OH SB354

Modifies Ohio's "call before you dig" underground utility notification system by removing mandatory registration requirements for protection services and emphasizing single notification center approach

Expands definition of "public authority" to include designers acting on behalf of public entities, and redefines "protection service" to require registration by March 14, 1989, with Secretary of State and Public Utilities Commission

Adds new definitions for commercial excavators, positive response systems, tolerance zones (facility width plus 18 inches on each side), and emergency situations requiring immediate underground utility facility repair

Requires utilities to participate in protection services and utilize positive response systems; allows limited basis participation where utilities register only specific geographic areas; mandates protection services modify notification systems by July 1, 2013, to identify affected limited basis participants

Changes marking standards from "approximate location" to precise tolerance zones; adds requirements for utilities and excavators to use nondestructive excavation methods within tolerance zones; requires premarking of excavation sites before notification and changes slurry system color marking from blue to purple
