Committee on Government Operations

Abstract:
We appreciate the opportunity to testify as the Subcommittee begins
its oversight into the tragic California train derailment that spilled
about 20,000 gallons of metam sodium (weedkiller and pesticide) into the
Sacramento River. While the ultimate damage will become clearer over
time, this spill could pose a threat to the region's major water supply
and may result in long-term destruction of valuable scenic and recreational
resources.
On July 17, 1991, your Subcommittee asked us to review several issues
concerning federal regulation of hazardous materials transportation and
the circumstances surrounding this particular accident. Much work
needs to be completed before your various questions can be answered.
However, we can discuss the information we have obtained thus far about
the accident. I would like to caution that the information we are
providing today regarding the July 14, 1991 accident is preliminary and
is based on interviews with various officials including those of the Federal
Railroad Administration (FRA), the Research and Special Programs Administration
(RSPA), the Environmental Protection Agency (EPA), and the National Transportation
Safety Board (NTSB).
In summary, regarding the accident we found:
-
The actual cause(s) of the accident will not be known for some time.
However, there is a question about whether the train may have been underpowered
for the region's terrain. The derailed train weighed 4,292 tons and
did not have a separated "pusher" locomotive. Since the accident,
Southern Pacific (SP) has changed its operating practice to limit train
tonnage to 3,200 tons.
-
Metam sodium that spilled and caused the damage was not classified by either
EPA or RSPA as hazardous. However, the U.S. Coast Guard, which regulates
transportation of hazardous materials on water, classifies metam sodium
as a hazardous material when shipped in liquid bulk form. Coast Guard
officials told us the substance is in the worst class of marine pollutants
because it is highly toxic to marine life. RSPA's Acting Administrator
told us that RSPA relies exclusively on EPA to identify those hazardous
substances which should be regulated as hazardous materials when transported
in commerce. Regardless of EPA's designation, we believe that the
Secretary of Transportation has independent authority under the Hazardous
Materials Transportation Act of 1974 (HAZMAT Act) to designate metam sodium
as a hazardous material.
-
We do not know when the first response teams arrived on the scene and whether
the response time would have been quicker if metam sodium had been classified
as hazardous. Conceivably, officials might have responded faster
if the material had been labeled hazardous. Also, we do not know
whether less damage would have occurred if response time had been quicker
because it is unknown how long it took the metam sodium to spill from the
car.
We will also discuss a number of reviews we have conducted over the last
few years relating to FRA safety programs and certain RSPA activities.
Inspections of railroads and enforcement of laws, rules, and regulations
are key to safe railroad operations. We found weaknesses in FRA's
railroad inspection and enforcement activities and FRA has agreed to make
major improvements based on our recommendations.
We have also found that a number of provisions of the 1990 Hazardous
Materials Uniform Safety Act have not yet been implemented.
