SUBJECT: JURISDICTION OF PIPELINE SAFETY REGULATIONS AT REFINERIES

Purpose The purpose of this letter is to request your concurrence with Shell Oil Products Company"s (SOPC) interpretation regarding the limits of U.S. Department of Transportation and Louisiana DNR jurisdiction for pipelines leaving SOPC"c refinery at Norco, Louisiana.

Background SOPC operates a refinery at Norco, Louisiana. Subsequent to publication by RSPA of the "Regulatory Review - Hazardous Liquid and Carbon Dioxide Pipeline Safety Standards", in June, 1994, SOPC has reviewed the extent of regulatory jurisdiction of piping at this location.

Piping covered This letter covers piping through which products leave the refinery. The lines by this letter are operated and maintained by Shell Pipe Line Corporation outside the plant, and for a short distance inside the plant. Pressure is supplied by the refinery.

Regulations Hazardous Liquid Pipeline Safety regulations exclude from regulation "transportation of a hazardous liquid or carbon dioxide through . . . refining, or manufacturing facilities, or in-plant piping systems associated with such facilities".

The regulation also defines "in-plant piping system" to mean "piping that is located on the grounds of a plant and used to transfer hazardous liquid or carbon dioxide between plant facilities or between plant facilities and a pipeline or other mode of transportation, not including any device and associated piping that are necessary to control pressure in the pipeline under 195.406(b)."

SOPC"s SOPC interprets part 195 of the pipeline safety regulations to mean: interpretations

jurisdiction of pipeline safety regulations extend upstream, that is, into the refinery, to a device that is necessary to protect the pipeline outside the refinery from overpressure

the existence of additional overpressure protective devices within the plant, and for the protection of the piping between the pressure source and the device which protects the pipeline, does not affect the limits of jurisdiction, and a crossing of a single public thoroughfare by otherwise unregulated sections of in-plant piping does not affect the extent of jurisdiction.

Sketch attached A sketch of the piping under consideration is attached. This sketch does not represent any single piping system at the Norco refinery; rather, it combines elements of various systems.

Previous reviews The interpretations described in this letter were discussed in a February 20, 1995 meeting between Mike Chauvin and Shawn Hansson of SOPC, Dana Arabie of the Louisiana Department of Natural Resources, and Bill Bertges of the U.S. Department of Transportation. Bertges and Arabie recommended that these issues be directed to you in writing.

Questions If you have questions regarding this subject please call S.H. Hansson at (713) 241-1751.

Concurrence We request that you provide a written concurrence with SOPC"s interpretation requested of these regulations.

Yours very truly,

Joan Korpal

Manager Regulatory Compliance
