1. The performance of excavation work in the public right-of-way shall be in accordance with the applicable safety and construction codes. Nothing in sections 67.1830 to 67.1846 shall be construed as limiting the authority of the political subdivision to require public utility right-of-way users to comply with national safety codes and all other applicable zoning and safety ordinances, to the extent not inconsistent with public service commission laws or administrative rules.

2. Any contractor or subcontractor used for the performance of excavation work in the public right-of-way shall be properly licensed pursuant to the laws of the state and all applicable local ordinances if required, and each contractor or subcontractor shall have the same obligations with respect to its work as a public utility right-of-way user would have pursuant to sections 67.1830 to 67.1846 and applicable laws if the work were performed by the public utility. The public utility right-of-way user shall be responsible for ensuring that the work of contractors and subcontractors is performed consistent with its permits and applicable law and responsible for promptly correcting acts or omissions by any contractor or subcontractor.
