DEPARTMENT OF TRANSPORTATION

Federal Motor Carrier Safety Administration


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 provides revisions to the National Hazardous 
Materials Route Registry (NHMRR) reported to FMCSA from April 1, 2021 
through March 31, 2022. 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: These revisions are effecive May 11, 2022.

FOR FURTHER INFORMATION CONTACT: Ms. Melissa Williams, Hazardous 
Materials Division, Office of Enforcement and Compliance, FMCSA, 1200 
New Jersey Avenue SE, Washington, DC 20590-0001, (202) 366-4163, 
[email protected]. Office hours are from 9 a.m. to 5 p.m., ET., 
Monday through Friday, except for Federal holidays.

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 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 definitions 
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, 49 CFR 397.73 establishes public information and 
reporting requirements for NRHM. States or Tribal governments are 
required to furnish information regarding any new or changed routes to 
FMCSA within 60 days after establishment. Under 49 CFR 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 five updates to the NHMRR in Federal Register notices 
on August 8, 2016 (81 FR 52518), August 9, 2018 (83 FR 39500), 
September 24, 2019 (84 FR 50098), June 3, 2020 (85 FR 34284), and June 
17, 2021 (86 FR 32306).
    This notice provides revisions to the NHMRR, reported to FMCSA from 
April 1, 2021 through March 31, 2022. 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, September 24, 2019, June 3, 2020 and June 17, 2021 notices. 
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 the 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 49 CFR 397.73 and 397.103, 
the NHMRR is being revised as follows:

Table 2.--California--Designated NRHM Routes
    Route Order Designator ``A13P-2.0-O2'' is revised.
    Route Order Designator ``A17P-2.0-C'' is revised.
Table 3.--California--HRCQ/RAM Routes
    Route Order Desginator ``B6A-2.0B'' is revised.
Table 4.--Washington--Restricted HM Routes

[[Page 28860]]

    Route Order Desginator ``C'' is added.

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 HRCQ/RAM. 
Restriction codes identify the routes along which a driver may not 
transport specified HM shipments. Table 1 presents information on each 
restriction and designation code.
