This is part of a continuing a series of blog posts that
will look at the public comments on the DOT’s Pipeline and Hazardous Materials
Safety Administration (PHMSA) notice of proposed rulemaking (NPRM) on high-hazard
flammable trains (HHFT). Earlier posts include:
There were 21 comments submitted in the last three weeks.
There are more than that listed in
the docket, but a number of commenters submitted multiple copies because
they did not realize that their posts were not going to appear in real time.
Even the 21 comment number is a little misleading since there are a couple of
repeats of comments from multiple people, but it is too early to tell if this
is an organized comment campaign (like I have seen from various environmental
groups) at this point.
Most of the comments come from individuals with no direct
connection to the hazmat shipping industry. They are mainly from people that
feel that they are being put at risk from the shipment of crude oil through
their communities. Their comments are generally simplistic, but represent a
very real political reality that this is a problem that has significant
potential impacts beyond the regulated community. Unfortunately, for these
folks the comments are typically their only potential contribution to improving
the safety of the rail lines that pass through their communities. While
simplistic and perhaps poorly informed the comments need to be taken into
account.
There are comments from two people directly connected to the
problem; a railroad
consultant and a freight
locomotive engineer. The engineer calls out three factors that are not
addressed in the NPRM:
• A two person crew should be
mandatory on all trains, especially key trains;
• The engineer's workload should
not increase for safety reasons; and
• A rational amount of buffer cars
on the head end should be mandatory
The consultant identifies a number of interesting points
that have generally been missing from much of the discussion to date. First
off, he reminds us that the DOT 111 cars are not all constructed the same.
Newer models (since the late 1980’s?) are constructed with normalized steel and
are much more resistant to rupture. Second, his list of necessary retrofits for
those normalized steel cars consists of just three improvements:
• Head shields;
• Safety valves; and
• Removable valve handles.
The detailed discussion of the other NPRM safety measures
contained in the consultant’s comments is well worth reading.
In the next week or two we should start to see more in the
way of corporate comments on the rule.
