GENERAL SUBJECT : FGD Systems and FGD Wastewater Treatment System Operation and Verification

TOPICS DISCUSSED AND ACTION TAKEN

On Wednesday, December 2, 2009 at 9:45 AM I contacted Mr. Tim Lohner. I explained to Mr. Lohner that I was calling to confirm the operation of the FGD syst ems and FGD wastewater tr eatment systems for the Mitchell, Mountaineer, Amos, and Card inal. I began the conversation disc ussing the operations at the Mitchell

Plant.

Mitchell Plant

Mr. Lohner confirmed that limestone forced oxidati on systems are operated on Units 1 and 2 and that no additives are added to the FGD systems. Mr. Lohner also confirmed that Units 1 and 2 both operate SCR systems and a Trona injection system. Additionally, Mr . Lohner stated that the SCRs operate year round.

Mr. Lohner said that that no new units ar e planned to begin operation in 2010.

Mr. Lohner confirmed that there have not been any si gnificant changes to the FGD wastewater treatment system; however, he stated that the plant could be maki ng changes to add organosulfide to the treatment system, but he would need to confirm the plan ts current plans. In a follow-up e-ma il, Mr. Lohner stated that the plant will have an operational organosulfide tr eatment system in place by May 4, 2010.

Mr. Lohner confirmed that the FGD wa stewater treatment system only tr eats FGD scrubber purge wastewater and that the system was designe d by the company CH2MHill.

Mr. Lohner explained that the FGD wast ewater treatment system does not targ et any specific metals but is used

to remove solids from the wastewater. Mr. Lohner stated that he was not aware of any internal limits on the

FGD wastewater treatment effluent that is transf erred to the bottom ash pond.

Mr. Lohner explained that the plan t is not planning to make any changes to the operation of the FGD wastewater treatment system (other than adding the organosulfide treatment).

Mr. Lohner stated that the typical fl ow rate of the FGD wastewater trea tment system has not changed since sampling for the detailed study.

Mr. Lohner said that he was under th e impression that the FGD wastewat er treatment system operates and discharges in batch mode, because the treatment system receives intermittent transf ers of FGD scrubber purge.

Mr. Lohner stated that he will get back to me w ith additional information.Mr. Lohner explained that there could be possible outages scheduled between April and November 2010; however, he did not know the specific date s times for the outages. Mr. Lohner st ated that he will get back to me

with additional informati on regarding the outages.

Mr. Lohner stated that he doesn’t know as much info rmation regarding the FGD sy stem and FGD wastewater treatment system operations at Mountaineer, Amos, and Cardinal, so he tried cont acting the individual plant contacts at each of the plants, but none of the contacts were available. Mr. Lohner asked that I send him the questions for each of the plants via e-mail so he can pass them along to the plant contacts to fill out the

information.
