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
