The following items were discussed: 1. Introductions for all the team members and their roles were discussed. The following .was established: a. John Masson will be the primary contact and project manager for UNC. b. Mike Meagher will be the prime contact for .technical information and site visits required at the landfill. The team can correspond directly with Mike, but should copy Gayle and Bob Sallach on all requests for information. 2. The initial feasibility study includes taking samples at the landfill for gas quality and presence of contaminants. These samples will be taken in the next few weeks and lab analysis will follow. 3. RSG will be using landfill records to develop the gas quantity estimates. Standard EPA modeling will be used. a. Olver, Inc. has prepared some very preliminary numbers for estimated gas available. These preliminary estimates to be sent to RSG for review. b. Orange County to provide landfill records for RSG use. 4. The leachate is currently pumped and hauled form the site. Orange County is in the process of installing a system that has a direct connection to OWASA sewer. The equipment will be located on the south side. a. It would be desirable to bring all gas to a central location for clean-up. ~-~fi[it+ed ~Et~in 1414 Raleigh Road, Suite 305 Ghapel Hill, North Carolina (919) 419-9802 (Fax 419-9803) Meeting (dotes UNC -Alternative Energy Analysis landfill Gas Investigation Project University of North Carolina- Chapel Hill Owner Project Kick-off Meeting Type of Meeting 08029-00 Project No. 01 /17/2008 Meeting Date Page 2 of 2 ias Page Typist b. The new landfll "clean-up" system required for this project should be able to use this same discharge connection. Based on that, it would make sense to have this equipment on the south side. 5. Orange County wotald prefer that a shielded, enclosed flare be used and included in the analysis. Although this is a more expensive option, it provides a shielded flame that is not visible from remote locations. 6. The three options under consideration were reviewed. The three options are: a. Power only at Duke Energy Substation site on Homestead b. CHP (Combined Heat and Power) at Carolina North site c. Gas use (TBD) at existing Cogen site 7. The pipe routing form the landfill to Carolina North or the Cogen Plant was discussed. AEI noted that the railroad corridor is the most direct route for any of the options, but dialog with the railroad needs to take place to confirm the possibility and restrictions. UNC to investigate the potential of these discussions. 8. Orange County to provide current electrical rates and available capacity for service at the landfill. Orange County noted they had 3-phase service available at the planned leachate treatment pond. 9. The ownership and operation of the flare system was discussed. Although it is planned that the flare would only be used in events where all the gas can not be consumed, it seemed to make most sense for Orange County to have control of flare operation. 10. It was noted that cost for capping/closure of the South landfill would need to be incurred. This closure is currently planned for 2012. 11. The next meeting is scheduled for February 4th at 1:30 pm.

The following items were discussed: 1. The progress to date includes: a. Obtaining and reviewing the landfill records. b. Obtaining gas samples and sending to lab for testing. Results are expected in about 2 weeks. The initial readings indicated methane quantities ranging from 58% to 62%, which is good. See attached map for graphics and preliminary sampling data. c. Gas generation estimates have been started. Using L° = 100 and a collection efficiency of 85% for the North site and 75% for the South site, there is approximately 420 CFM of gas available at the peak in 2011 to 2012. This quantity will remain above 310 CFM for at least 10 years and should be able to produce between 0.75 and 1.0 Megawatt of power. d. Preliminary pipe sizing and equipment selection/pricing for Prime Movers has begun. e. Current electrical and gas demands at Carolina North (existing Facilities Services buildings) have been quantified and season usage curves have been developed. 2. Based on the preliminary data, it is estimated an 8" to 12" gas main will be required from the landfill site to the point of use at UNC. Routing paths and costs are being investigated. 3. Based on the preliminary gas estimates and current loads at Carolina North, it appears that a power generation capacity of 0.75 Megawatts should be considered. There is sufficient load to utilize approximately 80% of the potential power generation (750 Kw) available in Year 1 (likely 2010), with this growing to 100% by Year 5 (2015) as new buildings develop at Carolina North.

UNC will set up a meeting with the Cogen personnel to discuss use of the landfill gas at the Cogen site. Although this has the longest pipe run, it is a location where the LFG can be fully utilized immediately to offset coal consumption in the boilers. 5'. RSG will investigate other sources of income for the project. The following were discussed: a. Grants- REPI program (Renewable Energy production Incentive). This is a federal program that may possibly offer some grant money for the project. b. Golden Leaf Foundation -not likely as this is typically tied to job creation. c. It was decided that a special appropriation from the State Legislature is not likely for this project, based on UNC's experience with the 01NASA reclaimed water system. 6. The final Agreement was discussed in general. It was decided that the Agreement would need to define the following items: a. Ownership and operation of equipment at landfill site (Flare, clean-up equipment, compressors, etc.) b. Access and easements at landfill site c. Who is responsible for purchase and installation of the gas collection and flare system at the landfill? d. Permitting responsibilities e. Timeline for implementation f. Who retains carbon credits and how are they valued? 7. The next meeting is scheduled for February 21st at 10:30 am.
