- WELCOME AND ROLL CALL
Those present during the meeting included Rick Artz, Gary Foley, Harold Garabedian, Paul Lioy, Don McKay, Kathy Tonnessen along with John McDonald, Kelly Montgomery and Christina Cheng of the Commission staff.
The U.S. Co-Chair, Gary Foley chaired the meeting.
- APPROVAL OF AGENDA
Due to time constraints, the order of the agenda was rearranged to accommodate guest speakers. Item 6.0 Development of 2003/05 Great Lakes Priorities was to be discussed prior to the guest presentation, followed by Item 4.0 Special Transboundary Report and subsequent items as outlined in the agenda. The revised agenda was approved by all participating members.
- REVIEW OF RECORD
- IAQAB Conference Call - March 4, 2003
Board members approved the minutes to the March Conference Call. The Secretary asked that any subsequent minor changes are to be forwarded to his attention in the next few weeks to allow for inclusion in the final record.
- SPECIAL REPORT II
There was a general consensus among participating Board members that, in addition to the material prepared thus far for the Special Report, further research, analysis and drafting by Board members would be required. It was acknowledged that the draft is a work in progress, noting further material will be gathered and developed to complete the draft material before linking the sections together.
Further explicit linkages to the previous Special Report as well as other Board reports remain to be established. Issues considered in the first Special Report should be updated, noting those that have been borne out and those that continue to emerge.
The Board agreed to allocate one full day at the next IAQAB meeting for the Special Report in order to develop conclusions and recommendations, and to finalize the report, which must be completed no later than the Fall 2003 Semi-Annual meeting.
PRESENTATION: Emission Caps and Trading: Expanding a Proven Concept for Multipollutant Reductions - Rona Birnbaum, Clean Air Markets Division, USEPA
An overview of the proposed Clear Skies initiative was presented by Ms. Birnbaum of the US Environmental Protection Agency. (See attachment) The Clear Skies program is designed to apply a multipollutant strategy for sulphur dioxide, nitrogen oxides, and mercury to electrical utilities, particularly those fired by coal, that are large emitters of these pollutants. An introductory discussion on the development of the Clear Skies program emphasized the benefits of adopting the initiative, including early emission reductions, flexibility and cost effectiveness.
Clear Skies includes elements of the Clean Air Act - specifically the National Ambient Air Quality Standards (NAAQS), which remain the ultimate test of attainment, and the associated requirements for State Implementation Plans and other regulatory initiatives such as those pertaining to Regional Haze reductions.
Projected emissions are based on the application of the cap and trade tools of the program. Sulphur dioxide emissions have been decreasing notably over the past several years and Clear Skies will result in earlier reductions, with a leveling off under the cap in the longer term. Nitrogen oxides emissions are also decreasing; however reductions to date are not as significant nor as immediate as seen with SO2. Mercury reductions are projected to be significant, ranging from 25-50% reduction in some areas of the US.
- DETROIT/WINDSOR - SARNIA/PORT HURON + SAULT STE. MARIES ACTIVITY
An overview of the available draft material was provided by John McDonald. It was agreed that Harold Garabedian would make a presentation to the Commission on the work to date and further developments on the report would be dependent on the response of the Commission.
- DEVELOPMENT OF 2003/05 GREAT LAKES PRIORITIES
Board members discussed the development of priorities and re-iterated their understanding that the process would include existing priorities as well as new interests. The Board would propose a continued focus on modeling estimated deposition of mercury in Canada and the United States based on projected reductions in emissions. The Board also agreed to propose continued tracking of the progress of the METAALICUS (Mercury Experiment to Assess Atmospheric Loading in Canada and the United States) project to deter the fate of mercury deposited in a small lake basin in the Experimental Lakes Area of Northwestern Ontario.
The Board would also propose to continue tracking the progress of the European Intercomparison Mercury Modeling project, which includes the HYSPLIT (Hybrid Simple Particle Lagrangian Integrated Trajectory) model and the RELMAP (Regional Lagrangian Model of Air Pollution) model among several others.
Board members expressed interest in supporting the SAB Urbanization/Land Use priority, as well as the WQB Climate Change issues, should both be selected for continuation. It was suggested that a Board member be designated to participate in further development of the Great Lakes Climate Change review with the Water Quality Board, including participation in their workshop on this issue, to be held in Detroit on May 28 and 29/03.
- OUTLINE OF IAQAB CHAPTER - 2001/03 GREAT LAKES PRIORITY REPORT
The Secretary reviewed the draft outline of the IAQAB chapter of the IJC 2001/03 Great Lakes Priority Report. The date for submission of the completed and final chapter is May 9, 2003, at which time the layout and preparation of the entire document would commence. Mark Cohen will be assisting the Board by drafting the portions of the IAQAB work involved with the HYSPLIT monitoring of mercury deposition in the Great Lakes basin. Rick Artz provided an update on the work performed by Dr. Cohen, who continues to improve and verify his model and should be able to provide his material within the time frame.
The IAQAB commented on the Chicago Urban Plume and its impact on IADN (Integrated Atmospheric Deposition Network) , and estimated mercury flux values in Lake Michigan (see G. Keeler paper, Environmental Science and Technology, 2002), which suggests that, while much of the deposition is reactive gaseous mercury (RGM), elemental mercury is the dominant species of the re-volatized material).
A copy of the chapter material should be made available for review by the Board prior to its submission to the IJC-GLRO editing and layout process.
- UPDATE ON MERCURY WORKSHOP, BIENNIAL FORUM
The material the IAQAB would present at the Biennial forum was discussed, which would largely be a presentation by Mark Cohen or Rick Artz on the HYSPLIT mercury modeling.
- REVIEW OF AGENDA FOR IAQAB PRESENTATION TO COMMISSION
In its presentation to the Commission, the Board agreed to limit the discussion on the Special Report II to an overview of the report; the primary focus would be on the Detroit-Windsor, Port Huron-Sarnia and Sault Ste. Maries presentation.
- IAQAB SUPPORT FOR EPA/ENVIRONMENT CANADA LRTAP-PTS WORKSHOP
John McDonald provided an overview of the Long Range Transport of Persistent Toxic Substances workshop to all Board members. Dr. Hans Martin has been retained to draft a Challenge Report that will be forwarded to the Board. The workshop coordinators will likely ask for financial assistance from the IJC.
The Board noted that the workshop did not appear to deal with the outputs or improvements that might be associated with current and proposed control programs. It was also noted that the timing was in conflict with the A&WMA (Air and Waste Management Association) annual conference in San Diego. Also, there did not seem to be adequate time to secure the high profile speakers necessary for a significant event; the anticipation that individuals would attend both the IAGLR (International Association of Great Lakes Researchers) meeting and this event, and stay for a week in Chicago seemed unlikely. Board members suggested incorporating the workshop into the IAGLR conference. Some significant re-tooling appeared to be necessary. John McDonald will relay the concerns and suggestions of the Board to the planning committee and will inform the Board of the response.
- OTHER BUSINESS
- Water Quality Board, Climate Change Workshop - May 28-29, 2003
Board members would prefer to pursue the effects of Climate Change on air quality at a later date. The Board may wish to designate an external representative on behalf of the Board to attend the workshop. Deb Mangas of USEPA or Julian Wang of NOAA were suggested as possible participants; the Secretary was asked to determine if either had been invited.
John McDonald will secure the most recent version of the WQB Climate Change White Paper prepared for the workshop and forward it to Board members for their consideration.
- SAB Liaison - Dr. Judith Perlinger
The Board recognized Dr. Perlinger as the liaison from the SAB.
- IJC Health Symposium
Paul Lioy cannot attend the symposium. John McDonald will contact Michael Brauer to seek his participation. Paul Lioy offered to designate a representative on Air Toxics should the agenda include a segment on this topic. The Secretary will discuss the possible requirements with Dr. Brauer.
- NEXT IAQAB MEETING
The proposed location of the meeting is Winnipeg, Manitoba, with a field trip to the METAALICUS project in the Experimental Lakes Area of Northwestern Ontario. July 28-31, 2003 were chosen as the dates. As mentioned earlier, one day of the meeting would be dedicated to the completion of the Special Report II. As more specific details come available, John McDonald will forward them to the Board.
- NEXT IAQAB CONFERENCE CALL
The next IAQAB conference call was confirmed for Tuesday, May 6, 2003, 1:30-3:00 p.m. EST.
The meeting was adjourned at approximately 5:00 p.m. EST.
