Relating to the time frame required for excavation notification.

HB 3791 updates Texas excavation notification rules to improve safety for underground utility lines. It requires excavators to notify utility centers 14 business days before digging (up from 3 days), with a 48-hour emergency option. The bill defines "Class A facilities" as critical infrastructure like gas lines, electrical systems, and telecom cables, mandating operators to mark their locations within 2 business days of notification. This directly affects construction crews, utility companies, and anyone planning underground work, aiming to reduce accidental damage to essential services.
