Landfill waste volume

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).
