Sec.  397.71  Federal standards.

    (a) A State or Indian tribe shall comply with the Federal standards 
under paragraph (b) of this section when establishing, maintaining or 
enforcing specific NRHM routing designations over which NRHM may or may 
not be transported.
    (b) The Federal standards are as follows:
    (1) Enhancement of public safety. The State or Indian tribe shall 
make a finding, supported by the record to be developed in accordance 
with paragraphs (b)(2)(ii) and (b)(3)(iv) of this section, that any NRHM 
routing designation enhances public safety in the areas subject to its 
jurisdiction and in other areas which are directly affected by such 
highway routing designation. In making such a finding, the State or 
Indian tribe shall consider:
    (i) The factors listed in paragraph (b)(9) of this section; and
    (ii) The DOT ``Guidelines for Applying Criteria to Designate Routes 
for Transporting Hazardous Materials,'' DOT/RSPA/OHMT-89-02, July 1989 
\1\ or its most current version; or an equivalent routing analysis which 
adequately considers overall risk to the public.

    (2) Public participation. Prior to the establishment of any NRHM 
routing designation, the State or Indian tribe shall undertake the 
following actions to ensure participation by the public in the routing 
process:
    (i) The State or Indian tribe shall provide the public with notice 
of any proposed NRHM routing designation and a 30-day period in which to 
comment. At any time during this period or following review of the 
comments received, the State or Indian tribe shall decide whether to 
hold a public hearing on the proposed NRHM route designation. The public 
shall be given 30 days prior notice of the public hearing which shall be 
conducted as described in paragraph (b)(2)(ii) of this section. Notice 
for both the comment period and the public hearing, if one is held, 
shall be given by publication in at least two newspapers of general 
circulation in the affected area or areas and shall contain a complete 
description of the proposed routing designation, together with the date, 
time, and location of any public hearings. Notice for both the comment 
period and any public hearing may also be published in the official 
register of the State.
    (ii) If it is determined that a public hearing is necessary, the 
State or Indian tribe shall hold at least one public hearing on the 
record during which the public will be afforded the opportunity

[[Page 481]]

to present their views and any information or data related to the 
proposed NRHM routing designation. The State shall make available to the 
public, upon payment of prescribed costs, copies of the transcript of 
the hearing, which shall include all exhibits and documents presented 
during the hearing or submitted for the record.
    (3) Consultation with others. Prior to the establishment of any NRHM 
routing designation, the State or Indian tribe shall provide notice to, 
and consult with, officials of affected political subdivisions, States 
and Indian tribes, and any other affected parties. Such actions shall 
include the following:
    (i) At least 60 days prior to establishing a routing designation, 
the State or Indian tribe shall provide notice, in writing, of the 
proposed routing designation to officials responsible for highway 
routing in all other affected States or Indian tribes. A copy of this 
notice may also be sent to all affected political subdivisions. This 
notice shall request approval, in writing, by those States or Indian 
tribes, of the proposed routing designations. If no response is received 
within 60 days from the day of receipt of the notification of the 
proposed routing designation, the routing designation shall be 
considered approved by the affected State or Indian tribe.
    (ii) The manner in which consultation under this paragraph is 
conducted is left to the discretion of the State or Indian tribe.
    (iii) The State or Indian tribe shall attempt to resolve any concern 
or disagreement expressed by any consulted official related to the 
proposed routing designation.
    (iv) The State or Indian tribe shall keep a record of the names and 
addresses of the officials notified pursuant to this section and of any 
consultation or meeting conducted with these officials or their 
representatives. Such record shall describe any concern or disagreement 
expressed by the officials and any action undertaken to resolve such 
disagreement or address any concern.
    (4) Through routing. In establishing any NRHM routing designation, 
the State or Indian tribe shall ensure through highway routing for the 
transportation of NRHM between adjacent areas. The term ``through 
highway routing'' as used in this paragraph means that the routing 
designation must ensure continuity of movement so as to not impede or 
unnecessarily delay the transportation of NRHM. The State or Indian 
tribe shall utilize the procedures established in paragraphs (b)(2) and 
(b)(3) of this section in meeting these requirements. In addition, the 
State or Indian tribe shall make a finding, supported by a risk analysis 
conducted in accordance with paragraph (b)(1) of this section, that the 
routing designation enhances public safety. If the risk analysis shows--
    (i) That the current routing presents at least 50 percent more risk 
to the public than the deviation under the proposed routing designation, 
then the proposed routing designation may go into effect.
    (ii) That the current routing presents a greater risk but less than 
50 percent more risk to the public than the deviation under the proposed 
routing restriction, then the proposed routing restriction made by a 
State or Indian tribe shall only go into effect if it does not force a 
deviation of more than 25 miles or result in an increase of more than 25 
percent of that part of a trip affected by the deviation, whichever is 
shorter, from the most direct route through a jurisdiction as compared 
to the intended deviation.
    (iii) That the current route has the same or less risk to the public 
than the deviation resulting from the proposed routing designation, then 
the routing designation shall not be allowed.
    (5) Agreement of other States; burden on commerce. Any NRHM routing 
designation which affects another State or Indian tribe shall be 
established, maintained, or enforced only if:
    (i) It does not unreasonably burden commerce, and
    (ii) It is agreed to by the affected State or Indian tribe within 60 
days of receipt of the notice sent pursuant to paragraph (b)(3)(i) of 
this section, or it is approved by the Administrator pursuant to Sec.  
397.75.
    (6) Timeliness. The establishment of a NRHM routing designation by 
any State or Indian tribe shall be completed within 18 months of the 
notice

[[Page 482]]

given in either paragraph (b)(2) or (b)(3) of this section, whichever 
occurs first.
    (7) Reasonable routes to terminals and other facilities. In 
establishing or providing for reasonable access to and from designated 
routes, the State or Indian tribe shall use the shortest practicable 
route considering the factors listed in paragraph (b)(9) of this 
section. In establishing any NRHM routing designation, the State or 
Indian tribe shall provide reasonable access for motor vehicles 
transporting NRHM to reach:
    (i) Terminals,
    (ii) Points of loading, unloading, pickup and delivery, and
    (iii) Facilities for food, fuel, repairs, rest, and safe havens.
    (8) Responsibility for local compliance. The States shall be 
responsible for ensuring that all of their political subdivisions comply 
with the provisions of this subpart. The States shall be responsible for 
resolving all disputes between such political subdivisions within their 
jurisdictions. If a State or any political subdivision thereof, or an 
Indian tribe chooses to establish, maintain, or enforce any NRHM routing 
designation, the Governor, or Indian tribe, shall designate a routing 
agency for the State or Indian tribe, respectively. The routing agency 
shall ensure that all NRHM routing designations within its jurisdiction 
comply with the Federal standards in this section. The State or Indian 
tribe shall comply with the public information and reporting 
requirements contained in Sec.  397.73.
    (9) Factors to consider. In establishing any NRHM routing 
designation, the State or Indian tribe shall consider the following 
factors:
    (i) Population density. The population potentially exposed to a NRHM 
release shall be estimated from the density of the residents, employees, 
motorists, and other persons in the area, using United States census 
tract maps or other reasonable means for determining the population 
within a potential impact zone along a designated highway route. The 
impact zone is the potential range of effects in the event of a release. 
Special populations such as schools, hospitals, prisons, and senior 
citizen homes shall, among other things, be considered when determining 
the potential risk to the populations along a highway routing. 
Consideration shall be given to the amount of time during which an area 
will experience a heavy population density.
    (ii) Type of highway. The characteristics of each alternative NRHM 
highway routing designation shall be compared. Vehicle weight and size 
limits, underpass and bridge clearances, roadway geometrics, number of 
lanes, degree of access control, and median and shoulder structures are 
examples of characteristics which a State or Indian tribe shall 
consider.
    (iii) Types and quantities of NRHM. An examination shall be made of 
the type and quantity of NRHM normally transported along highway routes 
which are included in a proposed NRHM routing designation, and 
consideration shall be given to the relative impact zone and risks of 
each type and quantity.
    (iv) Emergency response capabilities. In consultation with the 
proper fire, law enforcement, and highway safety agencies, consideration 
shall be given to the emergency response capabilities which may be 
needed as a result of a NRHM routing designation. The analysis of the 
emergency response capabilities shall be based upon the proximity of the 
emergency response facilities and their capabilities to contain and 
suppress NRHM releases within the impact zones.
    (v) Results of consultation with affected persons. Consideration 
shall be given to the comments and concerns of all affected persons and 
entities provided during public hearings and consultations conducted in 
accordance with this section.
    (vi) Exposure and other risk factors. States and Indian tribes shall 
define the exposure and risk factors associated with any NRHM routing 
designations. The distance to sensitive areas shall be considered. 
Sensitive areas include, but are not limited to, homes and commercial 
buildings; special populations in hospitals, schools, handicapped 
facilities, prisons and stadiums; water sources such as streams and 
lakes; and natural areas such as parks, wetlands, and wildlife reserves.
    (vii) Terrain considerations. Topography along and adjacent to the 
proposed NRHM routing designation that

[[Page 483]]

may affect the potential severity of an accident, the dispersion of the 
NRHM upon release and the control and clean up of NRHM if released shall 
be considered.
    (viii) Continuity of routes. Adjacent jurisdictions shall be 
consulted to ensure routing continuity for NRHM across common borders. 
Deviations from the most direct route shall be minimized.
    (ix) Alternative routes. Consideration shall be given to the 
alternative routes to, or resulting from, any NRHM route designation. 
Alternative routes shall be examined, reviewed, or evaluated to the 
extent necessary to demonstrate that the most probable alternative 
routing resulting from a routing designation is safer than the current 
routing.
    (x) Effects on commerce. Any NRHM routing designation made in 
accordance with this subpart shall not create an unreasonable burden 
upon interstate or intrastate commerce.
    (xi) Delays in transportation. No NRHM routing designations may 
create unnecessary delays in the transportation of NRHM.
    (xii) Climatic conditions. Weather conditions unique to a highway 
route such as snow, wind, ice, fog, or other climatic conditions that 
could affect the safety of a route, the dispersion of the NRHM upon 
release, or increase the difficulty of controlling it and cleaning it up 
shall be given appropriate consideration.
    (xiii) Congestion and accident history. Traffic conditions unique to 
a highway routing such as: traffic congestion; accident experience with 
motor vehicles, traffic considerations that could affect the potential 
for an accident, exposure of the public to any release, ability to 
perform emergency response operations, or the temporary closing of a 
highway for cleaning up any release shall be given appropriate 
consideration.
