32. Are there any local issues affecting the pretreatment program (e.g.. odor, plant closing, new or proposed plants)?
® Yes ❑ No If yes, Explain. The POTW's only SIU (Auria Albemarle, LLC) ceased the dyeing operation and SIU's flows
have been significantly been reduced.

Permitting (Industrial Waste Survey-IWS):
38. How does the POTW become aware of new or changed Users? City's Economic Development staff would contact
Public Utilities Director and/or Pretreatment Coordinator.
39. Once the POTW becomes aware of new or changed Users, how does the POTW determine which industries have the
reasonable potential to adversely impact the WWTP and therefore require a new permit or a permit revision? (Who is an
SIU?) The Pretreatment Coordinator would evaluate the information on the IWS form (Short/Long Forms),
discharge characteristics including flow volumes, NPDES POCs, SIC Codes/categorical determinations, and
potential impacts to the WWTP.
40. Does the POTW receive waste from any groundwater remediation projects (petroleum, CERCLA) or landfill leachate?
®Yes ❑No If Yes, How many are there? 1
Please list each site and how it is permitted, if applicable. POTW's landfill leachate; local permit.
41. Does the POTW accept waste by (mark if applicable) ® Truck ®Dedicated Pipe ❑ NA
42. If the POTW accepts trucked waste, what controls are placed on this waste? (example. designated point, samples drawn,
manifests required) The WWTP has a designated point at the WWTP for the septage haulers and unloading
activities only occur during first shift (7 am — 3 pm). The septage haulers pre -pay for tickets (includes contact
information) that are turned in at the WWTP following unloading activities. Manifests are maintained along with
random sampling.
43. How does the POTW allocate its loading to industries? Mark all that apply
❑ Uniform Limits ® Historical Industry Need ❑ By Surcharge ❑ Categorical Limits ❑ Other
Explain Other:
44. Review POTW's copies of current allocation tables for each WWTP. Are there any over allocations? ❑ Yes ® No
If yes, What parameters are over allocated?
45. If yes to #44, What is being done to address the over allocations? (short-term IUPs, HWA to be revised, pollutant study, etc.)
46. Does the POTW keep pollutant loading in reserve for future growth / safety? ® Yes ❑ No
If yes, what percentage of each parameter? 10%
47. Has the POTW experienced any difficulty in allocation? (for example: adjudication by an industry) ❑ Yes ® No
NC DWR Pretreatment Audit Form Revised: December 2016 Page 3

48. How does the POTW decide on which pollutants to limit in the permits? Monitor for? (for example: were only those pollutants
listed on the application limited; categorical parameters; NPDES Pollutants of Concern) NPDES POCs, categorical parameters,
potential impacts to WWTP and industry need.
49. How does the POTW decide what the monitoring frequency should be for the various pollutants in industry permits ? Explain.
New SIUs would be required to perform monthly monitoring for twelve months to determine baseline. A reduction of
the monitoring frequency would be based on sampling results. Monitoring also based on categorical determinations and
potential impacts to WWTP. Twice per year monitoring would be performed at a minimum.
Permit Compliance:
50. Does the POTW currently have or during the past year had any permits under adjudication? ❑ Yes ® No
If yes, which industries? What was (will be) the outcome of the adjudication?
51. Demonstrate how the POTW judges compliance. This should include compliance judgment on all violations of limits, reporting
requirements, and permit conditions, as well as for SNC. SNC determinations based on Compliance Judgment Worksheet.
Violations (limit, monitoring, permit condition, etc.) based on Division -approved ERP.
52. Does the POTW use the Division's model inspection form or equivalent? ® Yes ❑ No
If no, does the POTW form include all DWQ data? ❑ Yes ❑ No
53. Were all SIUs evaluated for the need of a slug/spill control plan during their most recent inspections? ® Yes ❑ No
If no, Explain.
54. What criteria are used to determine if a slug/spill control plan is needed? The only SIU is required to have slug/spill control
plan. New SIUs would be evaluated for floor drains, secondary containment, chemical storage areas, and/or potential
impacts to WWTP.
55. What criteria does the POTW use to determine if a submitted slug/spill control plan is adequate? Checklist used during
inspections, contact information kept current, presence of spill response equipment, adequacy of secondary containment
and chemical storage practices.
56. How does the POTW decide where the sample point for an SIU should be located? Categorical — two sampling points with one
being the categorical effluent and second being all combined waste streams; Non -categorical — all combined waste streams.
57. Has the POTW established a procedure to ensure that representative samples will be taken by the POTW or SIU each time?
(example: correct location; proper programming of sampler; clean equipment; swirling the sample bucket uniformly)
POTW: ® Yes ❑ No SIU: ❑ Yes ❑ No If yes, Explain. POTW maintains sampling SOPS and sampler
manuals. Note: POTW staff collects all samples.
58. Who performs sample analysis for the POTW for Metals — Environment 1
Conventional Parameters - Environment 1
Organics — Environment 1
59. Explain the Chain of Custody Procedure used for both in house and commercial lab samples.
City staff uses internal COC (flow, pH, and temperature) and contracted laboratory (Environment 1) COCs.

FILE REVIEW COMMENTS:
8. The POTW reported effluent limit violations in September 2019 (TSS and fecal coliform), June 2019 (BOD, ammonia, fecal
coliform, chronic toxicity), May 2019 (BOD, ammonia, fecal coliform), April 2019 (BOD, ammonia, TSS), March 2019 (TSS and
ammonia), February 2019 (TSS and ammonia), January 2019 (BOD, ammonia, TSS), December 2018 (ammonia) and November
2018 (ammonia and fecal coliform). The WWTP issues attributed to these violations include the following: low influent BOD
loading, inability to isolate individual aeration basins during low flow/organic loading conditions and excessive I&I.
9. The POTW has submitted an application to the Division for an SOC to address both the collection system and WWTP. The SOC is
currently under Division review.
21. The POTW will need to submit a copy of the IJA (with Stanly County) to the Division's Pretreatment Unit.
72. The POTW last inspected Auria Albemarle, LLC on 12/13/18.
78. The POTW collects all samples for the SIU.

Auria Albemarle, LLC (Auria) currently performs carpet tufting and latex backing. The dyeing process ceased in September 2018 and
caused a significant reduction of the flows to the POTW by approximately 90%. The facility has approximately 188 employees and
operates two production shifts, sixteen hours per day five to six days per week. Auria currently produces one million yards of product
per month. The facility's pretreatment system currently includes dual lint screens and continuous flow measurement. US Ecology (or a
subcontracted company) has been contracted to dispose of the facility's universal waste, carpet waste, etc. Safety Kleen disposes of any
used motor oil and Republic Services disposes the screenings (lint screening system).
SUMMARY AND COMMENTS:
The POTW's LTMP was recently revised and approved by the Division in April 2019. The June 2019 LTMP sampling event revealed
the detection levels of several parameters [Bis (2-ethylheyxl) Phthlate, Cr6, Ag, As, Cd, Pb, Se] being above the LTMP's detection
levels. The POTW had changed contracted labs prior to the September 2019 LTMP sampling event with only As and Se detection
levels being above the LTMP's detection levels. The Pretreatment Coordinator will contact the contracted lab to address these
detection levels.
The records reviewed during the inspection were organized and well maintained. The POTW's Industrial Pretreatment Program was
being properly implemented.
