Approvals for Specification IM Portable Tanks

This is in response to your letter of August 1, 1997 concerning your proposed new certificate (provisionally entitled "Construction/Test certificate") and the issuance of an approval for Specification IM portable tanks under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).

Section 173.32a(b)(5)(ii) allows an approval agency to issue an approval for IM portable tanks successfully completing all requirements of the subpart. The approval agency must: (i) Apply its name, identifying mark or identifying number, and the date upon which the approval was issued, to the metal identification plate required by §178.270-14 of this subchapter; and (ii) Issue an approval certificate for each IM portable tank or, in the case of a series of identical tanks manufactured to a single design, for the series of IM portable tanks. The approval certificate must include all the information required to be displayed on the required metal identification plate. Your proposed new certificate meets these requirements.
