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 curtailmen t 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,
