WestPoint Pepperell
APPAREL FABRICS DIVISION

Health and Natural Resources
Division of Environmental Management
P.O. Box 29535
Raleigh, North Carolina 27626-0535
Dear Ms. Sullins
Attached you will find an application for renewal of NPDES permit
No. NC0004618 issued 9/1/93 to WestPoint Pepperell, Inc. (Lumberton
Plant). The scheduled expiration date is 11/30/94.
The existing permit identifies two outfalls; 001 (wastewater to
Lumber River) and 002 (filter backwash to Jacobs Swamp). Prior to
expiration of this permit we will have the filter backwash routed
into the wastewater treatment plant and will therefore eliminate
outfall 002.
Our current permit requires monitoring three times per week for
chromium, phenol, and sulfide. These analyses must be run in a
contract laboratory and represent considerable expense ($12,667.20
per year). Given the fact that we are an industrial discharger
having absolute control over what goes into the treatment plant,
and the enormous historical data base showing good consistency, it
seems reasonable to ask that the testing frequency for these
parameters be reduced to once per week. We do not see any tangible
benefit from the current test schedule.
You should also note that our company name has changed to Alamac
Knit Fabrics, Inc., a wholly owned subsidiary of WestPoint Stevens,
Inc. Accordingly, we submitted a request for name change on
11/8/93 and included a check for $100.00 to cover the change. As
of this date we have not received notice of the name change and the
check is still outstanding. Given the time which has elapsed and
the attached application, it seems meaningless to pursue the
November request. Therefore we ask that you return the $100.00
check and incorporate the name change as part of the new permit.
POST OFFICE BOX 1347, LUMBERTON, NORTH CAROLINA 28359 • AREA 919 739-2811

4 ` p—Facility has requested in the renewal of pipe 001 to include the discharge from pipe 002.
? All limits except toxicity testing requirement will remain the same as existing for pipe 001 with the
addition of limits from pipe 002.
New toxicity testing limit due to -slight change in 7Q10 from the low flow profile report on the
Lumber River. Lumberton WWT�and"Alpha Cellu ose_ will be using the same 7Q10 from the low
flow report.

CHRONIC TOXICITY PASSMAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is L-I_'Yo (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
quart monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed after thirty days from the effective date of this permit during the months of
mav1 Ulm, 6eo, 11p (-_ Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DEM Form AT -I (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the Notch Carolina Division of
Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

PART IV - EVALUATION AND RECOMMENDATION
It is the recommendation of the Fayetteville Regional Office that
subject NPDES Permit No. NC0004618 be reissued. Also, it should be noted that
all wastewater associated with discharge point 002 will be rerouted to the
polishing pond and discharged via discharge point 001.
It was noted in the cover letter of Alamac Knit Fabrics, Inc. permit
application, that the facility requested that monitoring for chromium, phenols
and sulfide be reduced from three (3) time per week to once (1) per week.
The Fayetteville Regional Office has no objections to this request, since
sufficent data has been collected from this facility in the past that confirms
that this facility has no problem maintaining permit limit compliance with
these parameters.

2. Seplic Tank/Sand Filter Systems consisting only of seplic tanks, dosing apparatus, pumps,sand fillers, disinfection
and direct discharge;
3. Lagoon Systems consisting only of preliminary treatment, lagoons, pumps, disinfection, necessary chemical treatment for
algae or nutrient control, and direct discharge;
4. Closed -loop Recycle Systems;
5. Groundwaler Remediation Systems consisting only of oiVwaler separators, pumps, air -stripping, carbon adsorption, disinfection
and dispos.J;
6. Aquaculture operations with discharge to surface waters;
7. Wa!er Plant sludge handling and back -wash water treatment;
8. Seafood processing consisting of screening and disposal.
9. Single-family discharging systems, with the exception of Aerobic Treatment Units, will be classilied if permitted after July 1,
