Add Info Letter
Laurie,
Thank you for taking time to show us around the facility.
Based on our site visit on September 27, 2014, DEMLR concurs:
1. Stormwater outfalls SW4, SW5 and SW6 on the Front Access Road are not associated with industrial activities.
2. Outfall 003 can be used as a representative outfall for SW1, SW2 and SW3. Sampling SW3 will be adequate for
the application.
3. Given the nature of the industrial activity associated with SW1, SW2, and SW3, there is no reason to suspect
that SW1, SW2 or SW3 would include PCBs. Disregard the request "Please provide details (dates, location on
site, drainage area impacted, etc.) about the presence or any past storage and/or releases of polychlorinated
biphenyl compounds (PCBs) on site. If there were any known releases, please discuss actions taken to
remediate any areas affected. Include information about what drainage areas might have been impacted by
PCBs.,
If Duke Energy concurs, please concur in your response to our request for additional information dated August 26, 2014.
Also, the SWPPP indicates that vehicle wash station is a Best Management Practice. My understanding is that the
vehicle wash station was installed for the airport project. DEMLR expects Duke Energy to continue to maintain and
operate the vehicle wash station during industrial activities on the access road even after the airport project is
completed. If Duke Energy concurs, please concur in your response to our request for additional information dated
August 26, 2014.

Asheville Steam Electric Plant
Buncombe County
Dear Mr. Sideris:
The Division of Energy, Mineral and land Resources' Stormwater Permitting Program (SPP) received an
application for an N PDES stormwater permit for this facility on July 31, 2014, We need additional information
from the company to continue processing that application and developing a draft permit.
The submittal included copies of EPA Forms 1 and 2F originally signed in 2010. The transmittal letter
referenced the formal name change of the Owner from Progress Energy Carolinas, Inc. to Duke Energy Progress
Energy, Inc. ("Duke"). We understood that Duke would submit a revised application for an NPDES Stormwater
permit. We request that Duke re -submits updated EPA Forms 1 and 2F with appropriate signatures.
Thank you for providing more recent copies of the annual certification all outfalls had been inspected for
non-Stormwater discharges. All of the certifications indicated that no discharges were occurring during periods
of no precipitation. For future reference on other applications for this facility or other Duke facilities, if
any outfalls were not observed, or they included non-stormwater flows, please amend your EPA Form 2F
to report that. Also, if any discharges have occurred during dry periods, be sure to indicate in the
application how those discharges are or will be permitted.
Analytical sampling results were provided only for Stormwater outfall SW-3 (March 2010 sample).
Results for other outfalls were not provided, our understanding was that Duke would follow the same format as
the Rlverbend application in subsequent application submittals, Including sample results from all stormwater
discharge outfalls. We understand only SW-3 was sampled for past NPDES discharge Its
renewals for this
plant; however, we did not discuss an arrangement for sampling fewer outfalls for this Individual stormwater
permit application. Please provide sampling results for the other five outfalls at this site, or provide a
schedule for sampling those outfalls. If sampling cannot be done at one or more outfalls, please clarify the
circumstances that indicate sampling is not appropriate at this time.
Please provide details (dates, locations on site, drainage areas impacted, etc.) about the presence
or any past storage and/or releases of polychlorinated biphenyl compounds (PCBs) on site. If there were
any known releases, please discuss actions taken to remediate any areas affected.Include information about
what drainage areas might have been impacted by PCBs. Received

The application included a small 8" x 10" map of stormwater drainage areas. The map was not legible,
and it did not include drainage areas for all the stormwater outfalls listed in the application. Please provide a
plan size (nominally 24" x 36") site drainage map clearly showing all drainage areas and other items listed in
Section III of EPA Form 2F,
We anticipate that the closure of this site's ash ponds may soon be underway, and that the activity may
be begun and completed within the term of the stormwater permit. We would expect that some aspects of the
ash pond closure activity may present the potential for stormwater pollution (for example, activities such as
transport of ash along on -site haul roads.) in so far as is possible at this point in time, please provide
Information on ash pond closure that could inform our drafting of the stormwater permit. Aspects such as
the location of haul roads, time schedules, and site modifications necessary to accomplish the undertaking would
help us assess how the permit should address the stormwater risks from the activity.:
We are asking that Duke provide this information by September 22, 2014. Otherwise we will return
the application as Incomplete. Also, please provide an electronic copy of all application materials, including
this additional information, along with your submittal. If you have any questions about this matter, please
contact me at [phone] or [e-mail]. or Bethany Georgoulias at [phone] or

Qualitative monitoring requires a qualitative inspection of each stormwater outfall, regardless of
representative outfall status, for the purpose of evaluating the effectiveness of the Stormwater
Pollution Prevention Plan and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls.does not need to be performed
during a representative storm event.

DWQ staff were accompanied by Progress/Duke staff members: Laurie Moorhead, Shannon Langley and
John Toepfer
Beginning at the Outfall 001, DWQ staff travelled south along the French Broad River to the approximate
Progress Energy property boundary, identifying surface water features, including seeps, wetlands, and
intermittent and perennial streams. For the purposes of this survey work, official stream and wetland
identification methods were not employed; best professional judgment and professional knowledge were
utilized.
In general, the area of interest is a riverine complex of seeps, wetlands, and intermittent and perennial
streams, including marsh, basins and depressions within the floodplain of the French Broad River.
The two coal -ash -pond, engineered seep discharges were identified. The 1964-pond discharge enters a
discrete stream channel west of Interstate 26 and the 1982-pond discharge enters the wetland complex
west of Interstate 26.
Multiple points of surface water discharge to the French Broad River were identified, which consisted of
stream channels as well as overflow channels from wetlands.
At the time of the site visit, the French Broad River valley had experienced above -average rainfall over the
preceding couple of months providing abundant ground and surface water in the area being surveyed.

Form 2C - Item II-B Flow, Sources of Pollution, and Treatment Technologies
The Asheville Steam Electric Plant is located in Arden, North Carolina south of Asheville, North
Carolina. The Asheville Steam Electric Plant is a coal-fired, steam cycle electric generating
E}
I} plant with two generating units. Two Internal Combustion (IC) Turbines are also located on the
plant site. The plant has a 320-acre cooling lake (take Julian) on the east side of the French
Broad River in Buncombe County, North Carolina.
Chemical constituents contained in the discharges from this plant will, in part be representative
of the naturally occurring chemical quality of the intake water and will also have chemical
constituents of such quality and quantity associated with similar discharges for fossil generating
facilities of this size, type and in this geographical location. Either all or part of the elements
listed on the Periodic Table, either singularly or in any combination, may from time to time be
contained in the discharge.
Outfall 001 - Discharge from Ash Pond to French Broad River
The Plant's ash pond (hereinafter referred to as the 1982 ash pond), is located east of the
French Broad River, south of the plant and discharges into the French Broad River. The ash
pond receives ash sluice water, various low volume wastes, coal pile runoff, limestone pile
runoff, gypsum pile runoff, air pre -heater cleaning water, fire protection system drainage,
chemical metal cleaning wastes (potentially), storm water and other waters from the
Combustion Turbine Facility on the Plant's site. Wastewater from the plant's truck wash and
weigh stations also are directed to the plant's 1982 Ash Pond. Accumulated water within the
boundaries of the old ash pond (hereinafter referred to as the 1964 ash pond) may also from
time to time be transferred to the 1982 pond. The plant will also be considering installation of a
reverse osmosis system to treat water for plant process uses. Reject water from this plant
process system will be sent to the ash pond. The pond provides treatment by sedimentation
and neutralization to the above -referenced individual waste streams. Water leaves the 1982
ash pond via a standpipe with skimmer and flows by pipe and lined ditch to a secondary basin,
where it is discharged by overflow to a ditch that coveys it to the French Broad River. Toe

drains from both the 1982 pond and the 1964 pond drain to the French Broad River. Detailed
• descriptions of the individual waste streams are below.
J
Ash Sluice Water
i Fly ash and bottom ash from both units are hydraulically conveyed by an ash sluice pipeline to
the ash pond. As needed, alum is added to the ash sluice influent to aid settling. A Selective
Catalytic Reduction system (SCR) is operated on both Unit 1 and Unit 2 for NOx emissions
control. Urea is injected to reduce NOx emissions. A byproduct of this process is an "ammonia
slip" which will be carried to the 1982 ash pond via ash sluice water. As necessary, a system to
mitigate SO3 emissions may also inject additional ammonia into the combustion process. This
mitigation system has not been needed to date but may become necessary as fuel sources
change. Various boiler sediments and ash accumulations collected during maintenance
activities may also be transported to the 1982 ash pond. The ash pond discharge flows into
the secondary settling pond where it combines with the FGD treated wastewater prior to
discharging to the French Broad River. Progress Energy plans to relocate this secondary
settling pond and discharge point during the term of this permit to facilitate modifications
designed to enhance the 1964 ash pond dam's safety factor.
Coal Pile Runoff
Storm water runoff from the coal pile is collected in drainage ditches that surround the coal pile.
The drainage ditches are routed to the 1982 ash pond for treatment. During maintenance
activities, sludges removed from catch basins, sumps, etc. may be transported to either the
1982 ash pond or the 1964 ash pond for disposal.
Limestone and Gypsum Piles Runoff
Storm water runoff from the limestone and gypsum piles is collected in drainage ditches which
are routed to the 1982 ash pond for treatment. During maintenance activities, sludges removed
from catch basins, sumps, etc. may be transported to the 1964 ash pond and/or the 1982 ash
pond for disposal.
Storm Water
Storm water runoff from the plant area, parking lots, combustion turbine area, oil storage and
k handling facility and the plant's substations is routed to the ash ponds for treatment. During
2

maintenance activities, sludges removed from catch basins, sumps, etc. may be transported to
the 1964 ash pond and/or the 1982 ash pond for disposal.
Low Volume Wastes
Boiler water make up is withdrawn from Lake Julian and purified utilizing vendor supplied
equipment. Boiler water is treated with ammonia, hydrazine, and sodium hydroxide. Boiler
i
blowdown and drainage is sent to the ash pond and may contain small quantities of the
chemicals. A new Reverse Osmosis system or alum coagulation/filtration service will be used
j in conjunction with the vendor supplied equipment to provide water for various plant processes.
The reject stream from the Reverse osmosis unit will be sent to the 1982 ash pond. .Some
molybdate waste from the closed cooling water system is created through valve leakage and
maintenance activities and is discharged to the 1982 ash pond. A furnace ash hopper seal is
maintained by using plant service water. A standard operation water level is maintained in a
seal trough for the ash hopper seal. Overflow from this trough is discharged to the 1982 ash
{ pond. A sodium hydroxide solution is fed into this flow stream as necessary for ash pond pH
adjustment. Sulfuric acid is fed to the ash sluice water as necessary for 1982 ash pond pH
adjustment. Coal dust suppression is achieved by spraying a proprietary chemical on coal at
different stages of coal use. Small amounts of excess dust suppression chemical have the
potential to be discharged to the 1982 ash pond via plant drains or coal pile runoff. Small
amounts of urea waste from bulk urea unloading operations are discharged to the 1982 ash
pond. All plant area floor drains are routed to the 1982 ash pond and include equipment
drainage and wash down along with rainfall runoff. During maintenance activities sludges
removed from catch basins, sumps, etc. may be transported to the 1982 ash pond and/or the
1964 ash pond for disposal.
In many cases, added chemicals are consumed or chemically altered during the plant
processes. Only trace amounts might be recoverable in water entering the 1982 ash pond.
Detectable levels of these chemicals would not be expected to occur in ash pond discharges.
Flue Gas Desulfurization_Blowdown (Low Volume Waste)
' The Flue Gas Desulfurization (FGD) system directs flue gas into an absorber where a limestone
{calcium carbonate) slurry is sprayed. Sulfur dioxide in the flue gas reacts with the limestone to
produce calcium sulfate (gypsum). This system reclaims any unreacted limestone slurry to be
3

Carolina Power & Light Compar,,. 0
Asheville Steam Electric Plant
National Pollutant Discharge Elimination System Permit Number NCO000396
reused in the absorber. A small blowdown stream is used to maintain the chloride
- concentration in the reaction tank. The blowdown stream is passed through a clarifier to
remove solids and the chloride concentration in the waste stream is diluted using water from
Lake Julian. Chemicals are used to adjust pH and to aid solids removal in the clarifier. A
constructed wetland is used to remove metals, mercury and selenium specifically, and the
treated wastewater is discharged into the secondary settling pond.
Air Preheater Cleaning (Low Volume Waste)
4
The air preheater will be water washed once per year or more frequently as needed. The
ill
wastewater from this activity will be discharged to the 1982 ash pond.
i
3
Chemical Metal Cleaning Wastes
The boilers are chemically cleaned every five -to -eight years using Tetraammonia ethylene
diamine tetraaccetic acid (EDTA) solution. This cleaning solution and its rinses are stored on
site for disposal by evaporation in an operating unit's furnace. Typical cleanings would result in
a waste of approximately 80,000 gallons. Should evaporation not be used, the wastewater can
be treated by neutralization and precipitation prior to being conveyed to the 1964 ash pond, or
to the 1982 ash pond, or other means of disposal. Cleaning of other heat exchanger surfaces
may produce 5,000-10,000 gallons of wastewater every three -to -five years.
Other Wastes
Operation of the combustion turbine (CT) generation facility may produce turbine blade wash
water, inlet filter cooling water, various condensate waters, and water from equipment and tank
drains. These wastewaters will be collected in the storm water collection system of the CT site
and routed to the 1982 ash pond. During maintenance activities, sludges removed from catch
basins, sumps, etc. may be transported to the 1964 ash pond and/or the 1982 ash pond for
disposal.
Plant Potable and Sanitaly System
The supply of water for plant potable and sanitary use is obtained from the Asheville/Buncombe
Water Authority system and waste from this system is discharged to the Metropolitan Sewage
District System.

I Herbicide and Pesticide Usage in the Treatment System Ponds
Herbicides may be used as needed to control nuisance aquatic vegetation. These herbicides
1 are applied by licensed applicators, or persons under the immediate supervision of a licensed
applicator, in accordance with the manufacturer's instructions. Pesticides may be used as
needed to perform biological assessments. These Pesticides are applied by licensed
applicators, or persons under the immediate supervision of a licensed applicator, in accordance
with the manufacturer's instructions.
230 KV Substation Storm Water
Storm water runoff from the substation located adjacent to the plant is conveyed to the 1964
ash pond. This water may be transferred to the 1982 ash pond as needed to maintain
appropriate water levels in the 1964 ash pond.
Outfall 002 - Discharge to lake Julian
Once -Through Cooling Water
This flow provides condenser cooling water for the generating units 1 and 2. Maximum
condenser flows for units 1 and 2 are 150 MGD and 156 MGD, respectively.
Once -through cooling water is used to supply non -contact cooling water for the component
closed cooling water system. The component closed cooling water system flows combine with
unit 1 and 2 condenser flows prior to discharge to Lake Julian. Maximum component closed
cooling water system flows for unit 1 and 2 are 9.1 MGD and 10.2 MGD, respectively.
Discharge flow to Lake Julian is calculated at the intake to units 1 and 2 condensers and to the
circulating water to the heat exchanger. The discharge of water from the heat exchangers is
routed to an ash sump. The majority of this water is further routed to the discharge of units 1
and 2 condensers. Less than one percent of the flow to the ash sump is used to supply ash
sluice water, preheater cleaning water, and fire protection water.
Control of biological fouling on heat -exchanger surfaces is accomplished by addition of sodium
hypochlorite as required, which is usually less that 2 hours per day per unit, with a net total
residual chlorine of less than 0.2 ppm discharged during that period. Cooling is accomplished
by evaporation from the surface of Lake Julian and mixing and convection with lake waters.
Make up for Lake Julian is from the French Broad River, natural runoff and creek flows. Water

Form 2F - Item IV B. Narrative Description of Pollutant Sources
Various products and waste products will enter and leave the plant via the old access
road, new access road and rail line. The enclosed site drainage maps display the
sections of the site access roads from which storm water will discharge to Lake Julian
or an unnamed tributary of Powell Creek which discharges into the French Broad River.
Storm water from other sections of the roads flows via sheet flow or is conveyed to the
1982 ash pond or to the hot pond prior to discharging to, respectfully, the French Broad
River and Lake Julian. The discharges from the hot pond and 1982 ash pond to Lake
Julian and the French Broad River, respectively, are NPDES permitted discharge
outfalls.
New Access Road
The portion of the road from which storm water will discharge directly to Lake Julian is
divided into 3 separate drainage areas, each with an outfall. Storm water that is routed
to SW-1 is carried to Lake Julian using piping, grass -lined ditches, concrete -lined
j ditches and sheet flow. The area drained contains Carolina Power & Light Company
( d/b/a Progress Energy Carolinas, Inc. (PEC) property, non-PEC property, the access
road and a railroad storage yard where coal -filled rail cars can be stored. Storm water
that is routed to SW-2 will be collected in a riprap-lined ditch that will then allow sheet
flow to Lake Julian. The area drained contains only the access road. Storm water that
is routed to outfall SW-3 will be routed through piping and both grass and riprap-lined
ditches. The area drained to SW-3 includes PEC property, non-PEC property, the
I access road, and the railroad storage yard. PEC can only provide a rough estimate of
impervious area for the property not owned by PEC.
The property used for the new access road was purchased by PEC. The past use of
this property was residential; therefore, PEC has no knowledge of any significant
materials that have been treated, stored or disposed on this property in the past. PEC
staff performed a limited Phase 1 Environmental Site Assessment on this property and
found no visual evidence of the storage, use, or disposal of chemicals or hazardous
I substances. Any chemicals used are likely limited to consumer products in limited
quantities. PEC has stored in the past and will store in the future coal at the railroad
storage yard. The coal is contained in rail cars that are waiting to be unloaded at the
plant. Other than the coal stored at the railroad storage yard, PEC has not treated,
stored or disposed of any significant materials on any property already owned by PEC
in the drainage area of this access road and has no plans to treat, store, or dispose of
significant materials on this access road or on immediately surrounding property owned
' by PEC in the future. No materials loading or unloading activities will take place on the
access road, railroad storage yard, or on immediately surrounding property owned by
PEC. Various brands of commercial herbicides (i.e., Roundup, Crossbow) might be
used to control weeds and other unwanted plant growth for security reasons. These
herbicides will be carefully applied by licensed applicators, or persons under the
immediate supervision of a licensed applicator, in accordance with the manufacturer's

,'arolina Power & Light Compan _i

I National Pollutant Discharge Elimination System Permit Number NC0000396
instructions. Fertilizers, pesticides (other than herbicides), and soil conditioners will not
be used by PEC. No hazardous waste treatment, storage, or disposal will occur on this
property.
Old Access Road
The portion of the road from which storm water will discharge directly to Lake Julian is
divided into 3 separate drainage areas each with an outfall. Storm water that is routed
to SW-4 flows over grass -lined ditches and gravel to Lake Julian. The area drained
contains PEC property, non-PEC property, and the old access road. Storm water that
is routed to SW-5 is collected in a grass -lined ditch that discharges into a concrete
conveyance that discharges into the Lake Julian spillway. The spillway discharges to
an unnamed tributary of Powell Creek which discharges to the French Broad River.
The area drained contains only PEC property, including the access road. Storm water
that is routed to outfall SW-6 is conveyed through grass -lined ditches and piping to
Lake Julian. The area drained contains PEC property including the access road and a
picnic area with several buildings and a shelter.
PEC has not treated, stored or disposed of any significant materials on property owned
by PEC in the drainage area of this access road and has no plans to treat, store, or
dispose of significant materials on property in the drainage area owned by PEC. No
materials loading or unloading activities will take place on the access property owned by
PEC. Various brands of commercial herbicides (i.e., Roundup, Crossbow) might be
used to control weeds and other unwanted plant growth for security reasons. These
herbicides will be carefully applied by licensed applicators, or persons under the
immediate supervision of a licensed applicator, in accordance with the manufacturer's
instructions. Fertilizers, pesticides (other than herbicides), and/or soil conditioners will
not be used by PEC in this drainage area. No hazardous waste treatment, storage, or
disposal will occur on PEC property in this drainage area.

Dear Ms. Wilson:
In response to your request for, low -flow data, the U.S. Geological Survey (USGS) does not
have site -specific, low -flow discharge data for French. Broad River at NC 280 near Skyland,
NC (station id 03447840, drainage area 660 m12).. The low -flow characteristics that are pro-
vided on the attached sheet have been computed by correlating the runoff characteristics of a
nearby continuous -record gaging station upstream of the request site. - Please note that the flow
estimates do not specifically account for the presence of any diversions or regulation, present
or future, which may occur upstream of the request site. Because a similar request for the
1Q10 low -flow discharge was roceived about the same time from Progress Energy, this low.,
flow statistic is included on the attached sheet,
Low -flow characteristics were analyzed using straamflow reoords from a continuous -record
gaging station on the French Broad River near Pletcher, operated since July 2001 and located
upstream at Secondary Road 1419 (station id 03447840, drainage area 6401ni2). Because of
the short period of record at the Fletcher gage, low -flow analyses at this gage were completed
by correlation analyses using two other gaging stations having long periods of record (station
id's 03443000 and 03451500). Then, using the difference in drainage areas between the
request site and the Pletcher gage, low -flow characteristics at the request location were deter-
mined using the low -flow yields, (expressed as flow per square mile drainage area) at the
Pletcher gage. The.estimated 7Q10 discharge is 306 fts/s and is lower than the estimate pro.
vided to you in an e-mail dated January 14, 2004.
Analyses of low -flow characteristics at all three gaging stations indicates a degreasing trend
in low -flow yields between the gages at Blantyre and Asheville. Between these two locations,
the river is affected by some diversions occurring in tributaries along with regulation by small
upstream reservoirs and a power plant located about 8 miles upstream of Blantyre, The anal-
yses indicate that most of the decrease in law -flow yields occurs between the Blantyre and
Fletcher gages.
The table shown on the accompanying page summarizes the low -flow characteristics at the
gaging stations used in the analyses. As previously discussed in January, the French Broad
River downstream from Blantyre is affected by some regulation and diversions. The low -flow
discharge values are based on streamflow records available through September 2003, and the
associated low -flow yields for each value is listed to provide insight in the changing low -flow
yields between file gages.

Dear Ms. England,.
In response to your request for low -flow data, the U.S. Geological Survey (USGS) does not have Oita -specific,
low -flow discharge' data for French goad River at NC 280 near Skylaud, NC (station id 03447840, drainage
area 60 m!). The low -flow characteristics that axe provided on the attached sheet have been computed by
correlating the runoff characteristics of nearby continuous -record gaging station upstream of the request site.
Please note that the flow estimates do not specifically account for the presence of any diversions or regulation,
present or future, which may occur upstream of the request site. Because your request was received about the
same time as a similar request from the N,C, Division of Water Quality (DWQ), the low -flow statistics esti-
mated for the DWQ are Included on the attached sheet,
Low -flow characteristics were analyzed using streamflow records from a continuous -record gaging station on
the French Broad River near Pletcher, operated since My 2001 and located upstream at Secondary Road 1419
(station id 03447840, drainage area 640 mi�. Because of the short period of record at the Pletcher gaga, low -
flow analyses at this gage were completed by correlation analyses using two other gaging stations having long
periods.of record (station id's 03443000 and 03451500). Then, using the difference in drainage areas between
the request site and the Fletcher gage, low -flow characteristics at the request location were determined using
the low -flow. yields (exZt ssed as flow per square mile drainage area) at the Fletcher gage. The estimated
1Q10 died arge is 282 fVls and is lower than the estimated 7Q10 discharge of 306 ft31s.
Analyses of low -flow characteristics at all three gaging stations indicates it deareasing trend in low -flow yields
between the gages at Blantyre and Asheville. Between these two locations, the river is affected by some diver.
sions occurring in tributaries along with regulation by smati upstream reservoirs and a power plant located
about 8 miles upstre= of BIantyre. The analyses Indicate that most of the decrease in low -flow yields occurs
between the Blantyre and Fletcher gages.
A charge for accessing and processing Information has been assessed to partially offset these costs. Your
requested data and as invoice covering processing costs for those data are enclosed. Please forward the orlg-
inal bill with your check to the U.S. Geological Survey,12201 Sunrise valley Drive, MS 271, Reston, Virginia

Proposed conceptual relocation route of outfall 001

Pro osed relocation of outfall 001
In order to facilitate enhancements to the 1964 ash pond dam, it will be necessary to relocate the
existing settling basin and discharge outfall 001. The Asheville Steam Electric Plant is located in close
proximity to the French Broad River but has limited access to the river because of Interstate 26. In order
to relocate outfall 001, it will be necessary to go north approximately 3000 feet to a point where existing
access under the Interstate is located. This proposed discharge location is on property owned by
Progress Energy. The entire span of property. between the existing outfall and the proposed outfall is
also owned by Progress Energy.
d
In addition to the current flows from the 1982 ash pond, a "new" flow will be added to the relocated
outfall. This flow will consists of stormwater and ground water seepage that currently flows into the
1964 ash pond.- Historically, this flow has been allowed to evaporate and/or infiltrate. The
I enhancements to the 1964 pond require that this water level be managed and maintained below a
3 certain elevation. Therefore, it may be necessary to periodically pump water from the 1964 ash pond to
the combined, relocated settling basin and outfall 001. A sample of the water from the 1964 ash pond
' I was taken as part of the preparation of this application. Results from that sampling analysis are
attached.

Application for Permit to Discharge Storm Water Associated with Industrial
Activity
Mr. Belnick:
In an application package dated July 31, 2000, it was disclosed that there were three
stormwater outfalls on the old access road at the Asheville Plant that had previously not been
discovered. In this application package stormwater data in section VI1 of EPA Form 2F was
given for Mayo Steam Electric Plant (NPDES Permit NC0038377), a similar discharge, because
data were not available for the stormwater outfalls at the Asheville Plant. Plant personnel began
immediately monitoring rain events so that sections VII and IX of EPA Form 2F could be
completed with data from a storm event at Asheville Plant. On July 3, 2001, stormwater
samples were collected from SW-5. Unfortunately only forty-four hours, not the required
seventy-two, had passed since the previous rain event of 0.1 inches occurred. Enclosed is EPA
Form 2F in triplicate for the rain event on July 3, 2001.
If there are any questions regarding the enclosed information, please contact Louise England at

Item llf - Site Drainage Map
The enclosed site drainage map is for the section of roadway from which storm water is
conveyed to either Lake Julian or an unnamed tributary of Powell Creek which
discharges into the French Broad River. Storm water from other sections of the road
flows via sheet flow or is conveyed to the ash pond which discharges to the French
Broad River via a NPDES permitted discharge outfall. The portion of the road from
which storm water will discharge to Lake Julian or to the unnamed tributary of Powell
Creek is divided into 3 separate drainage areas each with an outfall. Storm water that
is routed to SW-4 flows over grass -lined ditches and gravel to Lake Julian. The area
drained contains CP&L property, non-CP&L property, and the access road. Storm
water that is routed to SW-5 is collected in a grass -lined ditch that discharges into a
concrete conveyance that discharges into the Lake Julian spillway. The spillway
discharges to an unnamed tributary of Powell Creek which discharges to the French
Broad River. The area drained contains only CP&L property, including the access road.
Storm water that is routed to outfall SW-6 is conveyed through grass -lined ditches and
piping to Lake Julian. The area drained contains CP&L property including the access
road and a picnic area with several buildings and a shelter.
CP&L has not treated, stored or disposed of any significant materials on property
already owned by CP&L in the drainage area of this access road and has no plans to
treat, store, or dispose of significant materials on property in the drainage area owned
by CP&L. No materials loading or unloading activities will take place on the access
property owned by CP&L. Various brands of commercial herbicides (i.e., Roundup,
Crossbow) might be used to control weeds and other unwanted plant growth for
security reasons. These herbicides will be carefully applied by licensed applicators, or
persons under the immediate supervision of a licensed applicator, in accordance with
the manufacturer's instructions. Fertilizers, pesticides, and/or soil conditioners will not
be used by CP&L in this drainage area. No hazardous waste treatment, storage, or
disposal will occur on CP&L property in this drainage area.

Item IV C
No conventional treatment will be provided for the storm water drained from Outfalls
SW-4, SW-5 and SW-6. Prior to discharging to Lake Julian and the unnamed tributary,
storm water from all three outfalls will flow over a vegetative buffer which will provide
some filtering of sediment from the storm water.
All coal trucks that travel on the access road are required to be covered which will
reduce, the spillage of coal on this road. These same trucks are requested to wash
down their wheels prior to exiting the site. The wash water from these wheel washes is
discharged to the ash pond for treatment.
During maintenance activities, sludges removed from ditches or manholes may be
transported to the old and/or new ash pond for disposal.

Mr. Weaver:
CP&L will begin construction of a new access road to the Asheville Steam Electric Plant
in the second quarter of 2000. This road will be the primary route used by coal and oil
delivery trucks and will also be used to transport reclaimed ash. Construction is
expected to be completed by the end of the third quarter of 2000. Asheville plant would
like to begin using this road for non -industrial activity as soon as construction is
completed. A completed EPA Form 3510-2F, Application for Permit to Discharge Storm
Water Discharges Associated with Industrial Activity, is enclosed. As stated in the
cover letter for the NPDES permit renewal application (EPA Form 3510-1) submitted
April 3, 2000, CP&L would like the reissued NPDES permit to reflect these storm water
discharges.

Item III - Site Drainage Map
The enclosed site drainage map is for the section of roadway from which storm water
will discharge to Lake Julian. Storm water from other sections of the road will flow to
either the ash pond or to the hot pond prior to discharging to, respectfully, the French
Broad River and Lake Julian. These discharges to Lake Julian and the French Broad
River are NPDES permitted discharge outfalls. The portion of the road from which
storm water will discharge directly to Lake Julian is divided-into-3-separate drainage
areas each with an outfall. Storm water that is routed to SW-1 is carried to Lake Julian
using piping, grass -lined ditches, concrete -lined ditches and sheet flow. The area
drained contains CP&L property, non-CP&L property, the access road and a railroad
storage yard where coal filled rail cars can be stored. Storm water that is routed to SW-
2 will be collected in a riprap-lined ditch that will then allow sheet flow to Lake Julian.
The area drained contains only the access road. Storm water that is routed to outfall
SW-3 will be routed through piping and both grass and riprap-lined ditches. The area
drained for SW-3 includes CP&L property, non-CP&L property, the access road, and
the railroad storage yard. CP&L can only provide a rough estimate of impervious area
for the property not owned by CP&L.
The property used for this road was recently purchased by CP&L. The past use of this
property was residential; therefore, CP&L has no knowledge of any significant materials
that have been treated, stored or disposed on this property in the past. CP&L staff
performed a limited Phase 1 Environmental Site Assessment on this property and found
no visual evidence of the storage, use, or disposal of chemicals or hazardous
substances. Any chemicals used are likely limited to consumer products in limited
quantities. CP&L has stored in the past and will store in the future coal at the railroad
storage yard. The coal is contained in rail cars that are waiting to be unloaded at the
plant. Other than the coal stored at the railroad storage yard, CP&L has not treated,
stored or disposed of any significant materials on any property already owned by CP&L
in the drainage area of this access road and has no plans to treat, store, or dispose of
significant materials on this access road or on immediately surrounding property owned
by CP&L in the future. No materials loading or unloading activities will take place on
the access road, railroad storage yard, or on immediately surrounding property owned
by CP&L. Various brands of commercial herbicides (i.e., Roundup, Crossbow) might be
used to control weeds and other unwanted plant.growth for security reasons. These
herbicides will be carefully applied by licensed applicators, or persons under the
immediate supervision of a licensed applicator, in accordance with the manufacturer's
instructions. After the road construction is completed and ground cover has been
established, fertilizers are not expected to be applied by CP&L. No pesticides or soil
conditioners will be used by CP&L. No hazardous waste treatment, storage, or disposal
will occur on this property.

Item IV C
No conventional treatment will be provided for the storm water drained from Outfalls
SW-1, SW-2 and SW-3. Prior to discharging to Lake Julian, storm water from Outfalls
SW-1 and SW-2 will flow over a vegetative buffer which will provide some filtering of
sediment from the storm water.
All coal trucks that travel on the access road are required to be covered -which will
reduce the spillage of coal on this road. These same trucks are requested to wash
down their wheels prior to exiting the site. The wash water from these wheel washes is
discharged in the ash pond for treatment.
During maintenance activities, sludges removed from ditches or manholes may be
transported to the old and/or new ash pond for disposal.

Item VII
Since the access road has not been constructed yet, the data in the tables are
estimates for the Asheville Plant. This data was reported for storm water Outfall 005 at
the Mayo Steam Electric Plant (NPDES permit NC0038377). The storm event that
produced this data is documented in Part D. The flow for this rain event was measured
using an open channel flow equation. Total Arsenic and Total Selenium data were
taken from a sample collected from an once -through cooling water discharge (Outfall
001) at the Asheville Plant. Total -Residual Chlorine and Free Available Chlorine are not
expected to be present in the discharge and are estimated to be below the detection
limit. Temperature of the storm water discharges is not estimated and is not expected
to negatively contribute to Lake Julian. The three storm water outfalls will have
substantially identical effluents, therefore, only one set of tables has been completed.
