Stormwater Outfall Evaluation and Best Management Plan Summary E C E IVE

Outfall Evaluation
All outfalls have been evaluated and for non-stormwater discharges , no discharges have been
made from our site.
Best Management Plan Summary
Potentially exposed materials at Southport plant include coal, tire derived fuel, #2 fuel oil stored
in AST's , water treatment chemicals and ash. Coal is stored outside in the coal pile area and coal
pile runoff is treated in the volume in the low volume wastewater treatment system prior to
discharge. This runoff does not flow to the stormwater system. Coal is delivered by rail at the
North end of the facility and unloaded via a conveying sysyem to the storage area. The risk of
coal entering the stormater does exists. To minimize that risk coal unloading BMP's are used.
Water can be sprayed onto the coal if necessary during the off loading process to minimize
dusting. Also, the coal off loading area and equipment is cleaned after each off loading
operation. These BMP's , along with the limited surface area draining to the stormwater sysyem
In the coal offloading section of the plant minize any coal or coal dust carryover.
The risk of #2 fuel entering the storm system is low due to the use of secondary
contain mentstructures that conform to 40 CFR 112.8(2) and non-structural controls such as
routine inspections to help prevent spills. A properly certified vendor removed the oil as
required. #2 fuel oil is kept in a 1300 gallo tank located in a bermed area in the rail car offload
area and a 300 gallon bermed tank immediately outside of the diesel fire pump room. There is a
fuel oil vendor that supplies the Souhtport facility with #2 fuel oil as required.
All chemical storage and usage is limited to the demineralizer building, interior of the boiler
house, the waste treatment building and the RO building. Chemical storage areas are equipped
with either bermed storage locations or the containers are kept on chemical containment
pallets. In addition, there is a dedicated unloading bay at the demineralizer building and the
floor drains to the chemical sump in the RO building.

The risk of ash or any ash residue entering the stormwater system is low. This is due to the use
of dikes and non-structural controls. New ash conditioners have been installed . BMP's for the
machines have been substantially revised and improved based upon the results of two
engineering studies that have been performed.
In 2006 the Southport facilty added unadulterated fuel as an alternative fuel. The final
stormwater expansion ( permit # SW 8090511 ) was issued and completed in 2013. The wood is
stored on a pad and in the coal storage area. It directly runs off to the wastewater treatment
system via a concrete lined ditch. This prevents any wood runoff from reaching any stormwater
areas.
Changes to the Stormwater Prevention Plan
The Southport Stormwater Expansion ( permit # SW 8090511 ) was completed during 2013 in
accordancewoth the permit. This expansion included the installation of a sand filter. The permit
covers the construction , operation and maintenance of the BMP's within the built upon area.

Stormwater Outfall Evaluation and Best Management Plan Summary
Permit NCS000348
L�;E­I� FL;
FEB 0 3 2014
Outfall Evaluation CENTRAL FILES
DWQIBOC,
All outfalls have been evaluated and for non-stormwater discharges, no significant discharges
have been made from our site. The only non-stormwater discharge recorded in 2013 was a
break in the Reverse Osmosis reject line on July 7, 2013. Approximately 50 gallons of this water
made it into the storm drain and was promptly reported to Dean Hunkle at the NCDENR office in
Wilmington on July 8, 2013.
Best Management Plan Summary
Potentially exposed materials at Southport plant include coal, tire derived fuel, #2 fuel oil stored
in AST's, water treatment chemicals and ash. Coal is stored outside in the coal pile area and coal
pile runoff is treated in the low volume wastewater treatment system prior to discharge, This
runoff does not flow to the storm water system. Coal is delivered by rail at the north end of the
facility and and unloaded via a conveying system to the storage area. The risk of coal entering
the storm water exists. To minimize that risk coal unloading BMP's are used. Water can be
sprayed onto the coal if necessary during the off loading process to minimize dusting. Also the
coal offloading area and equipment is cleaned after each offloading operation. These BMP's
along with the limited surface area draining to the storm water system in the coal offloading
section of the plant minimize any coal or coal dust carryover.
The risk of #2 fuel oil entering the storm system is low due to the use of secondary containment
structures that conforms to 40 CFR 112.8©(2) and non-structural controls such as routine
inspections to help prevent spills. A properly certified vendor removes the used oil as required.
#2 Fuel Oil is kept in a 1300 gallon tank located in a bermed area in the rail car off load area and
a 300 gallon bermed tank immediately outside of the diesel fire pump room. An fuel oil vendor
supplies the Southport facility with #2 fuel oil as required.
Chemical storage and usage is limited to the Demineralizer Building, interior of the boiler house,
the waste treatment building and the RO building. All chemical storage areas are equipped with

Corporation
either bermed storage locations or the containers are kept on chemical containment pallets. In
addition there is a dedicated unloading bay at the Demineralizer Building and the floor of the RO
building drains to the chemical sump.
The risk of ash or ash residue entering the storm water system is low due to the use of dikes and
non-structural controls. New ash conditioners have been installed and the BMP's for the
machines have been substantially revised and improved based upon the results of two
engineering studies that were performed.
In 2006 the Southport facility added unadulterated wood as an alternate fuel. The final storm
water expansion (permit # SW8 090511) was issued and completed in 2013. The wood is
stored on a pad and in the coal storage area which directs runoff to the wastewater treatment
system via a concrete lined ditch. This prevents any wood runoff from reaching any storm water
areas.
Changes to the Stormwater Prevention Plan
The Southport Stormwater Expansion (Permit #SW8 090511) was fully completed during 2013 in
accordance with the permit. This expansion included the installation of a sand filter and the
permit covers the construction, operation and maintenance of the BMP's and built upon area.

CENTRAL FILES
Outfall Evaluation
DWR SECTION
All outfalls have been evaluated and for non-stormwater discharges , no discharges have been
made from our site.
Best Management Plan Summary
Potentially exposed materials at Southport plant include coal, tire derived fuel, #2 fuel oil stored
in AST's , water treatment chemicals and ash. Coal is stored outside in the coal pile area and coal
pile runoff is treated in the volume in the low volume wastewater treatment system prior to
discharge. This runoff does not flow to the stormwater system. Coal is delivered by rail at the
North end of the facility and unloaded via a conveying sysyem to the storage area. The risk of
coal entering the stormater does exists. To minimize that risk coal unloading BMP's are used.
Water can be sprayed onto the coal if necessary during the off loading process to minimize
dusting. Also, the coal off loading area and equipment is cleaned after each off loading
operation. These BMP's , along with the limited surface area draining to the stormwater sysyem
In the coal offloading section of the plant minize any coal or coal dust carryover.
The risk of #2 fuel entering the storm system is low due to the use of secondary
containmentstructures that conform to 40 CFR 112.8(2) and non-structural controls such as
routine inspections to help prevent spills. A properly certified vendor removed the oil as
required. #2 fuel oil is kept in a 1300 gallo tank located in a bermed area in the rail car offload
area and a 300 gallon bermed tank immediately outside of the diesel fire pump room. There is a
fuel oil vendor that supplies the Souhtport facility with #2 fuel oil as required.
All chemical storage and usage is limited to the demineralizer building, interior of the boiler
house, the waste treatment building and the RO building. Chemical storage areas are equipped
with either bermed storage locations or the containers are kept on chemical containment
pallets. In addition, there is a dedicated unloading bay at the demineralizer building and the
floor drains to the chemical sump in the RO building.

Capital Power
Corporation
The risk of ash or any ash residue entering the stormwater system is low. This is due to the use
of dikes and non-structural controls. New ash conditioners have been installed . BMP's for the
machines have been substantially revised and improved based upon the results of two
engineering studies that have been performed.
In 2006 the Southport facilty added unadulterated fuel as an alternative fuel. The final
stormwater expansion ( permit # SW 8090511 ) was issued and completed in 2013. The wood is
stored on a pad and in the coal storage area. It directly runs off to the wastewater treatment
system via a concrete lined ditch. This prevents any wood runoff from reaching any stormwater
areas.
Changes to the Stormwater Prevention Plan
The Southport Stormwater Expansion ( permit # SW 8090511 ) was completed during 2013 in
accordancewoth the permit. This expansion included the installation of a sand filter. The permit
covers the construction , operation and maintenance of the BMP's within the built upon area.
" I certify under the penalty of law, that this document and all attachments were prepared under
my direction or supervision in accordance with a system designed to assure that qualified
personnel properly gather and evaluate the information submitted. Based on my inquiry of the
person or persond who manage the system or the persons directly responsible for gathering the

All outfalls have been evaluated and for non-stormwater discharges, no significant discharges
have been made from our site. The only non-stormwater discharge recorded in 2013 was a
break in the Reverse Osmosis reject line on July 7, 2013. Approximately 50 gallons of this water
made it into the storm drain and was promptly reported to Dean Hunkle at the NCD_FN ce in
Wilmington on July 8, 2013.1

A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.
