10:40 A.M.	BREAK

10:50 A.M.	Public Comments

11:30 A.M.	Charge Questions Part I: OPP’s Approach

Charge Question 1

OPP is seeking guidance on its approach to climate change to date and
suggestions on how to approach future work.  

Comment on the approach that OPP used to evaluate the models in light of
the expected likely effects and impacts of climate change to determine
whether climate change would influence the inputs and parameters.

Of the areas identified as likely to be affected or the effects are
uncertain, please offer suggestions as to the likely importance of these
factors on risk assessment.  Comment on potential approaches to address
the uncertainty. 

 

12:30 P.M.	LUNCH

1:15 P.M.	Charge Questions Part II: Temporal and Spatial Considerations

Charge Question 2 

OPP reviews chemicals and assesses risks as needed at least every 15
years.  Over a 15 year time period, pesticide use and crop residues from
monitoring data could change as a result of climate change.  

Based on current projections, will the pace of climate change
significantly increase the uncertainty in our exposure assessments?

If yes, which inputs are likely to change in such a manner that the
uncertainty in the exposure assessment would significantly increase? 
Comment on how OPP might explore this issue. 

2:05 P.M. 	Charge Question 3 

Over time, the environment will change due to climate change and these
changes will be manifested differently in different regions of the
country.  Irrespective of climate change, there already exists a wide
variety of climatic conditions across the country.  Because climatic
conditions vary greatly across the country, often data collected for
exposure assessments are from studies performed at multiple locations
chosen to be geographically representative of the entire country.

Please comment on the geographic changes anticipated due to climate
change relative to the existing climate diversity within the U.S.  Over
what time period might climate change significantly affect the range of
diversity in weather conditions in the U.S in such a way as to
significantly increase our uncertainty in pesticide exposure
assessments?

2: 55 P.M. BREAK

3:10 P.M.	Charge Question 4 

All exposure assessments rely in some degree on historical data –
weather, residues on food, cultural practices, pesticide use practices,
etc.  In many situations data that are directly used as inputs into an
exposure assessment can readily be updated with each successive
assessment.  For example, a dietary exposure assessment today would rely
on recent monitoring data, while an assessment in 5, 10 or 15 years from
now would rely on more up-to-date monitoring data than an assessment
conducted today.  In other situations, data are used to develop a
parameter in a model, such as the runoff curve discussed in section
III.B.1.e. of the background paper.  Please comment on the significance
of climate change on the reliability of embedded model parameters.  How
might OPP systematically approach an evaluation of the significance of
such model parameters?

4:10 P.M.	Charge Question 5 

Currently, OPP uses weather data from 1960-90 in its ecological
assessments, giving equal weight to every year.  OPP intends to acquire
more recent data.  Please comment on the effects of using these data in
light of climate change.  If this is viewed as an important factor, will
aggregating the data from 1960-2010 be appropriate in light of climate
change?  For example, would the use of data from the last 10 years be a
more appropriate indicator of future weather patterns or should OPP
consider adding a predictive component to weather data?  If the use of
predictive models is appropriate, provide any sources of ongoing
research or relevant models that might be explored. 

5:00 P.M.	Charge Questions Part III: Priority Setting

Charge Question 6 

Please consider a systematic approach for OPP to prioritize future work
on climate change.  Identify priority areas to help guide OPP in
determining inputs/models that would be most important to help assure
that our assessments do not underestimate exposure and risks (include
magnitude and uncertainty). 

5:45 P.M. ADJOURN

Please be advised that agenda times are approximate; when the discussion
for one topic is completed, discussions for the next topic will begin.
