Indiana Public Service Commission — Pipeline Safety Interpretation

Page 1March 25, 1971 Mr. D. J. Hendrickson Chief, Utility Safety Section Indiana Public Service Commission 901 State Office Building Indianapolis, Indiana 46204 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 dal\191\11\71-03-25 1#

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 dal\191\11\71-03-25 2#
