2023 PAR Narrative
General Information:
I. The Pretreatment Program Information Database sheet (Enclosure 1) for Rocky River
Regional WWTP is enclosed with corrections marked. The corrections include: (1) # of
WWTP SIUs changed to 15; (2) # of SIUs in Program changed to 16; (3) # of CIUs
changed to 3; and (4) Date of last audit changed to 9/14/2023. The Pretreatment Program
Information Database sheet (Enclosure 2) for Muddy Creek WWTP is enclosed with
corrections marked. The corrections include: (5)# of SIUs in Program changed to 16; and
(6) Date of last audit changed to 9/14/2023. WSACC currently has 15 SIUs at the Rocky
River Regional WWTP and 16 total SIUs in the program.
II. NCDEQ conducted a pretreatment audit inspection of WSACC's pretreatment program
on September 14, 2023 and the program was found satisfactory (Enclosure 3).
III. The PAR for 2022 was approved by NCDEQ on May 5, 2023 (Enclosure 4).
IV. WSACC submitted the Headworks Analysis for RRRWWTP on May 31, 2022. WSACC
is still awaiting approval from NCDEQ.
V. WSACC submitted the Headworks Analysis for MCWWTP on April 28, 2020. WSACC
is still awaiting approval from NCDEQ.
VI. WSACC submitted LTMP amendments on June 30, 2022, with the NCDEQ
acknowledging receipt on July 11, 2022. WSACC is awaiting approval of the LTMP
changes.
VII. WSACC successfully maintained its ISO 14001 certification for the Environmental
Management System for 2023.
VIII. WSACC successfully maintained its ISO 45001 certification for the Occupational Health
and Safety Program for 2023.
IX. WSACC successfully completed recertification of its Public Sector Star Program in 2023.
X. WSACC issues pounds per day limits to the significant industrial users (SIUs). Although
a flow limit is also issued, WSACC does not judge significant noncompliance (SNC) for
this parameter. A notice of noncompliance was sent for flow exceedances. As outlined in
the Comprehensive Guide, Chapter 7, Section E, page 2, flow limits are not required
where all IUP limits are mass based and that the POTW may institute its own policy
relative to flow limit compliance. Also, the definition of "pollutant" in 15A NCAC
211.0903 (25) does not include flow as a characteristic of wastewater.

2023 PAR Narrative
SIU Information:
During the January through June 2023 reporting period:
A. No SNC for this period.
B. WSACC submitted electronically an IUP amendment and Streamlined IUP Submittal
Form on April 27, 2023 for Americhem, IUP#1028. A copy of the approval letter dated
May 8, 2023 from the Municipal Unit of DWR is enclosed (Enclosure 5).
C. WSACC submitted electronically an IUP renewal and Streamlined IUP Submittal Form,
including IUP rationale and allocation table, on May 8, 2023 for Heritage-Crystal Clean
IUP#1030 and amendment on June 16, 2023. A copy of the approval letter dated July 7,
2023 from the Municipal Unit of DWR is enclosed(Enclosure 6).
D. Americhem, Charlotte Water, City of Concord-Hillgrove Water Treatment Plant,
Heritage-Crystal Clean, Intertape Polymer, Owens Corning, Perdue Farms and Star
America did not have any violations of their industrial user pretreatment permits during
the reporting period.
During the July through December 2023 reporting period:
E. CMS Landfill V, IUP#1024, was in SNC for monthly average limits for BOD (Chronic
and TRC) and ammonia (Chronic). WSACC issued a NOV with a fine and has been
meeting with the industry monthly to discuss ways to return to compliance. In addition,
WSACC has issued an Authorization to Construct to the facility on some treatment
improvements to reduce ammonia loadings.
F. Owens Corning., IUP#1041, was in SNC for TRC violations of the monthly average limit
for copper. WSACC issued a NOV with a fine. The facility has cleaned the sedimentation
pit to reduce violations.
G. With the permit renewal for HCC, WSACC changed all the pollutant limits to pounds per
day (lbs./day). The industrial data summary form (IDSF) is submitted separately for each
six-month period,January—June 2023 and July—December 2023.
H. HCC submitted the fourth quarter self-monitoring in November 2023. However, for
many of the pollutants, the laboratory used a high dilution factor due to matrix
interference. WSACC required HCC to resample in December and the lab stated they had
the same problem. WSACC was unable to determine compliance from these samples.
WSACC has requested HCC to resample and split samples among two labs in January
2024 to satisfy the fourth quarter requirement. Therefore, the IDSF will be missing the
fourth quarter self-monitoring. Likewise, the IDSF for January — June 2024 will have
additional samples.

Dear Ms. Metcalf:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit

was received by the Division on April 27',2023.
IUP# 5IU NAME

The review indicates that the IUP is adequate and meets the minimum requirements of 15A NCAC 2H .0916 and
40 CFR 403.8(f)(1)(iii).The allocation table,maintained in the Division's database,has been updated accordingly.
Within 180 days of the effective date of any reissued or modified NPDES permit the permittee would be required
to submit to the Division a written technical evaluation of the need to revise local limits(i.e.,an updated IWS,or
documentation of why one is not needed). This action may include revising, updating, or adding to the list of
Significant Industrial Users(SIUs).Pursuant to 15A NCAC 2H.0907(b)either the Division or the permittee may
initiate pretreatment program revisions.
Federal and State pretreatment regulations require the local delegated pretreatment program to effectively control
and document the discharge of wastewater from Significant/Categorical Industrial Users to the POTW. It is the
POTW's responsibility to ensure that these objectives are consistently met.

to submit to the Division a written technical evaluation of the need to revise local limits (i.e., an updated IWS, or
documentation of why one is not needed). This action may include revising, updating, or adding to the list of
Significant Industrial Users(SIUs). Pursuant to 15A NCAC 2H .0907(b)either the Division or the permittee may
initiate pretreatment program revisions.
Federal and State pretreatment regulations require the local delegated pretreatment program to effectively control
and document the discharge of wastewater from Significant/Categorical Industrial Users to the POTW. It is the
POTW's responsibility to ensure that these objectives are consistently met.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or comments,

Dear Beverly Metcalf:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit(IUP)
renewal submitted by the City of Clinton (NC0020117) for the following Significant Industrial User (SIU). The
submission was received by the Division on 11/02/2023.
SIU# SIU NAME
1010 Atrium Health Cabarrus
The review indicates that the IUP is adequate and meeting the minimum requirements of 15A NCAC 2H .0916
and 40 CFR 403.8 (f)(1)(iii). The allocation table, maintained in the Division's database, has been updated
accordingly.
Within 180 days of the effective date of any reissued or modified NPDES permit the permittee would be required
to submit to the Division a written technical evaluation of the need to revise local limits(i.e.,an updated IWS, or
documentation of why one is not needed). This action may include revising, updating, or adding to the list of
Significant Industrial Users(SIUs). Pursuant to 15A NCAC 2H .0907(b) either the Division or the permittee may
initiate pretreatment program revisions.
Federal and State pretreatment regulations require the local delegated pretreatment program to effectively control
and document the discharge of wastewater from Significant/Categorical Industrial Users to the POTW. It is the
POTW's responsibility to ensure that these objectives are consistently met.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or comments,
