Subject: Review of NPDES Permit DRAFT
NC0003671, WWTP Grade PC-1
Greensboro Terminal II
Gilford County
The Division of Water Resources (DWR or the Division) received on February 8, 2021 your application
to renew the subject permit. Please carefully review the attached renewal draft to ensure your
understanding of its limits and monitoring conditions, and to correct errors, if any.
Concurrent with this notification, the Division will solicit public comment on this draft by publishing a
notice in newspapers having circulation in the general Guilford County area, as required by the NPDES
Program. Please submit your written comments (if any), to my attention, NCDEQ / DWR /NPDES no
later than May 24, 2021 (approximately 30 days after receiving this document). We welcome your
written comments, but they are not mandatory.
Whole Effluent Toxicity (WET) — Please note that the Division has increased WET testing from Annually
to Quarterly [see section A. (1.)] in compliance with new permitting policy. The Division has judged that
WET testing is needed at minimum Quarterly to protect surface water quality, and we are currently
converting permits statewide to Quarterly at renewal.
Database Evaluation. Since last renewal, the Division understands that Magellan has made no significant
alterations to treatment/pollution-prevention processes. We have therefore only updated the site map and
permit texts.
In keeping with current NPDES Permitting Guidance, DWR evaluated monitoring data by applying
reasonable potential analyses (RPAs) as required by the EPA. Each parameter of concern (POC) is
considered for its potential to exceed its respective surface water -quality standard.
Renewal Summary — DWR updated the following:
• Turbidity: monitoring continues Monthly; added limit based on RPA.
• Benzene: RP = yes; Monthly monitoring; added limit
• Ethylbenzene, and Total Xylenes: No RP; reduced monitoring to Quarterly
• EPA Method 625 monitoring continues Semi -Annually as a spot check for
additional POCs.
• MTBE: RP = yes; Monthly monitoring with limit

Draft Permit Review Apri12021
Monthly Report Submittals: Federal regulations require electronic submittal of all program reports
and Monthly Discharge Monitoring Reports (DMRs); see Permit Condition A. (3.). Our records
show that Magellan has successfully registered for the Electronic Discharge Monitoring Report
(eDMR) program. If you have completed and submitted to DWQ an Electronic Signature
Agreement, you are no longer required to submit DMR hardcopy as back-up to the eDMR.
The NPDES standard conditions (Parts II, III, and IV), are part of this permit but are not included in this
draft document (cover, map, and Part I). The conditions are identical to your current permit except that
agency and division names have been updated. 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.
Following the mandatory 30-day Public Comment period, the Division will review all pertinent comments,
if any, and take appropriate action prior to issuing an NPDES permit final.
If you have questions, please email the undersigned at [[e-mail]]. In support of mandated
emergency response to Covid 19, most of NC state government currently functions remotely, therefore
correspondence via email is preferred.
Respectfully,

Permit NC0003671
A. (2.) ACUTE TOXICITY — 24-HOUR STATIC TEST (Quarterly)
The permittee shall conduct acute toxicity tests on a Quarterly basis using protocols defined 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). The monitoring shall
be performed as a Fathead Minnow (Pimephales promelas) 24-hour static test. The effluent concentration
at which there may be at no time significant acute mortality is 90 % (defined as treatment two in the
procedure document).
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.
The parameter code for Pimephales promelas is TGE6C. All toxicity testing results required as part of
this permit condition will be entered electronically using the Division's eDMR system for the month in
which it was performed, using the appropriate parameter code. Additionally, DWR Form AT-2 (original)
is to be sent to the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Or, results can be sent to the email, ATForms.ATBAncdenr.gov.
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, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature.
Total Residual Chlorine (TRC) 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 any month, 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. Upon submission of a valid test, this monthly test requirement will
revert to quarterly in the months specified above.
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.

Permit NC0003671
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.
USE OF A DIFFERENT TEST ORGANISM
The permittee may request the use of a different test organism upon documentation that the alternate test
organism would provide an equal or greater level of protection and is appropriate based on the
characteristics of the discharge and receiving stream. Such documentation would consist of one of the
following:
1. For saltwater classified streams, a fathead minnow may be assigned as the acute testing species if
the salinity of the receiving stream at the point of discharge is <5 ppt throughout the tidally
influenced cycle. This determination may be based on the best professional judgment of DWQ
staff or data collection provided by the permittee and approved by DWQ staff. This evaluation
should include vertical profiles of salinity/conductivity measurements at both high tide and low
tide over several 24-hr cycles.
2. Three consecutive "side -by -side" tests with results indicating that the alternate test organism is as
or more sensitive to the facility's effluent. Each test series would consist of two separate toxicity
tests conducted on the same sample of effluent with the length of exposure specified by the permit,
the only difference between the tests being the organism used.
3. An alternate plan developed by the permittee and approved by the Aquatic Toxicology Unit that
demonstrates an equal level of protection is offered by the test organism.
For items 2 and 3, it must also be demonstrated that viable and standardized culture techniques are
available for that organism and standardized testing methodologies have been developed and validated.
This demonstration should meet guidance provided by EPA in Section 6 of EPA-821-R-02-012, Short
Term Methods for Estimating the Acute Toxicity of Effluents and Receiving Waters to Freshwater
Organisms Fifth Edition, 2002. Requests to use a different test organism and supporting documentation
should be sent to NC DWQ, ESS at the address listed above.
A. (3.) ELECTRONIC REPORTING OF 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 NPDESPermits):
• 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)]
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.

Permit NC0003671
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 AnnualReports; 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-d ischarge-elimination-system-npdes-electronic-repo rting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.

Permit NC0003671
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: http://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (IL) (b) and Supersedes Section B. (11.) (d)]
