By copy of this letter, I am requesting confirmation from our Mooresville Regional Office that the
facility never was constructed. Upon verification by the regional office that the facility was never
constructed and that the permit is no longer needed, the civil penalty will be rescinded and the permit will
be rescinded. The revocation of the permit for non-payment of the 1993 Annual Administunng Permit
Fee will also be deleted from our computer system.
If there is a need for any additional information or clarification, please do not hesitate to contact

SUBJECT: REVIEW OF INDUSTRIAL DISCHARGE APPLICATION FOR UN'I i
-SPUN YARNS, INC., MT. PLEASANT, N.C.
•
Dear Mr. Cole:
•
• The Water &Sewer Authority has reviewed the industrial discharge application submitted
for Unifi Spun Yarns, Inc. in Mt. Pleasant. At this_time, the Authority will not issue a permit
to the facility since (1) the volume of process wastewater generated is less than 25,000 gallons
per day; and (2) the facility is not subject to any federal categorical limitations.
The Authority hereby grants permission to Unifi Spun Yarns to continue their discharge
of boiler and non-contact cooling water into the sanitary sewer system, however, all of the waste
oil and solvents shall not be disposed of through the sanitary or storm sewer systems.
The Authority will conduct random sampling at Unifi Spun Yarns to determine the
constituents or pollutants present in the wastewater discharge. If random sampling show levels
of pollutants in exceedance of the Sewer Use Ordinance limitations and/or the volume of process
wastewater increases to 25,000 gallons or more a day, the Authority will be required by State
and local regulations to issue a permit.
•
Please notify the Authority prior to any process changes or expansions at the facility.
Failure to obtain approval or a permit from the Authority prior to any modification may subject
Unifi Spun Yams to an enforcement action by the Authority in accordance with Federal, State
and.local regulations. •

SUBJECT: NPDES Permit Application for Unifi Spun Yarns, Inc.
Mount Pleasant, North Carolina.
1)
Dear sir:
Unifi recently merged with Vintage Yarns obtaining the 7 M
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

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 6P14
