Subject: Draft NPDES Permit Renewal
Permit NC0023981
Lower Creek WWTP
Caldwell County
Grade IV Biological WPCS
SIC Code 4952
Dear Ms. Triplett:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains.There are several changes from the existing permit, including the following:
• Based on details provided in the submitted Process Narrative, system components in the
Supplement to Permit Cover Sheet have been revised.
• Because it had expired on August 31, 2019,the compliance schedule for hardness-dependent
metals has been removed from the permit,as well as the Effluent Sheet showing the limits and
monitoring requirements for Total Cadmium and Total Copper under compliance schedule.
• Based on the reasonable potential analysis(RPA)involving submitted Hardness data,the limits
for Total Cadmium have been revised from 1.8 µg/L monthly average and 9.9 µg/L daily
maximum to 1.6 µg/L monthly average and 8.2 µg/L daily maximum [See A.(1.)].
• Based on the RPA involving submitted Hardness data, the limits for Total Copper have been
revised from 25.7 µg/L monthly average and 33.0 µg/L daily maximum to 21.6 µg/L monthly
average and 27.0 µg/L daily maximum [See A.(1.)].
• Based on submitted data not exceeding the compliance level of 10 µg/L per the April 13,2007
Division's Cyanide Compliance guidance memo, Cyanide limits and monitoring have been
removed from the permit[See A. (1.)].
• Based on the RPA showing reasonable potential to violate state water quality standards,Total
Silver and Zinc limits have been added to the permit and the quarterly monitoring requirement
has been changed to monthly monitoring [See A. (1.)].
• The Permittee was offered compliance schedules to help meet proposed new and revised limits
for Cadmium,Copper, Silver and Zinc,but was informed that compliance schedules were not
needed.No new compliance schedules are proposed.
• Based on Mercury TMDL evaluation showing mercury values reported at levels> 1 ng/L and
since the permitted flow is>2 MGD, Special Condition A. (6.) -Mercury Minimization Plan
has been revised toward its maintenance.

• Instream monitoring parameters have been removed from the Effluent sheet [A. (1.)] and
placed as a separate Special Condition [See A. (2.)].
• Some of the wording has changed in Special Condition A. (3.) — Chronic Toxicity Permit
Limit,please review each paragraph carefully.
• Special Condition A. (4.)—Effluent Pollutant Scan has been modified to include the specific
three years in which the Effluent Pollutant Scan shall be performed(2023,2024,and 2025).
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and program reports. The requirement to continue reporting discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR)internet
application has been added to your NPDES permit [See A. (5.)].
• A notation was made concerning the Electronic Reporting Rule—NPDES Electronic Reporting
Rule — Phase 2 Extension. EPA extended the Phase 2 deadline to December 21, 2025. The
current compliance date, effective January 4, 2021, was extended as a final regulation change
published in the November 2, 2020 Federal Register [See A. (5.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[See A. (1.)], Instream Monitoring [See A. (2.)], and Effluent Pollutant Scan [See A. (4.)].
• Regulatory citations have been added to the permit.
The NPDES standard conditions(Parts II,III,and IV)that are a part of the permit are not included
in this draft document (cover, map, and Part I). The conditions are the same as in your current
permit except that agency and division names have been updated.The latest version is available at
https://bit.ly/3k5NFaL and can be viewed online or downloaded as a PDF file.

A.(3.) CHRONIC TOXICITY PERMIT LIMIT(Quarterly) [15A NCAC 02B .0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 44%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the"North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised December 2010,or subsequent versions
or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised December 2010) or
subsequent versions.The tests will be performed during the months of February,May,August and November.
These months signify the first month of each three month toxicity testing quarter assigned to the facility.Effluent
sampling for this testing must be obtained during representative effluent discharge and shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the
permit limit, then multiple-concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure"(Revised-December 2010)or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered electronically using the
Division's eDMR system for the months in which tests were performed,using the parameter code TGP3B for the
pass/fail results and THP3B for the Chronic Value.Additionally,DWR Form AT-3(original)is to be sent to the
following address:

A.(5.) ELECTRONIC REPORTING-DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports(DMRs)and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21,2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
Section B.(11.) Signatory Requirements
Section D.(2.) Reporting
Section D.(6.) Records Retention
Section E.(5.) Monitoring Reports
1. Reporting Requirements (Supersedes Section D.(2.)and Section E.(5.)(a)1
The Permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report(eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. The eDMR system may be
accessed at: https://deq.nc.gov/about/divisions/water-resources/edmr.
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access,then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms(MR 1, 1.1,2,3)or alternative
forms approved by the Director. Duplicate signed copies shall be submitted to the following address:
NC DEQ/Division of Water Resources/ Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
See"How to Request a Waiver from Electronic Reporting"section below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21,2025, the Permittee must electronically report the following compliance
monitoring data and reports,when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports;and
• Clean Water Act(CWA)Section 316(b)Annual Reports.

Permit NC0023981
The Permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting"section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9),the permittee must identify the initial recipient at the time
of each electronic submission.The Permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program)that is the designated entity
for receiving electronic NPDES data[see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at:
https://www.federalregister.gov/doc um ents/2015/10/22/2015-24954/nati onal-pollutant-discharge-
elimination-system-npdes-electron ic-reporting-rule.
Electronic submissions must start by the dates listed in the"Reporting Requirements"section above.
3. How to Request a Waiver from Electronic Reporting
The Permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
