Mr. Loy McGee                     Ref. No: 01-0027
Harmon Tank Company, Inc.
P.O. Box 2068

Dear Mr. McGee:

This responds to your request for clarification of the periodic inspection and test requirements for non-specification cargo tanks authorized under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask about inspection and retest requirements for non­specification cargo tanks authorized to transport flammable liquid petroleum products in intrastate commerce.

As you note, § 173.8 of the HMR permits an intrastate motor carrier to transport flammable liquid petroleum products in a non-specification cargo tank having a capacity of 3,500 water gallons or less provided the conditions listed in paragraph (d) of § 173.8 are met. Beginning July 1,2000, such non-specification cargo tanks must conform to all periodic test and inspection requirements applicable to DOT specification MC 306 cargo tanks, except for those listed in § 180.405(g) (see § 173.8(d)(6)). The non-specification cargo tank need not be retrofitted to meet the MC 306 specification, but operators must adhere to the same inspection and testing schedule as outlined for an MC 306 specification cargo tank. The operator must complete only the inspections and tests applicable to the tank itself and the equipment and appurtenances installed on the tank. In the example you provide, a non-specification cargo tank that is not equipped with self-closing stop valves, remote closures, or similar emergency devices and valves is not required to meet the inspection and testing requirements applicable to such devices.

I hope this information is helpful. If you have any questions, please do not hesitate to contact this office.

Sincerely,
