Farm Road Springfield,IL 65802 Ref. No.: 10-0056 Dear Mr. Holden: This responds to your e-mail dated March 8, 2010 regarding the requirements for retest and inspection oflntermediate Bulk Containers (IBCs) under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if your understanding is correct that anyone who performs maintenance (e.g., cleaning or replacing the drum gaskets) on an IBC that has not been durably marked with the owner's state and name or authorized symbol, must durably mark the IBC every time routine maintenance is performed. The requirements for the routine maintenance for IBCs are found in § IS0.350(c). The routine maintenance of metal, rigid plastic, or composite IBCs, and plastics or textile flexible IBCs includes cleaning or replacing of body closures (including gaskets) or non-integral closures ties, as prescribed by § 180.350(c)(l)(i) and (ii) and § lS0.350(c)(2)(i) and (ii), respectively. The requirements applicable to routine maintenance of IBCs are further delineated in § 180.352(e). In accordance with this section, routine maintenance performed by a party other than the owner (whose state and name or authorized symbol is durably marked) must durably mark the IBC near the manufacturer's UN design type marking to show: (1) the country in which the maintenance was carried out; and (2) the name or authorized symbol ofthe party. Therefore, the cleaning or replacing of closures or gaskets on IBCs by parties other than the owner of the IBe must be durably marked on the IBC with the country and name or symbol of the party cleaning or doing routine maintenance on an IBe. I hope this information is helpful. If we can be of further assistance, please contact us. i";rt'~ Charles E.

My understanding of the section is that anyone who preforms routine maintenance(e.g. cleaning or replacing the drum gaskets)including the owner, (unless that have maked the IBC with their state and name), must durably mark the IBC evry time routine maintenance is preformed.
