Subject: RE: SPI Anderson PSD Modification Additional InformationHi Eric, I do not have definitive response about the draft permit. In tandem with the draft permit, as you

probably know, I have to draft the Ambient Air Quality Impacts Report which requires more technical

detail. Thanks for your help and have a good weekend.

Omer:

Thanks for the reminder, was out of the office most of last week, and have been catching up on things all

of this week. I sent some ideas to Dave Brown, but haven’t been able to connect with him yet to finalizeour responses. I’ll try to get the information to you sometime next week.

Realizing that you haven’t received a response to this information request, do you have any estimate ofhow soon a draft permit will be ready for review?

Thanks, end have a good weekend.

Subject: SPI Anderson PSD Modification Additional Information

Hi Eric, I would like some clarification on the following issues regarding emissions, operations and general

criteria. I think these will be helpful in organizing the permit and technical support document. Thesequestions are more or less in an order of priority in terms of drafting the proposed permit.

Emissions

1 Do the block emissions daily averages in the application also include periods that contain instances of
and shutdown events (the application states an average number of 2 shutdowns per year) that are to

occur in a year and their duration (the application describes the cold start of 24 hours)? What are the elevated maximum level of emissions for each criteria pollutant per event in this case? If the block

averages from Emissions 1. above includes periods that may contain startup and shutdown events, then this point may be of less significance.

3. What is the actual steam limit to be imposed on the new boiler?

General Criteria1. What types of fuel are currently permitted at the facility and what additional fuels may be burned in the future?

2. Are there any restrictions on the amount of natural gas or other fuel to be burned at the facility? This will influence some fuel handling conditions and perhaps source test requirements.

Thanks for your help.
