Nathan,

I appreciate your efforts to respond to these questions about the Miami Fort FGD data, especially

given the circumstances Duke Energy has been dealing with this past year. Please keep in mind that

these questions are intended to allow us to use the data you’ve provided to the extent possible and

that if we cannot resolve these issues may be constrained in that regard. Given our court-ordered

deadline for taking final action on the effluent guidelines, the timeliness of your response is critical.

Also, please be aware that we will be sending you some follow-up questions related to the other

data you provided. I hope to get you those later this week.

Regards,

Ron

Ron,

We have been working to pull this information together.  We just have a couple of more lab reports

to track down and hope to provide the information by the end of next week.

Sorry, we have not been able to provide this information sooner, but we have a lot of commitments

at the moment.

Thanks,

Nathan Craig

Good morning Nathan,

I’m following up on a few items from our June 2nd call regarding the Miami Fort data.  According to

my notes, you’re checking into the following:

1. Confirm whether the research lab result for arsenic of 4.34 ug/L on 6/28/11 is a J-value.

2. Provide additional lab reports for the arsenic data you submitted (see question #5 of the

attached file).

3. For arsenic data on 7/31/12 and 8/1/12, the data submitted with comments show nondetect

at 10 ppb, while the spreadsheet provided in response to EPA’s data request shows

nondetect at 20 ppb. Please confirm which RL is correct.

4. As I recall, during the call Duke staff suggested some of the arsenic data may have been

analyzed at labs that are not certified. If so, please specify which data this applies to.

5. Please provide the lab report for the mercury result of 343 ng/L on 11/2/10.

6. Confirm whether the mercury result of 0.5 ng/L on 4/2/13 is nondetect (see question #12 of

the attached file).
7. Please provide the lab report for total mercury on 9/1/09 and 9/21/09 (see question #14 of

the attached file).

8. Confirm the dilution factor calculations for outfall 601 on 9/3/13 for units 7 & 8 (see

question #18 of the attached file).

9. Please provide the additional lab reports for the mercury data you submitted (see question

#20 of the attached file).

If possible, it would be great to wrap this up by the end of the week.

Regards,

Ron
