#  Reporting and record retention requirements.

**AGENCY:**

Research and Special Programs Administration (RSPA), DOT.

**ACTION:**

Final rule.

**SUMMARY:**

This final rule corrects editorial errors, makes minor regulatory changes and, in response to requests for clarification, improves the clarity of certain provisions in the Hazardous Materials Regulations (HMR). The intended effect of this rule is to enhance the accuracy and reduce misunderstandings of the regulations. The amendments contained in this rule are minor changes and do not impose new requirements.

**DATES:**

*Effective date:* October 1, 2004.

**FOR FURTHER INFORMATION CONTACT:**

Darral Relerford, Office of Hazardous Materials Standards, (202) 366-8553, Research and Special Programs Administration, U.S. Department of Transportation, 400 Seventh Street, SW., Washington, DC 20590-0001.

**SUPPLEMENTARY INFORMATION:**

**I. Background**

The Research and Special Programs Administration (RSPA, we) annually  reviews the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180) to identify errors that may confuse readers. Inaccuracies corrected in this final rule include typographical and printing errors, incorrect references to regulations in the CFR, inconsistent use of terminology, and misstatements of certain regulatory requirements. In addition, we are making certain other changes to improve the clarity of certain HMR requirements.

Because these amendments do not impose new requirements, notice and public procedure are unnecessary. In addition, making these amendments effective without the customary 30-day delay following publication will allow the changes to appear in the next revision of 49 CFR.

The following is a section-by-section summary of the amendments made under this final rule. It does not discuss all minor editorial corrections (for example, punctuation errors) and certain other minor adjustments to enhance the clarity of the HMR.

**II. Section-by-Section Review**

**Part 106**

*Section 106.70.* In paragraph (b), in the first sentence, the wording “on you which are commenting” is revised to read “on which you are commenting.”

**Part 107**

*Section 107.219.* In paragraph (c), we are removing an obsolete reference to § 107.201(c).

*Appendix A to Subpart D of Part 107:* In Appendix A to subpart D of part 107, in the List of Frequently Cited Violations in Part II, under the heading “General Requirements” under “B. Training requirements:” entry 2. b., we are updating the Baseline assessment from “$250” to read “$275”. Also under the heading “Offeror Requirements—All hazardous materials,” under “D. Package Marking Requirements,” we are correcting the section reference “§ 172.303(a)(4)” to read “§ 172.304(a)(4)” in entry 8.

**Part 171**

*Section 171.6.* In paragraph (b)(2), the table of OMB control numbers is revised to reflect current affected sections for OMB Control Number 2137-0557.

**Part 172**

*Section 172.101 Hazardous Materials Table (HMT).* We are amending the HMT to correct certain entries, as follows:

—For the entry “Detonators, non-electric, *for blasting,* ” UN0455, in column (10A), the vessel stowage location code “5” is corrected to read “05.”

—For the entry “ *Etching acid, liquid, n.o.s., see* Hydrofluoric acid, solution *etc.,* ” in Column (2), the word “ *solution* ” is corrected from Roman type to italics.

—For the entry “Gasoline,” 3, UN1203, in column (7), Special Provision “B101” is corrected to read “B1.”

—For the entry “ *Methyl mercaptopropionaldehyde, see* Thia-4-pentanal,” in Column (2), the word “Thia-4-pentanal” is corrected to read “4-Thiapentanal.”

—For the entry “Perfumery Products, *with flammable solvents,* ” UN1266, Packing Group II, in column (9A), the quantity limitation for passenger aircraft/rail is corrected to read “15 L.” This error appears in Docket No. RSPA-2004-18575 (HM-189X) effective October 1, 2004 (July 13, 2004; 69 FR 41967).

—For the entry “Self-reactive liquid type F, UN3229,” Column (1) is revised by reinstating the letter “G,” which was inadvertently omitted in a recent rulemaking published on June 22, 2004, under Docket No. RSPA 2003-13658 (HM-215E), “Response to Appeals and Corrections,” (69 FR 34604).

—For the entry “Wood preservatives, UN1306,” the proper shipping name is corrected to read, “Wood preservatives, liquid.” This error appears in Docket No. RSPA-2004-18575 (HM-189X).

*Section 172.102.* In paragraph (c)(7)(vi)(D)(3), we are correcting the spelling of the word “not.”

*Section 172.202.* In paragraph (a)(2), we are correcting the reference to the section number for the Hazardous Materials Table. In paragraph (a)(2)(ii), we are correcting a proper shipping name by adding “n.o.s.” to “Combustible liquid.”

*Section 172.512.* In paragraphs (a)(3) and (b)(3), we are correcting section references.

**Part 173**

*Section 173.32.* In paragraph (c)(3), in the second sentence, we are correcting the reference “§ 178.275(f)(4)” to read “§ 178.275(f)(1).”

*Section 173.61.* In paragraph (c), we are correcting the ID number “NA 0350” to read “UN 0350.”

*Section 173.133.* Paragraphs (b)(1)(i) and (iii), in the formula, we are correcting “LC50 <sub>i</sub> ” to read “LC <sub>50i</sub> ” and “L <sub>C50i</sub> ” to read “LC <sub>50i</sub> .”

*Section 173.185.* Paragraphs (g)(2) and (j) are corrected to provide the correct section reference.

*Section 173.225.* In the Organic Peroxide Table, for the entry “tert-Butyl peroxyneodecanoate [as a stable dispersion in water],” UN3117, ≤52, under column (6), “Packing method” we are removing “, IBC” which is an error. Section 173.225(b)(6) states that the designation “IBC” means that Special Provision IB52 in the Hazardous Material Table in § 172.102 applies. Special Provision IB52 does not list “UN3117” as an authorized hazardous material for transport in an IBC. An IBC, however, may be authorized for this hazardous material when approved by the Associate Administrator as stated in § 172.102(c)(4).

*Section 173.315.* In paragraph (j)(3), in the last sentence, we are correcting the reference “§ 177.834(g)” to read “§ 177.834(a).”

*Section 173.316.* In paragraph (b), we are making a minor editorial revision and correcting the reference “§ 173.34(d)” to read “§ 173.301(f).”

**Part 178**

*Section 178.68.* In paragraph (i)(2), in the first sentence, we are correcting the reference “(i)(1)(i)” to read “(i)(1).”

*Section 178.276.* In paragraph (f), we are correcting the section reference “§ 178.275(h)” to read “§ 178.275(i).”

*Section 178.358-5.* In paragraph (c), we are correcting the parenthetical phase “(incorporated by reference; *see* § 171.1 of this subchapter)” to read “(IBR, see § 171.7 of this subchapter).”

*Section 178.609.* We are revising the wording in paragraphs (d)(1) and (2) to clarify test requirements for infectious substances packagings.

*Section 178.707.* In paragraph (c)(3)(iv), in the first sentence, we are correcting the wording “INCs” to read “IBCs.”

**Part 179**

*Section 179.200-16.* In paragraph (e), in the last sentence, we are correcting the section reference “§ 179.201-1(a)” to read “§ 179.201-1.”

*Section 179.220-17.* In paragraph (e), in the last sentence, we are correcting the section reference “§ 179.221-1(a)” to read “§ 179.221-1.”

*Section 179.300-1.* We are revising the section heading to remove an obsolete reference to § 179.302.

**Part 180**

*Section 180.403.* In the definition for “Replacement of a barrel,” we are correcting the section reference “§ 178.337-1” to read “§ 178.320.”

*Section 180.417.* Paragraph (b)(1)(v) is duplicative of the requirement in paragraph (b)(2)(v). Therefore, we are removing paragraph (b)(1)(v) and  redesignating paragraph (b)(2)(v) as paragraph (b)(1)(v). Paragraph (b)(2)(v) is being reserved.

**III. Rulemaking Analyses and Notices**

**A. Executive Order 12866 and DOT Regulatory Policies and Procedures**

This final rule is not considered a significant regulatory action under section 3(f) of Executive Order 12866 and, therefore, was not reviewed by the Office of Management and Budget. This rule is not significant under the Regulatory Policies and Procedures of the Department of Transportation (44 FR 11034). Because there is no economic impact of this rule, preparation of a regulatory impact analysis is not warranted.

**B. Executive Order 13132**

This final rule has been analyzed in accordance with the principles and criteria in Executive Order 13132 (“Federalism”). This final rule does not adopt any regulation that: (1) Has substantial direct effects on the States, the relationship between the national government and the States, or the distribution of power and responsibilities among the various levels of government; (2) imposes substantial direct compliance costs on State and local governments; or (3) preempts state law.

RSPA is not aware of any State, local, or Indian tribe requirements that would be preempted by correcting editorial errors and making minor regulatory changes. This final rule does not have sufficient federalism impacts to warrant the preparation of a federalism assessment.

**C. Executive Order 13175**

This rule has been analyzed in accordance with the principles and criteria contained in Executive Order 13175 (“Consultation and Coordination with Indian Tribal Governments”). Because this rule does not have tribal implications and does not impose substantial direct compliance costs, the funding and consultation requirements of Executive Order 13175 do not apply.

**D. Regulatory Flexibility Act**

I certify that this final rule will not have a significant economic impact on a substantial number of small entities. This rule makes minor regulatory changes which will not impose any new requirements on persons subject to the HMR; thus, there are no direct or indirect adverse economic impacts for small units of government, businesses or other organizations.

**E. Unfunded Mandates Reform Act of 1995**

This rule does not impose unfunded mandates under the Unfunded Mandates Reform Act of 1995. It does not result in costs of $120.7 million or more to either State, local, or tribal governments, in the aggregate, or to the private sector, and is the least burdensome alternative that achieves the objective of the rule.

**F. Paperwork Reduction Act**

There are no new information collection requirements in this final rule.

**G. Regulation Identifier Number (RIN)**

A regulation identifier number (RIN) is assigned to each regulatory action listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN number contained in the heading of this document can be used to cross-reference this action with the Unified Agenda.
