This is the drain I mentioned this morning.As I mentioned the guys stopped immediately when
they realized the washdown water was going to the drain. The estimate would be 30-50 gallons.

Subject: Roxboro complaint
BIMS incident # 201300475:
Anonymous caller stated that one silo blew out at Capital Power Roxboro Plant in late February. The facility has been
hauling away solid fule material (wood residuals, tire -derived fuel, and coal), which was spilled on the road during
transportation. Caller is concerned about the potential impacts to surface and ground water when the material is
washed into the creeks by rain water.

Central Office Review Summary:
1. Owner's Other Permits:
• NC0065081 Prim Enrg of NC LLC Roxboro- includes limits for pollutant scan, cadmium, chlorine (free
available and total residual), chromium, copper, flow, lead, nickel, oil & grease, P/F Statre ceriodaphnia,
pH, TSS, temperature and zinc.
2. General Observations:
New site manager 03/20/2008: Terry McDaniel.
One Outfall to UT to Mitchell Creek
4 drainage areas: 3 stormwater, 2.7 acres, 3.7 acres, and 1.60 acres. 1 to waste basin, 2.2 acres.
Impairment: Mitchell Creek is not on the 303(d). The Basinwide Plan doesn't mention specifically Mitchell
Creek but the section cf Marlowe Creek [22-58-12-6b] downstream of Mitchell creek is Supporting aquatic life
due to Good -Fair fish and benthic community. This site showed water quality improvement from the 2001
basin plan. Cogentrix-Roxboro completed a Special Order of Consent for rectifying toxicity issues in 2003 and
have been in compliance. The segment [22-58-12-6b] remained on the 2008 303(d) list for zinc and copper
parameters. Recommendations included that Roxboro work towards implementing a stormwater program.
4. Threatened and Endangered: There are no federally or state protected species within 2 miles of the facility
based on Natural Heritage Virtual Workroom.
5. Location: C Stream
6. Industrial Chanties Since Previous Permit: in 2004, 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:
• Boiler modifications will involve addition of a Mobotech overfired air system upgrade and new fuel feed
hoppers.
• Fuel Handling system modifications will involve addition of a truck dumper, fuel conveyor and pad storage
systems.
• No new fuels or chemicals will be introduced as part of the project.
• Plant operations will remain the same regarding power generation.
• Installation of a SNCR (selective non -catalytic reduction) ammonia injection for NOx Reduction. This has
been cancelled as of 22/10/08 email.
The SNCR system would have included 1 or 2 NH3 storage tanks to supply NH3 to the SNCR in the boiler
off -gas ducts. The injected NH3 would have been consumed in the process. Design will provide isolation
from the wastewater systems and stormwater contact.
Page 4 of 9

NCS000347 •
Installation of Fuel Processing Equipment —grinders and additional conveyors. This has been cancelled as
of 12/10/08 email.
The grinder would have handled 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:
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 ammonia, sodium 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 ammonia, 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 H250a 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 10/28/02 to 4/8/06 for TSS and COD. None of values is over the
current benchmarks.
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.

Remised 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 Combustion Wastes', RTI, August 2007) and discussions with Robert Schreusdale
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
permittee to contact 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: Ruffin Shackelford, 336-597-4798
Jim Moore answered the questions by email:
1. General description of industrial activities?
2. Have there been any changes since filing the application?
Operational Change:
- Adjusted fuel ratios — more unadulterated wood, more tire -derived fuel (TOF), less coal
- !Vote same fuels as prior operation —just different feed ratios
Physical Changes Affecting Stormwater:
- 2009 - Annexation of 2-acre land parcel to southwest corner of plant site
- 2009 — Addition Fuel Pad for storage -- stormwater directed to Wastewater Basins — planned completion
by 1212009
- 2009 — New internal plant roadway
Page 7 of 9

NCS000347 0 0 ,
- 2009 —New Buildings -small footprint, i.e., less than 2000 ft.2
3. Why are all the qualitative monitoring results the same?
1 have attached the 2006 Application submitted in November of 2006. The qualitative results reflect "y"far
acceptable conditions.
4. The site map shows more than one outfall and 4 different drainage areas. Why were these not sampled?
The Roxboro site operates with one (1) SW outfalls No. 1 which discharges stormwoter off -site
The attached application shows only one SW outfall #1
Site drainage areas are sheet flow to an off -site drainage ditch which discharges via outfall #1
S. An aerial of the site shows storage in drainage 4 that isn't on the map. What is stored there?
6. The application says that water is sprayed onto the coal as it is unloaded. Where does this water go?
7. How many Acres is the site? The Roxboro site is approx 22 ACRES
8. Do you have vehicle maintenance onsite? What is your SIC code? No

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
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.
(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.
(c) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(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.
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:
Part It Page I of 6

0 Permit No. NCS000347
(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 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 stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, 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 narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as,'but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
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 team) responsible for implementing the
SPRP shall be identified. 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
stormwater specific. Therefore, a SPCC plan 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 program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.

Central Office Review Summary:
1. Owner's Other Permits:
• NC0065081 Prim Enrg of NC LLC Roxboro- includes limits for pollutant scan, cadmium, chlorine (free
available and total residual), chromium, copper, flow, lead, nickel, oil & grease, P/F Statre ceriodaphnia,
pH, TSS, temperature and zinc.
2. General Observations:
• New site manager 03/20/2008: Terry McDaniel.
• One Outfall to LIT to Mitchell Creek
• 4 drainage areas: 3 stormwater, 2.7 acres, 3.7 acres, and 1.60 acres. 1 to waste basin, 2.2 acres.
3. Impairment: Mitchell Creek is not on the 303(d). The Basinwide Plan doesn't mention specifically Mitchell
Creek but the section of Marlowe Creek [22-58-12-6b] downstream of Mitchell creek is Supporting aquatic life
due to Good -Fair fish and benthic community. This site showed water quality improvement from the 2001'
basin plan. Cogentrix-Roxboro completed a Special Order of Consent for rectifying toxicity issues in 2003 and
have been in compliance. The segment [22-58-12-6b] remained on the 2008 303(d) list for zinc and copper
parameters. Recommendations included that Roxboro work towards implementing a stormwater program.
4. Threatened and Endangered: There are no federally or state protected species within 2 miles of the facility
based on Natural Heritage Virtual Workroom.
5. Location: C Stream
6. Industrial Changes Since Previous _Permit: In 2004, 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:
• Boiler modifications will involve addition of a Mobotech overfired air system upgrade and new fuel feed
hoppers.
• Fuel Handling system modifications will involve addition of a truck dumper, fuel conveyor and pad storage
systems.
• No new fuels or chemicals will be introduced as part of the project.
• Plant operations will remain the same regarding power generation.
• Installation of a SNCR (selective non -catalytic reduction) ammonia injection for NOx Reduction. This has
been cancelled as of 12/10/08 email.
The SNCR system would have included 1 or 2 NH3 storage tanks to supply NH3 to the SNCR in the boiler
off -gas ducts. The injected NH3 would have been consumed in the process. Design will provide isolation
from the wastewater systems and stormwater contact.
Page 4 of 9

NCS000347
f�J
Installation of Fuel Processing Equipment — grinders and additional conveyors. This has been cancelled as
of 12/10/08 email.
The grinder would have handled 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:
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 ammonia, sodium 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 ammonia, 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 10/28/02 to 4/8/06 for TSS and COD. None of values is over the
current benchmarks.
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 Combustion Wastes', RTI, August 2007) and discussions with Robert Schreusdale
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
permittee to contact 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: Ruffin Shackelford, 336-597-4798
Jim Moore answered the questions by email:
1. General description of industrial activities?
2. 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:
- 2009 - Annexation of 2-acre land parcel to southwest corner of plant site
- 2009 — Addition Fuel Pod for storage — stormwater directed to Wastewater Basins — planned completion
by 1212009
- 2009 — New internal plant roadway
Page 7 of 9

NCS000347
- 2009 — New Buildings - small footprint, i.e., less than 2000 ft.2
3. Why are all the qualitative monitoring results the same?
I have attached the 2006 Application submitted in November of 2006. The qualitative results reflect "y"for
acceptable conditions.
4. The site reap shows more than one outfall and 4 different drainage areas. Why were these not sampled?
The Roxboro site operates with one (1) SW outfalls No. 1 which discharges stormwater off -site
The attached application shows only one SW outfall #1
Site drainage areas are sheet flow to an off -site drainage ditch which discharges via outfall #1
5. An aerial of the site shows storage in drainage 4 that isn't on the map. What is stored there?
6. The application says that water is sprayed onto the coal as it is unloaded. Where does this water go?
7. How many Acres is the site? The Roxboro site is approx 22 ACRES
8. Do you have vehicle maintenance onsite? What is your SIC code? No

Dear Mr. Gibbs:
Enclosed with this Ietter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters including 15 metals, sulfate, and oil & grease have been added to this
permit as an effort to investigate the pollution potential of stormwater discharges.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B. The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow"
within 30 days of the end of the six-month sampling period. Additionally, samples must be taken a
minimum of 60 days apart, as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. 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. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If during the term of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then the facility shall follow the
Tier 2 guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all parameters at.every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
5. You are required to collect all of the analytical and qualitative monitoring. samples during representative
storm events as defined in Part li Section B. Qualitative monitoring is required regardless of
representative outfall status.
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.

7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. Monitoring for TPH has replaced Oil & Grease. This requirement appears in
all Individual Stormwater permits, however it only applies to facilities that do vehicle maintenance. If the
facility begins vehicle maintenance during the permitted timeframe then the requirements shall apply.
Other permit changes:
I. Additional guidance is provided about the Site Plan requirements, The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part 11 Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part 11 Section A.
More details regarding secondary containment are provided.

• NCO065081 Prim Enrg of NC LLC Roxboro-. includes limits for pollutant scan, cadmium, chlorine (free
available and total residual), chromium, copper, flow, lead, nickel, oil & grease, P/F Statre ceriodaphnia,
pH, TSS, temperature and zinc.
2. General Observations:
• New site manager 03/20/2008: Terry McDaniel.
• One Outfall to UT to Mitchell Creek
• 4 drainage areas: 3 stormwater, 2.7 acres, 3.7 acres, and 1.60 acres. 1 to waste basin, 2.2 acres.
3. Impairment: Mitchell Creek is not on the 303(d). The Basinwide Plan doesn't mention specifically Mitchell
Creek but the section of Marlowe Creek [22-58-12-6b] downstream of Mitchell creek is Supporting aquatic life
due to Good -Fair fish and benthic community. This site showed water quality improvement from the 2001
basin plan. Cogentrix-Roxboro completed a Special Order of Consent for rectifying toxicity issues in 2003 and
have been in compliance. The segment [22-58-12-6b] remained on the 2008 303(d) list for zinc and copper
parameters. Recommendations included that Roxboro work towards implementing a stormwater program.
4. Threatened and Endangered: There are no federally or state protected species within 2 miles of the facility
based on Natural Heritage Virtual Workroom.
S. Location: C Stream
6. Industrial Changes Since Previous Permit: In 2004, 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 { moore o e corusa.com 4/07/08 in icates future changes for
the Southport and Roxboro facilities. They asked for a response o what do based n 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:
• Boiler modifications will involve addition of a Mobotech overfired air system upgrade and new fuel feed
hoppers.
• Fuel Handling system modifications will involve addition of a truck dumper, fuel conveyor and pad storage
systems.
• No new fuels or chemicals will be introduced as part of the project.
• Plant operations will remain the same regarding power generation.
• Installation of a SNCR (selective non -catalytic reduction) ammonia injection for NOx Reduction. This has
been cancelled as of 12/10/08 email.
The SNCR system would have included 1 or 2 NH3 storage tanks to supply NH3 to the SNCR in the boiler
off -gas ducts. The injected NH3 would have been consumed in the process. Design will provide isolation
from the wastewater systems and stormwater contact.
Page 4 of 9

NCS000347
• Installation of Fuel Processing Equipment —grinders and additional conveyors. This has been cancelled as
of 12/10/08 email.
The grinder would have handled off -spec wood. The additional conveyors will transport additional
alternative fuels (tire derived fuei'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:
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 ammonia, sodium 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 ammonia, 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 10/28/02 to 4/8/06 for TSS and COD. None of values is over the
current benchmarks.
8. Qualitative Monitoring Notes:
o The visual monitoring was done 8 times from 5/20/02 to 10/4/05 on outfali 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 Combustion Wastes', RTI, August 2007) and discussions with Robert Schreusdale
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. O&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
permittee to contact 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: Ruffin Shackelford, 336-597-4798
Jim Moore answered the questions by email:
1. General description of industrial activities?
2. 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 same fuels as prior operation — just different feed rotios
physical Changes Affecting Stormwater:
- 2009 - Annexation of 2-acre land parcel to southwest corner of plant site
- 2009 — Addition Fuel Pad for storage — stormwater directed to Wastewater Basins — planned completion
by 1212009
- 2009 — New intern at plant roadway
Page 7 of 9

NCS000347
- 2009 — New Buildings - small footprint, i.e., less than 2000 ft.2
3. Why are all the qualitative monitoring results the same?
1 have attached the 2006 Application submitted in November of 2006. The qualitative results reflect "y" for
acceptable conditions.
4. The site map shows more than one outfall and 4 different drainage areas. Why were these not sampled?
The Roxboro site operates with one (1 ) SW outfalls No. 1 which discharges stormwater off -site
The attached application shows only one SW outfall #1
Site drainage areas are sheet flow to an off -site drainage ditch which discharges via outfall #1
5. An aerial of the site shows storage in drainage 4 that isn't on the map. What is stored there?
6. The application says that water is sprayed onto the coal as it is unloaded. Where does this water go?
7. How many Acres is the site? The Roxboro site is approx 22 ACRES
8. Do you have vehicle maintenance onsite? What is your SIC code? No

I have not inspected this facility, mainly due to their being shutdown. They have not operated the plant much this
year, so from a wastewater prospective, I have been waiting on a discharge to run wastewater sampling. They
have some wastewater challenges with Zn and sometime Cu due to some process changes and the nature of start-
ups and shutdowns.
We last did an inspection (for wastewater and stormwater) on March 19, 2008 and the inspection is in Bims under
NCS000347, was found to be compliant, and Vicki Webb of the RRO was the inspector.
I suspect the same issues we found when sampling at FRO Coal Fired Co -generation plants are possible, so I would
check on stormwater language used in any recent renewals of other Coal Fired Co -generation plants, ie. 13 priority
pollutant (metals). I think the stormwater sampling we did in FRO is representative of these types of Co-
generation plants in general.
If you think we need to schedule a stormwater sampling event for this facility before issuance of the new
stormwater permit, let me know and I'll be glad to schedule a visit to the plant.
Thanks,

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 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,bc 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, yexisting structural BMPs. The
program shall establish schedules of.inspections, intenance, and housekeeping
activities of stormwater control systems,/as well as facility equipment, facility areas, and
facility systems that present -a potential for-starmwater exposure or stormwater pollution.
Inspection of material handlin�g,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 implementing 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 far 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 stormwater outfalls have been evaluated for the presence
of non-stormwater discharges. Each annual update shall include a re-evaluation of the

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 maybe collected if the
next rain producinga discharge begins within 10 hours.. A ,//

Measurement Frequency: Twice per year during a representative storm event, for each year until either another
permit is issued for this facility or until this permit is revoked or rescinded. If at the end of this permitting cycle
the permittee has submitted the appropriate paperwork for a renewal permit before the submittal deadline, the
permittee will be considered for a renewal application. The applicant must continue semi-annual monitoring until
the renewed permit is issued. See Table 2 for schedule of monitoring periods through the end of this permitting
cycle.
2 If the stormwater runoff is controlled by a stormwater detention pond, a grab sample of the discharge from the
pond shall be collected within the first 30 minutes of discharge.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative
outfall status has been granted.
4 Mercury shall be analyzed by EPA Low-level detection method 1631 E. This method also requires a field blank

Monitoring Strategy for Power Plant NPDES Stormwater
Permit Renewals in 2009
Renewal Permit Monitoring:
In recent years, the Stormwater Permitting Unit has recognized the complex issues
associated with coal -burning power plants and the increased attention on coal ash storage,
use;and disposal at these sites. Data on stormwater discharges from these plant sites is
limited because the focus has traditionally been on wastewater. Regions have also voiced
concern about potential contamination from metals in stormwater discharges associated
with the activities at these sites. After researching constituents these activities or materials
may introduce to the power plant property (and with them potential for stormwater
pollution), the Unit formulated a strategy for these renewal permits:
Basis: Draft RTI Study (`Human and Ecological Risk Assessment of Coal Combustion
Wastes, -RTI, August 2007) and discussions with Robert Schreusdale of RTI suggest
these metals may signal contamination problems. SPU also discussed contaminants
with Duke University researcher, Dr. Avner Vengosh, who researched the TVA ash pond
spill that occurred in Dec 2008 in Kingston, TN (Mtg with SPU on May 4, 2009). In
addition, RRO/DWQ has sampled discharges from cogeneration plants in the FRO area
and flagged metals of concern. Overall, we have very little data with which to
characterize stormwater discharges from this industry, but we know there is a concern
and need for better understanding about possible stormwater pollution from the
activities here.
(FYI - Cost of clean
mercury inethod-around $100.)
Basis: Power plants are a potential major source of mercury, and although some Hg
may be regional, there is a risk that significant quantities came from the activities at
the plant itself. While wastewater permit limits are calculated based on low stream
flow and -high wastewater effluent flow conditions —and sometimes do not warrant
the lower -detection method—stormwater contributions vary broadly and do not
change the bio-accumulative nature of methyl -mercury. SPU recognizes the
complexity ofregional air transport and deposition, as well as the cost and,resources
involved in clean mercury sampling protocol, and therefore will exempt Hgfrom
mon thly monitoring in the tier structure. However, ,if mercury data suggest a problem
driven by.sources or activities at the plant, DWQ should investigate further and could
require additional monitoring in the future.

asis: conventional pollutants associated with types of activities here. Note -include
provision to allow pH values below benchmark if facility can document rainfall pH is

Basis: Consistency with current draft General Permits and to facilitate prompter
awareness of monitoring results at the regional office level.
example, plants might consider installing bioretention cells for drainage areas
where metals are a problem and monitor for effectiveness, in exchange for
decreased monitoring frequency and/or no benchmark trigger. We will also
consider relieving monitoring if the facility can demonstrate levels are not
.-attributable-to,-or else not able to be separated from, industrial activities. SPU will
work'with the regional offices to address situations on a case -by -case basis.
Basis: SPU recognizes the ubiquitousness of copper and zinc, and the low benchmark
concentrations for metals like Cd, but we also know activities at power plants can be
contributors of these pollutants. SPUfeelsalternatives to more monitoring can
facilitate solutions and that the permit tier structure is flexible enough to relieve the
permittee of monitoring when appropriate.
Federal effluent guidelines apply specifically to the Steam Electric Generating
industry, which excludes cogeneration facilities. However, cogeneration plants are
similar in many respects, and coal storage and handling activities may even be
identical. SPU will consider a tailored approach for certain SDOs based on proximity
to coal sources, storage area size, etc. Depending on the size and similarity of the
coal storage and handling (and perhaps other factors), the permit writer could
decide to (a) apply limits initially, or (b) an arrangement where benchmarks
mirroring BPT requirements for coal pile leachate in 40 CFR §423 (TSS of 50 mg/l
and pH 6-9 SU) would become limits after two exceedences (i.e., Tier 2 action), or
(c) just impose benchmarks.
Basis: Federal storm water effluent limits apply to coal piles at steam electric
generating facilities; similarity of cogeneration plants (and -even elsewhere) warrant
-similar scrutiny. Other states such as Virginia, Ohio, and Georgia have already
imposed the some BPT limits on coal pile runoff and leachate at facilities where coal
burning forsteam electric generation is not necessarily the primary Industrial activity.
The flexibility for North Carolina to do the same follows that lead and acknowledges
the potential for the some pollution problems.

These samples went to lab the same time their freezer went out, so data is
qualified -not the best situation, but for identifying what's there, I think this
is relatively accurate.
Another sampling event would be needed, especially at Lumberton. Sampling should
probably be done at the Progress Energy Plant nearby that has the ash pond.

These two facilities have coal piles, but no ash ponds on site and neither
facility has been operating consistently. Neither was operating the day we
sampled. if operating expect these would be higher.
Just let me know if I can be of assistance.
Connie has so kindly pointed out that the metals sample results would not be
effected by the freezer/cooler issues experienced at lab, so my statement about
"results not being adequate.to determine compliance" is incorrect. Please review
the laboratory sections qualifiers by each analyte to determine. which analytes
were qualified. If you have not received a copy of the results from the lab, I
can scan and send the copies that .came to RRO.
Can you let me know if anyone is evaluating Lumberton Site "SW1 outfall" and "WW

may want to resample, since some levels in these results seem unusually high, but
that.'s up to FRO.
Sorry for the confusion.

Bethany,
Georgia's general industrial stormwater permit has TSS/pH limits for all coal
pile runoff, whether or not thethe source is a Steam Electric Generating Plant.
This has been the case since our first industrial stormwater permit issuance in
1993. We have not yet seen a good reason to modify our original permit language
and exclude facilities that are not Steam Electric Generating Plants from these
limits.

Our North Carolina Project has changed from the original design basis. This email is to provide you with an update to the
project scope per your request.
Our Schedule is to submit the Southport Costal Stormwater Permit to you by January 23`d 2009. It is our understanding
that your department has 60-days from determination of application completeness to issue the permit. This timeframe is
crucial for us as we will begin our project work in March of 2009. We are looking forward to working with you in your
review of the Southport Costal Stormwater Permit.
If you would - please comment on the project work we can conduct on -site prior to issuance of the stormwater permit. It
is our understanding that we are allowed to begin construction work that does not impact existing permitted stormwater
controls.
Please let me know if you have any questions.
Jim
Proiect's Overview:
■ Official Name is the North Carolina Emissions Control Project
■ The Project will spend approximately $75MM at our Roxboro and Southport Plants
■ The Project will modify our boilers and fuel handling systems
■ Boiler modifications will involve addition of a Mobotech overfred air system upgrade and new fuel feed
hoppers
■ Fuel Handling system modifications will involve addition of a truck dumper, fuel conveyor and pad storage
systems
■ Prior Project Planning involving installation of a ammonia injection system has been cancelled
■ Prior Project Planning involving the installation of a S02 solid adsorbent injection has been cancelled
■ No new Fuels or Chemicals will be introduced as part of the project
■ Plant operations will remain the same regarding power generation
Southport Plant - Project Stormwater Impact:
■ The Southport Plant will add a new 40,000 R.2 fuel storage pad
■ Addition of a truck dumper & Motor Control Center - approximately 1800 ft2
• The Southport Plant is proposing to add a new 1.5 mile new access roadway to the plant site
■ Total NEW impervious surface area is at approximately 1.63 acres
■ New Fuel pad area will be directed to the Plant wastewater basins ( wet detention basins ) which discharge
under a NPDES Permit #NC0065099. NPDES permit TSS limits will apply to the treated water discharged
from the plant.
■ New Roadway will be designed with adjacent "infiltration - conveyance ditches to manage stormwater. The
ditches will connect to the existing stormwater ditch system which conveys water to the Progress Energy
Brunswick Cooling Water Canal

Page 8
E. Record Keeping_
The operator shall maintain records on each individual blast describing: the total
number of holes; pattern\?f holes and delay of intervals; depth and size of holes;
type and total pounds of explosives; maximum pounds per delay interval; amount
of stemming and burden for1each hole; blast location; distance from blast to
closest offsite regularly occupied structure; and weather conditions at the time of
the blast. Records shall be maintained at the permittee's mine office and copies
shall be provided to the Department upon request. /
F. Excessive Ground Vibration/Air I Last Reporting:
If ground vibration or Air blast limi s are exceeded, the operator will immediately
report the event with causes and corrective actions to the Department. Use of
explosives at the blast site that produced the excessive reading shall cease until
corrective actions approved by the Departm t are taken. However, blasting
may occur in other approved areas within th permitted boundary. Authorization
to blast at the blast site may be granted at & time of the verbal reporting of the
high ground vibration or high air blast rea ing if the circumstances justify verbal
approval. Failure to report will constitute permit violation.
G. Flvrock Prevention:
The operator shall take all reasonabl6 precadtions to ensure that flyrock is not
thrown beyond areas' where the access is temporarily or permanently guarded by
the operator. Failure to take corrective measures to prevent flyrock and
repeated instances of flyrock shall be considered,a violation of the Mining Permit.
H. Flvrock Reporting_
Should flyrock occur beyond the permitted and guarded areas, the operator shall
immediately report the incident to the Department. rther use of explosives on
the mine site shall be suspended until the following a tions have been taken:
1. A thorough investigation as to the cause(s) of th incident shall be
conducted. /
2. A report detailing the investigation shall be provided to the Department
within 10 days of the incident. The report shall, at a minimum, document
the cause(s) of the incident along with technical and management actions
that will be taken to prevent further incidents. The report shall meet with
the approval of the Department before blasting may resume at the mine
site.

Roxboro Plant - Project Stormwater Impact:
■ The Roxboro Plant -will add a new 16,000 ft.2 fuel storage pad
■ Addition of a truck dumper & Motor Control Center - approximately 1800 ft2
■ The Roxboro Plant is proposing to add a ,112 mile new access roadway on the plant site
■ Total NEW impervious surface area is at approximately 2.1 acres
• New Fuel pad area will be directed to the Plant wastewater basins ( wet detention basins ) which discharge
under a NPDES Permit #NC0065085
■ New Roadway will be designed with culverts for stormwater runoff to the existing on -site drainage system
■ The Army Corp of Engineers ( Mr. Eric Alsmeyer ) is providing a 401 and 404 determination for this
stormwater conveyance.
Southport Stormwater Permits:
■ Southport submitted a stormwater renewal application in October of 2006 to renew its SW Permit
#NCS000348
■ Permit #NCS000348 is expired and Southport is operating under its permit shield
■ Southport is located in a MS4 Coastal region
■ With the Project disturbance of>1 acre - Southport is required to submit for a "Costal" Stormwater Permit
■ As part of the Coastal Stormwater Permit Application, a Erosion and Sedimentation Plan is being developed
for submittal with the SW Permit application
■ Our schedule is to submit the Southport E&S and SW applications by January 23rd
Roxboro Stormwater Permit:
■ Roxboro submitted a stormwater renewal application in October of 2006 to renew its SW Permit
#NCS000347
■ Permit #NCS000347 is expired and Roxboro also is operating under its permit shield
■ As Roxboro is NOT in a coastal region - it will not be submitting a new stormwater permit application
■ As the Project will be disturbing >1 acre, a Erosion & Sedimentation Plant will be submitted for Roxboro
■ Roxboro will adjust it Stormwater Management Plan to reflect the plant changes
■ Our schedule is to submit the Roxboro E&S application by January 23rd

12. Refuse Disposal
A. No on -site disposal of refuse or other solid waste that is generated outside of the
mining permit area shall be allowed within the boundaries of the mining permit
area unless authorization to conduct said disposal has first been obtained from
both the Division of Waste Management and the Land Quality Section,
Department of Environment and Natural Resources. The method of disposal
shall be consistent with the approved reclamation plan.
B. Mining refuse as defined by G.S. 74-49 (14) of The Mining Act of 1971
generated on -site and directly associated with the mining activity may be
disposed of in a designated refuse area. All other waste products must be
disposed of in a disposal facility approved by the Division of Waste
Management. No petroleum products, acids, solvents or their storage containers
or any other material that may be considered hazardous shall be disposed of
within the permitted area/he
C. For the purposes f this i ion of Land Resources considers the
following materials tole ' (in addition to those specifically listed
under G.S. 74-49 (14} ofing Act of 1971):
1. on -site generateddebris
2. conveyor belts
3. wire cables
4. v-belts
5. steel reinforced a
6. drill steel
D. If mining refuse is to)Ye permanently disposed within the mining permit
boundary, the follo� ng information mu be provided to and approved by the
Division of Land Resources rior to comriencement of such disposal:
1. the approximate boundaries and size f the refuse disposal area;
2. a list of 'refuse items to be disposed;
3. verification that a minimum of 4 feet of c ver will be provided over the
refuse;
4. verification that the refuse will be disposed t feast 4 feet above the
seasonally high water table; and
5. verification that a permanent vegetative grou dcover will be established
13. Annual Reclamation Report
An Annual Reclamation Report shall be submitted on a form supplied by the
Department by February 1 of each year until reclamation is completed and approved.
h ,.

Example Permit language for Alternative to Tier 2:
As an alternative to Tier 2 monthly monitoring prompted by three (3) consecutive exceedences of
copper (Cu), mercury (1-1g), or zinc (Ln) benchmarks, the permittee may continue quarterly
monitoring, AND either:
A. Submit to the Division, along with a summary of monitoring results to date, a strategy plan to
evaluate whether discharge concentrations are significantly higher than background levels.
That strategy plan may include, but is not necessarily limited to, any or all of the following:
1) Up- and downstream sampling;
2) Stormwater run-on sampling;
3) Evaluation of wind patterns and/or other meteorological data to characterize the risk of
regional background influence on concentrations in stormwater discharges;
4) Evaluation of National Atmospheric Deposition Program Mercury Deposition Network
(MDN) weekly data;
5) Sampling individual drainage areas to identify and isolate the largest pollutant
contribution areas;
6) Proposal for an alternative monitoring scheme to better characterize stormwater
discharges from the site and quantify site contribution in relation to background.
The background evaluation strategy plan shall outline an implementation schedule that
concludes no later than two (2) years from the date of submittal. At the conclusion of that
schedule, the permittee shall provide to the Division either:
1) A defensible demonstration that concentrations above the benchmark are attributable to
outside influences and/or elevated background concentrations of these metals and a
formal request for approval to maintain quarterly monitoring in the event Cu, 1-Ig, or %n
benchmark concentrations are exceeded in the future; or
2) The conclusion that elevated concentrations are attributable to industrial activities at the
plant and what structural and/or source reduction BMPs shall be implemented in
response. The information shall include which BMPs were chosen and why, and
timelines for submitting construction plans to DWQ, constructing, and/or implementing
those BMPs.
If results are inconclusive at the end of the two-year period, the permittee shall either:
1.) institute monthly monitoring for the remainder of the permit, or
2) maintain a quarterly monitoring schedule for the remainder of the permit (unless other
parameters trigger Tier 2') and immediately implement option B below.
B. Submit to the Division, along with a summary of monitoring results to data, a strategy plan to
identify the largest contributing areas of the plant site and implement structural BMPs to
address copper, mercury, and/or zinc concentrations in stormwater runoff discharges.
BMPs shall include structures such as bioretention cells or other engineered BMPs that have
demonstrated effectiveness in reducing such metal concentrations in stormwater. The permittee
shall provide a schedule for submitting construction plans to the Division for review, as well as a
plan to monitor and evaluate the effectiveness of the BMPs once installed.
Note: The above alternatives to Tier 2 response actions for these parameters to not negate
responsibilities of the permittee or potential actions of DWQ in response to any four exceedences
of a benchmark for any parameter during the term of this permit.

Roxboro Stormwater Permit NNCS000347
Best Management Practices Summary
Table 8.1 below summarizes the BMPs used at the Roxboro Plant. Potentially, exposed
materials at the plant include coal, petroleum products stored in existing ASTs, water
treatment chemicals, and ash. Coal for the boiler plant is stored outside in the coal pile
and coal pile runoff'is trea ed in the low volume wastewater system prior to discharge
(i.e., it is not drained to the stormwater system). Coal is brought in by rail and unloaded
daily through the coal chute and transported via conveyor belt to the coal pile. The risk
of coal dust entering the storm water via fugitive dust is minimized by using coal
unloading BMPs. Additionally, because the area drainage adjacent to the rail bed is
through vegetative buffers, the quantity of coal reaching the receiving water is minimal.
Water is sprayed onto the coal as it is unloaded from the rail cars in one of the.coal,�
unlo d nia g BMPs. Also, coal dust from the edges of the chute where coal is deposited is
swept up daily after unloading operations. These BMPs, coupled with the comparatively
limited surface area draining to the stormwater system in the western plant site, minimize
fugitive dust transport.
The risk of the petroleum products entering the storm system is low due to the use of
secondary containment that conforms to 40 CFR I L8(c)(2) and non-structural controls
(e.g., routing inspections) to prevent spills. Used oil is stored in two 300-gallon
aboveground storage tanks (AST) located at the Oil Storage Area. The used oil recycling
vendor removes the used oil as needed. Diesel is stored in a 300-galian AST inside the
Pump House and diesel, gasoline, and kerosene are each stored in 300-gallan AST's
located Oil Storage Area. There is a dedicated unloading bay at the Oil Storage Area and
temporary secondary containment is used at the Pump House during transfer operations.
The several chemical storage units in the Demineralizer Building are all equipped with
secondary containment and any spills arc routed to the Neutralization Tank and then the
Wastewater Basin for treatment. A spill kit is located inside the water treatment building.
There is a dedicated unloading bay at the Demineralizer Building. The Cooling Tower
Chemical Building also has chemical storage areas with secondary containment.
The risk of ash or ash residue entering the storm system is low due to the use of non-
structural controls (i.e. use of an ash pug -mill to wet the ash, an ash curtain and periodic
swceping/cleaning of the area). These methods minimize fugitive dust due to the ash
loading. When the ash loading is complete, the ash loading area floor is manually
sweepedlcleaned the tracking of ash residue.

Roxboro Stormwater Permit #NCS000347
Summary of Significant Changes in Industrial Activities
In 2004, the Primary Energy of North Carolina — Roxboro 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.

Dear Permittee:
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000347. This permit expires
on April 30, 2007. North Carolina Administrative Code (15A NCAC 2H.0105(e)) requires that an application for
permit renewal be filed at least 180 days prior to expiration of the current permit. In order to assure your continued
coverage under your permit, you must apply to the Division of Water Quality (DWQ) for renewal of your permit.
To make this renewal process easier, we are informing you in advance that your permit will be expiring. Enclosed
you will find an individual permit renewal application form, supplemental information request, and Stormwater
Pollution Prevention Plan certification.
Filing the application form along with the requested supplemental information will constitute your application for
renewal of your permit. As stated above, the application form must be completed and returned along with all
requested information by in order for the permit to be renewed by April 30, 2007.
Failure to request renewal by may result in a civil assessment of at least $500.00. Larger penalties may be
assessed depending on the delinquency of the request. Discharge of stormwater from your facility without
coverage under a valid stormwater NPDES permit would constitute a violation of NCGS..143-215.1 and could
result in assessments of civil penalties of up to $25,000 per day.
If you have any questions regarding the permit renewal procedures please contact Mike Randall of the Stormwater

Hello Jim,
Since I'm no longer working with the central office's stormwater permitting unit I'm sending this
response to my old supervisor, Bradley Bennett. Either he, or someone else in the unit will get back to
you about it as soon as they are able.
I have also cc:d my coworker here in Wilmington Regional Office, Linda Willis, about it since she will
most likely be consulted by the central office regarding your Southport facility before they respond to
you.
Take care,

I wanted to inform you of changes we are planning to.the Southport ( Stormwater Permit # NCS000348 ) and
Roxboro ( Stormwater Permit # NCS000347 ) plants to address future operation as impacted by both
business and environmental regulations( CAI ). The project changes are under design finalization for
installation completion by early 2009.
Your review of the proposed changes as discussed below would be appreciated. If you or an appropriate
person could please advise us of what actions you see are required to address these changes in our
Stormwater permits. As you may know, we submitted Stormwater Permit renewal applications at the end of
2006, but have not as of yet received the final permits for either plant. I wanted you to have this information
f 4 4/7/2008 9:27 AM

[Fwd: Re: NC Emissions Control Project - Stormwater Permit - NC...
as it may affect your permit renewal process.
As a quick review of our Southport and Roxboro plants, both 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.
A summary of the future changes under consideration involves the following:
Installation of a SNCR ( selective non -catalytic reduction ) ammonia 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
Installation of an Adsorbent Iniection System ( sodium carbonate ) for SO2 control
The sodium carbonate is a powder which will be pneumatically injected into the boiler & off -gas duct
Design will provide isolation of adsorbent fines from reaching wastewater system and stormwater contact
Installation of Fuel Processing E ui ment - grinders and additional conveyors
The fuel 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 of the above future changes to Stormwater Management:
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 SO2 adsorbent system will be designed as a closed.system to prevent any release that 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
I look forward to your input on these changes regarding application and permit issues...
Thank you.

Ken:
Re: North Carolina Emissions Control Project - Site Modifications - Impact to Stormwater Permits
Thank you for your council today regarding our Southport and Roxboro Plants future changes and the impact
these changes will have to our Southport and Roxboro plants Stormwater Permits.
As we discussed, relative to the Stormwater Permits ( renewal applications submitted in late 2006.- renewed
permits not yet issued ) and the proposed changes we are planning to begin and carry through to 2009 - there is no
ATC ( authorization to construct ) which you require associated with the plant's Stormwater permits.
Per our conversation, you indicated that ammonia monitoring would likely be incorporated as a requirement of
our SW Permit required stormwater run-off analysis based on our addition of the Selective Non -Catalytic
Reduction (SNCR) system use of aqueous ammonia (19% strength). As we discuss the ammonia monitoring
could be eliminated once sampling data sufficiently demonstrated no ammonia in plant stormwater discharge.
Regarding your question of wood fuel:
§ Wood is generally fresh cut and has not been stored for any appreciable time by suppliers.
§ Wood contains virtually no grass, leaves, or other flora that would readily decompose. The wood does
not have any rotting odor or appearance. The wood chips have a pleasant, fresh -cut wood smell and a
new wood appearance.
§ Since the wood fuel is cut from freshly cut trees from standing forests, there is very little chance for
surface contamination. Simply stated, the wood goes from standing trees to fuel chips in a matter of
hours. Nearly all of the fuel chips surface is fresh cut and has not been exposed to any source of
contamination
§ Fuel Chip Specifications:
- Shall be from unadulterated wood only. For purposes of this agreement, "Unadulterated Wood"
means wood that is not painted, varnished, oiled, waxed, or otherwise coated or treated with any
chemical. Plywood, OSB and resinated wood are NOT unadulterated wood.
Shall be approximately 1 % " x'/4" clean-cut chips
Shall contain a minimum amount of non -chipped material including sticks, branches, bark,
leaves, pine straw, sawdust, ground or shredded wood fibers, soil, sand, and non -wood debris.
Shall be free of stones, metal, and other foreign material, combustible or non-combustible .
Regarding your question of fuel storage on -site:
§ Wood storage on -site will be approximately I weeks supply - hence the longest duration expected for
wood to remain on site would be most likely 1-week and possibly up to 2 weeks based on fuel rotation
§ Based on the wood fuel specs and turn -over, contaminants and wood rotting affecting run-off is not
expected
§ The wood and TDF storage yards will consist of cement base pads with perimeter curbing and walls
§ The fuel yard pads will have 1 or more sumps to collect run-off
§ The sumps will pump accumulated run-off to the plant wastewater treatment system which discharges
through a NPDES permitted Outfall for each plant
As we discussed, this information will be consulted by your team once you begin renewal of our Southport and
Roxboro Stormwater Permits. We will be happy to address any further requests you have for information as you
move forward in your permitting process.

Mr. Moore,
Aisha Lau in the DWQ Wilmington office has forwarded your information
and questions to us in the Stormwater Permitting Unit. We're happy to
provide responses on the following three points with respect to your
stormwater permits at these two sites.
a) At each site you already have a Stormwater Pollution Prevention
Plan. Your obligation is to update each SPPP to reflect any significant
changes at the site that may affect stormwater runoff or the potential
for exposure of materials or processes to incident rainfall or
stormwater runoff.
b) While the expired permit is in review (and as Aisha reports, we have
a substantial backlog), please continue to abide by the provisions of
the permit.
c) As to the new site activities and materials resulting from the
addition of ammonia, sodium carbonate, and a grinder, we cannot offer a
comment on how these may affect our revision/renewal of your permit
based only on your email description of the changes. At the time that
we actively begin to process your renewals, staff from our office will
evaluate those changes in the context of the active review process.
Very generally, we will want to know what materials are now on site, and
are they exposed, or is there the potential for exposure, to rainfall or
runoff. Once we know what's on site, our reviewer will evaluate the
need to include those materials, or surrogates, in the monitoring
requirements contained in the renewed permit.
I'll be happy to speak with you on these points, or others, related to
our stormwater permits at these two facilities.

BG,
I concur that placing the info in the review file is the appropriate action now. Mr.
Moore asks for a response on the plant additions planned, but we really can't give
him any substantive response based on his email description of the changes. Any
meaningful response from us must be in the context of the full review, not in the
context of an email description.
So, when we do pick up the file, that's the time for the reviewer to see if these
changes might affect the sw permit. New materials on site appear to be: ammonia for
N0x absorbtion (possibly stored in the form of aqueous ammonia, a 29%
supersaturated pressurized liquid; or in the form of just the gas NH3 in pressurized
tanks) and I wonder if the NOx absorbtion will result in a HNO3 byproduct or
conversion of the gaseous NOx into a deposited solid that might be transported to the
receiving water; Na(CO3)2 for S02 absorbtion - first guess is that this is an
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. But, again, at this point we can't really give Mr. Moore
a substantive response on whether these materials will affect his stormwater permit.
Further, I concur that he does have an obligation to update the SPPP, and which
obligation is identified in his current permit.
I'll send Mr. Moore an email, on these two points: He must update the SPPP, and we're
not prepared without full review to suggest how/if the additional industrial
activities may affect the requirements of the renewed permit. Additional thoughts?

Bradley,
I think this is information the permit engineer needs for the renewal permits, but
I'm not sure there's any other action that's necessary right now. I'll make sure
these get into the files in Kelly's cabinet (these haven't been assigned yet). As
long as the existing SPPP is updated to reflect the changes in the meantime, I
don't think the company needs to do anything else. Ken, thoughts? -BG

Hello Jim,
Since I'm no longer working with the central office's stormwater permitting
unit I'm sending this response to my old supervisor, Bradley Bennett. Either
he, or someone else in the unit will get back to you about it as soon as they
are able.
I have also cc:d my coworker here in Wilmington Regional Office, Linda Willis,
about it since she will most likely be consulted by the central office
regarding your Southport facility before they respond to you.
Take care,

*Re: **EPCOR USA - North Carolina Plants - Future Changes - Permit Issue
Input Request*
I wanted to inform you of changes we are planning to the Southport (
Stormwater Permit # NCS000348 ) and Roxboro ( Stormwater Permit # NCS000347
) plants to address future operation as impacted by both business and
environmental regulations ( CAIR ). The project changes are under design
finalization for installation completion by early 2009.
Your review of the proposed changes as discussed below would be appreciated.
If you or an appropriate person could please advise us of what actions you
see are required to address these changes in our Stormwater permits. As you
may know, we submitted Stormwater Permit renewal applications at the end of
2 of 6 4/9/2008 10'58 AM

[Fwd: Re: [Fwd: Re: NC Emissions Control Project - Stor►nwater Perm...
,-►- -
2006, but have not as of yet received the final permits for either plant. I
wanted you to have this information as it may affect your permit renewal
process.
As a quick review of our Southport and Roxboro plants, bdth 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.
A summary of the future changes under consideration involves the following:
- *_Installation of a SNCR* { selective non -catalytic reduction ) ammonia
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
- *_Installation of an Adsorbent Injection System* { sodium carbonate ) for
S02-control
The sodium carbonate is a powder which will be pneumatically injected into
the boiler & off -gas duct
Design will provide isolation of adsorbent fines from reaching wastewater
system and stormwater contact
*_Installation of Fuel Processing Equipment_* - grinders and additional
conveyors
The fuel 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 of the above future changes to Stormwater
Management:*
- 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
r The S02 adsorbent system will be designed as a closed system to prevent
any release that 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
I look forward to your input on these changes regarding application and

Hello Jim,
Mike Randall forwarded your information request to my attention for
response.
A check of our database showed that your renewal package was received by
my section,on 10/31/06, which was in a timely manner. However, since my
section is currently very backlogged in our individual permit renewals
your renewal hasn't been assigned to an engineer for review yet. Soon
after it has been assigned you will receive an acknowledgement letter
from the engineer providing a timeline for the permit's reissuance.
in the interim period before your permit is reissued please continue to
operate as usual under your either soon to be expired or expired permit.
If you have any additional questions don't hesitate to ask.

Mr. Moore,
Aisha Lau in the DWQ Wilmington office has forwarded your information and questions
to us in the Stormwater Permitting Unit. We're happy to provide responses on the
following three points with respect to your stormwater permits at these two sites.
a) At each site you already have a Stormwater Pollution Prevention Plan. Your
obligation is to update each SPPP to reflect any significant changes at the site that
may affect Stormwater runoff or the potential for exposure of materials or processes
to incident rainfall or stormwater runoff.
b) While the expired permit is in review (and as Aisha reports, we have a substantial
backlog), please continue to abide by the provisions of the permit.
c) As to the new site activities and materials resulting from the addition of
ammonia, sodium carbonate, and a grinder, we cannot offer a comment on how these may
affect our revision/renewal of your permit based only on your email description of
the changes. At the time that we actively begin to process your renewals, staff from
our office will evaluate those changes in the context of the active review process.
Very generally, we will want to know what materials are now on site, and are they
exposed, or is there the pote— al or exposure, to rainfall o"" r runoff. Once a know
what's on site, our reviewer will evaluate the need to include those materials, or
surrogates, in the monitoring requirements contained in the renewed permit.
I'll be happy to speak with you on these points, or others, related to our stormwater
permits at these two facilities.

. Permit No. NCS000347
PART I
MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified below.
1. Stormwater Pollution Pr ven Wn Plan
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 II, Standard
Conditions, Section E.S. of this permit. The Plan shall include, at a minimum, the following
items:
a. Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(1) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name 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.
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(3) A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each outfall and
activities occurring in the drainage area, building locations and impervious surfaces,
and the percentage of each drainage area that is impervious. For each outfall, a
narrative description of the potential pollutants which could be expected to be
present in the stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(5) 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 II, Standard Conditions, Section
B.9.
Page 4

0 0 Permit No. NCS000347
b . 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:
(1) A study addressing the technical and economic feasibility of changing the methods
of operations and/or storage practices to eliminate or reduce exposure of materials
and processes to stormwater. Wherever practicable the permittee shall cover all
storage areas, material handling operations, manufacturing or fueling operations to
prevent materials exposure to stormwater. In areas where elimination of exposure
is not practicable, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials,
storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous
materials to prevent leaks and spills from contaminating stormwater runoff. If the
secondary containment devices are connected directly to stormwater conveyance
systems, the connection shall be controlled by manually activated valves or other
similar devices [which shall be secured with a locking mechanism] and any
stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, and visible sheens, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the observation, the
description of the accumulated stormwater and the date and time of the release shall
be kept for a period of five years.
(3) A narrative description shall be provided of Best Management Practices (BMPs) to
be considered such as, but not limited to, oil and grease separation, debris control,
vegetative filter strips, infiltration and stormwater detention or retention, where
necessary. The need for structural BMPs shall be based on the assessment of
potential of sources to contribute significant quantities of pollutants to stormwater
discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be
taken to limit or prevent erosion associated with the stormwater systems.
C. Spill Prevention and Response Plan. The Spill Prevention and Response Plan shall
incorporate a risk assessment of potential pollutant sources based on a materials inventory
of the facility. Facility personnel (or team) responsible for implementing the plan shall be
identified in the plan. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations.
d . Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
program shall be developed. The program shall document schedules of inspections and
maintenance activities of stormwater control systems, plant equipment and systems.
Inspection of material handling areas and regular cleaning schedules of these areas shall be
incorporated into the program.
e. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
Page 5

• Permit No. NCS000347
operations that have the potential to contaminate stormwater runoff. Facility personnel (or
team) responsible for implementing the training shall be identified in the Plan.
f. 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(s) assignments provided.
g. 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. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
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 pennittee shall provide certification in writing (in accordance with Part
II, Standard Conditions, Section B, #9) to the Director that the changes have been made.
h. Facility Inspections. Inspections of the facility and all stormwater systems shall occur at a
minimum on a semiannual schedule, once in the fall (September -November) and once
during the spring (April - June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be incorporated
into the Stormwater Pollution Prevention Plan.
Visual monitoring as required in I.A.2.g.(3) shall be performed in addition to facility
inspections.
i. Implementation. Implementation of the plan shall include documentation of all monitoring,
measurements, inspections and maintenance activities and training provided to employees,
including the log of the sampling data and of activities 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 years and made available to the Director or his
authorized representative immediately upon request.
2Minimum Monitodng andRel2orting-AgggLements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Water Quality.
a. 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.
b. Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry
weather flow shall be performed at all stormwater discharge outfall locations. All visual
monitoring shall be documented and records maintained with the Stormwater Pollution
Prevention Plan. The initial visual monitoring event shall be performed simultaneously
Page 6

0
0 Permit No. NCS000347
with the fast analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
C. For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm event (See Part 11,
Standard Conditions, Section A). Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit. If the stormwater runoff is
controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfall staining, visible sheens, and dry
weather flow are required, but analytical sampling shall not be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-
year, 24-hour storm (See Part H, Standard Conditions, Section A), the pond shall
be considered a non -discharging stormwater control system and not subject to
NPDES requirements, unless the discharge causes a violation of water quality
standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted no later
than January 31 for the previous year in which sampling was required to be performed.
e. Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
This permit regulates stormwater discharges. Non-stormwater discharges which shall be
allowed in the stormwater conveyance system are:
(1) All other discharges that are authorized by a non-stormwater NPDES pem-ut.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, discharges of uncontaminated potable water,
waterline and fire hydrant flushings, water from footing drains, flows from riparian
habitats and wetlands.
(3) Discharges resulting from fire -fighting.
If the storm event monitored and reported in accordance with this permit coincides with a
non-stormwater discharge, the permittee shall separately monitor and report all parameters
as required under the non-stormwater discharge permit and provide this information with
the stormwater discharge monitoring report.

term of the permit shall be calculated for each individual outfall and compared to the cut-off
concentrations listed below. If the arithmetic mean meets the specified cut-off concentration
condition for a given parameter, then the facility is not required to continue annual analytical
monitoring for that parameter at that outfall during the term of the permit unless a significant
change in facility operations or configuration occurs. If a cut-off concentration results in
discontinued analytical monitoring at an individual discharge outfall, the permittee is required to
maintain facility operations that ensure the continuation of stormwater runoff quality.
The permittee must perform analytical sampling during the fast and last year of the permit term
regardless of cut-off concentration conditions. Analytical results from sampling during the
final year of the permit term must be submitted with the permit renewal application.

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

1 Frequency: The first visual monitoring event during the term of the permit must be
performed during the initial analytical monitoring event. All subsequent visual
monitoring will be performed twice per year, once in the spring and once in the fall.
2 Monitoring Type: Visual monitoring requires a qualitative visual observation of each
stormwater outfall. No analytical testing or sampling is required.
