No. 15-0179\nDear Mr. Storm:\nThis responds to your August 24, 2015 request for clarification pertaining to accumulators\nunder the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you\nask whether an accumulator in a \"hydraulic system used to maintain constant pressure, build\npressure gradually and store energy\" is eligible for the exception in § 173.306(f)(4) provided\nthe accumulators otherwise meet the requirements in § 173.306(f)(4)(i) to (iv) of the HMR.\nThe requirement in § 173.306(f)(4) applies to accumulators intended to function as shock\nabsorbers, struts, gas springs, pneumatic springs or other impact or energy-absorbing devices.\nBased on the information contained in your letter, the accumulators are not intended to\nfunction in any of these capacities and would therefore not be eligible for this exception.\nHowever, it should be noted that other exceptions for accumulators are provided in\n§ 173.306(f)(1), (2), (3), and (5).\nI hope this satisfies your request.\nSincerely,\nFAnn Faster\nT.
