SUPPLEMENTARY INFORMATION:
The pipeline safety regulations at 49 CFR 192.179 require that each point on an onshore gas pipeline in a Class 1 location must be within 10 miles of a sectionalizing block valve, unless in a particular case the RSPA Administrator finds that alternative spacing would provide an equivalent level of safety. This means that the distance between valves in a Class 1 location may not exceed 20 miles. During a recent review of its records, Tuscarora Gas Transmission Company (Tuscarora) discovered that during construction the upstream portions of its pipeline in Lassen County, California, were slightly re-routed to avoid a sensitive environmental habitat. As a result, the spacing between main line valves MLV-
( printed page 62517)
8 and MLV-9 exceeds the 20 mile maximum distance by 1,065 feet. Tuscarora requested a waiver of valve spacing requirement at § 192.179 for this line section.
In support of its waiver request, Tuscarora submitted the following:
The affected valve is located adjacent to an existing dirt roadway, providing ease of access.
All mainline block valves on the Tuscarora system are equipped with automatic line break detection and automatic closure devices.
The design, installation, and maintenance of the pipeline is in full compliance with49 CFR part 192.
The pipeline was constructed and placed in service in 1995 and is protected by an impressed current cathodic protection system.
The pipeline segment from MLV-8 to MLV-10 is designed, operated, and maintained to Class 1 requirements in accordance with49 CFR part 192.
Tuscarora's Gas Control Center continuously monitors conditions on the pipeline.
Operator response time to this area is less than one hour from the time of detection and notification.
Tuscarora's waiver request is available for review in the docket. RSPA/OPS is seeking comments on the waiver request. After the comment period has ended, RSPA/OPS will consider Tuscarora's waiver request and any public comments on the issues raised in its waiver request. RSPA/OPS' decision to grant or deny the waiver will be published in the
Federal Register.
