2 East Bend Test Site Duke Energy East Bend Plant outside of Rabbit Hash, Kentucky 20 miles southwest of Cincinnati East Bend Test Site Duke Energy East Bend facility 650 MW coal-burning power plant SOx and NOx control systems 1,800 acres on the floodplain along a bend in the Ohio River 2

3 East Bend Test Site The plant is an industrial setting, with various generating buildings, coal staging areas, and other facilities. The site is located on an active plant which is providing property access for the field work and other support that should aid in completing the project. Phase II Public Outreach General Activities Updated website to include Phase I report and Phase II activities Developed a series of generic, detailed fact sheets concerning geologic and terrestrial field tests Continued to collaborate with other partnerships in planning research into public perceptions Continued to participate in Outreach Working Group activities 3

4 East Bend Test Site- Public Outreach Solidified working team for each geologic pilot consisting of staff from host company and MRCSP Planned outreach according to planned seismic survey and injection testing Developed a series of site-specific fact sheets, video clips, briefing materials for each geologic field test Ensured that state and local officials and nearby residents received notice about the planned pilot and seismic survey (if applicable) in person, via letter or telephone call More than 1,300 information packets mailed within 5-miles of the plant East Bend Test Site- Public Outreach Coordinated with Duke Energy in planning interactions with employees, officials and nearby residents prior to beginning seismic survey, scheduled for October Developed a series of information materials tailored to the various stakeholders (neighbor letter, fact sheet, briefings) At request of local officials, conducted a briefing for local officials and an Open House for nearby residents, including a series of exhibits, seismic video and take-home materials, as well as opportunities for one-onone discussions with technical staff Now developing follow-on materials to address questions raised in the meetings and planning for subsequent project phases 4

5 Phase II: Geologic Field Test Plans Preliminary Geologic Assessment Site specific assessment of target storage reservoirs and geologic setting. Performed by state Geologic Surveys. Site Characterization/Field Work Seismic surveys, test-well drilling, reservoir tests, brine sampling, other field work at the demo sites. Site characterization data will be used to design injection well and monitoring programs. CO 2 Injection Tests and Monitoring CO 2 injection testing and monitoring/verification. Objectives vary by location due to different storage targets, CO 2 sources, and system design. Monitoring will be completed to evaluate injection system, CO 2 migration, and health & safety. Arch Site Geologic Setting Preliminary geological assessment completed by Indiana and Kentucky Geological Surveys 5

12 Preliminary Conceptual Injection System Injection system located on site. Additional Monitoring well under consideration MMV To be Finalized Monitoring options were reviewed and a subset of options was selected based on the proposed injection system specifications and geologic setting. Complete monitoring plan and schedule will be determined after site characterization efforts are finished. Since the injection interval is fairly thick, the monitoring approach may involve tracking the upward migration (if any) of the injected CO 2 to assess.
