Dear Ms. Smith:
This is in response to your recent letter requesting clarification of the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) applicable to transporting pumps and other
mechanical equipment contaminated with the residue of process chemicals, gases, and/or
byproducts. You state some of these residues meet the definition of a hazardous material
under the HMR. Specifically, you ask if hazardous material residue cannot be removed
from the equipment (e.g., without the use of special tools or without possibly rendering the
equipment unusable) can this residue be considered integral to the equipment when it is
offered for transportation in commerce.
The answer is yes. The HMR do not specifically define what is meant by hazardous
material residue that is integral to equipment. It is the opinion of this Office that hazardous
material residue in components of equipment or machinery may be considered integral if
the residue is necessary to the function of the equipment, its removal would cause damage
to the equipment, or it performs some other function necessary to the equipment such that it
cannot be removed from the equipment while it is in transportation. Please note that the
proper shipping names "Dangerous Goods in Machinery" and "Dangerous Goods in
Apparatus" are appropriate shipping names for components of machinery or equipment that
contain residual hazardous materials. Materials prepared for transportation using these
proper shipping names must comply with the requirements specified in § 173.222.
I hope this satisfies your request.
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division

Subject: Request for Interpretation of "Integral Element" of Machinery or Apparatus
Dear Mr. Foster,
RMS Interests, LLC is submitting a request for interpretation on behalf of a client who is seeking to fully comply with the
Department of Transportation's Hazardous Materials Regulations (HMR), 49 CFR § 171-180. This company does not have
the in-house expertise to clean or repair pumps and other parts used to support its manufacturing processes, and
therefore must offer these items for shipment to facilities which provide such services. This equipment contains residues
of process chemicals, gases, and byproducts, some of which are regulated by DOT as hazardous materials. In addition,
the pumps can weigh as much as 2,000 pounds each, so UN-approved packaging is not always available. Our client
wishes to determine the best method to represent the hazards and offer these items for safe transportation.
A search of the Pipeline and Hazardous Materials Safety Administration (PHMSA) letters of interpretation yielded
numerous packages characterized as "Dangerous Goods in Machinery or Apparatus" based on hazardous materials
which were required for the operation of the machine and therefore were clearly "integral elements" per special
provision 136. Letter #08-0146, dated June 25, 2008, appears to broaden the application of this shipping description
through the following statement: "Generally, items classified as Dangerous Goods in Apparatus (e.g., fuel pumps and
injectors, engines, parts, etc.) contain the residue of a hazardous material." May residues which were not present prior
to use, but exist now as process-related contaminants, be considered integral if they cannot be removed on-site
without using special tools or possibly rendering the machine unusable?
Our client plans to prepare the aforementioned pumps and parts for shipment as "Dangerous Goods in Machinery or
Apparatus"
, with the stipulation that they include the technical name of the primary hazardous material in the
description and meet special provisions 136 and A105, as well as any other requirements associated with the primary
hazardous material. If this interpretation is not acceptable, we would appreciate your guidance on how to proceed.
RMS Interests, LLC looks forward to receiving your response as soon as possible so that our client may continue
operating in full compliance with the agency's regulations. Please contact me at 512-619-3788 or
Robin@RMSInterests.com if you have any questions or need further information about this request. Thank you for your
assistance.
