denied.
Summary of Changes and Rationale for Renewal
1. As requested by the Permittee for renewal, down -graded the current wetlands WWTP from Class
WPCS-2 to WPCS Class11, as approved on 27Apr2023 by NC Operator Certification Unit
(OCU) and Raleigh Regional Office (RRO).
2. Instream Monitoring for Total Nitrogen (TN) and Total Phosphorus (TP) — relaxed monitoring
from Monthly to Quarterly.
3. Lastly, we resorted your effluent monitoring table by Measurement Frequency, most -
often to least -often sampled [see Table A. (1)].

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.

Only the aquatic life standards listed above are expressed in dissolved form. Aquatic life
standards for Mercury and selenium are still expressed as Total Recoverable Metals due to
bioaccumulative concerns (as are all human health standards for all metals). It is still necessary
to evaluate total recoverable aquatic life and human health standards listed in 15A NCAC
213.0200 (e.g., arsenic at 10 µg/l for human health protection; cyanide at 5 µg/L and fluoride at
1.8 mg/L for aquatic life protection).

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.
Page 4 of 7

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.
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 1 Q 10 = 0.843 (s7Q 10, 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)xs7Q10, 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.
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.
Page 5 of 7

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 = (s7Q 10 + Qw) (Cwgs)-(s7Q 10) (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 s7Q10)
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:
IQ 10 = 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.
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.
10. Hardness and flow values used in the Reasonable Potential Analysis for this permit included:

Dear Mr. Hennessy,
Todd Ishee, Secretary
The North Carolina Department of Adult Correction (DAC) is herewith submitting the applicable EPA
Forms to renew the existing NPDES Permit reference above.
Attached please find
• A completed EPA Form 1;
• A completed EPA Form 2E
There has been some delay in turning in the subject NPDES renewal package to the DEQ. As explained
earlier to various DEQ staff, our organization which changed from the DOC to the DPS many years ago
has once again split and we are now under the DAC. The DAC has just completed the transition and
renaming the renaming various facility names.
We are requesting the removal / reduction of any effluent monitoring and sampling requirements while
still maintaining our regulatory compliance. We specifically ask the DEQ-DWR to determine if the fecal

Attention: Mr. John Hennessy 7 April 2023 Page 2 of 2
coliform and toxicity limitations can be removed. The treated wastewater from our facility is discharged
into relatively large body of water (Roanoke River). The subject wastewater after discharge is very well
or adequately oxygenated, achieving additional dilution purification. The dissolved oxygen deficit at that
time is eradicated and the dissolved oxygen concentration is well above 4 to 5 mg/L — adequate for the
fish / aquatic life.
Additionally, the DAC is requesting that this facility's grade level be changed from its current 'Grade II' to
its previous 'Biological WPCS - Grade I' status. The existing wetland treatment system does not consist
any major equipment or other treatment components very well falls under the'Grade I' classification. A
previous, ex -employee of our organization had requested to change the classification from Grade I to
Grade II; without any basis or facts. Therefore, the DAC is asking that the designation be changed back
to "Grade I Biological WWTP," as it was previously.
Evidently, it makes more sense to make this significant alteration while we renew the permit. If the DEQ
staff members need to visit the site to assess this information / fact, we would be happy to have them.
Thank you in advance for your kind assistance. Should you have any questions or need additional
details, please do not hesitate to contact me.

7.1 Use the space below to expand upon any of the above items. Use this space to provide any information you believe the
reviewer should consider in establishing permit limitations. Attach additional sheets as needed.
c Please REVIEW the ATTACHED COVER LETTER that contains pertinent information for the renewal of the permit.
The Department of Adult Correction (DAC) is seeking that this facility's grade level be changed from its current'Grade II'
to its previous 'Biological WPCS - Grade I' status. The existing wetland treatment system does not consist any major
c equipment or other treatment components very well falls under the 'Grade I' classification. A previous, ex -employee of
our organization had requested to change the classification from Grade I to Grade 11; without any basis or facts.
L
Therefore, the DAC is asking that the designation be changed back to "Grade I Biological WWTP," as it was previously.
Evidently, it makes more sense to make this significant alteration while we renew the permit. If the DEQ staff members
need to visit the site to assess this information / fact, we would be happy to have them.

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 -July 1992 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). Effluent
samples for self -monitoring purposes must be obtained during representative effluent discharge below all waste
treatment. The tests will be performed during the months of January, April, July and October.
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, DWQ Form AT-2 (original) is to be sent to the following address:

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 Environmental Sciences
Section at the address cited above.

=monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly
Jest requirement will revert to quarterly in the months specified 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.
Should any test data from either these monitoring requirements -or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms
submitted.
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.

Permit NCO027626 "
A. (4.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[NCGS 143-215.1 (b)]
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the Environmental Protection Agency (EPA). The Division anticipates that these regulations
will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this permit
(Standard Conditions for NPDES Permits):
• Section B. (11.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Signatory Requirements
Reporting
Records Retention
Monitoring Reports
1. Reporting [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall begin reporting 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 / Information Processing Unit-_
ATTENTION: Central Files / eDMR _
1617 Mail Sei�ice Center =
Raleigh, NC7699-1617
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.
Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR. Temporary waivers shall be valid for twelve (12) months
and shall thereupon expire. At such time, DMRs shall be submitted electronically to the Division unless the
permittee re -applies for and is granted a new temporary waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
Page 5 of 6

Permit NC0027626
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.
2. 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 H,
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://-Portal.ncdenr.org/web/wq/admin/bog/il)u/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:
7 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. "
3. Records Retention [Supplements Section D. (6.)]
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].
