NC0081256_Final Permit_20230224

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).

Facility Summary
This facility is a conventional water treatment plant. Filter backwash waster and sludge from the
super pulsator flows by gravity to lagoons (passing through dechlor on the way) operated in
series, where wastewater undergoes settling and clarification. Water continues to a decant lagoon
and an additional dechlor point, and then to UT Richland Creek outfall 002. During periods of
lagoon pump maintenance, facility discharges via gravity from outfall 001.
Compliance History — No enforcements or violations this permit cycle.
Toxicity — Failed of 3/18 tests from Jan 2017 — April 2021

303(d) language for Draft/Final Cover Letters: "Please note that the receiving stream is
listed as an impaired waterbody on the North Carolina 303(d) Impaired Waters List.
Addressing impaired waters is a high priority with the Division, and instream data will
continue to be evaluated. If there is noncompliance with permitted effluent limits and
stream impairment can be attributed to your facility, then mitigative measures may be
required".
Reasonable Potential Analysis (RPA)
Outfall 001
The maximum, monthly average flow between August 2018 and July 2021 (36 months) was 1.02
MGD
An RPA for Outfall 001 was conducted based on data submitted for Feb 2017 — July 2021 (4.5
years).
• Manganese — No RPA required; quarterly monitoring maintained as discharge is to WS
class waters (per current WTP guidance)
• Aluminum — No RPA required; quarterly monitoring maintained as discharge contains
alum (per current WTP guidance)
• Copper — No Reasonable Potential for exceedance of water quality standards found.
Quarterly monitoring removed.
• Fluoride — No reasonable Potential for exceedance of water quality standards found.
Limit has been removed, and monitoring reduced from monthly to quarterly. Quarterly
monitoring maintained as discharge contains fluoride.
Outfall 002
The maximum, monthly average flow between August 2018 and July 2021 (36 months) was 0.97
MGD
An RPA for Outfall 002was conducted based on data submitted for Feb 2017 — July 2021 (4.5

• Manganese — No RPA required; quarterly monitoring maintained as discharge is to WS
class waters (per current WTP guidance)
• Aluminum — No RPA required; quarterly monitoring maintained as discharge contains
alum (per current WTP guidance)
• Copper — No Reasonable Potential for exceedance of water quality standards found.
Quarterly monitoring removed.
• Fluoride — No reasonable Potential for exceedance of water quality standards found.
Limit has been removed, and monitoring reduced from monthly to quarterly. Quarterly
monitoring maintained as discharge contains fluoride.

NCG590000 General Permit Eligibility:
• They use conventional technology, therefore they are eligible
• They have passed 9 of the last 12 tox tests, therefore they are not eligible by tox
standards (updated to 11/12 at renewal)
• They do not discharge to HQW or ORW waters, therefore they are eligible
• They do not have limits for any parameters, therefore they are eligible
Conclusion: They are not eligible for the NCG59
Renewal Summary
• Updated discharge description language on the Supplement to Permit Cover Sheet
• Added description of treatment components to Supplement to Permit Cover Sheet
• Added facility classification above effluent table (A.1).
• Iron monitoring requirements have been removed from the permit. There are no longer
action level standards for this parameter.
• Turbidity monitoring was reduced to 2/month as there is no limit present (per current
WTP guidance)
• Copper Monitoring has been removed from the permit. Review of data from the past
permit cycle demonstrated no reasonable potential for the discharge of copper from this
facility to exceed water quality standards.
• Instream and effluent hardness monitoring requirements were removed. Copper was
previously the only hardness -dependent metal being sampled. As of this renewal,
copper monitoring requirements are removed, so hardness monitoring is no longer
needed.
• The limit for Fluoride has been removed, and monitoring has been reduced from
monthly to quarterly. Review of data from the past permit cycle demonstrated no
reasonable potential for the discharge of fluoride from this facility to exceed water
quality standards, however monitoring will remain since fluoride is used in the water
treatment process.
• 1,4-dioxane monitoring was added to A.(I) per draft 1,4-dioxane permitting
strategy with footnote for monitoring frequency reevaluation
o Removed for 2" d notice, no longer part of strategy
• The requirement to conduct sampling concurrent with WET testing is no longer part of
the Division's permitting strategy. The footnote requiring concurrent sampling with
WET testing has been removed from A(1).
• Section A. (2) has been updated to include language for electronic submittal of toxicity
results
• The language of Section A.(4) Electronic Reporting of Monitoring Reports has been
updated to be consistent with current federal requirements for electronic reporting.
211 Public notice (September 2022)
This facility was public noticed previously (October 2021) along with four other Water Treatment Plants. The
original notices included the proposed addition of monthly monitoring for 1,4 Dioxane. There was no limit
associated with this requirement, just monitoring and reporting. After completion of the notice process the
Division has reviewed and worked to update its strategy for addressing 1,4 Dioxane. The updated strategy will
not require monitoring for Water Treatment Plants, it instead focuses on areas that are more likely potential
sources of 1,4 Dioxane. Water Treatment Plants themselves do not appear to have sources of concern for 1,4
Dioxane. Raw water from surface waters used by Water Treatment Plants may possibly contain 1,4 Dioxane.
Where this is shown to be a potential issue the Division can work with the appropriate sources to require
monitoring at the water intake area for the Water Treatment Plants rather than as part of the plants' effluent
monitoring, as previously proposed. The proposed permit in this notice maintains all changes previously
proposed with the exception of removal of the monitoring requirement for 1,4 Dioxane.

RPA Permitting Guidance/WOBELs for Hardness -Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each
metal of concern, based on recent effluent data, and calculate the allowable effluent
concentrations, based on applicable standards and the critical low -flow values for the
receiving stream.If the maximum predicted value is greater than the maximum allowed
value (chronic or acute), the discharge has reasonable potential to exceed the standard,
which warrants a permit limit in most cases. If monitoring for a particular pollutant
indicates that the pollutant is not present (i.e. consistently below detection level), then
the Division may remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness -dependent metals the
Permit Writer compiles the following information:
• Critical low flow of the receiving stream, 7Q 10 (the spreadsheet
automatically calculates the 1 Q 10 using the formula 1 Q 10 = 0.843
(s7Q 10, cfs) 1.113
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, in
(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 can ditionsto total recoverable metal
at in -stream ambient conditions_ This factor is calculated using the linear
partition coefficients found in The 1'I efuls Translator•, Guidance, or•
Calcidating a Total Reco cable Pei -mit L?mitfrom a Dissolwd Criterion
(EPA 823-B-6-007, June 19`96) and the equation:
Cd.s - 1
Ct.bi 1 + I [ mil [ss l—a}l [10-11 }
Where:
ss = in -stream suspended solids concentration [mg..-1], minimum of 10 mg:I
nsed, and
po 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
, L --4- 1-1--1-A nrtr--
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) — (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 s7Q 10)
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:
IQ 10 = used in the equation to protect aquatic life from acute toxicity
QA = used in the equation to protect human health through the
consumption of water, fish, and shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each
pollutant of concern. Data entered must have been taken within four and one-
half years prior to the date of the permit application (40 CFR 122.21). The
RPA spreadsheet estimates the 95th percentile upper concentration of each
pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary. If the
predicted max exceeds the acute or chronic Total allowable concentrations,
the discharge is considered to show reasonable potential to violate the water
quality standard, and a permit limit (Total allowable concentration) is
included in the permit in accordance with the U.S. EPA Technical Support
Document for Water Quality -Based Toxics Control published in 1991.
7. When appropriate, permit writers develop facility specific compliance
schedules in accordance with the EPA Headquarters Memo dated May 10,
2007 from James Hanlon to Alexis Strauss on 40 CFR 122.47 Compliance
Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent
chromium and hexavalent chromium Water Quality Standards. As a cost
savings measure, total chromium data results may be used as a conservative
surrogate in cases where there are no analytical results based on chromium III
or VI. In these cases, the projected maximum concentration (95th %) for total
chromium will be compared against water quality standards for chromium III
and chromium VI.
9. Effluent hardness sampling and instream hardness sampling, upstream of
the discharge, are inserted into all permits with facilities monitoring for
hardness -dependent metals to ensure the accuracy of the permit limits and to
build a more robust hardness dataset.

For discharges associated with water treatment plants
S. Type of treatment plant:
® Conventional (Includes coagulation, flocculation, and sedimentation, usually followed by
filtration and disinfection)
❑ Ion Exchange (Sodium Cycle Cationic ion exchange)
❑ Green Sand Filter (No sodium recharge)
❑ Membrane Technology (RO, nanoflltration)
Check here if the treatment process also uses a water softener ❑
6. Description of source water(s) (i.e. groundwater, surface water)
Surface water
7. Describe the treatment process(es) for the raw water:
Most of the water consumers use is pumped from City Lake and processed into drinking water at the Ward Water
Plant on Pendleton Street. We have a state-of-the-art Super Pulsator treatment facility where we remove those
contaminants the water has picked up as it collects in our watershed. The Super Pulsator has 2 treatment trains
capable of treating 12 million gallons per day (MGD) in each train, for a total plant capacity of 24 MGD.
Coagulation takes place in our flash mix chamber on the Super Pulsator. First, we add alum (aluminum sulfate),
speeding the removal of most dirt and other large particulate matter. Settling is accomplished in the pulse chamber of
the Super Pulsator. As water enters the bottom of the pulse chamber it creates a sludge blanket that assist the settling
process as water moves through the blanket. Water is then filtered to remove smaller pieces of debris and bacteria in
each of our filters. We have four traditional filters and four "Green Leaf' filter, where the water is chemically treated
to kill any remaining bacteria. Each filter can treat up to 4 MGD.
Next, fluoride is added to protect teeth, and a Corrosion Inhibitor chemical to protect pipes are included. The water is
then stored in two elevated storage tanks at the plant. Finally, it is pumped into homes and businesses in High Point
and the surrounding areas.
8. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
Filter backwash water and sludge from the Super Pulsator, flows by gravity, to the lagoons where it passes through a
de -chlorination point before discharging into the North lagoon. This de -chlorination point is only used as needed.
Non -compliant chlorine samples are collected in the lagoons to monitor incoming chlorine levels. Once in the lagoon,
the solids can begin to settle out as the water clarifies. As the level in the North lagoon rises, water then moves to the
South lagoon. Valves are located at various depths to control the water level in the South lagoon.
From the South lagoon, water flows into the small decant lagoon where it is pumped by two 550 gallon per minute
lagoon pumps, into an unnamed tributary into Richland Creek at outfall 002. Before water flows into the creek, it
passes through our primary de -chlorination point where we use sodium sulfite tablets to remove residual chlor-
animated water from the filter backwashes.
During periods where we are performing maintenance activities with our two lagoon pumps, we can close off outfall
002 and discharge from outfall 001. Outfall 001 discharges from the south lagoon by gravity prior to entering the
small decant lagoon.
The lagoons are operated in series and, staff at the water treatment plant alternate lagoons, using one lagoon as a
primary treatment and the other lagoon as secondary treatment. These roles alternate depending on the sludge level in
each lagoon. Since the North lagoon was recently cleaned out in 2019, it currently serves as our primary lagoon.

Solids Handling Plan for the City of High Point
Solids Handling for the City of High Point is a coordinated effort between the Public Service Division and The City of High
Point Finance department. Solids are managed and monitored by staff at the Water treatment plant and Wastewater treatment
plants. The Water Plant Superintendent and Residual Management Superintendent monitor for the excessive buildup of
solids in the lagoons and initiate the budget process of selecting an approved "Residuals Handling" contractor. The City of
High Point Finance department awards the solids handling removal based off; price, quality of products offered, general
reputation of the bidder, conformity of intent of the specification and bidders' previous performance. Once a bidder is
accepted, they are required to adhere to the specification of the bid documents.
As solids build up in the lagoons from the Water Treatment process, the solids are divided into two lagoons (the north and
south lagoons). The lagoons operate in series with the lagoon having the less solids becoming our primary lagoon. On a
rotating bi-annual basis, either the North or South, lagoon is cleaned out by a City approved contractor.
The specifications for our most recent Solids Handling event, which occurred in February 2019, are described below, with a
list of Contractor proposals and responsibilities:
