This is part of a continuing look at the recently published
final rule on highly-hazardous flammable trains (HHFT; HM-251). Earlier posts
in the series include
In this post I will be looking at the new requirements that
the offeror of crude oil has for the characterization of that material. Even
though there are already requirements in the hazardous material regulations to properly
classify hazardous materials for shipment, PHMSA is adding a new section that
specifically addresses additional measures that a shipper of crude oil must
take.
Current Requirements
There is a lengthy discussion in the preamble concerning the
current
requirements for classifying hazardous materials. In general 49
CFR 173.22 requires the offeror to properly “class and describe a hazardous
material in accordance with parts 172 and 173 of the HMR.” There is no specific
mention of how often the testing has to be done to achieve that objective, just
that the testing needs to have been done.
NPRM Proposal
In the NPRM PHMSA proposed adding a new §173.41 that would
outline new testing requirements for mined gasses and
liquids. The justification was that, while most hazardous materials shipped
by rail were manufactured product with some level of consistency of characteristics,
crude oil was taken from the earth and the specific characteristics varied not
only by the location of extraction, but could vary by the time of year or
extraction technique employed.
The NPRM proposal would have required the following areas to be addressed
by the offeror:
∙ Frequency of sampling and testing;
∙ Sampling at various points along
the supply chain
∙ Sampling methods;
∙ Testing methods;
∙ Statistical justification for
sample frequencies;
∙ Duplicate samples for quality
assurance purposes; and
∙ Criteria for modifying the sampling and testing
program.
There is a lengthy discussion
in the preamble about the large number (65,000+) public comments made about these
crude oil characterization requirements and the PHMSA responses to those
comments.
API RP 3000
One of the specific areas in that discussion that has an
important bearing on the testing of crude oil is the new document from the
American Petroleum Institute; API
Recommended Practice 3000, Classifying and Loading of Crude Oil into
Rail Tank Cars. This document
obtained its final approval after the end of the comment period for the NPRM,
so PHMSA was not able to include an intent to incorporate this standard by
reference.
PHMSA did note in
their preamble
discussion that:
“The one area where the concerned public, environmental groups, and
industry stakeholders agreed was that API RP 3000 should be adopted or
permitted as a method of compliance with the proposed requirements.”
PHMSA does explain that:
“Furthermore, the boiling point
test specified in the API RP 3000 does not align with the requirements
currently authorized in the HMR. Shippers must continue to use the testing
methods for classification of flammable liquids outlined in § 173.120 and
flammable gases in § 173.115. However, API RP 3000 is otherwise consistent with
the sampling program requirements in paragraph 173.41(a)(1)-(6) and may be used
to satisfy these adopted sampling provisions.”
Finally, PHMSA notes in the final paragraph of the
discussion of characterization that: “It should be noted that PHMSA may
consider the adoption of the non-codified testing provisions of API RP 3000 in
a future rulemaking.”
Changes in §173.41
In general the NPRM version of §173.41 pretty much made it into the final rule.
There were some changes. First, of course, is that the term ‘mined gasses and liquids’
was changed to
a slightly more restrictive ‘unrefined petroleum-based products’. The term ‘classification’
has also been removed with PHMSA clarifying the related
requirement for the sampling and testing program to include a
requirement to “identify properties relevant to the selection of packaging
through testing or other appropriate means”.
PHMSA is also clarifying
§173.41(a)(1) to specify that the program must account for “any appreciable
variability of the material” with a list of recommended factors. They are
also amending § 173.41(a)(3) to replace “as packaged” with “as offered” to
clarify that the sampling may occur before the crude oil has been loaded into a
transport vehicle.
Summary of §173.41
The following summary is taken directly
from the final rule. Links have been added to the actual language of the
appropriate portion of the added language:
“In this final rule, we are adding
a new section 173.41
prescribing a sampling and testing program for unrefined petroleum-based
products. This section specifies what must be included in a sampling and
testing program in paragraph
(a). Paragraph
(b) of this section requires shippers to certify that unrefined
petroleum-based products are offered in accordance with this subchapter, to
include the requirements prescribed in paragraph (a). Paragraph (c)
provides the requirements for documentation, retention, review and
dissemination of the sampling and testing program. Finally, paragraph (d) of
this section states that each person required to develop a sampling and testing
program make the documentation available upon request to an authorized official
of the Department of Transportation.”
