49 CFR Ch. I (10–1–23 Edition) 

§ 172.822 

(3) A rail carrier need not perform a 

rail transportation route analysis, al-
ternative route analysis, or route se-
lection process for any hazardous ma-
terial other than the materials speci-
fied in paragraph (a) of this section. 

(g) 

Rail carrier point of contact on rout-

ing issues. 

Each rail carrier must iden-

tify a point of contact (including the 
name, title, phone number and e-mail 
address) on routing issues involving 
the movement of materials covered by 
this section in its security plan and 
provide this information to: 

(1) State and/or regional Fusion Cen-

ters that have been established to co-
ordinate with state, local and tribal of-
ficials on security issues and which are 
located within the area encompassed 
by the rail carrier’s rail system; and 

(2) State, local, and tribal officials in 

jurisdictions that may be affected by a 
rail carrier’s routing decisions and who 
directly contact the railroad to discuss 
routing decisions. 

(h) 

Storage, delays in transit, and noti-

fication. 

With respect to the materials 

specified in paragraph (a) of this sec-
tion, each rail carrier must ensure the 
safety and security plan it develops 
and implements under this subpart in-
cludes all of the following: 

(1) A procedure under which the rail 

carrier must consult with offerors and 
consignees in order to develop meas-
ures for minimizing, to the extent 
practicable, the duration of any stor-
age of the material incidental to move-
ment (see § 171.8 of this subchapter). 

(2) Measures to prevent unauthorized 

access to the materials during storage 
or delays in transit. 

(3) Measures to mitigate risk to pop-

ulation centers associated with in- 
transit storage. 

(4) Measures to be taken in the event 

of an escalating threat level for mate-
rials stored in transit. 

(5) Procedures for notifying the con-

signee in the event of a significant 
delay during transportation; such noti-
fication must be completed within 48 
hours after the carrier has identified 
the delay and must include a revised 
delivery schedule. A significant delay 
is one that compromises the safety or 
security of the hazardous material or 
delays the shipment beyond its normal 
expected or planned shipping time. No-

tification should be made by a method 
acceptable to both the rail carrier and 
consignee. 

(i) 

Recordkeeping. 

(1) Each rail carrier 

must maintain a copy of the informa-
tion specified in paragraphs (b), (c), (d), 
(e), and (f) of this section (or an elec-
tronic image thereof) that is accessible 
at, or through, its principal place of 
business and must make the record 
available upon request, at a reasonable 
time and location, to an authorized of-
ficial of the Department of Transpor-
tation or the Department of Homeland 
Security. Records must be retained for 
a minimum of two years. 

(2) Each rail carrier must restrict the 

distribution, disclosure, and avail-
ability of information collected or de-
veloped in accordance with paragraphs 
(c), (d), (e), and (f) of this section to 
covered persons with a need-to-know, 
as described in parts 15 and 1520 of this 
title. 

(j) 

Compliance and enforcement. 

If the 

carrier’s route selection documenta-
tion and underlying analyses are found 
to be deficient, the carrier may be re-
quired to revise the analyses or make 
changes in route selection. If DOT finds 
that a chosen route is not the safest 
and most secure practicable route 
available, the FRA Associate Adminis-
trator for Safety, in consultation with 
TSA, may require the use of an alter-
native route. Prior to making such a 
determination, FRA and TSA will con-
sult with the Surface Transportation 
Board (STB) regarding whether the 
contemplated alternative route(s) 
would be economically practicable.

§ 172.822

Limitation on actions by 

states, local governments, and In-
dian tribes. 

A law, order, or other directive of a 

state, political subdivision of a state, 
or an Indian tribe that designates, lim-
its, or prohibits the use of a rail line 
(other than a rail line owned by a 
state, political subdivision of a state, 
or an Indian tribe) for the transpor-
tation of hazardous materials, includ-
ing, but not limited to, the materials

The following are Munsell notations and 

Commission Internationale de L’Eclairage 
(CIE) coordinates which describe the Office 
of Hazardous Materials Transportation Label 
and Placard Color Tolerance Charts in tables 
1 and 2, and the CIE coordinates for the color 
tolerances specified in table 3. Central colors 

and tolerances described in table 2 approxi-
mate those described in table 1 while allow-
ing for differences in production methods 
and materials used to manufacture labels 
and placards surfaced with printing inks. 
Primarily, the color charts based on table 1 
are for label or placard colors applied as 
opaque coatings such as paint, enamel or 
plastic, whereas color charts based on table 
2 are intended for use with labels and plac-
ards surfaced only with inks. 

For labels printed directly on packaging 

surfaces, table 3 may be used, although com-
pliance with either table 1 or table 2 is suffi-
cient. However, if visual reference indicates 
that the colors of labels printed directly on 
package surfaces are outside the table 1 or 2 
tolerances, a spectrophotometer or other in-
strumentation may be required to insure 
compliance with table 3.
