Oil
Spill in the Komi Republic
-
by Donald E. Koehler, CRP
Learning from
another countrys disasters may provide lessons to North American
disaster planners today. A case in point - From August to September
1994, a series of massive oil pipeline leaks occurred in rural Northern
Russia, nearly on the Arctic Circle. The nearest town to the major spill
location was Usinsk, just 30 Km from the nearest spill area. The impact
from the spills and outcomes of the resultant containment, cleanup and
mitigation activities may be of interest and provide information for
Disaster Recovery Journal readers -both for the lessons learned and
for use in future planning. While the Russian pipeline leak may be unique
for its sheer size - it provides North American agencies many examples
and lessons. Smaller pipeline leaks occur regularly in North America,
a response planner or provider must understand this type of technology
accident.
What happened?
The oil spill, known as The Usinsk Accident has been reported
as one of the worst in history, up to eight times greater than the EXXON
VALDEZ. Only the 1991 post-war cleanup in the Middle East posed greater
problems. In the KOMI spill, the local pipeline owner, KomiNeft (Komi
Oil), local authorities and the Russian government initially tried to
hide or obscure the extent of the spill. When oil appeared in the Barents
Sea, the world community was forced to step in to control the extent
of potential environmental damage.
The KOMI oil release has been estimated as high as 200,000 metric tons
of oil, found at four major points over an 18 Km length of older pipeline.
The pipeline, first placed in service in the early 70s, had been leaking
for some time, with major leaks first noted as early as 1988. Corrosion
caused by oxygenated river water, which is mixed into the oil to assist
in pumping, was deemed a major factor in the deterioration of the pipeline.
Take the old Soviet environmental attitude, bad construction techniques
and materials, then add the general societal chaos at the collapse of
the old Communist system and you have a complete recipe for a ecological
disaster.
Initial containment efforts, such as siphon dams built of sand, were
poorly engineered and built and when the spring thaw hit in 1995, failed
completely. Under increasing intense pressure from the world community,
western technology and a very small number of American oil spill response
workers were brought in under contract to provide both new cleanup technology
and training on proven response techniques. The US Government and World
Bank were active in addressing the spill by providing both funding and
survey data.
Finally, to give you a better feel for the size of this event, the spill
was large enough to be visible from space.
For more details visit the Internet, see the URLs found at the end of
this article for some excellent sites.
How did I get involved? Before the spill, I had spent several years
writing response, training and logistics support documents under contract,
then later working for, an environmental company in Alaska. In April
1995 I was contacted by the company owner and offered a job on the spill
response team as the plan writer and to provide photographic documentation.
I resigned my position at the University of Alaska and traveled to Usinsk.
Once at the job site, the required skill set turned out to be much more,
with making maps, fixing gas samplers, setting up computers and printers
and basic survey work as part of the total response effort. I found
the challenge enjoyable.
Walking some 40 Km, I followed the soiled shores of the Kolva river
and feeder streams, the inland spill sites and the length of the damaged
section of the pipeline - photographing & surveying the damage.
It is impossible to find words to fully describe the spill and the resultant
impact to the tigara forest. I photographed the project, people, equipment
and structures - producing over 3,000 map-indexed images. A project
ecological science team on site generated additional index-photo work
and documentation. Communication was provided by radios and reporters
obtained from a Canadian oil company under a sub-contract. Some of the
initial on site communication back to Alaska was via IMARSAT p-phone
- these units really are worth their weight in gold for this type of
operation - especially during the logistics ramp up.
The Kolva River Basin Response Project was deemed successful in as much
it prevented further oil from reaching the Kolva, Usa and downstream
rivers. Funds available and used for the project were on the order of
20 to 23 million USD, with the bulk of the project work done in two
summers. The EXXON VALDEZ cleanup, in contrast, consumed some five thousand
million (5Bn) US dollars over several years. The impact site in Alaska
was larger by several orders of magnitude. The disparity in response
funding levels reflects differences in government philosophy, location,
physical and chemical characteristics of the oil itself and - frankly,
the depth of the pockets of the pipeline company. Since KomiNeft was
in technical bankruptcy at the time, funding was heavily dependent on
sources outside of Russia. By the time I had arrived KomiNeft workers
had been paid in script for over a year.
Terrestrial crude oil spills can be viewed as easier to access and control,
with less impact from bad weather or access, compared to ocean tanker
spills. On a spill of this size and located in the northern wilderness,
nothing was easy. Temporary roads were laid out to the spill sites for
construction of containment and collection infrastructure. In many cases
the spill containment and cleanup cause at least as much damage as the
initial oil contamination.
In the KOMI cleanup, large amounts of the oil was simply buried in polygons
- large clay lined pits near major collection points. The realistic
aim of the project was to keep the oil from migrating into the ocean.
Management was done site by site with supervision provided locally.
The radio net was used primarily for safety and logistics calls.
I would note, that while the oil was bad for the environment, the larger
impact to the fragile Arctic ecology may have been the weak brine mixed
with the oil to ease pumping. The oil itself is a thick, heavy (high
paraffin) type which must be heated to pump. Once the oil left the broken
pipeline, it essentially froze in place - looking for all the world
like huge slabs of black candle wax. Indeed, in many areas the oil was
removed by backhoe. The summer heat would cause it to flow and many
areas water from seasonal snow melt had carried oil high into the trees
lining the impacted streams.
Impacts to the local area.
The area of the spill was both remote, thinly populated and very rural,
in many ways like conditions found in much of Alaska. The initial spill
reported called out an impact on some 67.5 hectares of tundra, then
spring melt waters spread the oil. Scientists have established that,
in total, about 2,110 hectares (1 hectare = 2.2 acres) of meadows and
pastures, including reindeer grazing lands, were contaminated and in
some villages up to 92% of all the grazing and fodder producing land
was affected. Damage to rivers, pastures and meadows still seriously
affects the well-being of the local residents who depend strongly on
their vegetable plots, cattle, hunting and fishing for existence.
The economic impact and damage estimates were based on the officially
adopted figure of 14,033 tons of oil. Overall damage was estimated at
more than 311 billion Rubles (about 103 million USD). The officially
confirmed estimation of 79,000 tons of spilled oil brings the cost of
the damage to well over1.5 trillion Rubles (495.7 billion USD).
The difference in estimate size of spill , from under 15K tons to the
high end of 102K to 200K tons, is the difference between Russian, KOMI
official estimates and measurements made by the US EPA and Canadian
environmental specialists.
In contrast, the TransAlaska Pipeline System (TAPS) has operated during
the same time frame as the KomiNeft system in a similar environment
with small spills, measured in barrels rather than tons. Both were quickly
contained, cleaned up and restoration work initiated. Strict oversight
and regulation provide the difference in the outcome.
Of interest to disaster planners and response
teams.
Not all pipelines
carry oil or natural gas. Pipelines that carry oil may also carry associated
hydrocarbon products. Gas pipelines may carry a wide range of products.
Communication is a prime worry in response and containment activities.
Response planners must account for the inevitable EMI/RFI and incompatibility
issues that arise from too many radios and too few frequencies. Work
in or around littoral or coastal areas brings the additional headache
of coordinating marine and safety frequency usage. Pre-planning and
drills in your area of responsibility will help - but you must experience
the incredible congestion to fully understand the frustration of users.
In addition, you need to plan for:
1. The sheer number of people who respond for containment, cleanup and
mitigation activities. You may not be able to find a hotel/motel room
for miles around your site. The rental car scene will be chaotic as
will any public transportation systems. This has been described as a
flood of humanity - in the Russian example, several thousand
people showed at the gate of the project office seeking jobs. In the
Alaskan spill response, US Navy ships were moored in the area to provide
housing and meals.
2. Resource allocations and security. You may find yourself competing
with deep pocket Government agencies or pipeline response companies
for scarce resources. As silly as it may sound now -- do you have enough
batteries, generators and the like for operation of at least a week
at the response site? I hate to sound overly sensitive about logistics,
but it is a hard lesson to learn. In Russia, for example, many of my
American colleagues learned the hard way that you dont just go
to the corner store for supplies. If you dont have it when you
leave, you dont have it.
3. Strap-hangers - the press, protesters, job seekers and
the idle curious may play into this equation as well. How good is your
security? The possibility of injury to overly curious tourists cannot
be overemphasized. These same folk pose a problem with spreading pollution
beyond the initial impact area or back into cleared areas.
4. Downwind impacts. Using the Russian example - a large oil containment
area was deliberately and illegally, set alight. The smoke plume (and
toxic byproducts) went up over 8,000 feet and extended beyond the horizon
- some 40 miles away. Your workers will be required to wear Personal
Protective Equipment if they will be near the spilled product. Be sure
to have an initial issue on hand before you leave for the response site.
5. Transportation impacts. Large numbers of vehicles - from pickup trucks
to 10 yard dumpers and backhoes - and associated flatbed and tanker
trucks may become an obstacle and cause a logistics nightmare. Do you
have alternate transportation routes or bus service available for your
workers? A park and ride scheme may be one way to beat this problem.
6. Health impacts. Toxic byproducts from spills or burning of spilled
material may cause health impacts. You most likely will have to start
some type of employee health monitoring if you have folks on site for
extended periods of time. See your local OSHA or EPA representatives
for the current rules and regulations.
