Dear Mr. Varga:
This is in response to your letter dated March 5, 1999,
concerning the definition of
"non-DOT specification portable
tanks suitable for the transport of liquids."
When the Hazardous Materials Regulations (HMR; 49 CFR Parts
171-180) authorize a "non-DOT specification portable tank
suitable for the transport of liquids" any portable tank, as
defined in S 171.8, may be used for the transportation of
liquids or solids as long as the portable tank meets the
general packaging requirements in SS 173.24 and 173.24b. " If
the HMR authorize its use, no exemption is required to use a
non-DOT specification portable tank. In addition, there are
no requirements in the HMR to identify a portable
tank as a
"non-DOT specification portable tank suitable for the
transport of liquids."
I hope this satisfies your request.
Sincerely,
Thomas
