Mr. Nielsen:
The Division of Water Resources(the Division or DWR)hereby issues the attached NPDES
permit update for the subject facility. We issue this pursuant to the requirements of North
Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the U.S. Environmental Protection Agency dated October 15, 2007,or as
subsequently amended.
The Division acknowledges receiving(on September 7, 2021)your request to increase the
existing flow limit for the subject permit on behalf of Solis Brightleaf Apartments (SBA). The
subject dewatering system is supported by regular treatment generating a discharge to Surface
Waters of the State. Considering SBA's reported discharge flow record to date,the Division
hereby grants an increase in permitted flow from 0.0065 to 0.014 MGD.
Please note that we have updated the text in permit Condition A. (4.)ELECTRTONIC
REPORTING.NPDES Standard Conditions (Parts II, III,and IV) are part of this permit,but are
not included in this draft [cover letter,map, and Part I only]. The latest version of Parts II, III,and
IV are available at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.
This permit and authorization to discharge shall expire at midnight on June 30, 2023. If SBA
desires to continue this permit, a renewal application must be submitted no later than January 31,
2023 (180 days prior to permit expiration).

NPDES Permit NC0089702
A. (2.) ACUTE TOXICITY—PASS/FAIL LIMITED (Quarterly)
[NCAC 02B .0500 et seq.]
The permittee shall conduct acute toxicity tests Monthly using protocols defmed in the North Carolina Procedure
Document entitled"Pass/Fail Methodology for Determining Acute Toxicity In A Single Effluent Concentration"
(Revised December 2010 or subsequent versions).Monitoring shall be performed using Fathead Minnow
(Pimephales promelas)24-hour static test.The effluent concentration at which there may be at no time significant
acute mortality is 90%(defmed as"treatment two"in the procedure document). Effluent sampling for this testing
must be obtained during a representative effluent discharge. Sampling shall be performed at the NPDES-permitted
final effluent discharge below all treatment processes.
Should any single monthly monitoring indicate a failure to meet specified limits,the Permittee shall immediately
contact the Aquatic Toxicology Branch,attention Hannah Headrick;and monitoring shall begin on each
subsequent discharge until a single test is passed.Upon passing,this test requirement shall revert again to
Monthly monitoring.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form(MR-1)for the month in which it was performed,using the parameter code TGE6C.
Additionally,DWR Form AT-2(original)is to be sent to the following address:
Attention:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after
the end of the reporting period for which the report is made.Test data shall be complete and accurate and include
all supporting chemical/physical measurements performed in association with the toxicity tests,as well as all
dose/response data.Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity(AT)test form indicating the
facility name,permit number,pipe number,county,and the month/year of the report with the notation of"No
Flow"in the comment area of the form.The report shall be submitted to the Water Sciences Section at the address
cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,then monthly
monitoring will begin immediately until such time that a single test is passed.Upon passing,this monthly test
requirement will revert to quarterly in the months specified above.Assessment of toxicity compliance is based on
the toxicity testing quarter,which is the three-month time interval that begins on the first day of the month in
which toxicity testing is required by this permit and continues until the final day of the third month.
Should any test data from either these monitoring requirements or tests performed by the North Carolina Division
of Water Resources indicate potential impacts to the receiving stream,this permit may be re-opened and modified
to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document,such as minimum control organism
survival and appropriate environmental controls,shall constitute an invalid test and will require immediate
follow-up testing to be completed no later than the last day of the month following the month of the initial
monitoring.

A. (4.) 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)l
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.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
reported via the eDMR system no later than the last calendar day of the month following the
completed reporting period. 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.

NPDES Permit NC0089702
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.
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/documents/2015/10/22/2015-
24954/national-pollutant-di scharge-elimination-system-npdes-electronic-reporting-rul e
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
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time,monitoring data
and reports shall be submitted electronically to the Division unless the permittee re-applies for and is
granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting
waivers are not transferrable. Only permittees with an approved reporting waiver request may
submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
