HISTORY
WestPoint Stevens used to operate a major textile facility in Wagram, Scotland County. The company
made terry towels and dyeing of synthetic fibers for carpet manufacture. The 7.0 MGD wastewater
treatment facility was used for the treatment of wastewater from carpet dyeing,textile manufacturing,and
domestic waste. WestPoint Stevens went bankrupt, and the textile operation was bought by WestPoint
Home;the name change was in 2004. By 2007 WestPoint Home had ceased to manufacture textiles at the
Wagram site. A carpet business owned by Gulistan continued to manufacture carpets after 2007
discharging their industrial wastewaters to the WestPoint WWTP. WestPoint Home used the facility as a
distribution center and continued to operate the wastewater treatment facility to treat waste from domestic
and carpet dyeing operations.All industrial operations ceased in early 2013.Warehousing and
distribution operations ceased in October 2013.
In 2017 the facility has been sold to Scotland County and will be converted for municipal use.The
Division developed a water quality model to develop new permit limits for municipal facility,the model
was competed in 2023.The permit contains a special condition that requires a new owner to submit a
request for Major Modification,Engineering Alternative Analysis,and EPA form 2A before they can
commence discharge of the municipal wastewater.Therefore,this permit will serve as the basis for a
future municipal permit.
FACILITY STATUS
The facility is no longer operating the wastewater treatment plant.The treatment plant has not discharged
any effluent since 2014.
RECEVING STREAM
This facility discharges es to the Lumber River, subbasin 03-07-51,HUC 0304020303,in the Lumber River
Basin.The stream is classified HQW WS-IV B-Sw.This section of the Lumber River is not listed on the
2022 NC 303(d)list.

COMPLIANCE REVIEW
Reasonable Potential Analysis(RPA)
A reasonable potential analysis(RPA)was not performed since the facility did not discharge since 2014.
Compliance
The last compliance evaluation inspection was conducted on January 25,2023. The report did not have
any significant issues or findings.The ORC visits the facility periodically and pumps and aerators are
occasionally exercised to maintain their functionality.
Toxicity Testing
Current requirement: Chronic P/F @ 1.6%,based on 1.2 MGD flow.Chronic P/F @ 9%,based on 7
MGD flow. The facility has been in compliance with its toxicity limit since its last renewal in 2005.
Proposed requirement: Chronic P/F @ 5.8 %,based on 1.2 MGD flow. This increase from 1.6%is based
on the requirements of 15A NCAC 2B .0224(G)for HQW and new USGS flow data.
Instream Monitoring
When the facility was producing textiles,it collected instream data for temperature,dissolved oxygen,
color and conductivity. Collected data showed very little variability in upstream and downstream samples
and no impact from the facility.
PERMITTING STRATEGY
Existing limits for BOD,COD,TSS, Sulfide,Total Phenols, and Total Chromium are based on effluent
guidelines for Carpet Finishing.The proposed limits are based on the modeling conducted for the future
municipal discharge since this facility no longer produces textiles and will be operating as a domestic
WWTP in the future.

SUMMARY OF PROPOSED CHANGES
1. The flow tier for 7 MGD was eliminated since the new owner(Scotland County)did not request
speculative limits for the higher tier.
2. Limits and monitoring for Sulfides,Total Chromium,Total Phenols,Color,and COD were
removed from the permit since the facility discontinued all manufacturing operations.
3. Monitoring for Total Manganese and Total Iron was eliminated since the water treatment plant
ceased operation.
4. Limits for BOD5 and NH3-N were changed based on the modeling for a future municipal facility.
5. Limits for TSS were changed based on the new classification of the facility.
6. The Chronic Toxicity limit was changed from 1.6%to 5.8%based on the requirements for HQW
waters(15A NCAC 2B .0224(G))and new USGS flow data.
7. Additional Monitoring Requirements for Permit Renewal Special Condition was added to the
permit to satisfy the Division's requirements for Major Municipal Permits.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE
