SUBJECT: Pretreatment Audit Inspection (PAI)
City of Mount Airy
NPDES# NC0021121
Surry County
Dear Mr. Marion:
On August 11, 2022 a Pretreatment Audit Inspection (PAI) was performed by Jim Gonsiewski of
the Winston-Salem Regional Office. Mr. Chris Marion was present for the inspection. The purpose
of this inspection was to determine the effectiveness of the City's pretreatment program, which
included a detailed file review, review of the POTW performance, planning, sampling, and
compliance judgement program, and adherence to the enforcement response plan (ERP).
Additionally, an inspection of the Texwipe facility was conducted in conjunction with an
inspection by the City of Mount Airy.
Background
This is a 7 MGD permitted facility. The City has one (1) Significant Industrial User (SIU)
(Texwipe) which is non -categorical. This facility entered the pretreatment program in July 2022.
A former SIU, Professional Rental Services, rescinded their permit in May 2022.
POTW Interview
There are no plant problems related to pretreatment issues and no NPDES permit limit or
monitoring violations were recorded from January 2021 through July 2022. The facility is very
well operated.
Pretreatment Program Elements Review
The Headworks Analysis (HWA) renewal was submitted on April 23, 2021. This HWA is
currently under review.

The Sewer Use Ordinance (SUO) was approved on October 25, 2012.
The Enforcement Response Plan (ERP) was approved on February 5, 2020.
The Long -Term Monitoring Plan (LTMP) was approved on December 15, 2021.
LTMP File Review
The Long -Term Monitoring Plan (LTMP) is being conducted at the proper locations and
frequencies.
Industrial User Permit (IUP) File Review
A review of the file for Texwipe (#0001) revealed that the monitoring data was well organized and
compliant.
The slug control plan for Texwipe (#0001) is currently being developed by the SIU.
Action Items
No other action items were noted.
The pretreatment program is considered satisfactory. Mr. Marion runs an excellent pretreatment
program. If you have any questions please contact Jim Gonsiewski or me at (336) 776-9800.

Industrial Inspection Comments:
Met with Carl Whitaker, Facility Engineer/Maintenance Manager at 10:10 AM 8/11/2022. Facility is Located at 645 West Pine
Street in Mt. Airy and was constructed in 1995. Previously occupied by Hanes Brands which fabricated cloth wipes until
December 2019. Purchased by Texwipe in 2020. Facility is operational with machines fabricating cloth wipes. The facility is
230,000 square feet. 55 individuals work at the facility in three 8-hour shifts 5 days a week. One clean room is located at the
facility for packaging sterile medical wipes. The facility is expanding to the second floor where Hanes Brands previously operated
their cloth wipe manufacturing. After the cloth is fabricated, washed (a 6-hour wash cycle), and dried, it is placed on rolls for
shipment. The facility is permitted for 200,000 gallons per day of de -ionized wash water which is sent to the POTW. Current
flow is approximately 120,000 gpd. Discharge began in January 2022. The POTW conducted a SIU determination inspection
in May 2022. The permit was dated July 1, 2022.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On August 11, 2022 a Pretreatment Audit Inspection (PAI) was performed by Jim Gonsiewski of the
Winston-Salem Regional Office. Mr. Chris Marion was present for the inspection. The purpose of this
inspection was to determine the effectiveness of the City's pretreatment program, which included a
detailed file review, review of the POTW performance, planning, sampling, and compliance judgement
program, and adherence to the enforcement response plan (ERP). Additionally, an inspection of the
Texwipe facility was conducted in conjunction with an inspection by the City of Mount Airy.
Background
This is a 7 MGD permitted facility. The City has one (1) Significant Industrial User (SIU) (Texwipe)
which is non -categorical. This facility entered the pretreatment program in July 2022. A former SIU,
Professional Rental Services, rescinded their permit in May 2022
POTW Interview
There are no plant problems related to pretreatment issues and no NPDES permit limit or monitoring
violations were recorded from January 2021 through July 2022. The facility is very well operated.
Action Items
No action items were noted.
