Background
This rulemaking updates existing regulations governing new
construction, reconstruction, resurfacing (except for maintenance
resurfacing), restoration, and rehabilitation projects on the NHS
(including the Interstate System), by incorporating by reference the
current versions of design standards and standard specifications
previously adopted and incorporated by reference under 23 CFR 625.4,
and removing the outdated or superseded versions of these standards and
specifications. Several of these design standards and standard
specifications were established by the American Association of State
Highway and Transportation Officials (AASHTO) and the American Welding
Society (AWS) and were previously adopted by FHWA through rulemaking.
The new standards or specifications replace previous versions of these
documents and represent the most recent refinements that professional
organizations have formally accepted. The FHWA formally adopts them for
NHS projects.
The revisions include referencing the 2016 edition of the AASHTO A
Policy on Design Standards--Interstate System; the 2017 edition of
Transportation Materials, parts 1-3; the 2017 edition of the AASHTO
Load and Resistance Factor Design (LRFD) Bridge Construction
Specifications; the 2015 edition of the AASHTO/AWS D1.5M/D1.5:2015
Bridge Welding Code (as reprinted in 2016), with 2018 Interim
Revisions; and the 2017 edition of the AASHTO LRFD Bridge Design
Specifications. The revisions will also adopt two alternative
specifications: the 2013 edition of AASHTO's Standard Specifications
for Structural Supports of Highway Signs, Luminaires, and Traffic
Signals (including Errata September 2013), with 2015 Interim Revisions,
as well as the 2015 edition of AASHTO's LRFD Specifications for
Structural Supports for Highway Signs, Luminaires, and Traffic Signals,
with 2017 and 2018 Interim Revisions.
The AASHTO is an organization that represents 52 State highway and
transportation agencies (including the District of Columbia and Puerto
Rico). Its members consist of the duly constituted heads and other
chief officials of those agencies. The Secretary of Transportation is
an ex-officio member, and DOT staff participates in various AASHTO
activities as nonvoting representatives. Among other functions, AASHTO
develops and issues standards, specifications, policies, guides, and
related materials for use by the States for highway projects. Many of
the standards, policies, and standard specifications that were approved
by FHWA and incorporated into 23 CFR part 625 were developed and issued
by AASHTO.
While these adopted standards and specifications apply to all
projects on the NHS (including the Interstate System), FHWA encourages
the use of flexibility and a context-sensitive approach to consider a
full range of project and user needs and the impacts to the community
and natural and human environment. The FHWA also encourages State
departments of transportation (State DOT) and local agencies to
consider using design exceptions to achieve a design that balances
project and user needs, performance, cost, environmental implications,
and community values. These adopted design standards provide a range of
acceptable values for highway features, and this flexibility should
allow for a design that best suits the desires of the community while
satisfying the purpose for the project and needs of its users.
At a minimum, State DOTs and local agencies should select design
values based on an evaluation of the context of the facility, needs of
all the various project users, safety, mobility (i.e., traffic
performance), human and natural environmental impacts, and project
costs. For most situations, there is sufficient flexibility within the
range of acceptable values to achieve a balanced design. However, when
this is not possible, a design exception may be appropriate. State and
local agencies may consider designs that deviate from the design
standards when warranted based on the conditions, context, and
consequences of the proposed projects. Additional information on FHWA's
adopted design standards and design exceptions is available at: http://www.fhwa.dot.gov/design/standards and in FHWA's publication titled
Mitigation Strategies for Design Exceptions, available at: http://safety.fhwa.dot.gov/geometric/pubs/mitigationstrategies/fhwa_sa_07011.pdf.
Discussion Under 1 CFR Part 51
The documents that FHWA is incorporating by reference are
reasonably available to interested parties, primarily State DOTs and
local agencies carrying out Federal-aid highway projects. These
documents represent the most recent refinements that professional
organizations have formally accepted and are currently in use by the
transportation industry. The documents are also available for review at
DOT's National Transportation Library or may be obtained from AASHTO or
AWS. The specific standards are discussed in greater detail elsewhere
in this preamble.
Section-by-Section Discussion of Changes to 23 CFR Part 625
The FHWA is removing the introductory text of Sec. 625.4. It is
duplicative of information contained in paragraph (d) and does not meet
Office of the Federal Register formatting
[[Page 54878]]
requirements for incorporation by reference.
The FHWA is revising Sec. 625.4(a)(2) to replace the reference to
the January 2005 edition of A Policy on Design Standards--Interstate
System with the May 2016 edition. This Policy is a comprehensive manual
to assist State DOTs and local agencies in administrative, planning,
and educational efforts pertaining to design formulation for projects
on the Dwight D. Eisenhower National System of Interstate and Defense
Highways (Interstate). The AASHTO May 2016 edition incorporates the
latest research and current industry practices, and is applicable to
new construction and reconstruction projects on the Interstate except
in Alaska and Puerto Rico (23 U.S.C. 103(c)(1)(B)(ii)). Resurfacing,
restoration, and rehabilitation projects must meet the Interstate
standards that were in place at the time of original construction or
inclusion into the Interstate System. The updated guide clarifies
ambiguities in the prior edition and provides additional flexibility
regarding the design traffic volumes to be accommodated. It increases
the median width in rural areas to reduce cross-median crashes and adds
recommendations about extended access control and multimodal
considerations at interchanges. Basic criteria for other geometric
design standards remain essentially the same. The Agency considers the
changes made in the 2016 version minor in nature.
With respect to the design standards and standards specifications
for bridges and structures under Sec. 625.4(b), FHWA is adopting the
current versions of the standards and specifications it has previously
adopted from AASHTO and AWS. The updated documents contain changes that
represent discoveries or improvements in the state-of-the-knowledge and
practices of State DOTs and local agencies that have occurred since the
previous standards and specifications were incorporated by reference
into 23 CFR part 625.
The FHWA is revising Sec. 625.4(b)(2) to incorporate by reference
the current version of the revised AASHTO bridge construction
specifications entitled LRFD Bridge Construction Specifications, 4th
Edition. These specifications, which are intended for use in the
construction of bridges, employ the LRFD methodology and are designed
to be used in conjunction with the below referenced AASHTO LRFD Bridge
Design Specifications. Changes in the 4th Edition reflect the latest
research and developments, and specifications promulgated by AASHTO.
The FHWA is revising Sec. 625.4(b)(3) to incorporate by reference
the current version of the revised AASHTO bridge design specifications
entitled AASHTO LRFD Bridge Design Specifications, 8th Edition. The
AASHTO LRFD Bridge Design Specifications are intended for use in the
design, evaluation, and rehabilitation of bridges, and are mandated by
the FHWA for use on all bridges using Federal funding. These
Specifications employ the LRFD methodology using factors developing
from current statistical knowledge of loads and structural performance.
Changes in the 8th Edition reflect the latest research, developments,
and specifications promulgated by AASHTO.
The FHWA is making a minor editorial correction to the reference to
the LRFD Movable Highway Bridge Design Specifications referenced in
paragraph Sec. 625.4(b)(4) to change ``including'' to ``with'' when
citing the Interim Revisions, but is not changing the material that is
already incorporated.
The FHWA is revising Sec. 625.4(b)(5) to incorporate by reference
the current version of the revised AASHTO bridge welding code entitled
AASHTO/AWS D1.5M/D1.5:2015-AMD1 Bridge Welding Code; AASHTO, as
corrected and reprinted in 2016, and including 2018 Interim Revisions
(The 2015 publication was the 7th edition). This document covers AASHTO
welding requirements for welded highway bridges made from carbon and
low-alloy construction steels. Chapters cover design of welded
connections, workmanship, technique, procedure and performance
qualification, inspection, and stud welding. Changes in the 7th
Edition, including the 2018 Interim Revisions, reflect the latest
research, developments, and specifications promulgated by AASHTO and
AWS.
The FHWA is revising Sec. 625.4(b)(7) to incorporate by reference
two alternative Specifications applicable to the structural design of
supports for highway signs, luminaires, and traffic signals. State DOTs
must choose one of these alternative Specifications to guide the
design, fabrication, and erection of these types of supports. The first
alternative is the most current version of the revised AASHTO
structural support specification entitled Standard Specifications for
Structural Supports for Highway Signs, Luminaires, and Traffic Signals,
6th Edition, AASHTO, 2013, with 2015 Interim Revisions. Changes in the
2015 Interim Revisions reflect more recent research, developments, and
specifications promulgated by AASHTO than the prior adopted version.
The second alternative Specification is AASHTO's LRFD Specifications
for Structural Supports for Highway Signs, Luminaires, and Traffic
Signals, 1st Edition, AASHTO, 2015, with 2017 and 2018 Interim
Revisions. While the LRFD specification is a more comprehensive,
improved specification that reflects the latest research and knowledge,
the agency has determined that design pursuant to either Specification
provides for safe and reliable structural supports for highways signs,
luminaires, and traffic signals.
The FHWA is revising Sec. 625.4(c)(2) to incorporate by reference
the current version of the revised AASHTO sampling and testing
specification entitled 2017 Edition of Transportation Materials AASHTO,
2017. It contains specifications, test methods, and provisional
standards commonly used in the construction of highway facilities. This
edition of the standard specifications will replace those adopted by
AASHTO in 1995. Changes in the 2016 standard specifications reflect
current materials and testing technologies and practices.
The FHWA is revising Sec. 625.4(c)(3) to update the title and
cross-reference of the referenced regulation to ``Quality Assurance
Procedures for Construction.''
Use of the updated standards will be required for all NHS projects
authorized to proceed with design activities on or after the effective
date of the final rule, subject to the exceptions in 23 CFR 625.3(f).
Summary Discussion of Comments Received in Response to the NPRM
On May 11, 2018, FHWA published an NPRM in the Federal Register at
83 FR 21972 soliciting public comments on its proposal to update the
existing regulations. The following presents an overview of the
comments received to the NPRM. The docket contained 4 total comments.
The FHWA appreciates the feedback the commenters provided, carefully
reviewed and analyzed all the comments that were submitted, and made
revisions to the NPRM to incorporate suggestions where necessary.
An individual commented that the Standard Specifications for
Structural Supports for Highway Signs, Luminaires, and Traffic Signals,
6th Edition, AASHTO, 2013 with 2015 Interim Revisions had been
superseded by the LRFD Specifications for Structural Supports for
Highway Signs, Luminaires, and Traffic Signals, 1st Edition, AASHTO,
2015, with 2017 and 2018 Interim Revisions.
[[Page 54879]]
The LRFD Specification does not supersede the Standard
Specification. At this time, many State DOTs are using the Standard
Specification and are not ready to fully implement the LRFD
Specification. Because the LRFD specification is a more comprehensive,
improved specification that reflects the latest research and knowledge,
FHWA plans to work with AASHTO to develop a timeline to phase out use
of the Standard Specification in the future. However, the agency has
determined that design pursuant to either Specification provides for
safe and reliable structural supports for highways signs, luminaires,
and traffic signals.\1\ Therefore, in the interim, FHWA is adopting the
updated Standard Specification and the LRFD Specification as
alternative Specifications applicable to the structural design of
supports for highway signs, luminaires, and traffic signals. States
DOTs must choose one of these alternative Specifications to guide the
design, fabrication, and erection of these types of supports.
Accordingly, FHWA has revised Sec. 625.4(b)(7) to accommodate State
DOTs that are ready to begin transitioning to the LRFD Specification.
---------------------------------------------------------------------------
\1\ This determination is supported by National Cooperative
Highway Research Program Report 796: Development and Calibration of
AASHTO LRFD Specifications for Structural Supports for Highway
Signs, Luminaires, and Traffic Signals, which found that ``[t]he
[LRFD Specifications] were calibrated using the AASHTO [Standard
Specifications] allowable stress design method as a baseline,''
which means that both the Standard Specifications and the LRFD
Specifications ensure a consistent level of safety.
---------------------------------------------------------------------------
That individual also commented that 2018 Interim Revisions had been
released for the 2015 Bridge Welding Code, 7th Edition.
These Interim Revisions were not available when the NPRM was
developed, however, FHWA has decided to incorporate the 2018 Interim
Revisions by reference in this final rule because they reflect the
latest research, developments, and specifications promulgated by AASHTO
and AWS.
An individual commenter suggested that rather than adopt specific
editions of standards, FHWA should adopt ``the most current version at
the time of contract advertisement,'' to eliminate the need to
continuously revise 23 CFR part 625.
Procedures and requirements for incorporation by reference are
covered in 1 CFR part 51, which requires that the language
incorporating a publication by reference be precise and complete and
must clearly state the title, date, edition, author, publisher and
identification number of the publication. Therefore, no change was made
to the final rule.
An individual commented that the updated standards would not allow
certain products and therefore provided for a lower margin of safety.
The final rule adopts current versions of industry publications and
does not pertain to specific merchandise or products. Use of these
current publications will improve safety because the newer versions
incorporate updated research within each specific area of concern.
Therefore, no change was made to the final rule.
An individual commented that existing practice of allowing for
design exceptions undermined existing regulations.
Design exceptions, which have been allowed by the regulations for
decades, are essential to developing projects that are congruent with
the natural surroundings, community context, and the purpose and need
of the project. Therefore, no change was made to the final rule.
Rulemaking Analyses and Notices
Executive Order 12866 (Regulatory Planning and Review), Executive Order
13563 (Improving Regulation and Regulatory Review), Executive Order
13771 (Reducing Regulation and Controlling Regulatory Costs), and USDOT
Regulatory Policies and Procedures
The FHWA has determined that this action does not constitute a
significant regulatory action within the meaning of Executive Order
(E.O.) 12866 or within the meaning of DOT regulatory policies and
procedures. The amendments update several industry design standards and
standard specifications adopted and incorporated by reference under 23
CFR part 625 and removes the corresponding outdated or superseded
versions of these standards and specifications. In addition, this
action complies with the principles of E.O. 13563. After evaluating the
costs and benefits of these amendments, FHWA anticipates that the
economic impact of this rulemaking is minimal. These incremental
changes are not anticipated to adversely affect, in any material way,
any sector of the economy. In addition, these changes will not create a
serious inconsistency with any other agency's action or materially
alter the budgetary impact of any entitlements, grants, user fees, or
loan programs. These updated standards and specifications represent the
most recent refinements that professional organizations have formally
accepted. The FHWA anticipates that the economic impact of this
rulemaking will be minimal; therefore, a full regulatory evaluation is
not necessary. Finally, this rule is not an E.O. 13771 regulatory
action because it is not significant under E.O. 12866.
Regulatory Flexibility Act
In compliance with the Regulatory Flexibility Act (Pub. L. 96-354;
5 U.S.C. 60l-612), FHWA has evaluated the effects of this final rule on
small entities, such as local governments and businesses. Based on the
evaluation, FHWA anticipates that this action does not have a
significant economic impact on a substantial number of small entities.
The amendments update several industry design standards and standard
specifications adopted and incorporated by reference under 23 CFR part
625. The FHWA believes the projected impact upon small entities that
utilize Federal-aid highway program funding for the development of
highway improvement projects on the NHS is negligible. Therefore, I
certify that the action will not have a significant economic impact on
a substantial number of small entities.
Unfunded Mandates Reform Act of 1995
The FHWA has determined that this rule does not impose unfunded
mandates as defined by the Unfunded Mandates Reform Act of 1995 (Pub.
L. 104-4, March 22, 1995, 109 Stat. 48). The actions in this final rule
will not result in the expenditure by State, local, and Tribal
governments, in the aggregate, or by the private sector, of $155
million or more in any 1 year (when adjusted for inflation) in 2014
dollars for either State, local, and Tribal governments in the
aggregate, or by the private sector. In addition, the definition of
``Federal Mandate'' in the Unfunded Mandates Reform Act excludes
financial assistance of the type in which State, local, or Tribal
governments have authority to adjust their participation in the program
in accordance with changes made in the program by the Federal
Government. The Federal-aid highway program permits this type of
flexibility.
Executive Order 13132 (Federalism Assessment)
The FHWA has analyzed this final rule in accordance with the
principles and criteria contained in E.O. 13132. The FHWA has
determined that this action does not have sufficient federalism
implications to warrant the preparation of a federalism assessment. The
FHWA has also determined that this action does not preempt any State
law or State regulation or affect the
[[Page 54880]]
States' ability to discharge traditional State governmental functions.
Executive Order 12372 (Intergovernmental Review)
The regulations implementing E.O. 12372 regarding intergovernmental
consultation on Federal programs and activities apply to this program.
This E.O. applies because State and local governments are directly
affected by this regulation, which is a condition on Federal highway
funding. Local entities should refer to the Catalog of Federal Domestic
Assistance Program Number 20.205, Highway Planning and Construction,
for further information.
Paperwork Reduction Act
Under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501, et
seq.), Federal agencies must obtain approval from the Office of
Management and Budget for each collection of information they conduct,
sponsor, or require through regulations. The FHWA has determined that
this final rule does not contain collection of information requirements
for the purposes of the PRA.
National Environmental Policy Act
The FHWA has analyzed this final rule for the purposes of the
National Environmental Policy Act (NEPA) (42 U.S.C. 4321, et seq.) and
has determined that this action does not have any effect on the quality
of the human and natural environment because it only makes technical
changes and incorporate by reference the latest versions of design
standards and standard specifications previously adopted and
incorporated by reference under 23 CFR part 625 and removes the
corresponding outdated or superseded versions of these standards and
specifications. The final rule qualifies as a categorical exclusion to
NEPA under 23 CFR 771.117(c)(20).
Executive Order 13175 (Tribal Consultation)
The FHWA has analyzed this final rule under EO13175, and believes
that it will not have substantial direct effects on one or more Indian
Tribes, does not impose substantial direct compliance costs on Indian
Tribal governments, and does not preempt Tribal law. This rule does not
impose any direct compliance requirements on Indian Tribal governments
nor does it have any economic or other impacts on the viability of
Indian Tribes. Therefore, a Tribal summary impact statement is not
required.
Executive Order 13211 (Energy Effects)
The FHWA has analyzed this final rule under E.O. 13211, Actions
Concerning Regulations that Significantly Affect Energy Supply,
Distribution, or Use. The FHWA has determined that this action is not a
significant energy action under the E.O. and is not likely to have a
significant adverse effect on the supply, distribution, or use of
energy. Therefore, a Statement of Energy Effects is not required.
Executive Order 12630 (Taking of Private Property)
The FHWA has analyzed this rule under E.O. 12630, Governmental
Actions and Interference with Constitutionally Protected Property
Rights. The FHWA does not anticipate that this action will effect a
taking of private property or otherwise have taking implications under
E.O. 12630.
Executive Order 12988 (Civil Justice Reform)
This action meets applicable standards in sections 3(a) and 3(b)(2)
of E.O. 12988, Civil Justice Reform, to minimize litigation, eliminate
ambiguity, and reduce burden.
Executive Order 13045 (Protection of Children)
The FHWA has analyzed this action under E.O. 13045, Protection of
Children from Environmental Health Risks and Safety Risks. The FHWA
certifies that this action will not cause an environmental risk to
health or safety that may disproportionately affect children.
Regulation Identifier Number
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.
