Central Office Review Summary:
1. Owner's Other Permits:
o N00065099 Prim Enrg of NC LLC Southport- Outfall 001 includes flow, oil & grease and TSS. Outfall
002 includes chlorine, chromium, flow, and zinc. Outfall 003 includes an annual pollutant scan. Outfall
004 includes conductivity, DO, flow, nitrogen, pH, TSS and temperature.
2. General Observations: The site has six different outfalls.
3. Impairment: Price Creek is not on the 303(d). The Basinwide Plan for Cape Fear 2005 did not mention Price
Creek.
4. Threatened and Endangered: There are many federally and state protected species within 2 miles of the
facility based on Natural Heritage Virtual Workroom. Listed are federally protected aquatic species.
o Acipenser brevirostrum (Sortnose Sturgeon) Federal E (Brackish water of large rivers and estuaries;
spawns in freshwater areas )
o Chelonia mydas (Green Seaturtle) Federal T (Nests on beaches; forages in ocean and sounds)
o Trlchechus manatus (West Indian Manatee) Federal E (Warm waters of estuaries and river mouths)
5. Location: SC; Sw
6. Industrial Changes Since Previous Permit: In 2006, the facility added unadulterated wood as an alternative
fuel.
The wood is stored in a dedicated storage bin which directs rain runoff to the waste treatment basin via a vee
ditch. Transfer of the wood chips to the fuel blending area occurs within the coal yard storage area which is
drained to the plant WWTP preventing any stormwater contamination from the transfer process.
Email correspondence from James Moore ([e-mail]) on 04/07/08 indicates future changes for
the Southport and Roxboro facilities. They asked for a response on what do based on their stormwater and
waste water permits.
The changes are to be completed in early 2009. Both plants are power generation facilities that burn coal,
tire -derived fuel (TDF) and unadulterated wood to produce steam and electrical power. The electricity
generated is sold to the Grid, the steam at the Southport facility is also sold to a host.
Summary of future changes:
u Inslallabori of a SNCR (sele(Aive nuri-c.alalylic, reducliun) arnrnonla Injection for NOx Reduction.
The SNCR system will include 1 or 2 NH3 storage tanks to supply NH3 to the SNCR in the boiler off -gas
ducts. The injected NH3 will be consumed in the process. Design will provide isolation from the
wastewater systems and stormwater contact.
o Installation of Fuel Processing Equipment —grinders and additional conveyors.
The grinder will handle off -spec wood. The additional conveyors will transport additional alternative fuels
(tire derived fuel and wood). Design will be to contain fuel fines in the fuel yard. Design will contain yard
run-off and direct it through the wastewater treatment system.
Summary of Impact Assessment on the future changes:
The SNCR ammonia system will be designed to isolate the NH3 from any release that could be exposed to
rainwater resulting in contaminated run-off.
The S02 adsorbent system will be designed as a closed system to prevent any release that could be exposed to
rainwater resulting in contaminated run-off.

All fuel storage areas (fuel yard) will have perimeter drainage ditches to transport run-off to the wastewater
system for treatment (solids settling and removal) prior to discharge via the NPDES permitted outfalls.
The fuel processing equipment will be designed and operated within the fuel yard to control fugitive solids to
prevent entrainment in rainwater resulting in transport of fuel solids off -site.
DENR's Response by Ken Pickle on April 9, 2008.
Each site is already has a Stormwater Pollution Prevention Plan. They need to update is with changes to
the site.
While the expired permit is in review, abide by the provisions of the old permit.
As the new site activities and materials add arnrnonia, sudiurn carbonate, and a grinder, we cannot offer a
comment on how these may affect the renewal of your permit. The reviewer will address changes to the
renewal permit.
Kens Pickle's notes: New materials on site appear to be: ammonia for NOx absorbtion (possibly in the form of
aqueous arnrnunia, a 29% supersaturated pressurized liquid; or in the form of just the gas NH3 in pressurized
tanks) and could result in a HNO3 by product or conversion of the gaseous NOx into a deposited solid that
might be transported to the innocuous material, although whether there is a resulting H2SO4 product from the
reaction is beyond my knowledge. Addition of a grinder makes me wonder if there will be piles of wood chips
or sawdust that might argue for TSS or COD monitoring to detect wood waste leachate.
7. Analytical Monitoring Notes:
o There were 7 samples submitted from 12/5/02 to 4/17/06 for TSS and COD. None of values is over the
current benchmarks.
o See Table 1 below.
o The EPA Sector -Specific Permit, 2008, "Sector 0 — Steam Electric Generating Facilities" recommends
monitoring for Fe, TSS and pH.
Benchmarks were adjusted because of the receiving stream is classified as a SC Stream (salt water).

8. Qualitative Monitoring Notes:
o The visual monitoring was done 8 times from 5/20/02 to 10/4/05 on outfall 001. The monitoring
shows no signs of pollution but is all the same. It only asks if each parameter is acceptable and every
answer is yes.

Revised Permit Recommendations: Analytical Monitoring:
1. Maintaining parameters...
a. TSS — to track solids concentration. Sandy soils and equipment/truck traffic potential source;
b. COD — submitted analytical results show moderate oxygen demand in stormwater.
2. Adding parameters... the following parameters were added as part of a comprehensive effort to investigate
stormwater pollution associated with coal-fired power plant facilities:
a. 13 priority pollutant metals (Ag, As, Be, Cd, Cr, Cu, Hg, Ni, Pb, Sb, Se, TI, Zn) plus Al and B — basis:
known association with coal and coal combustion. Draft RTI Study ('Human and Ecological Risk
Assessment of Coal Comhustion Wastes', RTI, August ?007) and discussions with Robert Schreusdalo
of RTI suggest these metals may signal contamination problems. Have also discussed contaminants
with Dr. Avner Vengosh from Duke University, who researched ash pond spills in TN last year. In
addition, RRO/DWQ has sampled discharges from cogeneration plants in the FRO area and flagged
several of these metals of concern. Finally, DWQ has little data with which to characterize stormwater
discharges from this industry but knows there is concern;
b. Sulfate — conventional pollutant associated coal;
c. 0&G — conventional pollutant associated with onsite petroleum storage and truck traffic.
3. pH added — standard addition to permit.
4. All analytical monitoring set to semi-annually. Cover letter to permittee will include language to allow the
perrnillee to cunl.acl DWQ and request modifications of the required monitoring parameters and/or frequency
if justified by sufficient data collection.
5. Benchmarks for analytical monitoring and Tiered monitoring system added to this draft permit.
6. Analytical and qualitative monitoring required during representative storm events. Qualitative monitoring
required regardless of representative outfall status.
7. Flow reporting replaced by total rainfall parameter.
8. Vehicle maintenance monitoring revised to semi-annually.
Other Proposed Changes to the Previous Permit:
1. See draft permit for full details.
Discussions with permittee: Gary Hickey, 910-457-5056
Jim Moore answered the questions by email:
1. Have there been any changes since filing the application?
Operational Change:
- Adjusted fuel ratios — more unadulterated wood, more tire -derived fuel (TDF), less coal
Note some fuels as prior operation —just different feed ratios
Physical Changes Affecting Stormwater:
- 2006 — addition of Reverse Osmosis (RO) Sys tern — RO reject water directed to Wastewater Basins ( HO
attachment )
- 2009 — Addition Fuel Pud fur storage — stormwater directed to Wastewater Basins — planned completion
by 1212009

- 2009 — New internal plant roadway — stormwater directed to Sand Filter BMP to existing Outfall #001 —
planned completion by 1212009
- Note - Outfall #3 does not connect with Outfall #1 until the NPDES outfall, therefore stormwater from the
Project sand filter BMP will not be tested under the current testing procedure. This change will need to be
added to the new Stormwater Permit
- 2009 New loydown yard and contractor area — stormwater directed to Wet Detention Basin BMP to
Outfall #XXX — planned completion by XX/XXXX
- 2009 — New Buildings - small footprint, i.e., less than 2000 ft.2
2. Why are all the qualitative monitoring results the same?
I have attached the 2006 Application submitted in October of 2006. The qualitative results reflect "Y"
indicating acceptable conditions at all sampled outfalls
3. The site map shows six different sw outfalls. Why were all of these not sampled?
The Southport site has five (5) different drainage areas —with three SW Outfalls #1, #3, and #4
Drainage Area #1 — Power Plant bldg & surrounding area — drains to the Wastewater Treatment Plant (WWTP)
and to SW Outfall #1
Drainage Area #2 — Coal Storage Area — drains to the WWTP — no SW outfall
Drainage Area #3 — Southeast perimeter — most of area sheet flows to the perimeter ditch — NE end discharges
to Outfall #3
Drainage Area #4 — Cooling Tower Area — drains to Outfall #4
Drainage Area #5 — North and Fast side perimeter area — No SW outfall
No Sampling of Outfolls Nos. 3 and 4 - Based on site Topography ( mostly sheet flow from these areas to
perimen ter ditches), flow from Outfalls Nos. 3 and 4 was null and hence was not sampled. See 2008 Outfall
Spreadsheet
4. Do you have vehicle maintenance onsite? No
5. How many acres is the site?
The Southport site is approximately 29.2 ACRES
Note — Southport is planning the annexation of approx. 20 acres of Progress Energy to construct a roadway to
the north side of the plant. This parcel will have a separate E&SC Plan and SW permit application submitted
separately.

Talked with Linda Willis about the site 04/02/09
Site changed names to Epcor and should have sent in a name change form.
-Stores wood chips and will burn wood chips and rubber
-Linda recommends monitoring about all six outfalls. They can apply for representative outfall status after data
has been collected. Maybe include ammonia if woodchip area is covered but it should go to their wastewater
treatment settling basins.

PERMITTED DISCHARGES
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan 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 water(s) to which the
stormwater outfall(s) discharges, or if the discharge is to a municipal separate
storm sewer system, the name of the municipality and the ultimate receiving
waters, and accurate latitude and longitude of the point(s) of discharge. The
general location map (or alternatively the site map) shall identify whether each
receiving water is impaired (on the state's 303(d) list of impaired waters) or is
located in a watershed for Which a 'TMDL has been established, and what the
parameter(s) of concern are.
North Carolina's 303(d) List can be found here:
http://h2o.e:nr.state'.ne.us/tmdl/General-303d.htm#Downloads
North Carolina TMDL documents can be found here:
httpe//h2o.enr.state.nc.us/trradUTMDL list.htm#Final 'TMDLs.
(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 which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: 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, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate
spill impacts.
Part II Page 1 of I 1

Permit No. NCS00348
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 3. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of opei ations acid/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. 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, the stormwater management plan shall document the feasibility of
diverting the stornwater runoff away from areas of potential contamination.
(b) Secondary Containment Re1.quirements and Records. Secondary containment is
required for: bulk storage of liquid 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 directly 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), and any stormwater that accumulates
in the containment area shall be at a minimum visually observed for color, foatit,
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 the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater, and the date and time of the release shall be kept for a
period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) 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 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 RMPs. The BMP Summary shall be reviewed and updated annually.
Part II Page 2 of 11

Permit No. NCS00348
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) 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 the potential to
contaminate stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stonnwater 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. The program shall list
all stormwater control systems, 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.
Inspection of material handling areas and regular cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housekeeping shall be recorded in writing and maintained
in the SPPP.
5. 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. Facility personnel (or team)
responsible for implomenting the training shall be identified, and their annual training
shall be documented by the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the Stormwater
Pollution Prevention Plan shall be reviewed and updated on an annual basis. The annual
update shall include an updated list of significant spills or leaks of pollutants for the
previous three years, or the notation that no spills have occurred. The annual update shall
include re -certification that the stoi nwater outfalls have been evaluated for the presence
of non-stormwater discharges. Each annual update shall include a re-evaluation of the
Part II Page 3 of 11

Permit No. NCS00348
effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management
Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
8. Facility Inspections. Inspections of the facility 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 sop tatitig itispectiou
dates (unless performed more frequently than semi-annually). These facility inspections

SECTION B: ANALYTICAL. MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The
time between this storm event and the previous storm event measuring greater than 0.1 inches must be at
least 72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For
example, if it rains but stops before producing any collectable discharge, a sample may be collected if the
next rain producing a discharge begins within 10 hours.
