Relating to work, an activity, or a function performed near a high voltage overhead line.

HB 3004 amends Texas law to clarify which court decisions can be appealed before final judgment. It adds 18 specific types of orders to the list of appealable interlocutory rulings, including motions related to electric utility liability (Section 1(13)), municipal lawsuits under local government codes (Section 1(14)), and summary judgments in cases involving overhead power lines. The bill does not change safety rules for workers near power lines; instead, it refines procedural rules for legal appeals. The "overhead line" definition added in Section 2 is a technical reference for these procedural changes, not a new safety standard. This is a procedural bill affecting court procedures, not direct policy for workers or utilities.
