Tank truck carriers who perform significant cargo tank maintenance and repair in their own shops can expect a new Research and Special Programs Administration rule (HM-213) to impact their operations, says Cliff Harvison, National Tank Truck Carriers president.
"However, while this docket represents the most comprehensive rewrite of RSPA's cargo tank regulations in over a decade, it is important to note that the vast majority of the new rules will apply to cargo tank manufacturers and those who test, inspect, and repair specification equipment," Harvison says. "In other words, the impact on a carrier will vary. If all you do is run trucks, that impact will be minimal. If, however, you also do your own tank testing, inspections, repairs and modifications, the new requirements will be substantial."
The new rule, published in the "Federal Register" April 18, affects the construction and maintenance of cargo tank motor vehicles. It goes into effect October 1, 2003. RSPA is updating and clarifying regulations contained in 49 CFR Parts 107, 171, 172, 173, 177, 178, and 180. Voluntary compliance is authorized 30 days after the publication date.
Revisions applicable to DOT 400-series include structural integrity requirements, manhole marking, road clearance, maximum allowable working pressure (MAWP), leak testing using Environmental Protection Agency (EPA) Method 27, and weld joints on DOT407 cargo tanks.
Other revisions include those applicable to MC331 and MC338 cargo tanks, such as remote shutoffs, MC331 inlet and outlet fittings, visual inspections for insulated vessels, and leakage tests for tanks hauling anhydrous ammonia.
