Outfall 001
As of October 2016, the 1982 ash basin has been fully excavated of ash. This area will now become the
construction site for the future Natural Gas Combined Cycle station that is scheduled for completion at the
end of 2019. Upon completion of the Natural Gas fired combined cycle generation station, the coal fired
facility will be retired. All ash wastes are expected to be removed completely from the 1964 ash basin by
applicable regulatory deadlines. The Plant's remaining ash basin (hereinafter referred to as the 1964 ash
basin), is located east of the French Broad River, south of the plant and discharges into the French Broad
River. With the approval of the North Carolina Department of Environmental Quality (NC DEQ). Duke
relocated treated waters from the 1982 ash basin and lined rim ditch to a slightly downstream outfall
location on the French Broad River. This relocation was necessary to allow for enhancement to the dam of
the 1964 ash basin to bring it up to current engineering standards.
Additionally, Duke engineered and constructed a temporary lined rim ditch as approved by the North
Carolina Division of Water Resources (March 2014), to process wastewater generated while the remaining
ash in the 1982 ash basin was being excavated. The lined rim ditch is located within the footprint of the
1964 ash basin. To accommodate closure of the 1982 ash basin, several approved changes to wastewater
systems and routing have occurred since the July 2014 update.
The flue gas desulfurization (FGD) waste stream and wetland wastewater treatment system were removed
service in October 2015. Notice of this change was provided to DEQ in a letter dated July 22, 2015. The
wetland wastewater treatment system materials were excavated, characterized and disposed of in an
approved landfill. Currently, the FGD waste stream is pretreated onsite and then discharged from the
wastewater treatment building to the Metropolitan Sewerage District of Buncombe County as authorized by
industrial user permit # S-074-15. The FGD waste stream description will remain in this application
pending engineering research that may allow an ultra -filtration (UF) treatment system to allow FGD flows to
be combined back into Outfall 001. This OF system will have clean -in -place chemicals consisting of an acid
and caustic cleaning. There may be the need for an additional coagulant chemical before the OF to prevent
plugging. These exact chemicals will be defined with the selection of the technology at a later date.

Also to accommodate 1982 ash basin closure, low volume waste and stormwater flows have been re-
routed to enter the 1964 ash basin's remaining open water area. The final polishing treatment previously
provided by the 1964 ash basin's remaining treatment volume was replaced by a filter system. The 1964
ash basin open water area will now also act as the collection point for wastewater flows associated with
ash excavation of the 1964 ash basin and will discharge to the rim ditch system for treatment through a
floating suction intake and pump systems.
The ash basin and/or rim ditch 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, reverse osmosis system reject water, storm water, collected basin
seepage 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 rim ditch.
The ash basin and/or rim ditch provides treatment by sedimentation and neutralization to the above -
referenced individual waste streams. Water leaves the rim ditch via weirs and curtains to the lined center
pond where a skimmer pulls water into 1 of 4 filter trains and flows by pipe via either the 1964 ash pond or
direct discharge by pipe to a lined stilling pond, where the discharge is treated by an automated pH system,
where it is then discharged by overflow to a pipe that coveys it to the French Broad River. Toe drains from
the former 1982 basin drain to the French Broad River. Toe drains from the 1964 basin are currently
collected and pumped to the rim ditch and flow through the treatment system to outfall 001 and the French
Broad River. Upon permit issuance, toe drains flows may be released to the French Broad River. Detailed
descriptions of the individual waste streams are below. Additionally, a detailed map with the location of
various seeps on the property is being provided as part of this permit application.
Ash Sluice Water
Fly ash and bottom ash from both units are hydraulically conveyed by an ash sluice pipeline to the ash
pond and/or lined rim ditch. As needed, alum and/or other chemical flocculants and coagulants may be
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 1964 ash basin and/or lined rim
ditch via ash sluice water. As necessary, a system to mitigate S03 emissions may also inject additional

Supplemental Information Package
ammonia into the combustion process. This mitigation system has not been needed to date but may
become necessary as fuel sources change. Various wastewater boiler sediments and ash accumulations
from wastewater processes collected during maintenance activities may also be physically transported to
the 1964 ash basin and/or lined rim ditch. The ash basin and/or lined rim ditch discharge into the
secondary settling pond prior to discharging to the French Broad River. With the approval of the North
Carolina Division of Water Quality, Duke Energy Progress, Inc. relocated this secondary settling pond and
discharge point 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 1964 ash basin or lined rim ditch for treatment. During maintenance
activities, wastewater sludges removed from catch basins, sumps, etc. may be transported to either the
lined rim ditch or the 1964 ash basin for treatment and further handling.
Limestone and Gypsum Piles Runoff
Storm water runoff from the limestone and gypsum piles is collected in drainage ditches which are routed to
the lined rim ditch for treatment. During maintenance activities, sludge removed from catch basins, sumps,
etc. may be transported to the 1964 ash basin, and/or lined rim ditch for treatment and further handling.
Stormwater
Storm water runoff from the plant area, parking lots, combustion turbine area, oil storage and handling
facility and the plant's substations is routed to the ash ponds and/or lined rim ditch for treatment. During
maintenance activities, sludge removed from catch basins, sumps, etc. may be transported to the 1964 ash
basin, and/or lined rim ditch for treatment and further handling.
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 blowdown and drainage is
sent to the ash basin and/or lined rim ditch and may contain small quantities of the chemicals. A Reverse
Osmosis system or alum coagulation/filtration service is used in conjunction with the vendor supplied

equipment to provide water for various plant processes. The reject stream from the Reverse osmosis unit
is sent to the 1964 ash basin and/or lined rim ditch. Some molybdate waste from the closed cooling water
system is created through valve leakage and maintenance activities and is discharged to the 1964 ash
basin and/or lined rim ditch. 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 1964 ash basin and/or lined rim ditch. A sodium hydroxide solution is fed into
this flow stream as necessary for ash basin /rim ditch pH adjustment. Sulfuric acid is fed to the ash sluice
water as necessary for 1964 ash basin and/or rim ditch pH adjustment to comply with NPDES permit
requirements. 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 1964 ash basin and/or lined rim ditch via plant drains or coal pile runoff. Small amounts
of urea waste from bulk urea unloading operations are discharged to the 1964 ash basin and/or lined rim
ditch. All plant area floor drains are routed to the 1964 ash basin and/or lined rim ditch and include
equipment drainage and wash down along with rainfall runoff. During maintenance activities sludge
removed from catch basins, sumps, etc. may be transported to the 1964 ash basin, and/or the lined rim
ditch for treatment and further handling.
In many cases, added chemicals are consumed or chemically altered during the plant processes. Only
trace amounts might be recoverable in water entering the 1964 ash basin and/or lined rim ditch. Detectable
levels of these chemicals would not be expected to occur in ash basin or rim ditch discharges.
Flue Gas Desulfurization Blowdown (Low Volume Waste)
This system is currently discharging to the Metropolitan Sewerage District (MSD) from waste water
treatment building, 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 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. Chemicals are used to adjust pH and to aid solids removal in the clarifier. The waste
stream enters a weir box and is discharged into a connection to MSD.

Air Preheater Cleaning (Low Volume Waste)
The air preheater will be water washed approximately once per year or more frequently as needed. The
wastewater from this activity will be discharged to the 1964 ash basin or lined rim ditch.
Chemical Metal C/eanina 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 basin, and/or lined rim ditch, 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 Low volume 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 1964 ash
basin and/or lined rim ditch. During maintenance activities, sludge removed from catch basins, sumps, etc.
may be transported to the 1964 ash basin, and/or the lined rim ditch for treatment and further handling.
Duke anticipates the 1982 ash basin will be decommissioned in April 2017. At that time Duke will
provide notification to the agency for removal of the 1982 ash basin as a treatment system from the
NPDES Permit #NC0000396.
Internal Outfall 005
Duke initially discussed treatment of the FGD system in a letter to NC DWQ dated February 25, 2015, this
change in the treatment system was necessary to facilitate the decommissioning of the 1964 ash basin.
In a letter dated July 22, 2015, Duke provided notice that the wetlands wastewater treatment system was
being removed from service when the FGD system was connected to the Metropolitan Sewage District
(MSD). Based on requirements found in the recently updated Federal Stream Electric Effluent Guidelines,
Page 6 of 10

Duke Energy Progress, LLC.
Asheville Steam Electric Plant
NPDES PERMIT # NC0000396
Supplemental Information Package
Duke will need to disconnect from the MSD on or before November 1, 2018. Once disconnected from the
MSD, Duke would need to add an alternate treatment for the FGD wastewater in lieu of the wetlands until
the Plant ceases operations in 2019. Internal outfall 005 was decommissioned when the wetlands were
removed from process flows. For these reasons, Duke requests for the designation of internal
outfall 005 and the FGD waste stream description to remain in the permit but to remove the
sampling requirements until waste from FGD operations is once again directed to the French Broad
River.
Steam Electric Effluent Guidelines
Duke requests an alternate applicability date for the Steam Electric ELGs in accordance with the request
found in Attachment E. The Asheville Steam Station currently consists of a two unit coal-fired generating
station with a capacity totaling 384 MW1378 MW (winter/summer). Treated bottom ash transport water
(BATW) and treated fly ash transport water (FATW) are currently discharged from the station. FGD
wastewater is currently permitted to discharge through internal outfall 005 and ultimately discharged
through outfall 001. As discussed in the above paragraph, the wetlands have been removed and the FGD
wastewater is temporarily being routed to the sanitary sewerage district for final treatment and discharge,
The ELG Rule sets a range of possible applicability dates for compliance with the new best available
technology (BAT) limits for bottom ash transport water (zero discharge) and FGD wastewater (numeric
limits for selenium, arsenic, mercury, and nitratelnitrite), as well for fly ash transport water (zero discharge),
The regulation provides that all permits issued after the effective date of the rule (January 4, 2016) should
contain applicability dates for compliance with the BAT limits, and that those dates should be "as soon as
possible" but not sooner than November 1, 2018 and not later than December 31, 2023. Per the Mountain
Energy Act of 2015, both coal-fired steam stations are scheduled to retire by January 31, 2020. The
generation will be replaced with a new combined -cycle station expected to be operational in late 2019. Due
to the retirement dates for these units, Duke Energy is requesting an ELG applicability date of January 31,
2020 for BATW, FATW and FGD wastewater.

CWA Section 316(b)
With the pending retirement of the Asheville Steam Station, Duke is contending the 316(b) Rule for Existing
Facilities is not applicable to the coal-fired station. Per 40 C.F.R. §122.21 (r)(1)(ii)(F), if the owner of an
existing facility plans to retire the facility before the current NPDES permit expires, then the 316(b)
submittal requirements listed in §122.21 (r)(1)(ii)(A), (B) and (C) do not apply. With the assumption the
renewed NPDES permit for Asheville Steam Station will expire after the scheduled retirement date, no
further action is required for the Asheville Steam Station to meet the 316(b) requirements for existing
facilities. The planned Asheville Combined -cycle station is expected to be classified as a new unit at an
existing facility per 40 C.F.R. §125.92(u). As required by 40 C.F.R. §125.95(b)(1), Duke will be submitting
information stated in 40 C.F.R. §122.21(r)(2) — (8) and (14) within 180 days before the planned
commencement of cooling water withdrawals for the operation of the new unit. A copy of the applicability
analysis can be found in Attachment E entitled Applicability of §316(b) of the Clean Water Act (CWA) to
the Asheville Steam Station.
Seeps Categorization and Disposition
Duke previously identified twenty-four (24) Areas of Wetness (AOWs) within the site property. A map of
AOW locations is provided in Attachment F. AOWs SD-01, N-01 and PO-1 are requested to be eliminated
from the NPDES permit since their analytical values indicate they are not influenced by CCR materials. It is
requested that AOWs B-01, E-01, F-02, and ponded water F be designated as effluent channels. A group
of AOWs 64-E01, 64E-02, 64E-03,C-02, C-03, C-05,and D-01 all discharge to AOW C-01, we request that
these AOWs are combined into a single effluent channel with the representative sampling location being at
C-01. Another group of AOWs 82E-01, 82E-02, K-01,K-02,F-03, and M-01 all discharge to AOW F01, we
request that this group of AOWs are combined into a single effluent channel with the representative
sampling location being at F-01. Duke requests that AOWs A-01 and A-02 be combined into a single
effluent channel with A-01 being designated as the sampling point. Duke requests removal of the
collection system located at the toe of the 64 ash basin, as these areas would be covered in the
effluent channel designations described above. Duke requests that DEQ provide concurrence or
acknowledgement of this request in the NPDES Fact Sheet for the permit.

Industrial Stormwater Outfalls
DEQ Division of Energy, Mineral, and Land Resources issued the Industrial Stormwater Permit
(NCS000575) May 24, 2016. The permit became effective on the date of issuance. Outfalls SW001,
SW002, and SWO03 are covered in the aforementioned permit. There are provisions in the permit for two
new outfalls upon completion of an new access road. The stormwater outfalls identified as SW004,
SW005, and SWO06 are not associated with industrial activities, therefore were not included in the
Industrial Stormwater Permit. Duke requests that outfalls SW004, SW005, SWO06 and the qualitative
monitoring requirements be removed from the NPDES permit.
Extraction Wells
A Settlement Agreement between the North Carolina Department of Environmental Quality (NCDEQ) and
Duke Energy signed on September 29, 2015 provided an additional requirement to implement accelerated
remediation at sites that demonstrated off -site groundwater impacts. Based on data collected for the
Comprehensive Site Assessment, potential off -site groundwater impacts were identified west of the 1964
ash basin, beneath a 12 acre parcel within the adjacent 1-26 right of way. An Interim Action Plan was
submitted in April 2016 that outlines the tasks to meet the accelerated remediation requirement. Initial
groundwater modeling has indicated removal of constituent mass from the area of highest constituent
concentrations will accelerate mitigation of groundwater impacts. Two extraction wells were installed in July
2016 (EXT-01 and EXT-02) and aquifer pumping tests were conducted during August and September
2016. Results of the pumping tests indicate one viable extraction well (EXT-01) has been installed with two
additional extraction wells recommended. Potential total discharge from a 3 well system extracting
groundwater from the transition zone and upper bedrock formation is estimated to range from 60 to 90
gallons per minute (86,000—130,000 gallons per day). The extracted groundwater will be treated prior to
discharge through outfall 001. Treatment of the discharge may be provided by a new treatment basin, new
direct groundwater treatment system or sent to the MSD as domestic waste.

Asheville Steam Station: Effluent Guidelines Rule
Justification for Applicability Dates
A. Introduction
Duke submits the following information as a justification for appropriate applicability dates for
compliance with the new Effluent Guidelines Rule (ELG Rule) (80 Fed. Reg. 67,838 (Nov. 3, 2015))
at Asheville Steam Station (Asheville), located in Asheville, North Carolina.
The Asheville Steam Station currently consists of a two unit coal-fired generating station with a
capacity totaling 384 MW/378 MW (winter/summer). Treated bottom ash transport water (BATW)
and treated fly ash transport water (FATW) are currently discharged from the station. FGD
wastewater is permitted to discharge through internal outfall 005 and ultimately discharged through
outfall 001.
The ELG Rule sets a range of possible applicability dates for compliance with the new best available
technology (BAT) limits for bottom ash transport water (zero discharge) and FGD wastewater
(numeric limits for selenium, arsenic, mercury, and nitrate/nitrite), as well for fly ash transport water
(zero discharge). The regulation provides that all permits issued after the effective date of the rule
(January 4, 2016) should contain applicability dates for compliance with the BAT limits, and that
those dates should be "as soon as possible" but not sooner than November 1, 2018 and not later than
December 31, 2023.
For Asheville, since the plant's final NPDES permit will be issued after January 4, 2016, but before
November 1, 2018, EPA specifically instructs permit writers to "apply limitations based on the
previously promulgated BPT limitations or the plant's other applicable permit limitations until at
least November 1, 2018." 80 Fed. Reg. at 67,883, col. 1 (emphasis added). As the rule makes clear,
however, BAT limits may apply — depending on the individual circumstances of the facilities subject
to the rule — any time within the window of November 1, 2018 to December 31, 2023. In selecting an
appropriate applicability date for each waste stream subject to the new BAT limits, the permitting
authority is called upon to determine an "as soon as passible" date.
The ELG Rule provides a very specific definition for "as soon as possible." The permit writer — when
supplied with appropriate information by the permittee — must consider a range of factors that affect
the timing of compliance. Those factors are as follows:
(1) Time to expeditiously plan (including to raise capital), design, procure, and install
equipment to comply with the requirements of this part.
(2) Changes being made or planned at the plant in response to:
(i) New source performance standards for greenhouse gases from new fossil fuel -
fired electric generating units, under sections 111, 301, 302, and 307(d)(1)(C) of the
Clean Air Act, as amended, 42 U.S.C. 7411, 7601, 7602, 7607(d)(1)(C);
(ii) Emission guidelines for greenhouse gases from existing fossil fuel -fired electric
generating units, under sections 111, 301, 302, and 307(d) of the Clean Air Act, as
amended, 42 U.S.C. 7411, 7601, 7602, 7607(d); or

(iii) Regulations that address the disposal of coal combustion residuals as solid waste,
under sections 1006(b), 1008(a), 2002(a), 3001, 4004, and 4005(a) of the Solid Waste
Disposal Act of 1970, as amended by the Resource Conservation and Recovery Act
of 1976, as amended by the Hazardous and Solid Waste Amendments of 1984, 42
U.S.C. 6906(b), 6907(a), 6912(a), 6944, and 6945(a).
(3) For FGD wastewater requirements only, an initial commissioning period for the
treatment system to optimize the installed equipment.
(4) Other factors as appropriate.
40 C.F.R. § 423.11(t).
Per the Mountain Energy Act of 2015, both coal-fired steam stations are scheduled to retire by
January 31, 2020. The generation will be replaced with a new combined -cycle station expected to be
operational in late 2019. Due to the retirement dates for these units, Duke Energy would like to
request an ELG applicability date of January 31, 2020 for BATW, FATW and FGD wastewater.
The steam electric industry is in the midst of major transitions driven by new environmental
regulatory requirements in the air, waste, and water arenas. In the ELG Rule, EPA explicitly
acknowledged the complications of planning and executing ELG retrofits while developing and
executing compliance strategies under other rules. EPA made it clear that the range of applicability
dates provided in the ELG Rule are supposed to be implemented in a manner that avoids stranded
costs and promotes orderly decision making. For instance, EPA states:
"From an environmental protection/coordination standpoint, with the increased use of
flue gas desulfurization scrubbers and flue gas mercury controls in response to air
pollution -related requirements, this rule makes sense from a holistic environmental
protection perspective and from the perspective of coordinating across rules affecting the
same sector. This final ELG controls the discharges associated with these particular
waste streams."
.. Response to Comments, p. 8-388.
The ELG Rule clearly allows consideration of stranded cost avoidance in setting the ELG
applicability date based on the need to account for any applicable obligations under the CPP.
However, in statements in the Response to Comments, EPA indicates stranded costs apply to any
rule, not just the CPP. EPA explains in the Response to Comments that it provided flexibility in
applicability dates so that facilities could consider all new regulatory requirements and then have an
adequate time to plan and implement accordingly, and thus avoid stranded costs:
"EPA is sensitive to the need to provide sufficient time for steam electric power plants to
understand, plan for, and implement any changes to their operation to meet their
environmental responsibilities, and agrees with the commenter that transparency of
requirements is important for minimizing "stranded investments." ...Furthermore, as
described in the preamble, the final rule provides time for plant owners or operators to
implement changes to plant operations in order to meet the final limitations and
standards, as well as flexibility to permitting authorities in implementing the final rule.
The Agency specifically considered the timing of requirements of other environmental
2

regulations in establishing implementation requirements for the ELGs, in order to provide
steam electric power plants time to consider and implement their strategy for
compliance."
Response to Comments, p. 8-388.
Furthermore, EPA also states that the permitting authority may "account for time the facility needs to
coordinate all the requirements of this rule, along with other regulatory requirements, to make the
correct planning and financing decisions, and to implement the new requirements in an orderly and
feasible way." Response to Comments, p. 8-129 (emphasis added).
In addition to stranded cost avoidance, EPA explicitly notes that the permitting authority should
consider grid reliability in setting applicability dates: "EPA's decision is also designed to allow,
more broadly, for the coordination of generating unit outages in.order to maintain grid reliability and
prevent any potential impacts on electricity availability, something that public commenters urged
EPA to consider." 80 Fed. Reg. at 67,854, col. 2. See also Response to Comments, p. 8-138. This
statement clearly applies to scheduling tie-ins with generating unit outages, but also implies the ELG
applicability date should consider grid reliability associated with unit retirements. In order to maintain
grid reliability in the area, the coal-fired units must remain operational until the new combined -cycle
is commercially available
To avoid stranded costs and maintain grid reliability, establishing an EGL applicability date of
January 31, 2020 is justified.

Applicability of §316(b) of the Clean Water Act (CWA) to the Asheville Steam Station
Final regulations to establish requirements for cooling water intake structures at existing facilities
were published in the Federal Register on August 15, 2014 (i.e. regulations implementing §316(b) of the
Clean Water Act) with an effective date of October 14, 2014. The Asheville Steam Station currently
consists of a two unit coal-fired generating station with a capacity totaling 384 MW/378 MW
(winter/summer). Per the Mountain Energy Act of 2015, both coal-fired steam stations are scheduled to
retire by January 31, 2020. The generation will be replaced with a new combined -cycle station expected
to be operational in late 2019. The following provides a discussion of the applicability of the 316(b)
regulations to the Asheville Steam Station and the new combined -cycle unit.
Asheville Steam Station
Per §125.91(a)(1)-(3) Applicability, the Asheville Steam Station is subject to the requirements at
§125.94 through §125.99 (316(b) requirements) based on the following:
— The facility is defined as an existing facility;
— The facility has a point source discharge;
— The facility uses a cooling water intake with a design intake flow (DIF) of greater than 2 million
gallons (MGD) to withdraw water from waters of the U.S.; and
Twenty-five percent or more of the water withdraws on an actual intake flow basis are
exclusively used for cooling purposes.
However, per §122.21 (r)(1)(ii)(F), if the owner of an existing facility plans to retire the facility before the
current NPDES permit expires, then the 316(b) submittal requirements listed in §122.21 (r)(1)(ii)(A), (B)
and (C) do not apply'. Therefore, with the assumption the renewed NPDES permit for Asheville Steam
Station will expire after the scheduled retirement date, no further action is required for the Asheville
Steam Station to meet the 316(b) requirements for existing facilities.
Asheville Combined -cycle Station
The planned Asheville Combined -cycle station is expected to be classified as a new unit at an
existing facility. The unit will be stand alone, will utilize the existing intake structure to obtain cooling
water, and the existing intake will not be modified to increase the design intake flow. Therefore,
§125.94(e) BTA standards for impingement mortality and entrainment for new units at existing facilities
is anticipated to be applicable to the planned Asheville Combined -cycle Station. As such, Duke Energy
plans to demonstrate compliance under §125.94(e)(1) by operating the cooling water system as a
closed -cycle recirculating system. Per §122.21 (r)(1)(ii)(D) New units at existing facilities, Duke Energy
will submit the following information:
1 §122.21 (r)(1J(ii)(A) requires all existing facilities to submit information listed in §122.21(r)(2) — (8).
§122.21 (r)(1)(h)(B) requires all existing facilities with an Actual Intake Flow (AIF) greater than 125 MGD to submit
information listed in §122.21 (r) (9), (10), (11), (12), and (13).
§122.21 (r)(1)(ii)(C) requires existing facility must also submit such additional information as the Director
determines is necessary.

§122.21(r)(2) Source Water Physical Data
— §122.21(r)(3) Cooling Water Intake Structure Data
— Applicable provisions of §122.21(r)(4) Source Water Baseline Biological Characterization Data
— §122.21(r)(5) Cooling Water System Data
— Applicable provisions of §122.21(r)(6) Chosen Method(s) of Compliance with Impingement
Mortality Standard
Applicable provisions of §122.21(r)(7) Entrainment Performance Studies
— §122.21(r)(8) Operational Status
— §122.21(r)(14) New Units
Furthermore, the actual intake flow (AIF) is expected to be well below 125 million gallons per day
(MGD). The additional information requested under §122.21(r)(9), (10), (11), (12) and (13), therefore,
are not applicable to the combined -cycle station. In accordance with §125.95(b) Permit application
submittal timeframe for new units, Duke Energy will submit information required in §122.21(r) within
180 days before the planned commencement of cooling water withdrawals for the operation of the new
unit.

Permit No. NCS000575
PART I INTRODUCTION
SECTION A: INDIVIDUAL PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration,
the permittee is authorized to discharge stormwater associated with industrial activity.
Such discharges shall be controlled, limited and monitored as specified in this permit.
If industrial materials and activities are not exposed to precipitation or runoff as described
in 40 CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES
stormwater discharge permit requirements. Any owner or operator wishing to obtain a No
Exposure Exclusion must submit a No Exposure Certification Notice of Intent (NO[) form to
the Division; must receive approval by the Division; must maintain no exposure conditions
unless authorized to discharge under a valid NPDES stormwater permit; and must recertify
the No Exposure Exclusion annually.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater to the surface waters of North Carolina or separate storm sewer system that
has been adequately treated and managed in accordance with the terms and conditions of
this permit. All stormwater discharges shall be in accordance with the conditions of this
permit.
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization, or
approval. The stormwater discharges allowed by this permit shall not cause or contribute
to violations of Water Quality Standards.
This permit does not relieve the permittee from responsibility for compliance with any
other applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or
decree.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan
(SPPP). The SPPP shall be maintained on site unless exempted from this requirement by
the Division. The SPPP is public information in accordance with Part III, Standard
Conditions, Section E, paragraph 3 of this permit. The SPPP should also specifically and
separately address deconstruction, demolition, coal, and/or coal ash hauling or disposal
activities. The SPPP shall include, at a minimum, the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility
and the potential pollutant sources that may be expected to contribute to
contamination of stormwater discharges. The Site Overview shall contain the following:
(a) 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 of the receiving waters to which the stormwater outfalls
discharge, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the points of stormwater discharge associated with industrial
activity. The general location map (or alternatively the site map) shall identify
whether any receiving waters are impaired (on the state's 303(d) list of impaired
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall. The
narrative should also reference deconstruction, demolition, coal, and/or coal ash
hauling or disposal activities where applicable.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls; all on -site and adjacent surface waters and
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas, loading and unloading areas, and haul roads); site topography and
finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious, and the site map
must include a graphic scale indication and north arrow.
Part II Page 1 of 13

(d) A list of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The permittee shall submit the first certification
no later than 90 days after the effective date of this permit to the Stormwater
Permitting Program Central Office and shall re -certify annually that the
stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. For any non-stormwater discharge identified, the permittee shall
indicate how that discharge is permitted or otherwise authorized. The certification
statement will be signed in accordance with the requirements found in Part III,
Standard Conditions, Section B, Paragraph 3.
2. Stormwater Management Strategy. The Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials, including
structural and nonstructural measures. This strategy should also address
deconstruction, demolition, coal, and/or coal ash hauling or disposal activities where
applicable. The Stormwater Management Strategy, at a minimum, shall incorporate the
following:
(a) Feasibility Study. A review of 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 rainfall and run-on flows. Wherever practical, the
permittee shall prevent exposure of all storage areas, material handling operations,
and manufacturing or fueling operations. In areas where elimination of exposure is
not practical, this review shall document the feasibility of diverting the stormwater
run-on away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of li uid materials; storage in any amount of Section 313
of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals; and storage in any amount of hazardous substances, in order to
prevent leaks and spills from contaminating stormwater runoff. A table or summary
of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems, the connection shall be controlled by manually
activated valves or other similar devices (which shall be secured closed with a
locking mechanism). Any stormwater that accumulates in the containment area
shall be observed for color, foam, outfall staining, visible sheens and dry weather
flow, prior to release of the accumulated stormwater. Accumulated stormwater
shall be released if found to be uncontaminated by any material. 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 (5) years. For facilities subject to a federal oil Spill Prevention,
Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan fully
compliant with the requirements of this permit may be used to demonstrate
compliance with this permit.
Part II Page 2 of 13

In addition to secondary containment for tankage, the permittee shall provide drip
pans or other similar protection measures for truck or rail car liquid loading and
unloading stations.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary should also address deconstruction,
demolition, coal, and/or coal ash hauling or disposal activities where applicable.
The permittee shall refer to the BMPs described in EPA's Multi -Sector Permit
(MSGP) and Industrial Stormwater Fact Sheet for Steam Electric Power Generating
Facilities (EPA-833-F-06-030) for guidance on BMPs that may be appropriate for
this site. The BMP Summary shall be reviewed and updated annually.
Spill Prevention and Response Procedures. The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based
on a materials inventory of the facility. Facility personnel responsible for implementing
the SPRP shall be identified in a written list incorporated into the SPRP and signed and
dated by each individual acknowledging their responsibilities for the plan. A
responsible person shall be on -site at all times during facility operations that have
increased potential to contaminate stormwater runoff through spills or exposure of
materials associated with the facility operations. The SPRP must be site stormwater
specific. Therefore, an oil Spill Prevention Control and Countermeasure plan (SPCC)
may be a component of the SPRP, but may not be sufficient to completely address the
stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may
be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed and implemented.
The program shall address all stormwater control systems (if applicable), stormwater
discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial
activity areas (including material storage areas, material handling areas, disposal areas,
process areas, loading and unloading areas, and haul roads), all drainage features and
structures, and existing structural BMPs.
The program shall establish schedules of inspections, maintenance, and housekeeping
activities of stormwater control systems, as well as facility equipment, facility areas,
and facility systems that present a potential for stormwater exposure or stormwater
pollution where not already addressed under another element of the SPPP. Inspection
of material handling areas and regular cleaning schedules of these areas shall be
incorporated into the program. Compliance with the established schedules for
inspections, maintenance, and housekeeping shall be recorded and maintained in the
SPPP. The program should also address deconstruction, demolition, coal, and/or coal
ash hauling or disposal activities where applicable. The Good Housekeeping Program
shall also include, but not be limited to, BMPs to accomplish the following:
PartII Page 3 of 13

(a) Minimize contamination of stormwater runoff from oil-bearing equipment in
switchyard areas;
(b) Minimize contamination of stormwater runoff from delivery vehicles and rail
cars arriving and departing the plant site;
(c) Inspect all residue -hauling vehicles for proper covering over the load,
adequate gate -sealing, and overall integrity of the container body. Repair
vehicles as necessary; and
(d) Reduce or control the tracking of ash and residue from ash loading and
storage areas;
5. Facility Inspections. Inspections of the facility (including tanks, pipes, and equipment)
and all stormwater systems shall occur as part of the Preventative Maintenance and
Good Housekeeping Program at a minimum on a semi-annual schedule, once during the
first half of the year (January to June), and once during the second half (July to
December), with at least 60 days separating inspection dates (unless performed more
frequently than semi-annually). These facility inspections are different from, and in
addition to, the stormwater discharge characteristic monitoring at the outfalls required
in Part II B, and C of this permit.
6. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill
response and cleanup, preventative maintenance activities, and for any of the facility's
operations that have the potential to contaminate stormwater runoff. The facility
personnel responsible for implementing the training shall be identified, and their
annual training shall be documented by the signature of each employee trained.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible
for the overall coordination, development, implementation, and revision of the SPPP.
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.
8. SPPP Amendment and Annual Update. The permittee shall amend the SPPP
whenever there is a change in design, construction, operation, site drainage,
maintenance, or configuration of the physical features which may have a significant
effect on the potential for the discharge of pollutants to surface waters. All aspects of
the SPPP shall be reviewed and updated on an annual basis. The annual update
shall include:
(a) an updated list of signiftcantspills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred (element of the Site
Overview);
(b) a written re -certification that the stormwater outfalls have been evaluated for
the presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater
BMPs (BMP Summary element of the Stormwater Management Strategy).
(d) a review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response
Part II Page 4 of 13

status. The permittee shall use the Division's Annual Summary Data
Monitoring Report (DMR) form, available from the Stormwater Permitting
Program's website (See'Monitoring Forms' here:
httj2://nortal.ncdenr.org./web/lrf npdes-stormwater).
If the Director notifies the permittee that the SPPP does not meet one or more of the
minimum requirements of the permit, the permittee shall have 30 days to respond.
Within 30 days of such notice, the permittee shall submit a time schedule to the
Director for modifying the SPPP to meet minimum requirements. The permittee shall
provide certification in writing (in accordance with Part III, Standard Conditions,
Section B, Paragraph 3) to the Director that the changes have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution
Prevention Plan and all appropriate BMPs consistent with the provisions of this permit,
in order to control contaminants entering surface waters via stormwater.
Implementation of the SPPP shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to
employees, including the log of the sampling data and of actions taken to implement
BMPs associated with the industrial activities, including vehicle maintenance activities.
Such documentation shall be kept on -site for a period of five (5) years and made
available to the Director or the Director's authorized representative immediately upon
request.
Part II Page 5 of 13

SECTION 13: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Tables
1-3. All analytical monitoring shall be performed during a measureable storm event at
the specified-stormwater discharge outfalls (SDOs) that discharge stormwater associated
with industrial activity (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a
shorter interval is representative for local storm events during the sampling period, and the
permittee obtains approval from the local DEMLR Regional Engineer. See Definitions
The following parameters shall be monitored during a measurable storm event from the
back entrance access road area, designated as Outfall SW001, SW002, SW003, SW-7, and
SW-8 discharging to an unnamed tributary to the French Broad River.

facility or until this permit is revoked or rescinded. If the facility is monitoring monthly because of Tier
Two or Three response actions under the previous permit, the facility shall continue a monthly monitoring
and reporting schedule in Tier Two or Tier Three status until relieved by the provisions of this permit or
the Division.
2 Grab samples shall be collected within the first 30 minutes of discharge. When physical separation between
outfalls prevents collecting all samples within the first 30 minutes, sampling shall begin within the first 30
minutes, and shall continue until completed.
Part II Page 6 of 13

J Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) specified above
unless representative outfall status (ROS) has been granted. The permittee may petition the Director for
ROS using DEMLR's ROS Request Form. DEMLR may grant ROS if stormwater discharges from a single
outfall are representative of discharges from multiple outfalls. Approved ROS will reduce the number of
outfalls where the analytical sampling requirements apply and will be documented in a letter to the
permittee. A copy of the Division's letter granting ROS shall be kept on site.
4 For each sampled measureable storm event, the total precipitation must be recorded. An on -site rain gauge
is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge reading
may be substituted for an on -site reading.
5 These parameters shall be monitored only if coal or coal ash is transported through the drainage areas of
these outfalls during the quarterly monitoring period in Table 3. Mercury shall be measured by EPA
Method 1631E.
The stormwater outfall identified as SW004, SW005, and SWO06 (outfalls along the main
entrance) is not associated with industrial activities. Any modifications to these outfalls
that result in a potential stormwater discharge associated with past or present industrial
activities will require a modification to this permit.
Should the permittee identify or create any new stormwater outfalls; remove any
stormwater outfalls identified in this permit; or alter any drainage areas that change
the potential pollutants in runoff discharged through corresponding outfalls, the permittee
will submit a request to NC DEMLR to modify this permit. For any newly discovered pipes
or outfalls, the permittee must evaluate the structure and provide a report of the status and
planned actions to NC DENR within 14 days. The permittee must either (1) request
modification of this permit and modify the SPPP accordingly, or (2) eliminate potential
discharges by removal, plugging, or combination of both.
The permittee shall complete the analytical samplings in accordance with the schedule
specified in Table 2, unless adverse weather conditions prevent sample collection (see
Adverse Weather in Definitions). Similarly, sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period 1 and Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
in the SPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period (see Part III, Section E). However, for purposes
of benchmark comparison and Tiered response actions, the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

Footnotes:
1 Maintain monitoring until either another permit is issued for this facility or until this permit is
revoked or rescinded. The permittee must submit an application for renewal of coverage before the
submittal deadline (180 days before expiration) to be considered for renewed coverage under the
permit. The permittee must continue analytical monitoring throughout the permit renewal process,
even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period.
Failure to monitor per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfall
during a monitoring period does not constitute failure to monitor, as long as it is properly
recorded and reported.
Proposed NPDES Wastewater Permit NC0000396 requires the facility to conduct fish
tissue monitoring once during that permit term for arsenic (As), selenium (Se), and
mercury (Hg) in accordance with a Sampling Plan approved by the Division of Water
Resources. The permittee shall submit annually a summary of the results of the fish tissue
monitoring results to the DEMLR Stormwater Permitting Program (Central Office) and
indicate the location of sampling in relation to stormwater discharge outfalls. This
reporting timeframe differs from the NPDES Wastewater Permit, which directs that fish
tissue analysis results be submitted with the wastewater discharge permit renewal
application.
The permittee shall compare monitoring results to the benchmark values in Table 3.
Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install stormwater Best Management
Practices (BMPs) in a tiered program. See below the descriptions of Tier One, Tier Two, and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three, the Division's
release letter may remain in effect through subsequent reissuance of this permit, unless the
release letter provides for other conditions or duration.

an assumed hardness of 25 mg/1 and a total suspended solids (TSS) concentration of 10 mg/l.
2 Values above the North Carolina water quality standard for mercury (12 ng/1) should be noted on the
DMR but do not trigger Tier responses. Concentrations infield blanks or method blanks associated
with the sample maybe subtracted from the results for that sample, as long as all documentation of the
adjustment is provided with the DMR.
3 If pH values outside this range are recorded in sampled stormwater discharges, but ambient
precipitation pH levels are lower, then the lower threshold of this benchmark range is the pH of the
precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain
gauge (or local precipitation data) must be documented to demonstrate background concentrations
were below the benchmark pH range of 6- 9.
The benchmark values in Table 3 are not permit limits but should be used as guidelines for
implementation of the permittee's SPPP. An exceedance of a stormwater benchmark value
is not a permit violation; however, failure to respond to the exceedance as outlined in this
permit is a violation of permit conditions.
Part II Page 9 of 13

Tier One
If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for
any parameter at any outfall;
Then: The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, and/or to bring
concentrations within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
S. Record each instance of a Tier One response in the SPPP. Include the date and value of the
benchmark exceedence, the inspection date, the personnel conducting the inspection, the selected
actions, and the date the selected actions were implemented.
6. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall
conduct monthly monitoring at every outfall where a sampling result exceeded the benchmark
value. Monthly (analytical and qualitative) monitoring shall continue until three consecutive
sample results are below the benchmark values or within benchmark range.
7. Note: Benchmark exceedances for a different parameter separately trie2er a tiered response.
Tier
If: The first valid sampling results from two consecutive monitoring periods are above the benchmark
values, or outside of the benchmark range, for any specific 2arameter at a specific discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Continue monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for twc,
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow' to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances,
exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier Three.
The Regional Engineer may direct the response actions on the part of the permittee as provided in
Tier Three, including reduced or additional sampling parameters or frequency.
S. If pursuing the alternative above after two consecutive exceedances, the permittee may propose an
alternative monitoring plan for approval by the Regional Engineer.
6. Maintain a record of the Tier Two response in the SPPP.
7. Continue Tier Two response obligations throughout the permit renewal_process.
Tier Three
If: The valid sampling results required for the permit monitoring periods exceed the benchmark
value, or are outside the benchmark range, for any specific parameter at any specific outfall on four
occasions, the permittee shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of
the fourth analytical results;
Then: The Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
Part II Page 10 of 13

• require the permittee to perform upstream and downstream monitoring to characterize impacts
on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
If a Total Maximum Daily Load (TMDL) is developed and approved for Lake Julian, or if this
body of water becomes impaired, the permittee may be required to monitor for the
pollutant(s) of concern in the future and submit results to the Division. The Division will
consider the monitoring results in determining whether additional BMPs are needed to
control the pollutant(s) of concern to the maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the Stormwater Pollution Prevention Plan.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP) and identify new potential sources of stormwater
pollution. Qualitative monitoring of stormwater outfalls must be performed during a
measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed quarterly as
specified in Table 4, and during required analytical monitoring events (unless the permittee
is required to perform further qualitative monitoring per the Qualitative Monitoring
Response, below). Inability to monitor because of adverse weather conditions must be
documented in the SPPP and recorded on the Qualitative Monitoring Report form (see
Adverse Weather in Definitions). Only SDOs discharging stormwater associated with
industrial activity must be monitored (See Definitions).
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee
shall document the suspected cause of the condition and any actions taken in response to
the discovery. This documentation will be maintained with the SPPP.

Footnotes:
1 Maintain quarterly monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must continue qualitative monitoring throughout the
permit renewal process, even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, the permittee must complete a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period.
Part II Page 12 of 13

Failure to monitor quarterly per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge" from an
outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded.
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are
ineffective, or that significant stormwater contamination is present, the permittee shall
investigate potential causes, evaluate the feasibility of corrective actions, and implement
those corrective actions within 30 days, per the Qualitative Monitoring Response, below.
A written record of the permittee's investigation, evaluation, and response actions shall be
kept in the Stormwater Pollution Prevention Plan.
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying new potential
sources of stormwater pollution, and prompting the permittee's response to pollution. If the
permittee repeatedly fails to respond effectively to correct problems identified by qualitative
monitoring, or if the discharge causes or contributes to a water quality standard violation, the
Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some
or all parameters (analytical or qualitative)
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.

Amended, and Regulation 40 CFR 136.
To meet the intent of the monitoring required by this permit, all test procedures must produce
minimum detection and reporting levels and all data generated must be reported down to the
minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below permit discharge
requirements, then the most sensitive (method with the lowest possible detection and reporting
level) approved method must be used.
5. Representative Outfall
If a facility has multiple discharge locations with substantially identical stormwater discharges that
are required to be sampled, the permittee may petition the Director for representative outfall status.
If it is established that the stormwater discharges are substantially identical and the permittee is
granted representative outfall status, then sampling requirements may be performed at a reduced
number of outfalls.
