CCS RA/RM Frameworks Worldwide
Many frameworks have been created o More than a dozen regulatory and non-regulatory organizations have
sourced documents and online resources
o The majority of regulatory documents have come out of international/regional (EU) entities
Elaboration varies o May simply mention a requirement, or may spell out specific inclusions
or approach
o Focus is often chain specific - Capture, Transport, Injection, Storage
Most comprehensive documents o Regulatory - UN Framework Convention on Climate Change – Clean
Development Mechanism, Modalities and Procedures for CCS (2011)
o Advisory - World Resources Institute (2008), DNV GL, US NETL (multiple)
6
Elaborated Frameworks
• Primary focus on injection and storage
• Many documents address storage site selection and characterization o 4-step RA (Hazard Characterization, Exposure Assessment, Effects
Assessment, Risk Characterization)
• Few frameworks link with an assessment of emissions, waste, or water use
• Uncertainty, stakeholder communication and consultation, and transparency are discussed sparsely in the regulatory context and frequently in non-regulatory documents
• Some non-government guidance includes a discussion on methodologies for risk ranking; government documents do not
7
Attempts at Integration
• Bowden and Rigg (2004)
o Features Events Processes (FEP); use of expert panel; community interface
• FutureGen (2007)
o 1000s of pages with web access
• Hnottavange-Telleen et al. (2011)
o Stressed that risks perceived by all stakeholders are equally important (public and expert)
• Koorneef et al. (2011, 2012)
o RA within broader Environmental Impact Assessment; transparent process
8
Attempts at Integration (con’t)
• Shell Quest (2012)
o Documentation and regulatory decision
• Bowden et al. (2013a, 2013b)
o Socially acceptable risk concept
• Gerstenberger et al. (2013)
o Methods and tools available for integrated risk assessment, including expert elicitation, in order to respond to uncertainties and limited data; communication
• Choptiany and Pelot (2014)
o Multicriteria Decision Analysis; interactive engagement

Structured Expert Elicitation
• To improve understanding of relative risk and quantification of collective uncertainty judgments
(Aspinall, 2010; Cooke & Goossens, 2008)
• International expert panel convened regarding risks and attendant uncertainties
– Injection and storage
– Risk management of high impact low probability events
• Full analysis yet to be completed

What should be the storage project monitoring period (years)?
17
• Experts thought storage monitoring period should extend between a decade through a millennium
• Best expert judgement is approximately a century
