Good Morning, Elizabeth: I think I am good with my comments below but I have a Favor/Request to

make.

We are no longer using the name ASHCON for our Remote Submerged Scraper Conveyor, RSSC.

I ask that the word ASHCON be removed from your summary of September 30. In most cases, you

can just strike the name but in some cases you need to replace it with RSSC or the full wording.

Let's talk so I can explain further?

Thanks,

gary

Good Afternoon, Elizabeth:

Here are some quick answers after my first read through of your three attachments:

1) You ERG Memorandum of September 30, 2015

Page 2. Your Comment E1: No grinder is needed for pure fly ash. Small grinders are used for

Economizer ("Popcorn" ) ash and large grinders are always used for bottom ash.

Page 4. Your Comment E2: While there are no CBPG ASHCON installations, there are several

operating systems in this remote equipment category. The TVA system at Bull Run and most future

TVA remote system use Clarifiers.

 There is a remote system at KU Ghent that does not use a clarifier and merely

drains to a sump, for now. The SCE&G installation at Wateree does not use a clarifier.

Page 4: Your Comment E3: No known installations of a remote conveyor use a heat exchanger. All

have nearby spare conveyors that can serve as a reservoir or bath to help cool water down if needed.

 The same three sites above (TVA Bull Run, KU Ghent and SCE&G Wateree) all

do not use heat exchangers. I AM bidding a new SSC job now that uses them.

Page 4: End of paragraph on Remote SSC: next to last line: "experience that many plants are holding

off on bottom ash system conversions until the CCR rule........

Page 6: Your Comment E4: Yes, you can include this document as a CBI.
Page 6: Your Comment E5: Yes, the 30 ppm was the goal for discharging into the environment but it

still helps lower wear in a closed loop system. For a closed loop recycle system, I'd want to be

between 200 and 400 ppm to keep the wear down.

Page 6: Paragraph 3.0 second paragraph. Plant name is La Cygne, not La Cynge.

Page 6: Your Comment E6: Yes, you can include these documents as a CBI.

Page 8: Third Line: ASHCON not AHSCON.

I'll let you know what I else I find,

Gary

Mr. Mooney,

A representative of Eastern Research Group (ERG), a contractor to the Environmental Protection Agency (EPA),

contacted and met with Clyde Bergemann Power Group (CBPG) several times starting in January 2014 to gather

information for the Agency's rulemaking. Attached please find the draft notes from our correspondence and

associated attachments summarizing the information discussed and subsequent email communication. Please

review the documents paying particular attention to accuracy and any potential confidential business information

(CBI) concerns. My understanding is that none of the information included in these files is CBI. If this assumption

is incorrect, please let me know.

Following receipt of your comments, EPA will finalize the notes for inclusion in the public record associated with

the revisions to the steam electric effluent guidelines.

EPA requests that you provide comments on the draft call notes by September 18, 2015. If comments are not

received by this date, EPA will assume that the notes are accurate and that there are no CBI concerns regarding

the information included in the notes. You may send your comments to Phillip Flanders via e-mail (if not CBI) at

flanders.phillip@epa.gov, or by mail to:
