Dear Ms. Hammond:

This is in response to your request for an interpretation of the federal jurisdiction over Illinois Power Company's (IPC) propane storage facility in Freeburg, Illinois. You request a determination of the applicability of 49 CFR §192.11 to the propane surge tank and the refrigerated storage sphere from which gas flows into the natural gas system for peak- shaving purposes.

All such "pipeline facilities" are within jurisdiction of the Natural Gas Pipeline Safety Act of 1968. A "pipeline facility" is defined in the Act to include “without limitation ... any equipment, facility, or building used in the transportation of gas or the treatment of gas during the course of transportation" (49 U.S.C. 1671(4)). In the regulations for gas pipelines, Section 192.11(a) states:

Each plant that supplies petroleum gas by pipeline to a natural gas distribution system must meet the requirements of this part and ANSI/NFPA 58 and 59.

Peak-shaving facilities are an interrelated and often essential part of a gas distribution system and fall within the intended coverage of the term "pipeline facilities." Consequently, a propane air peak-shaving facility is in its entirety subject to the jurisdiction of the Act.

If you have any questions regarding this matter, please contact Mike Israni at (202) 366-4571 or Buck Furrow at (202) 366-4559.

Sincerely,

Richard D. Huriaux, P.E.
