Re- issuance Application
Dear Mr. Poupart:

INT SOHPrd r- onn M-'
The current N13DES permit for the Mayo Electric Generating Plant (Mayo) located in Person
County expires on March 31, 2011. Progress Energy hereby requests that the NPDES permit for
the facility be reissued. Enclosed is EPA Application Form 1 — General Information, EPA
Application Form 2C — Wastewater Discharge Information, and EPA Form 2F - Application to
Discharge Storm Water Discharges Associated with Industrial Activity, all in triplicate.
With re- issuance of the NPDES permit, Progress Energy requests the following:
Elimination of the effluent limitations and monitoring requirements for Barium,
Beryllium, Cadmium, Chromium, Fluoride, Lead, Vanadium, Cobalt, and Molybdenum
at Outfall 002. Based on monitoring data, particularly since the upgrade of the dry fly
ash handling system, it appears these parameters do not show reasonable potential to
exceed permit limitations.
• Elimination of the monitoring requirements for Nickel and Zinc from Outfall 002. Based
on monitoring data, particularly since the upgrade of the dry ash handling system, it
appears the parameters listed do not show reasonable potential to exceed water quality
criteria.
Elimination of the monitoring requirements from Outfall 009. Data collected since the
bioreactor system has been operating has adequately characterized this internal
monitoring point and has aided Progress Energy in their determination to eliminate this
source of wastewater. Additionally, pollutants of concern can be detected and quantified
at outfall 002 so continuation of the monitoring at internal monitoring point 009 has
served its purpose and is no longer needed to characterize the discharge to the receiving
water.

SEP, 2 7 2011
e Progress Energy Carolinas requests that the following condition be added to the renewed
NPDES permit,, replacing the current Biocide Condition located in Part'II 1. The purpose
of this condition is to formally recognize theguidance•and understanding we have
received from the Division,in the past, and to allow this permit to be consistent with other -
recently reissued permits.
BIOCIDE CONDITION
"Thepermittee shall not discharge any biocides that have not-been previously
approved in conjunction with ,the permit application For biocides not, previously
approved by the Division of Water Quahty, the permittee shall notify,the Director in
writing prior to use of these biocides. Completion of Biocide Worksheet Form 101 is
not necessary for those outfalls with-toxicity testing requirements "
Progress Energy Carolinas; Inc. also request the mixing,zone for chlorides be renewed ,for
the duration of the next °permit cycle,and monitored at the boat dock near -the discharge into `
the reservoir.
During the next permit cycle Progress Energy expects to initiate and complete several
projects designed to eliminate, certain wastewater streams•and associated, pollutants. One
will be to install a zero liquid discharge system (ZLD) whose purpose will be to evaporate
the majority of the waste water produced from the scrubber system. The' ZLD will produce
two waste streams, both will be,utilized in plant processes. The concentrated wastewater
will be used for moisture conditioning of fly ash prior to being sent ,to a monofill (landfill).
The second stream is a-clean distillate that will be utilized within the plant to partially,
replace water withdraw from Mayo Lake. The ZLD system will remove the FGD
blowdown stream from Outfall 002.
A second,project will be the conversion from a wet bottom ash handling system to �a dry
bottom ash handling system. The dry bottom ash will be delivered to an approved disposal
facility for coal combustion residuals (monofill).
A third project will be the,construction of aimonofill. The monofill will-,have a leachate
collection system and accept dry fly and bottom ash as well as gypsum and other coal
combustion residuals generated` from company facilities. The leachate collected will either
be used as process, water (to moisten the ash prior to or following placement in the
monofill). During the seasonal high rainfall periods, excess leachate will be collected,
stored and delivered to the inlet of the 'ZLD for additional processing or sentto a POTW.
Determination of which leachate disposal method will be used on a daily basis will depend
on the operational needs of the site and capacity of the permitted treatment system.
With regard to Section 116(b), of the CWA, the, Mayo Plant has,not made any changes to the
existing cooling water,intake structure that would change the status of compliance with,current
316(b) regulations. Once a new rule is promulgated by the EPA, Progress Energy will evaluate
the rule and its effects on the status of compliance of the existing cooling water intake structure.

The 'Mayo Electric Generating Plant is a coal -fired electric generating plant with one unit rated at a
maximum dependable capacity of 745 mw_ The plant is located in Person County, North Carolina and
uses No. 2 fuel oil for start up and stabilization of the boiler flame. Water is withdrawn from the Mayo
Reservoir as required ,to make up evaporative losses from the cooling tower, FGD Scrubber and boiler
water needs Makeup pumping rates from the reservoir are highly variable depending upon natural
weather conditions, generation load, plant operations, and evaporative loss
Chemical constituents contained in the discharges from this facility will, in part, be representative ,of the
naturally occurring chemical quality of the intake water, The discharges will also have chemical
constituents of such quality and quantity associated with similar discharges for fossil generating facilities
of this size, type, and in this geographical location Either all or part of "the elements enumerated ,in the
Periodic Table, either singularly or in any combination, may from time to time be contained in this
discharge More detailed descriptions of the individual discharges,described below
OUTFALL 001 - COOLING TOWER.SYSTEM
Approximately once per year the cooling tower ;basin and closed cycle cooling water system is
drained to dewater the system for maintenance The majority the water is pumped to the ash
pond Also approximately 2 MG is drained to the reservoir to dewater the system for
maintenance That discharge is monitored and reported to the state through, the monthly
Discharge Monitoring Report,(DMR) (Outfall 001)
DRY ASH HANDLING
D[y Fly Ash Handling
The plant has made an upgrade converting from primarily wet sluicing fly ash to primarily dry
handling of fly ash Dry fly ash handling is the primary method of fly ash disposal Fly ash is
handled dry by a pneumatic system and sent to the ash silo After being stored in the silo for a
short period �of'time the dry fly ash is loaded 'into trucks and is transported offsite to a permitted
monoflll If the dry ash handling system is out of service during plant operation periods, fly ash
will "be sent to the ash pond via the ash sluice system until the ,dry system is ,restored Such
occurrences are infrequent and brief
Dry Bottom Ash Handling (future)
The plant is planning to convert the bottom ash handling system from a wet sluicing system to a
system for handling bottom ash dry 'Dry bottom ash handling ,will become, the primary method of
bottom ash disposal Bottom ash will ,be handled dry by a pneumatic system and sent to the ash
silo After being stored in the silo fora short period of time the dry bottom ash will be loaded onto
trucks and is transported offsite to a permitted monofill Until such time as the upgrade to a 'dry
bottom ash handling system is complete, bottom ash will continue to be wet sluiced to the ash
pond
OUTFALL 002 — ASH POND TREATMENT SYSTEM
The ash pond receives ash transport water, coal pile runoff, storm water, cooling tower
blowdown, and various low volume wastes such as boiler blowdown, air pre- heater wash water,
boiler wash water, oily waste treatment, wastes /backwash water from water treatment processes,
plant area'wash down water, and equipment, heat exchangerewater The sewage treatment plant

Progress Energy Carolinas, Inc.
'Mayo Electric Generating Plant
National Pollutant Discharge Elimination System Permit Number NC0038377
also discharges to the ash pond The ash pond provides treatment by sedimentation, oxidation,
neutralization, equalization, and adsorption. A standpipe allows for overflow release to a small
secondary - settling basin for release into, Mayo Reservoir Due to alga blooms, the pH of ash
pond discharge canal is adjusted at the standpipe as needed
Ash Transport Water — During the brief and infrequent, time the dry fly ash handling system may
be out of service, water,for sluicing fly ash and bottom ash to the ash pond is withdrawn from the
closed' cycle °cooling water system The water in the closed cycle cooling water system is treated
with a dispersant for protection of W& cooling tower fill
Coal Pile Runoff — The coal pile runoff is routed to the ash, pond Flow volumes 'are related to
rainfall frequency and intensity. The annual daily average flow is based on a coal pile area of 5
acres, an annual average rainfall of 44 inches and a runoff coefficient' of 1 0
Cooling Tower Blowdown — Normally, ash transport water withdrawal from the closed cycle
cooling water system 'is sufficient to 'control total dissolved solids (TDS) in the cooling water and
serves as cooling ,tower blowdown During periods of, maintenance, some molybdate waste from
the closed cycle cooling water system is routed to the ash pond Also during periods of
maintenance, the,cooling tower basin is drained to the reservoir.
Limestone and Gypsum Piles = Storm water that falls on the limestone and ,gypsum storage piles
is,directed:to,the ash pond
Low Volume Wastes —
Oily Wastes — Drains containing oily wastes or water are routed to the oily waste basin
The discharge from the oily waste basin is routed through the oil —water separator where
the oil is removed and contained The treated water is then discharged to the ash pond
The fuel oil storage tank is in a containment area with a valve drain. The drain is routed
'to the oily waste basin. The collected oil is then managed and burned as used oil
according to the requirements of the facilities Title V Air Permit
Boiler_ Blowdown — The boiler water is treated with ammonia continuously when the
boilers are 'in service Sodium hydroxide is used when needed during abnormal
conditions Boiler blowdown is routed to the ash pond via the low- volume waste
conveyance
Water Treatment Wastes — Boiler make -up water and water for other uses is withdrawn
from the lake, treated by various processes, including clarification, sand filtration, carbon
filtration, and demiheralizafion/ reverse osmosis Finished water is stored in tanks until
needed Vanous,wastes generated from the water treatment such as filter backwash, and
spent regeneration chemicals such as sulfuric acid and sodium hydroxide are routed to
the ash pond via the low volume waste conveyance The plant's, Reverse, Osmosis
system produces a reject waste stream of approximately 150 gpm
Miscellaneous — Other miscellaneous ,sources such as wash -down water, water from
various plant drains, secondary containment drains, laundry activity and temporary hand
washing stations are routed to the ash pond via the low volume waste conveyance
Miscellaneous equipment heat exchanger water can be routed to the ash pond via the,
alternate cooling tower blowdown line if needed The air pre- heaters and boilers are
water washed infrequently The wastewater from the air pre- heaters wash and boiler
wash activity is discharged to the ash pond

Flue Gas Desulfurization Blowdown (Existing) — The Flue Gas Desulfurization (FGD)
system directs flue gas into an absorber where limestone (calcium carbonate) ;slurry is
sprayed Sulfur dioxide in the flue gas, reacts with the limestone slurry to produce
calcium sulfate (gypsum) This system reclaims any unreacted limestone slurry to be
reused in the absorber A small blowdown stream is used to maintain the chloride
concentration in the reaction tank The blowdown stream is discharged to a FGD settling
pond where suspended solids are reduced' prior to entering a bioreactor The bioreactor
utilizes, microbes to reduce soluble contaminants to insoluble forms that then precipitate
from solution The treated wastewater (bioreactor effluent Outfall 009) enters the ash
pond'second'ary settling pond prior°to outfall 002
Flue Gas Desulfurization Blowdown (future) — The Flue Gas Desulfurization (FGD)
system directs flue gas into an absorber where limestone, (calcium carbonate) slurry is
sprayed Sulfur dioxide in the flue gas reacts with the limestone slurry to produce
calcium sulfate (gypsum) This system reclaims any unreacted limestone slurry to be
reused in, the, absorber A small blowdown stream is used to maintain the chloride
concentration in the reaction tank The blowdown stream will be discharged to the FGD
settling pond where suspended, solids are reduced The discharge of the settling pond
will be treated in a thermal ,evaporation, zero liquid discharge (ZLD) system. The
ZLD concentrates the wastewater stream through the ,use of both mechanical and
steam energy to ,evaporate the, water. The concentrated wastewater will be used
for moisture conditioning of fly ash prior to being sent to a landfill. Clean distillate
from the process will be utilized'within,the plant-to partially replace water•withdraw
from Mayo Lake. The ZLD system will remove the FGD blowdown stream from
outfall 002.
Sewage Treatment Plant (STP) — Sanitary wastes are treated on -site by an extended aeration
treatment plant The plant is designed for 0 0125 MGD and consists of a screen, commutator,
surge tank, aeration tank, clarifier„ chlorine contact chamber, and a sludge holding tank Flow
from the system is dependent upon fluctuating demand due to variations in the number of
personnel om site When needed, residuals are disposed of off -site by a licensed contract
disposal, firm The STP effluent is routed to the ash pond via the alternate cooling tower
blowdown line
ASH MANAGEMENT AND RECLAMATION
From time to time fly and bottom ash in the ash, pond may be stacked or relocated within the
diked boundary.of the ash pond system to optimize treatment and storage
Iwthe event a practicable market becomes available, Progress, Energy may exercise the option of
reclaiming ash from the ash pond system In consideration of the scope of such an operation, no
additional discharges are expected to result from ash reclamation, efforts
HERBICIDE AND PESTICIDE USAGE IN THE TREATMENT SYSTEM POND
Herbicides may be used as needed to control nuisance aquatic'vegetation These. herbicides are
applied by licensed applicators, or persons under the immediate supervision of,a licensed
applicator, in accordance with the manufacturer's instructions- Herbicide usage is the least
preferred approach to,grounds maintenance The preferred grounds, maintenance approach is
strategic placement of gravel /stone and then mowing The occasional usage of herbicide is when
the preferred'methods are not'workmg or there is a personnel safety issuewith mowing or stone
placement

MAYO K40NOFILL (future)
The monof ll facility will be located across Highway 501 from the Mayo Plant, and comprises
approximately 659 ,9 acres total,with a 103 8 acre waste footprint, Phase 1 disposal area will have
a 5 year design life. The monof ll will have leachate collection and removal system (LSCR) that is
designed to meet, the requirements of the North Carolina Solid Waste, Management Regulations
The LSCR will include the following components:
• 24 -inch granular protective /drainage layer
• Network of leachate lateral and header collector pipes
• Double -sided drainage Geocomposite (GC) with a tnaxial geonet core
® Three leachate holding /storage tanks
Leachate collectedwdl either be used as process water (to moisten the ash prior to or following
placement in the monofdl) During therseasonal high rainfall periods excess leachate.will be
collected, stored and delivered to the inlet of the ZLD for additional processing or sent to a
POTW. Determination of which leachate disposal method will be used on,a daily basis will
depend on the operational needs of the site and capacity of the permitted treatment system
Leachate is proposed to be stored in three,tanks with a maximum capacity of approximately
348,000 gallons each'(total,site design capacity of approximately 1,044,000 gallons), as well as
existing process tanks and the NPDES ponds within the power generation facility will be used to
store leachate as needed
,STORMWATER RUNOFF
Outfall 004 — Drainage from Outside Storage Area
Outfall 004 is located ,on the northeast side of the plant site and drains, to the reservoir, using
catch basins, storm sewer and vegetated conveyance The industrial activity drained to this
outfall is primarily the facility's outside storage area 'mcludmg a loading dock Materials that are
not weather sensitive are stored in this area. These include empty lubricant drums, structural
steel, pipes, and some large equipment parts Virtually the entire area is loose gravel, except for
the concrete unloading dock There, is a storage shed in the back of the outside storage area

MATERIAL HANDLING
Four areas of coal handling were evaluated ,fortheir potential to create dust or particles. Also the
methods of controlling the dust were evaluated to ensure they were satisfactory in maintaining
dust control. The,areas evaluated were'the coal car unloading area, transfer boom, conveyor belt
system and coal pile.
Coal car unloading area - The, coal cars are positioned over a below grade open transfer
pit. The unloading area is equipped with a dust suppression system that is used to
minimize the generation of dust during-,coal car unloading. Water spray nozzles,are,
positioned such that as the coal car is unloaded into the transfer pit, the spray suppresses
any dust that could be created due to the unloading activity. Various conditions such as
wind, rain and coal condition-.dictate the need for the dust suppression system. Whenever
the operators feel the system is needed, it will `be used to prevent the creation of a dust
that could enter the storm water system. Storm water drainage from this area flows (via
the ash pond) to an NPDES discharge point 002,
• Transfer boom - Another operation where there is the potential to� create dust-is the
transfer of coal from the conveyor belts to the coal pile. In order to minimize dust and on
as need basis, the boom is.raised or lowered. Storm water drainage from this area flows
(via`the ash pond) to an NPDES discharge point 002.
• Conveyor belt system - The conveyor belt system has been evaluated for the{potential to
create dust. The possibility of the conveyor belt system to create dust or come in contact
with,storm water has been reduced because the system is covered. Efforts are,nia&to
ensure the conveyor belts stay,covered. Storm water drainage from the majority of these
areas flows (via the ash pond) to an NPDES discharge point 002.
• Coal pile - The,coal pile is known as a "live pile ", This is because of'the way the coal is
fed or reclaimed to the unit/boilers. Coal is pulled from the bottom of the pile, therefore
reducing the possibility of dust. Storm water that comes in contact with the coal pile is
routed to an NPDES discharge point 002 (via the ash pond). Storm water drainage from
this area flows ,(via the ash pond) to an NPDES discharge point 002.
In spring of 2009 the FGD system went into service. The FGD system requires individual
storage piles for the needed limestone and the produced gypsum. The storage piles, are located
west of the powerhouse block near the railroad tracks. Storm water that comes in contact with
limestone or gypsum is routed to an NPDES discharge point 002 (via the ash pond). The
limestone and ,gypsum materials are transported to and from the storage piles via dump trucks.
Gypsum haul trucks are required to be rinsed to remove any residual material prior to leaving the
plant -area. The truck rinse'activ,'ity�is conducted inside acontainment that processes the used
water through an oil water separator. Which then is routed (via the ash pond) to an NPDES

discharge point 002. During transportation, the dump trucks are required to keep the material
covered.
In 2010, hydrated lime injection system for flue gas conditioning. 'The system consisted of silo,
truck unloading equipment and injection equipment. The truck unloading area was designed
with a secondary containment that is utilized during the truck unloading process. Closed tanker
trucks deliver hydrated lime.
In 2011, magnesium hydroxide and calcium carbonate systems are being installed to reduce coal
combustion boiler slag impact. The truck unloading area consists of secondary containment
system that includes a sump thatallows,any released chemical to,be,collected and pumped into
thekcorrect;inside material tank. Any rain water can be released (after evaluation) outside of the
containment via sheet runoff.

Outfalls
Narrative Description
Outfall 004 — Drainage from Outside Storage
This, outfall is located on the northeast side of the plant, site and drains to the reservoir, using
catch basins' and storm sewer. The industrial activity drained to this outfall is primarily the
facility's outside storage area including a loading dock. Materials that are not weather sensitive
are stored, in this area. These include empty lubricant drums, structural steel, pipes, and some
large equipment parts. Virtually the entire area is loose gravel, except for the concrete unloading
dock. There is a small storage shed in the back of the outside storage area. This shed contains
any chemicals or oils'that would be stored in the area. The hazardous waste,central storage area
is located in this same shed. During construction projects, a portion of the outside storage area is
being dedicated' for a Ilaydown area for material storage which consists of structural steel and
concrete truck washout area. The concrete truck washout area is controlled to ensure no free
flowing,liquid leaves the area,or comes in.contact with any storm drains. Once the washed out
concrete is cured / dried the cured concrete is properly disposed. Due to mobile equipment, on-
site there is a potential for petroleum release.
Outfall 005 — Drainage from Industrial Area
The outfall is located on the northeast side of the facility and is the end point of the plant's
primary storm sewer system that drains the "power house block" of the plant. Including the area
around the boilers and turbine buildings,'precipitators, and the roofs.of the,machine shops,
administrative buildings, warehouse, parking lot, and miscellaneous support facilities, such as
the water supply treatment, ash storage silo, hydrated lime silo and transformers. Also draining
to this outfall through sewers is the grassed area intended for Unit 2 at some time in the future.
At various times during construction and maintenance projects, the Unit 2,area is being utilized
as structural steel and fabrication area. This area consists of gravel and grass areas. For outfall
005 the potential pollutants could be coal, coal ash, sediment, and the chemical make -up of the
rain water. Due to mobile, equipment, on -site there is a,potential for petroleum release.
In 2004.a ,SCR installation included the need to install anhydrous ammonia storage tanks,
including a truck unloading area within this area. The storage tanks and truck unloading areas
were both installed with secondary containments. The secondary containments included
normally closed valve drainage system that effluent is,routed to the ash pond and into a NPDES
discharge point 002.
SWP3 Outfalls.doc, revision 6 September 2011
DFP

During the 2009 FGD ,Scrubber installation an additional transformer was added to this area.
The transformer was installed with secondary containment with any collected rain water routed
to the existing oil waterdrainage and separation, system. Also during this same time period the
dry flyash collection system was upgraded including the load out system with a wheel wash
system. The load out system is designed to deposit conditioned.flyash into a dump truck. The
dump trucks' wheels are rinsed and the dump truck-'is covered prior to leaving the loa&out area.
In 2010, hydrated lime injection,system for flue gas conditioning: Theisystem consistedof silo,
truck unloading equipment and injection equipment. The truck unloading area was designed
with a,secondary,containmerit that is utilized during the truck unloading process. Closed tanker
trucks deliver hydrated lime.
Outfall 006a, b, c, d, e — Cooling Tower Area
Outfall 006 ,is located at the eastern end of `the site =and drains the area ,a"round the cooling towers,
including the roof of the chemical feed building and associated roads and parking areas. In the
cooling towerwea, there aretfive separate outfalls. All these,outfalls involve catch basins and
storm sewers that drain to swales and then to the reservoir. The cooling tower itself has a basin
for re- circulating cooling water and therefore, does not directly contribute to storm water•runoff.
For this outfall the potential pollutants could include sediment, mist from the cooling tower and
the chemical make -up of the rainwater. A malfunction of the cooling tower basin level and / or
the cooling tower make -up could result in potential release,of cooling tower water. Due to
mobile equipment, on -site there is a potential for petroleum release.
Outfall 007a, b — Drainage from Railroad Area
This outfall was removed from.Mayo's NPDES permit requirement effective date February
2001.
Outfall 010 - Main Plant Entrance Road
Starting at the,Boston Road and the main plant road intersection and traveling towards the plant,
the first approximate, 100 yards drains into Mayo Plant's ash pond. The remaining of the main
plant road drainage area drains to Mayo Lake. The central drainage pointffbfthe road is located
at a low point south of the entrance to the picnic,area entrance. The main plant entrance road is
being added ,to ,the SWP3 due to additional limestone and gypsum truck traffic (Spring 2009).
The potential pollutants for this area could be coal ash, limestone, gypsum, petroleum, hydrated
lime and the chemical make -up of the rain water. Limestone,delivery trucks arrive on site
covered. The gypsum trucks leaving'with product will be washed /rinse of any gypsum residue
before leaving the plant area. Also debris cover will cover material before leaving the plant area.
Due, to vehicle traffic there is a potential for petroleum release.
SWP3 Outfalls.doc revision 6 'September 2011
DFP

In 2009 recognizing the increase chemical /material transportation activity in this area, ,a daily
(excluding holidays and weekends) inspection of the plant entrance road was established.
In 2010, the installation of the hydrated,lime injection system for flue gas conditioningiresulted
in increased truck traffic. Closed tanker trucks deliver hydrated lime.
In 2011, coal conditioning system (magnesium hydroxide and calcium carbonate systems) are
being installed to improve coal combustion to improve boiler slag impact. The material is
delivered to facility via closed tanker trucks.

BEST MANAGEMENT PRACTICES (BMP's)
Structural
As need or new projects develop, any additional structural BMP are evaluated and identified.
The need will be based on the assessment of potential sources ,that could contribute significant
quantities of pollutants to storm water discharges ,and data collected through monitoring of storm
water discharges. Also, any concerns noted during visual inspections will be addressed at that
time.
Containment -/ Diversion
These measures require a physical structure or barrier to be installed, to divert storm water away
from potential pollutant sources or to contain potential pollutant sources. Diversion measures
function best where runoff can be directed to a.drainage channel and containment of the source is
impractical. Containment functions best in areas where material will be permanently stored,
handled, or used. Specific containment/diversion measures include:
• Segregation of the work area.
• Covering or enclosing the work area.
• Diking the work area.
• Diversion of storm water runoff, via pipes, and catch basins, or channels.
• Dust controls
Since 2000 the following projects that were evaluated and determined that structural,BMPs were
needed include the: following:
• 2004 SCR installation including. anhydrous ammonia storage tanks
o Anhydrous ammonia storage tanks - secondary containment
o Anhydrous ammonia delivery truck unloading area — secondary containment
• 2009 FGD Scrubber installation, and upgrade of dry flyash,hand'ling ,system
o Transformer installation — secondary containment going to oily waste collection
system
o FGD equipment location — inside with drainage back into system
o Relocation of FH double wall mobile equipment fuel oil tank — double wall. tank
placed inside >of -a secondary containment with lock drains that flow into the =oily
waste collection system
o Flyash delivered `into covered dump truck
o Flyash truck wheel wash system installed (liquid routed to ash pond and into 'a
NPDES discharge point 002)
® 2010 Hydrated lime
o Delivery truck — closed tanker
o Truck unloading — secondary containment
• 2011 Coal conditioning system (magnesium hydroxide and calcium carbonate)
o Delivery truck — closed tanker
SWP3 BMPs Structural doc revision 6 September 2011
DFP

o Truck unloading— secondary containment with sump to allow spill material to
place into product tank
o Product tanks located inside building with secondary containment including sump
to allow any spill material to be place into product tank
An example of a structural BMP presently in place at the Mayo Plant is that secondary
containment is provided for all above ground stationary oil storage tanks.
All areas with potential to have•erosion shall have temporary BMP's until the�area is stabilized
with permanent control devices. Temporary BMP's for erosion includes silt fences, sediment
traps and basins, rock check dams and diversion, dikes. Straw dams should not be used in place
of rock check dams or silt fences.. Permanent structural BMP control devices include rip -rap
lined channels, grass lined channels, and landscaping that provides adequate filtration.
Periodic vacuuming of storm,drain catch boxes will.be,conducted in high risk areas as:needed.

Concerning non storm water discharge from Outfall 005

• / i
Memo to file: 12520 R June,4, 2003

Non- Stormwater flow in Stormwater,0utfall 005
During dry periods, Stormwater Outfall 005 has a discharge that is non - stormwater related.
During the time period of 'July -- August 1996 an extensive investigation was conducted to try
and resolve where any water might be coming from. This investigation included walking lines
and catch basins looking-for anytowdrito the drainage�system, conducting visual observations
during non - normal work hours, and reviewing drawings of both stormwater and non- stormwater
drainage systems. In addition, dye was placed in nearby non - stormwater drainage systems to
ensure no cross - connections existed. Samples,of the water flowing from Out-fall 005 during dry
periods were collected and analyzed for pH, chlorine, appearance, odor and biocides. None of
the analyses indicated any industrial Water�present. It was observed that the flow would almost
stop after we had long period of no rainfall and the flow would increase if weghad recent rainfall.
The 1ast.catch basin before the outfall was observed not'to have any flow entering it, however, at
the final outfall there would beta small amount of water. After several hours of researching the
source of the water it was dedided that it must be,groundwater intrusion at a point between the
catch basin and the outfall.
During a site visit by Bradley Bennett, Supervisor of DWQ's Stormwater and General Permits
Unit, and accompanied,by Joanie Cooke (ESS), these investigations were discussed. He stated
that this,was not.unusual and appeared not to be concerned. Mr. Bennett was informed that we
document,on the Preventative Maintenance Visual Monitoring Worksheet that we suspect
groundwater as the source from this outfall (during-non-storm periods). He appeared to be,okay
with the statement.
