 Subject: RE: Controls on existing pitch storage tanks 

 

Mr. Putney,

Below is the requested information from Intalco Aluminum 

Corporation regarding the existing pitch storage tank controls 

(refer to bold responses in red ). If you need any additional 

information, please don't hesitate to contact me.

Sincerely,

Kathryn Mitchell

Hello all,

The responses to the recent (dated 04/25/11 I believe) ICR from 

your primary aluminum reduction facilities (i.e., AlcoaWenatchee, Alumax of South Carolina, and Intalco Aluminum) 

indicated that the existing pitch storage tanks at your 

facilities are equipped with control devices. As part of the 

ongoing residual risk and technology review (RTR) project for 

the primary aluminum reduction source category I am collecting 

information on the costs associated with those controls.

Specifically, as a minimum, I need the following information for 

these

controls:
2

 The year the controls were installed;

1995

 The capital cost of the controls;

Fume capture and return system from tank 

cars, condensing tank, carbon Bed: Approximately $100,000

 The annual operating cost of the controls; and

Labor - $2,000

Equipment - $2,000

Filter media - $2,000

Total - $6,000

 The estimated emissions reduction attributed to the controls.

Removal efficiency has not been tested, but is 

estimated to be equal to or greater than 95%.

Please break down the annual operating cost information to 

indicate what portion is for labor versus materials (e.g., 

carbon).

Due to the tight schedule for this project please provide this 

information by this Friday, 08/12/11. If this is not possible, 

please contact me.

Thanks,
