COMBATING THE SPREAD OF SPILLED OIL

OUR COMMON ENEMY IS THE SPREAD OF SPILLED OIL AND ITS IMPACT ON OUR SHARED

VALUES

Spill Impact Mitigation Assessment

(SIMA)

New IPIECA-IOGPGood Practice Guidance

SIMA is also a methodology for NEBA that is:

• Transparent

• Holistic

• Qualitative

• Even-handed

• Flexible

Net Environmental Benefit Analysis (NEBA)

transitioning toSpill Impact Mitigation Assessment (SIMA)

Better reflects objectives, decision framework and

shared environmental values

i.e. ecological, socio-economic and cultural

Removes perceptions of spin associated with the

word ‘benefit’

Principles unchanged

4 Stages of SIMA

• Know your oil

• Model fate and

trajectory

• Sensitivity data/map

• Identify potential

response options:

• Effectiveness

• Feasibility

• Regulations

Benefits Drawbacks

• Removes surface oil that could harm wildlife and

keeps oil from spreading to shoreline; enhances

natural biodegradation of oil and reduces vapors

on water surface

• Dispersed oil has the potential to initially affect

local water column-dwelling wildlife and

vegetation

• Removes oil with minimal environmental impact • Mechanical recovery can be inefficient, resource-

intensive, and restricted by water conditions, with

typically no more than 10-20 percent oil recovery

• Removes large amounts of oil rapidly via

controlled burning

• Burning presents a potential safety risk and

localized reduction of air quality; burn residue can

be difficult to recover

• Selectively restores environmental and social

value to specific locations using a variety of tools

• Aggressive or inappropriate removal methods

may impact ecosystems and individual organisms

• Takes advantage of natural processes for oil

removal, including biodegradation, and avoids

intrusive cleanup techniques that may further

damage the environment

• Natural removal can take more time to achieve

pre-spill use than other response techniques

Summary

• Qualitative process - relies heavily on expert /

professional judgement

• Understanding of the potential effects of a spill on

environment and other resources

• Help to evaluate various response options

• Address potential trade-offs for different response

strategies

• Overcome barriers during a response

• Government and industry working together cooperatively
