RSPA proposal addresses some hazmat exemptions

The Research and Special Programs Administration (RSPA) is proposing to amend the hazardous material regulations (49 CFR, Parts 171, 173, 174, 176, 177) as part of an ongoing effort to identify commonly used exemptions that have an established history of safety, according to information published in the Federal Register December 4.

The proposed changes will eliminate the need for the current holders to reapply for extension of these exemptions every two years.

Among the changes are regulations applying to mechanical displacement meter provers, a mechanical device, permanently mounted on a truck or trailer, consisting of a piping system that is used to calibrate the accuracy and performance of meters that measure the quantity of product being pumped or transferred at facilities such as drilling locations, refineries, tank farms, and loading racks.

Exemptions provide relief from both bulk and non-bulk specification packaging requirements for mechanical displacement meter provers that are either truck or trailer mounted. The hazardous materials provided for are in Class 3 and Division 2.1. The exemptions affected are DOT-E 8278, 9004, 9048, 9162, 9287, 9305, 9352, 10228, 10596, 10765, 12047, and 12808.

The proposal also addresses exemptions that provide relief from the segregation requirements in Section 177.848 which prohibit storage, loading, and transportation of (1) cyanides, cyanide mixtures or solutions with acids; and (2) Division 4.2 materials with Class 8 liquids, on the same transport vehicle. The exemptions affected are DOT-E 9723, 9769, 10441, 10933, 11153, and 11294.
