TOPICS DISCUSSED AND ACTION TAKEN 

Communications between Denise Wood, Mohawk Industries and Lauren Wingo, ERG: 

I called Denise Wood on September 2, 2010 at 4:45 pm. Ms. Wood asked that I send her an e-mail with the 

requested information to denise_wood@mohawkind.com. 

I called Denise Wood on September 7, 2010 at 4:15 pm and asked if I could also e-mail her about the Oak River 

facility and she agreed. 

I called Ms. Wood on September 9, 2010 at 4:30 pm to follow up on the e-mails I had sent her. Ms. Wood said 

that she has contacted facility engineers at each of the two facilities but has not received the information from 

them. I notified Ms. Wood that EPA was hoping to have the information by Friday, September 10, 2010 but Ms. 

Wood indicated that she would not have the information until next week, most likely. 

I left a message for Ms. Wood on September 15, 2010 at 4:05 pm asking that she reply all in her response to my 

e-mail, since I would be out on vacation the following week. 

Communications between Denise Wood, Mohawk Industries and Elizabeth Sabol, ERG: 

I called Ms. Wood on Wednesday, September 22 at 9:30 a.m., to follow up with her regarding the Mohawk emails sent September 7 requesting information for two facilities: Oak River and Lyerly Plants. Ms. Wood stated 

that the information in the e-mail for the Mohawk Lyerly Plant was correct and that she would send an e-mail

confirming the data. Ms. Wood also stated that she would contact the Oak River Plant to request the data be 

confirmed and sent as soon as possible. 

I called Ms. Wood back to get insight on where the sulfide in the wastewater was originating. Ms. Wood stated 

that sulfide is present in the wastewater due to boiler cleaning chemicals and chemicals used to treat intake 

water for hardness. 

Please see the attached e-mails and documents for further information.

Subject: Re: DMR Clarification Needed for GA0024104 

Good afternoon, 

The Mohawk Lyerly facility's discharge permit limits for sulfide are 25 

pounds/day daily average and 50 pounds/day daily maximum, to be sampled 4 

times per year. The sulfide concentration is < 1ppm and most likely is 

coming from boiler and water treatment chemicals used at the facility. 

Sincerely...Denise

 DMR Clarification Needed for 

 GA0024104 

 

Dear Ms. Wood, 

Thank you for taking the time to speak with me the other day. I am writing 

to follow up on our conversation regarding Mohawk Industries' Lyerly Plant 

(GA0024104) and explain more about the information I am looking to collect. 

I work for Eastern Research Group, Inc. (ERG) as a contractor to EPA under 

EPA Contract No. 68-C-02-095. Here is a background of what this information 

is being used for. 

EPA reviews publicly-available DMR data to fulfill its review obligation 

under Section 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 2010 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 2010 Effluent Guidelines Program Plan 

scheduled for publication in the Federal Register in December 2010. As part 

of the 2010 annual review, EPA is evaluating the data in discharge 

monitoring reports from 2008 and needs further information to complete the 

review. 

We would like to verify the information we have on record for the average 
sulfide discharge. Our records show the following: 

Outfall 0A1: 

- Jan 08: 6.08 kg/day 

- Apr 08: 8.31 kg/day 

- Jul 08: 7.61 kg/day 

- Oct 08: 2.93 kg/day 

Average flow range: 0.723 MGD to 1.659 MGD 

We appreciate your help in confirming the above data are accurate and if 

any of the data were reported as non-detect. We would also like information 

on the measured sulfide concentrations for 2008 and on the source of 

sulfides in the wastewater. Also, what is the basis for the sulfide permit 

limit? Can you provide the sulfide concentration that was used to calculate 

the sulfide quantity limit? 

We appreciate your help in verifying this data and answering our questions. 

You may return the requested to me via email or by phone at (703) 633-1692. 

If you would like to speak with EPA directly with regarding this request, 

you may contact William Swietlik by phone at (202) 566-1129 or by e-mail: 

swietlik.william@epa.gov. 

Thanks,

Subject: Re: DMR Clarification Needed for SC0001996 

Good afternoon, 

The Mohawk Oak River plant's December 2008 AVG and MAX toxaphene discharge 

concentrations were both <0.0005 (DL). 

This chemical is not used as a raw material or in any other chemicals used 

at the facility, so the origin is unknown during the few months when 

present above the 0.5 ppb detection limit.

 DMR Clarification Needed for 

 SC0001996 

 

Dear Ms. Wood, 

Thank you for speaking with me again over the phone today and offering to 

help verify information for the Oak River Plant (SC0001996), in addition to 

the information you are verifying for the Lyerly Plant. This information 

will be used for the same purpose under EPA Contract No. 68-C-02-095. 

EPA reviews publicly-available DMR data to fulfill its review obligation 

under Section 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 2010 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 2010 Effluent Guidelines Program Plan 

scheduled for publication in the Federal Register in December 2010. As part 

of the 2010 annual review, EPA is evaluating the data in discharge 

monitoring reports from 2008 and needs further information to complete the 

review. 

We would like to verify the information we have on record for the average 

and maximum toxaphene discharges. Our records show the following: 
Outfall 001: 

Average Toxaphene Concentration: 

- Jan 08: <0.0005 mg/L 

- Feb 08: <0.0005 mg/L 

- Mar 08: <0.0015 mg/L 

- Apr 08: 0.0012 mg/L 

- May 08: 0.0005 mg/L 

- Jun 08: <0.0005 mg/L 

- Jul 08: <0.0005 mg/L 

- Aug 08: <0.0005 mg/L 

- Sep 08: <0.05 mg/L 

- Oct 08: <0.0005 mg/L 

- Nov 08: <0.0005 mg/L 

Maximum Toxaphene Concentration: 

- Jan 08: <0.0005 mg/L 

- Feb 08: <0.0005 mg/L 

- Mar 08: <0.0025 mg/L 

- Apr 08: 0.0025 mg/L 

- May 08: 0.0005 mg/L 

- Jun 08: <0.0005 mg/L 

- Jul 08: <0.0005 mg/L 

- Aug 08: <0.0005 mg/L 

- Sep 08: <0.05 mg/L 

- Oct 08: <0.0005 mg/L 

- Nov 08: <0.0005 mg/L 

Average flow range: 0.070074 MGD to 0.164852 MGD 

We appreciate your help in confirming the above data are accurate. We would 

also like to know if the April and May 2008 toxaphene concentrations were 

below the detection limit? Also, we do not have toxaphene or flow data for 

December 2008. Were they measured? If so, can you provide the data for 

December 2008? Additionally, we would like to know the source of the 

toxaphene in the wastewater. 

Again, we appreciate your help in verifying data and answering questions 

for both the Oak River and Lyerly plants. You may return the requested 

information to me via email or by phone at (703) 633-1692. Again, if you 

would like to speak with EPA directly with regarding this request, you may 

contact William Swietlik by phone at (202) 566-1129 or by e-mail: 

swietlik.william@epa.gov.
