Wasteload Allocation Summary
(approach taken,correspondence with region, EPA,etc.)
Limits are set as per Federal Effluent Guidelines in 40 CFR 423.13 (b) for Steam Electric
Power Plants. The followi�n outfalls are included in this fact sheet: 001 - Cooling Lake,
002 -Old Ash Pond,003'NvIetal Cleaning Wastes, 004 -New Ash Pond. Outfall 001 is to
the Cape Fear River but is episodic occurring once or twice a year at up to 250 MGD for
one to five days. Outfalls 002&004 are to the Cooling Lake. Outfall 003 discharges to
the ash pond. Acute Toxicity Test species was changed in 9/94 to achieve consistency with
other episodic discharges and to protect against potential toxicity caused by large slugs of
nitrogen in the river from this discharge.

Facility Name CP&L-Sutton Steam Electric Plant Permit# NC0001422 _Pipe# 001 _
ACUTE TOXICITY MONITORING (MONTHLY)
The permittee shall conduct acute toxicity tests on a mond* 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 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:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Rd.
Raleigh, N.C. 27607
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
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

Facility requesting renewal of existing NPDES permit. Has four outfalls with only one
discharging directly to State surface waters,other wastestream discharge to CP&L Cooling
pond. Last WLA was completed 1 year and 3 months ago in 9/94 by J. Doll.Thorough
review of CP&L outfalls and discharge was given at that time. Outfall 001 is an episodic
discharge and most recently discharged in February 1995,previous discharge occurred in
Sept. 1992.Existing limits based on effluent guidelines and review of monitoring data.
Discharge from CP&L includes recirculated cooling water,coal pile runoff,Storm water
runoff, ash sluice water for the new ash pond,domestic wastes,and low-volume wastes
(includes plant drains,which convey miscellaneous equipment leakage,equipment drainage
for maintenance,equipment washdown water,sampling streams,service water system
blowdown,and water treatment wastes. Also chemical metal cleaning wastes,ash
reclamation,and fire water system.
Outfall 001 - Cooling lake discharge.

MEMORANDUM
To: Ed Beck
Wilmington Regional Office
From: Greg Niziclj
Permits and Engineering
Subject: Draft Permit Meeting
Permit#NC0001422
CP&L,Sutton Plant
New Hanover County
Coleen,Jason and I met this morning with CP&L to discuss their draft permit. The
following issues were raised:
1) Outfall 001 -
•They requested that the Toxicity test sample type be changed back to a"grab" as in
the old permit. Ricky Miller said the pond's detention time was of such a large
duration that a grab sample was representative of the discharge. They also said that
the outfall to the River was at the end of the lake far away from any incoming waste
streams. We agreed to this change.
• Special condition "Q" was clarified. The instream monitoring will not be required
as part of this permit once the Technical Committee's program begins sampling. This
will be clarified in the final permit.
2) Outfall 002-
•pH limits should be dropped. CP&L will furnish EPA documentation stating that
the cooling lake provides neutralization and that it is permissible to apply pH limits at
the cooling lake discharge. We agreed to only require monitoring at the ash pond.
•Monitoring location ("E") mistakenly omitted for copper. This will be corrected.
3) Outfall 003 -
•In the heading of the effluent sheet the discharge description should be corrected to
say that discharge is to the ash pond, not the cooling pond.
•The limits for oil& grease and TSS are covered at the ash pond. They will be
removed from this outfall.

I ,
outfall 003 (continued)
•pH does not need to be limited here since discharge is to the ash pond. Monitoring
only will be required.
•The footnote (**)for computing mass limits will be removed. Meeting the
concentration limits will be sufficient.
4) Outfall 004-
•pH will be changed to monitoring only as previously discussed for 002.
•Monitoring location("E") will be added for copper.
5) Special Conditions-
• "G" & "H" regard capacity of ash ponds. Since CP&L has submitted information
with the application showing that they have sufficient storage in both ash ponds to
meet the storage requirements,these conditions will be removed from the permit.
CP&L will send an EPA memo citing guidance for this methodology. They will
provide the storage computation on subsequent permit renewals.
• "I" addresses hazardous waste combustion. They requested that this be removed.
Mick Greeson said that the solvents burned are classified as hazardous because of
their combustibility and not due to toxic concerns. He said after being burned, they
are no longer"hazardous" and that this condition does not really apply. Dropping this
condition seems reasonable.

CP&L-SUTTON ELECTRIC PLANT JMN
CAPE FEAR RIVER 1/4/96
030617
Facility requesting renewal of existing NPDES permit Has four outfalls with only one
discharging directly to State surface waters,other wastestream discharge to CP&L Cooling
pond. Last WLA was completed 1 year and 3 months ago in 9/94 by J. Doll. Thorough
review of CP&L outfalls and discharge was given at that time. Outfall 001 is an episodic
discharge and most recently discharged in February 1995,previous discharge occurred in
Sept. 1992. Existing limits based on effluent guidelines and review of monitoring data.
Discharge from CP&L includes recirculated cooling water,coal pile runoff, Storm water
runoff, ash sluice water for the new ash pond,domestic wastes,and low-volume wastes
(includes plant drains,which convey miscellaneous equipment leakage,equipment drainage
for maintenance,equipment washdown water,sampling streams,service water system
blowdown,and water treatment wastes. Also chemical metal cleaning wastes,ash
reclamation,and fire water system.
Outfall 001 - Cooling lake discharge.

Sony for not getting back to you on this. I talked with Jason awhile back on these and we
decided that we could probably go along with their requests if the same parameters are being
sampled before discharging to the stream. Also,I tried to find out why the temperature
narrative was for SC waters and nothing in our files showed why.In fact the narrative on
the the 1989 WLA was for C waters.We wondered if it had been changed because of its
proximity to SC waters but found no info concerning it. So,unless P&E have some reasons
for the monitoring remaining the same,we will concur with CP&L's requests for revision.

To:Jackie Nowell
From my superficial knowledge of the facility and their discharge scheme,none of these
requests seems unreasonable to me. Maybe we should change the TP/TN monitoring
language to require it"once per discharge event but not to exceed 4 times per year. Maybe
that would satisfy their concerns. I have no other particular concerns on these monitoring
issues,and I'm perfectly comfortable leaving them at you and Greg's discretion. Keep me
posted as to what comes out of it.

FYI and I need your input on whether you have any concerns with these frequencies being
dropped or modified. On item 2,I tried find out how this temp statement was given,no luck
so far. When you get a second or two,let me know.

I rec'd 7 pages from them on this facility. The items below involved WLA issues. I can
provide a copy of their letter if you would prefer.
1)Outfall 001. They would like monitoring freq. for TP and TN reduced to semi-annual or
annual. CP&L said lake sampling data was obtained in 1993 indicating levels of TP and TN
(<0.5 mg/1)in the cooling lake to be lower than what is in the Cape Fear. Since this lake

Pepe 2
discharges less than once/yr. this doesn't seem to really matter,but as usual,it does to them.
2) 001 -The temp language(0.5°C increase)seems to be for SC waters. Shouldn't this
language be changed to match the C waters version?
3) Outfalls 002 and 004-Requesting qtrly metals monitoring(4 parameters)be dropped
since this is an internal outfall and these same parameters are all monitored at 001 into the
Cape Fear.
4)Outfalls 002,003 and 004- Want 2Jmo pH monitoring dropped since this parameter is
limited at 001. Reasoning is that the lake is considered a treatment unit in neutralization of
pH,so even if abnormal levels were measured at these internal outfalls,CP&L would claim
that the Lake provides treatment and therefore the high/low values were not a concern.

it hasn't been drafted yet-you finished it way ahead of the basin schedule-so the change
shouldn't be a problem.

To:Greg Nizich
Cc:Carla Sanderson
File(s): CP&L.SUTTON.TOX
Following up the phone message,I left for you today.
Kristy Roberson of AQ TOX called me and said that the enclosed tox form would be more
appropriate for this facility . Said that it would be more consistent with tox tests for other
episodic discharges.I think that she also said that after the first five discharges are taken,it
will changed to an annual test. If you have already drafted this,will this be a major problem
with CP&L? I saw the 10/6/94 memo to Ed Beck about the old tox test being changed to
"grab", there was no comment about the type test.
Let me know if questions.
