Comments & Observations:Particulate Matter Case Study EPA-NSF TransAtlantic Uncertainty Colloquium October 10, 2006 Washington D.C. Justin Babendreier Office of Research and Development, NERL/ERD
Overview • Anticipation & Adaptation • Well developed case study comparing outcomes of EU and US regulatory efforts/processes in regulating PM over last 30 years. Excellent e.g. • Some Upfront Conclusions • States the Obvious: adaptive learning = good • An underlying theme not necessarily called out but apparent is the issue of time-scale in A&A • Could better develop quan. & qual. information regarding how UA/SA were incorporated (or not) into policy formulations at different points in t.

Key Issues of Good Policy-Science Interface (similar factors of influence for success) • High Quality Knowledge Assessments • Notable: when stakes are high (vicious) attacks on science/data are unavoidable. • Where lacking = lack of success • Conflict is inevitable. KA has to be sound/honest. • Incentives to Surface Information • Example of how Acid Rain Program influenced process • Notes how post-decision incentives sometimes lacking • Need mechanism to keep process honest/on-schedule. • Opportunity for stakeholder lawsuits appear beneficial • Can be abused by those simply desiring to delay action/decision
Similarities between US & EU • “Remarkable” based on same science/data • Note: negative for EU that much was US data • Note: causal inference is associative: actual mechanisms of toxicity/mechanisms of exposure, not well understood…..many confounding issues. • Both have used adaptation (decadal scale) to successfully affect health policies • Both have achieved high levels of transparency
Differences between US & EU • US has led in adopting new standards • US standard (PM2.5) more stringent • EU standard (annual PM10) more stringent; US has since dropped their standard (i.e., adapting). • US in this case more precautious….i.e., PP (??) • EU hasn’t had a direct mechanism to allow stakeholder lawsuits to enforce review/schedule (prior to 2001) • One big reason for differences appears to be that CAA does not allow EPA to consider cost of adopting air quality standards • Some EU politics external to decisions on AQ
Other thoughts • Mapping of Q/Q UA to policy decision process key • Problem formulation/framing • Stakeholders • Selection of Indicators • Assessment of knowledge • Mapping/assessing relative uncertainty • Reporting UA …Parameter uncertainty is a key but not enough….. • Time Scale for Adaptive Learning/Policy Adjustment • Successful tadaptation ? CCA =5 years; 9 years, 10+ • tadaptation = f (stakescost, stakesbenefit, political cycle, science & technology cycle, peer-review cycle, etc, etc.)?
Final thoughts • Data is good….it is the basis of A&A • Isn’t that what we are all really just saying here…. • Whatever happened to post-auditing of model-uses? • Post-decision monitoring….needs to be integral to decision-making process. • On long time scales (10-20+yrs), already is integral….. • Economy, Economy, Economy…. • It drives ultimately everything we do… • Strategically….we might want to concentrate, understand better ways to create (equitable) incentives for data collection as part of the adaptive (policy-making) process.
