Briefly describe the proposed permitting action and facility background: This conventional water
treatment plant will be designed to produce 13 MGD of potable water. Treatment will consist of rapid
mix, flocculation, sedimentation, and gravity filtration (GAC). Residuals blowdown from sedimentation
basins, filter -to -waste, and filter backwash will be delivered to reclamation basins. Supernatant from
basins (up to 10% of plant flow) will be pumped back to the front of the conventional trains. Sludge will
be dredged every 6 months from the basins. Supernatant will be reclaimed to the extent possible, with
the NPDES discharge permit being utilized as needed for daily operations. Thiosulfate will be added to
any water discharged to remove residual chlorine. Filter backwash will use finished water.
Initial wastewater flow is estimated to be 0.29 MGD, reaching 0.47 MGD within 5 years.

3. Data Summary
Union county conducted a source water study for the proposed discharge using Norwood WTP, which
also draws water from Lake Tillery and is assumed to be a good representative waste stream.
Union county was advised that if an NPDES permit is approved, Union County will be responsible for
passing the toxicity test assigned in that permit or risk shutting down. Since Union County chose to
perform the source water study using the wastewater from another water treatment plant, this
proposed project could be taking the risk of not passing the appropriate toxicity test if the preliminary
study does not reflect the proposed water treatment plant's source water. Union County will be
responsible for meeting all surface water quality standards at the actual proposed discharge location,
should the permit be approved.

4. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and Mixin Zones
ones
In accordance with 15A NCAC 213.0206, the following streamflows are used for dilution considerations
for development of WQBELs: 1 Q 10 streamflow (acute Aquatic Life); 7Q 10 streamflow (chronic Aquatic
Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).
If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): NA
If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): NA
Page 3 of 7

Oxygen -Consuming Waste Limitations
Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD= 30 mg/l for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe how limits were developed: This facility will not
produce any oxygen consuming waste
Total Residual Chlorine Limitations
Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection
of aquatic life (17 ug/1) and capped at 28 ug/l (acute impacts). Due to analytical issues, all TRC values
reported below 50 ug/l are considered compliant with their permit limit.
Describe any TRC limits for this permit l: A limit of 17 ug/L was put in place.
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 1/2 detection limit for "less than" values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
A reasonable potential analysis was conducted on data collected between July 2019 and 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. No parameters will receive a water quality -based effluent limit
(WQBEL) since none demonstrated a reasonable potential to exceed applicable water quality
standards/criteria.
• 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: lead,
copper, arsenic
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since
they did not demonstrate reasonable potential to exceed applicable water quality
standards/criteria and the maximum predicted concentration was <50% of the allowable
concentration: Chlorides, radioactive parameters.
A maximum discharge of 4.5 MGD was used for the RPA, because the application notes that discharge
may reach 4.5 MGD during startup.
Page 4 of 7

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: Chronic pass/fail ceridodaphnia dubia at 90%, quarterly
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: TN/TP monitoring according to 2009 WTP permitting strategy
Other WQBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: NA
If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall
comply with in order to protect the designated waterbody: NA
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with
15A NCAC 2H 0107( c) (2) (B), 40CFR 122. 47, and EPA May 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
5. Technology -Based Effluent Limitations (TBELs)
Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/l
BODS/TSSfor Monthly Average, and 45 mg/l for BODS/TSSfor Weekly Average). TSS for WTPs
If NO, provide a justification for alternative limitations (e.g., waste stabilization pond).
6. 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 213.0201. 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
Page 5 of 7

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:
EAA- Feasible Alternatives:
1. Connect to WWTP —no nearby POTW has capacity to treat the estimated 0.49 MGD from
this facility, and no nearby POTW is planning to expand capacity in next 5 years.
There are no planned sewer systems in the vicinity
2. Land application — soils rated as "very limited" in terms of suitability for land -based
application. Would need 120 acres to land apply, costing —5 million in land acquisition alone
(estimated 12.8 mil for land, equipment, and O&M costs.) Not economically feasible.
3. Wastewater reuse — Plant recycles supernatant from basins, recirculating up to 10% of total
flow
4. Surface water discharge — opinion of CDM Smith that this is the only viable option
5. Combining wastewater reuse and surface water discharge to maximum allowable extent. No
other viable combinations of aforementioned alternatives
The Division agrees with the applicant's assessment that discharge to surface waters is a necessary means
of wastewater disposal. Discharge to UT Richardson Creek will not harm existing water uses or water
quality.
7. 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).
NA
8. 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 213.0500; 2)
NPDES Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance,
Reduced Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best
Professional Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not
considered effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti -
backsliding prohibitions would not be triggered by reductions in monitoring frequencies.
9. Electronic Reporting Requirements
Page 6 of 7

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.

1. Expected criteria, based on NC -EPA Standards Table, June 2019
2. Water quality criteria for alkalinity is a minimum value, exept where alkalinity is naturally lower. Alkalinity data not available for unnamed on -site tributary at Outfall
001; raw water alkalinity from Lake Tillery is low: 15-26 mg/L
3. Where necessary, hardness -dependent criteria were calculated uising the minimum applicable instream hardness of 25 mg/L as no hardness data is available for the
proposed discharge location.
4. From EPA Final Aquatic Life Ambient Water Quality Criteria for Aluminum, 2018. Assuming DOC of 1.0 mg/L, pH of 7.5, and hardness of 25 mg/L.
5. EPA approved removal of NC aquatic life standard as part of 2007-2016 Triennial review due to high natural occurrence in NC surface waters. The EPA NRWQC remains
here as guidance for instances when toxicity information is needed.
6. EPA approved removal of NC human health standards as part of 2007-2016 Triennial review due to high natural occurrence in NC surface waters. The EPA NRWQC
remains here as guidance for instances when toxicity information is needed.

Emily,
We noticed in the draft NPDES permit for the Union County Yadkin River WTP (NC0089893) in the
Supplement to Permit Cover Sheet on Page 3 of the PDF that the maximum monthly average
discharge is noted as 0.47 mgd. I think this is one of the items we clarified in the March 17 email
addressing the questions. The flow should be 0.49 mgd rather than 0.47 mgd. The 0.47 mgd is the
number we used in the letters to the owners of the surrounding WWTPs in the EAA, because that is
the flow expected at the 5-year milestone, but we updated the EAA and application to reflect the
0.49 MGD number.
Is that something that can be corrected for the Final Permit?
Also — have you received many (or any?) comments on the Draft Permit?
Thanks,
Kelly

Hi Emily,
Here are the answers to your questions — answers are in red.
1. My notes from our initial meeting last year state that the Norwood WTP, whose effluent was
used in your process wastewater sampling study, has the same source water as the proposed
Yadkin River WTP (Lake Tillery.) I don't see this stated anywhere in the application materials,
so I just wanted to double check with you to get confirmation on that.
The reason I ask is that if an NPDES permit is approved, Union County will be responsible for
passing the toxicity test assigned in that permit or risk shutting down. Since Union County
chose to perform the source water study using the wastewater from another water
treatment plant, this proposed project could be taking the risk of not passing the
appropriate toxicity test if the preliminary study does not reflect the proposed water
treatment plant's source water. Union County will be responsible for meeting all surface
water quality standards at the actual proposed discharge location, should the permit be
approved.
This is correct— Norwood's water source is the same as the proposed Yadkin River WTP's
source (Lake Tillery), so we used their process wastewater as a surrogate for the new plant.
We added a sentence in the last paragraph of Section 1.2.1 of the EAA to clarify this. We
understand the new Yadkin River WTP will have toxicity in its permit. Based on the success of
the toxicity tests performed, we feel the toxicity tests will be able to be met.
2. Regarding funding — is this project receiving any funding from a federal agency (EPA, USDA,
etc.) or state agency? This is to determine whether the project requires NEPA or SEPA review.
No, this project is not receiving any federal or state agency funding.
3. 1 came across two different numbers for maximum flow in the application. In some places, the
application states Max flow will be 0.47 MGD, and in others, 0.49 MGD. Can you confirm for
me which is correct? The correct flow is 0.49 mgd. We referred to the flow as 0.47 mgd in the
letters to the owners of the surrounding WWTPs in the EAA, because that is the flow expected
at the 5-year milestone. We have clarified the max flow in the last paragraph of Section 1.1,
the last sentence of Section 2.2, and the first part of Section 3 of the EAA. The revised EAA is
attached.

4. In the Application Short Form C, the applicant did not mark that Fluoride had any potential to
be discharged. However, I see that in the process diagrams, finished water containing fluoride
is used for filter backwash, which would indicate there is potential for it to be discharged. Can
you confirm whether Short Form C or the process diagram is correct? The process flow
diagram is correct — the omission on Short Form C was an oversight. Fluoride will be added
both before and after the finished water storage; therefore, it is possible that fluoride will be
present in the filter backwash water and in the NPDES discharge. We have updated Short
Form C to reflect this, and the updated and re -signed form is attached.
Do you prefer that I submit this by letter/mail, or is this email response OK? Do you need any hard
copies?
Also, one last question — can you please let us know of the public notice date so we can let the
County know? We weren't sure if the dates had been affected by the work restrictions due to the
virus.
Thanks,
Kelly

Subject: Yadkin River WTP application review
Hi Kelly,
I have an update for you on the Yadkin River Water Treatment Plant NPDES permit application. I
have met with the engineers, who have completed review of the EAA and agree that discharge is the
most viable wastewater option for this project. The EAA is approved for discharge to the Unnamed
Tributary to Richardson Creek.
I am hopeful that, pending review by the regional office and central office staff, the draft permit may
be able to go to public notice on the next public notice date, 03/25/20, or the following notice date,
04/08/20. This is subject to delay should we receive any major comments from staff.
I have a few questions for you before finalizing the draft:
1. My notes from our initial meeting last year state that the Norwood WTP, whose effluent was
used in your process wastewater sampling study, has the same source water as the proposed

Yadkin River WTP (Lake Tillery.) I don't see this stated anywhere in the application materials,
so I just wanted to double check with you to get confirmation on that.
The reason I ask is that if an NPDES permit is approved, Union County will be responsible for

chose to perform the source water study using the wastewater from another water
treatment plant, this proposed project could be taking the risk of not passing the
appropriate toxicity test if the preliminary study does not reflect the proposed water
treatment plant's source water. Union County will be responsible for meeting all surface
water quality standards at the actual proposed discharge location, should the permit be
approved.
2. Regarding funding — is this project receiving any funding from a federal agency (EPA, USDA,

3. 1 came across two different numbers for maximum flow in the application. In some places, the

Good morning Kelly,
As mentioned during the meeting yesterday regarding the proposed Union County WTP, please find
below additional information that must be submitted with new WTP permit applications. Attached
are some items you will need to move forward with the application for a proposed Water Treatment
Plant.
1. NPDES application — use NC Short Form C for Water Treatment Plants and EPA Major
industrial facility Application if discharge > 1 MGD.
MAJOR INDUSTRIAL FACILITIES (if the discharge is > 1 MGD assume this permit
application will be for a major facility — an EPA rating sheet will be completed by the
permit writer)
EPA Form 1: Major Industrial Facilities, plus 1 of the following:
EPA Form 2D: New facilities
2. EAA Guidance — an Engineering Alternatives Analysis assessing other wastewater disposal
methods & costs, must be submitted with all new permit applications. See attached EAA
Guidance.
3. In accordance with the NPDES WTP Permitting Strategy (attached), the permittee shall
demonstrate that there will not be a significant impact to the receiving stream. Therefore,
analysis should be performed on the wastewater. See a list of parameters to analyze under
item #5 below. In addition, three Whole Effluent Toxicity tests should be conducted. The
Permittee can contact Cindy Moore at the DWR Aquatic Toxicity Branch to confirm the
appropriate test to perform at 919-743-8401.
4. Please be sure to include the following items with the application:
• Describe the treatment processes for the raw water. Provide a schematic of flow
through the facility which includes flow volumes at all points in the water treatment
process. The plan should show the point[s] of addition for chemicals and all discharges
routed to the outfall.
• Describe any wastewater treatment processes provided for the wastewater
generated by the facility.
. The map with the receiving stream should identify exactly where the discharge (or

diffuser) will enter the stream (longitude and latitude). It should also outline the path
the discharge pipe will follow from the facility to the discharge point at the stream.
5. Since this is a proposed facility, the application should include:
• Analyses of source water collected (Baseline Raw Water Monitoring Data)
• Analysis of wastewaters for the following parameters:
Aluminum, Arsenic, Barium, Beta Particles, Calcium, Chloride, Copper, Iron,
Magnesium, Manganese, Ammonia -Nitrogen, Nitrogen -Nitrate + Nitrite, Total
Hardness (CaCo3), Total Phosphorus, Total Nitrogen [TN= TKN + (Nitrites+Nitrates)],
Total Dissolved Solids, Total Suspended Solids, Zinc, Lead, pH, Radium 226 & 228
(pCi/L), Chronic Toxicity test(s) using Ceriodaphnia dubia at 90% effluent
concentration or estimated dilution (or perform a multi -concentration test).
If available, submit data on Phosphate as P, Total Alkalinity (as CaCO3), Bicarbonate,
Carbonate, Hydroxide Alkalinity, Silica, Sulfate, Sodium and additional radiological
components if expected to be present.
Please let us know if you have any questions.
