Attachment to NCG500 Renewal Form for Purina Animal Nutrition LLC in Statesville, NC, NCG500622
Question 5: The boiler blowdown intermittently discharges into an exterior settling pond. Due to the
intermittent flow into the pond and evaporation from the pond, the pond rarely reaches the elevation
of the top of the 6-inch diameter pond overflow pipe. On the rare occasion when the pond water
reaches the top of the overflow pipe, the water discharged from the pond flows in underground piping
to the Sampling Combined Stormwater & Permitted Wastewater Outfall 003 where the water discharges
into a ditch and then into an unnamed tributary where it eventually reaches 3 d Creek WS #37.
1) Settling pond surface area = 4,000 sq ft
2) Settling pond volume = 100,000 gal
3) Total system volume (boiler, piping, & pond) = 200,000 gal
4) Settling pond has a 6-inch diameter overflow pipe that carries water from the pond to outfall
003 where the water enters a ditch.
5) The settling pond is the only treatment system utilized for the discharged boiler blowdown
water.

NPDES Compliance and Expedited Permitting

Aquatic Toxicity Branch
Subject: Biocide Use Review
Purina Animal Nutrition, LLC
NPDES # NCG500622
Iredell County
Purina Animal Nutrition, LLC has requested approval of three chemicals: Nalco 1720,
NexGuard 22352, and Tri-ACT 1820. These products will be discharged from its Outfall 003
and into Third Creek.
Calculations predict the use of Nalco 1720, NexGuard 22352, and Tri-ACT 1820 products will
cause toxic impacts to aquatic life in the receiving water body, Third Creek. Therefore, the use
of these products as proposed at Purina Animal Nutrition, LLC is not approved.
We have been in direct contact and corresponded with consultants for Purina over months to
modify this proposal in ways that would allow for approval of these biocides. One option
explored adjusting dosage rates of each chemical. We had consultants explore the possibility of
demonstrating that the usage of the proposed biocides is directly related to water quality
parameters specified in the facility's NPDES Permit that would justify their usage at specified
dosage rates. Another suggestion was to find other chemicals and that would pass the model.
There are other options that Purina could explore. The facility could perform a Chronic multi -
concentration Ceriodaphnia 7-day reproduction test with these products. Purina could also have
a toxicity testing requirement added to its NPDES Permit. Another possibility is that because
discharge flow is historically low and it is doubtful the discharge reaches the stream, Purina
could explore an evaporative type non -discharge system to eliminate the need for a discharge
permit.
Please let us know if you have questions.
