority List dates, response actions, media, and contaminant columns, while prepending normalized location fields and an HSCA indicator.

Manufactured Gas Plants

NY DEC's shared Environmental Remediation Sites Socrata dataset (c6ci-rzpg), filtered via a facility-name substring heuristic (MGP/MANUFACTURED GAS/GAS WORKS/GAS LIGHT) since DEC publishes no dedicated MGP dataset or program_type flag. 225 program-enrollment rows (HW 140/VCP 64/BCP 20/ERP 1) across 186 distinct physical MGP sites statewide; the raw undeduplicated count was chosen over the site-deduplicated count to avoid inventing a cross-program dedup key DEC doesn't provide.

Pcts Discharges

FDEP's statewide "Petroleum Contamination Monitoring (PCTS) Discharges from STCM" ArcGIS layer — the structured/queryable equivalent of FDEP's "Discharge Cleanup Summary" web report named in the Prediction Notes. Covers all storage-tank petroleum discharge/incident records tracked in the STCM database: 38,677 records as of 2026-07-13, across 27,800 distinct facilities. This layer is FDEP's full storage-tank contamination inventory — it is NOT exclusively scoped to underground tanks, and no FDEP field reliably distinguishes UST from AST discharges at the record level (ELIGIBILITY_PROGRAM is a funding-eligibility code, not a tank-type flag; FACILITY_TYPE doesn't cleanly split either, though ~92% of rows are UST-typical facility types like Retail Station and Fuel user/Non-retail). Fetched fully unfiltered; every row is marked ds_LUST=true per explicit developer confirmation, consistent with how the sibling ga_epd/de_dnrec/az_deq LUST Sources treat their state UST-cleanup registries as the LUST proxy. See the source .md for the full UST-vs-AST scoping discussion.
