On March 24, 1989, the oil tanker Exxon Valdez had just entered Alaska's Prince William Sound, after departing the Valdez Marine Terminal full of crude oil. At 12:04 am, the ship struck a reef, tearing open the hull and releasing 11 million gallons of oil into the environment. Initial responses by Exxon and the Alyeska Pipeline Company were insufficient to contain much of the spill, and a storm blew in soon after, spreading the oil widely. Eventually, more than 1,000 miles of coastline were fouled, and hundreds of thousands of animals perished. Exxon ended up paying billions in cleanup costs and fines, and remains tied up in court cases to this day. The captain, Joseph Hazelwood, was acquitted of being intoxicated while at the helm, but convicted on a misdemeanor charge of negligent discharge of oil, fined $50,000, and sentenced to 1,000 hours of community service. Though the oil has mostly disappeared from view, many Alaskan beaches remain polluted to this day, crude oil buried just inches below the surface.

approximately 54 million US gallons (200,000 m3) of oil, of which about 10.8
million US gallons (260,000 bbl; 41,000 m3) were spilled into the Prince
William Sound.
Now getting back to
Chennai, the collision at Kamarajar port, Ennore was reportedly a minor – no
casualty or damage to ships were reported.
But 4 days later, more worrying
reports are emerging. Some media reports
suggest that failure of Kamarajar Port (Ennore) to raise an alarm over the
enormity of the oil spill on Saturday may have contributed to the sluggish
start in clean-up operations. Days since
the collision, it is stated in some quarters that about 40 tonnes of oil may have leaked from
Dawn Kanchipuram after the accident.
A report in today’s Indian
Express estimates that more than 20 tonnes of oil spilled from MT Dawn
Kanchipuram, which is owned by Mumbai-based Arya Voyagers as against the
initial report of two-three tonnes by the ship,” citing a spokesperson of the
Coast Guard. During the impact of the collision, the cofferdam tank in the ship
which was carrying the bunker oil was ruptured. The Coast Guard were led to
believe, on the basis of information provided, that they were battling a minor
spill, which could be contained within 24 hours. Marine Mercantile Department
clarified that a cheap-grade oil was purchased by the vessel to cut costs.
Sources said the thickness of the cheap grade oil has made it difficult to
contain the spill by the containment boom resulting in the oil spreading over
31 km from Kamarajar Port in Ennore to Adyar Creek.
Currently, the Coast Guard
along with State government officials are mopping up the coast. Till now,
approximately 15 tonnes of oil and sludge have been collected. Various resource
agencies from Tamil Nadu Pollution Control Board, State Fire Service, Kamrajar
and Chennai Port, Coastal Security group,
Tree Foundation with more than 200 volunteers from several NGOs are
participating in the clean-up. It is
stated that major per cent of the oil slick is towards the northern side of
Chennai Harbour near RK Kuppam Beach. North of Chennai Harbour, 800 metres of
shoreline in approximately 11 locations have been affected with thick oil
sludge washing ashore. Some cleaning is
happening at Marina beach as well. The
Coast Guard ship ICGS Varad sprayed two tonnes of OSD on Tuesday mid-sea after
carrying out an aerial survey. Kamarajar Port continues to maintain that there
has been no oil spill since Saturday morning after it had laid oil booms to
contain the spread of spilled oil.
