James, we have finally gotten a response from NHPC on the gas curtailment issue. The natural gas 

supplier was not very helpful is specifying a maximum amount of curtailment that could 

occur. However, NHPC believes that 700 hours per year curtailment would be more than 

adequate. This represents 8% fuel oil burning, significantly below the 15% we had in the application. So 

hopefully this is acceptable to EPA. Attached are updated tables which incorporate the 700 hours 

limitation. Please let me know if you require any further information.

Phil/Dave,

I know you are mostly likely still working on supplemental application materials based on our discussion 

of the form the GHG BACT limit will take. However, I was hoping you may already have some project 

emission calculations for all pollutants based on the 48hr fuel oil use scenario, which differs from the 

15% worst case scenario in the original application. If this is available already, could you please send me 

a copy when you have a moment? We are trying to get ahead here and have a draft preliminary 

determination as complete as possible in-order to expedite as much as possible the writing of the permit 

when your GHG BACT information is in hand. Thank you.

Regards,

James Purvis

James, I apologize for the delay in getting back to you. It would really be easier for us if we could discuss 

the BACT limitation on Thursday or Friday, as Dave Buff, the senior engineer working on this project with 

me is in a conference through Wednesday. Is there a good time for you on Thursday or Friday?
