A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B.0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 2.1 % at 5.2 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
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.
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
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
Page 4 of 8

Permit No. NC0029980
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.) ELECTRONIC REPORTING OF MONITORING REPORTS [NCGS 143-215.1 (b)]
[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 Section 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

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:

Attn: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Page 5 of 8

Permit No. NC0029980
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-
pol lutant-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

4. Instream Data Summary
Instream monitoring may be required in certain situations, for example: 1) to verify model predictions when
model results for instream DO are within 1 mg/1 of instream standard at full permitted flow; 2) to verify
model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other instream
concerns. Instream monitoring may be conducted by the Permittee, and there are also Monitoring
Coalitions established in several basins that conduct instream sampling for the Permittee (in which case
instream monitoring is waived in the permit as long as coalition membership is maintained).
If applicable, summarize any instream data and what instream monitoring will be proposed for this permit
action: The current permit requires instream monitoring for Dissolved Oxygen (DO) and Temperature. A
review of instream data from June 2014 through September 2016 indicates that the DO standard of 5 mg/L
was maintained. Data collected is within normal parameters for DO and temperature. Instream data is
summarized in tables 2 and 3. This draft permit maintains the same Instream monitoring requirements.

5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): The facility reported no limit
violations from June 2012 to March 2018.
Summarize the compliance record with aquatic toxicity test limits and any second species test results (past
5 years): Since 2013, the facility passed 17 of 17 quarterly chronic toxicity tests
Summarize the results from the most recent compliance inspection: The last facility inspection conducted
on July 2017 reported that the facility operations were found to be shut down and no flow is anticipated.
6. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and Mixing Zones
In accordance with 15A NCAC 2B.0206, the following streamflows are used for dilution considerations
for development of WQBELs: 1 Q 10 streamflow (acute Aquatic Life); 7Q 10 streamflow (chronic Aquatic
Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).
If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): NA
If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): NA
Oxygen -Consuming Waste Limitations
Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD= 30 mg/1 for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe how limits were developed: NA
Ammonia and Total Residual Chlorine Limitations
Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of
1.0 mg/1 (summer) and 1.8 mg/1 (winter). Acute ammonia limits are derived from chronic criteria, utilizing
a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non -Municipals.
Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection
of aquatic life (17 ug/1) and capped at 28 ug/1 (acute impacts). Due to analytical issues, all TRC values
reported below 50 ug/1 are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: The facility does
not have chlorination; therefore, no TRC limit. The NH3-N allowable concentration for summer and winter
exceeded 35 mg/L; therefore, monitor only. There are no proposed changes.

Reasonable Potential Analysis (RPA) for Toxicants
If applicable, conduct RPA analysis and complete information below.
The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality
standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent
effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC
RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero
background; 3) use of '/2 detection limit for "less than" values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
A reasonable potential analysis was conducted on effluent toxicant data collected between January 2014
and April 2017. Pollutants of concern included toxicants with positive detections and associated water
quality standards/criteria. Based on this analysis, the following permitting actions are proposed for this
permit:
• Effluent Limit with Monitoring. The following parameters will receive a water quality -based
effluent limit (WQBEL) since they demonstrated a reasonable potential to exceed applicable water
quality standards/criteria: NA
• Monitoring Only. The following parameters will receive a monitor -only requirement since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria, but
the maximum predicted concentration was >50% of the allowable concentration: NA
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since
they did not demonstrate reasonable potential to exceed applicable water quality standards/criteria
and the maximum predicted concentration was <50% of the allowable concentration: Total Zinc
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern.

If applicable, attach a spreadsheet of the RPA results as well as a copy of the Dissolved Metals
Implementation Fact Sheet for freshwater/saltwater to this Fact Sheet. Include a printout of the RPA
Dissolved to Total Metal Calculator sheet if this is a Municipality with a Pretreatment Program.
Toxicity Testing Limitations
Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in
accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits
issued to Major facilities or any facility discharging "complex" wastewater (contains anything other than
domestic waste) will contain appropriate WET limits and monitoring requirements, with several exceptions.
The State has received prior EPA approval to use an Alternative WET Test Procedure in NPDES permits,
using single concentration screening tests, with multiple dilution follow-up upon a test failure.
Describe proposed toxicity test requirement: A chronic WET limit at 2.1 % effluent will continue on a
quarterly frequency.

Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply with
EPA's mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a
wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and
industrial facilities with known mercury discharges. Given the small contribution of mercury from point
sources (-2% of total load), the TMDL emphasizes mercury minimization plans (MMPs) for point source
control. Municipal facilities > 2 MGD and discharging quantifiable levels of mercury (>1 ng/1) will receive
an MMP requirement. Industrials are evaluated on a case -by -case basis, depending if mercury is a pollutant
of concern. Effluent limits may also be added if annual average effluent concentrations exceed the WQBEL
value (based on the NC WQS of 12 ng/1) and/or if any individual value exceeds a TBEL value of 47 ng/1
Describe proposed permit actions based on mercury evaluation: Mercury is not a pollutant of concern for
this facility and the permittee did not test any mercury for this renewal. There are no proposed changes.
Other TMDLfNutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation within
this permit: NA
Other WOBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: NA
If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall
comply with in order to protect the designated waterbody: NA
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with 15A
NCAC 2H.0107(c)(2)(B), 40CFR 122.47, and EPA May 2007Memo: NA
If applicable, describe any water quality standards variances proposed in accordance with NCGS 143-
215.3(e) and 15A NCAC 2B. 0226 for this permit renewal: NA
7. Technology -Based Effluent Limitations (TBELs)
Industrials (if not applicable, delete and skip to next Section)
Describe what this facility produces: brewing and packing
List the federal effluent limitations guideline (ELG) for this facility: NA
If the ELG is based on production or flow, document how the average production/flow value was calculated:
NA
For ELG limits, document the calculations used to develop TBEL limits: NA
If any limits are based on best professional judgement (BPJ), describe development: The last waste load
allocations was completed in 1996. Limits for BOD and TSS were based in proposed effluent guidelines.
The guidelines were never finalized and the limits were modified in 2003 based on BPJ. The BOD
monthly and daily limits were based on concentrations of 38 mg/1 and 92 mg/1 respectively. TSS monthly
and daily limits were based on concentrations of 56 mg/1 and 135 mg/1 respectively. Current permit limits
Page 6 of 9

are 1648 lb/day monthly average and 39901b/day daily maximum for BOD and 24291b/day monthly
average and 58551b/day daily maximum for TSS.
Document any TBELs that are more stringent than WQBELs: NA
Document any TBELs that are less stringent than previous permit: NA
8. Antidegradation Review (New/Expanding Discharge):
The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegradation
review in accordance with 15A NCAC 2B.0201. Each applicant for a new/expanding NPDES permit
must document an effort to consider non -discharge alternatives per 15A NCAC 2H.0105( c)(2). In all
cases, existing instream water uses and the level of water quality necessary to protect the existing use is
maintained and protected.
If applicable, describe the results of the antidegradation review, including the Engineering Alternatives
Analysis (EAA) and any water quality modeling results: NA
9. Antibacksliding Review:
Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(1) prohibit
backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a
reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations
may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit (YES/NO): Yes
If YES, confirm that antibacksliding provisions are not violated: Based on RPA, no monitoring will be
required for Total Zinc.
10. Monitoring Requirements
Monitoring frequencies for NPDES permitting are established in accordance with the following
regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2)
NPDES Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance,
Reduced Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best
Professional Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not
considered effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti -
backsliding prohibitions would not be triggered by reductions in monitoring frequencies.
For instream monitoring, refer to Section 4.
Page 7 of 9

11. Electronic Reporting Requirements
The US EPA NPDES Electronic Reporting Rule was finalized on December 21, 2015. Effective
December 21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports
(DMRs) electronically. Effective December 21, 2020, NPDES regulated facilities will be required to
submit additional NPDES reports electronically. This permit contains the requirements for electronic
reporting, consistent with Federal requirements.

13. Public Notice Schedule:
Permit to Public Notice: 05/29/2018
Per 15A NCAC 2H .0109 & .0111, The Division will receive comments for a period of 30 days following
the publication date of the public notice. Any request for a public hearing shall be submitted to the
Director within the 30 days comment period indicating the interest of the party filing such request and the
reasons why a hearing is warranted.
14. Fact Sheet Addendum (if applicable):
Were there any changes made since the Draft Permit was public noticed (Yes/No): Yes
If Yes, list changes and their basis below:
Winston-Salem regional Office (WSRO) did make a comment on the draft renewal permit due to the fact
that the facility has been unoccupied for more than 1.5 years and it requires significant maintenance prior
to any future discharge. WSRO requested to add a condition that pre -startup inspection be conducted
before restarting the discharge.
In response, the following text has been added to the Supplement to Permit Cover Sheet: "At the
time of this permit renewal, the facility has been unoccupied for more than a year and a half. The
wastewater system is not operational, and will require significant maintenance prior to any future
discharge.
The permittee shall notify the NC DEQ Winston-Salem Regional Office (WSRO) at least 30
days prior to any planned restart of this treatment facility. WSRO staff approval is required prior
to any future discharge from this system."

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.
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 1Q10 using the formula 1Q10 = 0.843 (s7Q10, cfs) 0993
• 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.
Page 2 of 4

Permit No. NC0029980
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) + (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 =
1
Ctotal
1 + { [K ,] [ss(i+a_J [10-] )
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 sheet labeled DPCs.
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 s7Q10)
s7Q10 = 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
Page 3 of 4

Permit No. NC0029980
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.

Dissolved to Total Metal Calculator
Do NOT enter any data directly into thls spreadsheet.
Enter data onto "Table 1" under the Input Sheet and enter
"Effluent Hardness" under the Data Sheet.
In accordance with 40 CFR 122.45 (c ), permits are, have and
must be written as total metals.
This calculator has been inserted into the RPA to calculate Total
Metal allowable allocations once Table 1 has been completed
(Input Sheet) and Effluent hardness has been entered (Data
Sheet).
1) Following the spreadsheet from left to right. First
the allowable allocations for the dissolved metals will
appear for all the metals listed once Table 1 is complete and
effluent hardness entered. Use a default value of 25 mg/L if
no hardness data is available. Second, the
Dissolved Metal allocations are divided by the Translators to
determine the Total Metals that can be allocated to the
Permittee. These Total Metals values are automatically
inserted into Table 2 and are the allowable Total Metal
allocations determined for the Permittee prior to allowing
for dilution. See Input sheet Table 2. The final acute and
chronic values shown under the RPA sheet are the Total
Metal values listed in Table 2 divided by the acute and
chronic IWC, respectively.
2) The Translators used in the freshwater RPA are the Partition
Coefficients published by US EPA in 1984. They are TSS
dependent equations and can be found listed with the WQS
hardness dependent equations under the sheet labeled
Equations. A fixed TSS value of 10 mg/L is used to calculate
the Translator values.
3) Pretreatment Facilities- PERCS will need a copy of the
Dissolved to Total Metal Calculator spreadsheet and the
RPA sheet along with the Final Permit. Pretreatment
Facilities are required to renew their Headwords Analysis
after renewal of their permits. Since all their metal
allocations are likely to change PERCS needs to see any new
metal permit limits and the allowable allocations for the
dissolved metals to assess Maximum Allowable Headworks
Loading (MAHL) numbers for each metal based on the
Combined Hardness values used in the permit writers RPA
calculations.
4) For Cadmium, Lead, Nickel, Chromium and Beryllium, if all
the effluent sampling data for the last three to five years
shows the pollutant at concentrations less than the Practical
Quantitative Level (PQL), it is not likely a limit or monitoring
will be put in the permit. However, if the estimated NPDES
permit limit is less than the Practical Quantitative Limit
(particularly, Cadmium and Lead) and the pollutant is
believed to be present, to assess compliance with the new
standards and for future pen -nit limit development,
monitoring for the pollutant will be required. If the facility is
monitoring for the pollutant in its Pretreatment LTMP, no
monitoring is needed in the permit.
5) For monitoring and compliance purposes If Total Chromium

Good morning Susan,
That's totally true. The final flow cessation was April 2017 and they are trying to sell the facility. However, they want to
retain their permit since it is going to be a selling point. In order to renew their permit I need to have their toxicity test
results since 2013. Are those all the results that you have? I would appreciate if you send me all the results since 2013.

Yes, the lagoons (2 of them) were properly closed per the Division's Closure Policy. I did a closure inspection to confirm
their report at that time.
They chose to utilize the lagoon closure option of converting the two lagoons to freshwater ponds. All wastewater and
sludge was removed. The rainwater that was present following the closure was tested to demonstrate no waste was
contained. The old wastewater inlets were closed off. Only rainwater enters the structures now.
They did this with hopes that someday the property would be purchased, and the new owners could go through the
process to certify the lagoons back to receiving wastewater. I assume they are still wanting to keep the NPDES permit
and modify it to zero discharge. Paul DiMatteo is handling the NPDES part up there now.
Please let me know if you have any questions or need anything further on the closures.
Thanks,
Patrick

Good morning Susan,
That's totally true. The final flow cessation was April 2017 and they are trying to sell the facility. However, they want to
retain their permit since it is going to be a selling point. In order to renew their permit I need to have their toxicity test
results since 2013. Are those all the results that you have? I would appreciate if you send me all the results since 2013.

Hi Qais,
I was told by the Regional Office that it had officially shutdown in April of last year.
Was that incorrect or are they starting up operations again?
Here is a list of their aquatic tox results.

Hi Susan,
I am currently working on MillerCoors Permit (NC0029980) and for some reason couldn't find any toxicity test results in
the PDF that you sent. However, they submitted a hard copy of some of their toxicity results. If you have a summary of
their results, I would appreciate if you email them to me.

I am wondering if you have the results of 2"d species toxicity test for Raeford WWTP (NC0026514) which was done on
5/9/2012. The PDF you sent covers 2014 through 2018. If so, could you please email me a copy of the results.

Permitting Section
MillerCoors LLC (MillerCoors) is pleased to provide this submittal to the North Carolina
Department of Environmental Quality (NCDEQ) concerning a change in status at the
MillerCoors Eden Brewery located at 863 East Meadow Road in Eden, North Carolina.
Specifically, this letter is to serve as a request to place the facility's current National
Pollutant Discharge Elimination System (NPDES) discharge permit (Permit No.
NC0029980) into an "inactive" status as a result of facility closure.
It should be noted that the MillerCoors Eden Brewery facility ceased all manufacturing in
September 2016. Facility structures and process equipment were gradually
decommissioned and cleaned by facility closure, April 2017. To conclude the facility
closure, operations at the facility wastewater treatment plant were ultimately terminated,
including the acceptance and processing of all influent from the facility and the discharge of
effluent out of the facility as of April 30, 2017. Subsequently, the facility received a final
lagoon closure inspection and formal response dated March 2, 2017 in which the NCDEQ
considered the lagoon system as having been "properly closed." Based on the completed

r,
facility closure and prior discussions with the NCDEQ regarding foreseen uses of the
NPDES permit by future potential occupants, MillerCoors is requesting to retain the facility
NPDES permit, however in an "inactive" state. This request is submitted to NCDEQ for
immediate consideration as of the final flow cessation date of April 30, 2017.
Should you have any questions, please do not hesitate to contact me at [phone] or
via e-mail at [e-mail].

Enclosed is one (1) signed original copy and two (2) copies of the application.
It should be noted that the MillerCoors - Eden Brewery has ceased all manufacturing
effective September 2016. MillerCoors is currently implementing facility closure work and
plans to complete closure by March 31, 2017. Consequently, the discharge of processed
wastewater will not be expected to continue beyond this closure date and a notice of
termination will be provided 90 days prior to permanent closure. However, MillerCoors
has decided to submit this application in the event that closure activities are delayed past
April 30, 2017.

SLUDGE MANAGEMENT PLAN
MillerCoors, LLC
Eden, North Carolina
Sludge Management Summary:
The facility generated residual sludge material is handled and managed in accordance with
the conditions and parameters set forth by permits, NCDEQ — DWQ Permit No.
WQ0001347 (see Attachment A for permit conditions).
Per NCDEQ — DWQ Permit No. WQ0001347, the residual solids generated as part of the
Eden Brewery biological wastewater treatment system are categorized as residual solids of
exceptional quality (503 exempt) and are permitted to be distributed or land applied.
Performance standard requirements for residuals include ceiling and monthly average
concentration limits for select pollutants. To ensure residual characteristic compliance
under NCDEQ - DWQ Permit No. WQ0001347, monitoring is currently taking place at a
frequency of 1/60 days (6 times per year) based on the current permitted volumes.
The facility residual sludge materials are removed and transported offsite in bulk by a
licensed biosolid land application contractor. The residuals are beneficially reused as a soil
additive on selected pre -approved farms in North Carolina. Recipient farms are deemed
qualified to receive facility residuals upon review of the most recent soil analysis report
ensuring the need for the residual product and after a completed onsite inspection (see
Attachment B for inspection form). Notes made of streams, rivers, wells, dwellings, and
other environmental factors can dictate the rates of application. Each qualified recipient
farm is provided with a MillerCoors Farm -On Guaranteed Analysis Statement (see
Attachment C for Product Label).
