# EPRI 2011 Accomplishments, Ongoing R&D and Preliminary Plans **for 2012 Meeting Agenda:** 

 Introductions  Meeting purpose/goals  EPA questions on EPRIcomments or technical reports  Status of NODA  Review of ongoing research and potential 2012 R&D 

# Meeting Objective : Opportunity for EPA to ask questions on EPRI2011 research and on our technical comments on the proposed Rule. Most importantly, EPRI is formulating its 2012 R&D plan and input from E PA on relevance & importance is considered extremely important by our members. 

# EPA questions on EPRI **technical com**  **ments or technical reports:** A list of EPRIsubmitted reports is on following page. The following reports were not submitted but are near c ompletion. Copies will be sent when they are available: **Full -**  **time/Seasonal Closed**
