What Texas Commission on Environmental Quali… offers
17 sourcesTCEQ 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.
TCEQ HB 2537 (1993) Closed & Abandoned UNNUMBERED Municipal Solid Waste Landfill Inventory = 2,772 old/closed unnumbered MSW landfills operated before permits were required, plus unauthorized landfills and illegal dumps — the HIST_LF attribute for TX. Single statewide Excel file (msw-unum-texas.xlsx) on the TCEQ MSW data page; NOT in any TCEQ GIS service or on data.texas.gov Socrata. Distinct from active permitted landfills (tx_tceq__active_landfills) and from closed NUMBERED/permitted facilities (msw-closed-facilities-texas.xls, not used — those had permits). Workbook row 1 is a provenance note; header is row 2 (fetch.py skips row 1). LOCATION (free-text locator) → ds_street 96.9%; LATIT_DD/LONGI_DD → ds_lat/lon 88.9% (309 rows carry a 0.0 null-island placeholder, blanked in conform, not fabricated); ds_state='TX' const; no city/zip cols. Fit (ds_street>90%). Count 2,772 ~6% under Tier-C predicted band (the '4,200' was the 1990s COG-located figure).
TCEQ Complaints — the named Texas Open Data (Socrata) dataset tdzs-qqjn (complaints received by TCEQ, tracked in the Consolidated Compliance and Enforcement Data System / CCEDS, keyed by complaint tracking number incid_track_num). 241,322 rows, full history. No street/city/state/ZIP/lat/lon fields exist in this dataset (only county and TCEQ region); ds_ address/location columns are all 0% fill, accepted by the developer since the COMPLAINTS attribute doesn't require location. ds_COMPLAINTS = true for every row.
TCEQ Operating Dry Cleaner Registrations — all currently-valid Texas dry-cleaning facility and drop-station registrations (Texas law requires both to register and renew annually). 1,331 active registrations (651 facilities + 680 drop stations) with registration id, entity/owner names, full location address, county, TCEQ region, solvent type/capacity, and a per-row coordinate point. Published as a Socrata Open Data dataset (qfph-9bnd) on data.texas.gov. Single-Attribute (DRYCLEANERS) source.
Statewide extract of engineering and institutional controls recorded across TCEQ remediation programs, assembled from Public Information Request 26-117411. The extract contains 871 control records at 583 sites and must be refreshed through a new public-information request.
TCEQ's ArcGIS 'Wastewater Outfalls' layer (Public/WW_oufalls/MapServer/0), publishing all TCEQ-permitted (and proposed-permit) TPDES/NPDES wastewater discharge outfall points statewide, with TCEQ-supplied decimal-degree coordinates. No street-level address fields are published (only COUNTY); ds_state is a constant "TX". 4,608 rows after conform.py's GIS_NUMBER dedup safeguard.
TCEQ Active Landfills from the public ArcGIS server (gisweb.tceq.texas.gov), service Landfills layer 0 'Active Landfills' = 193 currently-permitted MSW (Type 1) and C&D/other (Type 4) landfills statewide. Active-only: TCEQ publishes no statewide closed/historical landfill GIS layer (same as az_deq__landfills); matches the FY24 ~206 active-MSW figure. Single-attribute source (LF). Coordinates LATITUDE/LONGITUDE 100% (TX range); ADDRESS is a comma-delimited cell split deterministically (no libpostal) -> ds_street/city ~77%, ds_zip 75%, ds_state=TX. Fit (coordinates govern). Note: TCEQ MSD_Points/MSD_Polys are Municipal Setting Designations (groundwater program), NOT landfills.
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.
TCEQ public ArcGIS layer "LPST Points" — leaking petroleum storage tank incidents statewide (open + closed). One row per incident, keyed on LPST_ID (site-level RN can repeat across multiple incidents at the same site). ds_state hardcoded to TX per the tx_tceq__state_superfund precedent — layer has no explicit state column and is definitionally Texas-only.
Texas registered aboveground storage tanks from TCEQ's Petroleum Storage Tank (PST) program. Built from two PARIS fixed-width text extracts: the AST Extract (pst_ast.txt, one row per registered AST — tank status, regulatory status, capacity, substances stored) joined on FACILITY ID to the Facility Extract (pst_fac.txt) for the site address. 47,416 AST tanks across 20,877 facilities (IN USE + OUT OF USE); one conformed row per tank. TCEQ publishes no coordinates, so location is by street address only.
Texas registered underground storage tank (UST) registrations from TCEQ's Petroleum Storage Tank (PST) program PARIS extracts. Built from two fixed-width text extracts: the UST Extract (pst_ust.txt, one row per registered UST -- tank status, regulatory status, capacity, compartment count) joined on FACILITY ID to the Facility Extract (pst_fac.txt) for the site address. 189,652 UST tanks across 65,576 facilities (100% joined to a facility), active + historical. TCEQ publishes no coordinates, so location is by street address only.
Texas state Superfund (SF) sites — TCEQ-administered hazardous-substance sites addressed with state funds or via PRPs (the state CERCLIS-equivalent HWS universe per the Chubb Description). TCEQ public 'Superfund' MapServer layer 0 (REM_PROG uniformly 'Superfund (SF)'), the same reachable TCEQ ArcGIS host as the Verified tx_tceq__brownfields. 168 sites, fetched 2026-06-22. Coordinate-rich (100% lat/lon) but address-sparse (48.8% street — many are groundwater/area sites); rated Fit on coordinates per the better-of rule.

Public statewide ArcGIS inventory of sites in the TCEQ Brownfields Site Assessment program, including site identifiers, names, addresses, counties, regions, and coordinates.
Texas Voluntary Cleanup Program (VCP) site roster from the TCEQ public ArcGIS server (gisweb.tceq.texas.gov), service VCP layer 0 'Voluntary Cleanup' = 3,247 sites (REM_PROG='Voluntary Cleanup Program (VCP)'). State-native (provider tx_tceq, no divergence); same host/pattern as tx_tceq__brownfields / tx_tceq__state_superfund. Single-attribute (VCP). Coordinate-rich: ds_lat/lon 100% (LAT_DD/LONG_DD, TX range); ds_city 100%, ds_state=TX constant, ds_street 81.8% (PHYS_ADDR), ds_zip 81.7% -> Fit. Matches TCEQ's published ~3,300 cumulative VCP roster.
TCEQ's Dry Cleaner Remediation Program (DCRP) contamination site tracker -- combines the Priority List (249 sites, active/postponed) and Closed Sites list (121 sites), unioned by fetch.py, matching the Prediction Notes' cumulative DCRP methodology. 370 statewide sites. Distinct from the Verified tx_tceq__operating_dry_cleaner_registrations source, which lists operating businesses, not contamination sites.
TCEQ PARIS PST Facility Extract (pst_fac.txt), filtered to Number of Active USTs == 0 AND Number of Active ASTs == 0 — literal match to the Chubb Description ("no association as either underground or aboveground tanks"). One row per facility, keyed on FACILITY_ID (verified unique across all 84,230 unfiltered rows). Deliberately independent of the Verified tx_tceq__pst_ust/pst_ast sources — same PARIS program, different scope, no reuse. Below predicted band (51,232 vs 75,000-225,000) accepted as the cost of matching the Attribute's literal wording rather than the full unfiltered 84,230-row alternative.
Open Texas dataset and SODA API of TCEQ civil-enforcement judgments, including respondent identity and order date; server-side SoQL aggregation returns respondent-level judgment counts and latest judgment dates within this narrow enforcement scope.
