### , I called Mr. House and left a message.
On January 7 th 

### , I called Mr. House. He stated that the facility is a RCRA Corrective Action Site and is no longer operating. They have been doing extensive construction on the site to cap the contaminated soil and are currently in year 4 of construction. Mr. House stated that construction should be completed soon, but at times during construction levels of dioxin were detected in storm water samples. These dioxin levels were listed in the D MR. Mr. House requested an email with our credentials so he could confirm the sampling data. See attached email correspondence.
[In Mr. House’s email correspondence, he requested a meeting with ERG and EPA. Two separate calls were set up but both had to b e canceled. Mr. House provided additional information via email instead of on the call.]

### Solutia Email Communication:

To: William Swietlik From: Michael House CC: Kim Wagoner, Kimberly Bartell Date: Friday 1/30/15 12:34 PM Subject: Re: [I] 2013 DMR Clarification for Dioxin Discharges
Please see attached and responses below.
I have included all three pages of the text y ou mention. This was part of an introduction to an NPDES permit modification request to extend the construction completion deadline to August 15, 2015. The majority of this time is necessary to complete final design, installation and start

- up of the low vo lume groundwater pump and treat system that will maintain inward hydraulic gradients at the slurry wall areas. The only area left to cover in the Outlet 001 drainage area is the containment channel prior to outfall. The channel has been lined. The sediment s in the channel will be contained, the channel cleaned, and the clean soil cover installed. This area is approximately 2

- 3 acres and should be completed in the spring. We are currently shut down due to wet winter conditions.

To: Michael House From: William Swietlik CC: Kim Wagoner, Kimberly Bartell Date: Tuesday 1/27/15 10:39 AM Subject: Re: [I] 2013 DMR Clarification for Dioxin Discharges

Michael:
Thanks for letting us know.
Maybe we can forego this call altogether if you could provide us a little more information about the facility.
(The attachment you sent this morning summarizing activities at the facility appeared to include only page 1 of three pages, and does not addr ess all our information needs.)
Or, we are still happy to do a call if you'd like.
In the call today, we had planned a few questions to ask you if you did not cover them in your presentation.
The questions we had are:
1. What is the schedule for comp letion of the remediation activities following the noted delays?
2. Could you explain for us what industrial operations took place at the facility prior to remediation that caused the TCDD contamination?
3. Are the TCDD discharges all storm water relat ed?
4. Do you expect the TCDD discharges to cease with the completion of the remediation activities? If so, when do you anticipate this will happen?
5. Could you provide us your 2014 DMR data for the TCDD discharges? (this would help us confirm that the data in the DMR Loading Tool is correct, which seem to indicate that discharges of TCDD have decreased since 2013).
In sum, Michael, we are trying to fully understand what is happening (and will happen) at the facility so we can possibly remove it from f

urther review under our Clean Water Act, Section 304m annual reviews.If the site remediation is expected to reduce or eliminate the TCDD discharges over the next couple of years this would be very useful to know for our analysis.
Thank you,

Bill

Kimberly, William, Kim,
My apologies but something has come up and I won’t be able to make the call. We’ve probably already gone to to o much trouble already on this. I had simply wanted to advise of the site conditions in 2013 that resulted in TCDD in site stormwater. As I mentioned the site was undergoing extensive remediation earthworks. This work is being performed under the oversight of EPA Region 3, the USACOE, and the WV DEP. Extensive best management practices were implemented to limit, to the degree possible, turbidity in the stormwater. The caps and covers over the area the area of the site which drains to Outlet 001 are complete and we have had multiple, consecutive sampling events resulting in non

detects for any site constituents, including TCDD. Of course, this was the objective of the containment remedy. I’ve attached again an excerpt from a recent submission to the WV DEP th at describes what actions are taking place at the site. This four year construction project is nearly complete.
Sorry for the short notice.
Kind regards,

Kimberly,
The data in your attachment appears to be correct. I was wondering if it would be possible to have a brief discussion with you and Mr. Swietlik. I wanted to make sure the data was being looked at in the context of site conditions at the time of collection, that is, active remedial construction. I’ve attached a page of text from a recent submission to the WV DEP that is a good summary of what we’ve done and where we are.Thanks, Michael House Remediation Services Manager Solutia Inc.

Dear Mr. House,
Thank you for your time on the phone today. 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 2013 discharge monitoring reports for Solutia in Nitro, WV (WV0116181). Please see background information below.
EPA reviews publicly

- available DMR data to fulfill its review obligation under S ection 304(b) of the Clean Water Act. 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 2015 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 2015 Effluent Guidelines Program Plan scheduled for publication in the Federal Register sometime in 2015 or 2016. As part of the 2015 annual review, EPA is evaluating the data in discharge monitoring reports from 2013 and needs further information to complete the review.
We would like to obtain additional information on 2013 discharge data for Solutia, our records show the 2,3,7,8

- Tetrachlorodibenzo

- p

- dioxin values in the attached spreadsheet were discharged from outfall 001. We appreciate your help in confirming if the attached data are accurate, or if there are units errors in the DMR data. Additionally, please provide any background information on the facility that would aid in understanding the discharges.

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 Wi lliam F. Swietlik of EPA's Office of Water/Engineering Analysis Division by phone at (202) 566

- 1129 or by email: swietlik.william@epa.gov
