TOPICS DISCUSSED AND ACTION TAKEN

On December 11, 2013 at 3:02pm I called Dana Waits (615-532-1171) and left a message asking her to return 

my call.

Dana returned my call on 12/12/13, but I was out of the office. I called her back on 12/13/13 and alerted her to 

my availability to talk the following Monday.

On December 16, 2013 at 2:22pm I spoke with Dana. I agreed to send her our DMR data and ask her to verify 

the measured values.

On January 7, 2014 at 10:14am I left a message with Dana stating that I would send additional lead 

concentrations for her to verify.

On January 16, 2014 at 3:11pm I called and left another message with Dana, asking for any additional 

expediency that they could provide. I also called the main office line and requested additional support; they 

suggested sending someone to TN to look at the documents.

On January 17, 2014 at 1:51pm I called the facility directly to discuss our questions (931-552-4200). I was 

directed to William (Chad) Crocker’s voicemail, where I left a voicemail.

On January 20, 2014 at 12:23pm, Chad returned my call. We briefly discussed the on-site sampling procedure 

(twice a month for cadmium and quarterly for lead), as well as the various outfalls on-site. There are a total of 

five outfalls on-site; two are used for process water discharge and the other three are used for stormwater. 

Outfall 001 is discharge of process water that has been run through a metals recovery treatment plant. Outfall 

002 is from a filter backwash pond that is used to contain overflows. SW3 is the primary stormwater drain for 

the facility. SW4 is the stormwater outlet for the raw material transfer area of the facility. SW5 is used to 

discharge water that accumulates due to the facility location being at the bottom of a hill. The contact requested 

I send an e-mail with any additional questions.

On January 24, 2014 at 4:25pm, Chad e-mailed me back with a partial confirmation of the lead data and some 

of the cadmium data.

On January 27, 2014 at 9:34am, I called Chad to follow up on the information he sent and to ask some 

additional questions. I left a voicemail and sent an e-mail as well. He returned my call at 11:47am and told me 

that, plus or minus a slight amount, he had roughly the same values for the mass of discharge for both cadmium 

and lead. He also confirmed that there were discharges out of the SW outfalls throughout 2007, 2008 and 2009 

and would send reports that correspond to those outfalls, and that it was possible there was miscommunication 

with the state of TN based on changes in reporting software and methods.
Please see attached e-mail correspondence for additional information on this facility.

Sorry again for the delay. I could go as far back as Aug 2008 in my records here. The program we used before that to 

submit the data is old and does not work on my computer anymore. But I did get what I could put into a spreadsheet 

format.

Good morning, Chad;

I'm following up on our conversation last week to see if you had a chance to pull together the 2007, 2008 and 2009 DMR 

information for outfalls 001, SW3, SW4 and SW5. Please let me know if there are any questions or if I can assist in any 

way.

Thanks!

Good morning Chad!

I just wanted to follow up to see if you had any additional questions or were able to take a look at this information yet.

I'm available by phone or e-mail all day today.

Thanks again for your help.

Good morning, Chad;
Again, my apologies for indicating the wrong units for cadmium measurements in the spreadsheet I sent you. Please 

see the attached, updated spreadsheet. Our report comes from the DMR database, which consists of 

information reported by the state of TN to ICIS. The state of TN gets their data from the DMR reports that are sent to 

them by discharging facilities. As you can guess, there's a lot of opportunity for error as the information is passed among 

so many different parties.

I'll be available most of the week to discuss and follow up on some of the questions from my voicemail.

Thanks again!

Julia

1. The flow data and the cadmium data for the stormwater outfalls matches my records. The cadmium data for outfall 

001 does not match anything that I have. Is this a calculated value in the report that you ran? We report the data for 

001 in units of lb/d.

2. All of the lead data in your attached spreadsheet is correct. I have compared it to my sheets I use for reporting.

3. The site has been reporting cadmium and lead discharges for many years, as far back as my records are. We began 

reporting data into netDMR in 2010.

4. Outfall 001 – Treated water from our on-site Metals Recovery process that discharges into the Cumberland River 

through a closed pipe. The water is sampled by automatic composite sampler prior to discharge into the river. SW3 –

Stormwater runoff that drains from the main production area of the facility through underground storm sewer system.

SW4 – Stormwater runoff that drains from the “Materials Handling” areas, including concentrate/oxide storage, covered 

conveyor systems, and truck unloading operations. SW5 – Stormwater runoff that drains from ancillary areas of the 

facility, including parking lots, maintenance shop, drainage from up-gradient residential, and truck loadout.

If there is anything else you need, let me know. Sorry for the delay.

Hi ChadI just wanted to follow up and make sure you had received this e-mail. Do you have a rough idea when this information 

might be available?

Dear Mr. Crocker,

Thank you for speaking with me earlier. Eastern Research Group, Inc. (ERG) under EPA Contract No. EP-C-12-021, is emailing you on EPA's behalf to request clarification of 2011 DMR data for the Nyrstar Clarksville facility in Clarksville, 

TN (TN0029157). Please see below for further background. 

EPA, Office of Water (OW) reviews 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 technology-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 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 cadmium discharge values (Outfalls 001, SW3, SW4 and SW5) for the 2011 DMR data (see attached).

- Please confirm the lead discharge values (Outfalls SW3, SW4, and SW5) for the 2011 DMR data (see attached).

- When did the facility start monitoring for cadmium and lead discharges?

- Provide a description of outfalls 001, SW3, SW4, and SW5.

- If readily available, please send the 2012 and 2013 cadmium and lead DMR data.

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,

Julia
