oil spill

In this article, Raghav Ajmera of Shri Navalmal Firodia Law College, Pune discusses Oil leaks in the sea and environmental damage – Indian laws that are relevant.

Introduction

Oil leaks or oil spill is considered among the worst ecological disasters. The most transported commodity in the world is oil and because of its chemical nature, it is transported through the medium of the sea. These type of spills occurs when there is a collision of vessels carrying oil cargo. Oil spills not only pollute the sea but the whole environment. It is a nation and international concern regarding the marine pollution because when the spill occurs it is not a short-term pollution it is a long-term pollution. The spills last for decades and it cannot be cured until and unless the appropriate measures are taken to prevent, control and remove the risk.

Environmental Pollution and its types

Pollution refers to the addition of harmful or contaminants to the natural environment is known as pollution. Pollution is of many types which areas :

  • Air pollution: The harmful particles or contaminants released by the industries or the vehicles into the natural environment causing the problem to respirate is known as air pollution.
  • Noise pollution: The sound created by the industries, airplane, vehicles which can cause a hearing problem. It affects both health and body.
  • Water pollution: The harmful intoxicants or the waste released into the water which may harm the groundwater is known as water pollution.
  • Soil pollution: When the harmful chemicals are released by the spills or underground leakage into the soil is known as soil pollution.

Meaning of Oil Spill

In the basic terms, it refers to when the oil is released into the sea or oceans or coastal areas due to the collision of two vessels carrying oil cargo. It has a direct effect on marine ecosystem just because of the inhuman activity and it is also a kind of pollution. It is the release of liquid petroleum hydrocarbon. Oil spills have effects on society economically, environmentally and socially. The quantities in which the spills have taken place is between several thousand tons to several lakh tons. Oil spills result in the damage of the beaches, marshlands, marine mammals, fish, and birds. Spills may take from days to years of cleaning.

Environmental damages by oil spill

An oil slick is the floating of oil over the water after the oil spill and when an oil slick reaches the beach the oil grasp to every rock and grain of sand present there at the beach. If the oil spill reaches to the forest or other wetlands the grasses there absorbs the oil which can damage the plant and make the whole place an unsuitable habitat.

When the oil stops floating on the surface and sinks into the water it has the same effect to the marine ecosystem which leads to the killing of the fishes inside the water and thus resulting in the breaking of the food chain from which the world is connected.

According to the reports, despite the efforts of cleaning up after the Exxon Valdez oil spill in 1989 a study of 2007 conducted by the National Oceanic and atmospheric administration(NOAA) found that 26000 gallons of oil from the Exxon Valdez oil spill was still found in the sand along the Alaska shoreline that is why it is regarded as the most dangerous environmental disaster which cannot be removed even after years. The scientists also revealed that the oil was declining less than 4 percent rate annually.

  • Oil spills kill birds

These are the kind of birds which swim and dive for their food and are most likely to be damaged by the oil spill. Even the small amount of oil can cause danger to the bird. By the coating of oil over the birds not make them able to fly and thus destroying their natural waterproofing.
As per the reports, Exxon Valdez oil spill killed approximately between 2,50,000 to 5,00,000 seabirds and also a number of shorebirds.

  • Oil spills kill marine mammals

Whenever the oil stops floating and gets started to sink into the marine ecosystem it causes a problem for the dolphins and whales as the oil reaches down there it creates a problem for the animals to breathe. Even when the marine mammals sense danger during the time of oil spill and leaves the place makes them safe but it causes a problem of food as their whole habitat is dependent on the marine fishes which are exposed to the oil spills which may be poisoned by the oil.

  • Oil spills kill fish

The oil spills cause a big danger to the marine fishes which causes their death as they are exposed to a large quantity of oil spill.

  • Wildlife habitat and breeding grounds – Oil spill

It has long-term effects on every kind of environment not only the marine environment. The oil spills destroy the natural habitat of the seaside animals like sea turtles who spend most of their time in the sea but comes ashore to nest. Sea turtles can be exposed to the oil spill as they stay ashore for the nest and when the oil floats over to beaches it destroys the eggs which cause a problem in their development.

The danger the oil spill has varied due to different factors including the amount of oil spilled, the time, the location, the type and weight of oil spill but at the end, every oil spill is a danger to the environment.

International conventions

There are international conventions which are made for the prevention of pollution from the ships and these are directed towards the following objectives :

  1. The first objective is to provide the complete elimination of international pollution of the seas by the oil;
  2. To provide for the minimization of the international and accidental pollution of the seas by oil and other elements by the help of offshore facilities;
  3. To provide for the complete elimination of the pollution of the seas by activities such as tank washing and bilge discharge involving noxious and hazardous cargoes other than oil;
  4. To deal with the minimization of the oil spill by the result of accident;
  5. To deal with the dumping and the other disposal waste of ashore and sewage by the ships into the seas;
  6. To deal with safe carriage of dangerous goods;
  7. To deal with air pollution generated from ships.

In order to deal with the problem arising out of the sea oil pollution, there have been following three conventions :

  1. International Convention relating to intervention on the high seas in Cases of Oil Pollution Damage, 1969;
  2. International Convention on Civil Liability for Oil Pollution, 1969, and
  3. International Convention on the Establishment of an International Fund for Oil Pollution Damage, 1971.

Merchant shipping Act, 1958 – Where to complaint and how to complaint

The part XI of the Merchant shipping act, 1958 gives effects to international conventions regarding the prevention of pollution of the seas by oil. The problem of oil pollution is a very big concern to our country as oil is imported to our country in large quantity.
