solution because the original bids came in approximately $7,000,000 over estimate; and
the addition of construction staking to try and save the contractor's markup for the work.
The respective additional costs are: $54,457.11; $232,499.22; and $37,346, which result •
in additional engineering fees of$324,302.33.
There was a very brief discussion on the additional engineering fees.
Mr. 3,arnhart made the motion to approve an increase of $324,302.33 in
engineering fees to Hazen and Sawyer for the Lower Rocky River Interceptor Force
Main and Pump Station Mr. Fowler seconded the motion and the ►:,oard approved
by unanimous vote.
Consideration for Approval of Amendment No. 1 to the Sewer Use Ordinance
Mr. Murdock stated that a study, performed by Black & Veatch, Inc., found the �\
Rocky River Regional Wastewater Treatment Plant (RRRWWTP) is capable of handling u6_
and processing additional solids. Current surcharge concentrations are based upon design
and domestic sewage levels at the RRRWWTP. Monitoring has shown TSS
concentrations in typical domestic sewage at 220-250 mg/L. Staff recommends
increasing the TSS surcharge concentration to 250 mg/L.
Mr. Murdock provided a Notice of Intent, which requires WSACC to give the
jurisdictions a sixty (60) day notice of the pending change, as required by the N.C.
Statutes. He stated that this would create a reduction in revenues to WSACC.
There was a very brief discussion on the Amendment and the Notice of Intent.
Mr. Rape made the motion to approve the Declaration of Intent to the Sewer
Use Ordinance. Mr. Goodnight seconded the motion al the toard approved by
unanimous vote.
Mr. Murdock briefly mentioned the fact that Pillowtex-Fieldcrest Cannon, Inc., is
interested in giving up 2,000,000 gallons of capacity at the RRRWWTP. CMU may be
interested in picking up the 2,000,000 gallons of capacity at a cost of$4 — $6 per gallon.
If CMTJ picks up the 2,000,000 gallons, it would be forever. WSACC would clear
approximately$2 per gallon on selling the capacity to CMU.

Dear Mr.Hassan:
Over the past few years, the Water and Sewer Authority of Cabarrus County has seen an
increase in domestic ammonia loadings to the Rocky River Regional Wastewater Treatment Plant
( (RRRWWTP). WSACC obtained Hazen and Sawyer to evaluate ammonia loadings and determine
new design criteria. !rased upon Hazen and Sawyer's findings, the ammonia design criteria can be
increased to 30 mg/L. WSACC has enclosed a copy of the report for your review.
WSACC is requesting PERCS to increase the ammonia design value in the headworks
analysis calculations to 30 mg/L. Please note WSACC has not had any violations of its ammonia
limits contained in the NPDES permit for the RRRWWTP.
If you have any questions, please feel free to contact me at [phone], ext. 112 or
Ivi tcalf�,wsacc.org . Thank you for your time and consideration concerning this matter.
Sincerely,

JUSTIFICATIONS FOR
2022 HEADWORKS ANALYSIS
ROCKY RIVER REGIONAL WASTEWATER TREATMENT PLANT
HWA Data Time Period:
Sampling for all long term monitoring plan pollutants of concern was performed
February 2019 through March 2022 at the WWTP influent and effluent. SIU monitoring
was conducted either monthly or quarterly. Three years of monitoring data was used for
the mass balance.
II. WWTP Design Criteria:
DEQ requested WSACC to submit an HWA for both the current permitted flow of 26.5
mgd and approved expansion flow of 30.0 mgd. No changes were made to the design
values for the RRRWWTP expansion.
WSACC has elected to use Option 2 of PERCS February 2007 letter, applying the 1.5
multiplier to current design criteria for BOD and TSS. WSACC has been in full
compliance for these parameters. These same design values were also used in the last
three HWAs approved by DWQ in 2008, 2012 and 2017. WSACC has not exceeded its
NPDES limits in the past two years.
III. Influent Data:
Influent data (INT average) is based upon combined interceptors and septage data. The
influent CBOD data was taken from the DMRs, which use Box 10 for the monitoring
site.
IV. Silver Data:
WSACC received silver monitoring requirements in its NPDES permit effective
November 1, 2021. Therefore, limited silver data was available in calculating this HWA.
V. Calculations for BOD Limit Used in Headworks Analysis:
BOD =291 mg/L
CBOD =264 mg/L
BOD/CBOD Ratio= 1.1
NPDES CBOD Limit= 15.4 mg/L
Calculated BOD Limit= 15.4 * 1.1 = 16.9 mg/L
VI. Removal Rates: (Please note V2 detection level is used in calculations)
BOD, COD, CBOD, TSS, Ammonia, Copper, Lead, Nickel and Zinc are based upon site-
specific data.

ROCKY RIVER REGIONAL WASTEWATER TREAT Mil PLANT
Mercury is based on upon site-specific data. With the new NPDES permit for
RRRWWTP, effective November 2021, WSACC changed the detection level for effluent
mercury monitoring from low level to 0.2 ug/l. Although the mercury monitoring for
November 2021 and February 2022 were less than DL, this change caused the removal
rate to go from 98.63%to 88.06%. These results are not representative of our plant's true
removal capabilities. After discussion with Keyes McGee on 5/25/22, WSACC received
verbal approval to omit the November 2021 and February 2022 effluent mercury results.
For the next HWA, WSACC will return to low level mercury monitoring and update the
LTMP to reflect those changes.
Arsenic, Cadmium, Chromium and Selenium are based upon literature data - >50% of
data is below detection level.
Silver: All the data is below detection level; however, a much lower detection level is
used for the effluent. WSACC was able to manually calculate the removal rate.
Beryllium: Based upon literature data provided by DEQ (see copy of email in Tab 3) -
>50% of data is below detection level. Beryllium is not required in permits or the LTMP
and it is not a pollutant of concern for the RRRWWTP.
VII. Uncontrollable Concentrations Used: (Please note %2 detection level is used in
calculations)
BOD, COD, TSS, Ammonia, Beryllium, Copper, Mercury, Selenium, and Zinc are based
on mass balance.
Arsenic, Cadmium, Chromium, Lead, and Nickel are based on literature data. The higher
concentrations will further protect the plant. Industrial customers do not have a demand
for additional loadings of these pollutants.
Silver: All waste streams (influent, effluent, uncontrollable) less than detection level,
therefore, we chose to enter zero. DEQ provided this as an option in letter dated March
21, 2022.
VIII. Industrial flows:
The industrial average flows were calculated separately from the industrial data summary
forms because we collect daily flows from many users and monthly for all others. This
provides us with a broader data set as opposed to just the flows collected during sampling
events. These averages can be found at the end of Tab 7.
IX. The Pretreatment Program Information for WSACC is in Tab 9. Corrections are marked
in red. WSACC currently has 14 SIUs at the Rocky River Regional WWTP and 15 total
SIUs in the program.

JUSTIFICATIONS FOR
2022 HEADWORKS ANALYSIS
ROCKY RIVER REGIONAL WASTEWATER TREATMENT PLAN.
X. Water Quality Standards:
The recent NPDES permit renewal used the Freshwater RPA Using Metal Translators to
evaluate the data to determine if permit limits were required. The Total Metal Allocated
to the Permittee were used in the HWA spreadsheet as the water quality standards (Tab
13). The more stringent human health criteria was used for arsenic; chromium was
evaluated using the more stringent CR VI criteria; the more stringent water supply
criteria was used for nickel; and the more stringent acute total metal allocated was used
for zinc. It is understood that only the shaded parameters on the calculator spreadsheet
are hardness dependent and make use of EPA translators to calculate the total metal
allocated.

accordance with 15A NCAC 02D.2600 and follow the procedures outlined below:
1. The owner or operator of the source shall arrange for air emission testing protocols to be provided to the Director
prior to air pollution testing. Testing protocols are not required to be pre-approved by the Director prior to air
pollution testing.The Director shall review air emission testing protocols for pre-approval prior to testing if
requested by the owner or operator at least 45 days before conducting the test.
2. Any person proposing to conduct an emissions test to demonstrate compliance with an applicable standard shall
notify the Director at least 15 days before beginning the test so that the Director may at his option observe the test.
3. The owner or operator of the source shall arrange for controlling and measuring the production rates during the
period of air testing.The owner or operator of the source shall ensure that the equipment or process being tested is
operated at the production rate that best fulfills the purpose of the test.The individual conducting the emission test
shall describe the procedures used to obtain accurate process data and include in the test report the average
production rates determined during each testing period.
4. Two copies of the final air emission test report shall be submitted to the Director not later than 30 days after sample
collection unless otherwise specified in the specific conditions. The owner or operator may request an extension to
submit the final test report.The Director shall approve an extension request if he finds that the extension request is a
result of actions beyond the control of the owner or operator.
a. The Director shall make the final determination regarding any testing procedure deviation and the validity of the
compliance test.The Director may:
i. Allow deviations from a method specified under a rule in this Section if the owner or operator of the source
being tested demonstrates to the satisfaction of the Director that the specified method is inappropriate for
the source being tested.
ii. Prescribe alternate test procedures on an individual basis when he finds that the alternative method is
necessary to secure more reliable test data.
iii. Prescribe or approve methods on an individual basis for sources or pollutants for which no test method is
specified in this Section if the methods can be demonstrated to determine compliance of permitted emission
sources or pollutants.
b. The Director may authorize the Division of Air Quality to conduct independent tests of any source subject to a
rule in this Subchapter to determine the compliance status of that source or to verify any test data submitted
relating to that source. Any test conducted by the Division of Air Quality using the appropriate testing
procedures described in Section 02D.2600 has precedence over all other tests.

Ia. Denotes metals for which Aquatic Life Criteria are expressed as a function of total hardness.
*Arsenic has a Human Health standard of 10 ug/L is more stingent than the freshwater standards. The Permit limit
for arsenic would be determined by taking the Human Health Standard and dividing it by an IWC based on the mean
annual flow of the receiving stream and the permitted plant flow.
IIWC=Permitted Flow+(Permitted Flow+mean annual average)
**Nickel has a Water Supply standard of 25 ug/L and in most cases is more stringent than the freshwater standard.
The Permit limit for nickel using the 25 ug/L WS standard would be determined by dividing 25 by an IWC based on
