Dear Mr. Jones:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant
to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
This final permit contains no significant changes to its terms from those found in the draft permit sent to
you on May 6, 2015. However, you are also reminded of the new condition requiring electronic
reporting of discharge monitoring report (DMR) data using the Division's eDMR internet application.
This new requirement will become effective on May 1, 2016 (approximately 270 days or nine months
following the effective date of the permit).
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless
such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or any
other Federal, State, or Local governmental permits that may be required.

Permit NCO028711
A. (2.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Reporting
Records Retention
Monitoring Reports
1. Reportiniz [Supersedes Section D. (2.) and Section E. (5.) (a)]
Beginning no later than May 1, 2016 (270 days from the effective date of this permit), the
permittee shall begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DENR / DWR / Information Processing_ Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1,
2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to
the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.

A. (2.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS, continued
Information on eDMR and application for a temporary waiver from the NPDES electronic
reporting requirements is found on the following web page:
http://Portal.nedenr.org/web/w�
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B (11) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part
II, Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (I 1.)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit
the following web page:
http'//portal ncdenr or web/wq/admin/bo i u/edmr

make the following certification [40 CFR 122.221. NO OTHER STATEMENTS OF
CERTIFICATION WILL BE ACCEPTED:
V certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and belief, true, accurate,
and complete. I am aware that there are significant penalties for submitting false information,
including the possibility offines and imprisonment for knowing violations,"
3. Records Retention [Supplements Section 1). (6.)1
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions.
These records or copies shall be maintained for a period of at least 3 years from the date of the report. This
period may be extended by request of the Director at any time [40 CFR 122.41].

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be
representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which is
not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder -and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or
Version 11/09/2011.1

NPDES Permit Standard Conditions
Page 2 of 18
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.

grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).

Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered =1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).

Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA.
Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.
Monthly Average (concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform or other bacterial parameters or indicators, the geometric mean of such discharges.

Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Simificant Industrial User" or "S1U"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H

coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which is
not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or
Version 1110912011

NPDES Permit Standard Conditions

(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).

Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).

Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H

noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.
Section B. Publicly Owned Treatment Works (POTWs)
Version 1110912011

NPDES Permit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:

Dear Mr. Berry:
Dewberry Engineers Inc. (Dewberry) is providing this letter and attachment for the Engineer's
Certification for the above referenced project. With completion of the improvements permitted by the
above referenced Authorization to Construct, the Berryhill Elementary School WWTP now has a
permitted capacity of .008 MGD as authorized by NPDES Permit No. NCo028711. The updated effluent
limits and monitoring requirements approved in the NPDES permit modification (April 11, 2012) will
become effective with this Engineer's Certification.
The attached Engineer's Certification notes three minor changes from those approved by the
Authorization to Construct. Two tube chlorination and dechlorination tablet feed systems were installed
instead of the three tube chlorination and dechlorination tablet feed systems that were approved.
Additionally, a submersible pump was provided in the sludge holding tank instead of the submersible
grinder pump which was approved. These changes should not impact the performance of the WWTP.
Should you have any questions or comments concerning this submittal, please do not hesitate to call me at
[phone] or email me at [e-mail].

Subject: FW:
Michael,
This forwarded email is the email response I sent to the consultant we discussed. Mr. West called the next day to discuss
this email, his parting comment was he needed to confer with the owner to determine what his next steps would be.
He did request a spec letter which I told him we could not issue as this discharge is not a POTW facility. But I would as
part of the formal permitting modification process provide a preliminary copy of the draft for his review prior to issuing
a draft for public comment. This would allow the permittee an opportunity to discontinue the modification request if
necessary. I also pointed out the expanded permit would have more stringent limits (current discharge is into Lake
Wylie). Several additional comments were provide to help direct the consultant in to what minimum items should be in
the required EAA.
One of the first items I need is upon receipt by the region of the modification application is to review the application
and indicate either its support or it has issues with the modification request.
Let me know if you have any questions or concerns.

Subject: NCDENR response for NPDES permit modification for Berryhill Elementary School
Mr. West:
The Division has reviewed your July 6, 2011 letter, Berryhill Flementary School NPDFS permit modification
request, and has determined that this is a major permit modification. The proper NPDES application must be completed
and submitted, in this case NC Form D. Also, since you requested increasing the permitted discharge an EAA must be
submitted in conjunction with the application. Three copies of all submitted documents are required. The $260 fee was
appropriate for the NPDES modification.
The active NPDES permit has an assigned waste load allocation which cannot be exceeded thus, impacting the
effluent limits that will apply for the increased flow. This may further impact your calculation for the rerate.

As you noted , the rerate and subsequent equipment changes will require completion and submittal of an 'R
Authorization to Construct (A to C) application to the Construction Grants & Loans Section for approval. You cannot
submit the A to C application until a modified NPDES permit has been issued.
All of this information, guidance, and forms are available on our web site:

Dewberry Project # 50046144
Dear Mr. Sledge:
As discussed in our phone conversation on May 2, 2011, Dewberry & Davis, Inc. (Dewberry) is submitting
this letter for your review to request a modification to the Berryhill Elementary School National
Pollutant Discharge Elimination Permit (NPDES). The requested modification is to increase the average
daily discharge from 6,000 gallons/day (GPD) to 8,000 GPD. This modification to the NPDES permit is
being requested as there is no public sanitary sewer service available in this area and no plans to provide
sanitary sewer are currently being considered. It is our understanding that major modification to this
minor NPDES permit will be required.
Charlotte Mecklenburg Schools (CMS) operates a wastewater treatment plant (WWTP) at Berryhill
Elementary School currently permitted for average daily discharge of 6,000 GPD under National
Pollutant Discharge Elimination System (NPDES) permit NC0028711. The WWTP discharges to the
Catawba River (Lake Wylie), subbasin 30084. Dewberry has performed a feasibility study that evaluated
the current WWTP capacity and options for expansion. Based on the feasibility study it appears that the
WWTP processes and equipment may be adequately sized and that the average daily flow can be
reliably increased to 8,000 GPD based on the hydraulic loading with only minor modifications to the
WWTP. To confirm the results of the feasibility study, CMS has obtained four composite samples of the
influent waste stream. A summary of these samples of the influent waste stream is provided in Table 1
below.

The results of the influent waste stream sampling showed that the influent waste was higher strength
than was assumed in the feasibility study. If the NC Division of Water Quality (DWQ) determines that
the average daily flow can be increased to 8,000 GPD, the WWTP will again be evaluated to determine if
it can meet the discharge limits set forth for the increase flow.
A summary of the daily monitoring reports (DMRs) for the period of January 2009 -January 2011 is
provided below. This information is being included to provide DWQ with pertinent information about
the operation and treatment abilities of the WWTP in its current state. Table 2 provides the parameters
monitored under the permit and the results based on the current operation. The minimum, average,

Based on the summary of the DMRs you can see that the WWTP currently permitted for an average daily
discharge of 6,000 GPD reliably meets the limits set forth in the current NPDES permit. While there are
some exceedances, both minimum and maximum of the permit limits, these events occurred only once
and were rectified on the following day.
A summary of the processes and equipment based on the general design criteria at a flow of 8,000 GPD
is provided in the Table 2 below. The WWTP is a package type extended aeration facility. It includes an

the general design criteria at a flow of 8,000 GPD is provided in the Table 2 below. A detailed analysis of
each process in included in the feasibility study in Attachment A.

Based on this analysis, the current WWTP is designed to handle flows in excess of 6,000 GPD.
Additionally, the current WWTP may be able to handle flows of 8,000 GPD with minor modifications.
CMS plans to make the modifications mentioned below and will submit a request for an Authorization to
Construct (A to C) to the Construction Grants and Loads Section (CG&L) after the draft NPDES permit is
issued for a modified flow of 8,000 GPD if it is determine the WWTP can meet the limits set forth in the
draft permit. These modifications included the following:
1. Sandblast and repaint the exterior walls of the WWTP. Drain, inspect and determine if
coating the interior walls of the WWTP below normal water level is required.
2. Provide a monitoring manhole near the fence on the effluent outfall to Lake Wylie.
3. Replace the RAS pump with a "geyser" type pump to provide a more efficient and reliable
transfer of sludge to the sludge holding basin. This will in turn produce a lower average
total solids loading to the clarifier and improved clarifier performance.

4. Provide an interval timer for the equalization pump with level float override. This will allow
the operator flexibility in operating the WWTP and will keep the plant on a more continuous
operating cycle for more desirable continuous "feeding" of active biomass.
5. Potentially increase the size of the aeration basin if required to meet the limits set forth in
the draft permit for an average daily flow of 8,000 GPD.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall
be representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
B ass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which
is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
• with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
Version 712009

NPDES Permit Standard Conditions

totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. Use of this method requires prior approval by the Director. This method
may only be used in situations where effluent flow rates vary less than 15 percent. The following
restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent
grab samples at intervals of no greater than 20 minutes apart during any 24-hour period.

effluent grab samples at least every six hours; there must be a minimum of four samples during a 24-hour
sampling period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.2)

e. Possible toxic impacts to surface waters: Chlorine is added to the waste stream,
however, dechlorination is provided.
2. Compliance Background: This facility has maintained a generally good compliance
history with only a few record keeping deficiencies noted in the past few years. A CEI
was performed at this facility on November 17, 2009, by MRO and MCWQP staff, and
with the exception of a few minor deficiencies, the WWTP was in excellent operational
condition.
PART III - OTHER PERTINENT INFORMATION
Special monitoring or limitations (including toxicity) requests: None at this time.
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee (Charlotte -Mecklenburg Schools) has requested renewal of the subject
permit. There have been no changes to the permit nor the WWTP since the permit was last
renewed nor are any proposed during this renewal. At one time there was some discussions
between the school system and Charlotte -Mecklenburg Utilities to end sewer service to this area
and eliminate the existing discharge. At the present time, there are no plans to serve this area
with sewer, therefore, continued operation of the WWTP will be necessary.
Pending a final review by the NPDES Unit, it is recommended the permit be renewed as
requested.

Reference: Request for Authorization to Construct
Charlotte Mecklenburg Schools - Berryhill Elementary School WWTP
Dewberry Project # 50o64927
Dear Mr. Berry:
Dewberry Engineers Inc. (Dewberry) is pleased to submit this Authorization to Construct (ATC) request
for the following proposed project at the existing wastewater treatment plant (WWTP) located at the
Berryhill Elementary School in Charlotte, NC. Charlotte Mecklenburg Schools currently operates a .006
MGD wastewater treatment plant under NDPES Permit # NCo028711. The purpose of the project is to
modify the existing plant and install a new septic sludge holding tank to increase treatment capacity to
0.008 MGD. A modified NPDES permit to reflect this capacity expansion has been approved by NCDENR
and is included with this application package. An Authorization to Construct was previously issued for
this project (A to C No. 028711Ao2). However, the design has since been modified such that the existing A
to C does not accurately reflect the proposed work. We request that the existing A to C be cancelled as part
of this application review.
Charlotte Mecklenburg Schools plans to begin construction in May of 2014.
As part of this ATC request we are submitting one (1) original and one (1) digital copy of the following
items for review:
• Authorization to Construct application form,
• Signed and sealed plans,
• Signed and sealed technical specifications,
• Signed and sealed calculations, and
• The NPDES permit current held by the facility.
Should you have any questions or comments concerning this submittal, please do not hesitate to call me at
[phone] or email me at [e-mail].
Sincerely,

Dewberry & Davis, Inc. (Dewberry) has received and reviewed you comments dated April 5, 2012 related
to the above referenced project. Responses to these comments are provided below. Please note that
the dual sludge holding tanks each have a capacity of 4,000 gallons, not 3,500 gallons.
(1) Sheets C2 and C4
(a) It is not clear why there is a proposed (2-inch) pipe from the EQ pump (inside equalization
holding basin) to the proposed dual 3,500 gallon sludge holding tanks. What is this to be
used for?
Response: The 2-inch pipe from the EQ pump discharge to the dual 4,000 gallons sludge
holding tanks is proposed for operational flexibility in the event of an
emergency. An emergency would be defined a toilet valve hanging open within
the school or a similar event. If the EQ tank were to begin to reach the overflow
pipe, wastewater in the EQ tank could be temporarily diverted to the sludge
holding tanks if sufficient capacity exists. The sludge supernatant pumps would
be used to pump the wastewater back to the EQ tank or the dual 4,000 gallon
sludge holding tanks would be pumped and the contents disposed of at a POTW.
(b) At the top of the sheet, a note states that there will remain an existing 6-inch overflow pipe
from the EQ basin to the expanded aeration basin, and to see a detail on Sheet C4.
However, there is no detail on Sheet C4 about this.
Response: The note on sheet C2 referencing a detail on sheet C4 should be removed. This
note is also on sheet C3 and should be removed from this sheet as well.
The existing 6-inch overflow pipe will not be impacted by the addition of the
window to the wall between the EQ basin and the existing sludge holding
basin/expanded aeration basin.

(2) Regarding the proposed dual 3,500 gallon sludge holding septic tanks:
(a) It appears that the two 3,500 gallon sludge holding septic tanks do not have diffused air
provided to them. Please discuss if air is needed to eliminate septic conditions in the sludge.
Response: The dual 4,000 sludge holding tanks do not have diffused air provided to them.
It is anticipated that the dual 4,000 sludge holding tanks will operate in an
anaerobic/septic manner. Due to the relatively small amounts of sludge
supernatant that will be returned to the EQ basin, adequate amounts of diffused
air are present in the EQ basin to reaerate the sludge supernatant and maintain
aerobic conditions in the EQ basin.
(b) We wonder if there may be value in having a deeper septic tank (more than about 5-foot
working depth) to allow more settling of sludge at the bottom. 5-feet appears somewhat
shallow.
Response: The intent is for the wasted sludge to separate and settle within the dual 4,000
gallon sludge holding tanks. Compactive settling and sludge thickening of the
wasted sludge is not intended or proposed. Additionally, the additional costs
associated with a deeper sludge holding tank will exceed the minimum benefits
realized for compactive settling and sludge thickening within a deeper sludge
holding tank. Therefore, we do not believe that a working depth of greater than
5-feet is needed.
(3) Regarding the proposed UV disinfection system:
(a) Normally we require effluent filtering (e.g., sand filters, etc) prior to utilizing UV disinfection.
Please justify the usage of UV disinfection (in this case) without the use of filters.
Response: Past performance of this wastewater treatment plant indicates low Total
Suspended Solids (TSS) and a high quality effluent. The average TSS value for the
period August 2008 through June 2011 is 8.08 mg/L. Additionally, Dewberry has
designed multiple wastewater treatment plants that are operating UV
disinfection systems without tertiary filtration. Due to these facts, we believe
that tertiary filtration prior to the UV disinfection system is not needed for this
wastewater treatment plant.
(b) The specifications (Section 1330, Part 2.10) for the UV disinfection system should include UV
energy density specifications at a particular wastewater TSS and UV transmittance.
Response: Specification section 13300, Part 2.10 has been updated. Part 2.10 will be
replaced with the following:

"2.10 The UV system shall be housed in a 4" ABS pipe suitable for a direct bury
installation. 4" ABS inlet and outlet couplings shall be provided. The
disinfection chamber shall be located below the inlet and outlet
couplings. The UV subassembly shall fit inside the housing. The UV
subassembly shall contain an anodized aluminum frame, a UV lamp, a
quartz sleeve, and a teflon sheath. Each unit of the UV system shall be
rated for a forward flow rate of at least 6 gallons/minute. The UV
system shall contain a control enclosure and mounting bracket both of
which are located above grade. The UV disinfection system shall be
capable of producing greater than 30,000 microwatt-seconds per square
centimeter at the end of lamp life and be capable of disinfecting the
peak flow rate of 32,000 gallons per day to a standard of 200 fecal
coliforms per 100 ml of effluent based on a geometric mean of daily
samples and a total suspended solids (TSS) of 10 mg/L. An electrical
disconnect switch shall be located adjacent to the UV system."
(c) Please indicate if there is sufficient driving head to overcome any headloss through the UV
system.
Response: Sufficient driving head exists to overcome any headlosses that may be
experienced through the UV disinfection system. Calculations are included with
this comment response letter.
During the submittal phase of this project, the UV disinfection system proposed
by the successful Contractor will be evaluated to ensure sufficient driving head
exists to overcome any headlosses regardless of the UV disinfection system
provided. Also, please note that he UV disinfection system is being bid as an
alternate bid item and may or may not be awarded.
(d) From Sheet C2, we assume from Sheet C2 that the UV system is piped in just prior to the
Tablet Chlorination System, such that if the UV system power is turned off, the ORC
operator can still use the tablet chlor/dechlor system. Please confirm this.
Response: Two 4-inch plug valves are noted on sheet C2 and are located on piping leaving
the post aeration tank. If the UV disinfection system is operating, the 4-inch
plug valve located closest to the tablet feed chlorination system will be closed
and the 4-inch plug valve closest to the UV disinfection system will be open
routing wastewater through the UV disinfection system. If the UV disinfection
system is not operational or loses power, the 4-inch plug valve closed to the UV
disinfection system will be closed and the 4-inch plug valve closed to the tablet
feed chlorination system will be open routing wastewater through the tablet
feed chlorination system. The operator can use the tablet feed
chlorination/dechlorination system if the UV disinfection system is non
operational or loses power.

3. Report prepared by: Michael L. Parker, Environmental Engineer if
4. Person contacted and telephone number: Matthew West, [phone]
5. Directions to site: From the jct. of Old Dowd Road and Walkers Ferry Road in western
Mecklenburg County, travel southwest on Walkers Ferry Road z 2.0 miles to the WWTP
site. The plant site is on the left (east) side of the road and on the south side of the school
grounds.
6. Discharge point(s): Latitude: 350 12' 41"
Longitude: 800 59' 56" USGS Quad No.: G15NW
7. Receiving stream or affected surface waters: Lake Wylie
a. Classification: WS-fV, and B
b. River Basin and Subbasin No.: Catawba 030834
C. Describe receiving stream features and pertinent downstream uses: The discharge is
into a cove of Lake Wylie (Paw Creek arm). This area of the lake receives frequent
bodily contact through various water recreational activities. No other downstream
dischargers are known.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
a. Actual treatment capacity: 0.006 MGD (Design Capacity)
b. Current permitted capacity: 0.006 MGD
C. Proposed re -rated capacity: 0.008 MGD

Mal
C. Description of existing or substantially constructed WWT facilities: The existing
WWT facilities consist of a bar screen, a flow equalization basin, an aeration basin,
dual secondary clarifiers with sludge return, an aerated sludge holding tank, chlorine
(tablet) disinfection, and dechlorination.
d. Description of proposed WWT facilities: The proposed modifications to the existing
WWT facilities include the addition of an interval timer for the equalization pump,
the addition of two 3000 gallon capacity septic tanks for use as sludge storage tanks,
rehabilitation of the metal walls of the existing WWTP, and replacement of the RAS
PUMP.
e. Possible toxic impacts to surface waters: Chlorine is added to the waste stream,
however, dechlorination is provided.
2. Compliance Background: This facility has maintained a generally good compliance history
with only a few record keeping deficiencies noted in the past few years. A CEI was
performed at this facility on December 21, 2010, by MCWQP staff, and the WWTP was
found to be in excellent operational condition.
PART III - OTHER PERTINENT INFORMATION
Special monitoring or limitations (including toxicity) requests: None at this time (see Part
IV).
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, Charlotte -Mecklenburg Schools (CMS), has requested that the subject permit
be modified to allow for a re -rating to increase in the permitted capacity from 0.006 MGD to 0.008
MGD. This increase in capacity is necessary in order to accommodate an anticipated increase in
student/faculty enrollment expected for the 2012/2013 school year. CMS's engineering firm has
prepared an Engineering Alternative Analysis (EAA) that evaluates the various disposal alternatives
and ultimately offers supports for the proposed re -rating based on a review of the existing WWT
facilities and the available non -discharge disposal options.
The EAA notes that current well production records at the school reflect an average daily
water usage of 7.5 —11.5 gallons/student, which is still below the 12 gallons/student design flow
used in the EAA preparation. Using a flow rate of 12 gallons/student/day would conservatively
allow for a student/faculty population of approximately 667, which would be expected to generate
the proposed 8000 gallons/day of flow proposed in this re -rating request.
Alternatives evaluated in the EAA include land application and connection to an existing
collection system. The nearest collection system is over 1.5 miles from the school and CMS has
indicated that it would be economically unfeasible given the distance and cost of the infrastructure
necessary to make the connection. The land application option was also discounted given the
availability and anticipated cost of the necessary 13 acres of land needed to assimilate the proposed
8000 gpd of flow.
11

FF
Page Three
Given the familiarity of the RO staff with the existing WWT facilities and the area in and
around Berryhill school, it appears that a re -rating of the existing WWTP can be supported by the
findings and recommendations contained in the EAA. However, conversations with CO staff have
noted the possibility of the current NPDES permit limitations becoming more stringent should the
re -rating request be approved. Any reduction in the current effluent limitations as a result of the re -
rating to 8000 gpd will also necessitate a re-evaluation of the proposed facility modifications as
noted in the EAA. Additional facility changes (including additional treatment components not
proposed in the EAA) may be necessary to comply with the proposed effluent limitations.
Pending a final review by the NPDES Unit and approval of the draft NPDES permit, it is
recommended the permit re -rating request be approved.
