Closed Landfill Inventory

Texas's statewide Excel file inventories old or closed unnumbered municipal solid-waste landfills that operated before permits were required, plus unauthorized landfills and illegal dumps. It reports identity, location, coordinates and accuracy, opening and closing dates, ownership, size and depth, final cover, waste indicators, update metadata, and source notes; its historical and location-precision limits must be preserved.

Open Dumps Line Listing

IHS publicly distributes a nationwide site-level open-dump snapshot for Indian lands with facility name and open-dump identifier, activity status, review status, physical/remediation condition, waste contents, land status, fencing, health-threat assessment, acreage, latitude/longitude, and last-edited date. A declared spatial comparison to a focal parcel directly answers officially inventoried dump presence and the regulator/program-recorded profile within this product's Indian-lands scope. Preserve workbook and retrieval vintage, raw status values, point grain, and the spatial method; do not infer permit, closure, post-closure, effective-date, contamination, compliance, parcel-identity, or no-site findings where the workbook does not report them.
