Subject: Draft NPDES Permit Renewal
Permit NC0036277
McDowell Creek WWTP
Mecklenburg County
Grade IV Biological WPCS
SIC Code 4952
Dear Ms. Jarrell:
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 the reasonable potential analysis(RPA) showing no reasonable potential to
violate state water quality standards, the monitoring requirements for Copper and Zinc
have been removed from the permit [See A. (1)].
• Based on the Mercury TMDL evaluation, no Mercury Minimization Plan (MMP) is
required during this permit cycle. Therefore, the MMP Special Condition was removed
from the permit.
• The facility reported Cadmium and Thallium at less than detection, with detection
levels< 1.0 µg/L, and< 5.0 µg/L respectively. The facility's allowable discharge
concentrations are 1.8 µg/L and 2.2 µg/L for Cadmium and Thallium,respectively.
DWR's laboratory identifies the target Practical Quantification Limits(PQLs)
for Cadmium as 0.5 µg/L and Thallium as 2.0 µg/L. 15A NCAC 2B .0505 (e) (4)requires
that all test procedures must produce detection and reporting levels that are below the
permit discharge requirements and all data generated must be reported to the approved
detection level or lower reporting level of the procedure. If no approved methods are
determined capable of achieving detection and reporting levels below permit discharge
requirements, then the approved method with the lowest detection and reporting level
must be used. The facility should use sufficiently sensitive test methods for all pollutants,
including when performing Effluent Pollutant Scans. No limit or monitoring requirement
will be added to the permit at this time. However, failure to analyze to the approved
detection level or lower reporting level may result in a limit for Cadmium and Thallium
during the next renewal.

• Some of the wording has changed in Special Condition A. (2), Chronic Toxicity Permit
Limit. Please review each paragraph carefully.
• Special Condition A. (3)has been modified to include the specific three years in which
the Effluent Pollutant Scan shall be performed(2020, 2021, 2022). In addition, at the end
of the Special Condition, 2nd Species Toxicity Testing Requirements for municipal
permit renewals per Federal Regulations [40 CFR 122.21 (j)(5)] have been added.
• 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 Special Condition
A. (4)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[See A. (1)]
• 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/2BZ4xxx and can be viewed online or downloaded as a PDF file.

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal facilities
that are subject to the Effluent Pollutant Scan requirements listed above are also subject to additional toxicity
testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5). The US EPA requires four(4)toxicity
tests for a test organism other than the test species currently required in this permit. The multiple species tests
should be conducted either quarterly for a 12-month period prior to submittal of the permit renewal application,or
four tests performed at least annually in the four and one half year period prior to the application. These tests shall
be performed for acute or chronic toxicity,whichever is specified in this permit. The multiple species toxicity test
results shall be filed with the Aquatic Toxicology Branch at the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the additional
toxicity tests and reporting requirements. Results should also be summarized in Part E(Toxicity Testing Data)of
EPA Municipal Application Form 2A,when submitting the permit renewal application to the NPDES Permitting
Unit.
A. (4) ELECTRONIC REPORTING OF 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

Raleigh,North Carolina 27699-1617
Page 7of10

Permit NC0036277
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 mailing address above. 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 21,2020,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/20 15/10/22/2015-24954/national-pollutant-discharge-elimination-
system-npdes-electronic-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 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.
