2. Submit a written request for remission including a detailed justification for
such request: ' .
Please be aware that a request for remission is limited to consideration of the five
factors listed below as they may relate to the reasonableness of the amount of the
penalty assessed. Requesting remission. is not the proper procedure for contesting
whether the violation(s) occurred or the accuracy of any of the factual statements
contained in the civil penalty assessment document. Because a remission request
forecloses the option of an administrative hearing, such a request must be
accompanied by a waiver of your right to an administrative hearing and a
stipulation that no factual or legal issues are in dispute. Please prepare a detailed
statement that establishes why you believe the civil penalty should be remitted,
and submit it to the Division of Water Quality at the address listed below. In
determining whether a remission request will be approved, the following factors
shall be considered:
(1) whether one or more of the civil penalty assessment factors in G.S. 143B-
282.1(b) were wrongfully applied to the detriment of the petitioner;
(2) whether the violator promptly abated continuing environmental damage
resulting from the violation;
(3) whether the violation was inadvertent or a result of an accident;
(4) whether the violator had been assessed civil penalties for any previous
violations; or
(5) whether payment of the civil penalty will prevent payment for the
remaining necessary remedial actions.
Please note that all information presented in support of your request for remission
must be submitted in writing. The Director of the Division of Water Quality will
review your evidence and inform you of his decision in the matter of your
remission request. The response will provide details regarding case status,
directions for payment, and provision for further appeal of the penalty to the
Environmental Management Commission's Committee on Civil Penalty
Remissions (Committee). Please be advised that the Committee cannot consider
information that was not part of the original remission request considered by the
Director. Therefore, it is very important that you prepare a complete and thorough
statement in support of your request for remission.
In order to request remission, you must complete and submit the enclosed
"Waiver 'of Right to an Administrative Hearing and Stipulation of Facts" form
within thirty (30) days of receipt of this notice. The Division of Water Quality
also requests that you complete and submit the enclosed "Justification for
Remission Request." Both forms should be submitted to the following address:

Dear Mr. Sides:
Alan W. Klimek, P.E. Director
Division of Water Quality
A review of the June and July 2006 self -monitoring reports for the subject facility and a
phone conversation with the Operator in Responsible Charge revealed that chlorine monitoring at
the Mt. Pleasant High School WWTP had been discontinued. Although your Engineer's.
certification for the completion of construction (AtC #077704A01) was submitted to the
Construction Grants & Loans Section, the Point Source Branch of the Division of Water Quality
was not notified as to the status of your project. Therefore, your permit has not been modified
and the chlorine monitoring requirements contained in your permit are still in effect.
To help expedite processing, please submit a brief written permit modification request to
the Division of Water Quality that includes the following information: 1) the status of the
chlorine facilities at the WWTP, 2) the status of the ultraviolet disinfection system, and 3) your
desire to have the permit requirements for chlorine monitoring modified.
Please address your response to the attention of Mr.. Bob Sledge of the Point Source

Dear Mr. Leslie:
This letter is in regard to Mt. Pleasant Wastewater Treatment Plant's failure of the Fecal
Coliform test for the week of October 16`h through the 201h . The daily fecal was 2100ml on the
sample collected October 18, 2006. I contacted your office on October 19'h to report this violation and
believe that the heavy rain that week may be the cause of the problem.

following parameter(s):
PARAMETER
NH3 as N
PARAMETER
NH3 as N
DAILY MAX. REPORTED DAILY LIMIT
45.06 MG/L 35 MG/L
MONTHLY AVERAGE MONTHLY LIMIT
13.4 MG/L 7 MG/L
After the daily exceedence of 45.06 I contacted you at your office in the morning of June
27, 2006. Following your advice I contacted the School and asked if they had stripped the floors
on the 26th. They informed me that they had, but they did not put the waste into the sewer
system. The NH3 reading for the 27th dropped to 5.90 MG/L.
This Facility has been recently upgraded to meet the new NH3 limits and we have been
experimenting with different air configurations to get optimum -performance. We took NH3
readings from June 26 through June 30, 2006 in an attempt to figure out the problem. After
adding more air to the wet well just before the sand filter we were able to bring the NH3 down to
0.300 MG/1 on June 30, 2006. I cannot be sure what caused the spike of 45.06 MG/1 on June
26th, but I do feel that we have the previous high NH3 levels under control.

Dear Mr.. Goodrich:
The purpose of this letter is to review the correspondence and activity'that has occurred over the past
28 months related to the wastewater treatment plant at Mount Pleasant High School, and the
improvements. now underway there, in an effort to comply with new effluent limits now in effect for
ammonium nitrogen and for chlorine residuals. The purpose of this letter is also to inform you of job
progress to date, and to request that the Division of Water Quality be willing to forgive any fines
or financial penalties -that may accrue to Cabarrus County Schools during the next 3 months as
the improvements are being completed,. and as the revised facilities are being placed into .
satisfactory operation.
NPDES Permit #NC0077704 was issued to Cabarrus County Schools for Mount.Pleasant High
School Wastewater Treatment Plant on October 29, 2003, with effective date of December 1, 2003.
Said permit established new effluent limitations for "NH3 as N" during the April 1 through October
31 period, as well as for "Total Residual Chlorine", with new limits beginning on January 1, 2005.

Cabarrus County Schools began assessing, in early 2004, the likelihood of the existing wastewater
treatment plant being operated in compliance with the new effluent limits, and employed David A.
Roberts, P.E. of Landis'. N.C. as Consulting Engineer to offer engineering oversight, advice and
planning.
On March 31, 2004, a 3-page letter was sent from the engineer and from Mr. Donald F. Clickner,
Director, Facilities, Operations & Construction, Cabarrus County Schools, to Mr. Dave Goodrich,
Supervisor, NPDES Unit, Division of Water Quality, outlining plans for an operations study, to see if
the plant could be operated in compliance with the new effluent limits without requiring major capital
improvements. Said letter outlined 4 proposals for the operations study, and requested approval of
them.

On May 26, 2004, a 2-page letter was sent from Mr. Alan Klimek, P.E., Director, Division of Water
Quality, to Mr. Donald F. Clickner, Director, Facilities, Operations & Construction, Cabarrus County
Schools, granting permit modification and permission to follow the requested 4-step plan of action,
including postponing compliance with new effluent limits for Ammonia -Nitrogen until 10/31/2005,
while still requiring compliance with the new Total Residual Chlorine limits by June 1, 2005.
The operations study was continued past October 31, 2004, until early 2005, and the results showed
that the existing wastewater treatment facilities could not consistently operate in compliance with the
new Ammonia -Nitrogen effluent limits, without making major capital improvements to the existing
facilities. The engineer began, in early 2005, the process of designing and detailing the proposed
improvements to the existing wastewater treatment facilities, with engineering plans and
specifications being finalized in early April of 2005.
On April 25, 2005, a 2-page letter was sent from the engineer and from Mr. Donald F. Clickner,
Director, Facilities, Operations & Construction, Cabarrus County -Schools, to Mr. Dave Goodrich,
Supervisor, NPDES Unit, Division of Water Quality, in which the results of the operations study was
described, 5 sets of engineering plans and specifications were conveyed, and issuance of an
"Authorization to Construct" was requested for the proposed improvements to the wastewater
treatment plant at Mount Pleasant High School. Said letter clarified that the proposed improvements
would include installation of ultraviolet disinfection equipment, along with the abandonment of the
existing tablet chlorination equipment and the existing chlorine contact tank. Said letter clarified that
engineering plans include construction of a recirculating dosing tank with effluent pumps and float
control switches, pump control panel, and sand filter bed.
Said letter also requested that, since chlorine would be discontinued as a disinfectent, and since
ultraviolet disinfection equipment would be utilized, then it is requested that the Total Residual

Chlorine limit established fog- this plant be eliminated from the permit requirements, effective
upon completion of installation of the ultraviolet disinfection equipment and upon completion of
construction of the improvements to the wastewater treatment plant.
On July 11, 2005, a 1-page letter, with 2-page attachment entitled "Request for Additional
Information", was sent from Mr. Cecil G. Madden, Jr., P.E., Supervisor, Construction Grants and
Loans Section, Design Management Unit, to Mr. Donald F. Clickner, Director, Facilities, Operations
& Construction,, Cabarrus County Schools, wherein the request for "Authorization to Construct" was
acknowledged, the project review officer was identified as Mr. Ishwar C. Devkota, P.E., and a listing
of 13 items of additional information was identified.
On August 6, 2005, a fax letter was sent from the design engineer, Mr. David A. Roberts, P.E., to the
review officer, Mr. Ishwar C. Devkota, P.E., outline design criteria utilized in sizing the recirculating
sand -filter bed, with design advice from Mr. Bob DeWeese, P.E. of the North Carolina Department of
Public Instruction.

Another fax letter was sent from Mr. -David A. Roberts, P.E. to Mr. Ishwar C. Devkota, P.E., on
August 10, 2005, wherein the design engineer requested more time to complete the redesign and
redrawing of the engineering plans so as to incorporate the changes mandated by the review officer,
and as follow up to the "Request for Additional Information." The design engineer prepared new
engineering plans and specifications for the proposed improvements to the existing wastewater
treatment plant during the following 3-month period..
On November 10, 2005, a letter was sent from Mr. David A. Roberts, P.E. to Mr. Ishwar C. Devkota,
P.E., Division of Water Quality, wherein engineering plans and specifications, along with supporting
documents, were conveyed, along with a request for issuance of the "Authorization to Construct" for
this project.
On December 10, 2005, a letter was sent from Mr. Alan W. Klimek, P.E. to Mr. Donald F. Clickner,
Director, Facilities, Operations & Construction, Cabarrus County Schools, issuing "Authorization to
Construct #077704A01" for this project.
On December 20, 2005, the Consulting Engineer and the Owner established a date for receiving bid
proposals for the work required for this project, and agreed on the wording of the "Advertisement for
Bids". The "Advertisement for Bids" was mailed to prospective bidders on December 24, 2005. Bid
documents were issued to interested bidders. Bid proposals were received, opened and read on
January 19, 2006. Due to an error in one of the bid proposals, the Owner rejected the original bids and
readvertised the project for bids. Bid proposals were received, opened and read again on January 26,

an awareness of the status of progress made to date on this project.
It is requested that the Total Residual Chlorine limit established for this plant be eliminated
from the permit requirements, effective upon completion of installation of the ultraviolet
disinfection equipment- and upon completion of construction of the improvements to the wastewater
treatment plant.. It is also requested that the Division of Water Quality be willing to forgive any

2.. Submit a written request for remission including a detailed justification for
such request:
Please be aware that a request for remission is limited to consideration of the five
factors listed below as they may relate to the reasonableness of the amount of the
penalty assessed. Requesting remission is not the proper procedure for contesting
whether the violation(s) occurred or the accuracy of any of the factual statements
contained in the civil penalty assessment document. Because a remission request
forecloses the option of an, administrative hearing; such a request must be
accompanied by a waiver of your right to an administrative hearing and a
stipulation that no factual or legal issues are in dispute. Please prepare a detailed
statement that establishes why you believe the civil penalty should be remitted,
and submit it to the Division of Water Quality at the address listed below. In
determining whether a remission request will be approved, the following factors
shall be considered:
(1) whether one or more of the civil penalty assessment factors in G.S. 143B-
282.1(b) were wrongfully applied to the detriment of the petitioner;
(2) whether the violator promptly abated continuing environmental damage
resulting from the violation;
(3) whether the violation was inadvertent or a result of an accident;
(4) whether the violator had been assessed civil penalties for any previous
violations; or
(5) whether payment of the civil penalty will prevent payment for the
remaining necessary 'remedial actions.
Please note that all information presented in support of your request for remission
must be submitted. in writing. The Director of the Division of Water Quality will
review your evidence and inform you of his decision in the matter of your.
remission request. The response will'provide details regarding case status,

CONSTRUCTION SEQUENCE FOR PLANT MODIFICATIONS:
1. Lay out on the site the location and boundary of the proposed improvements, such as the recirculating
sand filter bed, the flow splitter box, the ultraviolet disinfection well, and the dosing tank. Coordinate with
Cabarrus County Schools maintenance personnel to locate in the field all known underground facilities,
such as: irrigation piping; potable water piping; electric lines; stormwater piping; and others. Where new
system improvements will cross existing underground services, carefully excavate at these locations to find
The underground services, and note their location, depth, size and material -composition, then -determine the
impact those existing underground services will have, if any, on the installation of the proposed
improvements. Keep the engineer informed of these findings, and get his approval for any adjustments to
be made.
2. Remove the existing woven wire fencing from the.existing soccer practice field as required to
accommodate the sand filter bed installation.

* Economically priced
* Two-year I i m ited warranty
This attractive, top-quality alarm system is designed to provide residential and commercial applications
With a dependable yet economical high or low liquid level warning device. With the sound of a loud pulsating
horn plus the flash of a large, red light, the customer is cautioned of potentially threatening liquid level
conditions.
Description: The non -corrosive, indoor and outdoor
panel enclosure comes with attached light and -horn
pre -assembled and ready for wiring (wiring direc-
tions enclosed).
A heavy-duty mercury switch is encapsulated in
the impact -resistant sensor float. Twenty feet of
flexible SJOW-A 16/2 water-resistant cable pro-
trudes from the float housing. Attached to this cord
is a 2 lb. adjustable external weight.
Applications: Common applications include lift
pump chambers, sump pump basins, holding tank
sewage systems, irrigation systems, and other non -
potable water, systems.
Additional Features: When float reaches the alarm
level (activating horn and light), pushing the horn-
ilence.button will silence the horn. The flashing
-ht remains on until the float returns to a non -
arm level. Once the float reaches a non -alarm
revel, the horn automatically resets and is ready to
sound again if another alarm condition should
occur.

This system is designed to provide maximum ultraviolet dosage using low-pressure high output
lamp technology at peak flow at end of lamp life. System has been designed based on
mathematical calculations as outlined in the EPA design manual.
The system will provide > 40,000 uWs/cm2 at peak flow at end of lamp life.
System is proposed with a stainless steel channel with a fixed level control weir.
The system will be provided with transition box connections with 6" or 4" pipe stubs.

Module(s) will hold lamps in a horizontal position in a channel. Lamps will be parallel to the
effluent flow.
The modules will be connected to a remote stainless steel NEMA 4X Power Control Center
(PCC) through watertight cables. The PCC will contain L.E.D. lamp on/off indicators, optional
UV monitoring, elapsed running time meter, on/off switch, electronic ballasts and other electrical
controls. All electrical components will be outside of the channel (no electronics will be
placed in or near the flow).
A fixed serpentine weir will control the effluent level. The weir will force the effluent to stay in
contact with the lamps and expose the effluent to the maximum UV dose. Weir is included in
our scope.
All materials exposed to the effluent will be stainless steel and quartz. All other materials
exposed to UV light will be stainless steel, GE type 214 quartz, Teflon, Viton, EPDM and EPR.
MAINTENANCE
In order to insure proper disinfection, the system needs to be maintained, The UV system has
lamps that are protected by quartz sleeves. The quartz sleeves can become fouled by the solids
in the effluent. This necessitates a cleaning regime that will be determined by plant operating
conditions.
In this project, to clean the sleeves: you have the following options:
Manuel Cleaning
Plant operators can remove a module and clean by hand. A mild citric acid or a lime
removal product can be used to hand -clean the sleeves. If this is the method of choice,
a cleaning rack can be provided. This can be a wall. mounted or free standing stainless
steel support.

The basic system comes standard with analog displays. For greater system control and
monitoring, Sunlight Systems can provide the following:
UV Monitoring
A sensor will monitor a single lamp in each bank of the channel. The relative intensity of
that lamp will be displayed on an analog meter reading 1 to 100%. A low to no UV
reading may indicate that the lamp intensity has fallen, the quartz sleeve is fouled, the
transmission of the effluent has changed or that there is problem with a system
component.

SUBJECT: Engineer's Certification — Completion of Construction
Mount Pleasant High School Wastewater Treatment P �i i �e TSECT ON.
Cabarrus County Schools, Owner
Laughlin — Sutton Construction Company, Contractor
Authorization to Construct Number 077704A01
The enclosed documents contain the Engineer's Certification concerning
completion of construction of improvements at MPHSWWTP. This certification is
required by the ATC prior to diverting flow through the completed improvements for
final discharge. It is the opinion of the Engineer that the completed improvements stand
ready to begin receiving treated effluent from the existing treatment plant. The new
components (pump control panel, dual pumps, air diffiisers, and ultra -violet disinfection
equipment) were turned on, inspected, observed for a time, then switched off, using clean
water added to the new dosing tank during the observation period. It is the opinion of the
engineer that the system stands ready to be placed into operation as soon as the operator
and school maintenance personnel are ready to divert the treated effluent into the new
facilities.
Please let me know if you have any questions, or if I can be of additional service
to you.

Addition of a 8,000 gallon dosing tank, recirculating sand filter (26.67'x 60.0'),
an ultraviolet disinfection system, and all associated appurtenances in conformity

Please be advised that the construction of the proposed improvements has been substantially completed;
that the system has been inspected, tested, and approved by the engineer; that the improvements are
considered to be basically completed. It is the opinion of the engineer that the improvements are ready to
begin receiving treated effluent from the existing wastewater treatment plant, with the flow likely to be
diverted through the new improvements sometime next week. Once the flow is diverted into the completed
improvements, the tablet chlorinator will be removed, the dechlorination feed system will be removed, and
the contents of the existing chlorine contact tank will be pumped out and disposed of properly.
Please be advised that the Contractor, Laughlin — Sutton Construction Company of Greensboro, N.C., still
has items of work remaining to be completed as related to this project, and that another few weeks may be
required by the Contractor, in order to complete all work on this contract. The engineer plans to provide a
subsequent engineer's certification at the time the Contractor has completed all his work on this project.

STEPS FOR CONSTRUCTING RECIRCULATING SAND FILTER SYSTEM AT
MOUNT PLEASANT HIGH SCHOOL WASTEWATER TREATMENT PLANT
WALKER ROAD, CABARRUS COUNTY, NORTH CAROLINA
1. Reroute the existing potable water line and yard hydrant out of the area intended to
accommodate the sand filter bed. Remove the existing wood posts and woven wire
fencing from the area to accommodate the sand filter bed. Lay out the boundary of the
sand filter bed, as well as the boundary of the backfill area around the sand filter bed, on
the site at per engineering plans. The sand filter bed shall be 20 feet wide and 60 feet long
minimum, and the backfill area shall accommodate a backfill slope of 2.5:1.
2. Remove existing sod from the area of the sand filter bed, and store the sod on site for
future reuse. Excavate the area for the floor of the sand filter bed to elevations required
by engineering plans. The floor shall slope 8" from the highest corner of the sand filter
bed floor to the outlet piping to be located at the lowest corned of the sand filter floor.
3. Form the support walls of the sand filter bed using 4' by 8' sheets of thick C-D
plywood and 4x4 wood posts for support set at 8 feet at center or as required around the
perimeter of the sand filter bed at plywood joints.
4. Be prepared to backfill around the exterior of the plywood walls using suitable soils
materials placed in appropriate layers as the materials of the sand filter bed are being
placed inside the plywood walls.
5. Install 30 mil polyethylene or PVC membrane across the floor of the sand filter bed
and extend up the plywood walls to the top of the wall. Install membrane as a single piece
without seams, or provide watertight seams as per manufacturer's recommendations. Be
sure that no punctures of the membrane occur during installation of the sand filter bed.
The only source of water movement through the membrane on the floor of the sand filter
bed shall be through the outlet pipe at the low corner of the sand filter bed.
6. Place 4" diameter porous plastic tubing on top of the membrane across the floor of the
sand filter bed at locations as shown on engineering plans, and use ells, tees and
connector as may be required for a complete and first class installation. Connect tubing to
air ventilation/monitoring ports to be located as shown on engineering plans, and extend
4" diameter Schedule 40 PVC vertical piping, from the tubing at the floor to an adaptor
and removable cap to be located at the top of the sand filter. Provide venting ports in said
vertical piping using '/4" orifices drilled into the pipe at 2" on center around the
circumference of the pipe and along its length from the floor of the sand filter bed to
within 2" of the top of the pipe near its cleanout. Connect the tubing at the low corned of
the sand filter bed to 4" diameter Schedule 40 PVC piping to penetrate through the
plywood wall framing material and through the membrane material, to exit the sand filter
bed. Lay exit pipe at 'slope required by engineering plans. Penetrate the membrane with
watertight connection as recommended by the membrane manufacturer.

STEPS FOR CONSTRUCTION AT MOUNT PLEASANT HIGH SCHOOL
7. Place #5 washed stone on top of the membrane, around the tubing, and across the floor
on the sand filter, to a minimum depth of 8". Spread to a smooth and uniform surface,
ready to receive the next layer of construction of the sand filter.
8. Place clean ornamental pea gravel on top of the layer of #5 washed stone to a
minimum depth of 4". Spread to a smooth and uniform surface, ready to receive the next
layer of construction of the sand filter.
9. Place clean approved filtering sand on top of the layer of ornamental pea gravel, to a
minimum depth of 24' at the high corner of the floor of the sand filter bed, and to a
minimum depth of 32" at the low corner of the floor of the sand filter bed at the outlet
piping. The sand must meet the specifications for filtering sand as established by the
North Carolina Division of Water Quality. The sand shall exhibit an effective size of 0.8
to 1.0 mm and shall contain less than 0.5 percent dust content. The sand supplier shall
verify approval of their sand for use in sand filter beds by submitting a copy of a letter
from the North Carolina Division of Water Quality granting their approval of said sand
during the three-month period prior to the date that sand is delivered to the jobsite for this
project. Spread sand to a smooth, uniform and level surface, ready to receive the next
layer of construction of the sand filter.

Module(s) will hold lamps in a horizontal position in a channel. Lamps will be parallel to the
effluent flow.
The modules will be connected to a remote stainless steel NEMA 4X Power Control Center
(PCC) through watertight cables. The PCC will contain L.E.D. lamp on/off indicators, optional
UV monitoring, elapsed running time meter, on/off switch, electronic ballasts and' other electrical
controls. All electrical components will be outside of the channel (no electronics will be
placed in or near the flow).
A fixed serpentine weir will control the effluent level. The weir will force the effluent to stay in
contact with the lamps and expose the effluent to the maximum UV dose. Weir is included in
our scope.
All materials exposed to the effluent will be stainless steel and quartz. All other materials
exposed to UV light will be stainless steel, GE type 214 quartz, Teflon, Viton, EPDM and EPR.
MAINTENANCE
In order to insure proper disinfection, the system needs to be maintained. The UV system has
lamps that are protected by quartz sleeves. The quartz sleeves can become fouled by the solids
in the effluent. This necessitates a cleaning regime that will be determined by plant operating
conditions.
In this project, to clean the sleeves: you have the following options:
Manual Cleaning
Plant operators can remove a module and clean by hand. A mild citric acid or a lime
removal product can be used to hand -clean the sleeves. If this is the method of choice,
a cleaning rack can be provided. This can be a wall mounted or free standing stainless
steel support.

monitoring, Sunlight Systems can provide the following:
UV Monitoring
A sensor will monitor a single lamp in each bank of the channel. The relative intensity of
that lamp will be displayed on an analog meter reading 1 to 100%. A low to no UV
reading may indicate that the lamp intensity has fallen, the quartz sleeve is fouled, the

Dear Mr. Goodrich:

The Mount Pleasant High School and its wastewater treatment plant were
constructed in 1991, with the wastewater treatment plant being designed by David A.
Roberts, P.E. of Landis, N.C., for discharge into Adams Creek in the Yadldn-Pee Dee
River Basin. The wastewater treatment plant consists of a comminutor, flow equalization
basin with dual effluent pumps, flow splitter box, dual aeration basins with clarifier,
sludge holding tank, tablet chlorination equipment and chlorine contact tank. The plant
was originally designed for the future addition of another pump tank with effluent pump
and sand filter bed as may be needed later for permit compliance, as well as the future
addition of flow monitoring equipment into an existing manhole located downslope of the
chlorination tank. At present, there are no requirements for flow metering for this
discharge.
The wastewater treatment plant is operating under NPDES Permit Number
NCO077704, was designed for capacity of 12,000 gallons per day, and is currently being
operated under contract with the Water and Sewer Authority of Cabarrus County, .
(WSACC). The plant has been operating in compliance with the current limits set by the
NPDES permit. Our goal is to look for improved operation of the existing wastewater
treatment plant for nitrogen reduction.
NPDES Permit Number NCO077704 was reissued on October 29, 2003, with an
effective date of December 1, 2003, and includes two new effluent parameters: Ammonia
--Nitrogen (NH-3), with effective date of 04101/2005; and Total Residual Chlorine, with
effective date of 06/01/2005. The new NPDES Permit does not mandate any construction
changes to the existing wastewater treatment plant, only compliance with these new
effluent limits by the dates identified in the permit.

In an effort to assure compliance with the new effluent limitations, Cabarrus
County Schools has employed the services of David A. Roberts, P.E., the engineer who
designed the original wastewater treatment plant at Mount Pleasant High School, to work
in conjunction with Van Rowell, P.E., on the staff of the Water and Sewer Authority of
Cabarrus County (WSACC). Their goal is to look closely at the current method of
operation of the wastewater treatment plant, and determine if the plant can be operated in
an improved fashion in compliance with the new effluent limits, without requiring major
capital improvements to the existing wastewater treatment plant, or, if not, to recommend
the extent of capital improvements that will be needed in order to operate in compliance
with the new effluent limitations.
The engineer's preliminary investigation has revealed that adjustments of flow
rates from the pumps in the flow equalization basin, through the flow splitter box, to the
two aeration basins, will provide slower and more steady flow to the aeration basins, and
should improve the nitrification process so as to comply with the new NH-3 limits.
Recommendations have been made for the installation of a flow totalizing meter in order
to better understand the daily wastewater flow rates passing through the treatment plant.
Further, it is recommended that the engineers conduct hands -ors evaluation of daily plant
operation; and look at the results of laboratory analysis of plant effluent as adjustments
are made in the day -today operation of the plant. It is recommended that a more frequent
analysis of the discharge be conducted during the time period of April 1, 2004 through
October 31, 2004, looking closely at plant operation and laboratory results, in order to
determine whether or not capital improvements will be needed at this wastewater
treatment plant in order to assure compliance with the new permit limits.
In the event that capital improvements to the wastewater treatment plant become
necessary, engineering plans and specifications for the needed improvements could be
completed by January 1, 2005, and submitted by that date to the Division of Water
Quality for their review, and an ".Authorization to Construct" could be issued by March
15, 2005. The pmject could be advertised for bids by March 20, 2005, with bids received
by April 15, 2005, and construction could begin as early as May 1, 2005. The completion
of all improvements could be accomplished by August 1, 2005, with the plant being
placed into operation at that date. This timeline may require the extension of the time for
compliance with the new effluent limitations until September or October of 2005, to give
the operator sufficient time to get the improved facility into proper operation.
Based upon the information contained in this letter, Cabarrus County Schools
hereby request your approval for the following items of activity and the requested
timeline related to each item:

Dear Mr. Goodrich:
PAGE 07
As outlined in our letter to you dated March 31, 2004 (attached), historical data was provided
concerning the Mount Pleasant High School wastewater treatment plant (WWTP). The letter also
outlined a strategy for conducting an operations study to determine if WWTP could be operated
so as to be in compliance with the new permit limits for Ammonia -Nitrogen (NH-3), without
]laving to implement major capital improvements.. In your response letter dated May 26, 2004
(attached), .concurrence was given to proceed with the four requested action steps that were
presented. Also, the date for compliance with the new effluent ammonia limits was extended
until 10/31/2005. This allowed additional time to determine if it was necessary to undertake
major capital improvements to the WWTP in order to comply with the new effluent ammonia
limits.
Since the date of your letter, we have been conducting the WWTP operations study, which
include the evaluation of different WWTP process wastewater samples to determine how
periodic adjustments in daily operation affect the quality of treatment, all in an effort to
determine if the plant can be operated in compliance with the new ammonia effluent limits,
utilizing the existing process treatment components. The study began in April of 2004, continued
until October 31, 2004, and continues at the present time. During the evaluation period, flow
gates from the flow equalization tank to the two aeration. basins (flows through the flow splitter
box) were adjusted to a much slower rate, with the aeration basins receiving steady flows
throughout most of each school day, and resulting in improvement in the level of treatment. A
chemical feed pump was also added and began feeding a solution of 25% caustic to the flow
equalization tank in an effort to improve the nitrification pmcess. As Changes were being made
to the daily operation of the WWTP, we evaluated the laboratory analysis to see the effect that
those changes,had on the level of treatment. The changes in plant operation have improved the
treatment process, however, it does not appear that the existing plant can be operated on a day-
by-day basis in consistent compliance with the new effluent ammonia limits. Plans are to
continue making periodic adjustments in WWTP operation, particularly adjusting the 25%
caustic feed rate to the flow equalization tank, in an effort to establish the proper

balance that will result in maximizing the process and in allowing the WWTP to operate
consistently in compliance with the new effluent ammonia limits.
Since the new permit requirements do not mandate construction improvements to the existing
wastewater treatment plant, only compliance with the new limits, we have prepared engineering
plans and specification for making improvements to the existing plant. Enclosed are five sets of
the plans and specifications for your review and consideration. It is requested that an
"Authorization to Construct" be issued to Cabarrus County Schools for the work shown on the
submitted plans and specifications. Plans are to initiate the proposed improvements to the
existing WWTP during the summer of 2005, since the operations study has demonstrated that the
existing WWTP cannot consistently meet the new effluent permit limits. The proposed
improvements include installation of ultraviolet disinfection equipment, along with the
abandonment of the existing tablet chlorination equipment and the existing chlorine contact tank.
Plan are to install the ultraviolet disinfection equipment as Phase #1 of the improvements, with
construction of the recirculating dosing tank and sand filter to follow as Phase #2 of the
improvements.
Since chlorine will be discontinued as a disinfectant, it is requested that the Total Residual
Chlorine limit established for this plant be eliminated from the permit requirements, effective
upon completion of installation of the ultraviolet disinfection equipment.
The proposed improvements to the existing Mount Pleasant High School Wastewater Treatment
Plant, as shown on engineering plans, include the following: (a) rearrangement and reworking of
the existing chain link fence around the existing treatment plant to accommodate the proposed
changes; (b) excavation for and installation of a new 81000 gallon precast concrete recirculating
dosing tank with access riser and hatch, and with dual submersible effluent pumps, float control
switches, duplex pump control panel with alarm feature, and independent alarm panel, along
with related piping and electrical accessories; (c) excavation for and construction of a 20' x 60'
lined sand filter bed with underdrain piping system at its bottom and distribution piping system
across its top; (d) furnish and install a "flow divider and valve box" containing three flow
dividers and four valves, for the operator's use in directing portions of the flow back to the
dosing tank for recirculation purposes; and (e) furnishing and installing a "disinfection
equipment well" near the existing manhole down slope of the existing chlorination, contact tank
to be abandoned and replaced by the installation of new ultraviolet disinfection equipment, with
all electrical connection, control panel and accessories.

Permit NCO077704
A. (2.) TEMPORARY MEANS OF DISINFECTION
-In the event that the wastewater treatment plant's ultraviolet (UV) disinfection system should fail,
underperform, or otherwise be removed from effective service, the'permittee or his agent should
immediately inform the Surface Water Protection Section staff of the Mooresville Regional Office of
this development and discuss temporary, alternate means for disinfection of the effluent.
If chlorine compounds are used as temporary means of disinfection, the total residual chlorine (TRC)
concentration of the effluent must be -monitored on a daily basis while this method of disinfection is in
-use and values must be reported on the d scharge. monitoring report. TRC.in the effluent may not exceed
28 µg/L; therefore,. dechlorination methods may also be necessary to ensure protection of water quality
-in the receiving stream.
The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance with the.
permit.. However, the Permittee shall continue..to record and submit all values reported by a North..
.Carolina certified laboratory. (including field certified); even.if these values fall below 50 jig/L.
Use of a disinfection system other than the permitted UV system during circumstances not.deemed as
emergency and/or temporary (replacement of lamps, lamp cleaning or maintenarice, etc.) will be
considered a violation of the terms of this permit. -
