,N=TTEN RECORD:
�Mr. Xluttz called to inform me that his facility today had discon-
tinued use of phosphoric acid for neutralization of the plant's
discharge to the NSCC pretreatment system. He stated that the acid
had been replaced by sulfuric acid, but. there would still he a
continuous. feed of 2.5 gpd of approx. 70$ phosphoric acid to
maintain nutrient levels in the biolagoon (L3).
He also stated that NSCC was currently experimenting with use of
sand filters to as a possible method of improving their discharge
quality.
basked him whether there had been any word from the NCDEM or EPA
on when the sludge in lagoon #2 Gould be disposed of. He said NSCC
had not reneived a decision or instructions from the. state.

INTER -OFFICE MEMO
August 22, 1994
To: Ray Paradowski
From: Brian Owen
Subject: U ilizing Lagoon #4 for Processing of Wastewater
cc: Dr. A. Alam - Bridgewater
B. Algiere
Phil Dearman - City of Salisbury
H. Crmulich - Bridgewater
K. Kluttz
As of 08/19/94, the VJWTP at National Starch, and Chemical in Salisbury is
currently and has been treating wastewater from plant and plume periphery wafer using
La;ocn's 01 and Y3 and decanting from Lagoon 43 through the clarifier to the POTW_
We are currently using a diesel pump with fittings and hoses to decant from Lagoon 3.
These materials and the diesel pump comes to a. monthly rent char?e of approximately
$4,000.00_
Currently, Lagoon #4 is not being used in our system because we are no[ sure if it
will be used to treat any wastewater or sludge from Lagoon R2 as of yet. Suite Lagoon .
#4 has been cleaned and is ready for use, we would like to use Lagoon n4 in the time
being in our system. By introducing Lagoon 94 into our system for treatment. we would
incur the following benefits:
1. If Lagoon 04 could be used, we would not need the diesel pump to decant from
Lagoon n3 to the clarifier. We would use the ITT Self Priming Pumps in place that
would automatically decant water from Lagoon 43 to Lagoon 44 at a nominal rate of
2600 galloas/tninute. Of course, these pumps will be programmed to automatically come
on for 30 minutes during two of the six settling time cycle intervals for the bioreactor
cycle system. This would SAVE NSC approximately S4000.00 per month.
2. We will be able to operate the clarifier the way it was meant to be operated by keeping
a constant level and overflowing the water into the trough then to the POTW. Any solids
that floc out can be collected in the clarifier and any floating material can be raked off.
3. Another benefit would be that the wastewater would receive more aeration by using
Lagoon r4. We would keep Lagoon 44 only one-half of capacity in the case that Lagoon
44 would be needed for any other use (i.e. treatment of wastewater/sludge, from Lagoon
TZ). �,Ve could in effect empty Lagoon 44 in approximately 2 to 3 days if it would be
needed

��addition, the Wastewater Treatment Plant has switched out the Phosphoric
Acid 75% storage tank v,1th a Sulfuric Acid 96% storage tank. As of 08119/9�4. we will
be using Sulfuric Acid 96% for our pH adjustments to our wastewater in Lagoon r1. We
are currently installing a work station in the same area as the Sulfuric Acid 96% storage
tank to add approximately 22.5 to 5 gallons ofPhosphoric Acid 75% to Lagoon #1 per
