Dear Mr. Powell,

In response to your visit to Greenwood Finishing #3 (71-6) on August 31 and September 1,
2017, 1 submit the following explanation of the incident, to the best of our knowledge.
On Wednesday, August 30, 2017 at 5:00 am, my farm manager conducted an irrigation event to
apply swine wastewater onto pulls 813 & 9B. This irrigation event lasted until 8:30 am. A second
event on the same two pulls was conducted from 9:30 am to 11:30 am. The field was dry
enough for the manager to pull the reels back out for a second, fast application. Our manager
observed no issues with these irrigation events on August 30th. My Operations Manager, David
Naylor, received a call on August 31st around 3:20 pm stating that a discharge of wastewater
had occurred in the creek near our farm. Our Technical Specialist, Curtis Barwick, received a
call at' 3:28 from Martin McLawhorn, NCDS&WC stating the same information. Both of these
men went to the farm and began walking ditches along with staff from Smithfield Foods to
determine if any waste had been released from our farm. It was determined that some
wastewater had entered a lateral ditch adjacent to pull 9B. This ditch empties into a main ditch
and it appeared that some wastewater may have had entered this main ditch which drains to
Sills Creek. By this time, you and Kristin Miguez had arrived and observed the ditches in
question along with Curtis, David and Kevin Weston from Smithfield. Also during your visit, farm
staff began pumping the pooled wastewater from the lateral ditch back into the waste storage
lagoon.
It appears that the second application on August 30th of approximately 22,000 gallons of
wastewater brought the 913 pull to field capacity and a portion of that wastewater ran into the
ditch. An exact amount cannot be determined but after much discussion, you determined that
approximately 15,000 gallons of wastewater was discharged.
To prevent future discharges of wastewater, irrigation operators will visually observe all lateral
ditches around all fields in which irrigation is being conducted so that any release can be
avoided or immediately found so that application can be ceased upon discovery. We are also
considering adding water control structures/fl ash board risers at the ditch outlets to contain any
water in the ditches.
I 'am enclosing a site sketch showing the path of the wastewater and a copy of the last waste
analysis performed from the lagoon. We engaged Environmental Chemists on September 1st to
sample and analyze the lagoon wastewater and await their results. A press release and public
notices have been distributed as per the permit requirements contained in Section III, 15 and
16.

We regret this incident took place and will make certain we more closely monitor all events and
notify DWR of any future discharges.
Thank you for your attention to this matter.
Sincerely,
Dean Hilton

Understanding the Waste Report* -additional information: www.ncaqr.qov/agronomi/pdffiles/uwaste.pdf& www.ncagr.gov/agronomi/pdffiles/wastequide.pdf
Nutrient concentrations and other data on this report are provided so that waste materials can be applied at agronomic rates, thereby supplementing or reducing fertilizer application and
preventing environmental contamination. In reading the Laboratory Results section, remember that materials with < 15% dry matter (generally liquids) are analyzed as received; all other
wastes are dried first Values in the Estimate of Nutrients Available for First Crop section are based on the type of waste and method of application you specify and reflect the fact that
only 40-60% of the nitrogen and 70-100% of other nutrients become available within one year of application. The remainder may or may not ever become available_
* ppm = parts per million; S = siemens; mS = millisiemens; T = trace (<0.005 lb/unit); EC = electrical conductivity; CCE = calcium carbonate equivalence; ALE = agricultural lime
equivalence; pH = acidity or basicity; DM%a = % dry matter [for semi -solid and solid waste samples, this value facilitates conversion of dry -basis concentrations (ppm) back to wet -basis of
original sample]; C:N ratio = carbon:nitrogen ratio.
