# TOPICS DISCUSSED AND ACTION TAKEN

On January 23, 2014 at 2:02pm I called Carey Bullard (256

- 301

- 3541) of Nucor Steel Decatur LLC. He

expressed some trepidation about providing additional DMR and outfall data, and asked that I send an e

- mail

identifying myself in writing. I fo llowed up with an e

- mail communication later that afternoon describing the

project and the information that we were seeking.

Please see attached email correspondence for add itional information on the facility.

Subject: 2011 DMR Discharges

- AL0070068

Dear Mr. Bullard,

Thank you for speaking with me earlier. Eastern Research Group, Inc. (ERG) under EPA Contract No. EP

- C

- 12

- 021, is e

mailin g you on EPA's behalf to request clarification of 2011 DMR data for the Nucor Steel Decatur facility in Trinity, AL

(AL0070068). Please see below for further background.

EPA, Office of Water (OW) reviews DMR data to fulfill its review obligation under Se ction 304(b) of the Clean Water Act

(CWA). The CWA requires EPA to annually review and, if appropriate, revise its water pollution control technology

- based

regulations, called "effluent limitations guidelines" or "effluent guidelines," that limit the disch arge of pollutants to waters

of the U.S. from various categories of industrial facilities. EPA is currently conducting its 2013 annual review of existing

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 sometime in 2014.

As part of the 2013 annual review, EPA is evaluating 2011 DMR data and needs further information to complete the

review. Specifically, we have the following questions:

- Please confirm the aluminum concentration and flow values for all outfalls in the 2011 DMR data (see attached).



## - Please provide a description of all outfalls.

We appreciate your help in interpreting DMR data correctly. Please call me at (703) 633

- 1610 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

- 1129 or by email:

swietlik.william@epa.gov

Thank you,

Any chance you could pull 2012 numbers as well? They will serve as a good comparison.

## Attached is the analysis from the next rain event on 1/26/2012 that shows the Al concentration at 0.463 mg/L. Another

note that you all do not know and can't see is that this outfall is located m iles from any tributaries or navigable waters. It

travels on our property through several ditches and swamp areas where the Al would fall out before ever reaching a

tributary.

As for providing additional data, I am extremely busy and unfortunately cannot s pare more time assisting you. I hope

that this information aids you in accomplishing you goal.

Respectfully,

Carey Bullard
