Hazardous Materials; Incorporation of Exemptions Into Regulations

AGENCY: Research and Special Programs Administration (RSPA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This final rule amends the Hazardous Materials Regulations by 
incorporating into the regulations the provisions of certain widely 
used exemptions which have established a history of safety and which 
may be converted into regulations for general use. We are also making 
minor revisions to the requirements for use of packagings authorized 
under exemptions. The revisions provide wider access to the benefits of 
the provisions granted in these exemptions and eliminate the need for 
the current exemption holders to reapply for renewal of the exemption, 
thus reducing paperwork burdens and facilitating commerce while 
maintaining an acceptable level of safety.

DATES: Effective Date: The effective date of these amendments is March 
25, 2005.
    Incorporation by Reference Date: The incorporation by reference of 
certain publications listed in these amendments is approved by the 
Director of the Federal Register as of March 25, 2005.
    Voluntary Compliance Date: RSPA is authorizing immediate voluntary 
compliance. However, RSPA may further revise this rule as a result of 
appeals it may receive for this rule.

SUPPLEMENTARY INFORMATION:

I. Background

    The Research and Special Programs Administration (RSPA) (hereafter, 
``we'' or ``us'') is amending the Hazardous Materials Regulations (HMR; 
49 CFR Parts 171-180) to incorporate a number of changes based on 
existing exemptions. This rulemaking is part of an ongoing effort to 
identify commonly used exemptions that have an established history of 
safety and may be converted into regulations. Adoption of these 
exemptions as rules of general applicability provides wider access to 
benefits of the provisions granted in these exemptions. Additionally, 
these changes eliminate the need for the current holders to reapply for 
extension of the exemptions every two years and for us to process these 
renewal requests. In addition, we are making minor revisions to the 
requirements for use of packagings authorized under exemptions. We have 
identified the following subjects as suitable for incorporation into 
the HMR in this final rule:
    Salvage cylinders: The use of non-DOT specification salvage 
cylinders for the overpacking and transportation in commerce of damaged 
or leaking cylinders of certain pressurized and non-pressurized 
hazardous materials has been authorized under various exemptions for 
several years. The exemptions affected are DOT-E 9507, 9781, 9991, 
10022, 10110, 10151, 10323, 10372, 10504, 10519, 10789, 10987, 11257, 
11459, 12698, 12790, and 12898. This final rule also responds to a 
petition for rulemaking (P-1168) submitted by the Chlorine Institute, 
Inc.
    Meter provers: A mechanical displacement meter prover is a 
mechanical device, permanently mounted on a truck or trailer, 
consisting of a piping system that is used to calibrate the accuracy 
and performance of meters that measure the quantity of product being 
pumped or transferred at facilities such as drilling locations, 
refineries, tank farms and loading racks. Exemptions provide relief 
from both bulk and non-bulk specification packaging requirements for 
mechanical displacement meter provers that are either truck or trailer 
mounted. The hazardous materials provided for are in Class 3 and 
Division 2.1. The exemptions affected are DOT-E 8278, 9004, 9048, 9162, 
9287, 9305, 9352, 10228, 10596, 10765, 12047, and 12808.
    Segregation: Exemptions provide relief from the segregation 
requirements in Sec. Sec.  174.81, 176.83 and 177.848 which prohibit 
storage, loading, and transportation of (1) cyanides, cyanide mixtures 
or solutions with acids; and (2) Division 4.2 materials with Class 8 
liquids, on the same transport vehicle. The exemptions affected are 
DOT-E 9723, 9769, 10441, 10933, 11153, and 11294.
    RSPA received six comments in response to the NPRM. These comments 
were submitted by representatives of trade organizations, hazardous 
materials shippers and carriers, and packaging

[[Page 3303]]

manufacturers. Most commenters expressed support for various proposals, 
but several raised concerns about certain provisions in the proposal 
that are discussed below.
    The following is a section-by-section summary of the changes, and 
where applicable, a discussion of comments received.

Section-by-Section Review

Part 171

Section 171.7

    We are incorporating by reference chapters II, III, IV, V and VI of 
the American Society of Mechanical Engineers (ASME) ``Pipeline 
Transportation Systems for Liquid Hydrocarbons and other Liquids,'' 
ASME B31.4-1998 Edition. See the Sec.  173.3 preamble discussion.
    We are also updating the entry for the Compressed Gas Association's 
Pamphlet C-6 to include a reference to Sec.  173.3.

Part 173

Section 173.3

    We are authorizing the use of salvage cylinders for overpacking a 
damaged or leaking cylinder containing hazardous materials other than 
Class 1 or 7 or acetylene. Salvage cylinders must be designed, 
constructed and marked in accordance with section VIII, division I of 
the ASME Code. Salvage cylinders are limited to a maximum capacity of 
450 L (119 gallons). Contents of the damaged cylinder must be limited 
in pressure and volume so that if the cylinder totally discharges into 
the salvage cylinder, the pressure in the salvage cylinder will not 
exceed the maximum allowable working pressure (MAWP). We have 
authorized the use of salvage cylinders under exemptions for several 
years with a safe and satisfactory transportation experience. Materials 
in Classes 1 and 7 and acetylene were not authorized under the terms of 
these exemptions; therefore, we have no transportation experience and 
are not including them in this final rule. Salvage cylinders must be 
retested in accordance with the Compressed Gas Association's (CGA) 
Pamphlet C-6; however, because a salvage cylinder is not a DOT 
specification cylinder, the requirement for a Requalification 
Identification Number (RIN) does not apply.
    In the NPRM, in paragraph (d)(2), we proposed that a ``salvage 
cylinder must have provisions for securely positioning the damaged 
cylinder therein.'' A commenter, Air Products, pointed out that not all 
cylinders have ``provisions'' for securing a damaged cylinder and asked 
RSPA to clarify what we meant. The intent of this requirement is to 
ensure that a damaged cylinder is secured in any manner that will 
prevent excessive motion during transportation; this could mean devices 
to secure the damaged cylinder or it could be compatible cushioning 
material that surrounds the damaged cylinder and restricts movement in 
the salvage cylinder. We revised the language in Sec.  173.3(d)(2) to 
reflect our intent.
    In the NPRM, we proposed that the contents of the damaged cylinder 
must be limited in pressure and volume so that if totally discharged 
into the salvage cylinder, the pressure in the salvage cylinder will 
not exceed the MAWP at 21 [deg]C (70 [deg]F) for non-liquefied gases, 
or 55 [deg]C (131 [deg]F) for liquefied gases. A commenter stated that 
under this proposal certain liquefied gases, such as carbon dioxide and 
nitrous oxide liquid, could not be transported in currently available 
salvage cylinders unless controls are employed to prevent the pressure 
from exceeding the MAWP. The commenter suggested that one way to 
control the pressure in a salvage cylinder would be refrigeration or, 
alternatively in the case of short distances in extremely hot 
environments, the use of a canopy to shade a salvage cylinder being 
transported on an open trailer. Under the exemption program, neither of 
these methods was authorized to prevent exceeding the MAWP. Instead of 
the pressure limits proposed in the NPRM, we amended paragraph (d)(4) 
to state that the contents of the damaged cylinder must be limited in 
pressure and volume so that if totally discharged into the salvage 
cylinder, the pressure in the salvage cylinder will not exceed 5/4 of 
the MAWP at 55 [deg]C (131 [deg]F). An exception to this is added for 
liquefied nitrous oxide and carbon dioxide cylinders. This is 
consistent with the general requirements for shipment of compressed 
gases in cylinders in Sec.  173.301.
    The same commenter requested that we allow placement of the 
requalification marking on a metal plate affixed to the pressure 
vessel. In the NPRM, in paragraph (d)(13), we proposed that each 
requalified cylinder ``must be durably and legibly marked on the 
sidewall * * * '', however, we did not specify how the marking would be 
applied to the cylinder. Based on the commenter's request, we 
reconsidered various means of marking the cylinder and revised (d)(13) 
to allow the requalification marking to be placed on any portion of the 
upper end of the cylinder or on a metal plate permanently secured to 
the cylinder. No stamping is authorized on the cylinder sidewall. This 
is consistent with the requalification markings in Sec.  180.213(b) and 
does not compromise the integrity of the cylinder.
    In the NPRM we proposed that a salvage cylinder must be visually 
inspected and pressure tested every two years. The Chlorine Institute 
pointed out that in Sec.  180.209 of the HMR we require cylinder 
requalification every five years for most cylinders. The commenter 
stated that a ``two year interval is unwarranted and would result in an 
increased burden to the industry.'' We agree with the commenter and are 
adopting a requalification frequency of five years.
    The Chlorine Institute also suggested that we should require all 
gaskets, valves and fittings be compatible with the hazardous materials 
overpacked in the salvage cylinder. We agree. Since all requirements 
for use of salvage cylinders are contained in Sec.  173.3(d), we are 
adding a new paragraph to include compatibility requirements for all 
gaskets, valves and fittings. We are also reformatting paragraph (d) 
for clarity.

Section 173.5a

    We are editorially revising the requirements in Sec.  173.5a and 
redesignating the current requirements as paragraph (a). We are also 
adding a new paragraph (b) to include provisions for the transportation 
of mechanical displacement meter provers. We have authorized the 
transportation of mechanical displacement meter provers under 
exemptions for several years with a safe and satisfactory 
transportation experience. A mechanical displacement meter prover is 
excepted from the specification packaging requirements when: (1) They 
have a capacity not over 1,000 gallons; (2) they are permanently 
mounted on a truck chassis or a trailer; and (3) they contain only the 
residue of a Class 3 or Division 2.1 material. A mechanical 
displacement meter prover must be designed and constructed in 
accordance with certain provisions specified in the ASME Standard 
B31.4, and is subject to periodic visual inspection and hydrostatic 
retesting. We did not receive any comments on this proposal and are 
adopting the amendment as proposed.

Section 173.12

    We are amending paragraph (b) to allow lab packs to also be 
transported for disposal and recovery by rail and cargo vessel. 
Currently, Sec.  173.12 authorizes the transportation of lab packs for 
disposal and recovery by highway only. However, under certain 
exemptions lab packs have been

[[Page 3304]]

authorized to be transported by rail and cargo vessel. Lab packs are 
combination packagings used for the transportation of waste materials 
in Class or Division 3, 4.1, 4.2, 4.3, 5.1, 6.1, 8 or 9. Lab packs are 
excepted from the specification packaging requirements for combination 
packagings if packaged in accordance with Sec.  173.12(b).
    We are adding a new paragraph (e) in Sec.  173.12 to authorize the 
transportation of waste cyanides and waste cyanide mixtures or 
solutions with acids under certain conditions. The HMR prohibit the 
loading, storage and transportation of cyanides and cyanide mixtures or 
solutions on the same transport vehicle with acids, if a mixture of the 
materials would generate hydrogen cyanide (see Sec. Sec.  174.81, 
176.83, and 177.848). Transportation of these materials on the same 
transport vehicle has been authorized under the terms of numerous 
exemptions with certain packaging and segregation requirements with a 
satisfactory and safe transportation experience. The exemptions 
affected are DOT-E 9723, 9769, 10441, and 10933. The NPRM proposed a 
maximum quantity limit of 1 kg for waste cyanides and waste cyanide 
mixtures and 1 L per inner receptacle for waste cyanide solutions. One 
commenter supported our proposal unconditionally. Another commenter, 
Onyx Environmental Services L.L.C., believes the ``quantity limits for 
inner packagings are overly restrictive'' and recommends that we allow 
up to 2 kg (4.4 lbs) or 2 L (0.6 gallon) net of cyanides per inner 
receptacle. The commenter pointed out that under a current exemption 
(DOT-E 13192) RSPA has allowed 2 kg per inner packaging. We agree with 
the commenter and are revising the quantity limits per inner packaging 
from 1 kg to 2 kg for solids and from 1 L to 2 L for liquids in this 
final rule.
    We are also authorizing the transportation of waste Division 4.2 
materials with Class 8 liquids under certain conditions. Storage, 
loading and transportation of Division 4.2 materials with Class 8 
liquids on the same transport vehicle or storage facility is prohibited 
by the HMR. However, we have authorized the transportation of these 
materials on the same transport vehicle under various exemptions and 
specified conditions with a safe and satisfactory transportation 
experience. The exemptions affected are DOT-E 11153 and 11294. In the 
NPRM we proposed a maximum quantity limit of 1 kg per inner packaging. 
Onyx Environmental Services L.L.C. requested that we allow 2 kg of 
Division 4.2 material instead of 1 kg for the exception in 
173.12(e)(2)(iii). We agree with the commenter and are allowing 2 kg 
per inner packaging for solids in this final rule.
    The same commenter requested we clarify that the quantity limits 
for inner packagings set forth in paragraph (e)(1) and (e)(2) are the 
net amounts of hazardous material, and not the gross weight of the 
package. We believe that the proposed language clearly indicates that 
quantity limits apply to the hazardous material in the inner packaging 
and not the completed package, and, therefore, are not amending this 
language.
    In the NPRM we proposed certain separation requirements. 
Specifically, we stated that the cyanide materials and the Division 4.2 
materials must be ``secured on pallets of not less than 100 mm (4 
inches) in height.'' A commenter suggested that in addition to 
securement on pallets, we allow the hazardous material to be otherwise 
elevated at least 100 mm (4 inches) off the floor of the freight 
container, unit load device, transport vehicle, or rail car. The 
commenter stated that this would allow shippers ``to load lab packs of 
cyanides on top of other packages (i.e., 55-gallon drums) that contain 
compatible materials in lieu of using a pallet.'' Since the intent of 
this requirement is to prevent commingling, we agree that means other 
than pallets that achieve this goal may be employed and are revising 
Sec.  173.12(e) accordingly. Readers are reminded that any package 
containing any hazardous material, not permanently attached to a motor 
vehicle, must be secured against movement, including relative motion 
between packages, within the vehicle on which it is being transported.

Section 173.13

    Section 173.13 excepts Class or Division 3, 4.1, 4.2, 4.3, 5.1, 
6.1, 8 or 9 materials from labeling and placarding requirements of the 
HMR if the material is packaged in accordance with the provisions of 
this section. The current exception applies to hazardous materials 
being transported by motor vehicle, rail car, or cargo aircraft. For 
transportation by cargo aircraft, the hazardous material must also be 
permitted to be transported on cargo aircraft in column (9B) of the 
Hazardous Materials Table (HMT). Section 173.13 restricts the net 
quantity per inner packaging to 1 L for liquids and 2.85 kg for solids 
and requires triple packaging which significantly exceeds the packaging 
standard currently authorized. For many years, we have also authorized 
transportation by passenger aircraft with certain limitations with a 
safe and satisfactory transportation experience. The affected 
exemptions are DOT E-7891, 8249, 9168, 10672, 10962, 10977, 11248, 
12177, 12230, and 12401. In the NPRM, we proposed to amend the HMR by 
expanding the exception to include transportation by passenger aircraft 
with certain limitations for materials that are permitted to be 
transported on passenger aircraft in column (9A) of the HMT. The 
exception provides a level of safety that is comparable to the level of 
safety previously provided under the exemption program.
    Two commenters (Federal Express and All-Pak) opposed the proposal 
to incorporate the provisions allowed under the exemption program into 
the regulations. The commenters expressed concern about the loss of 
controls that are provided under an exemption and believe that the 
packaging required under the exemption program is better than the 
packaging required by Sec.  173.13. FedEx goes on to say they ``believe 
this will significantly increase the chance for packaging failures.'' 
An exemption permits a person to perform a function that is not 
otherwise permitted under the HMR. RSPA believes that the safety record 
of the ``poison pack'' exemption packagings over the years has shown 
that they are safe and are acceptable for inclusion in the HMR. All-Pak 
states that their outer packaging is marked and certified as a PG I 
packaging, whereas Sec.  173.13 packagings are not. Both, FedEx and 
All-Pack, are under the impression that, as proposed in the NPRM, 
``outer packagings would not be marked with UN/ICAO packaging 
specification markings.'' We disagree. All Sec.  173.13 packagings are 
UN packages tested at the PG I level. Furthermore, a packaging that is 
represented as manufactured to a UN standard must be marked as 
specified in part 178.
    All-Pak questions whether RSPA has ``a sufficient track record upon 
which to base the proposed expansion of authority into passenger air 
traffic'' because they believe that there is little or no substantive 
experience with Sec.  173.13 packages. According to All-Pak, neither 
UPS nor FedEx allow packages prepared in accordance with Sec.  173.13 
on their aircraft. RSPA has knowledge that Sec.  173.13 packages are 
extensively used by leading life science and high technology chemical 
companies and are accepted by a number of carriers for both ground and 
air transportation. Because UPS and FedEx have made a business decision 
not to accept these packages, there may be less data concerning the 
performance of such packages than there would otherwise have been. 
Nevertheless, we believe

[[Page 3305]]

incorporation of these exemption provisions into the general regulation 
is appropriate based on the safe transportation of packages prepared in 
accordance with Sec.  173.13 by other modes of transportation, as well 
as on the safety record of the exemption program.
    FedEx stated that carrier personnel ``have long recognized and been 
trained to understand the exemption markings'' and that carriers who 
choose to accept packagings prepared in accordance with Sec.  173.13 
would be required to retrain their personnel. In a final rule published 
in the Federal Register May 30, 1996 (HM-222B; 61 FR 6480), RSPA 
amended the training requirements in subpart H to require that if a new 
regulation is adopted, or an existing regulation that pertains to a 
function performed by a hazmat employee is changed, the hazmat employee 
must be trained in the new or revised function-specific requirements 
without regard to the timing of the three year training cycle. The only 
instruction required is that necessary to assure knowledge of the new 
or revised regulatory requirement. It is not necessary to test the 
hazmat employee or retain records of the instruction provided in the 
new or revised requirements until the next scheduled retraining at or 
within the three year cycle.
    FedEx also asked RSPA to consider labeling packages prepared under 
exemptions DOT E-7891, 8249, 9168, 10672, 10962, 10977, 11248, 12177, 
12230, and 12401. This request is outside the scope of this rulemaking 
and is not addressed here.
    Another commenter requested we add clarifying language to indicate 
that packages prepared in accordance with Sec.  173.13 are not subject 
to the segregation requirements. While Sec.  177.848 clearly states 
that the segregation requirements apply to hazardous materials in 
packages which require hazard labels, parts 175 and 176 do not contain 
similar language. It is our intent to except from the segregation 
requirements those packages that are not required to be labeled in 
accordance with part 172 of the HMR. Therefore, we are revising 
paragraph (a) to include the exception from the segregation 
requirements.
    A commenter questioned why we allowed transportation of a hazardous 
material conforming to the requirements in Sec.  173.13(b) on a 
passenger vessel, but not on a cargo vessel. This was an error on our 
part. The first sentence in paragraph (b) should not have included the 
wording ``and passenger vessel.'' The preamble text in the NPRM 
reflects our intent to include transportation by passenger aircraft for 
packages prepared in accordance with this section. We did not intend or 
propose to include transportation by vessel and, therefore, in this 
final rule, are not authorizing transportation by vessel. 
Transportation by vessel may be considered in a future rulemaking.
    After publication of the NPRM, we found that we had overlooked 
quantity limits in column (9) of the HMT for a number of materials, 
both liquid and solid, which are lower than the quantity limits 
authorized in Sec.  173.13. To correct this oversight, in this final 
rule, we are limiting the net quantity in one package to the lesser of 
the amount specified in column (9) or the amount authorized in Sec.  
173.13 for materials transported by aircraft.
    For the reasons cited above, we are amending Sec.  173.13 of the 
HMR to include transportation by passenger aircraft with certain 
limitations for materials that are permitted to be transported on 
passenger aircraft in column (9A) of the HMT. The provisions in Sec.  
173.13 provide a level of safety that is comparable to the level of 
safety previously provided under the exemption program.

Section 173.22a

    We are revising paragraph (b) of Sec.  173.22a by removing the 
requirement that a copy of each exemption that authorizes use of a 
packaging must be maintained at each facility where the package is 
being used in connection with the transportation of a hazardous 
material. Currently, the ``Special Provisions'' section of each 
exemption states where the exemption must be maintained, if we believe 
it is necessary. We believe that such a requirement should be handled 
on a case-by-case basis and see no need for an across-the-board 
requirement in the HMR. This revision also responds to a petition for 
rulemaking (P-1293) submitted by W. W. Grainger, Inc. We are also 
revising paragraph (c) of Sec.  173.22a to clarify that a ``current'' 
copy of an exemption must be provided to the carrier by each person 
offering hazardous materials under the terms of an exemption when the 
exemption contains requirements that apply to the carrier. 
Additionally, we are adding the website address where a copy of an 
exemption can be obtained.

Part 174

Section 174.81

    We are revising paragraph (c) by adding a cross-reference to Sec.  
173.12(e) for cyanides, cyanide mixtures or solutions as well as 
Division 4.2 materials and, for clarity and consistency with Sec.  
177.848, amending the regulatory text. See Sec.  173.12 preamble 
discussion. We are also editorially revising paragraph (d) for clarity.

Part 176

Section 176.83

    We are adding a new paragraph (a)(11) to reference a segregation 
exception in Sec.  173.12(e) for lab packs containing cyanides and 
cyanide mixtures or solutions transported with acids, and for Division 
4.2 materials in lab packs transported with Class 8 liquids. See Sec.  
173.12 preamble discussion.

Section 176.84

    We are adding a footnote to paragraph (b), following Code ``52'' 
cross-referencing Sec.  173.12(e) for cyanides and cyanide mixtures or 
solutions in lab packs. See Sec.  173.12 preamble discussion.

Part 177

Section 177.848

    In the NPRM, we proposed to revise paragraph (c) by adding a cross-
reference to Sec.  173.12(e) for cyanides, cyanide mixtures or 
solutions as well as Division 4.2 materials. (See Sec.  173.12 preamble 
discussion.) A commenter requested that we clarify that the exception 
applies to cyanides, cyanide mixtures or solutions stored, loaded or 
transported with acids, and to Division 4.2 materials stored, loaded or 
transported with Class 8 liquids. We agree with the commenter and are 
amending the language in Sec.  173.12(e) accordingly. We are also 
editorially revising paragraph (d) for clarity.

II. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    1. 49 U.S.C. 5103(b) authorizes the Secretary of Transportation to 
prescribe regulations for the safe transportation, including security, 
of hazardous material in intrastate, interstate, and foreign commerce.
    2. 49 U.S.C. 5117(a) authorizes the Secretary of Transportation to 
issue an exemption from a regulation prescribed in 5103(b), 5104, 5110, 
or 5112 of the Federal Hazardous Materials Transportation Law to a 
person transporting, or causing to be transported, hazardous material 
in a way that achieves a safety level at least equal to the safety 
level required under the law, or consistent with the public interest, 
if a required safety level does not exist. In this rule, we are 
amending

[[Page 3306]]

regulations by converting certain widely used exemptions which have 
established a history of safety and which may, therefore, be converted 
into the regulations for general use.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This final rule is not considered a significant regulatory action 
under section 3(f) and was not reviewed by the Office of Management and 
Budget (OMB). This final rule is not considered a significant rule 
under the Regulatory Policies and Procedures order issued by the 
Department of Transportation [44 FR 11034]. The costs and benefits of 
this final rule are considered to be so minimal as to not warrant 
preparation of a regulatory impact analysis or a regulatory evaluation. 
The provisions of this final rule provide a relaxation of the 
regulations and, as such, impose little or no additional costs to 
affected industry.

C. Executive Order 13132

    This final rule was analyzed in accordance with the principles and 
criteria contained in Executive Order 13132 (``Federalism''). This 
final rule preempts State, local and Indian tribe requirements but does 
not impose any regulation that 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. Therefore, the consultation and funding 
requirements of Executive Order 13132 do not apply.
    Federal hazardous material transportation law, 49 U.S.C. 5101-5127, 
contains an express preemption provision (49 U.S.C. 5125(b)) preempting 
State, local, and Indian tribe requirements on certain covered 
subjects. Covered subjects are:
    (1) The designation, description, and classification of hazardous 
materials;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous materials;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous materials and requirements related to the number, 
contents, and placement of those documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous materials; or
    (5) The design, manufacture, fabrication, marking, maintenance, 
reconditioning, repair, or testing of a packaging or container 
represented, marked, certified, or sold as qualified for use in 
transporting hazardous material.
    This final rule concerns classification, packaging, marking, 
labeling, and handling of hazardous materials, among other covered 
subjects and preempts any State, local, or Indian tribe requirements 
concerning these subjects unless the non-Federal requirements are 
``substantively the same'' (see 49 CFR 107.202(d)) as the Federal 
requirements.
    Federal hazardous materials transportation law provides at 49 
U.S.C. 5125(b)(2) that if RSPA issues a regulation concerning any of 
the covered subjects, RSPA must determine and publish in the Federal 
Register the effective date of Federal preemption. The effective date 
may not be earlier than the 90th day following the date of issuance of 
the final rule and not later than two years after the date of issuance. 
The effective date of preemption is 90 days from the publication of 
this final rule in the Federal Register.

D. Executive Order 13175

    This final 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 final rule 
does not have tribal implications, does not impose substantial direct 
compliance costs on Indian tribal governments, and does not preempt 
tribal law, the funding and consultation requirements of Executive 
Order 13175 do not apply, and a tribal summary impact statement is not 
required.

E. Regulatory Flexibility Act, Executive Order 13272, and DOT 
Procedures and Policies

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
agency to review regulations to assess their impact on small entities. 
An agency must conduct a regulatory flexibility analysis unless it 
determines and certifies that a rule is not expected to have a 
significant impact on a substantial number of small entities. This 
final rule incorporates into the Hazardous Materials Regulations 
certain widely used exemptions. These amendments relax certain 
requirements, while maintaining safety. The amendments also result in 
modest cost savings and do not impose significant impacts on any of the 
entities, small or otherwise, potentially affected by the rule. 
Therefore, I certify this rule will not have a significant economic 
impact on a substantial number of small entities.
    This final rule has been developed in accordance with Executive 
Order 13272 (``Proper Consideration of Small Entities in Agency 
Rulemaking'') and DOT's procedures and policies to promote compliance 
with the Regulatory Flexibility Act to ensure that potential impacts of 
draft rules on small entities are properly considered.

F. Paperwork Reduction Act

    RSPA has current information collection approvals under: OMB No. 
2137-0051, ``Rulemaking, Exemption, and Preemption Requirements,'' with 
4,219 burden hours and an expiration date of May 31, 2006; and OMB No. 
2137-0022, ``Testing, Inspection, and Marking of Cylinders,'' with 
168,431 burden hours and an expiration date of September 30, 2005. We 
do not anticipate any significant change in burden of these current 
information collections as a result of this final rule.
    Section 1320.8(d), Title 5, Code of Federal Regulations requires 
that RSPA provide interested members of the public and affected 
agencies an opportunity to comment on information collection and 
recordkeeping requests. This notice identifies a new information 
collection request under OMB No. 2137-xxxx, ``Inspection and Testing of 
Meter Provers'' as proposed under this rule requiring annual visual 
inspections and 5-year pressure tests for meter provers. RSPA has 
submitted this new information collection request to the Office of 
Management and Budget (OMB) for approval based on the requirements in 
this final rule. This new information collection will be assigned an 
OMB control number after review and approval by OMB. We estimate that 
this new information collection burden will be as follows:
    OMB No. 2137-xxxx, ``Inspection and Testing of Meter Provers'':
    Annual Number of Respondents: 50.
    Annual Responses: 250.
    Annual Burden Hours: 175.
    Annual Burden Cost: $9,500.00.
    Requests for a copy of this information collection should be 
directed to Deborah Boothe or T. Glenn Foster, Office of Hazardous 
Materials Standards (DHM-10), Research and Special Programs 
Administration, Room 8430, 400 Seventh Street, SW., Washington, DC 
20590-0001, Telephone (202) 366-8553. We will publish a notice advising 
interested parties of the OMB control number for this information 
collection when assigned by OMB.

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

[[Page 3307]]

heading of this document can be used to cross-reference this action 
with the Unified Agenda.

H. Unfunded Mandates Reform Act

    This final 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.

I. Environmental Assessment

    The National Environmental Policy Act of 1969 (NEPA), as amended 
(42 U.S.C. 4321-4347), requires Federal agencies to consider the 
consequences of major Federal actions and prepare a detailed statement 
on actions significantly affecting the quality of the human 
environment. We developed an assessment to determine the effects of 
these revisions on the environment and whether a more comprehensive 
environmental impact statement may be required. We have concluded that 
there are no significant environmental impacts associated with this 
final rule. We received no comments concerning environmental impacts.

J. Privacy Act

    Anyone is able to search the electronic form of any written 
communications and comments received into any of our dockets by the 
name of the individual submitting the document (or signing the 
document, if submitted on behalf of an association, business, labor 
union, etc.). You may review DOT's complete Privacy Act Statement in

5. Section 173.5a is revised to read as follows:


Sec.  173.5a  Oilfield service vehicles and mechanical displacement 
meter provers.

    (a) Oilfield service vehicles. Notwithstanding Sec.  173.29 of this 
subchapter, a cargo tank motor vehicle used in oilfield servicing 
operations is not subject to the specification requirements of this 
subchapter provided--
    (1) The cargo tank and equipment contains only residual amounts 
(i.e., it is emptied so far as practicable) of a flammable liquid alone 
or in combination with water,
    (2) No flame producing device is operated during transportation, 
and
    (3) The proper shipping name is preceded by ``RESIDUE: LAST 
CONTAINED * * * '' on the shipping paper for each movement on a public

    (b) Mechanical displacement meter provers. (1) For purposes of this 
section, a mechanical displacement meter prover is a mechanical device, 
permanently mounted on a truck chassis or trailer and transported by 
motor vehicle, consisting of a pipe assembly that is used to calibrate 
the accuracy and performance of meters that measure the quantity of a 
product being pumped or transferred at facilities such as drilling 
locations, refineries, tank farms and loading racks.
    (2) A mechanical displacement meter prover is excepted from the 
specification packaging requirements in part 178 of this subchapter 
provided it--
    (i) Contains only the residue of a Class 3 or Division 2.1 
material. For liquids, the meter prover must be drained to the maximum 
extent practicable and may not exceed 10% of its capacity; for gases, 
the meter prover must not exceed 25% of the marked pressure rating;
    (ii) Has a water capacity of 3,785 L (1,000 gallons) or less;
    (iii) Is designed and constructed in accordance with chapters II, 
III, IV, V and VI of the ASME Standard B31.4 (IBR, see Sec.  171.7 of

the pipe component with the lowest pressure rating; and
    (v) Is equipped with rear-end protection as prescribed in Sec.  
178.337-10(c) of this subchapter and with 49 CFR 393.86 of the Federal 
Motor Carrier Safety Regulations.
    (3) The description on the shipping paper for a meter prover 
containing the residue of a hazardous material must include the phrase 
``RESIDUE: LAST CONTAINED * * * '' before the basic description.
    (4) Periodic test and inspection. (i) Each meter prover must be 
externally visually inspected once a year. The external visual 
inspection must include at a minimum: checking for leakage, defective 
fittings and welds, defective closures, significant dents and other 
defects or abnormalities which indicate a potential or actual weakness 
that could render the meter prover unsafe for transportation; and
    (ii) Each meter prover must be pressure tested once every 5 years 
at not less than 75% of design pressure. The pressure must be held for 
a period of time sufficiently long to assure detection of leaks, but in 
no case less than 5 minutes.
    (5) In addition to the training requirements in subpart H, the 
person who performs the visual inspection or pressure test and/or signs 
the inspection report must have the knowledge and ability to perform 
them as required by this section.
    (6) A meter prover that fails the periodic test and inspection, 
must be rejected and removed from hazardous materials service unless 
the meter prover is adequately repaired, and thereafter, a successful 
test is conducted in accordance with the requirements of this section.
    (7) Prior to any repair work, the meter prover must be emptied of 
any hazardous material. A meter prover

[[Page 3309]]

containing flammable lading must be purged.
    (8) Each meter prover successfully completing the external visual 
inspection and the pressure test must be marked with the test date 
(month/year), the type of test or inspection as follows:
    (i) V for external visual inspection; and
    (ii) P for pressure test.
    The marking must be on the side of a tank or the largest piping 
component in letters 32 mm (1.25 inches) high on a contrasting 
background.
    (9) The owner must retain a record of the most recent external 
visual inspection and pressure test until the next test or inspection 
of the same type successfully completed. The test or inspection report 
must include the following:
    (i) Serial number or other meter prover identifier;
    (ii) Type of test or inspection performed;
    (iii) Test date (month/year);
    (iv) Location of defects found, if any, and method used to repair 
each defect;
    (v) Name and address of person performing the test or inspection;
    (vi) Disposition statement, such as ``Meter Prover returned to 
service'' or ``Meter Prover removed from service''.
