IN THE MATTER OF
NORTH CAROLINA
NPDES PERMIT NO. NC0020575
PERMIT NO. WQ0029169
PERMIT NO. WQCS00129
HELD BY
THE TOWN OF MOUNT OLIVE
SPECIAL ORDER BY CONSENT
EMC SOC WQ S20-0021
Pursuant to provisions of North Carolina General Statute (G.S.) 143-215.2 and G.S. 143-215.67,
this Special Order by Consent is entered into by the Town of Mount Olive, hereinafter referred to
as the Town, and the North Carolina Environmental Management Commission, an agency of the
State of North Carolina created by G.S. I43B-282, and hereinafter referred to as the Commission:
I. The Town and the Commission hereby stipulate the following:
(a) The Town holds North Carolina NPDES Permit NC0020575 for operation of an existing
two million gallon per day (mgd) wastewater treatment works and for making an outlet
therefrom for the discharge of one mgd treated wastewater to the Northeast Cape Fear
River, Class C;Sw waters of this State in the Cape Fear River Basin.
The Town also holds Non -Discharge Permit WQ0029169 for operation of a 560,893
gallons per day reclaimed water generation, distribution, and utilization system but is
unable to operate the system at its design capacity. The failure to manage this system has
contributed to noncompliance of the wastewater treatment plant, which discharges the
excess flow to the Cape Fear River in violation of its monthly effluent flow limits as set
forth in NC0020575.
Additionally, the Town holds Permit Number WQCS00129 for operation and
maintenance of approximately 32 miles of gravity sewer, 5 miles of force main, and 15
duplex pump stations to make a complete and functional collection system. The Town
has had persistent issues with inflow and infiltration within this system, which
contributes to flow limit violations at the WWTP. The Town has also received notices of
violation due to sanitary sewer overflows (SSOs) at the influent pump station and
manhole at the WWTP.
The Town continues to be in noncompliance with permit conditions and limits for flow
of their NPDES Permit NC0025075. The Town seeks to discharge an average of 2.4
MGD to the Northeast Cape Fear River while repairs and enhancements to the spray
irrigation facility permitted under WQ0029169 are completed. During construction of
the improved system, the non -discharge system will be unable to receive any flow,
necessitating additional discharge into surface waters. The persistent inflow and
infiltration issues within the collection system are further contributing to flows beyond

Town of Mount Olive — Mount Olive WWTP
EMC SOC WQ S20-0021
Page 2 of 8
the current capacity of the WWTP.
This SOC relaxes the flow limits set forth in the NPDES permit to 2.4 mgd while
maintaining the permitted nutrient loads. There will be no net increase of pollutants to the
River with this increased flow.
Compliance will require preparation of plans and specifications for construction and
operation of additional treatment works and influent pump station improvements.
(b) Noncompliance with final effluent limitations constitutes causing and contributing to
pollution of the waters of this State named above, and the Town is within the jurisdiction
of the Commission as set forth in G.S. Chapter 143, Article 21.
(c) The Town has secured a grant or has otherwise secured financing for planning, design,
and construction/repairs of the following:
•
i. Improvements to the influent pump station, including construction of a new 18-inch force
main.
ii. Removal of influent bypass pump station from service.
iii. Modification of the WWTP headworks to receive increased flow from the improved
influent pump station.
iv. Rehabilitation of two of the four WWTP tertiary filters to increase filter efficiency, return
the filters to their design flowrates, and eliminate frequency of bypass.
v. Installation of a new Parshall flume to increase the accuracy of effluent flow monitoring.
vi. Upgrade of the existing irrigation pump station, and irrigation system controls, to be
compatible with the proposed spray irrigation system. A new transfer pump station
wetwell will be installed. •
vii. The existing sycamore tree crop and drip irrigation system will be replaced with a grass
crop and spray irrigation system.
(d) Since this Special Order is by Consent, neither party will file a petition for a contested
case or for judicial review concerning its terms.
2. The Town, desiring to comply with the Permits identified in paragraph 1(a) above, hereby
agrees to do the following:

Notes:
1. Submit discharge monitoring reports electronically using the NC DWR's eDMR application system. See
section A. (5.).
2. The monthly average effluent BOD5 and TSS concentrations shall not exceed 15 % of respective influent
value (i.e., 85% removal is required).
3. Effluent monitoring and limitation only apply if chlorine or a chlorine derivative is added to the waste stream
during treatment. The Division shall consider all effluent TRC values reported below 50 µg/L to be in
compliance with the permit. However, the permittee shall continue to record and submit all values reported
by a North Carolina certified laboratory (including field certified), even if these values fall below 50 µg/L.
4. For a given wastewater sample, TN = TKN + NO3-N + NO2-N, where TN is total nitrogen, TKN is total
Kjeldahl Nitrogen, and NO3-N and NO2-N are nitrate and nitrite nitrogen, respectively.
5. Chronic Toxicity P/F (Ceriodaphnia) @ 90%, March, June, September, December [see A. (2.)].
6. NCDEQ will not enforce pass/fail limits for tests that take place for the quarters where oxidation ditches
and tertiary filters are offline for service. In all other quarters, the Town must comply with toxicity
requirements.
7. The permittee shall perform three Effluent Pollutant Scans during the term of this permit [see A. (4.)].
8. Effluent Total Hardness sampling should be performed in conjunction with sampling for hardness dependent
metals (cadmium, copper, lead, nickel, silver, and zinc).
9. See A. (3.) for instream monitoring requirements.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

A. (2.) CHRONIC TOXICITY P/F 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 90% at 2.4 MGD flow regime.
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 March, June, September and December. 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 on the Effluent
Discharge Monitoring Form (MR-1) 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:
Attention: 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: [e-mail].
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 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,
monitoring will be required during the following month. 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 this monitoring requirement 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, minimum control organism reproduction, 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. (3.) INSTREAM MONITORING REQUIREMENTS [15A NCAC 02B .0500 et seq.]
Upstream samples shall be collected at least 50 feet from the outfall. Downstream samples shall
be collected at SR 1937 and at Highway 403.

Supplemental-Form
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. (5.) 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
• 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. Until such time that
the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting
Regulation (CROMERR), permittees will be required to submit all discharge monitoring data
to the state electronically using eDMR and will be required to complete the eDMR submission
by printing, signing, and submitting one signed original and a copy of the computer printed
eDMR 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
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/2015/ 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.
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. (11.) (b) and Supersedes Section B.
(11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in
Part II, Section B. (11.)(a) or by a duly authorized representative of that person as described in
Part II, Section B. (11.)(b). A person, and not a position, must be delegated signatory authority
for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR
user account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please
visit the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall
make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF
CERTIFICATION WILL BE ACCEPTED:

"1 certify, under penalty of law, that this document and all attachments were prepared under
my direction or supervision in accordance with a system designed to assure that qualified
personnel properly gather and evaluate the information submitted. Based on my inquiry of the
person or persons who manage the system, or those persons directly responsible for gathering
the information, the information submitted is, to the best of my knowledge and belief true,
accurate, and complete. I am aware that there are significant penalties for submitting false
information, including the possibility of fines and imprisonment for knowing violations."
5. Records Retention (Supplements Section D. (6.)1
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
submissions. These records or copies shall be maintained for a period of at least 3 years from the
date of the report. This period may be extended by request of the Director at any time [40 CFR
122.41].
