Oil Spills? Accidental
petroleum release into environment
70% are oil transportation leakages
Lasting Detrimental effects
Santa Barbara Oil Spill January, 29, 1969 80,000 to 100,000
barrels of oil Detrimental effects
to the environment Gave birth to a
movement Biggest that
California has seen
Where? 6 miles(10Km) from
the coast of Union Oil Platform A
Only 14 minutes for oil to show
800 mile square area.
Oil coated 35 mile of coastline
How? Dug 3500 feet for oil “mud” used to maintain
pressure became dangerously low
Initially successful but later devastating
Created five break points for leakage
Not Meeting Safety Regulations
Ecological Impact Incoming tides were
filled with corpses Clogged blowholes
causing hemorrhages
Poisoning by oil Migration route
disturbed Seabirds
Funny Quotes “
I don't like to call it a disaster, because there has been no loss of human life. I am amazed at the publicity for the loss of a few birds.”
"This is just Mother Earth letting the oil come out."
--Fred Hartley, President and CEO of Union OIl
Clean Up Efforts Joint Community work 11.5 days to control
leakage Cement plug Scooped up oil,
dumped detergents on tar, and straw used to soak oil
Rocks steamed to be cleaned
Consequences Policy Revisions
New laws Economic effects
Fishing Industry Environmental
effects Fish Population Birds
Aftermath Major impulse to
the environmental movement
GOO (Get Oil Out) was born
Laws on offshore drilling
Short lived
Exxon Valdez Oil Spill Prince William Sound,
Alaska Collision with Bligh
Reef 260,000 to 750,000

sea birds, 2,800 otters, 12 river otters, 300 harbor seals, 247 bald eagles, and 22 orcas ,
Killed tons of planktons Reproduction rate
decreased Death rates increased
Clean Up Only 16 % of the
shoreline was cleaned
Dispersants released
Physical removal of oil and tar
Bioremediation Winter storms
Change in ExxonMobil Spent over $4.3
billion dollars Modified tanker
routes Drug & alcohol testing Extensive & more
periodic assessment of vessels
Strengthened training programs
