LUBBOCK, Texas (AP) — A decayed utility pole that broke, causing power wires to fall on dry grass in the Texas Panhandle, sparked the state’s largest wildfire in history, a Texas House committee confirmed Wednesday.

And other poorly maintained power equipment sparked four additional fires across the region earlier this year, the committee said.

The committee also found that a lack of readily available air support, ineffective communication from faulty equipment and coordination among agencies inhibited on-the-ground efforts to contain the Smokehouse Creek fire and others that ravaged the Panhandle earlier this year.

In response, the committee made up of three House members and two landowners recommended the Legislature have more effective monitoring and rule enforcement to check “irresponsible” oil and gas operators and improve accountability with utility providers when it comes to inspecting and replacing power poles.
