Science Assessment Activities 2004-05

1. Science Assessment Activities 2004-05 • The Science Assessment and Integration Branch provides an integral link between the science and policy communities • We provide relevant and timely science to policymakers in order to base Canadian regulatory strategies on sound science • Key air quality functions include: PM, Ground-level ozone and acid deposition • Some of the programs that we provide science advice and input to include: • Canada-U.S. Air Quality Committees • UNECE Working Group on Effects • CCME working groups • Acid Rain Task Group • Canada-Wide Standards Working Groups

2. Smog/Acid Rain Policy Context • CCME houses the Canada-Wide Standards process, under which sits the JAICC and the Acid Rain Task Group • Both of these committees will be replaced at the end of the FY with the AMC • The AMC will take on CWS responsibilities and will have sub-committees as needed • Science input (ambient levels, process, models, emissions, S-R work) will still be incorporated into the CWS process • Next CWS review is still scheduled for 2010, with a science assessment required for this review • Looking to renew Acid Rain Business Case and potentially revising the Strategy for Post-2000

3. Acid Deposition: 2004 CARSA • Main deliverable for the acid rain program for 04-05 • Background: • In 2000, agreement to produce the 2004 science assessment. • In 2001/02 policy-makers were engaged in the development of science questions. • In 2003/04, production of chapters.

4. Acid Deposition: 2004 CARSA Next Steps: • Nov. 20, 2004 - Summary of key results to be presented to Acid Rain Task Group of CCME • Dec., 2004 – Publication of Assessment • Jan-Feb, 2005 – Assessment sent to ARTG and stakeholders in preparation for a CCME/ARTG-sponsored Science/Policy Workshop in Feb. • Feb. 23-24, 2005 – CCME/ARTG-sponsored workshop on the policy implications of the 2004 Canadian Acid Deposition Science Assessment.

5. Particulate Matter Assessment Activities • 2004 Transboundary PM Science Assessment in support of future Canada-U.S. negotiations on PM (PM Annex 2006) • Assessment was developed by both Canadian and U.S. scientists, coordinated by SAIB • Bi-national peer review completed and technical edit completed October 15th, 2004 • Translation and publication to be completed by the December Air Quality Committee meeting in Ottawa

6. Other PM Assessment Activities • Ammonia report for the National Agri-Environmental Standards to be completed by the end of 04-05 • Support for the BAQS – • Emissions trading feasibility study • Ontario Region Pilot project • Possible data analysis support

7. Ozone Assessment Activities • Last assessment was in 1997 • recent focus has been on PM, Acid Dep. • Science update completed in 2003 for CWS process • Proposing a SMOG Assessment (PM and Ozone) Other • Coordinated science input to AQA biennial Progress report

8. Future Assessment Activities • 2005 Smog stakeholder workshop in support of CWS activities and to complete JIA#7 sunsetting of JAICC (Tentative date: March 7-9, 2005) • Support for new Air Management Committee • Launch of 2007-08 Smog Science Assessment to be completed prior to the 2010 CWS review • Coordination of Canadian input to the Acidification Chapter of the Arctic Monitoring and Assessment Program • Science support as required for Canada-U.S. PM Annex negotiations
