SUBJECT: NPDES Permit Application for Unifi Spun Yarns, Inc.
Mount Pleasant, North Carolina.
Dear Sir:
Unifi recently merged with Vintage Yarns obtaining the
cotton spinning manufacturing site at Mount Pleasant. Since
completion of the merger, I became aware of the nonpermitted
discharge of cooling tower blowdown and air washer overflow
wastewater. This wastewater discharges directly to an
unnamed tributary of Adams Creek. Please recognize that
Unifi is correcting this situation as quickly as possible.
The water treatment program was formerly under the
direction of Betz Entec. Upon completion of Biocide
Worksheets (Form 101) it became apparent that the treatment
program was unacceptable. Nalco Chemical Company has been
hired to take over the water treatment program and they have
provided the treatment program described in the attachments.
Please find enclosed, three copies of a completed Notice
of Intent, NPDES permit application with completed biocide
worksheets for Unifi Spun Yarns, Inc. (a subsidiary of Unifi,
Inc.), Mount Pleasant. Also enclosed is a check for the
permit application fee.
Unifi is investigating piping all industrial wastewater
into the Mount Pleasant sewer system.
Sincere
C. Timoth Cole

Dear Mr. Cole:
The Division of Environmental Management has received your correspondence
dated December 2, 1993 requesting that we cancel your application for the subject permit
application. We also have confirmation from our Mooresville Regional Office that the
subject facility no longer discharges to the surface waters of the state. Therefore, we are
cancelling your application and returning your application materials. Enclosed please find
the application materials submitted for renewal. Application fees are non-refundable
according to North Carolina Administrative Code 15A NCAC 2H .0105 (b)(1).
If in the future, you determine that you wish to operate a wastewater discharge
system, you must first apply for and receive a new NPDES Permit. Discharging
wastewater without a valid NPDES Permit will subject the discharger to a civil penalty of
up to $10,000 per day. If you have questions regarding this matter, please contact Susan
Robson at [phone].

On October 6, 1993 we received a biocide review request submitted by Unif. Spun Yarns, Inc.
for the use of Nalco 7320 in their air washers and cooling towers 1-4. Data submitted by the subject
facility concerning the dosage rate of the compound, system volumes, average daily discharges, toxicity
of the active ingredient and/or breakdown product, and minimum stream flow were reviewed and
evaluated. In reviewing the submitted materials, discrepancies were noted regarding the correct dosage
rate. On October 10, 1993 I spoke with Mr. David Anthony of Nalco Chemical Company to clarify
these concerns. He informed me that he would the dosage rates and resubmit corrected forms to our
office.
On December 7 and 8, 1993, after no information was received, I contacted Mr. Timothy Cole,
Environmental Affairs Manager at Unify Spun Yarns, Inc. He stated that all discharge is now being
discharged into the Mt. Pleasant sanitary sewer system which is treated by the Water and Sewer
Authority of Cabarrus County and requested that the biocide request be withdrawn. This was confirmed
by your fax to me of a 12/2/93 memo from Mr. Cole to Coleen Sullins (attached) and by Mr. Kim
Colson at the Mooresville Regional Office (phone conversation 12/14/93). Since the facility no longer
plans a direct discharge, there is no need for the biocide approval process to be completed by this office.
If there are questions regarding this review please contact me at [phone].

Attention: Mr. Tim Cole, Environmental Affairs Manager
Dear Mr. Cole:
This letter is to serve as an attachment to the Worksheet 101 regarding the Mount Pleasant
facility. The purpose of this letter is to explain the method of application of Nalco 7320 which
will allow for non -toxic discharge.
Nalco 7320 is to be applied to the cooling 6.
towers and air washer system. Prior to application,
the blowdown from the cooling towers and air washer system will be locked out for a period of GF3z " z
no less than four (4) hours. Due to the very short half-life of this biocide, this period will allow
the biocide to degrade so that it is non -toxic.
If you have any questions, please do not hesitate to contact me through our Charlotte district
office at [phone].
Sincerely,
G�

Average Daily Discharge - This value is expressed in million gallons per day and
should represent the total monthly volume divided by the 4 of days
discharged. The date should reflect the highest average daily discharge
over any three consecutive months.
Ins (team Was le Conconlration - The I.W.C. is dofined -as the percont waste In the
receiving stream during low flow (7010) conditions.
7010 - This value is expressed in cubic feel per second and represents the lowest
average :low in the receiving stream over a seven day period which re -occurs
every ter: years. It is this low flow value by which all toxic substances
are evaluated as to their inslrcam impacts according to state regulations.
Dosage Rate - The dosage rate is to be considered as the maximum daily quantity
in grams per day of the whole treatment product.
Half Life The. half Iife-of,.a.produc.l is .the Iength.of time, in days, that the
product will require to degrade':l0 non =toxic"components. These.hatves
vary considerably with pH and!%'temperature. Il is to the advantage of the
discharger to obtain this information since it allows less restrictive
discharge quantities.
LCso'- An LC6o value is the concent.ralion of the whole product which causes Acat h

ReguIated.Limitation - This is the maximum inslream concentration of product
which is allowed by water quaIily regulation to exist in natural 5 u r ( 8 c e
