Lance,

Thank you very much for taking the time for the conference call with EPA on Dec 2. The information you provided on ash handling systems was very helpful, and we hope to continue the communications with you as EPA progresses through the information collection stages of the Steam Electric rulemaking. As we discussed during the conference call, EPA would appreciate your comments on Part C of the draft Steam Electric questionnaire, which can

be found at:

http://www.epa.gov/guide/steam/questionnaire.pdf

In particular, we would appreciate your input on whether EPA is asking the right questions for developing a model to estimate the cost of wet-to-dry ash handling system conversions (for both fly and bottom ash). EPA is also open to any other comments on how Part C or the rest of the questionnaire might be improved.

As we discussed during the conference call, EPA/ERG will be laying out an approach for the development of the ash handling system cost model, and EPA would appreciate Headwaters’ input at that time to help ensure that costs are estimated as accurately as possible. EPA would also welcome any other information that you could provide to help in this effort. As discussed, you may claim any information you provide as confidential. EPA will handle such information in accordance with the Agency’s strict confidential business information (CBI) handling procedures.

Please let me know if you have any questions for EPA, and feel free to contact Ron Jordan in the future. Ron’s contact information is provided

below.

Kevin,

Thank you very much for taking the time for last week’s conferen ce call with EPA. The information you provided on ash handling system s was extremely helpful, and we hope to continue the communications with you as EP A progresses through the information collection stages of the Steam Electric rulemaking. EPA is in terested in your offer fo r future meetings at power plants or at your testing facilities a nd plans to contact you s oon to discuss potential opportunities.

As we discussed during the conference call, EP A would appreciate your comments on Part C of the draft Steam Electric questi onnaire, which can be found at:

http://www.epa.gov/guide/st eam/questionnaire.pdf

In particular, we would appreciate your input on whether EPA is asking the right questions for developing a model to estimate the cost of wet-to -dry ash handling system conversions (for both fly and bottom ash). EPA is also open to any ot her comments on how Part C or the rest of the questionnaire might be improved.

Additionally, during th e conference call, you provided cost estimates for converting from wet to dry fly ash handling for a 600 MW generating unit. EPA would appreciate any additional cost curves or budget information th at you would feel comfortabl e providing that may help EPA predict the cost of converting to dry bottom/fl y ash handling at power plants. For example, during the conference call we discussed that econo mies of scale have a large effect on total system cost. If UCC has any "rules of thumb" to share with EPA (e.g., plants with 4 generating units generally need 2 silos, etc. ), we would greatly appreciate this information. We would also like to reiterate that you may claim any informa tion you provide as confidential. EPA will handle such information in accordance with the Agency’s strict confidential bus iness information (CBI) handling procedures.

Lastly, during the conference call, ERG ema iled you a link to EPA’s Final Detailed Study Report, which lists the power plants that EP A visited during the detailed study, and EPA asked that you identify at which of these plants you have been involved with wet-to-dry ash handling conversions. For reference, EPA’s site visit lis t can be found on page 2-5 of Final Detailed Study Report (link provided below).

http://www.epa.gov/guide/steam/finalreport.pdf

In addition to the facilities visited during th e detailed study, EPA also visited the following power plants recently in 2009:-Allen (NC) -Cape Fear (NC) -Catawba (SC) -H.B. Robinson (SC) -Monroe (MI) -Karn/Weadock (MI) -Kinder Morgan (MI) -Sanford (FL) -Polk (FL) -Chesterfield (VA)

Please let me know if you have any questions for EP A, and feel free to contact Ron Jordan in the future. Ron’s contact information is provided below.

Additionally, EPA would greatly ap preciate the compilation of cost and design information that you offered to provide to help in the developmen t of EPA’s ash handling cost model. Lastly, I would like to follow up on Ron Jordan's reque st for the DRYCON presentation that you presented at PowerGen as well as any other rele vant materials, papers, or ash handling system performance data that you or your European counterparts would be able to share.

We would also like to reiterate that you may claim any informa tion you provide as confidential.
