Oklahoma Underground Facilities Damage Prevention Act; modifying certain definition. Effective date.

SB 355 updates definitions in Oklahoma's Underground Facilities Damage Prevention Act to clarify what constitutes "excavation." It specifically excludes routine agricultural work (like postholes or farm ponds), routine maintenance, and work on "certified" or "permitted" projects from the law's requirements. This affects contractors, utilities, and construction crews who must notify the Oklahoma One-Call System before digging. The bill makes the law's language clearer but does not change existing obligations for most excavation work.
