PHMSA letter of interpretation

Retaining Walls for Fuel Storage

Pipeline and Hazardous Materials Safety Administration · Oct 29, 1993 · Reference No. 93-0002

PHMSA says to use caution with this letter.

This is in response to your letter dated June 7, 1993, requesting information on specifications for building a retainer wall around a fuel storage area located at a water treatment plant. I apologize for the delay in responding and regret any inconvenience it may have caused.

I am not aware of any specification for building a retainer wall around a fuel storage area. I suggest that you contact the Environmental Protection Agency, 401 M Street, S.W., Washington, D.C. 20460, Telephone (202) 260-2342.

A letter of interpretation applies the regulations to the facts the requester described. It isn’t a regulation and isn’t legal advice. The agency’s copy.
