What actually matters in this document.
Text
SUMMARY: RSPA is incorporating into the Hazardous Materials Regulations
(HMR) a number of changes, based on agency initiative, petitions for
rulemaking and comments received at public meetings, to the
classification of certain hazardous materials which are poisonous by
inhalation and to provisions for the manufacture, use and reuse of
hazardous materials packagings. These regulatory changes are intended
to improve safety, reduce compliance costs for offerors and
transporters of hazardous materials, make the regulations easier to
use, and correct errors.
DATES: Effective date. The effective date of these amendments is
January 1, 1997.
Compliance date. Because the amendments adopted herein generally
clarify and relax certain provisions scheduled to go into effect on
October 1, 1996, RSPA is authorizing immediate voluntary compliance.
However, persons voluntarily complying with these regulations should be
aware that petitions for reconsideration may be received and, as a
result of RSPA's evaluation of those petitions, the amendments adopted
in this final rule could be subject to further revision.
Incorporation by reference. The incorporation by reference of
certain publications listed in these amendments has been approved by
the Director of the Federal Register as of January 1, 1997.

SUPPLEMENTARY INFORMATION:
I. Background
On December 21, 1990, RSPA published a final rule [Docket HM-181;
55 FR 52402], which comprehensively revised the HMR with respect to
hazard communication, classification, and packaging requirements based
on the United Nations (UN) Recommendations on the Transport of
Dangerous Goods (UN Recommendations). A document responding to
petitions for reconsideration and containing editorial and substantive
revisions to the final rule was published on December 20, 1991 [56 FR
66124]. On October 1, 1992, under Dockets HM-181 and HM-189, RSPA
issued editorial and technical corrections to the regulations published
in 1991. On September 24, 1993, RSPA issued a final rule under Docket
HM-181F [58 FR 50224] which made changes to the HMR based on agency
initiative and petitions for rulemaking received since the December 20,
1991 response to petitions for reconsideration. That final rule
primarily revised requirements with a mandatory compliance date of
October 1, 1993, as provided in the transitional provisions in
Sec. 171.14(b)(4).
RSPA published a notice of proposed rulemaking (NPRM) on June 26,
1996, under Docket HM-181H [61 FR 33216] to address most remaining
issues associated with the implementation of Docket HM-181 provisions
and certain other issues arising from a final rule issued December 29,
1994, under Docket HM-215A [59 FR 67390]. These issues were raised
through petitions for rulemaking and agency initiative.
RSPA proposed changes to numerous requirements with a compliance
date of October 1, 1996. Although these changes focus primarily on
provisions concerning hazard classification and the maintenance and use
of performance packaging, RSPA also proposed changes to intermediate
bulk container (IBC) requirements, portable tank requirements, and
regulated medical waste provisions adopted under Dockets HM-181E and
HM-181G, respectively. Several current exemptions were proposed for
conversion into regulations of general applicability, and an approval
concerning design qualification and periodic testing was proposed for
incorporation into the HMR.
II. Summary of Comments to the NPRM
RSPA received nearly 40 comments in response to the proposed rule.
The comments were submitted by chemical manufacturing companies, trade
associations, packaging manufacturers, drum reconditioners, and various
organizations representing the medical waste industry. Commenters were
uniformly supportive of RSPA's efforts to address remaining issues
associated with Docket HM-181 and other issues arising from the Docket
HM-215A final rule. Certain issues proposed in the notice received
little or no comment. Other issues, such as drum reuse provisions,
display packs for ORM-D materials, an exception proposed for certain
Division 6.2 waste materials, and winter filling limits for tank cars,
were the focus of many of the comments. Several commenters requested
amendments to the HMR other than those proposed as part of this
initiative. Most of these suggestions are beyond the scope of the
proposed changes in this rule and are under review.
The Hazardous Materials Advisory Council (HMAC) expressed concern
that the proposed rule frequently cited a petition for rulemaking [P-
1169] without proposing adoption or discussing other provisions
identified by HMAC in their April 13, 1993 petition. HMAC also claimed
that another petition [P-1232], addressing outage requirements for
materials poisonous by inhalation, merited consideration because it
appeared to be within the scope of the Docket HM-181H rulemaking.
Petition P-1169 contained 25 separate issues that HMAC submitted to
RSPA for consideration to amend the HMR. Of the 25 issues identified in
that petition, RSPA has adopted a majority, including seven issues in
this rulemaking. The few remaining issues will appear in upcoming
proposed rulemaking actions (such as HM-215B) or are presently under
review.
Under Docket HM-181, RSPA adopted a five percent outage requirement
for poisonous by inhalation hazard materials in bulk packagings.
Chemical manufacturers and associations, such as HMAC, opposed this
requirement, claiming that any safety benefit is offset by additional
shipments and resultant costs. RSPA believes a change in outage
requirements is beyond the scope of this rulemaking.
III. Summary of Regulatory Changes by Section
Listed below is a section-by-section summary of changes and, as
applicable, a discussion of comments received.
Part 171
Section 171.7. The table of material incorporated by reference is
amended by adding a new entry referencing a publication issued by the
Department of Health and Human Services for defining biosafety levels
and adding two new ASTM steel standards referenced in Sec. 178.601.
Section 171.14. All transitional provisions reflecting a compliance
date of October 1, 1996, or earlier are
[[Page 50617]]
removed. One commenter representing the agricultural chemical industry
asked RSPA to establish a five-year delayed compliance date for
products in DOT specification and non-specification packagings filled
before October 1, 1996. The commenter described a lengthy process for
agricultural chemicals moving through a distribution chain to end users
and then frequent product returns several years after the original
sale. According to the commenter, an additional five-year compliance
period would provide sufficient time for the industry to eliminate any
non- specification and DOT-specification packagings which would not
otherwise be authorized after October 1, 1996.
RSPA provided a five-year transition period from October 1, 1991 to
October 1, 1996 for users of these packagings to deplete inventory and
phase in UN performance packagings. RSPA believes this five-year
transition period has afforded industry sufficient time to prepare for
the October 1, 1996 compliance date. However, RSPA recognizes that an
extensive distribution process that includes procedures for return of
products to distributors warrants limited relief to allow the
transportation of materials in previously authorized and filled
packages to end users or for their return, repackaging, or disposal.
From an overall transportation safety perspective, it is RSPA's view
that it is safer to allow one final shipment of these previously
authorized and filled packagings than to compel the transfer of
materials, such as pesticides, into packagings required by the HMR as
of October 1, 1996.
Therefore, RSPA is adding a provision to authorize non-bulk
packagings, other than cylinders, which were filled prior to October 1,
1996 in conformance with regulations in effect on September 30, 1996,
to be offered for transportation and transported domestically until
October 1, 1999. RSPA believes a three-year delay in compliance affords
sufficient time for these packagings to be eliminated from a
distribution system. It is emphasized that this provision does not
authorize the filling of packagings, only offering and transportation
of packagings filled prior to October 1, 1996.
In addition, three other transition provisions are retained for
packages filled prior to October 1, 1991, new placard specifications,
and authorization for use of fiber drums.
Part 172
Section 172.101. The text preceding the Sec. 172.101 Hazardous
Materials Table (HMT) sets forth procedures for using the HMT. To
clarify procedures contained in paragraph (c)(12)(iii) for selecting a
proper shipping name for a material that meets the definition of more
than one hazard class, RSPA proposed to replace the phrase ``identified
* * * by a specific description'' with ``identified * * * specifically
by name'' and include an example. All three commenters addressing this
issue supported this proposed change, stating that it will clarify the
procedure for selecting a proper shipping name.
In addition, RSPA is adding as proposed a new paragraph
(c)(10)(iii) which clarifies the process for selecting a proper
shipping name for a mixture of two or more hazardous materials in the
same hazard class. Currently, paragraph (c)(10)(i) contains a provision
for selecting a proper shipping name for a mixture of a hazardous
material and non-hazardous material, and paragraph (c)(12)(ii)
prescribes the proper shipping name selection process for a material
meeting more than one hazard class.
Section 172.101; the Hazardous Materials Table (HMT). A new entry
to provide for the domestic transportation of black powder for small
arms reclassed as a Division 4.1 is added as proposed. This revision is
based on comparable provisions for smokeless powder, small arms
cartridges and power device cartridges. In conjunction with this
change, a new Special Provision 70 and new non-bulk packaging section
Sec. 173.170 is added.
In the HMT, the entries ``Chlorosilanes, n.o.s.'', with
identification numbers UN 2986, UN 2987, and UN 2988, are not
authorized to be shipped in DOT Specification Intermodal (IM) portable
tanks. Based on a petition for rulemaking requesting that RSPA
authorize IM portable tanks for all chlorosilanes and that the use of
IM portable tanks for these materials will not compromise safety and
would be consistent with other specific authorizations, RSPA is
adopting the proposal to authorize certain IM portable tanks for all
chlorosilanes. RSPA is adding special provisions in Column (7) for
``Chlorosilanes, n.o.s.'', with identification numbers UN 2986, UN
2987, and UN 2988, to permit the transport of these materials in IM
portable tanks.
Bulk packaging references for three Type F organic peroxides (UN
3110, UN 3119, and UN 3120) are revised by changing ``None'' to ``225''
in Column (8C) to indicate that these materials are authorized in bulk
packagings. In addition, for the entries ``Organic Peroxide, type F,
liquid (or solid), temperature controlled'' (UN 3119 and UN 3120), in
Column (8A), the packaging exception reference ``152'' is removed for
each entry to indicate that these temperature controlled organic
peroxides are not eligible for packaging exceptions. One commenter
noted that even though Sec. 173.225 is authorized in Column (8C) of the
Hazardous Materials Table, this authorization alone will not allow bulk
packaging for organic peroxide, type F, solid. A note in Column 8 of
the Organic Peroxide Table, in conjunction with the technical name of
the material, indicates whether the material is authorized to be
packaged in a bulk packaging.
More than 30 entries classed as Division 4.3 (dangerous when wet)
solids in Packing Groups II and III are amended by revising Column (8A)
to authorize Sec. 173.151 as a packaging exception section. One
commenter asked RSPA to authorize a packaging exception section for
three additional Division 4.3 materials that exhibit similar
characteristics and do not pose an unreasonable risk in transportation.
After reviewing these materials, RSPA agrees and is adding them to the
list of entries that are authorized a packaging exception in
Sec. 173.151.
Revisions to Classification and Hazard Zone Identification for
Certain Materials Poisonous by Inhalation. Based on acute inhalation
toxicity data and related information obtained by RSPA, the HMT is
amended to change the hazard zone for some materials poisonous by
inhalation, and to add other materials to the list of materials
poisonous by inhalation. For certain materials this revision imposes
more stringent hazard communication and packaging requirements. The
Docket HM-181H NPRM contains a more complete description of the data on
which these revisions are based. The materials are listed as follows:
a. Hydrogen cyanide, solution in alcohol (with not more than 45
percent hydrogen cyanide) (UN3294). Based on the toxicity and
volatility of hydrogen cyanide, the packing group assigned and the
dilution factor for this solution of hydrogen cyanide, RSPA is
identifying hydrogen cyanide, solution in alcohol with not more than 45
percent hydrogen cyanide as a Hazard Zone B inhalation hazard. A new
special provision ``25'' is assigned to this entry to authorize a one-
year delay for compliance with new packaging requirements.
b. Metal carbonyls, n.o.s. (UN3281). The acute toxicity of metal
carbonyls may differ from one compound to another. Those toxic by
inhalation may fall into Hazard Zone A or Hazard Zone B. Others may not
be toxic by inhalation, but may exhibit oral and/or dermal toxicity,
which places them in
[[Page 50618]]
Division 6.1, Packing Group I. Therefore, RSPA is adding special
provision ``5'' to Column 7 of the entry for metal carbonyls, n.o.s. at
the Packing Group I level.
c. Methanesulfonyl chloride (UN3246). As proposed, RSPA is
identifying methanesulfonyl chloride as a Hazard Zone B inhalation
hazard. A new special provision ``25'' is assigned to this entry to
authorize a one-year delay for compliance with new packaging
requirements.
d. Methyl vinyl ketone (UN1251). As proposed, RSPA is identifying
methyl vinyl ketone as a Hazard Zone A inhalation hazard. Also, to be
consistent with the UN Recommendations (Eighth revised edition), RSPA
is adding the plus (+) symbol to Column 1 of the entry for methyl vinyl
ketone. A new special provision ``25'' is assigned to this entry to
authorize a one-year delay for compliance with new packaging
requirements.
e. Nitriles, toxic, flammable, n.o.s. (UN3275). This generic entry
covers Division 6.1, Packing Groups I and II toxic, flammable nitriles
that are not specifically listed by name but exhibit acute oral, dermal
and/or inhalation toxicity. The acute toxicity of these nitriles may
differ from one compound to another. Those toxic by inhalation may fall
into Hazard Zone A or Hazard Zone B. Other nitriles may not be toxic by
inhalation, but may exhibit oral and/or dermal toxicity which places
them in Division 6.1, Packing Group I. Therefore, RSPA is adding
special provision ``5'' to Column 7 of the entry for nitriles, toxic,
flammable, n.o.s. at the Packing Group I level.
f. Nitriles, toxic, n.o.s. (UN3276). This generic entry covers
Division 6.1, Packing Groups I, II and III toxic nitriles that are not
specifically listed by name but exhibit acute oral, dermal and/or
inhalation toxicity. The acute toxicity of these nitriles may differ
from one compound to another. Those toxic by inhalation may fall into
Hazard Zone A or Hazard Zone B. Other nitriles may not be toxic by
inhalation, but may exhibit oral and/or dermal toxicity which places
them in Division 6.1, Packing Group I. Therefore, RSPA is adding
special provision ``5'' to Column 7 of the entry for nitriles, toxic,
n.o.s. at the Packing Group I level.
g. Organoarsenic compound, n.o.s. (UN3280). This generic entry
covers Division 6.1, Packing Groups I, II and III toxic organoarsenic
compounds that are not specifically listed by name but exhibit acute
oral, dermal and/or inhalation toxicity. The acute toxicity of these
organoarsenic compounds may differ from one compound to another. Those
toxic by inhalation may fall into Hazard Zone A or Hazard Zone B.
Others may not be toxic by inhalation, but may exhibit oral and/or
dermal toxicity which places them in Division 6.1, Packing Group I.
Therefore, RSPA is adding special provision ``5'' to Column 7 of the
entry for organoarsenic compound, n.o.s. at the Packing Group I level.
h. Organophosphorus compound, toxic, flammable, n.o.s. (UN3279).
This generic entry covers Division 6.1, Packing Groups I and II toxic,
flammable organophosphorus compounds that are not specifically listed
by name but may exhibit acute oral, dermal and/or inhalation toxicity.
The acute toxicity of these organophosphorus compounds may differ from
one compound to another. Those toxic by inhalation may fall into Hazard
Zone A or Hazard Zone B. Others may not be toxic by inhalation, but may
exhibit oral and/or dermal toxicity which places them in Division 6.1,
Packing Group I. Therefore, RSPA is adding special provision ``5'' to
Column 7 of the entry for organophosphorus compound, toxic, flammable,
n.o.s. at the Packing Group I level.
i. Organophosphorus compound, toxic, n.o.s. (UN3278). This generic
entry covers Division 6.1, Packing Groups I, II and III toxic
organophosphorus compounds that are not listed by name but exhibit
acute oral, dermal and/or inhalation toxicity. The acute toxicity of
these organophosphorus compounds may differ from one compound to
another. Those toxic by inhalation may fall into Hazard Zone A or
Hazard Zone B. Others may not be toxic by inhalation, but may exhibit
oral and/or dermal toxicity which places them in Packing Group I.
Therefore, RSPA is adding special provision ``5'' to Column 7 of this
entry for organophosphorus compound, toxic, n.o.s. at the Packing Group
I level.
j. Phosphorus pentafluoride (UN2198). As proposed, RSPA is
identifying phosphorus pentafluoride as a Hazard Zone B inhalation
hazard.
k. Tungsten hexafluoride (UN2196). As proposed, RSPA is identifying
tungsten hexafluoride as a Hazard Zone B inhalation hazard.
Section 172.102. As noted in the discussion on revisions for
materials poisonous by inhalation, RSPA is authorizing a one-year delay
for compliance with new packaging requirements by assigning a new
special provision ``25'' to three commodities.
Special Provision B59, which authorizes AAR 207A tank cars for
phosphorus pentasulfide, is revised as proposed to reference the use of
water-tight, sift-proof, closed-top, metal-covered hopper cars.
A new special provision (N42) is added as proposed to authorize a
UN 1A1 steel drum for stabilized benzyl chloride. One comment was
received in response to this proposal and strongly supported the
addition of N42, which allows use of phenolic-lined steel drums with a
minimum thickness of 1.3 mm (0.050 inch) which have been tested and
certified to a Packing Group I level at a specific gravity of 1.8. The
commenter cited a history of shipping benzyl chloride in phenolic-lined
17C and UN 1A1 steel drums since 1981 without incident and without
failure of the phenolic lining.
Section 172.302. In the general marking requirements for bulk
packagings, markings on portable tanks with capacities of less than
3,785 L (1,000 gallons) must be at least 6.0 mm (0.24 inch) wide and at
least 25 mm (one inch) high. RSPA proposed a revision of paragraph
(b)(2) to decrease to 4 mm (0.16 inch) the minimum width of markings
required on portable tanks having a capacity less than 3,785 L (1,000
gallons). RSPA also proposed reducing both the minimum height and width
of markings required on IBCs to 25 mm (one inch). Commenters were
uniformly supportive of both proposals, and they are adopted as
proposed. RSPA is not adopting one commenter's recommendation to amend
Appendix B to Subpart B of Part 107 to allow a marking height of one
inch for certain small portable tanks authorized under an exemption.
Section 172.504. RSPA is removing the second sentence of paragraph
(f)(8) which allows a CLASS 9 placard to be substituted for a
COMBUSTIBLE LIQUID placard for material meeting both Combustible liquid
and Class 9 hazard classes. Several commenters agreed that this
provision created potential confusion and misunderstanding between
documentation and marking requirements describing a Combustible liquid
and the application of CLASS 9 placards.
Part 173
Section 173.24a. RSPA proposed to amend paragraph (a)(3) to clarify
that cushioning material used to protect inner packagings must not be
adversely affected (e.g., disintegrate) if there is leakage of a
hazardous material from the inner packagings. A degradation of
cushioning materials could significantly reduce the effectiveness of a
packaging to a point that it would not conform with its marked
performance standard
[[Page 50619]]
or meet general packaging requirements. This clarification is
consistent with international air transport provisions contained in the
International Civil Aviation Organization's (ICAO) Technical
Instructions. Commenters supported this proposed revision; however, the
Fibre Box Association expressed concern that the proposal might be
interpreted to mean corrugated cushioning and corrugated packaging of
liquids will not be allowed. The Fibre Box Association stated that the
phrase ``having protective properties [significantly] impaired in event
of leakage'' is too vague.
The proposed change was not intended to preclude the use of
fiberboard cushioning or packaging for liquids. Although there is no
established criteria for evaluating degradation of cushioning material,
RSPA agrees that the phrase ``significantly impaired'' should be
revised. RSPA believes ``significantly weakened'' more accurately
conveys the intent of this provision and is revising this phrase
accordingly.
Currently, paragraphs (b)(1) and (b)(2) provide filling limits for
single and composite packagings, but no such limits are provided for
combination packagings. As proposed, RSPA is revising paragraph (b)(2)
of this section to prescribe filling limits for all non-bulk
packagings, including combination packagings. This provision prohibits
combination packagings from being filled with a hazardous material to a
gross mass greater than the maximum gross mass marked on the packaging.
Section 173.28. RSPA proposed adding a formula in paragraph (b)(4)
for calculating an equivalent minimum thickness for stainless steel
drums. This formula is consistent with the formula contained in
Sec. 178.705 for calculating minimum wall thicknesses for metal IBCs.
The Association of Container Reconditioners (ACR) opposed this proposed
change and stated that this issue is too complex for adoption at this
time. ACR believes that by reducing the minimum thickness of stainless
steel to the equivalent strength of carbon steel, the rationale for
waiving leakproofness testing for stronger steel is eliminated. ACR
requested that, if this proposal is adopted, a drum manufacturer's use
of this equivalence formula be communicated through a particular unique
mark, thus advising persons responsible for reuse or reconditioning of
this equivalence formula being used.
RSPA is confident that the equivalence formula adopted in this
final rule provides an equivalent level of safety and drum integrity.
The language in the paragraph (b)(7) leakproofness testing waiver for
stainless steel drums requires a thickness of one and one-half times
the thickness prescribed for reuse, thus precluding use of any thinner
drums.
An adjustment to Footnote 1, which specifies a minimum thickness of
0.82 mm body and 1.11 mm head and corresponds with ISO 3574, is adopted
as proposed. Commenters supporting this proposed change included ACR,
several chemical manufacturing companies, the Association of Waste
Hazardous Materials Transporters, and a drum manufacturer. Two
commenters, a different drum manufacturer and the Steel Shipping
Container Institute (SSCI), opposed this proposal, stating that this
request from ACR was driven by economic considerations, not safety.
SSCI claimed that technology for determining minimum thicknesses is
readily available. The drum manufacturer opposing this change stated
that if the footnote adjustment was adopted as proposed, RSPA should
provide a transition period for drum manufacturers to deplete their
inventory of material rendered obsolete by this change.
RSPA is making this adjustment to Footnote 1 to standardize minimum
thickness requirements with breakpoints commonly recognized by
international standards, not to provide any economic benefit to
industry. RSPA also is revising Footnote 1 to authorize metal drums or
jerricans constructed with a minimum thickness of 0.82 mm body and 1.09
mm heads until December 31, 1996. After that date, drums must be
constructed with heads meeting a minimum thickness of 1.11 mm. This
delay will provide drum manufacturers additional time to deplete
existing inventory and build an inventory of new material.
Paragraph (b)(7)(iv)(C) is revised as proposed to clarify that
there are established conditions which must be met before an approval
is granted by the Associate Administrator for Hazardous Materials
Safety to allow relief from leakproofness testing for a packaging
constructed of a material or thickness not otherwise authorized in the
exception.
Paragraph (c)(2) prescribes reconditioning requirements for non-
bulk packagings other than metal drums. In the NPRM, RSPA proposed a
revision to this paragraph to clarify that repairing or replacing a
bung or removable gasket in a plastic closed head (UN 1H1) drum is not
considered reconditioning. Both SSCI and ACR opposed this proposed
change, stating that replacing gaskets or closures on a plastic drum is
plastic drum reconditioning. SSCI claimed that a change in the material
of a drum is reconditioning or remanufacturing, and that changing
location, type or size of gasket material or properties affecting the
performance of the gasket is considered design type changes requiring
complete design qualification testing. The SSCI also warned that this
proposal downplays the significance of gaskets in minimizing leaks and
will shift drum purchases from steel to plastic drums to save costs in
reconditioning and leaktesting. In RSPA's view, simply ``replacing'' a
bung or gasket in a plastic closed head drum is not reconditioning. In
this final rule, RSPA is clarifying in paragraph (c)(2) that repair or
replacement of a bung or a removable gasket in a plastic closed head
(UN 1H1) drum with a bung or gasket that is of the same design and
material as the original bung or gasket, and provides equivalent
performance, is not considered reconditioning and does not subject the
drum to reconditioning marking requirements or to leakproofness testing
requirements if it is otherwise excepted from leakproofness testing.
Section 173.32. As proposed, RSPA is reinstating pressure testing
requirements for DOT 57 portable tanks in paragraph (e)(2)(i). RSPA
also is amending paragraph (d) to allow plastic discharge valves for
certain stainless steel DOT 57 tanks constructed before October 1,
1996. Allowing a plastic discharge valve on these tanks eliminates the
need for an existing exemption, DOT-E-10916, and permits continued use
of thousands of portable tanks with a proven safety record. Two
comments were received in response to the proposal, both supporting
revisions to this section.
RSPA is adding a new paragraph (t) which allows the remarking of
certain portable tanks currently authorized under DOT exemptions as DOT
51 portable tanks. These portable tanks were in full conformance with
the requirements for DOT 51 portable tanks, including the ASME Code
``U'' stamp, except for the location of fill and discharge outlets.
The changes adopted in this final rule relating to the location of
outlets on DOT 51 portable tanks will allow for the elimination of
numerous exemptions based on the design and excellent safety record of
these portable tanks. RSPA believes that as a minimum, the following
exemptions will be affected:
DOT-E 6518
DOT-E 8196
DOT-E 9401
DOT-E 9402
[[Page 50620]]
DOT-E 9632
DOT-E 9718
DOT-E 10032
DOT-E 10171
DOT-E 10193
DOT-E 10291
DOT-E 10567
DOT-E 11239
DOT-E 11275
DOT-E 11313
DOT-E 11331
DOT-E 11539
DOT-E 11589
DOT-E 11604
DOT-E 11658
DOT-E 11661
Persons holding other exemptions which they believe are impacted by
changes adopted by this final rule should contact RSPA.
Section 173.115. Paragraph (b)(1) is revised as proposed to reflect
the correct conversion of 280 kPa to read ``280 kPa (40.6 psia)'' for
informational purposes.
Section 173.120 and Appendix H to Part 173. Based on requests from
industry and comments supporting this proposed revision, RSPA is adding
a new paragraph (b)(3) to specify a procedure for testing combustible
liquids with a flash point above 60.5 deg. C (141 deg. F) and below
93 deg.C (200 deg. F) for the ability to sustain combustion. Appendix H
to Part 173 is revised to provide additional test temperatures in
paragraph 5.(h) for combustible liquids that closely parallel the
approach for flammable liquids.
Sections 173.121, 173.125, and 173.127. As proposed, RSPA is
adopting a clarification of the methods for determining packing groups
described in Secs. 173.121(a), 173.125(a), and 173.127(b) for Class 3,
Class 4, and Class 5 materials, respectively.
Section 173.133. RSPA is revising as proposed the wording ``more
than one packing group and hazard zone'' in paragraph (b)(1) to read
``more than one packing group or hazard zone''. One commenter expressed
support for the proposed change, stating that it will clarify the
determination of applicable packing groups.
Section 173.134. Paragraph (a)(4) limits the definition of
regulated medical waste to exclude discarded cultures and stocks of
infectious substances. In this final rule, paragraph (b) is revised as
proposed by adding a new paragraph (b)(4) authorizing discarded
cultures and stocks in Biosafety Levels 1, 2 and 3, as defined in HHS
Publication No. (CDC) 93-8395, Biosafety in Microbiological and
Biomedical Laboratories, 3rd Edition, May 1993, Section II to be
described and packaged as regulated medical waste rather than
infectious substances. Packagings must conform to Packing Group II
performance requirements. Transport of these materials is limited to
private or contract motor freight carriers in dedicated service to the
transportation of medical waste. Commenters uniformly supported this
proposed change. One commenter referenced a recent Center for Disease
Control proposed list of infectious substances capable of causing
substantial harm to human health. This commenter believed all discarded
cultures and stocks of infectious substances not on this proposed list
should be eligible for regulation as regulated medical waste. Another
commenter believed RSPA should provide even more relief for these
materials by allowing them to be packaged in OSHA-authorized containers
conforming to DOT's general packaging standards, and also should allow
private carriers transporting these types of cultures and stocks to
backhaul non-food products if trailers are properly disinfected. It is
RSPA's view that these suggested changes are beyond the scope of this
rulemaking.
Section 173.151. A new paragraph (d) is added as proposed to
incorporate limited quantity provisions for Division 4.3 (dangerous
when wet) solid materials in Packing Groups II and III. This amendment
aligns the HMR with limited quantity exceptions contained in the UN
Recommendations.
Section 173.156. Paragraph (b)(2) is revised as proposed to remove
the 30 kg (66 pounds) weight restriction for ORM-D materials packaged
in ``display packs'' which are offered for transportation, or
transported, by highway or rail between a manufacturer, a distribution
center, and a retail outlet. These display packs are inner receptacles
of ORM-D materials which are secured in corrugated fiberboard trays and
then stacked and placed within a strong outer container. Each outer
container is strapped to a wooden pallet with steel or polyester
strapping to form an integral part of the packaging. All commenters
addressing this issue supported the proposal; however, several
commenters requested that the net weight of each display pack be raised
from 250 kg (550 pounds) to 525 kg (1155 pounds) to reflect the weight
limit authorized in an exemption recently granted for this type of
packaging. RSPA believes that display packs should be limited to 250 kg
(550 pounds) net weight until satisfactory experience is gained under
the exemption at the higher weight.
RSPA proposed an exception for transportation of ORM-D materials to
disposal facilities in paragraph (b)(1) to allow discarded consumer
commodities to be transported from manufacturing, distribution or
retail facilities to a disposal facility when packaged in large boxes
or overpacks exceeding 30 kg (66 pounds). RSPA received comments
supporting this proposal from The Conference on the Safe Transportation
of Hazardous Articles (petitioner for this change) and the National
Wholesale Druggists' Association. The Association of Waste Hazardous
Materials Transporters opposed the proposal, stating it has the
potential for abuse. This commenter believed the proposal was not in
the public interest and will create confusion about the regulatory
status of discarded material, which may be subject to regulation as
either a solid waste or hazardous waste.
RSPA does not agree. However, based on further review of this
proposal, RSPA is revising the proposed provision to require that the
transportation of discarded consumer commodities to a disposal facility
must be from a single point of origin. RSPA believes that limiting the
consolidation of discarded consumer commodities in one shipping unit
from one offeror establishes an appropriate condition for such
transportation, taking into account other requirements such as
Secs. 173.24 and 173.24a.
Section 173.158. Paragraph (d) is revised as proposed to authorize
additional packagings for nitric acid in concentrations of 90 percent
or greater when offered for transportation or transported by rail,
highway or water. A combination packaging consisting of a 1A2, 1B2, 1D,
1G, 1H2, 3H2 or 4G outer packaging with inner glass packagings of 2.5 L
(0.66 gallons) or less capacity cushioned with a non-reactive,
absorbent material and packed within a leak-tight packaging of metal or
plastic is authorized.
In addition, RSPA is revising paragraph (f)(1) as proposed to
authorize 6HH1 and 6HA1 composite packagings with PFA Teflon inner
receptacles for nitric acid concentrations of 70 percent or less. These
composite packagings are authorized under the provisions of three
exemptions and have demonstrated an equivalent level of safety.
Section 173.170. RSPA is adding a new non-bulk packaging section
for black powder for small arms when transported domestically and
reclassed as Division 4.1. For consistency with comparable provisions
for smokeless powder for small arms, RSPA is revising approval
procedures as proposed in the NPRM by requiring that black powder must
be examined and approved for Division 4.1 classification and the
[[Page 50621]]
complete package must be of the same type as that approved under
Sec. 173.56.
Section 173.183. As proposed, RSPA is adding a packaging
authorization to allow the use of polypropylene inner packagings for
nitrocellulose base film.
Section 173.225. Paragraph (a) is amended as proposed to specify
that inner plastic packagings of a combination packaging used for
transporting organic peroxides must be constructed of new resin. The
one commenter responding to this proposal, the Organic Peroxide
Producers Safety Division of the Society of the Plastics Industry,
petitioned for the change. RSPA agrees with the commenter that most
regulated organic peroxides are too sensitive to contamination to be
stored in packages manufactured from ``resin of unknown history.''
Section 173.306. Paragraph (i)(1) is removed as proposed and
paragraphs (i)(2) through (i)(4) are redesignated accordingly as
paragraphs (i)(1) through (i)(3). In addition, RSPA is revising the
introductory text of paragraph (i) to clarify that flammability of
aerosols is based on obtaining a positive test result from any of the
three methods contained in this paragraph. This approach is consistent
with the ICAO Technical Instructions.
Section 173.314. RSPA is adopting a seasonal filling limit for tank
cars containing anhydrous ammonia and liquefied petroleum gas based on
winter filling reference temperatures of 29 deg.C (85 deg.F), 32 deg.C
(90 deg.F), and 38 deg.C (100 deg.F), for insulated tanks, thermally-
protected and jacketed tanks, and noninsulated tanks, respectively.
These filling limits would authorize a winter filling limit greater
than that authorized in the HM-181 final rule. RSPA believes that these
filling limits will ensure safety in transit while providing economic
relief from the requirements adopted in the HM-181 final rule.
Commenters uniformly supported this proposed change. The National
Industrial Transportation League stated this change strikes an
appropriate balance between safety and efficiency by avoiding the
necessity for increasing the number of tank car shipments (and
corresponding risk of spills) in winter months to achieve the same
overall volume. The National Propane Gas Association also supported
this proposal for tank cars and indicated its intent to submit a
proposal to RSPA later this year for adoption of seasonal filling
limits for cargo tanks.
Part 178
Sections 178.245 and 178.245-1. RSPA is making several editorial
changes for clarity and one significant change to allow DOT
Specification 51 portable tanks to have openings at locations other
than the top or one end of the tank under certain circumstances.
Commenters supported the proposal to allow bottom outlets on tank
containers, citing safety and economic benefits.
Section 178.245-4. As proposed, RSPA is adding a new paragraph (e)
to require that a DOT 51 portable tank in an ISO framework for
containerized transportation must meet the requirements specified in 49
CFR Parts 450-453.
Section 178.245-6. The first sentence of paragraph (a) is amended
as proposed to require the nameplate to be in close proximity to the
ASME plate.
Section 178.270-12. RSPA is amending paragraph (a) as proposed to
notify manufacturers, owners and approval agencies of the requirements
for the number and type of closures required for filling and discharge
connections located below the normal liquid level of IM portable tanks.
Section 178.601. Paragraph (g)(8) is added to list changes in one
or more design elements which would constitute a different drum design
type. Commenters supported the addition of this paragraph, but
recommended revisions to be consistent with an approval issued to SSCI.
RSPA agrees and is revising these provisions accordingly.
Section 178.705. As proposed, a correction is made to the constant
in the equivalence thickness formula for U.S. Standard Units in
paragraph (c)(1)(iv)(B) to ensure that the resulting thickness is in
inches.
Paragraph (c)(2) of this section specifies pressure relief devices
for metal IBCs. RSPA proposed adding a new sentence in paragraph
(c)(2)(ii) to clarify that the specified start-to-discharge pressure
requirements do not apply to fusible links unless these links are the
sole source of pressure relief for the IBC. RSPA's proposal did not
change any existing UN requirements, but simply clarified that the
start-to discharge pressure requirements in 178.705(c)(2)(ii) did not
apply to fusible devices if such devices are used in addition to other
venting devices. If fusible devices are the sole means for providing
venting relief capacity, an IBC marked ``31A'' must not exceed 65 kPa
(9 psig) at the fusible device operating temperature.
Several commenters requested that RSPA not adopt this amendment as
proposed. It appears commenters are requesting an exception from start-
to-discharge pressure requirements when fusible devices are the sole
means of pressure relief capacity. This exception would not be
consistent with pressure relief requirements for IBCs in the UN
Recommendations. The UN Recommendations specify pressure relief
capabilities for an IBC regardless of the type of pressure relief
device utilized. To maintain international consistency, such an
exception should first be proposed and adopted in the UN
Recommendations.
RSPA is adopting this amendment in paragraph (c)(2)(ii) essentially
as proposed, but is replacing the phrase ``fusible links'' with
``fusible devices'' to more accurately describe these devices. This
revision is based on a comment by the Rigid Intermediate Bulk Container
Association.
IV. 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. The rule is not
considered a significant rule under the Regulatory Policies and
Procedures of the Department of Transportation [44 FR 11034].
The economic impact of this final rule is expected to result in
only minimal costs to certain persons subject to the HMR and may result
in modest cost savings to a small number of persons subject to the HMR
and to the agency. Because of the minimal economic impact of this rule,
preparation of a regulatory impact analysis or a regulatory evaluation
is not warranted.
B. Executive Order 12612
This final rule has been analyzed in accordance with the principles
and criteria contained in Executive Order 12612 (``Federalism'').
Federal law expressly preempts State, local, and Indian tribe
requirements applicable to the transportation of hazardous material
that cover certain subjects and are not substantively the same as
Federal requirements. 49 U.S.C. 5125(b)(1). These subjects are:
(1) The designation, description, and classification of hazardous
material;
(2) The packing, repacking, handling, labeling, marking, and
placarding of hazardous material;
(3) The preparation, execution, and use of shipping documents
pertaining to hazardous material, and requirements respecting the
number, content, and placement of such documents;
(4) The written notification, recording, and reporting of the
unintentional release in transportation of hazardous material; or
(5) The design, manufacturing, fabrication, marking, maintenance,
[[Page 50622]]
reconditioning, repairing, or testing of a package or container which
is represented, marked, certified, or sold as qualified for use in the
transportation of hazardous material.
This final rule preempts 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 law (49 U.S.C. 5125(b)(2)) provides that if DOT issues a
regulation concerning any of the covered subjects, DOT 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. RSPA has determined that the
effective date of Federal preemption for these requirements will be
January 1, 1997. Thus, RSPA lacks discretion in this area, and
preparation of a federalism assessment is not warranted.
C. Regulatory Flexibility Act
This final rule responds to petitions for rulemaking. It is
intended to provide clarification of the regulations and relax certain
requirements. Therefore, I certify that this final rule will not have a
significant economic impact on a substantial number of small entities.
D. Paperwork Reduction Act
There are no new information collection requirements in this final
rule.
E. 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.

[[Page 50628]]
annually in accordance with section IX of the ASME Code. In addition to
the essential variables named therein, the following must be considered
to be essential variables: number of passes, thickness of plate, heat
input per pass, and manufacturer's identification of rod and flux. The
number of passes, thickness of plate and heat input per pass may not
vary more than 25 percent from the procedure qualification. Records of
the qualification must be retained for at least 5 years by the tank
manufacturer and made available to duly identified representatives of
the Department of Transportation or the owner of the tank.
(2) Impact tests must be made on a lot basis. A lot is defined as
100 tons or less of the same heat and having a thickness variation no
greater than plus or minus 25 percent. The minimum impact required for
full-sized specimens shall be 20 foot-pounds (or 10 foot-pounds for
half-sized specimens) at 0 deg. F Charpy V-Notch in both the
longitudinal and transverse direction. If the lot test does not pass
this requirement, individual plates may be accepted if they
individually meet this impact requirement.
