(a) This part contains the definitions for certain words and phrases used throughout this subchapter ( 49 CFR parts 105 through 110). At the beginning of each subpart, the Pipeline and Hazardous Materials Safety Administration (“PHMSA” or “we”) will identify the defined terms that are used within the subpart—by listing them—and refer the reader to the definitions in this part. This way, readers will know that PHMSA has given a term a precise meaning and will know where to look for it.

(b) Terms used in this part are defined as follows:

Approval means written consent, including a competent authority approval, from the Associate Administrator or other designated Department official, to perform a function that requires prior consent under subchapter C of this chapter ( 49 CFR parts 171 through 180).

Competent Authority means a national agency that is responsible, under its national law, for the control or regulation of some aspect of hazardous materials (dangerous goods) transportation. Another term for Competent Authority is “Appropriate authority” which is used in the International Civil Aviation Organization's (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air. The Associate Administrator is the United States Competent Authority for purposes of 49 CFR part 107.

Competent Authority Approval means an approval by the competent authority that is required under an international standard (for example, the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air and the International Maritime Dangerous Goods Code). Any of the following may be considered a competent authority approval if it satisfies the requirement of an international standard:

(1) A specific regulation in subchapter A or C of this chapter.

Federal hazardous material transportation law means 49 U.S.C. 5101 et seq.

File or Filed means received by the appropriate PHMSA or other designated office within the time specified in a regulation or rulemaking document.

Hazardous material means a substance or material that the Secretary of Transportation has determined is capable of posing an unreasonable risk to health, safety, and property when transported in commerce, and has designated as hazardous under section 5103 of Federal hazardous materials transportation law (49 U.S.C. 5103 ). The term includes hazardous substances, hazardous wastes, marine pollutants, elevated temperature materials, materials designated as hazardous in the Hazardous Materials Table (see 49 CFR 172.101 ), and materials that meet the defining criteria for hazard classes and divisions in part 173 of subchapter C of this chapter.

Hazardous Materials Regulations or HMR means the regulations at 49 CFR parts 171 through 180.

Indian tribe has the same meaning given that term in section 4 of the Indian Self-Determination and Education Assistance Act (25 U.S.C. 450b ).

Person means an individual, firm, copartnership, corporation, company, association, or joint-stock association (including any trustee, receiver, assignee, or similar representative); or a government or Indian tribe (or an agency or instrumentality of any government or Indian tribe) that transports a hazardous material to further a commercial enterprise or offers a hazardous material for transportation in commerce. Person does not include the following:

(1) The United States Postal Service.

(2) Any agency or instrumentality of the Federal government, for the purposes of 49 U.S.C. 5123 (civil penalties) and 5124 (criminal penalties).

(3) Any government or Indian tribe (or an agency or instrumentality of any government or Indian tribe) that transports hazardous material for a governmental purpose.

Regulations issued under Federal hazardous material transportation law include this subchapter A ( parts 105-110) and subchapter C ( parts 171-180) of this chapter, certain regulations in chapter I (United States Coast Guard) of title 46, Code of Federal Regulations, and in chapters III (Federal Motor Carrier Safety Administration) and XII (Transportation Security Administration) of subtitle B of this title, as indicated by the authority citations therein.

Special permit means a document issued by the Associate Administrator under the authority of 49 U.S.C. 5117 permitting a person to perform a function that is not otherwise permitted under subchapter A or C of this chapter, or other regulations issued under 49 U.S.C. 5101 et seq. (e.g., Federal Motor Carrier Safety routing requirements). The terms “special permit” and “exemption” have the same meaning for purposes of subchapter A or C of this chapter or other regulations issued under 49 U.S.C. 5101 through 5127. An exemption issued prior to October 1, 2005 remains valid until it is past its expiration date, terminated by the Associate Administrator, or is issued as a special permit, whichever occurs first.

State means a State of the United States, the District of Columbia, the Commonwealth of Puerto Rico, the Commonwealth of the Northern Mariana Islands, the Virgin Islands, American Samoa, Guam, or any other territory or possession of the United States designated by the Secretary.

Transports or Transportation means the movement of property and loading, unloading, or storage incidental to the movement.

Waiver of Preemption means a decision by the Associate Administrator to forego preemption of a non-Federal requirement—that is, to allow a State, political subdivision or Indian tribe requirement to remain in effect. The non-Federal requirement must provide at least as much public protection as the Federal hazardous materials transportation law and the regulations issued under Federal hazardous materials transportation law, and may not unreasonably burden commerce.
