NC0082767_Fact Sheet_20210503

FACT SHEET FOR EXPEDITED PERMIT RENEWALS
This form must be completed by Permit Writers for all expedited permits which do not require
full Fact Sheets. Expedited permits are generally simple 100% domestics (e.g., schools, mobile
home parks, etc) that can be administratively renewed with minor changes, but can include
facilities with more complex issues (Special Conditions, 303(d) listed water, toxicity testing,
instream monitoring, compliance concerns).

Section 1. Facility Overview:
The Spruce Pine WTP operates a conventional WTP designed for a potable flowrate of
1.61 MGD. The facility currently has no discharge (never has) to surface waters as it
routes all flow to the WWTP (NPDES Permit NC0021423). However, the facility has the
potential to discharge up to 110,000 gallons per day (1 filter backwashed each day for
20,000 gallons, plus 3 filters flushed 3 times per day with 10,000 gallons each time for a
total of 90,000 gallons). The Town chooses to keep this permit in case of an emergency
where they would need to discharge to the creek.
The facility utilizes chlorine gas for disinfection, alum/caustic for coagulation, caustic for
post pH adjustment, and orthopolyphosphate for corrosion control. Chemicals with the
potential to be discharged include alum/aluminum phosphate, fluoride, phosphate
polyortho caustic.
Per the previous fact sheet: Since its start up, the Town of Spruce Pine WTP diverts its
backwash wastewater to the local WWTP, and therefore does not discharge to Waters of
the State. A contract service operates this facility. The Permittee requests to maintain its
NPDES permit as backup in the event that surface discharge becomes preferable. As of
August 1, 2006, DWR waved the Permittee's requirement to submit DMRs until they
Page 1 of 9

may implement a surface discharge, therefore there are no effluent data to process for
renewal.
The Permittee operates a 1.6 MGD-capacity potable -water treatment plant (WTP)
utilizing conventional treatment technology (see permit for system components). After
treatment, wastewater as filtered backwash accumulates in a settling tank serving as "pre-
treatment" prior to connecting to the local WWTP.
In the event of discharge, prior to surface discharge, treated effluent would remain in the
settling tank for a time sufficient to settle solids. A treated and sampled effluent would
then decant to a gravity storm -sewer terminating at a culvert on Elm Street. This culvert
eventually empties into Beaver Creek. As needed, the Permittee would remove
accumulated solids in the settling tank and take them to the WWTP for permitted
processing.
Section 2. Compliance History:
• No NOVs/CPAs in the previous 5 years
• No toxicity results (no flow — facility is active)
Section 3. RPA:
There has been no flow in the previous 36 months. Therefore, it is not possible to run an
RPA.
Section 4. NCG590000 General Permit Eligibility:
• They use conventional technology, therefore they are eligible
• They do not discharge to HQW or ORW waters, therefore they are eligible
• They do not have any flow or parameter data so an RPA cannot be run to assess
limits for any parameters, therefore they are not eligible
• Conclusion: They are not eligible for the NCG59
Section 5. Changes from previous permit to draft:
• Updated eDMR footnote in A(1) and language in A(3)
• Updated outfall map
• Added facility grade in A(1)
• Updated language on the Supplement to Permit Cover Sheet
• Updated components list on Supplement to Permit Cover Sheet
• Added units of measure in A(1)
• Added monitoring for aluminum and fluoride in A(1) as the permit renewal
application indicates the possibility for discharge
Page 2 of 9

• Copper monitoring added in A(1) per 2009 WTP strategy (could not find
reasoning in previous fact sheets that it was ever monitored for or why removed)
• Added monitoring for TN and TP in A(1) as potential discharge is > 50,000 GPD
(per permittee correspondence)
• Updated flow monitoring to continuous/recording in A(1) as potential discharge is
> 50,000 GPD per 2009 WTP strategy
• Turbidity monitoring reduced to monthly in A(1) per 2012 WTP guidance
• Monitoring for manganese removed in A(1) as there is no longer a water quality
standard and per 2012 WTP guidance
• Added monitoring for total hardness and associated footnotes in A(1) per current
WTP guidance
• Monitoring for total iron removed in A(1) as there is no longer a WQS
• Updated TRC footnote in A(1)
• Updated turbidity footnote in A(1)
• Removed former footnote #4 in A(1) as sampling concurrent with toxicity is no
longer required per current WTP guidance
• Updated tox language in A(2)
Section 6. Changes from draft to final:
• None
Section 7. Comments received on draft permit:
• Linda Wiggs (ARO; via email 3/19/21): Unless something changes in the final
permit, I doubt ARO will have further comment on this one.
• Zach Thomas (ATB; via email 3/23/21): Everything looks good for Tox! I have a
note in our database that will keep them as not discharging until we receive
notification from them or CO.

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.
1. To perform a RPA on the Freshwater hardness -dependent metals the Permit
Writer compiles the following information:
Page 5 of 9

• Critical low flow of the receiving stream, 7Q10 (the spreadsheet
automatically calculates the 1Q10 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.
Page 6 of 9

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 + { [Kpo] [SSUU+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
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:
1 Q 10 = used in the equation to protect aquatic life from acute toxicity
Page 7 of 9

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:

I hope this works for you. I hand drew the schematic and listed the injection points. I also sent you a copy of the google
maps discharge I made to the actual discharge point at the creek. It starts at the waste tank at the plant and shows the
path it takes to the creek. It has elevations and gps points I shot listed on it. The max flow for the plant process is
1.61mgd or 370 gpm each filter. As for the question about max daily flow if we had to discharge I think 110,000 gallons
per day should cover it. We backwash one filter each day which is 20,000 gallons. We flush three filters three times per
day which is 10,000 gallons each time for a total of 90,000 gallons. If you need something else let me know. We have
never discharged to the creek.

Good morning Mr. Lankford,
I am reviewing the NPDES permit renewal application for the Spruce Pine WTP (NC0082767), and had some
questions. First, per part 15 of the renewal application, a flow schematic with flow volumes, points of chemical
addition, and all discharges routed to an outfall is required. This information was not provided with the renewal
application. In order for permit renewal review to continue, please provide this required schematic.
Additionally, I am aware that the WTP does not currently use it's NPDES outfall, but rather discharges to the sanitary
sewer system to the WWTP. It is unclear what the potential maximum daily discharge from the plant would be in the
event the WTP would need to discharge via the permitted NPDES outfall. This information is required in order to
continue permit renewal as well.
Please provide the two required items above as soon as possible to continue NPDES permit renewal review. If you have
any questions concerning this request, please feel free to reach out to me.
Thank you,
Brianna Young, MS
