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
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

Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected
and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The
devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements is consistent
with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a
maximum deviation of less than 10% from the true discharge rates throughout the range of expected discharge
volumes. Flow measurement devices shall be accurately calibrated at a minimum of once per year and maintained
to ensure that the accuracy of the measurements is consistent with the accepted capability of that type of device.
The Director shall approve the flow measurement device and monitoring location prior to installation.
Once -through condenser cooling water flow monitored by pump logs, or pump hour meters as specified in Part I of
this permit and based on the manufacturer's pump curves shall not be subject to this requirement.
4. Test Procedures
Laboratories used for sample analysis must be certified by the Division. Permittees should contact the Division's
Laboratory Certification Section (919 733-3908 or http://portal.ncdenr.org/web/wq/lab/cert) for information
regarding laboratory certifications.
Facilities whose personnel are conducting testing of field -certified parameters only must hold the appropriate field
parameter laboratory certifications.
Test procedures for the analysis of pollutants shall conform to the EMC regulations (published pursuant to NCGS
143-215.63 et. seq.), the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section
304(g), 33 USC 1314, of the CWA (as amended), and 40 CFR 136; or in the case of sludge use or disposal,
approved under 40 CFR 136, unless otherwise specified in 40 CFR 503, unless other test procedures have been
specified in this permit [40 CFR 122.41].

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 defmition 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
.0903(b)(33)]:

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 defmition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

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.
3/Week
Samples are collected three times per week on three separate calendar days.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, 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 induding 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 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
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
daring any 24-hour period and must be of equal size and of no less than 100 *milliliters. Use of this method
requires prior approval by the Director.

system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four 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)
Daily Maximum
The highest "daily discharge" for conventional and other non -toxicant parameters. NOTE: Permittees may not
submit a "daily average" calculation [for determining compliance with permit limits] for toxicants. See the relevant
Federal effluent guideline[s] for the appropriate calculation intervaL
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit The Division expects that 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).

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

operator in responsible charge:
a Within 60 calendar days prior to wastewater being introduced into a new system
b. Within 120 calendar days of:
> Receiving notification of a change in the classification of the system requiring the designation of a
new ORC and back-up ORC
> A vacancy in the position of ORC or back-up ORC.
2. Proper Operation and Maintenance
The Permittee shall at all times provide the operation and maintenance resources necessary to operate the existing
facilities at optimum efficiency. The Permittee shall at all times properly operate and maintain all facilities and
systems of treatment and control (and related appurtenances) which are installed or used by the Permittee to
achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate
laboratory controls and appropriate quality assurance procedures. This provision requires the Permittee to install
and operate backup or auxiliary facilities only when necessary to achieve compliance with the conditions of the
permit [40 CFR 122.41 (e)].
NOTE: Properly and officially designated operators are fully responsible for all proper operation and
maintenance of the facility, and all documentation required thereof, whether acting as a contract operator
[subcontractor] or a member of the Permittee's staff.
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a Permittee in an enforcement action that it would have been necessary to halt or
reduce the permitted activity in order to maintain compliance with the condition of this permit [40 CFR 122.41
(c)].
4. Bypassing of Treatment Facilities
a. Bypass not exceeding limitations [40 CFR 122.41 (m) (2)]
Version 5/2009

NPDES Permit Standard Conditions
Page 8 of 18

only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the
provisions of Paragraphs b. and c. of this section.
b. Notice [40 CFR 122.41 (m) (3)]
(1) Anticipated bypass. If the Permittee knows in advance of the need for a bypass, it shall submit prior
notice, if possible at least ten days before the date of the bypass; including an evaluation of the
anticipated quality and effect of the bypass.
(2) Unanticipated bypass. The Permittee shall submit notice of an unanticipated bypass as required in Part
I I . E . 6. (24-hour notice).
c. Prohibition of Bypass
(1) Bypass from the treatment facility is prohibited and the Permit Issuing Authority may take enforcement
action against a Permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities,
retention of untreated wastes or maintenance during normal periods of equipment downtime. This
condition is not satisfied if adequate backup equipment should have been installed in the exercise of
reasonable engineering judgment to prevent a bypass which occurred during normal periods of
equipment downtime or preventive maintenance; and
(C) The Permittee submitted notices as required under Paragraph b. of this section.
(2) Bypass from the collection system is prohibited and the Permit Issuing Authority may take enforcement
action against a Permittee for a bypass as provided in any current or future system -wide collection system
permit associated with the treatment facility.
(3) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse effects, if
the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph c.
(1) of this section.
5. Upsets
a Effect of an upset [40 CFR 122.41 (n) (2)]: An upset constitutes an affirmative defense to an action
brought for noncompliance with such technology based permit effluent limitations if the requirements of
paragraph b. of this condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final administrative action
subject to judicial review.
b. Conditions necessaryfor a demonstration of upset: Any Permittee who wishes to establish the
affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or
other relevant evidence that:
(1) An upset occurred and that the Permittee can identify the cause(s) of the upset;
(2) The Perr ittee facility was at the time being properly operated; and
(3) The Permittee submitted notice of the upset as required in Part II. E . 6. (b) of this permit.

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Alcoa Power Generating, Inc., operates a powerhouse (dam) on the Yadkin
River known as the Falls Powerhouse, which generates hydroelectric power. Complex electrical
generation machinery exists at this facility that requires cooling water during operation. In this
modification request, Alcoa plans to construct secondary containment around existing transformers
located at the subject facility. This secondary containment will require the occasional removal of
storm water (SW) that will accumulate in the containment area and ultimately be discharged through
existing SW outfalls.
In lieu of additional monitoring, Alcoa has requested that BMP's be utilized to ascertain
permit compliance. It should be pointed out that these are existing transformers, and any leakage
that may have occurred from these units in the past would have entered the existing SW drainage
without being monitored. This Office has no objection to allowing Alcoa to utilize BMP's in lieu of
additional monitoring, however, it is recommended that the NPDES permit contain a requirement
that any discharges from the secondary containment structure be reported along with the annual
monitoring currently required by the permit.
It is recommended that the NPDES Permit be modified as requested.

POINT SOURCE BRANCH
Alcoa Power Generating, Inc has plans to install secondary containment for transformers which are part of the
substations located at the Falls, Tuckertown, and High Rock Powerhouses. The Narrows Powerhouse does not have
transformers on site and thus will not be installing any containment at this location. The installation of secondary
containment will require the periodic removal of storm water which accumulates in the containment area and
discharge through existing storm water conveyance systems. Historically, the storm water from these substations
has been passively discharged through these same existing storm water conveyance systems.
As per previous conversations regarding this matter, Alcoa Power Generating, Inc would like to request that Best
Management Practices (BMP's) be utilized for permitting these discharges in lieu of monitoring requirements and
associated permit limits. The Best Management Practices that we are proposing would include designing the sumps
with underflow weirs/devices to prevent the discharge of oily water, weekly inspections of the transformers for
leaks / drips of oil, routine preventative maintenance procedures to address any leaks / drips of oil, inspection of
the sump for the presence of oil as indicated by a visible sheen prior to discharging, and maintaining a log to
document the time, date, and volume of water discharged per discharge event.
To this end, please find attached an application to amend the the Falls Powerhouse NPDES permit to include this
discharge, as well as, a check for the permit fee in the amount of $215.00.
If you should have any questions or comments, please don't hesitate to contact me @ 704-422-5774 or Larry

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Alcoa Power Generating, Inc. (formallyYadkin, Inc., a subsidiary of
ALCOA), operates a powerhouse (dam) on the Yadkin River known as Falls Powerhouse, which
until about six months ago generated hydroelectric power that was used in ALCOA's aluminum
manufacturing process. Due to poor economic conditions and the global aluminum market,
ALCOA has since curtailed all manufacturing operations, and the dams are now only used to
produce hydroelectric power that is sold to the local electric utility companies.
issued.
There have been no changes and/or modifications to this facility since the Permit was last
It is recommended that an NPDES Permit be renewed as requested.

The NPDES Unit received your permit renewal application on July 24, 2003. Thank you for
submitting this package.
The permit renewal for this facility has been assigned to Charles Weaver. This staff member will
contact you if further information is needed to complete the permit renewal. Please note that the
NPDES Unit has several vacant positions. This staff shortage has lasted for over 4 years and is
delaying all permit renewals. Our remaining permit writers are currently reviewing Authorizations
to Construct, speculative limit requests, major permit modifications and 201 plan updates ahead of
permit renewals. This is necessary due to a variety of factors, including mandatory deadlines in
the statutes which govern our program.
If this staff shortage delays reissuance of NC0076775 the existing requirements in your permit
will remain in effect until the permit is renewed (or the Division takes other action). We
appreciate your patience and understanding 'while we operate with a severely depleted staff. If
you have any additional questions concerning renewal of the subject permit, please contact
Charles Weaver at [phone], extension 511.

Based on your comments dated December 17, 2003, the Division of Water Quality has modified the Alcoa Power
Generating, Inc. permits. Unfortunately, your comments were submitted after the 30-day comment period and eve
were unable to make corrections in the final permits, so they are being made with this modification.
The reference to Special Condition A(3) Penstock Sump Drains has been removed from Permit NC0081957, and
the date for submitting the first DIM has been changed to January 30, 2005 in the following permits: NC0076775,
NC0081957, NC0081949, NC0081931.
Please find enclosed the revised permit pages. The revised pages should be inserted into your permit. The old pages
may then be discarded. All other terms and conditions contained in the original permits remain unchanged and in
full effect. This permit modification is issued under the requirements of North Carolina General Statutes 143-215.1
and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit modification 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,

Dear Mr. Gross:
Our records indicate that NPDES Permit No. NC0076775 was issued on December 30, 2003
for the discharge of wastewater to the surface waters of the State from your facility. The purpose of
this letter is to advise you of the importance of the Permit and the liabilities in the event of failure -to
comply with the terms and conditions of the Permit. If you have not already dole so, it is suggested
that you thoroughly read the Permit. Of particular importance are Pages 4 and 5.
Pages 4 and 5 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth. The section headed
"Monitoring Requirements" describes the measurement frequencies, sample types and sampling
locations. Upon commencement of your discharge (or operation), you must initiate the required
monitoring. The monitoring results must be entered on reporting forms furnished or approved by
this Agency. If you have not received these forms, they should be arriving shortly. If you fail to
receive the forms, please contact this Office as quickly as possible. "I have enclosed a sample of the
"Effluent" reporting form (DWQ Form MR-1), plus instructions for completing the form. It is
imperative that all applicable parts be completed, and the original and one copy be submitted as
required.
Please be advised that an annual administering and compliance monitoring fee may be
required for your facility. You will soon be receiving a statement from our Raleigh Office. It is
imperative that the fee be paid in a timely manner so as to prevent enforcement action or possible

revocation of your permit.
The remaining parts of the Permit set forth definitions, general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The
conditions include special reporting requirements in the event of noncompliance, bypasses, treatment
unit/process failures, etc. Also addressed are requirements for a certified wastewater treatment plant
operator if you are operating wastewater treatment facilities. Any changes in operation of
wastewater treatment facilities, quantity and type of wastewater being treated or discharged,
expansions and/or upgrading of wastewater treatment facilities must be permitted or approved by this
Agency.
Failure to comply with the terms and conditions of an NPDES Permit subjects the Permittee
to enforcement action pursuant to Section 143-215.6 of the North Carolina General Statutes. A civil
penalty of up to $25,000 per violation (and/or criminal penalties) may be assessed for such
violations. If you find at any time that you are unable to comply with the terms and conditions of the
Permit, you should contact this Office immediately. A Special Order by Consent (SOC) may be
necessary while pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally.issued for a five-year period. Permits are not
automatically renewed. Renewal requests must be submitted. to this Agency no later than 180 days
prior to expiration. Please make note of the expiration date of your Permit.. This date is set forth on
Page 1 of the Permit. Also note that NPDES Permits are not automatically transferable. If you, as
the Permittee, cease to need this -Permit, then you should request that the Division of Water Quality
rescind the Permit .or request that DWQ reissue the Permit to another party, if necessary.
As mentioned previously, the purpose of this letter is to advise you of the importance of your
NPDES Permit. Please read the Permit and contact this Office at 704/663-1699 in Mooresville if
you have any questions or need clarification. We look forward to providing any assistance.

3/Week
Samples are collected three times per week on three separate calendar days.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, 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.

consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
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
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four 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 122.3)
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

> Visit the facility at least daily, excluding weekends and holidays
> Properly manage and document daily operation and maintenance of the facility
> Comply with all other conditions of 15A NCAC 8G.0204.
Once the facility is classified, the Permittee shall submit a letter to the Certification Commission designating the
operator in responsible charge:
a. Within 60 calendar days prior to wastewater being introduced into a new system
Version 6/20/2003

NPDES Permit Requirements
Page 7 of 16
b. Within 120 calendar days of:
➢ Receiving notification of a change in the classification of the system requiring the designation of a
new ORC and back-up ORC
➢ A vacancy in the position of ORC or back-up ORC.
2. Proper Operation and Maintenance
The Permittee shall at all times provide the operation and maintenance resources necessary to operate the existing
facilities at optimum efficiency. The Permittee shall at all times properly operate and maintain all facilities and
systems of treatment and control (and related appurtenances) which are installed or used by the Permittee to
achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate
laboratory controls and appropriate quality assurance procedures. This provision requires the Permittee to install
and operate backup or auxiliary facilities only when necessary to achieve compliance with the conditions of the
permit [40 CFR 122.41 (e)].
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a Permittee in an enforcement action that it would have been necessary to halt or
reduce the permitted activity in order to maintain compliance with the condition of this permit [40 CFR 122.41
(c)].
4. Bypassing of Treatment Facilities
a. Bypass not exceeding limitations [40 CFR 122.41 (m) (2)]
The Permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but
only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the
provisions of Paragraphs b. and c. of this section.
b. Notice [40 CFR 122.41 (m) (3)]
(1) Anticipated bypass. If the Permittee knows in advance of the need for a bypass, it shall submit prior
notice, if possible at least ten days before the date of the bypass; including an evaluation of the
anticipated quality and effect of the bypass.
(2) Unanticipated bypass. The Permittee shall submit notice of an unanticipated bypass as required in Part
II. E. 6. (24-hour notice).
c. Prohibition of Bypass
(1) Bypass from the treatment facility is prohibited and the Permit Issuing Authority may take enforcement
action against a Permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities,
retention of untreated wastes or maintenance during normal periods of equipment downtime. This
condition is not satisfied if adequate backup equipment should have been installed in the exercise of
reasonable engineering judgment to prevent a bypass which occurred during normal periods of
equipment downtime or preventive maintenance; and
(C) The Permittee submitted notices as required under Paragraph b. of this section.
(2) Bypass from the collection system is prohibited and the Permit Issuing Authority may take enforcement
action against a Permittee for a bypass as provided in any current or future system -wide collection system
permit associated with the treatment facility.
(3)
The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse effects, if
the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph c.

SUMMARY
This facility maintains 6 outfalls (001, 002, 003, 004, 005 and 007) With the exception of outfall 007
(sump drain) the source of water for the other outfalls is once through cooling water. The old permit
stipulates that outfalls 001 through 005 monitor (with no limits) flow, temperature and pH. For the
outfall 007 monitoring was required for oil and grease, flow and pH.
The receiving stream, Yadkin River, is classified as WS-IV and B CA waters, from a point 0.6 mile
upstream of the High Rock Lake Dam to the Badin Dam. This reach is not listed on the 303(d) list as
impaired water. According to the March 2003 Yadkin -Pee Dee River Basinwide Water Quality
management Plan this reach has been classed as supporting its designated uses.

Subject: NPDES Permit Modification
Permit No. NC0076775
Falls Powerhouse
Stanly County
Dear Mr. McCaskill:
The Division issued NPDES permit NC0076775 to the Yadkin Inc. on May 30, 2000. The Division
has reviewed your request for permit modification at the subject facility. Specifically, you requested
removal of the limit for pH.
The basis for the request was that dam seepage through the walls of the powerhouse collected in
the sump drain and that this water possessed elevated pH levels. The high pH in the dam seepage
water cannot be controlled by Yadkin Inc. and causes the effluent to exceed the limit. An attempt to
correct the problem, via steam cleaning the walls, has had no success, therefore Yadkin Inc. requested
that the pH limit be removed.
The general permit for hydroelectric facilities does allow a waiver of the pH limit for dam seepage
water. Therefore, In accordance with your permit modification request, the Division is forwarding
herewith a modification to the subject permit.
The revised page should be inserted into your permit. The old page may then be discarded. All
other terms and conditions contained in the original permit remain unchanged and in full effect. This
permit modification is issued under the requirements of North Carolina General Statutes 143-215.1 and
the Memorandum of Agreement between North Carolina and the U. S. Environmental Protection
Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit
modification 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 a written petition conforming to Chapter 150B of the North Carolina General
Statutes, 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.

RE. VIOLATION OF pH LIMIT - YADKIN FALLS DAM - NPDES PERMIT NO. NC0076775
Gentlemen:
As a follow-up to my phone conversation with Mr. Mike Parker of the Mooresville Regional Office on 2000
October 19, on behalf of Yadkin, Inc, Alcoa is providing the Division of Water Quality with this letter to
report a violation of the pH limit for Outfall 007. The problem was discovered during the initial round of
NPDES monitoring which was being conducted under the recently renewed Yadkin Falls NPDES permit
which became effective 7/1/00. At 9:23 on 10/19/00, a pH measurement of 9.4 pH units was recorded for
Outfall 007. The subsequent investigation has revealed that the source of the problem is attributable to water
seepage from the walls inside the Powerhouse which are leaching lime and calcium from the concrete and
mortar used in the construction of the walls of the building. The wall seepage is collected throughout the
Powerhouse in a system of small floor troughs which carry the low volume of alkaline seepage water to the
basement sump which then discharges the water through Outfall 007. In an effort to attempt to correct the
problem, Yadkin is planning on powerwashing the system of troughs and the sump to attempt to remove as
much of the calcium and lime residue as possible. Once this is completed, we will take additional pH
measurements to verify what effect this has on the situation. At this point, based on this new discovery
during the initial round of monitoring, and the fact that we are not sure how this approach will effect the
long term nature of the problem, we would ask that the agency realize that the nature of the problem may
require further discussion regarding this recently issued permit to assist us in determining what other
alternatives there may be for addressing the situation which currently exists.
Very Truly Yours,
William L. McCaskill

STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Water Quality.
2. DEM or "the Division"
Means the Division of Water Quality, Department of Environment, Health and Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC
1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass. of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this sum by the number of days the tests were
reported. The limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharge's sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as "Weekly Average" in Part 1 of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part I of the permit.

Part II

6. Concentration Measurement
a . The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum" under "Other Limits" in Part 1 of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day . The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under "Other Limits" in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is
considered to be the "daily average concentration" for the discharge. It is identified as "daily
average" in the text of Part I.
f. The "quarterly average concentration" is .the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part 1 of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through March,
April through June, July through September, and October through December.

7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged
monthly. It is determined as the arithmetic mean of the total daily flows recorded during the
calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when
both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs
continually 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.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) 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
(2) 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 present gallon interval between sample collection fixed at
no greater than 1 /24 of the expected total daily flow at the treatment system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time of
greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals
evenly spaced over the 24 hour period which are equal in number of hours to the detention time
of the system in number of days. However, in no case may the time interval between effluent
grab samples be greater than six (6) hours nor the number of samples less than four (4) during a
24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual
values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the
individual values where N is equal to the number of individual values. The geometric mean is
equivalent to the antilog of the arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one
(1).
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows.

Part II
Page 8 of 14
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
permit.
4. Bypassing of Treatment Facilities
a. Definitions
(1) "Bypass" means 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.
(2) "Severe property damage" means substantial physical damage to property, damage to the
treatment facilities which causes them to become inoperable, or substantial and permanent
loss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage does not mean economic loss caused by delays in
production.
b. Bypass not exceeding limitations.
The permittee may allowany bypass to occur which- does not cause effluent limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient operation. These
bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall
submit prior notice, if possible at least ten days before the date of the bypass; including an
evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against
a permittee for bypass, unless:
(A) Bypass was unavoidable to. prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes or maintenance during normal periods of
equipment downtime. This condition is not satisfied if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventive maintenance;
and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.

Part II
Page 9 of 14
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the
reasonable control of the permittee. An upset does not include noncompliance to the extent
caused by operational error, improperly designed treatment facilities, inadequate treatment
facilities, lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this permit.
(4) The permittee complied with any remedial measures required under Part II, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has
the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of
wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such
as to prevent any pollutant from such materials from entering waters of the State or navigable
waters of the United States. The permittee shall comply with all existing federal regulations
governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503, any permit issued
by the Permit Issuing Authority for the utilization/disposal of sludge may be reopened and
modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503. The
permittee shall comply with applicable 40 CFR Part 503 Standards for the Use and Disposal of
Sewage Sludge (when promulgated) within the time provided in the regulation, even if the permit
is not modified to incorporate the requirement. The permittee shall notify the Permit Issuing
Authority of any significant change in its sludge use or disposal practices.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation,
Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability, to prevent the
discharge of untreated or inadequately treated wastes during electrical power failures either by
means of alternate power sources, standby generators or retention of inadequately treated effluent.

and conditions of the Permit. If you have not already done so, it is suggested that you
thoroughly read the Permit. Of particular importance are Pages 4 and 5.
Pages 4 and 5 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth. The section
headed "Monitoring Requirements" describes the measurement frequencies, sample types and
sampling locations. Upon commencement of your discharge (or operation), you must initiate
the required monitoring. The monitoring results must be entered on reporting forms
furnished or approved by this Agency. If you have not received these forms, they should be
arriving shortly. If you fail to receive the forms, please contact this Office as quickly as
possible. I have enclosed a sample of the "Effluent" reporting form (DEM Form MR-1), plus
instructions for completing the form. It is imperative that all applicable parts be completed,
and the original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be
required for your facility. You will soon be receiving a statement from our Raleigh Office. It
is imperative that the fee be paid in a timely manner so as to prevent enforcement action or
possible revocation of your permit.

Subject: Permit No. NC0076775
Falls Powerhouse
Stanly County
Dear Mr. McCaskill:
The Division has reviewed the Yadkin Inc. comments of October 17, 1999 in response to their draft
NPDES permit. The Division has considered the concerns raised and has modified the permit in
accordance with current Division policy, all responses to concerns and revisions made to draft permit,
NC0076775, are explained below:
Comment #1: Clarification of the pH monitoring requirement, since Yadkin Inc. does not add any
chemical additives to the source water.
Response: The hydrogen ion content of water is considered a generic measurement of water quality and
as such is included as a condition of the general permit for hydroelectric facilities. Since the conditions of
the general permit are considered minimum requirements, the semi-annual monitoring of pH, for outfalls
001, 002, 003, 004, and 005 and the quarterly monitoring of outfall 007, will remain as a condition for
this permit.
Comment #2: Clarification of the temperature monitoring requirement. The maximum temperature
change across the generator is 25 °C with a the ratio of cooling water discharge to generator discharge of
1:30,000. Therefore, the worst case temperature rise of the Yadkin River due to cooling water discharge
would be 0.0083 °C, assuming an ambient water temperature of 20 °C.
Response: As with pH, temperature is considered a generic measurement of water quality and as such is
included as a condition of the general permit for hydroelectric facilities. Since the conditions of the
general permit are considered minimum requirements, the semi-annual monitoring of temperature will
remain as a condition for this permit.
Comment #3: Yadkin Inc. request that Discharge Monitoring Reports (DMR) submittal be waived.
Response: Since Yadkin, Inc. request coverage under an individual NPDES permit, DMR reporting is
required.

Comment #4: Since it is impractical to obtain samples at the point of discharge, Yadkin Inc. request
approval for sampling at the closest point to discharge where a representative sample can practically be
obtained.
ReSpoi se,"...T13e Division agrees that this is a reasonable request and has included the phrase, "E —
".Effluent or the point closest to discharge where a representative sample of the discharge can feasibly be
r#" 'obtained." to allow for sampling at the sump upstream of the discharge.
Comment #5: The cover letter states that the pH limitation will include the phrase "unless ambient river
conditions prevent compliance with this range", however this phrase does not appear in the pH footnote.
Response:' The phrase "unless ambient river conditions prevent compliance with this range" has been
inserted into Note 2 on the Effluent Limitations and Monitoring Requirement page.
Comment #6: The fact sheet notes that the "facility is not required to perform any instream monitoring".
If the boiler plate language relating to increases in stream temperature cannot be removed from the
Effluent Limitations and Monitoring, Requirements page, then this same statement needs to be reflected
on the Effluent Limitations and Monitoring page as a footnote.
Response: The temperature footnote contained in the permit is reflective of the water quality standard for
temperature as contained in the 02B .0200 rules. Therefore, a discharge cannot raise the temperature of
the receiving stream by more than 2.8 °C or cause the receiving stream to exceed 32°C (for lower
piedmont and coastal plain waters) even if temperature is not specifically addressed in the conditions of
the permit. Though the temperature footnote will remain in the permit, the intent of this limitation is not
to require instream monitoring of temperature for reporting purposes.
Comment #7: Clarification of BMPs related to the changing of oil absorbent pads on a quarterly basis.
Yadkin Inc. does not utilitize oil absorbent pads for the sumps. Instead Yadkin Inc. uses a rope skimmer
type oil water separator.
Response: Since oil absorbent pads are not utilized at this facility the BMP language has been altered to
better reflect the current operations at this facility. BMPs for the rope skimmer type oil/water separator
will remain as a condition of the permit.
Comment #8 and #9: Yadkin Inc. request that note #1 on the A(2) Effluent Limitations and Monitoring
Requirement page be changed to "The tailrace shall be visually inspected for oil sheen attributed to
facility operations on a weekly basis in conjunction with inspections of the floor sump and rope
skimmer." Additionally, Yadkin Inc. request that note #1 on the A(2) Effluent Limitations and
Monitoring Requirement page be replaced with language that requires the tailrace inspections to be
logged in the operating log instead of on the DMRs.
Response: The Division recognizes Yadkin Inc.'s concern with the liability of the language contained in
the draft permit and has no objection to the proposed language, however in order to assure the availability
of data, the footnote has been modified as follows:
"The tailrace shall be visually inspected for oil sheen attributed to facility operations on a weekly basis in
conjunction with inspections of the floor sump and rope skimmer. Confirmation that a visual inspection
was conducted shall be recorded in the operating log for the facility and provided to the Division upon
request."

Comment #10: Yadkin request that the `Boiler Plate" language related to the discharge of floating solids
or visible foam be removed from the Effluent Limitations and Monitoring Requirements page. Foam is
not uncommon on the downstream side of the hydroelectric plant, however this foam is due to turbulence
and surfactants or other foam causing agents present in the ambient river water.
Response: The Division agrees that Yadkin Inc. cannot control the characteristics of the influent ambient
river water, therefore the phrase "unless ambient river conditions prevent compliance" has been added to
the language.
Comment #11: Effluent Limitations and Monitoring Requirements page for outfalls 001, 002, 003, 004,
and 005: The monitoring frequency for these outfalls is semi-annual, however the reporting frequency is
quarterly. Yadkin Inc. request that the reporting frequency mirror the monitoring frequency for these
outfalls.
Response: The quarterly monitoring frequencies for these outfalls were placed in the draft permit in
order to maintain consistency throughout the permit. This was done as a matter of convenience to the
Division and the permittee. However, the Division recognizes the permittee's concerns over the liability
of this requirement and has changed the reporting requirement to mirror the monitoring frequencies.
Attached is the NPDES permit No. NCD076775 issued December 23, 1999. 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 US Environmental Protection Agency dated December 6,
1983.
Please take notice that this permit is not transferable. Part II, E.4. addresses the requirements to be
followed in case of change in ownership or control of this discharge. This permit does not affect the legal
requirement to obtain other permits which may be required by the Division of Water Quality or permits
required by the Division of Land Resources, Coastal Area Management Act or any other Federal or Local
government permit that may be required.
If any parts , measurement frequencies or sampling requirements contained in this permit modification 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 a written petition conforming to chapter 150B
of the North Carolina General Statutes, filed with the Office of Administrative Hearings, Post Office
Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is made, this decision shall be
final and binding.
If you have any questions concerning this permit, please contact Mr. Michael Myers at telephone number

4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC
1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily -discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this, sum by the number of days the tests were
reported. The limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average, annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar daythe concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day . The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under "Other Limits" in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the. sample is
considered to be the "daily average concentration" for the discharge. It is identified as "daily
average" in the text of Part I.
f. The "quarterly average concentration" is • the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
A calendar quarter is defined as one of the following distinct periods: January through March,
April through June, July through September, and October through December.

monthly. It is determined as the arithmetic mean of the total daily flows recorded during the
calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when
both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement is a measure of discharge flow from the facility which occurs
continually 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.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) 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
(2) 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 present gallon interval between sample collection fixed at
no greater than 1/24 of the expected total daily flow at the treatment system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time of
greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals
evenly spaced over the 24 hour period which are equal in number of hours to the detention time
of the system in number of days. However, in no case may the time interval between effluent
grab samples be greater than six (6) hours nor the number of samples less than four (4) during a
24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual
values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the
individual values where N is equal to the number of individual values. The geometric mean is
equivalent to the antilog of the arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one
(1).
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows.

caused by operational error, improperly designed treatment facilities, inadequate treatment
facilities, lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.

Dear Mr. Polk:
Please find enclosed the draft permit for the Falls Hydroelectric Powerhouse facility for your review and comment.
The draft permit includes the following items:
• Temperature monitoring and limits have been implemented and the words "due to facility operation" have been
included in the footnote.
• Limits and monitoring requirements have been set for oil and grease. The footnote requires the tailrace be
visually inspected at least once per quarter or when, lubrication occurs and that best management practices be
employed.
The pH limitation includes the words "unless ambient river conditions prevent compliance with this range."
• Language concerning quarterly DMR submission is specified on the effluent pages. For any outfalls requiring
only semi-annual monitoring, the language is the same to maintain reporting frequencies consistently
throughout the permit.
• Total residual chlorine monitoring has been eliminated, since chlorine is not utilized at this facility.
• The footnote prohibiting the addition of chromium, copper, or zinc to the discharge has been removed, as this
condition has been adequately addressed in the requirement to notify the Division of any additives possibly
toxic to aquatic life.
• BMPs include the changing of the oil absorbent pads quarterly and routine cleaning of the sediment in the
bottom of the sump.
• Chemical wheel pit cleaning is permitted on a monthly basis with pre -approved solvents.

The Division has considered your request for BMPs for all permitted outfalls. Though it is the Division
policy to encourage the use of BMPs we can not at this time grant your request. As I am sure you are
aware your facility is eligible for coverage under general permit NCG500000, however, Yadkin Inc. has
requested an individual permit. For those hydroelectric facilities requesting individual permits in lieu of
coverage under general permit NCG500000, it is the Division's intent to permit these facilities
consistently. Therefore, the Division has used the permit requirements contained in the general permit as
a guide in issuing all individual permits for hydroelectric facilities statewide.
The "boilerplate" language is considered standard conditions and cannot be changed to represent
individual facilities. The requirement to include standard permit conditions verbatim or by reference is
stipulated in 40 CFR 122.43. Language is interpreted appropriately for each facility.
Please provide any comments you have regarding this draft permit to DENR — DWQ NPDES Unit no
later than October 22, 1999. Concurrent with this notification, the Division is also publishing a notice in
the newspapers having general circulation in the Stanly county area, soliciting public comment on the
draft permit. Following the 30-day public comment period, the Division will review all pertinent
comments and take appropriate action prior to issuance of the final permit.
If you have any questions concerning the draft permit for your facility, please call me at [phone],

SUMMARY
This facility maintains 6 outfalls (001, 002, 003, 004, 005 and 007) With the exception of outfall 007 (sump
drain) the source of water for the other outfalls is once through cooling water. The old permit stipulates that
outfalls 001 through 005 monitor (with no limits) flow, temperature and total residual chlorine with no
discharge monitoring report is required because of the use of BMP's.
Yadkin Inc. has requested that monitoring be replace by implementation of BMP's. Additionally Yadkin, Inc
requested that the pH and temperature "Boiler Plate" language be excluded from the permit. This plant is
eligible for coverage under general permit NCG50000, however, they choose to use the individual permit
because the general permit does not provide a provision for BMP practices in lieu of monitoring. In the next
renewal of the general permit the viability of providing such a provision into the permit should be examined.
DWQ's goal for those hydroelectric facilities that request an individual permit instead of an asking for
coverage under the general permit is consistency. Therefore, permit NC0027332 and general permit
NCG500000 were used in developing this draft permit for the hydroelectric plants owned by Yadkin, Inc. in
the Yadkin River basin.
The receiving stream (Yadkin River) is classified as WS-IV and B CA waters from Badin Dam to a point 0.5
miles upstream of Falls Dam. This reach is not listed on the 303(d) list as impaired water. According to the
May 1998 Yadkin -Pee Dee River Basinwide Water Quality management Plan this reach has been classed as
supporting its designated uses.
TOXICITY TESTING:
Current Requirement: N/A
Recommended Requirement: N/A
COMPLIANCE SUMMARY:
To date this facility has not been required to submit Discharge Monitoring Reports (DMR) because of the
implementation of Best Management Practices. However a historical review of inspection reports was
Yadkin.Inc. — Falls Hydroelectric Powerhouse Fact Sheet
NPDES Renewal
Page 1

conducted and Mike Parker (Mooresville Regional Office) was contacted regarding compliance issues. With
the available information it was concluded that this facility has no compliance issues.
INSTREAM MONITORING:
This facility is not required to perform any instream monitoring.
PROPOSED CHANGES:
Outfall 007 - Permit limits will be applied to the sump drain outfall 007 for oil and grease. Additionally,
monitoring will be required for flow, oil and grease, and pH, with quarterly reporting requirements, as
outlined on the Effluent Limitations page.
Outfalls 001, 002, 003, 004, and 005 — Monitoring and/or limits have been set for flow and temperature as
outlined on the Effluents Limitations page.
DMR submittal - DMRs will need to be submitted quarterly for all outfalls.
Total .Residual Chloride (TRC) - Total residual chlorine monitoring will be removed from the permit, since
chlorine is not utilities at this facility.
Chromium, zinc, and cooper restriction - The chromium, zinc, and copper excerpt will be excluded since this is
adequately addressed in the notification requirement if any toxicants are to be added.
Temperature - Temperature requirement will reflect the situation if natural conditions raise the ambient temp
above 32°C.
Tailrace clause — The tailrace clause requiring inspection has been reworded to ensure inspection at least
quarterly and after lubrication activities at the facility.
Chemical and Mechanical Sump Cleaning Clauses — Though this may not be applicable to this facility it has
been included to ensure that this facility is consistent with other hydroelectric facilities across the state.

These permit renewals will be handled by Bethany Bolt of the NPDES Unit. I'm sad to inform you that we have
lost several staff members in the past few months - the NPDES Unit now has five vacant positions.
This staff shortage is causing delays in our processing of permit renewals. Our remaining staff are currently
reviewing Authorizations to Construct, speculative limit requests, major permit modifications and 201 plan reviews
ahead of permit renewals. This is necessary due to a variety of factors, including mandatory deadlines in the
statutes which govern our program.
If this staff shortage delays reissuance of the four permits listed above, the existing requirements in the permits
will remain in effect until the permits are renewed (or other action is taken by the Division). We appreciate your

Subject: Renewal of NPDES Permit NC0076775
Falls Powerhouse
Stanly County
Dear Permittee:
The subject permit expires on August 31, 1999. North Carolina General Stature 143.215.1(c) requires that an
application for permit renewal be filed at least 180 clays prior to the expiration date.
To satisfy this requirement, your renewal package must be sent to the Division postmarked no later than March 4,
1999. Failure to request renewal by March 4, 1999 will result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending upon the delinquency of the request.
If any wastewater discharge will occur after August 31, 1999 (or if continuation of the permit is desired), the permit
must not be allowed to expire. Operation of waste treatment works or continuation of a discharge after August 31,
1999 would violate NCGS 143-215.1 and could result in assessment of civil penalties of up to $10,000 per day.
If all wastewater discharge has ceased at the subject facility and you wish to rescind this permit, contact Robert
Farmer of the Division's Compliance Enforcement Unit at [phone], extension 531. You may also contact the
Mooresville Regional Office at [phone] to begin the rescission process.
Use the enclosed checklist to complete your renewal package. The checklist identifies the items which you must
submit when applying for renewal of the subject permit.
If you have any questions, please contact me. My telephone number, fax number and e-mail address are listed below.

STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DaINITIONS
1. Permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or Division
Means the Division of Environmental Management, Department of Environment, Health and
Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended. 33
CSC 1251, et. seq.
5. MassfDav Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and'or measured during, a calendar month on which daily discharges are sampled
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days
the tests were reported. The limitation is identified as "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during, the calendar week (Sunday - Saturday) on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled and/or
measured during such week. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in
Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of
the daily concentration values). The daily concentration value is equal to the concentration
of a composite sample or in the case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The average weekly count
for fecal coliform bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as
"Daily Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily
discharges sampled and/or measured during such year (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day . The average yearly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar year. This limitation is identified as "Annual Average" under "Other Limits" in
Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount
of dissolved oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the
sample is considered to be the "daily average concentration" for the discharge. It is
identified as "daily average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
A calendar quarter is defined as one of the following distinct periods: January through
March, April through June. July through September, and October through December.

7. Other\Ieasurements
a. Flow. (MGD): The flow limit expressed in this permit is the 24 hours average flow,
averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded
during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling,
when both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which
occurs continually 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.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(11 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
(2) 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 present gallon interval between sample
collection fixed at no greater than 1/24 of the expected total daily flow at the treatment
system. or
(3) a single. continuous sample collected over a 24 hour period proportional to the rate of
flov.w.
In accordance with (1) above. the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time
of greater than 24 hours. In such cases, effluent grab samples may be collected at time
intervals evenly spaced over the 24 hour period which are equal in number of hours to the
detention time of the system in number of days. However, in no case may the time interval
between effluent grab samples be greater than six (6) hours nor the number of samples less
than four (4) during a 24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the
individual values divided by the number of individual values.
b Geometric Mean: The geometric mean of any set of values is the Nth root of the product of
the individual values where N is equal to the number of individual values. The geometric
mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual
values. For purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).

Part II
Page 4 of 14
c. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10. Calendar Dav
A calendar day is defined as 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.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to
Section 311 of the Clean Water Act.

inadequate treatment facilities, lack of preventive maintenance, or careless or improper
operation.
b. Effect of an upset.
.An upset constitutes an affirmative defense to an action brought for noncompliance with
such technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Falls Powerhouse discharges below Falls dam and below the dam at Badin Lake. Per DWR
(5/92), no minimum release exists in their 1958 FERC license, although a release of at least 150
cfs from Blewett Falls (many miles downstream) is to be maintained. Previous WLA's for these
discharges stated that Yadkin Inc. was required to maintain a minimum release of 1400 cfs from
Badin Lake (This may be self-imposed and will be used by TSB).
This WLA was previously permitted under NC0076775-001. ALCOA is consolidating several
outfalls under one permit.
The facility had been meeting its limits until 2/92. It has problems with underloading; ALCOA is
considering going to a subsurface disposal system.
Due to "B" waters classification, Fecal coliform limits must be applied.

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Yadkin, Inc. (a subsidiary of ALCOA), operates
a powerhouse (dam) on the Yadkin River known as Falls Powerhouse,
which generates hydroelectric power used in ALCOA's aluminum
manufacturing process. Complex electrical generation machinery
exists at this facility, that requires cooling water during
operation. There is one discharge of treated domestic wastewater
from Powerhouse maintenance employees.
Presently, the cooling water and domestic wastewater
discharges from this facility are covered under two (2) separate
NPDES Permits-(NC0004308 issued to ALCOA, and NC0076775 issued to
Yadkin, Inc.). Yadkin, Inc. request that these discharges be
included in one Permit to reduce paperwork and simplify tracking.
This Office, therefore, recommends that outfalls 001, 002, 003,
004, 005 and 007 be included in NPDES Permit No. NC0076775, which
already exist for outfall 006 (domestic wastewater discharge), and
that Permit No. NC0081922 (a new Permit Number) be deleted. As a
result of this change, ALCOA's Permit (NC0004308) will require a
modification to delete the outfalls associated with the Powerhouse.
It is suggested that a modification to Permit No. NC0004308 be made
in conjunction with the processing of this application. A request
for the modification can be found in the transmittal letter from
Yadkin, Inc. which accompanied this application.

Page Four
Yadkin, Inc. also requested in their transmittal letter that
monitoring not be included in the Permit for the cooling water
discharges, rather the company will use Best Management Practices
(BMP's) to remove pollutants. These BMP's include, but are not
limited to, changing of oil absorbent pads (quarterly) and the
cleaning of sediment in the bottom of oil sumps (annually). A
record of this routine maintenance would then be provided to the
Division on a quarterly basis. Recent Permits issued by the
Division for non -contact cooling water do not include effluent
monitoring. Although the possibility exist that lubrication fluids
may enter the receiving stream, the concentrations and subsequent
.effects are expected to be minimal and downstream impacts are not
expected. We, therefore, concur with Yadkin, Inc.'s request and
recommend approval pending concurrence by Technical Support.
Yadkin, Inc. has been experiencing problems with the
chromaglas unit which serves this facility due to severe hydraulic
underloading. Maintaining a sufficient solids inventory has been
difficult, which has resulted Permit violations. Yadkin is
considering abandonment of the existing facility and the
construction of a subsurface disposal system on property located
nearby.
Pending receipt and approval of the WLA and concurrence by
Technical Support of Yadkin, Inc.'s request, it is recommended that
Permit No. NC0076775 be modified to included the additional
outfalls.

Enclosed are permit applications for the four Yadkin, Inc. hydrogeneration plants,
along with the biocide certificates and processing fees. The discharges are
predominantly composed on non -contact cooling water; however, some domestic
wastewater flows are included (see individual applications and site maps for further
information). Special note should be made of the existing permitted outfalls at the
Falls, Narrows, and Tuckertown facilities and the drawing of the proposed
wastewater treatment system for the domestic sewer flow at the Narrows plant.
It is our desire to obtain one NPDES permit for each facility. We believe that this
will benefit both Yadkin and the State in the elimination of duplicate permitting of
outfalls and reduction in both paperwork and record keeping.
In addition, we request consideration of a best management practice (BMP)
provision for all but the two treated domestic sewage outfalls. This will allow us
to perform routine monitoring of the non -contact cooling water discharges or
employ BMP to ensure that excessive pollutants are not discharged. Past permits
issued for TVA's hydroelectric generation plants contain such a provision which
states, "In lieu of these monitoring requirements, BMPs may be employed to ensure
that excessive pollutants are not discharged to the surface waters of the state.
These practices should include, but are not limited to, changing oil absorbent pads
quarterly and cleaning accumulated sediment in the bottom of sumps at least
annually." This option would ensure safe discharge while reducing operating costs
by eliminating analytical testing and its associated paperwork. Should this request
be granted, and the option exercised, we would provide quarterly written
certification of BMP activities to the state.

SUBJECT: Request for Authorization to Construct
AC 0076775 - Wastewater Treatment Facilities
Falls Power Plant
NPDES Permit No. NC 0076775
Stanly County, North Carolina
This Office has reviewed the subject request and recommends
it be approved. Please be advised, the proposed facility is a
Cromaglass CA-5 wastewater treatment unit which has a design
capacity of 500 gpd. The treatment unit is to. be installed.
inside an existing, but inoperative, restroom in the power
plant. The projected domestic wasteflow of 50.0 gpd is to be
discharged into a segment of the Yadkin River. between Badin Lake.

Pursuant to our conversation concerning the installation
of a Cromaglass CA-5 wastewater treatment unit at your service
facility near Badin, I understand that:
1. The site is at a remote service facility frequented
occasionally by service personnel and has a commode,
washbasin and shower, and no non -domestic wastewater.
a. Normal usage : 1 person x 2 hr/day x 25gpcd = 50 gpd
1 shower = 20 gpd
b. Worst case usage:
5 persons/day x 25 gpcd
1 shower x 2
70 gpd
= 125 gpd
= 40 gad
185 gpd
2. A Cromaglass CA-5 unit (nominal 500 gpd) is adequate
to handle this service requirement.
3. A building sewer exists into which the CA-5 can be
inserted.
4. You will obtain the required discharge permit and inter-
face with the regulator agency. We will provide infor-
mation and general assistance in this regard.

Enclosed are several drawings related to the installation of
the CA-5 unit. These are:
1. General brochure on Cromaglass controlled batch
wastewater treatment equipment showing sizes, general
operation data and power requirements.
2. CA-5 detailed drawing (Dwg #CA-5)
3. CA-5 operating instructions
4. 50-gal. chlorinator (Dwg. #CC-50)
5. Site installation drawing
I have shown the 50-gallon chlorinator in case you will be
required to disinfect. It uses the normal pill -type chlorine
tablets used in swimming pools. If a restriction of suspended
solids is a requirement, then a cannister type swimming pool
filter can be utilized on the discharge pipe prior to chlori-
nation.
Pricing of the equipment is as follows:
CA-5 unit
50 gallon chlorinator
$3,344.73
$420.98
The above costs do not include sales taxes or shipping
charges. Normally, we require a 50% deposit at the time an
order is placed, with the balance due upon delivery.

SEWAGE TREATMENT SYSTEM
Cromaglass Systems have been designed to operate most efficiently if installed, operated, and
serviced by a contractor experienced in the field of sewage disposal systems. Installation must be
made in strict accordance with regulations of local. state, or federal standards. Contractor must have
applied for and been issued a permit for operation of the system.

Note that there are four specific steps of treatment. When chlorination is not required,
Step 4 is omitted.
Operating instructions for the system will be covered in the following paragraphs, but the
installation should be complete per instructions sent with the tank and pumps. There are some.
simple checks to be made prior to beginning operation of the system:
1. Is adequate power supplied to the control box?
2. Are all wires routed properly and connections made?
3. Have the pumps been run momentarily to assure proper operation?
4. Are all piping connections made, and tight?
5. Has all debris, etc., been removed from tanks?
(Pumps can be plugged or damaged by foreign articles).
STARTING AND OPERATING SYSTEM
Before the plant is put into actual operation, it is necessary to understand the process and
sequence of events that will take place. Within the Sales section of your Cromaglass Catalogue,
there are pages entitled Features and Process Description. (This description is also found on
Page 4 of the Cromaglass Brochure). These Process Descriptions should be reviewed prior to and
while operating the system. (Note flow diagram of process).
-2-

At time of installation, the tank should have been filled with water to approximately y of it's total
depth, so make certain this has been done prior to initiating operation of the pumps. Note that 1st
compartment of the tank is a comminution or solid break up compartment. All incoming sewage
enters this compartment and is broken up into fine particles by a strong force of combined water
and air directed at the plastic screen from a nozzle located in .the aeration compartment.
Comminution is created through a non -mechanical means that cannot jam and create time
consuming efforts. Should the screen become clogged from extensive amounts of plastic orsimilar
articles, a high water alarm float bulb located at the top of the chamber will signal via flashing red
light or audible alarm and it will be necessary by using a rake type tool to remove these articles or
substances from the plastic screen or in flotation and dispose of them as required. Periodic removal
of these materials should be made from the comminution chamber in any event.
CONTROL PANEL
A control panel is the "heart" of the Cromaglass Batch Treatment System and it houses the
following items:
1. Time Clock with two micro switches controls Pump P-1 and P-2.
.2. Amber color running lights for pumps.
3. All necessary relays and control devices for the proper operation of system.
4. High water alarm which activates buzzer.
Sequence of control is such that time clock is factory set to operate at 4 hour cycles- through 3
hours on and 1 hour off. A preset maximum of treated effluent is discharged on each timed cycle but
may be Tess than the maximum depending upon incoming flow to the total system. The batch
treatment system processes 16 hours of inflow in 24 hours. This means that 480 GPD System will
accept this quantity in 16 hours. If this flow takes over 16 hours, the plant will go on standby and
process only that quantity, but if more than the 480 GPD flow occurs, the system has enough
reserve volume to process the extra amount without affecting the plant system's efficiency.
It is important to realize that relays within the control panel automatically activate the discharge
pump electrical system at the end of each cycle's 1 hour settling period. It is not possible for the
discharge pump to be initiated unless there has been one hour of settling in its chamber.
AERATION TANK
Pump P-1 creates an optimum amount of aeration within the main aeration chamber. Although
these pumps are heavy duty water pumps, they should be checked periodically to assure that they
have not become clogged from stringy articles such as hair or long particles from textiles. Should
the P-1 Pump fail you would not be aerating or transpiring to the Clarifier.
Should the alarm system be activated and there is no noticeable excess of clogging materials in
the comminution chamber, there is a possibility that P-2 Pump is malfunctioning. (This would cause
water level in the entire main chamber and comminution chamber to rise and signal through the
float level device.)
-3-

AIR FLOW
It is important that a programmed quantity of air flows to the entire system. A check should be
made occasionally for proper aeration by first visually estimating proper amount of turbulence
within the main aeration chamber. Also, aeration can be determined by placing a hand against the
air intake where ever it may be located. Adequate suction would indicate proper amount of
aeration.
OVERLOAD
There may be an occasion when an extraordinary overload of incoming wastewater cannot be
adequately handled through the programmed cycle. In such a situation, it may be necessary for the
operator to temporarily speed up the process by limiting the aeration cycle of P-1 Pump to 2 hours
instead of the standard 3. This is accomplished by changing the settings on the time clock so that a
maximum of 2 hours aeration will take place. This should not affect the total aeration capabilities or
effluent quality. Note that if heavy surges have caused a frequent changing of the 3 hour aeration
period, there is undoubtedly an indication of an overload on the system as originally sized and
provisions should be made for increasing the total capacity.
Should the operator be unable to correct conditions beyond which these instructions can help
him, a phone call should be made to the nearest Cromaglass District Representative or the closest
Cromaglass factory.
