I. Executive Summary

    The Pipeline and Hazardous Materials Safety Administration (PHMSA) 
issues this notice in coordination with the Federal Railroad 
Administration (FRA) to notify the public of four systems that have 
been added to the thermal protection systems list since its most recent 
publication, as well as to solicit comments or updates to information 
on

the current list. The thermal protection systems included on the list 
have passed the pool fire and torch fire tests specified in appendix B 
to 49 CFR part 179 and are acceptable for use, without further test 
verification, on certain U.S. Department of Transportation (DOT) 
specification tank cars. The list is maintained and updated in the 
PHMSA Records Center in accordance with Sec.  179.18.
    The thermal protection systems list was last published in the 
Federal Register on May 13, 1993 (Notice No. 93-12; 58 FR 28436). PHMSA 
is issuing this notice to inform the public of four thermal protection 
systems that have been added to the list since the previous notice was 
published in the Federal Register and to solicit comments or updates to 
the information on the current list. Information updates may include, 
but are not limited to, the following: Company name and location 
changes; material or tradename updates; and information on the use of 
these systems.
    PHMSA is providing a 90-day comment period for responses and will 
publish a future Federal Register notice to address the information 
received and update the list with revisions, if necessary. This notice 
is not a rulemaking action, as it simply provides the rail industry 
with the information necessary to equip DOT specification rail tank 
cars. PHMSA will continue to maintain the list of thermal protection 
systems in the PHMSA Records Center and will also post a copy of the 
list to our website at http://www.phmsa.dot.gov, where future additions 
and revisions will be published.

II. Background

    Thermal protection systems, when required by regulation for DOT 
specification tank cars, must meet the requirements of the Hazardous 
Materials Regulations (HMR). To qualify, the thermal protection system 
must conform to the performance standard and demonstrate such 
compliance through analysis of pool fire and torch fire tests required 
by Sec.  179.18. Thermal protection systems that no longer require 
testing must demonstrate successful testing as specified in appendix B 
to 49 CFR part 179--Procedures for Simulated Pool and Torch-Fire 
Testing. Specifically, the procedures are designed to measure the 
thermal effects of new or untried thermal protection systems and to 
test for system survivability when exposed to pool fire and torch fire 
environments.
     Pool Fire Simulation Test: Must be run for a minimum of 
100 minutes. The thermal protection system covers a specified steel 
plate that meets the requirements of paragraph 2a(2) in appendix B to 
49 CFR part 179. The thermal protection system is exposed to a 
simulated pool fire as specified in appendix B to 49 CFR part 179, and 
it must retard the heat flow to the plate so that none of the 
thermocouples on the non-protected side of the plate indicate a plate 
temperature in excess of 427 [deg]C (800 [deg]F).
     Torch Fire Simulation Test: Must be run for a minimum of 
30 minutes. The thermal protection system covers a specified steel 
plate that meets the requirements of paragraph 3a(2) in appendix B to 
49 CFR part 179. The thermal protection system is exposed to a 
simulated torch fire as specified in appendix B to 49 CFR part 179, and 
it must retard the heat flow to the plate so that none of the 
thermocouples on the backside of the bare plate indicate a plate 
temperature in excess of 427 [deg]C (800[emsp14][deg]F).
    When the HMR require a thermal protection system on a tank car, the 
tank car must have sufficient thermal resistance so that there will be 
no release of any lading within the tank car, except release through 
the pressure release device (Sec.  179.18(a)). Compliance with these 
requirements is verified by analyzing the fire effects on the entire 
surface of the tank car (Sec.  179.18(b)). The analysis must consider 
the fire effects on and heat flux through tank discontinuities, 
protective housings, underframes, metal jackets, insulation, and 
thermal protection. A complete record of each analysis shall be made, 
retained, and--upon request--made available for inspection and 
replication by an authorized representative of DOT.
    DOT maintains a list of thermal protection systems that comply with 
the requirements of appendix B to 49 CFR part 179 and no longer require 
test verification (Sec.  179.18(c)). FRA receives test data from 
manufacturers to validate that the thermal protection systems meet the 
HMR requirements. PHMSA and FRA evaluate the test data to determine 
whether the system is appropriate for inclusion on the list. Once 
accepted, the material characteristics and the information necessary to 
apply any of the systems on this list to DOT specification rail tank 
cars is communicated to the public. This information is available in 
the PHMSA Records Center, Pipeline and Hazardous Materials Safety 
Administration, East Building, 1200 New Jersey Avenue SE, Washington, 
DC 20590-0001.
    The current thermal protection systems list was most recently 
published in the Federal Register on May 13, 1993, in Notice No. 93-12 
(58 FR 28436). To add a thermal protection system to the list, persons 
must provide test data and technical specifications showing that the 
system successfully passes the pool and torch fire tests required by 
appendix B to 49 CFR part 179. This information may be submitted to 
FRA's Hazardous Materials Division, Office of Railroad Safety. See FOR 
FURTHER INFORMATION CONTACT.

III. A List of Thermal Protection Systems Excepted From Test 
Verification

    The two previous lists of thermal protection systems excepted from 
test verification were published in the Federal Register on May 13, 
1993 (58 FR 28436) and January 31, 1986 (51 FR 4063). The current list 
identifies thermal protection systems by their 1993 system application 
number, with the 1986 system application number shown in parentheses, 
if applicable. Furthermore, the four new systems that have been

IV. Revisions to the List of Thermal Protection Systems Excepted From 
Test Verification

    Given that this list was last published in the Federal Register on 
May 13, 1993, (Notice No. 93-12; 58 FR 28436), PHMSA and FRA anticipate 
that changes have inevitably occurred since its most recent 
publication--including the potential that companies on the list have 
moved, changed tradenames, closed, merged with other companies, or have 
been purchased by other companies. Therefore, PHMSA is providing 
stakeholders with the opportunity to comment on and request revisions 
to the current list of thermal protection systems excepted from test 
verification. This notice is not a solicitation for systems not 
identified on the list. Any proposed revisions submitted in response to 
this notice must meet the criteria for revision in this section.
    For revisions to entries on the list:
     Persons requesting only a tradename change must submit 
information that the revision or change is not a new thermal protection 
system. Persons requesting further changes must submit a certification 
statement or test data and technical specifications demonstrating that 
the physical properties of the system have not changed. (See ADDRESSES 
and FOR FURTHER INFORMATION CONTACT.)
    PHMSA and FRA will evaluate the revisions and comments received in 
response to this notice, including review of certification statements, 
test data, and technical specifications demonstrating the system is 
compliance with appendix B to 49 CFR part 179. Once all comments have 
been evaluated, PHMSA will publish a follow-up notice in the Federal 
Register to provide the most up-to-date list of thermal protection 
systems excepted from test verification, including any revised entries. 
PHMSA will continue to maintain the list of thermal protection systems 
in the PHMSA Records Center and will also post a copy of the list to 
our website at http://www.phmsa.dot.gov, where future additions and 
revisions will be published.
