The US has more oil spills than we thought and the number doubled after production increased six years ago.
8,000 “Significant” Incidents
Richard Stover, PhD, and the Center for Biological Diversity
counted nearly 8,000 significant incidents, between 1986 and 2014, in
records of the pipeline safety administration. By “significant” they
mean causing injury, death, damages exceeding $50,000 in value, a loss
of 5 barrels of highly volatile substances, 50 barrels of other liquids
or there was an explosion. There have been more than 500 human deaths
and 2,300 injuries through-out that period. The number of plant and
animal casualties is much higher.
Though most pipeline failures
occur where there is a long history of development, they occur
through-out the Lower 48. Texas is the worst offender, with 1657
incidents. California had 621 and 48 deaths.
The leading causes of incidents are excavation damages (24.3%), corrosion (18.2%) and equipment failure (17.1%).
After A Pipeline is 20 Years Old
Kristen
Monsell, from the Center for Biological Diversity said the possibility
of a spill “doubles after a pipeline is 20 years old.” In the case of
the recent Santa Barbara spill, for example, “the pipeline was 28 years
old” and had corroded to the point the wall was only 1/16 of a inch
thick.
“Scientists tell us that we will never know how many
animals have been killed (by the Santa Barbara spill) … (Many animals)
will sink to the bottom of the ocean. We’ll likely be seeing the impact
for years and years to come,” said Monsell.
Animal Casualties
“The
day after the oil spill, a report came out that dolphins in the Gulf of
Mexico are still dying as a result of the Deep Horizon spill (in 2010).
When dolphins swim through oil soaked waters, they breath in toxic
fumes from the hydro-carbons. That cause lesions on their lungs and
these animals were dying from lung disease.”
The statistics for Deep Horizon
are numbing: 128 dead or affected dolphins and whales, 1,146 sea
turtles and more than 8,200 birds were collected. There is no tally fish
or plant life. Scientists believe these statistics are only a small
fraction of the actual casualties.
Monsell wonders about some of the aging infrastructure off California’s coast.
