Dear Mr. Solanas:

Mr. Aubry has asked that we respond to your letter of August 13, 1981, requesting written validation of Mr. Orrs opinion that 49 CFR 192.179(d) gives operators the option of installing automatic or manual  shutoff valves.

We have considered the regulation at issue and its history set forth in Amendment 192-27 (41 FR 34606, August 16, 1976), and find that Mr. Orr’s view is correct since the rule does not and was not intended to specify the type of valve to be used.

Should you have any further questions, you may call me at 202-426-2392.
