What’s an oil spill?
•Happen when people make mistakes or are careless and cause an oil tanker to leak oil into the ocean.
•If the equipment breaks down, the tanker may get stuck on shallow land. When they start to drive the tanker again, they can put a hole in the tanker causing it to leak oil.
•Illegal dumpers dump crude oil into the oceans because they do not want to spend money on decomposing their waste oil.
•Natural disasters (like hurricanes) may cause an oil spill. If a hurricane was a couple of miles away, the winds from the hurricane could cause the oil tanker to flip over, pouring oil out.
WHAT EFFECTS DO OIL SPILLS HAVE?MARINE LIFE MARINE ECOSYSTEMS
(benthic organisms, fish, sea birds) (marshes, mangroves, corals)

PHASES OF DISASTER MANAGEMENT
Response: includes actions taken to save lives and prevent property damage, and to preserve the environment during emergencies or disasters. The response phase is the implementation of action
plans.
Recovery: includes actions that assist a community to return to a sense of
normalcy after a disaster.
Mitigation: any activity that reduces either the chance of a hazard taking
place or a hazard turning into disaster.
Risk reduction: anticipatory measures and actions that seek to avoid future
risks as a result of a disaster.
Prevention: avoiding a disaster even at the eleventh hour.
Preparedness: plans or preparations made to save lives or property, and help the response and rescue service operations. This phase covers implementation/operation, early warning systems and capacity building so the population will react appropriately
when an early warning is issued.
• International Convention on Oil Pollution Preparedness, Response and Co-operation (OPRC) adopted by IMO (International Maritime Organization)• Promulgated in 1995• India accepted OPRC on promulgation
OPRC CONVENTION PROVISIONS:• Designation of the competent national authority.• National operational contact point for receipt of oil pollution reports.• An authority to act on behalf of the state.• A national contingency plan for preparedness and response.• A minimum level of pre-positioned oil combating equipment commensurate with risk involved.• Exercises for oil pollution response & training of relevant personnel.• Detailed plans & communication capabilities for responding to oil pollution incidents.• Up gradation of data in regional & local contingency plan with up-to-date information.• Risk assessment & first response capabilities accordingly by industries & ports.
MARINE ENVIRONMENT PROTECTION: A BACKGROUND
NATIONAL OIL SPILL DISASTER CONTINGENCY PLAN (NOS-DCP)
• India promulgated NOS – DCP in the year 1996.• Approved by Committee of Secretaries to Government of India.• Coast Guard designated as Central Coordination Authority.
OBJECTIVES:• Intended to delineate entire national preparedness & response system including both public & private resources for responding to all spill emergency.• Provides the basic framework & guidelines for a national response to a significant spill at sea.
NOS – DCP• Earlier Ministry of Defence was nodal agency for coordination.• Now Ministry of Home Affairs is the entity / nodal agency.• NOS – DCP promulgated to all agencies after consent of Ministry of Shipping Road Transport & Highways, Ministry of Petroleum & Natural Gas, Ministry of Earth Sciences, Ministry of Environment & Forests during 1996.
NOS – DCP CONTAINS:• Duties of Indian Coast Guard.• Scope & objective of plan.• Organizational structure.• Reporting & alerting procedures.• Assessment.• Disposal of oil.• Capabilities of resource agencies.
• Tier 1 – Arrangement by the Individual ports & oil handling facilities to deal effectively with small operational spill up to 700 tons.
• Tier 2 – The pooling of government or privately owned resources at a local level to respond incident which may exceed, either in size, complexity or due to its remote location.
• Tier 3 – Arrangements for a combined national or international response to a major oil spill that cannot be dealt with effectively under the tier 2 arrangements. Cooperative arrangements have been established between groups of oil companies for responding to such events.
TIRED RESPONSE CONCEPT – IMO CLASSIFICATION
NOS – DCP RESPONSIBILITIES:• Port authorities responsible action within port limits.• Oil industries in & around their area of operation.• Coastal State PCB for inter tidal zones, beaches & up to depth beyond which CG ships & craft cannot operate.• Coast Guard responsibilities lies beyond port limits.• Director General, Indian Coast Guard has overall responsibility for appropriate response to oil spill incidents.
NOS – DCP PROGRESS:• Industries & ports advised to develop & establish Tier – 1 capability of oil spill response by end 2008.• State PCB have been requested by NOSDCP to prepare the contingency plans for their coastal waters for mitigating the effect of oil pollution.• ICG maintains stockpile of PR equipment capable of combating oil spills up to Tier – 2 level.• MoU’s between resource agencies being encouraged for pooling of resources and manpower.• All Indian flag ships, oil handling facilities in ports, coastal oil refineries & offshore oil platforms operating in the maritime zones of India will have onboard the coast guard approved oil pollution emergency plan by end 2006.• ICG plans to develop its capabilities up to Tier – 3 level of oil spill response.
INTERNATIONAL COOPERATION:• India surrounded by seven maritime neighbouring countries.• None have any specific oil spill response capability.• Only India has Tier – 2 capability.• India progressing for multilateral agreement for South Asia region.• Regional oil spill contingency plan under the auspices of SACEP for coordinating quick response in the region.
NOS – DCP RESEARCH & DEVELOPMENT:• Formulated guidelines for use of oil disperant.• Formulated guidelines for inspection of equipment, contingency plan etc. for ports & resource agencies.• Associated with MoES for –
a) Development of oil spill modeling systemb) Development of environmental risk assessment guidelines for oil spill management in costal watersc) Mapping of eco-sensitive areasd) Development of data base on environmental parameters
TECHNICAL CO - OPERATION:• ICG conducts frequent programme for industry & port personnel.• Conducts frequent mock drill & pollution response exercises to evolve common working / response philosophy & to maintain the response preparedness.• Conducted IMO level – 1 (equivalent) training programme for Sri lanka & short courses for other neighbouring countries.• Conducts frequent exercises with neighbouring countries to fulfill the requirement of regional oil spill emergency plan.• Effort in hand to undertake IMO level 2 & 3 training on oil spill response with assistance from IMO.
TECHNICAL CO – OPERATION PROPOSED TRAINING UNDER SACEP:In order to enhance the regional capabilities in compliance with OPRC conventions following proposed – • Conduct of OPRC level – 2 & 3 course for supervisors & on scene commanders in the region• Regular regional seminar & workshop on
a) Implementation & enforcement of marpol 73 / 78b) Ship recyclingc) Ratification & implementation of the international convention on OPRC – HNS protocol
• Cross deputation of personnel for training / seminars / workshops among South Asian countries to enhance coordination & cooperation• Conduct of pollution response exercises with participating members in the South Asian region
ACHIEVEMENTS:
With accreditation to OPRC & promulgation of NOS – DCP, ICG responded to

MSC Chitra Oil Spill off Mumbai
MSC CHITRA OIL SPILL OFF MUMBAI• August 7, 2010 (09.48 hrs) – MSC Chitra collided with MV Khalijia – III about 10 Km of Mumbai coast.
• 2662 tonnes fuel oil 283 tonnes diesel 88040 litres of lubricant
• 1200 containers (sodium hydroxide & pesticides)
• Vessel tilted 45 degree soon after collision
• Spillage of about 400 tonnes.
• Coast Guard began combating operation on 8th August using oil spill response vessels & aircrafts for spraying dispersants
• Oil spillage on beaches of Mumbai & neighbouring Raigad areas
• Oil also sighted at Sewri & Colaba areas
• 300 containers tumbled into water so far
• Pesticides bottles were found in Colaba & Raigad areas
• Mumbai & JNPT ports closed for the heavier traffic
• MPT hired SMIT salvage, Netherland company to salvage the containers & resurface the vessel.
MSC Chitra
RESPONSE OPERATION• First of its kind to be mounted in Indian waters.• The Indian Coast Guard deployed 5 ships, one helicopter and one small aircraft to monitor the oil spill & guide the response efforts.• The Dutch company, SMIT Salvage carried out salvage operations.• The assessment of areas affected by the oil spill was carried out by Maharashtra Pollution Control Board.
• The response was an overall success, further improvements can be made by addressing the aforementioned issues such as logistics, communications and the need for expediting customs clearance in the event of an emergency, by the Indian authorities.
• In India, appropriate guidelines and policies such as the National Oil Spill Contingency Plan are in place which provides the guidelines for response for the incidents like this.
• Though the review and implementation of the lessons learned, further improvements can be made to the existing plans to address any further events more efficiently.
