Hazardous Materials: Incorporation of Certain Cargo Tank Special
Permits Into Regulations
AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA),
DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The Pipeline and Hazardous Materials Safety Administration is
proposing to amend the Hazardous Materials Regulations to incorporate
provisions contained in certain widely used or longstanding cargo tank
special permits that are granted to multiple parties and have an
established safety record. Special permits allow a company or
individual to package or ship a hazardous material in a manner that
varies from the regulations provided an equivalent level of safety is
maintained. The proposed revisions are intended to provide wider access
to the regulatory flexibility offered in the special permits and
eliminate the need for numerous renewal requests, thereby, facilitating
commerce activity and reducing paperwork burdens while maintaining an
appropriate level of safety.
DATES: Comments must be received by August 20, 2010. A 30 day comment
period is appropriate for this rulemaking because it proposes to
incorporate long-standing, widely used special permits into the HMR.
These
[[Page 42365]]
special permits have well-established safety records. Incorporation of
these special permits would reduce the compliance burden and cost on
both industry and government by removing the need to apply for special
permits.

SUPPLEMENTARY INFORMATION:
I. Background
II. Overview of Proposed Amendments
III. Summary Review of Amendments
IV. Regulatory Analyses and Notices
I. Background
The Pipeline and Hazardous Materials Safety Administration (PHMSA)
is proposing to amend the Hazardous Materials Regulations (HMR; 49 CFR
Parts 171-180) to incorporate certain requirements based on existing
special permits issued by PHMSA under 49 CFR Part 107, Subpart B
(Sec. Sec. 107.101 to 107.127). A special permit sets forth
alternative requirements (variances) to the requirements in the HMR by
means that achieve a safety level that at the least corresponds to the
safety level required under the regulations and that is consistent with
the public interest. Congress expressly authorized DOT to issue these
variances in the Hazardous Materials Transportation Act of 1975.
The HMR generally are performance oriented regulations, which
provides the regulated community with a certain amount of flexibility
in meeting safety requirements. Even so, not every transportation
situation can be anticipated and built into the regulations. Innovation
is a strength of our economy and the hazardous materials community is
particularly strong at developing new materials and technologies and
innovative ways of moving materials. Special permits enable the
hazardous materials industry to quickly, effectively and safely
integrate new products and technologies into the production and
transportation stream. Thus, special permits provide a mechanism for
testing new technologies, promoting increased transportation efficiency
and productivity, and ensuring global competitiveness.
A special permit must achieve at least an equivalent level of
safety to that specified in the HMR. Implementation of new technologies
and operational techniques can enhance safety because the authorized
operations or activities achieve a greater level of safety than
currently required under the regulations. Special permits also reduce
the volume and complexity of the HMR by addressing unique or infrequent
transportation situations that would be difficult to accommodate in
regulations intended for use by a wide range of shippers and carriers.
PHMSA conducts ongoing reviews of special permits to identify widely
used and longstanding special permits with an established safety record
for adoption into regulations for broader applicability. Converting
these special permits into regulations reduces paperwork burdens and
facilitates commerce while maintaining an acceptable level of safety.
Additionally, adoption of special permits as rules of general
applicability provides wider access to the benefits and regulatory
flexibility of the provisions granted in the special permits. Factors
that influence whether a specific special permit is a candidate for
regulatory action include: the safety record for hazardous materials
transported; transportation operations conducted under a special
permit; the potential for broad application of a special permit;
suitability of provisions in the special permit for incorporation into
the HMR; rulemaking activity in related areas; and agency priorities.
Although PHMSA does not issue a special permit to an industry
association, PHMSA may issue a special permit to members of an industry
association when many of its members have a common interest in
obtaining authority to perform a specific transportation activity,
there is no large business entity to take the lead in seeking such
authority, and the association has the resources to gather the
necessary information and perform any necessary research. Special
permits issued to the members of associations are potentially among the
most suitable types of special permit for later adoption into the HMR.
Such special permits have broad applicability; moreover, many of them
have been in effect for a number of years and have demonstrated safety
records.
The six special permits addressed in this notice of proposed
rulemaking (NPRM), which authorize cargo tank transportation operations
not specifically permitted under the HMR, were initially issued to
members of industry associations or similar organizations. They have
well-established safety records and, thus, are candidates for
incorporation into the HMR. Incorporating these special permits into
the HMR would eliminate the need for over 10,000 current grantees to
reapply for the renewal of six special permits every four years and for
PHMSA to process the renewal applications.
Incorporation of these special permits into the HMR also eliminates
a significant paperwork burden. Unless otherwise excepted by this
agency, a copy of each special permit must be maintained at each
facility where a packaging is manufactured under a special permit, at
each facility where a package is offered or re-offered for
transportation under a special permit carried on board each cargo
vessel or aircraft, and in some cases must be carried aboard each
transport vehicle used to transport a hazardous material under a
special permit.
[[Page 42366]]
II. Overview of Proposed Amendments
In this NPRM, PHMSA is proposing to revise the HMR by providing:
Authorization to transport liquefied petroleum gas (LPG)
in non-DOT specification cargo tank motor vehicles known as moveable
fuel storage tenders that are used exclusively for agricultural
purposes.
Authorization to transport Division 6.1 liquid soil
pesticide fumigants in DOT Specification MC 306 and DOT 406 cargo tank
motor vehicles and DOT 57 portable tanks, used exclusively for
agricultural purposes.
Authorization to transport certain hazardous materials
used for roadway striping in non-DOT specification cargo tanks.
Authorization for private motor carriers to transport LPG
in consumer storage containers with quantities greater than 5 percent
of the container's water capacity.
Authorization to transport nurse tanks securely mounted on
field trucks.
Authorization for nurse tanks with missing or illegible
ASME plates to continue to be used in anhydrous ammonia service under
specified conditions.
III. Summary Review of Amendments
A. Moveable Fuel Storage Tenders
Special permit SP 11209 authorizes the transportation of LPG in
non-DOT specification cargo tank motor vehicles, commonly known as
moveable fuel storage tenders, used exclusively for agricultural
purposes. Moveable fuel storage tenders are used to supply LPG fuel to
farmers for crop drying, crop irrigation, flame weeding, plant
defoliation prior to harvest, and other agricultural operations.
The special permit has been in effect since 1994 and has been
utilized by upwards of 3,400 grantees. A review of the Hazardous
Materials Incident Data library did not reveal any incidents related to
this special permit over, at least, the past ten years. Each vehicle
operated under this special permit conforms to the ASME Code in effect
at the time of its manufacture. The design and use of these vehicles is
included in the provisions of the National Fire Protection Association
pamphlet no. 58, Storage and Handling of Liquefied Petroleum Gases.
PHMSA proposes to incorporate the terms of special permit SP 11209
into the HMR by amending Sec. 173.5 to authorize the transportation of
LPG in moveable fuel storage tenders used exclusively for agricultural
purposes and operated by a private motor carrier. (A ``private motor
carrier,'' as defined in interpretation letters issued by PHMSA, is a
carrier who transports the business's own products and does not provide
such transportation service to other businesses). As proposed, a non-
DOT specification cargo tank motor vehicle used as a moveable fuel
storage tender must: (1) Have a minimum design pressure of 250 psig;
(2) conform to the requirements of the ASME Code in effect at the time
the cargo tank was manufactured and marked accordingly; (3) have a
water capacity of 1,200 gallons or less; (4) conform to applicable
requirements in National Fire Protection Association (NFPA) Pamphlet
No. 58; and (5) be mounted securely on a motor vehicle. In addition,
the cargo tank must be filled as prescribed in Sec. 173.315(b). When
filled, transportation of a moveable fuel storage tender would be
limited to movements over local roads between fields using the shortest
practical distance. In addition, transportation of a moveable storage
fuel tender to an LPG distribution facility for re-filling would be
permitted only if it contains no more than 5 percent of its water
capacity.
B. Liquid Soil Pesticide Fumigants
Special permit SP 13113 authorizes the transportation of Division
6.1 liquid soil pesticide fumigants in MC 306 and DOT 406 cargo tank
motor vehicles and DOT 57 portable tanks used exclusively for
agricultural purposes. Transportation of these materials is limited to
private motor carriage and must be between a bulk loading facility and
farms (including between farms) not exceeding 150 miles from one
another. Liquid soil pesticide fumigants are used by farmers as an
alternative to the agricultural use of methyl bromide to ensure the
adequate protection of crops from pesticide infestation, and
consequently, to preserve agricultural productivity.
This special permit has been in effect since 2002 and has been
utilized by hundreds of grantees. A review of the Hazardous Materials
Incident Data library did not reveal any incidents related to this
special permit since the date of its issuance. Prior to 2002, when this
material was classed as Dichloropropenes, 6.1, UN2047, PG III, it was
routinely shipped, according to 49 CFR 173.242 in MC 306 and DOT 406
cargo tanks and DOT 57 portable tanks. The same tanks have been widely
used to transport gasoline, a low flashpoint PGII liquid. The pressure
relief systems and bottom discharge equipment on the cargo tanks offer
equivalent safety in terms of containment and operation of pressure
relief systems. Also, stainless steel DOT 57 portable tanks provide
comparable containment to metal, rigid plastic, and composite
Intermediate Bulk Containers (IBCs), which are authorized for transport
of Division 6.1 liquid soil pesticide fumigants under Sec. 173.202.
PHMSA proposes to incorporate the terms of special permit SP 13113
into the HMR by also amending Sec. 173.5 to authorize the
transportation of Division 6.1 liquid soil pesticide fumigants in MC
306 and DOT 406 cargo tank motor vehicles and DOT 57 portable tanks by
a private motor carrier, exclusively for agricultural purposes. As
proposed, MC 306 and DOT 406 cargo tank motor vehicles used for the
transportation of these fumigants must: (1) Meet qualification and
maintenance requirements (including periodic testing and inspection) in
accordance with Subpart E of Part 180; and (2) conform to the pressure
relief system requirements specified in Sec. 173.243(b)(1). In
addition, MC 306 cargo tank motor vehicles must be equipped with stop-
valves capable of being remotely closed by manual and mechanical means;
and DOT 406 cargo tanks must conform to the bottom outlet requirements
specified in Sec. 173.243(b)(2). Also as proposed, DOT 57 portable
tanks used to transport Division 6.1 liquid soil pesticide fumigants
must be constructed of stainless steel. Finally, MC 306 and DOT 406
cargo tank motor vehicles and DOT 57 portable tanks used to transport
Division 6.1 liquid soil pesticide fumigants must be used exclusively
for agricultural purposes, operated by a private motor carrier; and
limited to transport between a bulk loading facility and farms
(including between farms) not to exceed 150 miles from one another.
C. Non-DOT Specification Cargo Tanks Used for Roadway Striping
Special permit SP 12284 authorizes the transportation in commerce
of certain hazardous materials used for roadway striping in non-DOT
specification cargo tanks. These non-DOT specification cargo tanks are
used for the low hazard job of applying roadway striping to paved roads
throughout the United States.
The special permit has been in effect since 1999 and has been
utilized by over 100 grantees. A review of the Hazardous Materials
Incident Data library did not reveal any incidents related to this
special permit since the date of its issuance. Based on the safety
record, PHMSA is proposing to incorporate the provisions of special
permit SP 12284 into the HMR by adding a new paragraph (c) to Sec.
173.5a to authorize the transportation of certain hazardous
[[Page 42367]]
materials used for roadway striping to be transported in non-DOT
specification cargo tanks provided the conditions specified in the new
paragraph are met. The new paragraph (c) would specify conditions that
include packaging specifications, inspection and testing requirements,
requirements for maintaining records, and operational controls.
Consistent with the special permit, paragraph (c) also would include
marking requirements in addition to applicable marking and placarding
requirements in subparts D and F. The section title heading would also
be revised to reflect the addition of non-DOT specification cargo tanks
used for roadway striping into this section. Finally, Sec. 173.242(b)
would be revised to include the authorization to use non-DOT
specification cargo tanks used for roadway striping.
D. LPG Storage Containers
Currently, in accordance with Sec. 173.315(j)(4), LPG may not be
transported in consumer storage containers that contain greater than 5
percent of the container's water capacity. Special permit SP 13341
authorizes the transportation by private motor carrier of LPG in
consumer storage containers in quantities greater than 5 percent of the
container's water capacity. The storage containers are designed for
permanent installation on consumer premises. The special permit
authorizes the transportation of a storage container from the consumer
location to the container owner's nearest LPG plant.
The special permit has been in effect since 2004 and has been
utilized by several thousand grantees. A review of the Hazardous
Materials Incident Data library did not reveal any incidents related to
this special permit since the date of its issuance. Prior to 1998,
consumer storage containers containing greater than 5 percent water
capacity were routinely transported without any known incidents. The
prohibition of transporting containers with more than 5 percent water
capacity resulted from concern of the potential for confusion between
ASME and DOT tanks, as ASME tanks are not designed to be lifted by the
lugs with product inside. This proposal requires lifting with slings,
not by the lugs. Also, transporting a tank with some product is
sometimes preferable from a safety standpoint than removing LPG from a
tank at a residence.
PHMSA proposes to incorporate the terms of special permit SP 13341
into the HMR by revising Sec. 173.315(j) to authorize the
transportation of LPG in consumer storage containers containing greater
than 5 percent of the container's water capacity. As proposed, the
storage container must have a water capacity not exceeding 500 gallons
and be ASME ``U'' stamped to indicate that it was designed and
constructed in accordance with ASME Code requirements. In addition, the
container must be inspected for leaks, corroded or abraded areas,
dents, weld distortions, or any other conditions that could make the
container unsafe for transportation. PHMSA also proposes to require
that: (1) Only one storage container may be transported at one time on
a motor vehicle; (2) the storage container must be lifted by slings,
not lifting lugs; and (3) the storage container must be loaded and
secured on the motor vehicle so that the container is well-secured
against movement and completely within the envelope of the vehicle.
Finally, PHMSA proposes to limit transportation to one-way movement
from the consumer's premises to the container owner's nearest facility.
E. Nurse Tanks
Nurse tanks are non-DOT specification cargo tanks used to transport
and apply anhydrous ammonia fertilizers. The HMR authorize the use of
nurse tanks operated by private motor carriers exclusively for
agricultural purposes provided that the nurse tank: (1) Has a minimum
design pressure of 250 psig and meets the requirements of Section VIII
of the ASME code in effect at the time the nurse tank was manufactured;
(2) is equipped with pressure relief valves; (3) has a capacity of
3,000 gallons or less; (4) is loaded to a filling density no greater
than 56 percent; and (5) is securely mounted on a farm wagon. Because
they are non-DOT specification containers, currently nurse tanks are
not subject to periodic inspection, testing, or requalification
requirements.
Nurse tanks mounted on field trucks. Special permit SP 10950
authorizes the use of a nurse tank securely mounted on a field truck.
Field trucks are specifically designed and equipped to improve safety
and efficiency by being more maneuverable and more stable than a farm
wagon when moving over hilly terrain. These trucks are operated in
remote rural areas in eastern Washington, Oregon, and northern Idaho
within a short distance of the fertilizer distribution point. The
special permit has been in effect since 1993 and has been utilized by
over a hundred grantees. A review of the Hazardous Materials Incident
Data library did not reveal any incidents related to this special
permit since the date of its issuance. Tanks operated under this
special permit are subject to the periodic testing requirements under
Subpart E of Part 180.
Based on the safety record, PHMSA is proposing to incorporate the
provisions of SP 10950 into the HMR by adding a new paragraph (m)(2) to
Sec. 173.315. As proposed, nurse tanks mounted on field trucks would
be required to be inspected and tested in accordance with Subpart E of
Part 180 as specified for MC 331 cargo tanks. Operations would be
restricted to rural roads within 50 miles of the distribution site
where the nurse tank is loaded.
Nurse tanks with missing or illegible ASME plates. As indicated
above, nurse tanks must be manufactured in accordance with the
applicable ASME Code requirements in effect at the time of manufacture.
The ASME Code requires tanks built to its specifications to have an
attached plate that lists the manufacturer, maximum allowable working
pressure, minimum design metal temperature, and the year of
manufacture. A number of nurse tanks are missing the required ASME
plates or have illegible ASME plates. Special permit SP 13554 permits
the continued use in anhydrous ammonia service of nurse tanks with
missing or illegible ASME plates provided the tanks are inspected and
tested. Specifically, the tanks must undergo an external visual
inspection and testing using the procedures specified in Sec.
180.407(d), thickness tested using the procedures specified in Sec.
180.407(i), and pressure tested using the procedures specified in Sec.
180.407(g). The special permit also establishes minimum head and shell
thickness, below which the nurse tank must be removed from service.
The special permit has been in effect since 2004 and has been
utilized by thousands of grantees. A review of the Hazardous Materials
Incident Data library did not reveal any incidents related to this
special permit since the date of its issuance. Although 49 CFR
173.315(m) requires that a nurse tank ``meet the requirements of the
edition of Section VIII of the ASME Code in effect at the time it was
manufactured and is marked accordingly,'' if the plate is missing or
illegible the nurse tank can not be used. Therefore, these additional
requirements that nurse tanks operating under the special permit must
follow (i.e. the thickness testing, the pressure testing, and the
external visual inspection), safely provides for the continued use of
these tanks.
In this NPRM, PHMSA is proposing to incorporate the terms of
special permit SP 13554 into the HMR by adding a new paragraph (m)(3)
in Sec. 173.315. As proposed, existing nurse tanks with
[[Page 42368]]
missing or illegible ASME plates that successfully pass the required
inspections and tests and are marked with a unique identifier would be
authorized to remain in service.
Finally, in Sec. 171.7, we are proposing to revise the entries,
American Society of Mechanical Engineers (ASME), National Board of
Boiler and Pressure Vessel Inspectors (NBIC) and the National Fire
Protection Association (NFPA) to reflect the addition of the
incorporated by reference materials to the applicable newly proposed
regulatory text.
IV. Rulemaking Analyses and Notices
A. Statutory/Legal Authority for This Rulemaking
This NPRM is published under the authority of 49 U.S.C. 5103(b)
which authorizes the Secretary to prescribe regulations for the safe
transportation, including security, of hazardous material in
intrastate, interstate, and foreign commerce. 49 U.S.C. 5117(a)
authorizes the Secretary of Transportation to issue a special permit
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. If adopted as proposed, the final
rule would amend the regulations incorporating provisions from certain
widely used and longstanding special permits that 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 proposed rule is not considered a significant regulatory
action under section 3(f) and was not reviewed by the Office of
Management and Budget (OMB). The proposed rule is not considered a
significant rule under the Regulatory Policies and Procedures order
issued by the Department of Transportation [44 FR 11034].
In this notice, PHMSA proposes to amend the HMR by incorporating
alternatives this agency has permitted under widely used and
longstanding special permits with established safety records that we
have determined meet the safety criteria for inclusion in the HMR.
Incorporation of these special permits into regulations of general
applicability will provide shippers and carriers with additional
flexibility to comply with established safety requirements, thereby
reducing transportation costs and increasing productivity. In addition,
the proposals in this NPRM will reduce the paperwork burden on industry
and this agency caused by continued renewals of special permits. The
provisions of this proposed rule will promote the continued safe
transportation of hazardous materials while reducing transportation
costs for the industry and administrative costs for the agency.
C. Executive Order 13132
This proposed rule was analyzed in accordance with the principles
and criteria contained in Executive Order 13132 (``Federalism''). This
proposed rule would preempt State, local and Indian Tribe requirements
but does not propose 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 governments. Therefore, the consultation and funding
requirements of Executive Order 13132 do not apply. Federal hazardous
material transportation law, 49 U.S.C. 5101-5128, 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 materials.
This proposed rule addresses covered subject items 2, 3, and 5 and
would preempt any State, local, or Indian Tribe requirements not
meeting the ``substantively the same'' standard. Federal hazardous
materials transportation law provides at 49 U.S.C. 5125(b)(2) that if
PHMSA issues a regulation concerning any of the covered subjects, PHMSA
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. PHMSA proposes the effective
date of Federal preemption be 90 days from publication of a final rule
in this matter in the Federal Register.
D. Executive Order 13175
This proposed rule was analyzed in accordance with the principles
and criteria contained in Executive Order 13175 (``Consultation and
Coordination with Indian Tribal Governments''). Because this proposed
rule does not have Tribal implications and does not impose substantial
direct compliance costs on Indian Tribal governments, the funding and
consultation requirements of Executive Order 13175 do not apply.
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
proposed rule incorporates into the HMR certain widely used special
permits. Incorporation of these special permits into regulations of
general applicability will provide shippers and carriers with
additional flexibility to comply with established safety requirements,
thereby reducing transportation costs and increasing productivity.
Therefore, I certify this rule will not have a significant economic
impact on a substantial number of small entities.
This proposed 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
This proposed rule does not impose new information collection
requirements. PHMSA has an approved information collection under OMB
Control Number 2137-0051, ``Rulemaking, Special Permits, and Preemption
Requirements,'' currently being reviewed for renewal by OMB. This NPRM
may result in a decrease in the annual burden and costs under OMB
Control Number 2137-0051 due to
[[Page 42369]]
proposed changes to incorporate provisions contained in certain widely
used or longstanding special permits that have an established safety
record.
Under the Paperwork Reduction Act of 1995, no person is required to
respond to an information collection unless it has been approved by OMB
and displays a valid OMB control number. Section 1320.8(d), title 5,
Code of Federal Regulations requires that PHMSA provide interested
members of the public and affected agencies an opportunity to comment
on information and recordkeeping requests.
This notice identifies a revised information collection request
that PHMSA will submit to OMB for approval based on the requirements in
this proposed rule. PHMSA has developed burden estimates to reflect
changes in this proposed rule. PHMSA estimates that the information
collection and recordkeeping burden as proposed in this rule would be
decreased as follows:
OMB Control No. 2137-0051
Decrease in Annual Number of Respondents: 185.
Decrease in Annual Responses: 185.
Decrease in Annual Burden Hours: 185.
Decrease in Annual Burden Costs: $7,400.
PHMSA specifically requests comments on the information collection
and recordkeeping burdens associated with developing, implementing, and
maintaining these requirements for approval under this proposed rule.
Requests for a copy of this information collection should be
directed to Deborah Boothe or T. Glenn Foster, Office of Hazardous
Materials Standards (PHH-11), Pipeline and Hazardous Materials Safety
Administration, 1200 New Jersey Avenue, SE., Washington, DC 20590-0001,
Telephone (202) 366-8553.
Address written comments to the Dockets Unit as identified in the
ADDRESSES section of this rulemaking. We must receive comments
regarding information collection burdens prior to the close of the
comment period identified in the DATES section of this rulemaking. In
addition, you may submit comments specifically related to the
information collection burden to the PHMSA Desk Officer, Office of
Management and Budget, at fax number (202) 395-6974.
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 contained in the heading of
this document may be used to cross-reference this action with the
Unified Agenda.
H. Unfunded Mandates Reform Act of 1995
This proposed rule does not impose unfunded mandates under the
Unfunded Mandates Reform Act of 1995. It does not result in costs of
$141.3 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 that significantly affect the quality of the human
environment.
The hazardous materials regulatory system is a risk management
system that is prevention oriented and focused on identifying a hazard
and reducing the probability and quantity of a hazardous materials
release. Hazardous materials are categorized by hazard analysis and
experience into hazard classes and packing groups. The regulations
require each shipper to classify a material in accordance with these
hazard classes and packing groups; the process of classifying a
hazardous material is itself a form of hazard analysis. Further, the
regulations require the shipper to communicate the material's hazards
by identifying the hazard class, packing group, and proper shipping
name on shipping papers and with labels on packages and placards on
transport vehicles. Thus, the shipping paper, labels, and placards
communicate the most significant findings of the shipper's hazard
analysis. Most hazardous materials are assigned to one of three packing
groups based upon its degree of hazard, from a high hazard Packing
Group I material to a low hazard Packing Group III material. The
quality, damage resistance, and performance standards for the
packagings authorized for the hazardous materials in each packing group
are appropriate for the hazards of the material transported.
Hazardous materials are transported by aircraft, vessel, rail, and
highway. The potential for environmental damage or contamination exists
when packages of hazardous materials are involved in transportation
incidents. The need for hazardous materials to support essential
services means transportation of highly hazardous materials is
unavoidable. However, these shipments frequently move through densely
populated or environmentally sensitive areas where the consequences of
an incident could be loss of life, serious injury, or significant
environmental damage. The ecosystems that could be affected by a
hazardous materials release during transportation include atmospheric,
aquatic, terrestrial, and vegetal resources (for example, wildlife
habitats). The adverse environmental impacts associated with releases
of most hazardous materials are short-term impacts that can be greatly
reduced or eliminated through prompt clean-up of the incident scene. In
this NPRM, we are requesting comments on the potential environmental
impacts of the proposals.
In this NPRM, PHMSA proposes to incorporate the terms of six
special permits into the HMR. Several of the proposals in this NPRM
involve the transportation of LPG. LPG is a Division 2.1 (flammable
gas) material that poses an explosive, fire, blast, or projection
hazard. If released, LPG may cause eye or skin irritation and, if
inhaled, it may irritate the respiratory tract. Moderate exposure may
cause headache or dizziness. Elevated exposure may cause
unconsciousness or respiratory arrest. Further, by diluting the oxygen
concentration in air below the level necessary to support life, LPG can
act as an asphyxiant. LPG is not known to cause long-term ecological
damage. The proposals in this NPRM are intended to ensure that LPG will
be transported in a variety of applications with no release from its
packaging and, thus, no adverse safety or environmental impacts.
One of the proposals in this NPRM involves Division 6.1 liquid soil
pesticide fumigants. Soil fumigation is a chemical control strategy
used independently or in conjunction with cultural and physical control
methods to reduce populations of soil organisms. Soil fumigants can
effectively control soil-borne organisms, such as nematodes, fungi,
bacteria, insects, weed seeds, and weeds. Different fumigants have
varying effects on the control of these pests. Some are pest specific,
while others are broad spectrum biocides that kill most soil organisms.
Soil fumigants are used in agriculture, nurseries, ornamental beddings,
forest systems, and other areas where soil-borne pests can harm or
devastate desirable plants. Because of treatment costs, applicators use
soil fumigants primarily on high value
[[Page 42370]]
crops, such as vegetables, fruits, and ornamentals. Control of soil-
borne pests increases plant aesthetics, plant quality and vigor, crop
yields, and ultimately profitability. Soil fumigants are closely
regulated by the Environmental Protection Agency to prevent adverse
health impacts to agricultural workers or bystanders (people who live,
work, or otherwise spend time near fields that are fumigated). The
proposals in this NPRM will help to ensure that liquid soil pesticide
fumigants are transported without incident on or between farms and the
bulk loading facility.
Several proposals in this NPRM address the transportation of
anhydrous ammonia. Anhydrous ammonia is a poisonous by inhalation (PIH)
material. When anhydrous ammonia is released into water, it floats on
the surface, rapidly dissolving into the water as ammonium hydroxide
while simultaneously boiling into the atmosphere as gaseous ammonia.
High concentrations of ammonia (greater than 1700 parts per million
(ppm)) in the atmosphere cause compulsive coughing and death, while
lower concentrations (lower than 700 ppm) cause eye and throat
irritation. Ammonia is lighter than air so that it dissipates in the
atmosphere, the rate of dissipation depending on weather.
In an aquatic or wetland environment, ammonium hydroxide would
cause fish, planktonic, and benthic organism mortality in the vicinity
of the release--the size depending on the volume of anhydrous ammonia
released. The chemical would also strip protective oils from the
feathers of shore birds, causing drowning or infection. Such die-offs
could spur high nutrient levels that could stimulate noxious blooms of
algae. Terrestrial vegetation would also be either damaged or killed,
depending on atmospheric concentrations.
The cleanup effort from a release of anhydrous ammonia would
require the removal of soil containing anhydrous ammonia quickly to
avoid contamination of the water table. Ammonia emissions would be
released during the cleanup effort as contaminated soil is disturbed.
The proposals in this NPRM will require certain nurse tanks used to
transport anhydrous ammonia to, from, and between farm fields to be
inspected and tested periodically to identify problems that would
result in a leak or release.
There are no significant environmental impacts associated with the
proposals in this NPRM, although PHMSA solicits comments on the
potential environmental impacts of the proposals in this NPRM. The
process through which special permits are issued requires the applicant
to demonstrate that the alternative transportation method or packaging
proposed provides an equivalent level of safety as that provided in the
HMR. Implicit in this process is that the special permit must provide
an equivalent level of environmental protection as that provided in the
HMR. Thus, incorporation of special permits as regulations of generally
applicability maintains the existing environmental protections built
into the HMR. In addition, the proposals applicable to nurse tanks will
enhance the integrity of those tanks, thereby reducing the possibility
of an anhydrous ammonia release.
