Other Items for Steering Committee Awareness P&RA COP Session Description: This session is to introduce the Performance and Risk Assessment (P&RA) Community of Practice (CoP), which has the goal of fostering the exchange of information regarding preparation of P&RAs across agencies and practitioners; enhancing consistency in the preparation of P&RAs; and developing appropriate peer guidance and/or recommendations for P&RAs such that they are based on sound science and are defensible. Upcoming P&RACOP meetings will discuss various P&RA issues for practitioners, potential solutions, and case studies. In this panel, the P&RACOP Steering Committee members will introduce the P&RACOP, discuss upcoming meeting plans, and provide the audience with the opportunity to provide their input on potential topics for future P&RACOP meetings for technical areas of interest. o Which panelists from the SC? o Notes from last meeting: David or other Co-Chairs will provide an overview of the P&RACOP P&RACOP Steering Committee members will discuss key topics regarding P&RAs that we as a community will need to build consensus on; the experience the Steering Committee members bring; and what they envision that the P&RACOP could help address moving forward Ask stakeholders on what they are interested in seeing from the PRACOP May ask private sector people to see what topics may be of interest to them 4

CRESP There was a suggestion that we consider creating a database of EM sites R&D activities (and potentially other groups as well) such that these R&D reports when available could be broadly shared (assuming only publicly available info would be on this database). Questions for the group: o Do we have funding for CRESP support in Fy25 for this? o Is it worthwhile and would be beneficial to PRACOP members? 5
