Data Review
• reviewed BIMS compliance data from 2019 through present. No violations proceeded to NOV.
• reviewed Discharge Summary, BIMS database.
• reviewed Ammonia (NH3 as N) compliance history: Average 1.4 mg/L; Max 4.9 mg/L;
Min 0.1 mg/L (count 175 samples, Jan2019 thru Apr2022).
• reviewed permit limits considering this is not a publicly owned treatment works (POTW);
see IWC via WLA concerning Ammonia limited as a toxicant (15A NCAC 2B .0205).
Permitting Strategy
NH3 Limits Considering Toxicity @ 0.300 MGD
1. Previous NH3 limits for summer were permitted at 2.7 mg/L Monthly Average (MA) & 13.5
mg/L Daily Max (DM). The DM = MA times five (5) for a non-POTW. Previous NH3 winter
limits were 4.0 mg/L MA and 20.0 mg/L DM. However, DWR finds no justification for the
previous winter MA limit of 4.0 mg/L. Therefore, DWR assumes that 4.0 mg/L MA was
permitted in error [best professional judgement (BPJ)].
2. BIMS records only a summer receiving steam flow 7Q10 of 0.1 cfs. For renewal therefore,
DWR considered 1.0 cfs for both summer and winter stream flows (see 0.300 WLA). This
results in summer chronic limits (MA) of 2.7 cfs and winter chronic limits (MA) of 5.2 cfs.
Page 1 of 7

3. It follows that renewal DMs are permitted as summer 5 x 2.7 mg/L = 13.5 mg/L DM, and
winter 5 x 5.2 = 26.0 mg/L DM [see permit Section A. (1.)]. Because it is a technical
correction of previous winter MA 4.0 mg/L, anti -backsliding does not apply.
NH3 Limits Considering Toxicity @ 0.800 MGD
1. Summer limits [01Apr — 310ct] — were previously calculated (2017) at MA 2.0 mg/L & DM
10.0 mg/L [DM = MA times five (5) for a non-POTW]. Previous winter MA limit were 4.3
mg/L MA and 21.5 mg/L DM.
2. Because BIMS records receiving steam show for summer only [7Q10 flow = 0.1 cfs], this
renewal considered 1.0 cfs for both summer and winter flows (see 0.800 WLA). This results
in summer limits of 1.6 mg/L MA times 5 = 8.0 mg/L DM. However, these limits are judged
unattainable by Best Available Technology (BAT). Therefore, they remain unchanged for
renewal at 2.0 mg/L MA and (times 5) 10.0 mg/L DM [see permit Section A. (2.)].
4. Per the 0.800 WLA, winter MA limits calculate as 3.1 mg/L and (times 5) = 15.5 mg/L DM.
Likewise, these limits are judged unattainable (BAT). For renewal therefore, they remain
unchanged from the previous as BAT, 4.3 mg/L MA and (times 5) 21.5 mg/L DM [see permit
Section A. (2.)].

NPDES Implementation of Instream Dissolved Metals Standards — Freshwater Standards
The NC 2007-2015 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Commission (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016, with some exceptions. Therefore, metal limits in draft
permits out to public notice after April 6, 2016 must be calculated to protect the new standards - as
approved.

General Information on the Reasonable Potential Analysis (RPA)
The RPA process itself did not change as the result of the new metals standards. However, application
of the dissolved and hardness -dependent standards requires additional consideration in order to
establish the numeric standard for each metal of concern of each individual discharge.
The hardness -based standards require some knowledge of the effluent and instream (upstream)
hardness and so must be calculated case -by -case for each discharge.
Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c).
The discharge -specific standards must be converted to the equivalent total values for use in the RPA
calculations. We will generally rely on default translator values developed for each metal (more on
that below), but it is also possible to consider case -specific translators developed in accordance with
established methodology.
RPA Permitting Guidance/WQBELs for Hardness -Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable
standards and the critical low -flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value (chronic or acute), the
discharge has reasonable potential to exceed the standard, which warrants a permit limit in most cases.
If monitoring for a particular pollutant indicates that the pollutant is not present (i.e. consistently
below detection level), then the Division may remove the monitoring requirement in the reissued
permit.
Page 4 of 7

1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles
the following information:
• Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically
calculates the 1 Q 10 using the formula 1Q10 = 0.843 (s7Q10, cfs) 0.993
• Effluent hardness and upstream hardness, site -specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness -dependent metal of concern and
for each individual discharge, the Permit Writer must first determine what effluent and
instream (upstream) hardness values to use in the equations.
The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for any
hardness data and contacts the Permittee to see if any additional data is available for instream
hardness values, upstream of the discharge.
If no hardness data is available, the permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum limits on the
hardness value used for water quality calculations are 25 mg/L and 400 mg/L, respectively.
If the use of a default hardness value results in a hardness -dependent metal showing reasonable
potential, the permit writer contacts the Permittee and requests 5 site -specific effluent and
upstream hardness samples over a period of one week. The RPA is rerun using the new data.
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness (chronic)
= (Permitted Flow, cfs *Avg. Effluent Hardness, mg/L) x (s7Q10, cfs *Avg. Upstream Hardness, mg/L)
(Permitted Flow, cfs + s7Q10, cfs)
The Combined Hardness for acute is the same but the calculation uses the 1Q10 flow.
3. The permit writer converts the numeric standard for each metal of concern to a total
recoverable metal, using the EPA Default Partition Coefficients (DPCs) or site -specific
translators, if any have been developed using federally approved methodology.
EPA default partition coefficients or the "Fraction Dissolved" converts the
value for dissolved metal at laboratory conditions to total recoverable metal
at in -stream ambient conditions. This factor is calculated using the linear
partition coefficients found in The Metals Translator: Guidance for
Calculating a Total Recoverable Permit Limit from a Dissolved Criterion
(EPA 823-B-96-007, June 1996) and the equation:
Cdiss =
Ctotal
1
1 + 1 [Kpo] [SS(1+a)] [10-6] }
Where:
ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L
used, and
Kpo and a = constants that express the equilibrium relationship between
dissolved and adsorbed forms of metals. A list of constants used for each
hardness -dependent metal can also be found in the RPA program under a
Page 5 of 7

4. The numeric standard for each metal of concern is divided by the default partition coefficient
(or site -specific translator) to obtain a Total Recoverable Metal at ambient conditions.
In some cases, where an EPA default partition coefficient translator does not exist (ie. silver),
the dissolved numeric standard for each metal of concern is divided by the EPA conversion
factor to obtain a Total Recoverable Metal at ambient conditions. This method presumes that
the metal is dissolved to the same extent as it was during EPA's criteria development for
metals. For more information on conversion factors see the June, 1996 EPA Translator
Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable
concentration (permit limits) for each pollutant using the following equation:
Ca = (s7Q10 + Qw) (Cwqs) — (s7Q10) (Cb)
Qw
Where: Ca = allowable effluent concentration (µg/L or mg/L)
Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L)
Cb = background concentration: assume zero for all toxicants except NH3* (µg/L or
mg/L)
Qw = permitted effluent flow (cfs, match s7Q 10)
s7Q 10 = summer low flow used to protect aquatic life from chronic toxicity and human
health through the consumption of water, fish, and shellfish from noncarcinogens (cfs)
* Discussions are on -going with EPA on how best to address background
concentrations
Flows other than s7Q10 may be incorporated as applicable:
1Q10 = used in the equation to protect aquatic life from acute toxicity
QA = used in the equation to protect human health through the consumption of water,
fish, and shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of
concern. Data entered must have been taken within four and one-half years prior to the date of
the permit application (40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile
upper concentration of each pollutant. The Predicted Max concentrations are compared to the
Total allowable concentrations to determine if a permit limit is necessary. If the predicted max
exceeds the acute or chronic Total allowable concentrations, the discharge is considered to
show reasonable potential to violate the water quality standard, and a permit limit (Total
allowable concentration) is included in the permit in accordance with the U.S. EPA Technical
Support Document for Water Quality -Based Toxics Control published in 1991.
7. When appropriate, permit writers develop facility specific compliance schedules in accordance
with the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to Alexis Strauss
on 40 CFR 122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and
hexavalent chromium Water Quality Standards. As a cost savings measure, total chromium
data results may be used as a conservative surrogate in cases where there are no analytical
results based on chromium III or VI. In these cases, the projected maximum concentration
(95th %) for total chromium will be compared against water quality standards for chromium III
and chromium VI.
Page 6 of 7

9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are
inserted into all permits with facilities monitoring for hardness -dependent metals to ensure the
accuracy of the permit limits and to build a more robust hardness dataset.

A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[NCGS 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 DENR / 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.
Page 5 of 7

Permit NC0022985
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-elimmation-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.

Permit NC0022985
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:
"I 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 permrttee 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].
