Dear Mr. Hendrickson:
This is in reply to your letter of February 25, 1971, concerning
interpretation of our leak reporting forms.
The type of damage which we require to be reported is determined
by our responsibility under the Natural Gas Pipeline Safety Act,
namely, the regulation of the transportation of gas in the
interest of safety. Therefore, we are not interested in
receiving information on incidents which result in damage to an
operator's equipment, where no gas leak is involved. We are
interested in receiving information on damage incurred where a
leak is present whether or not the damage results from the gas
leak, and whether or not the operator was reimbursed by the party
causing the damage. This damage would quite properly include the
loss of gas resulting from damage caused by others.
Since the document you enclosed was not official interpretation
by the Office of Pipeline Safety, the interpretation stated in
this letter, rather than that document, should be followed.
If we can be of further assistance to you, please let us know.
Sincerely,
Joseph C. Caldwell
Acting Director
Office of Pipeline Safety

February 25, 1971
Mr. Joseph C. Caldwell, Acting Director
Office of Pipeline Safety
800 Independence Avenue, S.W.
Washington, D.C. 20590
Dear Mr. Caldwell:
Please note underlined sections of the attached release from
the A.G.A. Operating Section.
Are not (1) and (2) contradictory? If you are interested in
the "overall amounts of money expended for repairs" why should
not the cost of repair of damages where no leak resulted also be
included? It seems to us rather incidental whether or not a leak
resulted from the damage as long as the damage was done and the
operator had the expense of repairing the same.
Also, in case of a loss of a large amount of gas, resulting
from such damage by others, would not the value of the gas lost
be part of the operator's cost?
We assume the operators total cost of repair s hould be
reported regardless of whether or not he was reimbursed for any
amount of this cost by the party causing such damage.
Very truly yours,
D. J. Hendrickson
Chief, Utility Safety Section
