### TOPICS DISCUSSED AND ACTION TAKEN

On December 13 th I called the water department for DeKalb County ( http://www.dekalbeda.com/transportation

utilities/utilities ) and was given the phone number to the treatment plant (256

- 437

- 9001). I called the water treatment plant and was asked to email the information we are looking for with the EPA contract number. Chris Rose is the chief operator for the plant. Please see attached email communication.

On December 17 th I called the treatment plant and was told that Chris Rose would be in after 8pm. At 8:45pm I called the treatment plant and left a message for Chris Rose. I also followed up with an email.

On December 23 rd at 1pm, Mr. Rose returned my call. He apologized for the delay in getting back to me but he typically works night shifts. He had taken a second look at the DMR data I sent him and realized that flow was

incorrect. The flow should have been divided by 1,000 . Theref ore, flows should average .150 MGD, not 150 MGD. Mr. Rose also stated that their permit has an Aluminum limit of 10 mg/L and no flow limit except to report max and average discharges. The facility opened in 2007 and previously ran for about 12 hours a day but is now running 16

- 24 hours a day. It is a membrane filter plant and the backwash goes to pond 1 first which holds 1 million gallons. It then flows via a 250 foot pipe to a smaller pond that holds 256,000 gallons. The overflow from the smaller pond disc harges to the river. During the first few years of operation the facility had no overflow from the smaller pond and therefore no DMR discharges (the ponds weren’t full) . Mr. Rose stated that the first discharge to the river occurred in August 2009. This ex plains the lack of DMR data for the facility prior to 2009. Mr. Rose stated that he is available if we have any further questions.Email Communication with DeKalb Jackson WTP

Dear Mr. Rose,

Eastern Research Group, Inc. (ERG) under EPA Contract No. EP

- C

- 12

- 021,is e

- mailing you on
EPA's behalf to request clarification of 2011 discharge monitoring reports for DeKalb Jackson
WTP in Flat Rock, AL (AL0078557). Here is some background on what the information is used

for.

EPA reviews publicly

- available DMR data to fulfill its review obligation under Section 304(b) of the Clean Water Act (CWA). The CWA requires EPA to annually review and, if appropriate, revise its water pollution control technolog y

- based regulations, called "effluent limitations guidelines" or "effluent guidelines," that limit the discharge of pollutants to waters of the U.S. from various categories of industrial facilities. EPA is currently conducting its 2013 annual

review of exi sting effluent guidelines and potential industrial guidelines which may need to be included (see http://www.epa.gov/guide/304m/ for further information). EPA will discuss this review and the results in its 2013 Effluent Guidelines Program Plan scheduled for publication in the Federal Register in 2014. As part of the 2013 annual review, EPA is evaluating the data in discharge monit oring reports from 2011 and needs further information to complete the review.

We would like to obtain additional information on the following 2011 discharge data for aluminum for your facility. Our records show the following values were discharged:

Outfal l 001:

Date Aluminum

Concentration
(mg/L) Wastewater

Flow (MGD)

1/31/2011 4.03 159

2/28/2011 3.24 155

3/31/2011 3.42 146

4/30/2011 2.1 142

5/31/2011 1.39 151

6/30/2011 2.03 181

11/30/2011 2.54 147

12/31/2011 1.81 156

We appreciate your help in confirming if the above data are accurate, or if there are units errors

in the DMR data.

Please call me at (517) 515

- 1721 if you have any questions. If you would like to speak directly with EPA regarding this request, you can contact William F. Swietlik of EPA's Office of Water/Engineering Analysis Division by phone at (202) 566

Kimberly,

I pulled all my test results and discharge data logged for 2011. I confirm the information you have sent me is accurate. If there is anything else we can do to help let us know.

Thanks,

Mr. Rose,

I have the following additional questions for you regarding the DMR data. Some of them would
be easier to discuss over the phone so please don't hesitate to give me a call.

1. What is the typical flow rate for outfall 001? You confirmed data that was around 150 MGD
for 2011, however the data I have for 2010 has flows around 0.15 MGD. Is this change in flow
from year to year correct or is there a data error? If the data is correct, why has there been an

incr ease in flow?

2. The DMR data does not show discharges prior to 2010, has outfall 001 been constructed since
2009? Please provide a description of the outfall.

3. Can you describe your NPDES permit limits for outfall 001 for Aluminum and flow values? I f
possible, please provide a copy of your NPDES permit.

I greatly appreciate your help in determining if the DMR data is correct. Please don't hesitate to
give me a call at (517) 515

- 1721.

Thank you,
Kimberly
