Environmental release severity

TCEQ Emergency Response Spills — the named Texas Open Data (Socrata) dataset xagr-a3x2 (spill notifications to the TCEQ Emergency Response Division, keyed by incident tracking number). 46,043 incidents, one row each. conform.py: ds_street from deliv_txt(+deliv_2_txt) with a phys_loc_desc_txt fallback, ds_city from near_city_name, ds_state constant 'TX', ds_zip from loc_zip_txt; ds_lat/lon from lat_dec_coord_num/long_dec_coord_num. Same reachable Socrata portal as tx_tceq__operating_dry_cleaner_registrations.

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.

VA DEQ EDMA ArcGIS layer 104, "Petroleum Releases (Daily)" — one row per release case (combined UST+AST), keyed on composite (RST_ID, PCNUM). Full historical archive since program inception (98.4% Closed cases). Distinct from the sibling va_deq registration sources (registered_ust_facilities/registered_ast_facilities are tank registrations, not releases) and from the general spill dataset (va_deq__prep_pollution_reports).
