TJ,

We have reviewed the subject notes and except for the following comments the notes accurately reflect conditions at the time of the

site visits. As to whether these notes need to be classified a s Confidential Business Information (CBI), since all of the information

contained in the notes was submitted at one time or another to the state permitting authorities, the notes do not need to be treated

as CBI.

Fort Martin Site Visit

* Page 1

- Plant Overview

- Allegheny Energy Supply's ownership of Fort Martin Power Station was transferred over to Monongahela Power Company

as part of the funding for FGD construction. I don't have the exact date, but believ e that transfer occurred prior to

your February 2010 site visit.

- EPA Region III's letter required testing for sulfates, not sulfites as listed in the notes.

* Page 4 Highlighted question

- The cutoff chl oride concentration for determining where to send the primary hydrocyclone overflow is 10,000

- mg/L. Below

10,000

- ppm overflow goes to reclaim tank, greater than 10,000

- ppm chloride level is sent to the secondary hydrocyclone.

* Page 6 Highlighted questi on

- The design mercury level would be the level in Table 2

- Professional Guarantees for the FGD Wastewater Treatment

System. The permitted mercury limit is imposed at the combined wastewater outfall 002 (FGD

- WWTP and Station's other

"l ow volume wastewater" treatment system). The limits are 0.0244 

### μ g/L monthly average and 0.049 

### μ g/L daily

maximum, however, these limits where stayed pending the outcome of our permit appeal and have not yet been resolved.

- percent of the wastewater flows from Hatfield's

wastewater treatment lagoon system.

* Highlighted question on page 3

- Filtrate from the vacuum filters is transferred to the reclaim tank.

* Page 5

- second bullet

- As clarification, the average daily discharge flow from the FGD

- WWTP (IMP

- 306) is typically about 120

- gpm.

* Page 5

- last bullet

- Outfall 006 is also monitored for total dissolved solids (TDS) and has lim its at Outfall 006 for oil & grease, mercury, and

TDS. These parameters were omitted from the notes.

Please don't hesitate to call if you have any questions regarding this information.

Thanks,
