Modifies the "Underground Facility Safety and Damage Prevention Act"

HB 2329 updates Missouri's Underground Facility Safety and Damage Prevention Act by replacing existing definitions with new, more detailed terms to clarify responsibilities for underground utility owners and excavation operators. The bill specifically defines what constitutes an "underground facility," including pipes, cables, and wires for water, gas, electricity, and telecommunications, while also refining the scope of "excavation" to exclude routine maintenance and specific agricultural activities. It establishes standards for safety by referencing the Common Ground Alliance Best Practices, which guide how excavators should locate and mark underground lines before digging. Additionally, the legislation introduces modern concepts like "electronic white lining" and "locator strips" to improve the accuracy of locating buried infrastructure.
