Ron, Attached is the information that y ou requested regarding the influent and effluent data of the pilot-scale FGD wastewater treatment evaluation
at Plant Yates.

Please let me know if y ou have any questions.

Sincerely,

Hi Donna,

Thanks for taking the time earlier to day to discuss EPA's request for data on the recent pilot test at Plant Yates.

You asked if EPA would be amenable to waiting until the end of May to receive the pilot test data, so that Southern Company (Georgia Power) could at that time provide the t echnical report that IDI and your company will be preparing for the pilo t testing. I agree that the data
will be more useful and understanda ble when evaluated in conjunction with the report. Therefore, EP A is extending the deadline for submitting the data (described in the Jan 28, 2009 email) and the associated technical report to May 30, 2009.

During our call, we also discusse d Southern Company delivering an interim product that would provide some insight to the efficacy of the pilot treatment unit. Specifically, I asked for graphs showing concentration data for (1) influent to the physical-chemical unit; (2) effluent from the physical-chemical unit; (3) influent to the biological treatment unit, if different from th e effluent from the phys-chem unit; and (4) effluent from the biological treatment unit. I would like to also add the sample point for the effluent from the ion exchange treatment unit. For this interim product, the analytes of most interest are total and dissolved metals (arsenic, chromium, mercury, and selenium), nitrate-nitrite, ammonia-n itrogen, TKN, and BOD. Please let me know what you find out about the availability of these data. I would appreciate receiving this interi m product by March 31, 2009.

Hi Ron, I need to talk to you about this request. When would be a good time to call you?

Thanks,

Donna

Hi Donna,

I'm writing to follow up on our January 16 conference call about the Infilco Degremont pilot treatment system undergoing testing at PlantYates. As we discussed following that call, EPA is interested in learning more about the design/operati on of the treatment system for the purpose of our detailed study of th e steam electric power generating point source category.

EPA requests Southern Company / Geor gia Power to provide wastewater sampling data collected throughout th e testing of the pilot treatment system, to encompass all phases of the testing program and all parameters for which samples were an alyzed. If possible, please provide
these data in electronic format (MS Excel spreadsheet, MS Access database, or similar format) and incl ude relevant information such as sample location, date sample co llected, analytical method used, sample-specific minimum detection le vel and minimum quantitation level, and flow rates. Please provide thes e data by Friday, February 27, 2009.

Should you choose to submit the data by postal or overnight mail, please be sure to use the appropriate address:

U.S. Postal Mail
Ron Jordan Engineering and Analysis Division (4303T)
Office of Water U.S. Environmental Protection Agency 1200 Pennsylvania Avenue, NW Washington, DC 20460

Federal Express or simi lar overnight/courier service
Ron Jordan U.S. EPA / Office of Water / Engineering and Analysis Div. EPA West/Connecting Wing (Room 6233W) 1301 Constitution Ave., NW Washington, DC 20004

As always, please don't hesitate to contact me if you have any questions.

Regards,

Ron
