General Subject: 2013 TRI PAC Discharges for Graftech International Holdings, Inc., Columbia, TN

TOPICS DISCUSSED AND ACTION TAKEN

On April 14th 2015 at 11:36 am I called Ms. Julia Aslinger (931-381-4346) and left a message in the voicemail 

box of Tommy Underwood.

On April 22nd, 2015 at 10:32 am, I left a message in the voicemail box of Tommy Underwood again requesting 

a contact for discussing TRI wastewater discharges.

On April 23rd, 2015 at 3:18 pm, I called the Graftech Columbia office (931-388-1410) and was transferred to 

Beverley Philpot’s voicemail box as a contact for wastewater discharges, but was told she would not be in the 

office until Monday. I left a message requesting her to call me back.

On April 28th, 2015 at 4:31pm, I called the Graftech Columbia office and asked the receptionist for Beverley 

Philpot’s direct number. The receptionist explained Ms. Philpot goes back and forth between the Columbia and 

Lawrenceburg offices. Columbia, TN: (931) 380-4305. Lawrenceburg, TN: (931) 762 – 7101 ext 7101

On April 29th, 2015 at 1:31pm, I called Ms. Philpot’s Columbia office number. She confirmed the 394 lbs and 

explained how the facility calculates their PAC discharges from an estimation of the percent of PACs in the 

TSS of the wastewater. The facility estimates this as 4%.

Values Ms. Philpot shared:

 6.4 mg/L – average concentration of TSS in wastewater for 2013

 0.504 MGD – average flow for facility

 4% - estimation of percentage of PAC in TSS based off of process knowledge

First the facility finds the pounds of TSS for the year:

6.4 mg TSS

L

∗

504,000 gal

day ∗ 365 days ∗

3.79 L

gal ∗

2.2lb

1,000,000 mg

= 9816.69 lb TSS

Then the facility uses process knowledge to figure out the pounds of PAC

9816.69 lb TSS ∗ 0.04 = 392.668 lb PAC

On April 29th, 2015 at 2:38pm, I called Ms. Philpot’s Columbia office number and left a message asking if there 

was a note in the dataset about if the facility knew which specific PAC’s it discharge or on the increase in PAC 

discharges from 2012 to 2013.

On April 29th, 2015 at 6:02pm, Ms. Philpot returned my call and left a message.

On April 30th, 2015 at 9:16am, I returned Ms. Philpot’s call. She did not have a comment on the distribution of 

PACs for the facility and stated there was no note in the data set she was looking at. She did have a comment on 

the production differences from 2012 to 2013. She stated that there was an uptick in production. I left my email 

with Ms. Philpot to send the data or any information she may find concerning the PAC discharges/distribution.

On May 13th, 2015 at 9:15am, I called Ms. Philpot to talk about the PAC sampling data GrafTech provided in 

2010 which was able to list individual parameters. Ms. Philpot said she believe this was still the most recent 

sampling data for the facility and should be consistent with what the facility is discharging now.
