Congress has directed the Secretary of Transportation to issue regulations that require each State to adopt or seek to adopt a one-call damage prevention program under State law as a condition to receiving a full grant-in-aid for the State's pipeline safety compliance program. The one-call damage prevention program must require that a one-call notification system cover each area of the State that contains underground pipeline facilities in accordance with minimum operational requirements. One-call notification systems, which are in existence throughout the country, are established to prevent excavation damage to underground pipelines and other utilities. They transfer information from excavators about intended excavation activities to the participating operators of underground pipelines and utilities, who then temporarily mark and identify their facilities. The state one-call damage prevention program must compel excavators to use the one-call notification systems and pipeline operators to participate in such systems under the threat of strong civil and criminal penalties for noncompliance. This notice invites interested persons to comment on the proposed regulations.
