Rethinking Oil-Spill Response
In RESTCo’s work on self-sufficiency for remote communities, we
have put considerable work into researching the current energy paradigm,
particularly with a view to reducing dependence on external sources,
the climate change impact of energy infrastructure choices, and the
impact of current practices.
One result of this work is an increased awareness of the consequences of
oil spills, and how common small spills are (daily occurrence), as well as
of the need to combat major spill events (e.g., in 2014 Southern Star VII,
Trans-Israel pipeline spill, Mid-Valley pipeline spill, Houston Ship
Channel collision spill; in 2013, North Dakota train collision, North Dakota
pipeline spill, Lac-Mégantic train explosion/fire/spills, Mayflower
Arkansas pipeline rupture, Magnolia refinery spill, and so on from the
Pennsylvania 'gusher' spills before 1900, and
including 2010 Deepwater Horizon and 2010 Kalamazoo pipeline rupture which are
still far from cleaned up or remediated).
RESTCo benefits from the particular knowledge of one of our principals, who
worked on oil spill science research in the Beaufort Sea area in the 1970s,
and has a continuing interest in the topic (currently working on relevant ISO standards
in this area).
RESTCo has devoted a lot of time and effort to this subject area since 2010
(when we incorporated), and our principals had already worked the subject prior.
In 2011, RESTCo was an intervener in the Canadian National Energy Board hearing
related to offshore oil and gas drilling in the Arctic. RESTCo sponsored and
hosted the Ottawa Forum
in September 2011 to discuss scenarios, approaches and technologies related to
oil spills and response plans. It was a valuable experience, when we determined
that supposition and mythology greatly outweigh science and evidence in
regulatory and media conversations on the subject. The industry track record on
oil-spill recovery and remediation is uniformly awful, being based on decades-old
technology and outmoded approaches. While small spills are daily occurrences
everywhere in the industrialized world, major spills are rare events with
substantial consequences, akin to house-fires on the probability vs. consequences
From RESTCo's perspective, typical response approaches at both ends of the
scale rate as failures.
In the case of frequent, small spills, the standard approach is to use an
absorbent (sawdust, kitty-litter, one-use industrial absorbent pads, powder sponge),
to soak up the liquid as best one can, shovel the mixture into a temporary
transport container, and take it to a toxic waste site for disposal.
In the end, the leaked material of value and the absorbent are rendered into a
larger mass of toxic waste, which remains a health and physical hazard until
it is permanently disposed of (usually buried) at a special waste management site.
In the case of large infrequent spills, the industry's standard approach
requires a time-consuming evaluation of the event, then equipment is diverted from other duties,
reconfigured, moved to one of a very limited number of main response bases,
loaded, and then deployed to the spill site. This approach typically takes days, sometimes weeks,
by which time the spill response area has grown geometrically with each passing
hour, and may have generated secondary events (e.g., evacuations like that in Mayflower Arkansas)
or massive multi-zone spill areas (like the Macondo blowout with oil in the water
column above the leak site, surface oil spreading in all directions, and shore-line
oil contact). Macondo occurred in the U.S. oil industry’s front yard,
in warm weather conditions, and made mainstream media headlines within minutes of the
event due to the explosion, fire, loss of lives and injuries. It still took days
to mount even the initial token spill response. At Kalamazoo, the
pipeline company took 14 hours to recognize a major rupture and spill event had
occurred, and only noticed then because an individual - not associated with the
company - notified them of the problem.
The oil and gas industry universally says it embraces a ‘safety culture’.
Many independent observers say that its track record does not bear this out, and
examination of the Macondo event has led courts to find that BP was negligent in its
operations, which is at the opposite end of the spectrum from a ‘safety culture’.
RESTCo does not have the resources to make major strides in the area of spill
prevention and detection by the oil majors, but we thought we could contribute
in the area of creating an effective spill response methodology.
(RESTCo is currently contributing to international standards work related to spill
detection and monitoring. To date, our contributions to spill prevention have
RESTCO's approach to the issue is markedly different from that of the oil industry,
because we start by examining the consequences and measuring the
performance of the response effort from a holistic economic and environmental
perspective. (There’s no market for the oil if we kill off all the humans.)
RESTCo is not against the use of oil. We are opposed to profligate waste of
valuable resources, and poisoning of our shared environment. Oil spills are both
wasteful and damaging to our environment.
For at least four decades, oil industry's spill response has boiled
down to saying "this is the technology we developed in the 1960s to respond to
oil spills on water, and we have learned how to use it for maximum effectiveness
since then". The primary tool set consists of booms and scooping; accelerants to burn the
slicks (as weathered oil typically will not ignite on its own);
and chemicals. Sadly, even after over 40 years experience, the outcomes
are not acceptable. In many cases, the strategy is still to ignore spills on
open water, only addressing them when the slicks reach shore.
Spills on land are almost always treated as 'mop-up' operations, generating
masses of solid, wet toxic waste, occasionally with land remediation following.
RESTCo has reached a number of conclusions as a result of its research and work
in the area of oil spill response. The industry talks of response and remediation,
but does not effectively address the idea of recovery. If the spilled crude oil product can be
recovered quickly - before the volatiles evaporate - the quality of the recovered product could
be high enough to be used as refinery-grade input. This is in marked
contrast to conventional industry practice, in the best case scenario for an oil-spill
event at sea, no significant
pick-up capability is put on-scene for at least 72 hours.
Full responsibility for oil-spill prevention or stopping a spill must remain with
the operator. However, as operators and carriers have generally abdicated or
contracted out oil-spill response and ignored remediation - especially when the
impact moves beyond their property - we feel the call to improve the practice related
to oil-spill response, recovery and remediation.
Large oil spill events require a ‘fire-department’ response mentality, while small
spills may be addressed with a 'fire-extingusher' mind-set. Existing
first-responders - frequently volunteer fire-fighters - need training,
support, and appropriate equipment and materials from the moment the alarm sounds.
Locals will respond first, simply due to geography and transit time - and because
of anchored vested interest - this is where they live. An effective response plan
has to take local response into account.
The second-level responders need to show up with appropriate equipment within a very short period (hours at
most) for oil recovery and spill containment so that the incident zone does not
continue to expand exponentially. Once the immediate recovery and clean-up
has been completed, incident management should move to remediation within days
to reduce the impact on local organisms.
Conventional containment booms are not effective in icy water, or where there
is any significant degree of wave action. Booms are a finger in the dike, not a
Current conventional oil skimmers are not effective at sea, where off-shore
oil rigs are located and many ship-related spills occur. Recovery rates are typically in the
order of 3-5% in warm, calm waters. Test results higher than this are
typically based on thick layers of oil in a test tank, unlike real-world
conditions where oil has spread to form a thin film on the effectively infinite ocean.
Chemical dispersants like Corexit (used at Macondo), designed
to remove oil from the water surface, constitute chemical warfare.
They cause collateral damage by decimating any living organisms
which encounter the oil-dispersant mix, which is
at least 50 times
more toxic (neurotoxin) than the oil alone. The science on this, based on results, still coming
in from the unauthorized Macondo Corexit experiment, is sufficiently alarming
number of countries have banned Corexit (e.g., UK, Denmark, Sweden) and
ordered existing stockpiles destroyed.

Heavy oils (e.g., bitumen after the diluents have evaporated) probably won’t
reach shore. Instead, in open water, after a day or two, they become denser
than water as the lighter volatiles dissipate and wave action exposes the tarry
surfaces to sediments.
Canadian federal government and
other testing has consistently demonstrated this behaviour for dilbit (bitumen mixed
with diluents required for it to flow in pipelines or be put into tankers) spilled
in water. So waiting for the heavy oil to reach shore is a futile approach; bereft of
the lighter volatile components, the oil-tar will be deposited on the floor of the water body, potentially
creating the equivalent of an asphalt roof on it and whatever was living on it.
Think of it as paving the seafloor.
In situ burning consists of pouring accelerants (something like gasoline or barbecue
starter fluid) onto a spill, and then setting the lot on fire. This is something akin
to dealing with the autumn’s fallen leaves in the woods by setting the forest on fire.
The result is black smoke thrown into the atmosphere,
accompanied by a massive emission of carbon dioxide and a whole lot of heat. In a
world where we need to reduce emission of greenhouse gases, waste heat and darkening of
the planet surface from soot, this approach is 180 degrees in the wrong direction. Turning
water pollution into greenhouse gases, air pollution and soil contamination is not a
solution, just a transformation to a bigger set of problems.
In short, when it comes to oil-spill response today, conventional practice is largely
wrong in terms of response approach, techniques and equipment used, and an inflexible
oil industry. What is worse is that the threat of oil spills is growing as the
infrastructure is aging and we are going after harder-to-access reserves ('extreme oil').

Another take on the growing risk from aging oil infrastructure.
Amphibious capability is a must-have for effective spill response. Spills
on land, if left to the whims of gravity and of sufficient volume, will run to lower
ground; most often, water or wetlands. Oil spilled on water will drift until it
reaches shore (or sinks to the river bottom or seabed). Current oil spill response
equipment does not embrace amphibious technology.
RESTCo has an approach, and has developed a suite of techniques, tools, technologies,
and network of affiliated organizations, which can do better.
The following are some of RESTCo's accomplishments related to oil spill technology,
mitigation and response.

RESTCo's submission to the UK House of Lords Select Committee
RESTCo's invited submission to the U.S. National Research Council
The U.S. Bureau of Safety and Environmental Enforcement (BSEE) invited RESTCo to submit a
proposal for an oil spill response solution in 2014.
Unfortunately, the funding set by BSEE for the proposal was not sufficient to cover the cost of
developing a vessel on the scale they required. In early 2015, a similar call for proposals was
issued by BSEE, and RESTCo submitted a
white paper in response. Following that, BSEE requested a full technical
and pricing proposal from RESTCo related to recovering oil from the water surface where ice is
present. After spending months evaluating our
BSEE determined it had merit, but due to budget constraints, did not award a contract to
pursue the work (December 2015).
RESTCo completed the construction of its own mobile oil spill response
test tank and monitoring facility during the first half of 2015.
