The Ministry of Energy and Energy Industries assessed the National Oil Spill Contingency Plan of Trinidad and Tobago (NOSCP, 2013) for its effectiveness as a preparedness and response mechanism. Using the Readiness Evaluation Tool for Oil Spills (RETOS™), the NOSCP attained a score of 42% in the Level A Assessment. Gaps were identified in areas including National Legislation, Risk Management, Logistics, Training and Exercises, and Operational Response. Further, lessons learned from past spills were examined to highlight deficiencies in oil spill response (OSR) planning and readiness. Proposed updates to the NOSCP include: designation of appropriate Lead Agency depending on the nature of the spill scenario, mandating Oil Spill Risk Assessments, and the use of SIMA as a decision-making tool for oil spill response; development of comprehensive guidelines for Dispersant Use, Oiled Wildlife Response and Oil Spill Waste Management. The NOSCP is being re-designed to facilitate a national response management system that meets best management practice for oil spill contingency planning. This will enable the efficient and effective deployment of the appropriate resources (equipment, expertise and oversight) to mitigate impacts to human health and the environment, and minimize production down time and socio-economic costs.
