General Subject: Nitrate Compound Discharges Reported to TRI in 2009



### TOPICS DISCUSSED AND ACTION TAKEN

Background Information:

Mark Carnes 308

- 324

- 8158

– Wastewater Treatment Contact (NPDES Contact)

Pounds of Nitrate Compounds Discharged in 2009 TRI: 4,991,531

BOE: M2

Questions to discuss:

1. Can you confirm the nitrate compounds discharges for 2009?

2. Are the discharges based on actually sampling data ?

3. Can you confirm the difference between DMR2009 discharges for total nitrogen, nitrate total = 0 in

2009 and TRI ?

4. Are there other nitrate discharges (stormwater) that aren’t covered by the NPDES Permit?

Telecon:

I contacted Mark Carnes of Tyson Fresh Meats, Inc. on Friday, March 16, 2012 at 11:30 am. Mark Carnes

stated that I should contact Chris Loeg (605

- 235

- 2003) for further information on TRI reporting. However, he

did state that the 2009 discharges would probably be much higher than 2010 or more recent data because of the

changes to the wastewate r treatment system (simulation of an anoxic system, see below for further detail) as a

result of the ELG total nitrogen limitation.

I called Chris Loeg at 11:40 am, and explained that I’m calling to confirm 2009 TRI discharge data (nitrate

compounds) for the Tyson Fresh Meats, Lexington NE facility (NE0123501). He stated that the amount of

nitrate compounds reported to TRI in 2009 were 4.99 million, confirmed the pounds of nitrate in the EPA

database. He stated that the nitrate load is calculated using the average daily nitrate/nitrogen (factoring up to

nitrate) concentrations from bench scale and lab tests. Mr. Loeg stated that bench samples are collected three

times per week.

Mr. Loeg stated that the 2010 nitrate compound load in the 2009 TRI database i s lower (3.4 million) because of

the changes to the wastewater treatment system. These changes included changing two complete mixing basins

(previously part of the extended air basin) to an on/off system, so aeration is occurring half of the time. This

cre ates an anoxic environment, and achieves denitrification and nitrification at the same time.Need to return call by / at/between and

. Signature: Additionally, I asked why the 2009 DMR data was reported as “0” mg/L. From looking at the old and new

permits, it was determined that total nitrogen reporting was not required until the October 2010 permit.

Therefore, there was no total nitrogen data for the facility prior to 2011 (available in OTIS). The previous

permit only had limits for flow, BOD, O&G, TSS, pH, and fecals.

Mr. Loeg stated that he did not handle the Tysons Joslin, IL facility (other top discharger). However, the contact

is Ms. Ras t e s sin (sp?)

Called and left a message for Ms. Kim Ra t ses s in on Monday, March 26, 2012 at 1:20 PM.

Ms. Rastessin left me a message Monday, March 26 at 2:15 PM asking me to return her call.

I called Ms. Rastessin back on Tuesday, March 27, 2 012 at 11:10 am and left a message.

Returned Ms. Rastessin’s call from March 28, 2012 (11:15 am) on March 29, 2012 at 10:00 am.

Ms. Rastessin stated that she would look into the discrepancy between the 2009 TRI and DMR data. She stated

that a possible sce nario is the calculations/molecular weights for the different “nitrate compounds” and “nitrate,

total nitrogen (as N)” in the different database. Additionally, she stated that they recently received their new

permit from the state implementing the new tota l nitrogen limits from the ELG. They are currently working

with IEPA to determine if any additional treatment is necessary to meet the limits.
