Many of these places are places that tool already publishes, and the overlap is stated beside every figure here.","A row in this register is a permit event, not a building. One campus files a stormwater notice, an air authorisation and a separate notice for its electrical substation, and each is its own row. Records within 400 metres of one another are grouped into one place for that reason, and the number of records behind each place is published.","A construction stormwater notice means somebody told the state they were about to disturb ground. It does not prove a building exists, is finished, or is running, exactly as a building permit does not.","The active flag is the register's own and a blank is not the same as \"closed\". Both counts are given rather than filtering on it.","Most locations in this register are not addresses. The filer often describes where the site is, such as \"NW OF OMICRON DR & THETA DR\", so a place cannot always be tied to a parcel. Everything here is grouped and mapped by coordinate instead, and the number of narrative locations is published.","The county written on a filing is not reliable: one Amazon facility on Marbach Lane, which is in Bexar County, is filed under Comal. County here is derived from the coordinates instead.","Nothing in this register says how much electricity or water any of these places uses, how big it is, or what it cost. Those figures are not in this record and this page does not estimate them.","A facility is only here if somebody searched for its name. The names searched are published with their counts, including the zeroes, and an operator nobody thought of is invisible exactly as it is on the permit tool."],"source":{"name":"US EPA, Facility Registry Service (ECHO)","url":"https:\/\/echo.epa.gov\/","retrieved":"2026-08-29","note":"A facility is in this register because a state or federal environmental permit was filed for it, here mostly TCEQ construction stormwater notices and Clean Air Act authorisations."}}
