National Hazardous Materials Route Registry

AGENCY: Federal Motor Carrier Safety Administration (FMCSA), Department
of Transportation (DOT).

ACTION: Notice; revisions to the listing of designated and restricted
routes for hazardous materials.

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

SUMMARY: This notice makes revisions to the National Hazardous
Materials Route Registry (NHMRR) reported to the FMCSA from April 1,
2019 through March 31, 2020. The NHMRR is a listing, as reported by
States and Tribal governments, of all designated and restricted roads
and preferred highway routes for transportation of highway route
controlled quantities of Class 7 (radioactive materials) (HRCQ/RAM) and
non-radioactive hazardous materials (NRHM).

DATES: Effective date: June 3, 2020.

FOR FURTHER INFORMATION CONTACT: Ms. Melissa Williams, Hazardous
Materials Division, Office of Enforcement and Compliance, Federal Motor
Carrier Safety Administration, 1200 New Jersey Ave. SE, Washington, DC
20590, (202) 366-4163, melissa.williams@dot.gov.

SUPPLEMENTARY INFORMATION:

Legal Basis and Background

Paragraphs (a)(2) and (b) of section 5112 of title 49, United
States Code (U.S.C.), permit States and Tribal governments to designate
and limit highway routes over which hazardous materials (HM) may be
transported, provided the State or Tribal government complies with
standards prescribed by the Secretary of Transportation (the Secretary)
and meets publication requirements in section 5112(c). To establish
standards under paragraph (b), the Secretary must consult with the
States, and, under section 5112(c), coordinate with the States to
``update and publish periodically'' a list of currently effective HM
highway routing designations and restrictions. The requirements that
States and Tribal governments must follow to establish, maintain, or
enforce routing designations for the transport of placardable
quantities of NRHM are set forth in 49 CFR part 397, subpart C. Subpart
D of part 397 sets out the requirements for designating preferred
routes for highway route controlled quantities of HRCQ/RAM shipments as
an alternative, or in addition, to Interstate System highways. For
HRCQ/RAM shipments, Sec. 397.101 defines a preferred route as an
Interstate Highway for which no alternative route is designated by the
State; a route specifically designated by the State; or both. (See
Sec. 397.65 for the definition of ``NRHM'' and ``routing
designations.'')
Under a delegation from the Secretary,\1\ FMCSA has authority to
implement 49 U.S.C. 5112.
---------------------------------------------------------------------------

\1\ 49 CFR 1.87(d)(2).
---------------------------------------------------------------------------

Currently, Sec. 397.73 establishes public information and
reporting requirements for NRHM. States or Tribal governments are
required to furnish information to FMCSA regarding any new or changed
routes within 60 days after establishment. Under Sec. 397.103, a State
routing designation for HRCQ/RAM routes (preferred routes) as an
alternative, or in addition, to an Interstate System highway, is
effective when the authorized routing agency provides FMCSA with
written notification, FMCSA acknowledges receipt in writing, and the
route is published in FMCSA's NHMRR. The Office of Management and
Budget has approved these collections of information under control
number 2126-0014, Transportation of Hazardous Materials, Highway
Routing.
In this notice, FMCSA is merely performing the ministerial function
of updating and publishing the NHMRR based on input from its State and
Tribal partners under 49 U.S.C. 5112(c)(1). Accordingly, this notice
serves only to provide the most recent revisions to the NHMRR; it does
not establish any new public information and reporting requirements.

Updates to the NHMRR

FMCSA published the full NHMRR in a Federal Register notice on
April 29, 2015 (80 FR 23859). Since publication of the 2015 notice,
FMCSA published three updates to the NHMRR in Federal Register notices
on August 8, 2016 (81 FR 52518), August 9, 2018 (83 FR 39500) and
September 24, 2019 (84 FR 50098).
This notice makes revisions to the NHMRR, reported to the FMCSA
from April 1, 2019 through March 31, 2020. The revisions to the NHMRR
listings in this notice supersede and replace corresponding NHMRR
listings published in the April 29, 2015 notice and corresponding
revisions to the NHMRR listings published in the August 8, 2016, August
9, 2018, and September 24, 2019 notices. Please continue to refer to
the April 29, 2015 notice for additional background on the NHMRR and
the August 8, 2016 notice for the procedures for State and Tribal
government routing agencies to update their Route Registry listings and
contact information.
The full current NHMRR for each State is posted on FMCSA's website
at: https://www.fmcsa.dot.gov/regulations/hazardous-materials/national-hazardous-materials-route-registry.

Revisions to the NHMRR in This Notice

In accordance with the requirements of Sec. Sec. 397.73 and
397.103, the NHMRR is revised as follows:

Table 2.--California--Designated NRHM Routes

The existing Route Order Designator ``A1'' is revised to remove the
``I'' designation.
A new additional Route Order Designator ``A1'' is added and
assigned an ``I'' designation.
Route Order Designator ``A2'' with the ``I'' designation is
revised.
Route Order Designator ``A4A-3.0B'' with the ``I'' designation is
revised to remove the QA comment.
Route Order Designator ``A4A-3.0-D'' is revised to remove the ``B''

Route Order Key

Each listing in the NHMRR includes codes to identify each route
designation and each route restriction reported by the State.
Designation codes identify the routes along which a driver may or must
transport specified HM. Among the designation codes is one for
preferred routes, which apply to the transportation of a highway route
controlled quantity of Class 7 (radioactive) material. Restriction
codes identify the routes along which a driver may not transport
specified HM shipments.
