Mr. E. L. Colvin, Vice President
Texas Eastern Transmission Corporation
P. O. Box 1612
Shreveport, LA 71130
Dear Mr. Colvin:
This is in response to your letter dated, August 7, 1973, with regard to protecting valves in your
transmission lines from public tampering pursuant to §192.179, 49 CFR.
We agree from your detailed explanation concerning the use of the "car" seal that the force
required to break the seal would have to be a strenuous effort by a strong and determined person.
From an examination of the "car" seal that you sent us, we agree that the "car" seal does offer a
sufficient deterrent to protect the valve from public tampering.
Thank you for assisting us in resolving this issue with regard to your transmission lines. By copy
of this letter we are informing the Kentucky Public Service Commission of our determination in
this matter.
Thank you for your continued cooperation.
Sincerely,
/signed/
Cesar DeLeon
Deputy Director
Office of Pipeline Safety
