'From permitted industrial flow of 1.403 MGD.
Briefly describe the proposed permitting action and facility background: The City of Shelby had applied
for an NPDES permit renewal for its First Broad River WWTP. The application was received by DWR on
February 5, 2018. The application was found largely complete, but missing the three PPAs, four 2nd species
toxicity test reports and the required Mercury Minimization Plan summary. The PPAs were submitted with
their corresponding DMRs in February 2014, May 2015, August 2016 as well as two more recent ones, in
Page 1 of 13

February 2018 and May 2019. The four 2nd species toxicity test reports were obtained from DWR Aquatic
Toxicity Branch, and represent samplings in February, May, August, and November 2017. The Permittee
sent a spreadsheet summarizing the progress of dental office review for its MMP on October 22, 2019.
Since the issuance of the current permit in 2013, several improvements have been made to the treatment
system under AtC Permit No. 024538A02, issued February 26, 2014. The Engineer's Certification for the
plant upgrade under the AtC permit, signed on April 15, 2016, was received by the Division. The process
flow description in the permit renewal application includes these changes. Therefore, the component list in
the Supplement to Permit Cover Sheet has been modified to include the system component changes.
This 6.0 MGD facility serves total a population of 22,880 residents comprising those in the City of Shelby
(21,000), Town of Fallston (1,200) and Town of Kingstown (680). The WWTP treats a combination of
domestic and industrial wastewater with a pretreatment program involving five significant industrial users
(SIUs), four of which are Categorical Industrial Users (CIUs). The SIUs include: Clearwater Paper
Corporation (CIU 430: Pulp, Paper and Paperboard), Dicey Mills, Inc. (closed operations; permit issued to
ensure proper closure of wastewater lagoon), Greenheck Fan Corp. (CIU 433: Metal Finisher), IMC Metals
America (CIU 468: Copper Forming), and KSM Castings USA, Inc. (CIU 464: Metal Molding and
Casting).
In addition, the WWTP receives remediated groundwater from FAS Controls, a former SIU (metal finisher).
The permit application documents seven pollutants from three recovery wells: 1,4-Dioxane, 1,1,1-
Trichloroethane, Trichloroethene, 1,1-Dichloroethene, 1,1-Dichloroethane, 1,2-Dichlorothane, and 1,1,2-
Trichloroethane. Pollutant concentrations from groundwater remediation effluent samples (i.e., entering the
City's sewer system via a manhole) collected in 2017 and 2018 are documented in the 2018 Groundwater
Remedial Action Progress Report submitted to NC Division of Waste Management (DWM) in August
2019.

The 2018 NC Integrated Report lists the receiving stream segment of First Broad River to be meeting
criteria for all parameters evaluated (metals, Benthos, DO, Fecal Coliform, Temperature, pH) with
exceptions of Iron (inconclusive), Fish Tissue Mercury, and Turbidity. The 2008 Broad River Basin Plan
cites streambank erosion as the most common source of turbidity. The plan recommends streambank
restoration to reduce erosion.

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/L 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 beproposedfor this permit
action: The current permit requires instream monitoring for Dissolved Oxygen (DO), Temperature and
Conductivity. In the current permit the upstream location is 100 ft upstream of the discharge, and the
downstream location is upstream of Beaverdam Creek. Instream data were submitted in eDMRs; available
data were reviewed for each above parameter.
Instream data for each parameter were charted and tested for up- and downstream differences of paired data
using paired two -sample t-test for means. Comparisons were also made with concurrent effluent data.
Instream parameters were evaluated against stream water quality standards where applicable.
Instream DO remains in the permit as a parameter of concern for aquatic life. Summer minima at both
stations were near the standard of 5.0 mg/L (15A NCAC 02B .0211) with one upstream minimum below it
at 4.9 mg/L (upstream range: 4.9-15.7 mg/L; downstream range: 5.2-15.5 mg/L). No statistically significant
differences were found between paired up- and downstream values on a given day (t = 1.0, p > 0.1).
Concurrent effluent DO data had similar minima but lower winter maxima (range was 5.3-9.7 mg/L). The
effluent does not appear to effect instream DO.
Instream Temperature remains in the permit as a parameter of concern for aquatic life. Summer maxima at
both stations were near the standard of 29°C for mountain and upper piedmont waters (15A NCAC 02B
.0211) with one upstream value of 30°C at 7/3/2017 and one downstream of 30°C at 7/11/2016 (both
instream temperature ranges were 1-30°C). Downstream temperatures tested higher than those upstream (t
= -10.7, p < 0.001) with an average up- to downstream increase of 0.7°C. Four occurrences of downstream
temperature increase greater than the standard 2.8°C increase standard for mountain and upper piedmont
waters (15A NCAC 02B .0211) have been reported (Table 2). Concurrent effluent temperatures differed in
having higher winter values (range: 12.3-28.5°C). Effluent temperatures may be affecting the instream
temperature; however, Stice Shoals Dam, located between the outfall and the downstream location may
also affect instream temperature.

Instream Conductivity remains in the permit due to facility's receiving wastewater from industrial users.
Review of instream conductivity showed similar ranges between the two sites (upstream: 30-114
µmhos/cm; downstream: 31-114 µmhos/cm). Average conductivity was higher downstream at 70 vs. 58
µhmos/cm upstream, and statistically significant increases from upstream to downstream on a given day
were found (t =-23.98, p < 0.0001), suggesting an effect by the effluent. There are no effluent data to
Page 4 of 13

compare against, as Conductivity monitoring is not in the permit. To better understand the facility's impact
on instream conductivity, effluent Conductivity monitoring has been added to the permit.
NC DWR permitting guidance states that instream monitoring for Fecal Coliform is not required unless the
receiving water is impaired due to coliform or is a Class B waterbody. The receiving stream is a Class C
water and is not listed in as impaired due to coliform in the NC Final 2018 303(d) list. The current permit
does not have instream Fecal Coliform monitoring; this parameter is not required and was not added to the
permit.
Is this facility a member of a Monitoring Coalition with waived instream monitoring (YIN): NO.
Name of Monitoring Coalition: N/A
5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): From September 2014 through
August 2019, two violations resulted in compliance actions: 1) a Fecal Coliform value of 1,393 cfu/100 mL
on 11/14/2015, resulting in an issuance of a Notice of Violation (NOV) for weekly geometric mean
exceedence; and 2) a pH value of 5.7 SU, resulting in an issuance of a Notice of Deficiency (NOD) for not
reaching the daily minimum. Several other violations were reported in this time period, but were not acted
upon based on Best Professional Judgement (BPJ).
Summarize the compliance record with aquatic toxicity test limits and any second species test results (past
5 years): The facility passed 20 of 21 quarterly chronic toxicity tests from February 2015 through June
2019. All four 2" d species toxicity tests, sampled in February, May, August and November 2017, also
passed.
Summarize the results from the most recent compliance inspection: The most recent facility inspection,
conducted on 11/29/2017, reported that the facility was clean and neat in appearance, and records were up
to date. The most recent pretreatment compliance inspection, conducted on 05/01/2019, reported the
POTW's industrial pretreatment program to be properly implemented. No compliance issues were noted in
either inspection report.
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); 7Q10 streamflow (chronic Aquatic
Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, W.
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.
Ox en -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/L for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
Page.5 of 13

If permit limits are more stringent than TBELs, describe how limits were developed: The current BOD
limits are based on results of a Level B model run in 1992 for speculative limits. The limits were developed
in response to the proposed expansion of the Shelby WTP, located 6.9 river miles upstream of the WWTP
discharge, which reduced the receiving stream's summer 7Q 10 from 70 cfs to 44.3 cfs. The WTP expansion
was completed in 1996, triggering the current limits to become effective.
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/L (summer) and 1.8 mg/L (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 µg/L) and capped at 28 µg/L (acute impacts). Due to analytical issues, all TRC values
reported below 50 µg/L are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: Ammonia was
assessed for toxicity in the attached Wasteload Allocation (WLA) sheet using the flow design of 6.0 MGD,
and receiving stream low flows of summer 7Q10 = 44.3 cfs and winter 7Q10 = 112 cfs. The resulting
allowable summer concentrations were the same as the summer limits in the current permit (which became
effective August 1, 2016, after plant upgrade completion). The resulting allowable winter concentrations
were less stringent than the winter limits in the current permit (developed in 1992 based on Level B model
results for DO protection). Therefore, the current Ammonia limits have been maintained in the permit.
The current TRC limit of 28 µg/L was first established in the permit in 2004 as capped to protect against
acute impacts in the receiving water per the then new TRC policy. WLA calculations for TRC also cap the
allowable concentration at 28 µg/L. The current TRC limit has been maintained in the permit.
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 % 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 from August 2016
through August 2019. 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: Cyanide.
• 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: Copper, Silver.
o Silver data were all nondetects at < 1 and < 5 µg/L, with the latter intermittently within the
past year. In accordance with Division guidance on dissolved metals (DWR 2016),
Page 6 of 13

quarterly monitoring has been added to the permit, to be reported to the lower reporting
level.
• No Limit or Monitories: 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: Arsenic,
Beryllium, Cadmium, Total Phenols, Total Chromium, Lead, Molybdenum, Nickel, Selenium,
Zinc.
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern.
o The following parameter(s) will receive a water quality -based effluent limit (WQBEL)
with monitoring, since as part of a limited data set, two samples exceeded the allowable
discharge concentration: None.
o The following parameter(s) will receive a monitor -only requirement, since as part of a
limited data set, one sample exceeded the allowable discharge concentration: None.
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: This facility is a Major POTW, and a chronic WET limit at
17% effluent will continue on a quarterly frequency. The WET limit is based on the Instream Waste
Concentration (IWC) as calculated from the design flow of 6.0 MGD and the receiving stream 7Q10 of
44.3 cfs (WET Permitting Limits and Monitoring Requirements guidance memo, 8/2/1999).
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/L) 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/L) and/or if any individual value exceeds a TBEL value of 47 ng/L.
Describe proposed permit actions based on mercury evaluation: A mercury minimization plan (MMP)
special condition was added to the permit in 2013. As an MMP summary, the Permittee submitted a
spreadsheet of dental office contacts for amalgam review upon request on October 22, 2019. Submitted low
level mercury data from November 2016 through August 2019 were reviewed for TMDL evaluation.
Sample results ranged 0.77-2.33 ng/L with no annual averages exceeding the TBEL of 47 ng/L and no
individual values exceeding the WQBEL of 69.16 ng/L (Table 2). Because of the low values reported, the
MMP special condition has been removed from the permit.

Other TMDL/Nutrient 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: The emerging compound
1,4-Dioxane was reported to be present in concentrations "ND-500 µg/L" in FAS Controls remediated
groundwater received by the WWTP from three recovery wells in the permit application. Recovery well
data sampled in 2017-2018 ranged from 22.5-55.7 µg/L per the 2018 Groundwater Remedial Action
Progress Report for the FAS Controls site submitted to NC DWM in accordance with 15A NCAC
13C.0306(o). The report also documents effluent data taken from the discharge point (i.e., to the City's
sewer system via a manhole) from the same sampling events, with results averaging 36.5 µg/L (range: 28.3-
45.1 µg/L, n = 7 samples). Based on the average concentration and a discharge of 2,000 gpd as
communicated by John Reuscher, who had prepared the annual report for the groundwater remediation site,
1,4-Dioxane loading to the WWTP is 0.0006 lb/day (Eqn 1).
0.0006 lb/day 1,4-Dioxane Load = 0.0365 mg/L X 8.34 X 0.002 MGD (Eqn 1)
With an average WWTP discharge flow of 3.5 MGD for CY2018 from DMR data, this load translates to
an Outfall concentration of 0.021 µg/L (Eqn 2).
0.021 µg/L effluent 1,4-Dioxane = [0.0006 lb/day / (8.34 X 3.5 MGD)] X 1000 (Eqn 2)
To verify that effluent concentrations are below the NC human health instream criterion of 80 µg/L for
Class C waters, a quarterly monitoring requirement for 1,4-Dioxane was added to the draft permit. During
the public comment period, the Permittee requested monitoring of 1,4-Dioxane be reduced from quarterly
to annual via the Effluent Pollutant Scan, providing quarterly 1,4-Dioxane concentration data and flow data
sent to the plant from the groundwater discharge. from March 2018 through September 2019. Through mass
loading calculations, estimated WWTP effluent concentrations ranged from 0.005-0.018 µg/L, well below
the 80 µg/L instream criterion. Based on these results, 1,4-Dioxane quarterly monitoring has been removed
from the draft permit; and it was added to the parameter list in the Effluent Pollutant Scan special condition.
The permit application also listed the following VOCs as received from FAS Controls: 1,1,1-
Trichloroethane, Trichloroethene, 1, 1 -Dichloroethene, 1, 1 -Dichloroethane, 1,2-Dichlorothane, and 1,1,2-
Trichloroethane. These pollutants also are reported in the groundwater remediation report, discharged in
concentrations ranging from 1.7-421 µg/L. None of these pollutants were detected in the three effluent
pollutant scans. Therefore, monitoring requirements were not added to the permit for any of these VOCs.
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.
Page 8 of 13

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 2007 Memo: 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)
Municipals (if not applicable. delete and skip to Industrials)
Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/L
BOD51TSS for Monthly Average, and 45 mg/L for BODs/TSS for Weekly Average). YES.
If NO, provide a justification for alternative limitations (e.g., waste stabilization pond). NA.
Are 85% removal requirements for BOD51TSS included in the permit? YES.
If NO, provide a justification (e.g., waste stabilization pond). 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): NO.
If YES, confirm that antibacksliding provisions are not violated: NA.
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
Page 9 of 13

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.
Monitoring frequencies follow 15A NCAC 2B .0500 for all parameters.
For instream monitoring, refer to Section 4.
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: 11/05/2019
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
Page 11 of 13

within the 30 days comment period indicating the interest of the party filing such request and the reasons
why a hearing is warranted.
14. NPDES Division Contact:
If you have questions regarding any of the above information or on the attached permit, please contact Gary
Perlmutter at [phone] or via email at gM.perlmutterAnedenr.zov
15. Fact Sheet Addendum (if applicable):
Were there any changes made since the Draft Permit was public noticed (Yes/No): YES. Only the City of
Shelby (Permittee) provided comments; see specifics below.
If Yes, list changes and their basis below:
• The system component list in the Supplement to Permit Cover Sheet was modified based on recent
equipment upgrades.
• A second system component list was added in the Supplement to Permit Cover Sheet for future
equipment changes, planned to be operational in late 2020.
• The Permittee requested that the proposed quarterly monitoring for Silver be removed from the
permit, deferring to the plant's pretreatment Long Term Monitoring Plan (LTMP). Quarterly Silver
monitoring was retained in the permit based on Division guidance on dissolved metals standards
(DWR 2016).
• The MMP special condition has been removed from the permit as the Permittee requested in light
of the effluent mercury sample results were all at very low levels, ranging from 0.77-2.33 ng/L.
• Quarterly monitoring of 1,4-Dioxane had been removed from the permit and placed instead as a
parameter in the Effluent Pollutant Scan per the City's request. The City provided quarterly
concentration and flow data sent to the plant from Honeywell International (i.e., FAS Controls)
remediated groundwater discharge, from March 2018 through September 2019. Through mass
loading calculations, estimated WWTP effluent concentrations ranged from 0.005-0.018 µg/L, well
below the 80 µg/L criterion for Class C waters.
16. Fact Sheet Attachments (if applicable):
• Three Annual Monitoring and Pollutant Scan reports
• Four Effluent Toxicity Report Form -Chronic Fathead Minnow Multi -Concentration Test
• E-mail from Permittee with dental office review spreadsheet as MMP summary
• PERCS Information Request form
• FAS Controls 2018 Groundwater Remedial Action Progress Report, pp. 14-15 plus "Summary of

You called about two items with the City of Shelby permit renewal NC0024538:
1. Whether Dioxane testing was completed at the WWTP. NO
2. Update on Dental Amalgam: The City of Shelby is following the "Three R plan" (receive, review, retain). The
reports have been mailed to the local dental offices. We are currently following up with some who have not
returned the reports and one who did not fill all the information in.
Please let us know if you need additional information.

gallons with an average extraction rate of approximately 0.23 gpm; and
• The RW-3 screen begins at 15 feet below the top of bedrock. Based on meter readings,
the total groundwater extracted from RW-3 in 2018 was 12,854 gallons with an average
extraction rate of approximately 0.024 gpm.
Within the piedmont, PWR typically is the most hydraulically conductive portion of the aquifer
with limited flow sourced from the bedrock which is dependent upon the frequency of water
bearing fractures. RW-1 and RW-2 produce the most groundwater and likely source
groundwater from the PWR interval and several water bearing fractures that were noted during
drilling. RW-3 is screened 15 feet below the top of competent bedrock and can extract the least
which is expected since the PWR is not saturated at this location and due to the limited number
of fractures encountered during drilling.
Total VOCs and 1,4-DXA over time in groundwater from the extraction wells and nearby
monitoring wells MW-10, MW-26B, and DW-07B are shown in Appendix D. These graphs
show decreasing concentrations of total VOCs (degradation products and parent compounds) and
1,4-DXA in groundwater from the extraction wells and nearby monitoring wells over time, with
the exception of extraction well RW-3 which shows generally stable concentrations:
Concentrations detected in the effluent sample (EFF) collected at the City of Shelby discharge
point showed elevated concentrations of total VOCs and 1,4-DXA following system startup,
however, concentrations have since declined and are relatively consistent. As indicated by the
updated predictive modeling results provided in the 2017 Groundwater Remedial Action
Progress Report, the focused groundwater extraction system is capturing the majority of the
impacted groundwater flow in this area. Overall, shallow groundwater at this area of the site
(MW-10) remains below 2L standards and contaminant concentrations in the groundwater
samples collected from the nearby bedrock monitoring wells (DW-07B and MW-26B) are
decreasing over time indicating adequate capture.

upgradient PZ-4. There is some variation of the temperature response at PZ-5, TPZ-5
and TPZ-6 and indicates some effect of fresh recharge with the TreeWell units.
Groundwater elevation responses to rainfall are more pronounced within TPZ-5 and TPZ-
6 compared to PZ-5.
• PZ-6 Cluster: Includes PZ-6 (screened in PWR outside of the TreeWell units) and TPZ-7
and TPZ-9 (screened inside of TreeWell units). The temperature response following rain
events is muted at TPZ-7 and TPZ-9 compared to PZ-6. This indicates the groundwater
entering the base of the TreeWell units is not sourced from fresh recharge but rather
sourced from groundwater in the PWR. Groundwater elevation responses to rainfall
indicate a higher response in TPZ-7 and TPZ-9 compared to PZ-6.
Increased flow and an elevated stage within Hickory Creek following rain events result in a
creek stage higher than the water table near the creek. This causes what is called bank storage
which is the temporary storage of creek water within the water table aquifer. Groundwater VOC
and 1,4-DXA concentrations may be slightly diluted while the bank storage within the water
table drains. This is observed at the TPZ-5, TPZ-6, TPZ-7 and TPZ-8 locations during larger
rainfall events (as evidenced by the higher groundwater elevation response compared to the
neighboring piezometers located outside of the TreeWell units) and is likely exacerbated by the
connection between the TreeWell unit which was installed with a 42-inch diameter borehole and
the PWR zone which has a higher relative permeability than the overlying saprolite.
3.1.2 Focused Groundwater Extraction System Evaluation
The focused groundwater extraction system is comprised of RW-1, RW-2, and RW-3. The
extraction wells were constructed as follows:
• RW-1 is screened across the PWR and the fractured bedrock. Based on meter readings,
the total groundwater extracted from RW-1 in 2018 was 189,892 gallons with an average
extraction rate of approximately 0.36 gallons per minute (gpm);
• The RW-2 screen begins at the top of the fractured bedrock (i.e. bottom of PWR). Based
on meter readings, the total groundwater extracted from RW-2 in 2018 was 118,990

FIRST BROAD RIVER
WATERSHED
HUC's 0305010507 Et parts of 0305010506
Includes Knob Creek, Brushy Creek, Hickory Creek Et Beaverdam Creek
GENERAL WATERSHIED DESCRIPTION
The First Broad River and its tributaries originate in Rutherford County (the First
Broad River headwaters), flow through Cleveland County and join the Broad River
just above the North Carolina -South Carolina state line. Tributaries in the First Broad
River watershed include Knob Creek, Brushy Creek, Beaverdam Creek and Hickory
Creek (Figure 5-2). Land cover is predominantly forested with agriculture, residential
and commercials areas (Figure 5-1). Streams exhibit both mountain and piedmont
characteristics due to their location within the basin; and geology, soils and streamflows
vary.
WATER QUALITY OVERVIEW
Of the 151 stream miles in the First Broad River watershed, 76.2 were monitored by
DWQ. Of these monitored waters, 78 percent are Impaired, 19 percent are Supporting
and 3 percent are not rated for aquatic life. The majority of impairments and impacts
are associated with fecal coliform bacteria, habitat degradation, turbidity and nutrient
impacts.
Biological monitoring was conducted at nine basinwide sites. Two benthic sites
improved (Brushy and Beaverdam Creeks), and biologists noted that the improvements

are likely the result of higher flows in 2005 versus those measured in 2000 (97 cubic
feet per second (cfs) compared to 49 cfs). In those watersheds primarily influenced
by point source pollution (such as Brushy and Beaverdam Creeks), increased streamflow can dilute point source discharge
and result in short-term improvements to aquatic communities. In

protected watersheds (such as in the First Broad River headwaters),
increased streamflow can improve instream physical conditions
(i.e., increase availability of wet habitat and increased dissolved
oxygen levels), which often results in more favorable conditions
for macroinvertebrate colonization. Two ambient stations are also
located in this watershed.

Even though the aquatic communities are supporting throughout the 01
watershed, a section of the First Broad River is impaired in the aquatic
life category due to a water quality standard violation for turbidity. In o
addition, the First Broad River is Not Rated in the recreation category, 0
and two streams are identified as streams with noted impacts (Table
5-1).
There are five minor and three major NPDES Discharge Permits within
this watershed. Two of these facilities obtained compliance violations
between 2002 and 2006.

How to Read this Document
This document was written to correspond with our new Geographic Online Document Distribution (OGDD)
tool using Google Earth. If you are unable to use Google Earth, this document provides maps and associated
water quality information and a discussion of water quality trends occurring in the watershed. Google Earth is
an independent software program which can be downloaded to a personal, business, and most local and state
government computers; the program allows you to view satellite imagery of the earth's surface along with location
identifiers. DWQs Basinwide Planning Unit created a "transparency" add on layer to Google Earth with basinwide
water quality data, which allows a user to locate their watershed, pinpoint a waterbody and use support ratings,
find a location of a permit and provides links to PDF watershed reports, For more information on how to download
Google Earth and DWQ's data visit DWQ's Basinwide Planning's OGDD website. Please contact Melanie Williams
for more information at [e-mail] or 919-807-6447.
Impaired streams are those streams not meeting their associated water quality standards in more than 10 percent
of the samples taken within the assessment period (January 1, 2002 through December 31., 2006) and impacted
streams are those not meeting water quality standards in 7 to 10 percent of the samples. The Use Support report
provides information on how and why water quality ratings are determined and DWQ's "Redbook" describes
in detail water quality standards for each waterbody classification. For a general discussion of water quality
parameters, potential issues, and rules please see "Supplemental Guide to North Carolina's Basinwide Planning:
Support Document for Basinwide Water Quality Plans".
Appendix 5-A provides descriptions of Use Support ratings for all monitored waterbodies in the subbasin.
Appendix 5-B provides a summary of each ambient data monitoring station.
Appendix 5-C provides summaries of biological and fish assessment monitoring sites.

AU#: 9-50-(19.5) 9-50-(28)
Two benthic sites (AB19 and AB20) and one ambient monitoring station (AA6) are located on the First Broad River in
Cleveland County. Site AB19 received a Good bioclassification. The substrate was slightly embedded with a mix of
bedrock (30 percent), rubble (10 percent), gravel (10 percent), sand (20 percent) and silt (20 percent). Habitat was
good (habitat score 80); however, DWQ biologists noted eroding streambanks within the sampling reach. The site has
5.3

been sampled twice before (1995 and 2000), resulting in a Good bioclassification each time. The abundant presence of
three pollution intolerant species and long-lived stoneflies suggests stable and favorable water quality conditions in this
section of the river.
Sites AB20 and AA6 are the most downstream sites on the First Broad River; consequently, habitat and water quality is
impacted by upstream water and land use. Site AB20 has been sampled seven times since 1983 resulting in a mix of
Good -Fair and Fair bioclassifications. In 2005, the site received a Good bioclassification and several pollution intolerant
species were collected for the first time. Substrate is mostly sand (80 percent) with some gravel (10 percent) and silt (10
cpercent). Primary habitat problems include eroding streambanks, frequent breaks in the riparian zone, and inadequate
N instream habitat.
Despite the Good bioclassification at site AB20, ambient monitoring at site AA6 shows that the water quality standard
for turbidity (>50 NTU) was exceeded in 15.5 percent of the samples collected from January 2002 through December
2006. Therefore, this section of the First Broad River is impaired for aquatic life due to exceedences in the water quality
standard. This section of the First Broad River is also Not Rated in the recreation category due to high levels of fecal
coliform bacteria. Nearly 26 percent of the samples collected exceeded 400 colonies of fecal coliform bacteria/100
milliliters (ml) of water. Current methodology requires additional bacteriological sampling for streams with a geometric
mean greater than 200 colonies/100 ml or when concentrations exceed 400 colonies/100 ml in more than 20 percent
of the samples. These additional assessments are prioritized such that, as monitoring resources become available, the
highest priority is given to those streams where the likelihood of full -body contact recreation is greatest. No portion of
the First Broad River is classified for primary recreation (Class B); therefore, it was not prioritized for additional sampling
during this assessment period. Potential sources of elevated bacteria levels include failing septic systems, straight pipes
and nonpoint source runoff from pasture and forestlands.
c Recommendations: Restoration is needed to stabilize streambanks and reduce erosion. Installation of fencing along this
c segment with animal operations will prevent farm animals from eroding streambanks and depositing harmful bacteria
H and excess nutrients into the surface water. The Town of Shelby should implement a Sediment and Erosion Control Local
Zj Program to help control construction site sediment from entering surface waters. More information on local programs
can be found on the Division of Land Resources web site.

> E E K AU#: 9-50-19-(2.5), 9-50-19-(4)
M Knob Creek is located in north -central Cleveland County, where land use consists of agriculture, forest and some residential
o development. Site AF13 received a Good -Fair bioclassification. In 2005, the number of fish and the percentage of species
mL with multiple age classes was less than those collected in 2000. The bluehead chub (a nutrient indicator species) was the
L dominant species. DWQ biologists noted that the change in the number and percentage of species was likely impacted
by drought (2000) and subsequent high flow conditions experienced during the 2004 hurricane season.
JLocated approximately 2.5 miles downstream of site AF13, site AB32 received a Good bioclassification. Substrate is
a- mostly sand (90 percent) with only a small amount of gravel (10 percent). Biologists noted several habitat problems,
z including severe streambank erosion, frequent breaks in the riparian zone and inadequate instream habitat (habitat score
a 50). Even though Knob Creek has received a Good bioclassification in 1995, 2000 and 2005, the most recent sampling in
°0 2005 shows that the diversity of species is declining. Loss of diversity is often an indication of nonpoint source impacts
and changes in habitat.

a
BRUSHY CREEK AU#: 9-50-29
mBrushy Creek is located in west -central Cleveland County. Fish (AF14 and AF9) and benthic (AB8) samples were collected
in lower Brushy Creek. Site AF14 received a Good -Fair bioclassification. In 2005, eighteen species were collected with
d the bluehead chub (a nutrient indicator species) being the dominant species. DWQ biologists noted that the diversity of
cdarters, sunfish, bass and trout were lower than expected.
V
Z Fish were also collected at site AF9 in 2004. This site is located 4.1 miles downstream of site AF14 and was selected as
part of a fish community urbanization study by NC State University (unpublished data). Unlike site AF14, site AF9 rated
Excellent. The difference in the ratings was due to the collection of sunfish, bass and trout. Differences were also found
in the trophic structure and more species with multiple age groups were identified. The instream habitat, pools and
canopy were of greater quality than that found upstream, and the bluehead chub constituted only 24 percent of total
number of species downstream compared to 54 percent of the species upstream.
Site AB8 was co -located with siteAF9 and received an Excellent bioclassification. Substrate was a mix of slightly embedded
5.4

rubble (10 percent), gravel (10 percent), sand (70 percent) and silt (10 percent). Primary habitat problems included poor
instream habitat and moderate streambank erosion (habitat score 66). Despite the habitat problems, several pollution
intolerant species were collected for the first time in 2005 and conductivity was much lower, suggesting water quality
improvements.
HICKORY CREEK AU#: 9-50-30
Hickory Creek drains the eastern half of the Town of Shelby in south-central Cleveland County. Previous assessments
describe the creek as "...generally typical of the basin - sandy substrate, shallow runs, infrequent and small side pools, n
shallow gravelly riffles." Despite the marginal instream habitat, the riparian zone is wide and intact. Site AF11 received o
a Good bioclassification. Twenty-four species were collected from the site. The bluehead chub (a nutrient indicator
species) and the greenfin shiner were the two dominant species. Trash, including automotive tires and aluminum cans,
continue to be an issue in the stream and BMPs are recommended to control sedimentation.
BEAVERDAM CREEK AU#:9-50-32
Beaverdam Creek drains southwestern Cleveland County. Land use is a mix of forest, agriculture, commercial and
residential properties located along the US 74 corridor. Benthic (AB2) and fish (AF10) samples were collected in lower
Beaverdam Creek. Site AB2 received an Excellent bioclassification for the first time in 2005. Even though the substrate
was an uneven mix of sand (60 percent), gravel (30 percent) and rubble (10 percent), there were several pollution
intolerant species present. Increased streamflows likely diluted impacts from the wastewater and stormwater outfalls
upstream of the sampling site, and two facilities (Crest High School and Middle School) no longer discharge to Beaverdam
Creek.
Site AF10 received a Good fish bioclassification. Twenty-three species were identified; however, the abundance of the
bluehead chub (40 percent) and the elevated percentage of omnivore -herbivore species indicate nutrient enrichment
from nonpoint sources of pollution. The number of intolerant species has also declined over time and instream habitat
did not support predatory fish species.
Site AA7 is located in Sugar Branch, which is a tributary to Beaverdam Creek. Thirty-five percent of the samples collected
exceeded 400 colonies of fecal coliform bacteria/100 milliliters (ml) of water. Current methodology requires additional
bacteriological sampling for streams with a geometric mean greater than 200 colonies/100 ml or when concentrations
exceed 400 colonies/100 ml in more than 20 percent of the samples. These additional assessments are prioritized such
that, as monitoring resource become available, the highest priority is given to those streams where the likelihood of
full -body contact recreation is greatest. No streams in the Beaverdam Creek sub -watershed are classified for primary
recreation (Class B); therefore, Sugar Branch was not prioritized for additional sampling during this assessment period.
Potential sources of elevated bacteria levels include failing septic systems, straight pipes and nonpoint source runoff
from pasture and forestlands. Sugar Branch is Not Rated for recreation. Although not a water quality standard violation,
pH is also a noted concern in Sugar Branch. The pH was below the water quality standard of 6.0 in nearly nine percent
of the samples collected.
Recommendations for this watershed can be found later in the chapter.
SIGNIFICANT NON-COMPLIANCE ISSUES
There are eight NPDES WWTP permitted in the First Broad River watershed. No significant non-compliance issues were
identified for the majority of facilities; however, monitoring and/or operating violations have been issued to a few. Two
such facilities are located in the Brushy Creek watershed and include PPG\Industries (Permit NC0004685) and Ramseur
Washerette (Permit NC0030481). PPG is. a major industrial process and commercial wastewater facility with a permitted
flow of 1.3 million gallons per day (MGD). In August 2002, PPG started a pilot project where up to 100 percent of their
discharge was recovered, filtered and used in the non -contact cooling process. As a result, there has been a significant
reduction in the volume of water discharged into Brushy Creek. The facility was last inspected in September 2006 and is
in full compliance with its permit limits.
Ramseur Washerette is a minor industrial process and commercial wastewater facility with a permitted flow of 0.0056
MGD. The facility mostly treats wash water from washing machines and two one -stall bathrooms. Ramseur Washerette
was last inspected in MAy 2005 when several violations were noted and included problems related to operations and
maintenance, disinfection, lagoons and record keeping. Based on the most recent inspection, the owners were hoping
to tie into sewer lines that were being laid throughout the area; however, the line was never laid to the facility. The
N
c
5.5

facility is identified as non -compliant and the owners are considering closing the facility. If the facility is closed, it is
recommended that the permit be rescinded provided that the bathroom facilities are hooked onto a different treatment
system (i.e., septic system).
LOCAL INITIATIVES
NC AGRICULTURE COAST SHARE PROGRAM
0o
o The NC Agriculture Cost Share Program (NCACSP) was
established in 1984 to help reduce agricultural nonpoint
c runoff into waters of the state. The program helps
c
owners and renters of established agricultural operations
improve their on -farm management by using approved
Ln agricultural BMPs. BMPs include vegetative, structural
c or management systems that can improve the efficiency
0 of farming operations while reducing the potential for
o surface and groundwater contamination. The NCACSP is
0 implemented by the Division of Soil and Water (DSWC),
M which divides the approved BMPs into five main purposes
CL
em or categories:
• Erosion Reduction/Nutrient Loss Reduction in Fields
• Sediment/Nutrient Delivery Reduction from Fields
• Stream Protection from Animals
• Proper Animal Waste Management
• Agricultural Chemical (agrichemical) Pollution

The NCACSP is a voluntary program that reimburses farmers up to 75 percent of the cost of installing an approved
BMP. The cost share funds are paid to the farmer once the planned BMP is completed, inspected and certified to be in
accordance with NCACSP standards. The annual statewide budget for BMP cost sharing is approximately $6.9 million.
During this assessment period, $170,702 was allocated for BMPs in the First Broad River watershed. Table 5-2 summaries
the cost and total BMPs implemented.
RECOMMENDATIONS
Habitat Degradation
In most cases habitat is degraded be the cumulative effect of several stressors acting in concert. These stressors often
originate in the upland portions of the watershed and may include impervious surfaces, sedimentation and erosion from
construction, general agriculter, and other land disturbing activities.
m Many tools are available to address habitat degradation including:
w urban stormwater BMPs; agricultural BMPs; ordinance and/or
rule changes at the local, state, and federal level; volunteer s

^Turbidity
Turbidity is a measure of cloudiness in water and is often
accompanied with excessive sediment deposits in the streambed. Improve
Excessive sediments deposited on stream and lake bottoms can choke Plan
spawning beds (reducing fish survival and growth rates), impair fish food
sources, fill in pools (reducing cover from prey and high temperature refuges),
Plan
5.6

and reduce habitat complexity in stream channels. Excessive suspended sediments can make it more difficult for fish
to find prey and at high levels can cause direct physical harm, such as clogged gills. Sediments can cause taste and
odor problems, block water supply intakes, foul water treatment systems, and fill reservoirs (USEPA, 1999 and Waters,
1995).
Soil erosion is the most common source of turbidity and sedimentation and while some erosion is a natural phenomenon,
human land use practices accelerate the process to unhealthy levels. Construction sites, mining operations, agricultural
operations, logging operations, excessive stormwater flow off impervious surfaces are all potential sources. The distribution
of turbidity violations and sample locations make it difficult to isolate a single source of erosion in this watershed. It
n
appears, however, violations are highest near agricultural areas, and transitional suburban areas. Violations are lowest
v
in the upper watershed where land cover is predominantly forest. This trend demonstrates the importance of protecting
and conserving stream buffers and natural areas. Information about starting a Sediment and Erosion Control Local
Program can be found on the Division of Land Quality's web page.

O
Fecal Coliform Bacteria
o
The fecal coliform standard for freshwater is 200 colonies per 100 milliliters (ml) of water based on at least five consecutive
X
samples taken during a 30-day period, not to exceed 400 colonies per 100 ml in more than 20 percent of the samples
rn
during the same period. There are no waters Impaired for fecal coliform bacteria in the First Broad River watershed.
X
However, fecal coliform bacteria concentrations were above the 400 colonies/100 milliliter (mL) water quality guideline
in more than 20 % of at least one ambient monitoring stations in this watershed.
zLA
The presence of fecal coliform bacteria in the aquatic environment indicates that the water has been contaminated from
v
D
the fecal material of humans or other warm-blooded animals. Elevated fecal coliform bacteria numbers can indicate
z
contamination by harmful pathogens or disease causing bacteria or viruses that also exists in fecal material. Livestock
-*r
and family pets are large contributors to this problem. As seen in Table 2-1, the Agriculture Cost Share Program has
installed over 700 linear feet of fencing along streams to help keep livestock out of the streams. This will significantly
decrease the amount of fecal coliform bacteria contaminating the streams. Many municipalities have been placing pet
c
waste bag and trash bins in public parks and along green ways to encourage and educate the public on the importance of
of
a
keeping the waste out of the streams.
X
Nutrient Impact
Nutrients refer to phosphorus (P) and nitrogen (N), which are common components of fertilizers, animal and human
a
c
waste, vegetation, aquaculture and some industrial processes. Nutrients in surface waters come from both point and
nonpoint sources including agriculture and urban runoff, wastewater treatment plants, forestry activities and atmospheric
deposition. While nutrients are beneficial to aquatic life in small amounts, excessive levels can stimulate algal blooms
c
and plant growth, depleting dissolved oxygen in the water column.
O
Nutrient impacts in this watershed are mainly from agriculture, commercial and residential property stormwater runoff.
Ln
Riparian buffers are needed along streams to filter excess nutrients and other contaminates before the runoff reaches
O
the stream. Excessive fertilizing of residential lawns and golf courses also significantly impacts water quality. Education,
9P
along with encouraging the use of riparian buffers, can reduce the amount of phosphorus and nitrogen entering surface
a
waters.

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.

3. 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
2B.0200 (e.g., arsenic at I0.µg/1 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 Anah sis (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.
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.

Permit No. NCO024538
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) + f 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 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:
Cdiss — 1 1 ff i
Ctotal 1 + { [Kp.] [ss(1+ai] [10-6] i
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) (Cwgs) — WOW) (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. NCO024538
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 Vl.
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:
Parameter ! Value Comments (Data Source)

Subject: [External] RE: FAS Controls effluent location
Gary:
The sample we have designated as "Effluent' is the combined flow of our groundwater recovery wells into the sewer
manhole located on the subject property. The City of Shelby WWTP is located approximately 7 miles south of the
subject property.
We have four recovery wells as part of our extraction system : RW-1 through RW-4. Last month the discharge to the
sewer was approximately 2,000 gallons per day.
Please let me know if you have any other questions or need further data/clarifications.
Thanks and regards.

Subject: FAS Controls effluent location
Dear Mr. Reuscher,
I left a voicemail and am following up here. I am working on the NPDES permit renewal for the City of Shelby WWTP and
have learned that they receive remediated groundwater from the FAS Controls Inc. (former Honeywell) site, for which
you have prepared annual reports to the Division of Waste Management. In these reports I see that samples have been
collected of the effluent, but need to know if they represent effluent entering the sewer system or discharged from the
WWTP, as the reports are unclear. Also, I understand that the flow to the sewer system is about 3 gpd (—I gpd from each
of the three recovery wells) — is that correct?
Thank you for your help,

REM DRAFT NPDES PERMIT NCO024538 Comments
City of Shelby, NC
Dear Mr. Perlmutter:
By the end of 2020 the City of Shelby will have invested well over $35.0 Million in upgrades to
the First Broad WWTP. These upgrades were required by NCDEQ's implementation of more
stringent limits which became effective in 2016 ($10.5M), additional influent/headworks
upgrades in 2018 ($6.6M) and currently replacement of our Biosolids Handling facility ($18M)
which is scheduled to be completed in late 2020.
Based upon previous upgrades the equipment list for the First Broad WWTP should be:
• Course manual and two fine rotary mechanical screens
Grit Removal System
• Main Lift Liftstation with four centrifugal pumps
• External Powerhouse for Influent;
• Primary Splitter Box;
• Two (2) primary clarifiers
s Raw Sludge Pump Station
P. Three Aeration Basins, each with
o One (1) Anoxic Section with three cells each.
o Four (4) Oxic Zones
• Four (4) Secondary Clarifiers
• WAS Pump Station
One (1) Gravity Sludge Thickener
• One (1) Gravity Sludge Pump Building
• One (1) two -compartment contact for chlorine disinfection and sulfur dioxide for
dechlorination

• Sludge Holding Tank
• Two (2) belt filter presses
• Ten (10) bay sludge compost building
• 2000KW Stand-by Generator (Whole Plant) and 800KW Generator (Influent Only)
The City will be bringing on new equipment with the construction of the new biosolids handling
facility in late 2020. The new anaerobic digestion complex will come on line and then the
compost facility will be decommissioned.
With the changes, it is anticipated that the following equipment will become operational in
September 2020:
Add:
• Two Anaerobic Digesters
• One Sludge Holding Tank
• Digester Control building— Boilers and Pumps
• Dewatering Facility with Polymer Feed and Two Belt Presses
• Covered Dewatered Solids Pad
After start-up the following equipment is anticipated to be decommissioned in December 2020:
Remove:
• Two (2) belt filter presses
• Ten (10) bay sludge compost building
MISCELLANEOUS PERMIT MODIFICATION COMMENTS:
Total Silver
The draft permit that you have provided indicates that quarterly monitoring for Total Silver will
be implemented due the use of <5.0 ug/L by our contract laboratory on multiple occasions. You
have stipulated that that our PQL must be less than 1.0 ug/I. For some reason our laboratory
has shifted back and forth from PQL of 1.0ug/L to 5.0 g/L. We have brought this up to our
laboratory a couple of times.
Considering the fact that our sewer system has a pretreatment program and long term
monitoring (LTM) is required, the additional stipulation of this monitoring is not necessary. The
City will continue to monitor quarterly with the LTM and will issue a letter to our contract
laboratory indicating the correct PQL.
Mercury Minimization Plan:
Based upon the implementation of the dental amalgam rule during the permit cycle, the City of
Shelby would like to request that mercury minimization plan requirement be removed from this

permit. As you alluded to in the draft permit, there were no exceedances of the Water Quality
based limitations.
1, 4 - Dioxane
The draft permit alludes to the discharge of 1,4 Dioxane to the First Broad WWTP from a
groundwater remediation site at one of our local industries. The draft permit implements a
change to require monitoring for 1,4 Dioxane on a quarterly basis.
In Appendix A of this letter you will find data from this remediation site including flows and
data from periodic testing by their consultant. Based upon the low discharge flows from the
groundwater mediation activities and low discharge levels, the City would like to request that
this monitoring be added to the Effluent Pollutant Scan (Part I A.3.) which will be required
annually.
Toxici i Testing;
Based on the consistent pass rates for effluent toxicity and our 17% instream waste
concentration, the City would like to request that our facility be reduced to annual monitoring
for toxicity.
If you have any questions, please don't hesitate to contact me at 704-669-6570.
