Dear Mr. Sparks:
The Division of Water Resources (the Division) hereby issues thea ttached NPDES permit for the an
facility. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency
dated October 15, 2007, or as subsequently amended.
We have made the following updates to your previous permit:
1. The facility map has been updated. The location of Outfall 001 is corrected to the following:
Latitude: 360 17' 46" (36.296111)
Longitude -79' 29' 3 1 " (-79.491944)
2. Regulatory citations have been added.
3. Effluent quarterly monitoring for Total Hardness has been added. Please see discussion below for
more information. Effluent hardness sampling should be performed in conjunction with sampling for
hardness dependent metals (Lead). Please note that since the outfall location is under zero flow
conditions, no instream hardness sampling will be required.
4. For all parameters with limits both monthly average limits and daily maximum limits have been
applied. The US EPA requires both a Monthly Average and a Daily Maximum for parameters that are
limited [40 CFR 122.45 (d.)]. 5. The limits for Isopropyl Ether (µg/L), 1,2-Didhloroethane (µgfL) and Naphthalene (µg2) have been
updated to 10 mglL, 5 µg/L and 6 µgIL, respectively.
6. Monitoring of Phenol has been changed to Total Recoverable Phenolics (parameter code 32730).
7. Electronic reporting of discharge monitoring reports (eDMR) has been added in Section A. (2.).
We have made the following updates for the final permit:
S. The flow limit of 0.009 MGD was corrected to be a monthly average limit.
The NC 2007-2014 Water Quality Standard (W QS) Triennial Review was approved by the NC
Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently approved
the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water Resources NPDES
Permitting Unit is required to implement the new dissolved metal standards in all permits public noticed after
April 6, 2016.

The new standards for most metals include acute standards. The freshwater standards for several metals are
expressed as the dissolved form of the metals, and seven metals have hardness -dependent equations. As a
result, the NPDES Permitting Unit will need site -specific effluent hardness data and instream hardness data,
upstream of the discharge, for each facility monitoring these metals in order to calculate permit
limitations. Effluent hardness has been added to this permit at a monitoring frequency of quarterly. No
instream monitoring will be required due to zero flow conditions. See Section A. (L) Effluent Limitations and
Monitoring Requirements.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing, upon written request submitted within thirty
(30) days after receiving this letter. Your request must take the form of a written petition conforming to
Chapter 150B of North Carolina General Statutes, and you must file it with the Office of Administrative
Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is
made, this permit shall remain final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or any
other Federal, State, or Local governmental permits that may be required.
If you have questions, or if we can be of further service, please contact Derek Denard at
[[e-mail]] or call [phone].

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

RENEWAL SUMMARY: This permit reflects discharge at Outfall 001. DWR updated the following:
1. The facility map has been updated. The location of Outfall 001 is corrected to the following:
Latitude: 36017' 46" (36.296111)
Longitude -790 29' 3 1 " (-79.491944)
2. Regulatory citations have been added.
3. Effluent quarterly monitoring for Total Hardness has been added. Please see discussion below for more
information. Effluent hardness sampling should be performed in conjunction with sampling for hardness
dependent metals (Lead). Please note that since the outfall location is under zero flow conditions, no
instream hardness sampling will be required.
4. For all parameters with limits both monthly average limits and daily maximum limits have been applied.
The US EPA requires both a Monthly Average and a Daily Maximum for parameters that are limited [40
CFR 122.45 (d.)].
5. The limits for Isopropyl Ether (µg/L), 1,2-Dichloroethane (µg/L) and Naphthalene (µg/L) have been
updated to 10 mg/L, 5 µg/L and 6 µg/L, respectively.
6. Monitoring of Phenol has been changed to Total Recoverable Phenolics (parameter code 32730).
7. Electronic reporting of discharge monitoring reports (eDMR) has been added in Section A. (2.).

RPA: 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 V2 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.
8. A reasonable potential analysis was conducted on effluent toxicant data collected between Dec2012-
May2017. Pollutants of concern included toxicants with positive detections and associated water quality
standards/criteria. Based on this analysis, limits for Isopropyl Ether (µg/L), 1,2-Dichloroethane (µg/L) and
Naphthalene (µg/L) have been updated to 10 mg/L, 5 µg/L and 6 µg/L, respectively. Lead will not receive a
lmit at this time because there was no detection and no effluent hardness data available to set a limit.

OUTFALL 001:
The location of Outfall 001 in the previous permit and BIMS is not near the facility property. The
coordinates [369 T46"N, 7912942"W] on a property not indicated on the original permit application. Plans
with the original application proposed piping it closer to a spring across several properties.
As noted in the July 28, 2010 inspection after the treatment system was constructed:
The effluent is discharged into dry ditch along the store owner's driveway. Ultimately, the ditch
discharges to an unnamed tributary of Country Line Creek in the Roanoke River Basin.

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/WOBELs 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, 7Q 10 (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.
Fact Sheet
Renewal 2017 — NPDES Permit NC0088692
Page 8

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) + (s7Q 10. cfs *Avg. Upstream Hardness, mg/L)
(Permitted Flow, cfs + s7Q 10, cfs)
The Combined Hardness for acute is the same but the calculation uses the IQ 10 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:
C iss - 1
Ctotal 1 + { [Kpol [ssit+ai] [10�1 }
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 = (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 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)
Fact Shect
Renewa12017 — NPDES Pennit NCO088692

* Discussions are on -going with EPA on how best to address background concentrations
Flows other than s7Q 10 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.

Dear Mr. Sparks:
In response to your request to renew the subject NPDES permit, the Division of Water Resources (DWR or the Division)
hereby transmits this draft for your review and comment. Please review this document to assure your understanding of
the permit limits and monitoring conditions, and to correct errors, if any.
http•//edocs dep nc gov/WaterResources/0/doc/556374/Pagel aspx?searchid=d84bd65c-1ad6-4ebb-9825-
77f24bb3c14b
We have made the following updates to your previous permit:
1. The facility map has been updated. The location of Outfall 001 is corrected to the following:
Latitude: 362 17' 46" (36.296111)
Longitude -792 29' 31" (-79.491944)
2. Regulatory citations have been added.
3. Quarterly Total Hardness monitoring has been added for the effluent. Please see discussion below for more
information. Effluent hardness sampling should be performed in conjunction with sampling for hardness
dependent metals (Lead). Please note that since the outfall location is under zero flow conditions, no instream
hardness sampling will be required.

4. For all parameters with limits both monthly average limits and daily maximum limits have been applied. The US
EPA requires both a Monthly Average and a Daily Maximum for parameters that are limited [40 CFR 122.45 (d.)].
5. The limits for Isopropyl Ether (µg/L),1,2-Dichloroethane (µg/L) and Naphthalene (µg/L) has been updated to 10
mg/L, 5 µg/L and 6 µg/L, respectively.
6. Monitoring of Phenol has been changed to Total Recoverable Phenolics (parameter code 32730).
7. Electronic reporting of discharge monitoring reports (eDMR) has been added in Section A. (2.).
The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC Environmental
Management Committee (EMC) on November 13, 2014. The US EPA subsequently approved the WQS revisions on April
6, 2016 with some exceptions. The NC Division of Water Resources NPDES Permitting Unit is required to implement the
new dissolved metal standards in all permits public noticed after April 6, 2016.
The new standards for most metals include acute standards. The freshwater standards for several metals are expressed
as the dissolved form of the metals, and seven metals have hardness -dependent equations. As a result, the NPDES
Permitting Unit will need site -specific effluent hardness data and instream hardness data, upstream of the discharge, for
each facility monitoring these metals in order to calculate permit limitations. Effluent hardness and instream hardness
sampling, upstream of the discharge, has been added to this permit at a monitoring frequency of quarterly. See Section
A. (1.) Effluent Limitations and Monitoring Requirements.
Concurrent with this notification, the Division will solicit public comment on this draft by publishing a notice in
newspapers having circulation in the general Caswell County area, as required by the NPDES Program. Please provide
your comments, if any, to me via email [[e-mail]] or write to my attention care of DEQ/ DWR / NPDES
Program no later than September 8, 2017. Your written comments are welcome but not mandatory.
Following the mandatory 30-day public comment period, the Division will review all pertinent comments on your permit
draft, and take appropriate action prior to issuing your final NPDES permit. If you have questions concerning this draft,
please e-mail me or call my direct line [phone].

Residuals Collection, Handling. Processing, Storage & Dismal
As requested by the Construction Grants and Loans Section of Division of Water Quality of
North Carolina Department of Environmental Quality (NCDEQ), collection, handling,
processing, storage and disposal of residuals generated in the product storage drum, oil water
separator (OWS), bag filter, aggregate filter, carbon vessels, ion exchange vessels, and backwash
filter are addressed in this plan.
Oil Water Separator and Product Storage Drum
Free product from the OWS discharges by gravity to a 65 gallon polyethylene product storage.
drum installed outside of the system building. The product storage drum is equipped with a high-
level switch to shut down operation of the remediation system. Residuals from. the OWS and
product storage drum are collected and handled by a contractor in accordance with all applicable
regulations on an as needed basis. ,After the collection of the residuals, the contractor
immediately hauls the residuals off the site. The contractor is also responsible for the proper
disposal or storagelprocessing of residuals.
Bag Filter
The bag filter is changed every month during scheduled monthly maintenance events. The used
bag filters are removed from the bag filter housing using disposable gloves and placed in a sealed
plastic container. The used bags are immediately shipped as a non -hazardous waste for proper
disposal. Pyramid is responsible for the collection, handling, and disposal of used bag filters.
Aggregate Filter and Carbon Vessels
The aggregate filter and carbon vessels are exchanged every six months by a contractor in
accordance with all applicable regulation. Used aggregate filter and carbon vessels are
immediately hauled off the site. The contractor is responsible for the residuals handling and
proper disposal or storagelprocessing.
Ion Exchange Vessels
Two ion exchange vessels were replaced with carbon vessels in May 2012. The NCDEQ
approved this change, however the number of carbon vessels has never been changed in the
current NPDES permit that expires on May 31, 2017. Please see the enclosed correspondence
between Pyramid and NCDEQ.
Backwash Filter -•
The used backwash filter media is collected and handled by a contractor in accordance with all
applicable regulations on an as needed. basis. Auer the collection of the used media, the
contractor immediately removes the filter media from the site for processing and/or disposal. The
contractor is also responsible for proper disposal or storagelprocessing of the used media.

Good morning Bob,
I have just received the referenced NPDES permit form our client and I've noticed that the Supplement to Permit Cover
Sheet (attached as a PDF file) contains an incorrect number of carbon vessels.
There should be four (4) carbon vessels listed on the sheet because two (2) Ion exchange vessels have been converted
to carbon vessels. Please see the forwarded emails.
Could you please email me the NPDES permit with the correct number of carbon vessels.
Thank you.
