Dear Mr. Blanton:
In your letter of May 28, 1999, you inquired about safety regulation jurisdiction over a natural gas pipeline operated by
the U. S. Gypsum Pipeline Company from Marion County, Tennessee, to Jackson County, Alabama. The pipeline
transports gas through a 10-inch diameter pipeline from an East Tennessee Natural Gas Company transmission line in
Tennessee to the U.S. Gypsum manufacturing facilities in Alabama. Of the total 15.4 miles of pipeline, 14 miles are in
Tennessee and 1.4 miles are in Alabama.
You asked us to review an opinion of our Southern Region that the Tennessee segment is under the jurisdiction of your
agency and the Alabama segment is under the jurisdiction of the Alabama Public Service Commission. We have
reviewed the applicable laws and regulations and discussed this matter with Frederick A. Joyner, Director of the
Southern Regional Office in Atlanta, GA. We now have additional information that a Certificate from the Federal
Energy Regulatory Commission (FERC) was issued authorizing the construction of this pipeline.
It is now clear that this pipeline is an interstate pipeline. It crosses a state line and is subject to the jurisdiction of FERC
as evidenced by that agency's issuance of an approval of the U.S. Gypsum Pipeline Company application under Section
7 of the Natural Gas Act. The U.S. Gypsum Pipeline Company line running from Tennessee to Alabama is subject to
the interstate regulatory jurisdiction of the Office of Pipeline Safety.
Southern Region has notified U.S. Gypsum that the pipeline is an interstate gas transmission line under the exclusive
safety regulatory jurisdiction of this agency.
If you need further assistance, please contact me or Fred Joyner at 404-562-3533.
Sincerely,
Richard B. Felder
Associate Administrator for Pipeline Safety
