June 10, 1976
Mr. John Searcy
Tennessee Public Service Commission
Cordell Hull Building
Nashville, Tennessee 37219
Dear Mr. Searcy:
On May 6, 1976, we received a copy of the Commission's order in Docket No. U-6327 granting
38 natural gas distribution companies individual extensions of time to comply with the corrosion
control requirements of 49 CFR 192.457(b).
Under Section 3(e) of the Natural Gas Pipeline Safety Act of 1968, a State agency may not grant
a waiver from the Federal standards unless the Secretary is given at least 60 days' notice before
the effective date of the waiver. Accordingly, based on the date we received notice of the waiver,
it cannot become effective until July 6, 1976, unless we notify you before that date that we have
no objection to the waiver. We have assigned your letter Docket No. TN-76-1.
It would facilitate our review of this matter if you would send us a copy of (1) the petition filed by
the gas companies, (2) a description of each company's pipelines to which the waiver applies, and
(3) for each company, the reasons why the Commission found that an extension of time is
appropriate.
Sincerely,
Cesar DeLeon
Acting Director
Office of Pipeline
Safety Operations
