Harris Nuclear Plant
Wake County
Dear Mr. Robinson:
In accordance with the application for a discharge permit received on October 4, 1995
the Division is forwarding herewith the subject NPDES permit. This permit is issued pursuant
to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated
December 6, 1983.
4` The following comments are provided in response to the May 24, .1996 comments
submitted by CP&L regarding the draft permit. Although the CP&L comments were not
sequentially numbered, the following responses are in corresponding order to,the comments
received.
General Comments
The final permit pages have been sequentially numbered as requested.
The Fact Sheet and Waste load Allocation were provided to Jeannie Cook during our May 13,
1996 meeting concerning the draft permit comments.
Page 2
The next to last paragraph has been changed to "Any other wastewater, and stormwater
associated wiih�industrial activities point source discharge to surface waters of the state is
prohibited unless covered by another permit, authorization or approval." as requested.
Page 4
- General Statute 143-212. defines "waters" as 'any... waterway or other body or accumulation
of water, whether... public or private, or natural or artificial, that is contained in, flows
`1 through, or borders upon any portion of the State...' Under this definition., the channels in
question are considered waters of the state and are thereby subject to stormwater regulation.

With regard to toxicity testing, CP&L is correct in their statement that the intent of retesting is
to require that the retesting be performed within 30 days if a test condition fails. However, a
retest should also be conducted if te4 results indicate an invalid test. An invalid test will not
be deemed as noncompliant. Any ftiilure of a toxicity test is deemed noncompliant. Any
questions regarding these requirements can be discussed with Mr. Matt Matthews of my staff

Although the mixing zone is applicable at the final discharge (outfall 006), requirements for
the mixing zone are pertinent to the cooling tower component of the final discharge.
Therefore, the mixing zone language is presented on the outfall 001 effluent limitation page
for clarity regarding the intent of the mixing zone.
Zinc and Chromium have been listed as Total Zinc and Total Chromium.
Based upon a review of discharge monitoring report data, the monitoring requirements for
Total Nitrogen and Total Phosphorus have been deleted for outfall 001. Because outfall 006
is the final combined outfall with discharge to a lake, and all lakes are subject to nutrient
concerns, monitoring for these two parameters shall be required at the final outfall:
The footnote "Test procedures shall produce minimum detection or lower reporting level of
the approved procedure." has been inserted as requested.
Page 9
The pH monitoring and the "no floating solids or visible foam..." footnote have been deleted
as requested.
In footnote (+) "Total residual chlorine" has been deleted from the first sentence,
"instantaneous average" has been replaced with "daily average", and "instantaneous
maximum" has been replaced with "daily maximum" as requested.
The second sentence of footnote (++) has been replaced with the suggested language, "There
shall be no discharge of detectable amounts of the 126 priority pollutants contained in
chemicals added for cooling tower maintenance except for Total Chromium and Total Zinc.'
Page 10
The Division routinely applies monthly average and daily maximum effluent limitations based
upon the distinction between "municipal" and "non -municipal" in the Clean Water Act. Under
40 CFR 133, secondary treatment requires the removal of 85% of the influent BOD5 and
TSS. The adoption of daily maximum limitations allows the Division to meet the requirement
of being at least as stringent as the federal regulations without having to require 85% removal.
In order to provide weekly average limitations in this permit, the permit would also have to
require influent monitoring for BOD5 and TSS and 85% removal of influent BOD5 and TSS.
The permit is being issued with daily maximum limitations. However, should CP&L wish to
pursue weekly average limitations with 85% removal requirements a permit modification may
be requested.
The pH monitoring and the "no floating solids or visible foam..." footnote have been deleted
as requested.
NCAC T15A: 02B .0508 specifies Fecal Coliform and Total Residual Chlorine monitoring of
domestic wastewater discharges at the frequencies provided. in the draft permit. However,
~6 -� based upon a review of discharge monitoring data for outfall 002, the monitoring frequencies
for Fecal Coliform and Total Residual Chlorine have been reduced to weekly.

The footnote "Test procedures shal�produce minimum detection or lower reporting level of
the approved procedure." has been i serted as requested.
NCAC T15A: 02B .0508 requires ammonia monitoring of domestic wastewater discharges at
the frequencies provided in the draft permit. Based upon a review of discharge monitoring
data for outfall 002, the monitoring frequency for NH3 as N has been reduced to monthly.
Nitrogen and phosphorus monitoring requirements have been deleted at all internal outfalls.
Because outfall 006 is the final combined outfall with discharge to a lake, and all lakes are
subject to nutrient concerns, monitonng for these two parameters shall be required at the final
outfall.
Page 11
Oil and grease and TSS monitoring are required for metal cleaning wastes per 40 CFR
423.12(b)(5). Because any discharge from outfall 003 is routed through outfall 004, which
contains equivalent limitations foroil and grease and TSS, the oil and grease and TSS
monitoring at outfall 003 have been deleted.

Nitrogen and phosphorus monitoring requirements have been deleted at all internal outfalls.
Because outfall 006 is the final combined outfall with discharge to a lake, and all lakes are
subject to nutrient concerns, monitoring for these two parameters shall be required at the final
outfall.
TSS monitoring at the intake has been deleted.
Pages 15/16
As previously noted, all lakes are subject to nutrient concerns. The discharge at outfall 007 is
to an arm of the lake which escalates the concerns over localized eutrophication. Therefore,
monitoring for total nitrogen and total phosphorus shall be required.
This comment was previously addressed for Page 10.
The acute toxicity sample type for outfall 007 has been changed to composite.
Title 15A of the North Carolina Administrative Code (T15A NCAA 2B .0508 specifies
weekly Fecal Coliform monitoring for Class II treatment facilities which discharge primarily
domestic wastewater. Therefore, weekly Fecal Coliform monitoring is specified for both the
summer and winter effluent pages.
The BODS and Ammonia limitations provided in the permit are not strictly based on
maintaining compliance with DO. The BODS and NH3 as N limitations were agreed upon
between CP&L and the Division as best professional judgement limitations -with Ammonia
also protecting against instream toxicity. If CP&L's concern is that a violation of the
Ammonia limit will automatically cause a violation in the BODS limit, then the Division may
consider a CBOD5 limit in lieu of BODS. Note that the CBOD5 limit will be lower than the
current BODS limit should CP&L request such a modification.
The temperature monitoring requirement is specified in T15A NCAC 02B .0500 for primarily
domestic wastewater discharges.
The language "Test procedures shall produce minimum detection or lower reporting level of
the approved procedure." has been added to both effluent monitoring pages for outfall 007 as
requested

The Division understands the concern over duplicative language. The language in question is
currently part of a standard boilerplate and will be evaluated based upon this comment at such
time as the boilerplate language is revised.

The intent of the language in item A.i.b.(1) is to be reasonable and encourage the application
of best management practices in areas) where they will be reasonably beneficial. The Division
expects the permittee to use sound judgement when determining what is practicable on-site
and does not condone the development of exhaustive engineering studies where they are not
reasonably warranted. Should CP&L identify a specific area of concern, please feel free to
contact the Division for guidance.
The provisions for secondary contain{nent are likewise meant to be reasonably applied using
sound judgement. In response to the comment on item A.l.b.(2) and the language contained
in the CP&L Mayo permit, the definition of bulk storage in Part III, Section A.3. has been
changed to exclude water.

For permitting purposes, the definitio of a discharge is a point source discharge.
The stormwater outfall certification ay be signed by either a responsible corporate officer or

The intent of the vehicle maintenance wording in item A:1.i. is to indicate that although the
primary industrial activity (steam electric generation) may trigger coverage under the
stormwater regulations there are adds tional activities, such as vehicle maintenance, that are
also subject to coverage.
The intent of the word "immediately" in item A.1, i. is that no delay in enacting retrieval of the
information should occur when docu entation is requested. As in the CP&L Mayo permit,
the wording has not been changed.
The reference has been changed to �.�a).

J The first line of item A.2.f. has been changed to read "stormwater discharges associated with
industrial activity" as requested.
Unless specifically noted otherwise, all non-stormwater discharges identified during the
application process are permitted. The discharge of wastewater from the battery room, which
was identified during the draft comment period, is not considered to be permitted and should
be removed.
The Division recognizes that CP&L interprets "contaminated" to mean radioactive. The intent
of "uncontaminated" in item A.21(2) is that there are no chemical additions to the types of
non-stormwater discharges listed.
Item A.21(3) has been changed to read "Discharges resulting from fire -fighting and
uncontaminated discharges resulting from fire -fighting training and associated fire system
testing." Uncontaminated is interpreted to mean those discharges to which no chemical
additions have been made.
Page 22
Representative outfall status is not applicable to visual monitoring. The intent of visually
monitoring each outfall is to identify stormwater pollution problems that would otherwise go
unnoticed.
Spring and fall are defined, respectively, as the period from April - June and September -
- November.
Page 24
The intent of the Section A.3. bulk storage definition is large volumes stored in bulk that have
a capacity of either 660 gallons or adjacent storage tanks with a combined capacity of 1,320
gallons. It is not intended for sources of less than 660 gallons which are scattered'across the
site and have a total combined volume of 1,320 gallons to be considered bulk storage.
Page 28
The 25 year - 24 hour storm event freeboard requirement in Part III.A.19. is based upon the
definition of a non -discharging stormwater control system as discharging only in response to
a storm event exceeding a 25 year - 24 hour storm.
Page 40
The Division recognizes CP&L's concerns regarding item Part III E.9. and will take this
comment into consideration when re -negotiating the Memorandum of Agreement with EPA.
If any parts, measurement frequencies or sampling requirements contained in this
permit are unacceptable to you, you have the right to an adjudicatory hearing upon written

WASTEWATER MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: FINAL LIMITATIONS AND CONTROLS FOR WASTEWATER DISCHARGES
This permit shall be modified, or revoked and reissued to incorporate toxicity limitations and
monitoring requirements in the event toxicity testing or other studies conducted on the effluent or
receiving stream indicate that detrimental effects may be expected in the receiving stream as a result
of this discharge.
✓ 1. Biocide Condition
The permittee shall not use any biocides except those approved in conjunction with the permit
application. The permittee shall notify the Director in writing not later than ninety (90) days prior
to instituting use of any additional biocide used in the cooling systems which may be toxic to
aquatic life other than those previously reported to the Division of Environmental Management.
Such notification shall include completion of Biocide Worksheet Form 101 and a map locating the
discharge point and receiving stream.
.Acute Toxicity Monitoring (Quarterly) - Outfall 006
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined as
definitive in E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to
Freshwater and Marine Organisms." The monitoring shall be performed as a Fathead Minnow
(Pimephales promelas) 48 hour static test, using effluent collected as a 24 hour composite.
Effluent samples for self-monitoring purposes must be obtained during representative effluent
discharge below all waste treatment. The first test will be performed after thirty days from the
effective date of this permit during the months of August, November, February, and May.
The parameter code for this test is TAA6C. All toxicity testing results required as part of this
permit condition will be entered on the Effluent Discharge Form (MR -1) for the month in which it
was performed, using the appropriate parameter code. Additionally, DEM Form AT -l. (original) is
to be sent to the following address:
Attention: Environmental Sciences Branch

J3. Acute Toxicity Pass/Fail Permit Limit (Quarterly) - Outfall 007
The permittee shall conduct acute txicity tests on a quarterly basis using protocols defined in the
North Carolina Procedure Document entitled "Pass/Fail_.Method ology, For Determining Acute
Toxicity In A Single Effluent Concentration." The monitoring shall be performed as a Fathead
Minnow (Pimephales promelas 24 hour static test, using effluent collected as a 24 hour
composite. The effluent concentration at which there may be at no time significant acute mortality
is 90% (defined as treatment two in the North Carolina procedure document). Effluent samples for
self-monitoring purposes must be o tained during representative effluent discharge below all waste
treatment. The first test will be pe ormed after thirty days from the effective date of this permit
during the months of February, M y, August, and November.
All toxicity testing results required as part of this permit condition will be entered on the Effluent

STORMWATER MONITO#ING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge: Yastewater and stormwater associated with industrial activity.
Such discharges shall be controlled, limited and monitored as specified below.
The Permittee shall develop a Stormy ater Pollution Prevention Plan, herein after referred to as the
PIan. This Plan shall be considered public information and shall include, at a minimum, the
following items:
a. Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of regulated
stormwater discharges. The sj'te plan shall contain the following:
(1) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name ofl the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system, the
name of the municipi lity and the ultimate receiving waters; and accurate latitude
and longitude of the int(s) of discharge.
2 A narrative description of storage practices, loading and unloading activities,
() P b P g
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practides.
(3) A site map drawn to scale with the distance legend indicating location of industrial
activities (including torage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for ea;:h outfall and
activities occurring in' the drainage area, building locations and impervious surfaces,
and the percentage �ater
f each drainage area that is impervious. For each outfall, a
narrative descriptio of the potential pollutants which could be expected to be
present in the storm discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(�) Certification that the storm\vater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with th� requirements found in Part III, Standard Conditions, Section
B.11.
b. Stormwater Management Plan. The stormwater management plan shall contain a narrative
description of the materialsmanagement practices employed which control or minimize the

exposure of significant materials to stormwater, including structural and nonstructural
measures. The stormwater-management plan, at a minimum, shall incorporate the
following;
(1) A study addressing the technical and economic feasibility of changing the methods
of operations and/or storage practices to eliminate or reduce exposure of materials
and processes to stormwater. Wherever practicable the permittee shall cover all
storage areas, material handling operations, manufacturing or fueling operations to
prevent materials exposure to stormwater. In areas where elimination of exposure
is not practicable, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials,
storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous
materials to prevent leaks and spills from contaminating stormwater runoff. If the
secondary containment devices are connected directly to stormwater conveyance
systems, the connection shall be controlled by manually activated valves or other
similar devices [which shall be secured with a locking mechanism] and any
stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, and visible sheens, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the observation, the
description of the accumulated stormwater and the date and time of the release shall
be kept for a period of five years.
(3) A narrative description shall be provided of Best Management Practices (BMPs) to
be considered such as, but not limited to, oil and grease separation, debris control,
vegetative filter strips, infiltration and stormwater detention or retention, where
necessary. The need for structure: BMPs shall be based on the assessment of
potential of sources to contribute significant quantities of pollutants to stormwater
discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be
taken to limit or prevent erosion associated with the stormwater systems.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan shall
incorporate a risk assessment of potential pollutant sources based on a materials inventory
of the facility. Facility personnel (or team) responsible for implementing the plan shall be
identified in the plan. A responsible person shall be on-site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations.
d. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
program shall be developed. The program shall document schedules of inspections and
maintenance activities of stormwater control systems, plant equipment and systems.
Inspection of material handling areas and regular cleaning schedules of these areas shall be
incorporated into the program.
e. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill"'response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater ninoff. Facility personnel (or
team) responsible for implementing the training shall be identified in the Plan.

Mass/Day Measurements
,,a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or meast red during a calendar month on which daily discharges are
sampled and measure, 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 arid/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.
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

The following comments on Carolina Power & Light (CP&L) Company's Harris Nuclear
Plant/Harris Tarris Energy & Environmental Center draft National Pollutant Discharge Elimination System
(NPDES) permit are submitted pursuant to the North Carolina Division of Environmental
Management's (NCDEN4) letter dated April 10, 1996 whioh was received on April 12, 1996. The
comments address items in the sequence that they appear in the draft permit and are referenced to

CP&L recommends numbering the pages of the final permit to assist in future referencing
of the document,
CP&L hcreby requests spies of the Pact Sheet(s) prepared by the NCL)EM staff to provide
the rationale for the limitations and monitoring requirements included in the draft permit.
The next to last paragraph is inappropriate since discharges of storm water- frorn parking lots
and roof tops aro not subject to regulation and are thus allowed, CP&L proposes the
following language:
.any other wastewater, and stormwater associated with in&atrial activities point
source discharge to surface waters of the state is prohibited unless covered by
another permit, authorization or approval.
A revised storm water map for the facility is attached (Attachment 1) herein as an
amendment to the reap originally submitted with the application for permit renewal. The
revised map'indieates storm water discharges into Harris Lake, but also indicates storm water
discharges into the main intake channel (SWNR-4), the emergency intako channel (SWNR-
6), and the emergency effluent channel (SWNR-7 and SWNR-8). Since storm water
discharges associated with industrial activity are directly regulated only if they discharge to
waters of the US or state waters, CP&L believes that the storm water discharges into those
OV,
MAY 10 '96 12:16PM OPERATIONS & ENVIRONMENT SUPPORT
P.3
channels do not represent discharges into waters of the US or into state waters.
Consequently, the discharges that are not into Harris Lake should not be.regulated.
Additionally, in the preamble to the NPDES storm water application zegs.. (Vol.' SS,
11/16/90) EPA explicitly stated that transformer facilities mere not subject to the phase I
storm water regulations. Consequently, CP&L requests that regulation of this stormwatcr
W
discharge ( SNR -9) be deferred.until it is addressed under phase 11 of the storm water
program.
• CP&L requests that the first paragraph be written as Follows:
Thispermit may be modified, or revoked and reissued to incorporate toxicity limitations and c
monitoring requirements in the eveni toxicity testing or oilier Dertlnent studies conducted on
the effluent or receiving stream indicate decisively shat excursions of the water quality ��
standards fob xicity may be expected in the receiving stream as a result of'this discharge.
• item 2., This monitoring frequency should be reduced to quarterly since there is a large
amount of data already existing on this discharge. - 15� Gtrq oaf l•C,
page
The second to last paragraph on both toxicity conditions, states that the permit may be
reopened to include limits if data indicates potential impacts to the receiving stream. Limits
are justified if there is a reasonable potential for the discharge to cause an, excursion of the
water quality standards for toxicity. Limits may not be justified if there is only a "potential
[adverse] impact." Additionally, this paragraph relates reopening the permit to tests
performed by either CP&L or DEM. CP&L is concerned that if DEM conducts a test which
indicates a potential water quality standard excursion, but CP&L splits the sample and
demonstrates no potential excursion, (or vice versa), this paragraph allows the permit to be
reopened to require a limit. This places CP&L iii a position of having a limit imposed based
on questionable and conflicting data. CP&L requests that the paragraph be rewritten as
follows:
Should test data from either these monitoring requirements or tests performed by the 'elf'" IT
North C'aeolina .Division o, f Environmental Management indicate decisive! that P
there is a reasonable potential for water quality standarcu
ds exrsions in t e I eArll �
receiving stream, this permit may be re -opened and modified to include alternate J
monitoring requirements or limits.
The way the NOTE item is worded on both toxicity conditions, the permittee must submit
suitable test results with the retest or be in noncbmpliance. However, retest conditions may

H.4
also fail due to. oircurnstances beyond the control of the permittee (e.g_, control organism
survival). It is believed that the intent of this paragraph is to require retesting within 30 dans
if a test condition fails, and not the way the paragraph is worded which requires the retest to
be suitable. It sbould be noted that the April 3, 1996 letter to our Cape Fear facility ;from A.
Preston Howard stated that CP&L's interpretation of this paragraph is correct and an invalid �A„ E --
test will not be considered noncompliant if conducted within 30 days. It is recommended
that the last sentence in the paragraph be reworded as follows:
Failure to retest within 30 days of initial moLijWujig gvent will constitute
noncompliance with moniloring requirements.
item 3., The toxicity limitation appears to be an instantaneous maximum value. This limit
should be expressed so that if a test fails, the permittee may resarnple during the month and
still be in compliance if the second test passes. Yids would encourage permittees to quickly
identify and correct the source of toxicity in order to have the opportunity to be in
compliance. If the limitation, is expressed as an instantaneous maximum the permittee has
no incentive to identify and correct the problem in an expeditious manner after a failure
because he will have no opportunity to remain in compliance, 5

Item
Information
1
Discharge Serial No. 006 is specified to maintain consistency with the
outfall numbering used in the current NPDES permit.
3
Engineering drawings, Final Safety Analysis Report, system descriptions,
and other related documents are available upon request.
16
Chemical constituents contained in this discharge that may be conveyed
to Harris Lake will in part be representative of the naturally occurring
chemical quality of the intake water and will also have chemical constitu-
ents of such quality and quantity associated with similar discharges for
nuclear generating facilities of this size, type, and in this geographical
location. Either all or part of the elements listed in the Periodic Table,
either singularly or in any combination, may from time to time be
contained in the discharge.
16
Constituents checked are either 1) present in the common outfall fine as
determined by conventional/priority pollutants monitoring for this permit
application, 2) known to be present in the specific waste streams, or 3)
used in a process which could result in discharge to waste streams.
16
Radioactive components of releases are regulated by the Nuclear Regula-
tory Commission and, therefore, not addressed in this application.
16
Algicide currently used as needed is the biodispersant "ACTI-BROM
1338". Approval for use was granted June 11, 1990 by the North Carolina
Division of Environmental Management. Sodium bromide in other forms
may be purchased from other vendors in the future. Also, gluteraldehyde
is used in closed cooling systems but it is not normally discharged;
however, limited quantities may be discharged due to maintenance or
system leakage.
17
The influent data requested is variable in nature and not normally under the
control of the applicant. Effluent data are partially derived from Discharge
Monitoring Reports previously submitted to DEM. These documents are
incorporated by reference in this submittal. Other effluent data reported
in this application are from Conventional/Priority Pollutants monitoring
conducted at the common outfall during 1995 (Attachment 5).
17
EPA - approved procedures are used for all NPDES -- required analyses.

(approach taken, correspondence with region, EPA, etc.)
As per the permittee's request, this permit will include the Harris Energy & Environmental Center
(currently NC0026735) as Outfall 007. There are no other significant changes recommended at
this time. Outfalls 001- 005 ultimately route through Outfall 006, the combined discharge for the
nuclear power plant. TP and TN monitoring should be dropped from prior outfalls and required
only for 006. Aluminum montitoring should also be dropped. Also per CP&L's request, sample
type for acute toxicity test on Outfall 007 should be changed from Grab to Composite.

that they are performed annually. We may wish to consider including permit language to require
that all such studies be submitted to DEM, when performed.

ACUTE TOXICITY MONITORING (MONTHLY)
The permittee shall conduct acute toxicity tests on a monthly basis using protocols defined as
definitive in E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to
Freshwater and Marine Organisms. The monitoring shall be performed as a Fathead Minnow
(Pimephales promelas) 48 hour static test, using effluent collected as a 24 hour composite.
Effluent samples for self-monitoring purposes must be obtained during representative effluent
discharge below all waste treatment. Tfi first test will be performed within thirty days from the
effective date of this permit.
The parameter code for this test is TAA6C. All toxicity testing results required as part of this,
permit condition will be entered on the Effluent Discharge Form (MR 1) for the month in which it
was performed, using the appropriate parameter code. Additionally, DEM Form AT -1 (original) is
to be sent to the following address:.

Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management indicate potential impacts to the receiving stream,
this permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions' as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test

ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The permittee shall conduct acute toxicity tests on a quarterjy basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent
Concentration." The monitoring shall be performed as a Fathead Minnow (Eigephales promelas) 24 hour static
test, using effluent collected as a 24 hour composite. The effluent concentration at which there may be at no time
significant acute mortality is 90% (defined as treatment two in the North Carolina procedure document). Effluent
samples for self-monitoring purposes must be obtained during representative effluent discharge below all waste
treatment. The first test will be perfo med after thirty days from the effective date of this permit during the
months of "L /A^, . ►A oJ.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR -1) for the month in which it was performed, using the parameter code TGE6C.
