PART IV - EVALUATION AND RECOMMENDATIONS
Progress Energy (d.b.a. as Rowan County Power, LLC) is currently constructing a
combustion turbine generation facility in western Rowan County. A COC has been issued for
this facility (NCG500582) for the discharge of wastewater from an evaporative cooling process
for the combustion turbines. All domestic wastewater will be disposed of on -site through
subsurface disposal permitted through the Division of Environmental Health. Other wastewater
sources that may have pollutants such as oil/grease will be collected for disposal (pumped and
hauled) off -site at a waste oil reclamation facility.
The permittee has requested approval to construct WWT facilities that will be needed
during the second phase of this project. The proposed facilities will consist of dechlorination
facilities for cooling tower blowdown, and the associated effluent discharge line (to be
designated as 002). A complete list of the various waste streams discharging through both
outfalls 001 & 002, as well as the pollutants expected in each proposed waste stream can be
found in the permit application submitted by the applicant.
Pending a technical review and approval of the application and supporting information
submitted with this request, it is recommended that the permit modification be approved.

NCG500000 NOI
Rowan County Power, LLC Combustion Turbine Generation Establishment
Phase II
The phase II portion of this project will consist of the addition of 2 combustion turbine units, 2 heat
recovery steam generators and one steam turbine generator. A description of the combustion turbine
simple cycle process has been previously submitted with the NOI for phase I of this establishment.
Description of Combined Cycle
In a combustion turbine combined cycle process the heat remaining in the combustion turbine exhaust is
directed to a boiler called a heat -recovery steam generator (HRSG). The recovered heat is used as a heat
source to generate steam in a closed cycle system. This steam is expanded through a steam turbine
which turns a generator for electricity production.
The combined cycle phase of the Rowan County project will have two combustion turbines units, each
of which will have a HRSG. The two HRSGs supply steam to a single steam -driven turbine generator.
Once the steam has been used to turn the turbine and generator it passes through a shell and tube type
condenser where it is cooled with noncontact cooling water. The cooled, condensed steam (condensate)
is returned to the heat recovery steam generators to be converted back into steam to continue the process.
The condenser tubes are cooled by cooling water and the cooling water is directed to cooling towers in a
closed cycle system (no once through cooling water) where heat is dissipated. Attached is a water flow
schematic of the establishment which includes the phase II combined cycle component.
Phase If Combined Cycle Wastewater/Storm Water
• The primary discharge from the second phase of the project (combined cycle process) will be
cooling tower blowdown. The blowdown will contain sodium hypochlorite, corrosion inhibitors
scale inhibitors and acid/caustic for pH control. The blowdown will receive dechlorination
treatment as needed. Dechlorination will be by addition of sodium metabisulfite, sodium
bisulfite, sodium bisulfate or other similar dechlorination compound.
Routine HRSG cleaning — HRSG cleaning wastes generated during maintenance activities will
be pumped and hauled if generated using an acid process or discharged via outfall 001, or 002 if
a non-acid, physical process is used. Pollutants in the discharge resulting in the non-acid
cleaning process would consist of inorganic scale.
• HRSG Blowdown — HRSG blowdown will be introduced into the condenser cooling water
system as makeup water.
Rowan County Power, LLC CT Phase II
Attachment 2 Page 1

HRSG initial cleaning - The HRSGs require an initial cleaning/flushing to eliminate rust, mill
scale and any other similar accumulations. The total wastewater volume of this initial cleaning
will be up to approximately 500,000 gallons. This initial cleaning will be accomplished by one
of two procedures. One possible procedure will utilize citric or other acid and small amounts of
trisodium phosphate. This wastewater will be disposed of by.a pump and haul activity. The
second possible procedure will be accomplished without an acid process. This procedure will
use a wetting agent and hydraulic means to accomplish the cleaning/flushing. The wastewater
from this procedure will receive oil/water separation by a portable unit as needed and be
discharged via 002. Another option is a discharge via 001 after being settled in an existing
permanent storm water retention pond. A combination of the two treatment processes may also
be utilized.
Cooling system initial cleaning water — The condenser cooling system also requires an initial
cleaning/flushing similar to the HRSGs as described above. The volume of this initial cleaning
water will be approximately 1.4 million gallons. Characteristics of this cleaning water are
presented in Attachment 3. If the toxic characteristics of the waste stream are dissipated prior to
the need to discharge, the waste stream may be discharged via outfall 001, otherwise the waste
stream will be discharged via the dechlorination treatment and outfall 002.
Cooling tower drains — During maintenance activities the cooling tower basin may have to be
drained to various levels. The total basin contents will be approximately 850, 000 gallons.
Depending upon the activity and the amount of necessary drainage, the basin contents will be
handled in various manners. As depicted in the water schematic the basin contents may be fully
or partially routed: 1) through dechlorination and discharge via outfall 002, 2) back to the cooling
loop, 3) to a future cooling loop, or 4) to a permanent storm water sediment pond and possible
discharge via outfall 001 . These various alternatives depend upon how much water will be
drained, if the water contains a chlorine residual, if the sediment that has settled in the basin
requires removal to the storm water sediment pond, if the maintenance is minor and the water
can be stored in the system and other similar scenarios.
As with the simple cycle phase, other wastewaters such as fuel oil/water interface condensate,
false start materials and compressor wash water will be collected and pumped and hauled off site.
The water demineralization process will continue to occur in portable treatment units owned by a
contractor. Once a treatment unit requires regeneration it will be taken offsite and replaced with
a fresh unit. No water treatment wastes will be discharged from the site. Process units will be
rinsed when they arrive on site. This "rinse in" is the process of releasing processed water to the
ground before directing it into the storage tanks. This is done because it takes a few minutes for
the system to achieve the desired quality. The quality of this rinse water is somewhere between
potable and demineralized. Additionally, finished water may be drained to the ground from the
trailer units prior to departure. This must be done for weight considerations. Again, the quality
is somewhere between potable and demineralized. If needed the incoming water may be treated
by a filter process. Any backwash from the filters will be pumped and hauled.
• Exempt storm water that drains from the overall site will also be discharged.
Rowan County Power, LLC CT Phase II
Attachment 2 Page 2

• Laboratory drains will produce small amounts of wastewater similar to that found in boiler
blowdown and cooling tower blowdown. This drains will be routed to the HRSG blowdown
sump or to the septic tank system.
Various storage areas, equipment and process modules such as transformers, lube oil filters, fuel
oil modules, ammonia storage, water conditioning products, etc. will have containment areas
around them which will collect rain water. These containment areas will have manually
controlled valves at their outlets. The rain water collected in these containment areas will be
inspected for the presence of oil or other regulated substances prior to release to the ground. If
oil or other regulated substances are observed in the rain water the rain water will be pumped and
hauled or the rain water will be treated by various methods including a portable oil/water
separator prior to release to the ground.
There will be infrequent draining and cleaning of various process units, piping, components and
storage tanks during maintenance activities. The characteristics of the wastewater generated
from these activities should be within the,boundaries of those wastewaters contemplated by the
activities addressed by NCG500000. The drainage of these various units may be to ground or be
discharged via 001 or 002 depending upon the characteristics of the drainage.
• There may be very small quantities of miscellaneous discharges to the ground from system
pressure relief valves, Continuous Emissions Monitoring (CEMs) activities, condensates, etc.
Other Pollutants
• Phase H Combined Cycle - pollutants in the discharge of cooling tower blowdown will
consist of corrosion/scale inhibitors and chlorine which are addressed above. Other
pollutants may be Iron, Aluminum, Chloride, Nitrogen, Ammonia, suspended solids and
other similar substances normally found in public water supply water and cooling tower
blowdown.
• Additionally, traces of oil and grease may be found in the discharges from both phases of the
project due to the exposure of water to machinery. These trace amounts of oil and grease
should be within the range contemplated by the scope of the general permit NCG500000.

EVAPORATIVE COOLING WATER
The evaporative cooling water discharge (outfall 001) for the simple cycle phase
(phase I) will continue to contain no chemical additives. This activity is addressed via
Certificate of Coverage NCG500582.
COOLING TOWER BLOWDOWN
For the phase II combined cycle operation, the cooling tower blowdown discharge will
contain certain amounts of sodium hypochlorite, a scale inhibitor named Continuum
AEC, (or similar) and a corrosion, inhibitor named FloGard (or similar). The latter two
products are from BetzDearborn, Inc.. Sulfuric acid and caustic will be used to control
pH in the system. The cooling tower blowdown pH will be in the range of 8.0 SU.
Additionally, the cooling tower blowdown will contain those substances found in the
boiler blowdown.
The proposed cooling tower blowdown discharge at 002 will have a estimated maximum
volume of 0.24 MGD. The receiving stream will be (North) Second Creek as indicated
on the topographic map enclosed with this application. The 7Q10 of Second Creek at the
proposed discharge point is calculated to be 9.3 cfs (6.01 MGD) as per determination of
Curtis Weaver of the USGS — Raleigh, NC, October 19, 2001. The conservative IWC is
3.8 %.
MSDS and Biocide Worksheets for the products are attached.
BOILER BLOWDOWN
BetzDearborn, Inc. products proposed for use in the Heat Recovery Steam Generator
(HRSG) water are:
OptiSperse HP2650 (or similar) which is a phosphate/polymeric dispersant product used
for corrosion control.
CorTrol OS5607 (or similar) which is an oxygen corrosion inhibitor.
Steamate NA0540 (or similar) which is a neutralizing amine.
Attachment 3 Page 1

Biocide Worksheets and MSDS for these products are found in this attachment.
Additionally, ammonia may be used as a corrosion inhibitor/neutralizer. _
INITIAL FLUSHING AND CLEANING OF THE COOLING WATER SYSTEM
The circulating cooling water system piping and units will require an initial flushing and
cleaning in order to remove any corrosion products, mill scale, dirt, and oily residue.
Additionally, a prefilming step will be undertaken to lay a protective barrier on the piping
for protection against corrosion. The products that may be used for these activities
include BetzDearborn ( or similar) Continuum AEC, DeposiTrol, FloGard, Foamtrol,
and Spectrus. Other substances used may be Sodium Hypochlorite, and Sulfuric Acid.
If the toxic characteristics of the waste stream are dissipated prior to the need for
discharge, the waste stream may be discharged via outfall 001, otherwise the waste
stream will be discharged via the dechlorination treatment and outfall 002. The discharge
of this flush water will be a one or two time occurrence.
MSDS and Biocide Worksheets are attached for the BetzDearborn products.

-Alternatives to Direct Discharge -
Phase II Combined Cycle
a) Connection to a Regional Sewer Collection System An option evaluated for phase H
was to convey the cooling tower blowdown discharge to a Rowan County wastewater
treatment plant (WWTP). The WWTP is -located on Second Creek just south of Highway
70. Conveyance of the cooling tower blowdown to the WWTP would require the
construction of a conveyance line (possibly with lift station) to the WWTP or to its sewer
system, some form of flow equalization, a user agreement with the county, and user fees.
The WWTP is currently designed to treat 30,000 gpd and is permitted to expand to
90,000 gpd. It is receiving up to 8000 gpd during the school year. The volume of
cooling tower blowdown can be up to 240, 000 gpd. Due to the excessive volume of
cooling tower blowdown, this alternative of connection to the package plant was
eliminated.
Additionally, the City of Salisbury Sewer Use Ordinance prohibits the introduction of
cooling tower blowdown into their sewer system so this alternative was eliminated.
b) Subsurface Disposal — Attached is an evaluation by LAW Engineering and
Environmental Services, Inc. that addresses the feasibility of utilizing land application for
wastewater disposal for the build out of the phase II and phase III of the project. The
conclusions reached indicate that subsurface disposal is restricted from a technical
standpoint and is economically undesirable.
c) Spray Irrigation — The same conclusions reached in the LAW evaluation as presented
above are also applicable to spray irrigation.
Additionally, as the result of the evaluation of alternatives to discharge, Rowan County
Power, LLC proposes to use boiler blowdown water as part of the cooling tower makeup
water. rather than discharging these waters directly.

SUBJECT: CONCEPTUAL EVALUATION
LAND APPLICATION ALTERNTIVES
COOLING TOWER BLOWDOWN WATER
ROWAN COUNTY CT FACILITY
ROWAN COUNTY, NORTH CAROLINA
LAW PROJECT NO.30720-9-3702:05
Dear Mr. Holt:
As authorized by CP&L Work Authorization 2720-00024, LAW Engineering and Environmental
Services, Inc. (LAW) has evaluated land applications concepts for disposing of cooling Tower
blowdown water at the Rowan County Energy Complex site. The evaluation is part of the
requirements for an NPDES permit application. This letter reviews our understanding of the
project and presents the results of our evaluation.
PROJECT INFORMATION
CP&L is planning a steam turbine, two Heat Recovery Steam Generators and two additional
combustion turbines for its site in Rowan County. When these additions are completed, cooling
towers will generate water that cannot be recycled into the turbines. The quantity is estimated at
500,000 gallons per day or 347 gallons per minute (gpm). The water leaving the cooling towers
is expected to have only trace amounts of sodium hypochlorite and a scale/corrosion inhibitor.
CP&L is considering discharge of the water through piping to Second Creek southeast of the site
under an NPDES permit. Alternatives to the pipe disposal must be evaluated as part of the
NPDES permit application. The guidance document dated June 9, 2000, includes the following
options:
1. Connect to a Publicly Owned Treatment Works (POTW).
2. Connect to a privately owned treatment works.
3. Individual subsurface systems.
4. Community subsurface systems.
5. Drip irrigation -both surface and subsurface.
6. Spray irrigation.
7. Reuse.
8. Surface water discharge through the NPDES program.
9. Any possible combination of the above options.
CP&L is reviewing options 1,2,3,4,7 and 8. LAW was asked to assess the feasibility of options 5
and 6.

CP & L Conceptual Evaluation of Land Treatment
December 12, 2001 Rowan County Energy Complex
Page 2 of 5 Law Project No. 30720-9-3702-06
SITE INFORMIATION
• The Energy Complex site is located west of Salisbury, North Carolina on a tract of approximately
430 acres. Drawing No. 1 in the Appendix shows the site location. Present and planned
construction will occupy about 110 acres, 70 acres for the generation facility and 40 acres for the
substation. The existing and planned generation facilities are located in the north central portion
of the site, and the substation is located in the southeastern corner, adjacent to SR 1932.
Land within the property owned by CP&L has been considered for possible land treatment sites.
Purchase of additional, contiguous land has not beeoconsidered; however the general soil types
and topography are similar to the Energy Complex area, and our conclusions as to soil suitability
would apply to the adjacent contiguous land. The southern part of the site is occupied by a
substation and additional transmission lines. In addition, the soils in this area lie on steeper
slopes and contain wetland areas. Due to these obstacles, developing a land treatment site in this
area was not considered.
Three potential land application areas were considered and are shown on Drawing No. 2. These
are described briefly below:
Area 1: Approximately 35 acres south of Godby Road (SR 1952) to the northern perimeter of the
Energy Complex and east to the property line paralleling SR 1951. The topography of area 1 is
relatively level with elevations of 750 feet, mean sea level (msl). A drainage swale is present in
the southeast portion and was not included in the calculation of available acreage due to potential
for erosion.
• Most of this area is presently leased for agricultural purposes.
Area 2: An "L" shaped area approximately 56 acres in size located southeast of the Energy
Complex site. This area is generally sloping with 2 to 15 percent slopes with a small unnamed
creek passing through the northeast corner. The area is sparsely wooded with evergreens,
becoming covered with dense undergrowth along the eastem'boundary.
s`�
Area 3: This area is located southeA of the Energy Complex and contains approximately 22
acres. The area is gently sloping and currently wooded with mixed pines and hardwoods. A
drainage swale passes west to east along the southern portion of the area.
SUBSURFACE INFORMATION
The Rowan County Soil Survey, LAW's report of geotechnical exploration for the Energy
Complex site dated November 3, 1999 and additional reports dated December 23, 1999, July 7,
2000, and November 30, 2001, and a site visit on December 3, 2001 were used to assess
subsurface conditions. Estimates of the soil permeability were taken from the soil survey. The
geotechnical study did not include borings in the potential land application areas, but the
similarity of the geologic setting indicates extrapolation of geotechnical information is reasonable
for this conceptual evaluation.
Area 1: The soils in this area are mapped in the Rowan County Soil Survey as being Sedgefield
(SeB), Enon (EnB, EnC), Hiwasse (HWB2), and Cecil (Ce132) series. These soils generally lie on
2 to 8 percent slopes. These soils consist of sandy loams to clay loams and generally are
• underlain with clay that starts approximately 7 inches below the present grades. The permeability

of the Enon series soils is 2 to 6 inches per hour. The remaining soils as well as deeper soils in
• the Enon areas have lower permeabilities - 0.2 to 0.06 inches per hour.
Hand auger borings in Area 1 revealed a moist to wet, fine sandy clay.
According to the Soil Survey the depth to the high water is greater than six feet with the
exception of SeB, which will likely have perched water at depths of 1.0 to 1.5 feet during January
to March.
Area 2:. The soils in this area are composed of EnB, Mecklenburg loam (MbB), and Poindexter-
Mocksville complex (PxC) series. These soils lie on 2 to 15 percent slopes. According to the
Soil Survey, these soils have permeabilities of 2 to 6 inches per hour in the upper, layers,
decreasing to 0.2 to 0.06 inches per hour at depths of 7 inches and greater.
Hand auger borings in Area 2 revealed dry to moist sandy .clays and clayey sands. Spoils from
previous trenching activities indicate the upper layers are underlain by fine sandy clays.
Erosional gullies ranging in depth from 3 to 5 feet were also noted, thus indicating the potential
for excessive runoff and subsequent erosion exists for nonvegatated slopes. In addition to the
naturally occurring erosion, smaller channels (< 12") were starting to develop at the outfalls for
the storm water drainage pipes.
According to the Soil Survey the depth to the seasonal high water table is greater than six feet for
the soil series in Area 2
• Area 3: The soils in Area 3 are also EbB and EnC series, and their characteristics. are as
described above for Area 1.
SUITABILITY FOR LAND APPLICATION
Land application of wastewater is an accepted method of treatment. The rate at which the water
can be applied is controlled by the hydrogeologic system (the ability of the soils to transport the
water away without causing a rise of the groundwater table to the surface), the type of vegetative
cover, and the composition of the wastewater. For the cooling tower water, the wastewater is not
expected to contain significant amounts of chemicals that would limit the loading rate for typical
vegetation used in spray fields. The loading rate is limited by hydrogeologic considerations.
For any application system involving maintenance of crops, the water application has to occur in
cycles, allowing time between each cycle for drying and soil aeration so the plant roots are not
drowned. In addition, State regulations for land application systems require a storage lagoon with
capacity to store at least 30 days of wastewater for times when application is restricted by rainfall
and temperature conditions. For the expected water volume from the cooling towers, a 30 day
storage lagoon with a water depth of 10 feet would cover approximately 5 acres.
All three areas have restrictive horizons to downward percolation of infiltrating water. All three
areas are sloping with ,temporal streambeds present. Area 3 is relatively small and Area 2
contains the steepest slopes. Applying large amounts of water to these areas would potentially
result in excessive runoff. We have not considered these areas further, however a storage lagoon
could be considered within these areas.

CP & L Conceptual Evaluation of Land Treatment
December 12, 2001 Rowan County Energy Complex
Page 4 of 5 Law Project No. 30720-9-3702-06
To determine the required land application area, a permeability of 0.06 inches per hour was used
• as the design for downward flow. The value was selected based on the Soil Survey indicating this
permeability is likely within 7 to 18 inches of the ground surface for the soil series present.
Based on a flow rate of 500,000 gallon per day (347 gpm) and a maximum absorption rate of 1.4
inches per day (0.06 in/hr * 24 hrs/day), an application plot would need to be a minimum of 13
acres. Agricultural crops are unable to withstand 6 consecutive days of watering without root
damage; therefore, multiple plots must be used. Assuming an application period of 1 to 2 days
followed by 7 to 8 day rest period to allow for drainage and reaeration of the soil, approximately
10 application plots (130 acres) would be required to treat this amount of wastewater. Area 1
does not contain sufficient acreage, thus additional acreage would have to be purchased to
accommodate land application needs.
CONCEPTUAL COSTS
The costs of land application include the initial construction and equipment, the planting cost, and
the yearly maintenance. Rough estimates of construction and equipment are $4,000 per acre plus
the storage lagoon. For the approximate 130 acres of spray fields, the initial cost is roughly
estimated at $520,000. The estimated cost to design and construct a 5-acre lagoon is $225,000.
Additional costs would also be incurred to acquire additional acreage. Assuming the purchase of
130 acres at $2,500 per acre would be required, this cost is estimated at $325,000.
Engineering design and permitting costs would be on the order of $50,000. For comparison to
pipe discharge initial costs, we recommend using a figure of $1,250,000.
Maintenance cost is a function of the crop type. Grass or forage crops require continuous
• maintenance (mowing, baling, hauling) while tree crops require much less after the initial two to
three years to establish a tree canopy.
We have not developed a yearly maintenance cost estimate because the initial costs are well
above our understanding of a pipe discharge installation cost. We understand from discussions
with other engineering firms that a 60-acre site with grass cover maintained in Ahoskie requires
five full time personnel operating 4 tractors year round.
•
CONCLUSION
Based on our conceptual evaluation, the presence of a shallow restrictive zone limits the
suitability of the site for land application by spraying, drip irrigation or direct infiltration systems.
From a cost standpoint, the initial construction costs for a spray irrigation project would appear
high relative to the likely costs of a pipe discharge. Annual maintenance costs for spray irrigation
vary with the type of vegetation, but are high relative to maintaining a discharge pipe.
From our review, we conclude that land application, either by spray irrigation or drip methods, is
not technically supportable or economically feasible for the volume of water that needs to be
disposed at the Rowan County Energy Complex site.

Technology Fact Sheet
Dechlorination`
DESCRIPTION
Dechlorination is the process of removing residual
chlorine from disinfected wastewater prior to
discharge into the environment. Sulfur dioxide is
most commonly used for dechlorination and is the
major focus of this fact sheet. Some dechlorination
alternatives include carbon adsorption, sodium
metabisulfite, sodium bisulfite, and hydrogen
peroxide. Sodium metabisulfite and sodium
bisulfate are mainly used in small facilities because
these materials are more difficult to control
compared to sulfur dioxide. Hydrogen peroxide is
not frequently used because it is dangerous to
handle (WEF, 1996).
APPLICABILITY
Chlorination has been used widely to disinfect
wastewater prior to discharge since passage of the
1972 Federal Water Pollution Control Act
(WPCA), (Finger et al., 1985). In the first years
following the WPCA, disinfected wastewater with
significant levels of residual chlorine was routinely
discharged into the receiving waters. It became
clear, however, that residual chlorine is toxic to
many kinds of aquatic life (see, for example,
Mattice and Zittel, 1976, and Brungs, 1973).
Moreover, the reaction of chlorine with organic
materials in the water formed carcinogenic
trihalomethanes and organochlorines (WET and
ASCE, 1991). As a result, dechlorination was
instituted to remove residual chlorine from
wastewater prior to discharge into sensitive aquatic
waters.
Dechlorination minimizes the effect of potentially
toxic disinfection byproducts by removing the free
or total combined chlorine residual remaining after
chlorination. Typically, dechlorination is
accomplished by adding sulfur dioxide or sulfite
salts (i.e., sodium sulfite, sodium bisulfite, or
sodium metabisulfite). Carbon adsorption is also an
effective dechlorination method, but is expensive
compared to other methods. Carbon adsorption is
usually implemented when total dechlorination is
desired.
Specific design criteria and monitoring
requirements for a particular region are determined
by the state regulatory agency. Typically, the
treatment plant's National Pollutant Discharge
Elimination System (NPDES) permit limits effluent
chlorine residual and toxicity. Currently, many
permits require very low or "non -detect" chlorine
residuals, making dechlorination critical.
One important alternative to dechlorination is to
achieve disinfection without the use of chlorine.
Other means of disinfection, such as ozone or
ultraviolet disinfection, have also become
increasingly prevalent (U.S. EPA, 1986; Blatchley,
E.R. III, et al., 1996).
ADVANTAGES AND DISADVANTAGES
Advantages
• Protects aquatic life from toxic effects of
residual chlorine.

Disadvantages
Chemical dechlorination can be difficult to
control when near zero levels of residual
chlorine are required.
Significant overdosing of sulfite can lead to
sulfate formation, suppressed dissolved
oxygen content, and lower pH of the
finished effluent.
DESIGN CRITERIA
Chemistry of Dechlorination by Sulfonation
Sulfur dioxide (SO,) is a corrosive, nonflammable
gas with a characteristic pungent odor. At
atmospheric temperature and pressure, it is a
colorless vapor. When compressed and cooled, it
forms a colorless liquid. Sulfur dioxide is supplied
as liquefied gas under pressure in 100 or 150 pound
containers and one -ton cylinders. As an alternative
to sulfur dioxide gas, various dry chemicals are
available which form sulfiir dioxide in solution.
These include sodium sulfite ILa SO odium
metabisulfite (Na,S205) sodium bisulfite
(NaHS03) a 38 ercent aqueous solutio�nodiii
mmetabisulfite, and soiumthiosulfate203),
a g o ers (Lind, 1995).
When dissolved in water, chlorine hydrolyzes to
form hypochlorous acid (HOCI) and hypochlorite
ions (OCI- ) which, taken together, are referred to as
"free chlorine." (Free, uncombined chlorine, Cl,, is
rarely found in wastewater since the conditions of
formation are relatively extreme [Lind, 1995]).
Once formed, the free chlorine reacts with natural
organic matter in water and wastewater to form
chlorinated organic compounds. The free chlorine
also combines with ammonia to form mono-, di-,
and trichloramines in quantities dependent on the
ratio of chlorine to ammonia nitrogen (Lind, 1995).
When either sulfur dioxide or sulfite salts are
dissolved in water, aqueous sulfur compounds in
the +4 oxidation. state are produced, often notated
S(IV) (Helz and Nweke, 1995). The S(IV) species,
such as the sulfite ion (S0;'), reacts with.both free
and combined forms of chlorine, as illustrated in
equations (1) and (2) (WEF, 1996):
(1) S03-2 + HOCI • SO4 - - + Cl- + H`
(2). S03 + NH,CI + H,0 • SO,-2 + Cl- + NH41
Since free chlorine and inorganic chloramines react
rapidly with S(IV) (Helz, 1998), a short contact
time of one to five minutes is considered to be
sufficient; nevertheless, complete blending at the
point of application is essential for effective
dechlorination (WEF and ASCE, 1992).
Proper dosage is critical to produce a non-'
detectable chlorine residual. On a mass basis, 0.9
parts sulfur dioxide (or 1.46 parts NaHS03 or 1.34
parts Na,S,05) is required to dechlorinate 1.0 part
residual chlorine. In practice, approximately a one-
to-one ratio is used (WEF, 1996). Dosing in. excess
must be avoided because excess sulfite can react
with dissolved oxygen (four parts sulfite to one part
oxygen) in the wastewater to produce sulfates,
potentially leading to reduced dissolved oxygen
concentrations and low pH levels in the finished
effluent for high levels of overdose (WEF, 1996).
Careful process control will help prevent
overdosing. _
Equipment for gaseous sulfonation
Equipment required for gaseous sulfonation using
S02 is similar in design to that used for
chlorination, except that the materials are chosen
for their application -specific chemical resistance
(WEF, 1996). The four basic components of the
system include: sufficient gas supply with
automatic switch -over between cylinders; a
metering system, usually consisting of a vacuum
regulator and a rotameter for feed rate control; one
or more injectors with check valves; and a residual
analyzer to measure and transmit a continuous
signal proportional to the chlorine residual in the
sample stream.
In small concentrations, exposure to SO, can cause
eye and throat irritation. In high concentrations,
exposure can produce a suffocating effect caused by
irritation to the upper respiratory tract. Therefore,
facility design should include features for safe
storage, handling, and use of sulfur dioxide. The
chlorine and sulfur dioxide cylinders should be
located in separate rooms and stored in a well-
j/oWA-2.-'bc-4-63-M6-00�
A ITAc eeJ-I oZ PA I C � %

ventilated, temperature -controlled area so that their
temperature never drops below 18 or exceeds 70
degrees Celsius. Gas leak detectors are necessary in
the storage area and the sulfonator area. An
emergency eyewash shower and self-contained
breathing apparatus should also be provided. All
personnel should receive emergency response
training. Facilities with more than 1,000 pounds of
SO, stored on -site must abide by the Process
Management Safety Standard in the OSHA
regulations (OSHA, 1998). "
Effect of Temperature on Gas Withdrawal Rate
The room temperature where the gas supply is
located should be maintained around 70 degrees F
to ensure optimal gas withdrawal rates (WEF,
1996). At this temperature, the maximum safe
sulfur dioxide gas withdrawal rate is approximately
2 lb/hr for a 150 lb container, or 25 lb/hr for a ton
container. Higher temperatures are required to
achieve higher continuous gas withdrawal rates.
Strip heaters or liquid baths may be used for this
purpose.
Injector Selection
Proper selection of the injector is critical for proper
system operation. The injector produces a vacuum
that draws sulfur dioxide gas through the
sulfonator. It then mixes the gas with dilution
water supply and injects the solution into the
wastewater. To properly size the injector, the back
pressure on the injector at the point of application
and the water supply pressure required at the
injector must be determined. The injector can
either be installed in a pipe or an open channel. As
an alternative to the typical vacuum regulator with
injector system, a chemical induction system may
be used to introduce the sulfur dioxide directly as a
gas.
Control
At present, few options exist for reliable long-term
measurement of sulfite salts or close -to -zero levels
of residual chlorine in the finished effluent (ASCE
and WEF, 1991). In recent practice, the only viable
method for continuous residual chlorine
measurement has been the amperometric technique,
but this suffers from loss of accurate calibration at
low concentrations (Finger et al., 1985). Though
some sources claim to have developed process
control methods employing oxidation reduction
potential (ORP) as an effective stand-in for direct
chlorine measurement (Bossard et al., 1995), other
sources assert that ORP is an inappropriate
technique for this purpose (WEF, 1996). For these
reasons, control of dechlorination—particularly
dechlorination to zero residual —has been
problematic. Treatment plant operators have had to
work around this limitation using various control
strategies.
One commonly used strategy is the use of a "zero -
shifted" or "biased" analyzer (WEF, 1996; Nagel,
1994). In this scheme, a residual chlorine analyzer
is used and a known concentration, X, of chlorine
is added to the effluent sample to be analyzed. In
this technique, the "zero' point is shifted by the
value of X, and residual chlorine or sulfur dioxide
can be inferred from the result of sample analysis.
Two types of control systems are often used for
dechlorination (WEF, 1996). A "feed -back"
control system can be used at treatment plants that
are not required to dechlorinate their effluents to
zero levels. With feed -back control, an analyzer
measures the chlorine residual at a point
downstream of the sulfur dioxide addition. This
signal, along with flow rate data, is relayed back to
the sulfonator and the dosage is automatically
adjusted accordingly. Though there is a lag time
between the injection point and the sample point,
the lag is deemed to be minimal since the
dechlorination reaction occurs almost
instantaneously.
For treatment plants that must discharge a zero
concentration or undetectable residual chlorine but
are not equipped with biased or direct reading
analyzers, feed -back control is typically not feasible
(WEF, 1996). Therefore, such dechlorination
systems often use a "feed -forward" control that
measures the chlorine residual after disinfection but
prior to the addition of sulfur dioxide. A mass flow
signal is sent to the sulfonator from the in -line
analyzer and thesulfur dioxide delivery rate is
automatically calculated and adjusted to the ratio
required for proper dechlorination of the effluent.
/ 01-JA-�Z-JC4/-3-ME-002-
Atr^J,,vk"- a. pay_ 3 9 4

Instrumentation combining feed forward control
with biased analysis may provide an effective
method to dechlorinate the effluent to low-level
residuals. Another useful design feature involves
using an automated chlorine flush of the sample
line (with sulfonator response temporarily locked).
This procedure prevents the buildup of slime and
algae in the sample line, thus eliminating chlorine
demand in the line which can suppress residual
chlorine analyzer results (Nagel, 1994).
Sample Calculation
Given: Peak flow = 20 mgd. Measured
chlorine residual is approximately
1.5 mg/L.
Calculate: Maximum dosage of sulfur dioxide
needed per day. Assume a 1:1 ratio
of SO, to CIZ.
Capacity = (flow rate) x (Cl, residual) x
(dosage ratio) = (20 mgd) x (1.5
mg/L C1Z) x (8.34
lb/Mgal.mg/L)x(1 mg/L SO, per
mg/L Clz) = 250 lb SO, per day
maximum.
Using Sulfite Salts
Upon dissolution, sulfite salts produce the same
sulfite ion as sulfur dioxide gas (WEF, 1996).
While the gas has the highest dechlorinating
efficiency per net pound of the product added, many
smaller facilities choose to use one of the sulfite
salts because of the storage, handling, feeding, and
safety problems associated with using gaseous
sulfur dioxide on a large scale. Of all the sulfite
salts available, sodium metabisulfute has the lowest
addition rate required for dechlorination (Lind,
1995).
PERFORMANCE
Sulfonation has been widely considered effective
for removal of chlorine compounds in disinfected
wastewater and reduction of toxicity for aquatic
life. Nevertheless, two studies have suggested that
disinfected/sulfonated wastewater poses a hazard to
some sensitive aquatic species (Hall et al., 1982;
Rein et al., 1992). Furthermore, one estimation of
chlorine removal efficiency is from 87 to 98 percent
(Helz and Nweke, 1995), leaving the actual residual
chlorine following sulfonation above most
regulatory limits.
Chloramines tend to be longer lived and less
reactive than other chlorinated species in
wastewater (Lind, 1995). While hydrophilic
organic chloramines have been thought of as
generally nontoxic, Helz and Nweke have found
that the S(IV) fraction resistant to dechlorination
may be composed of hydrophobic secondary amines
and peptides, including chloramines, suggesting
possible toxicity for aquatic organisms in receiving
streams. The authors note that this fraction of
S(IV)-resistant chlorine has been overlooked
because the dechlorinating agent interferes with
standard analytical methods for total chlorine (Helz
and Nweke, 1995). Continued testing is underway
to further characterize the dechlorination-resistant
fraction and its effects on aquatic organisms (Helz,
1998).
OPERATION AND MAINTENANCE
Components of the pressure manifold —especially
flexible connectors, valves, and the injector and
solution system —are the most likely to need repair
(WEF, 1996). In view of this, these components
should be inspected at least every six months.
Additionally, diaphragms and injector gaskets
should be replaced every two years. The gasket
should be replaced each time the joint is broken in
a gasketed pressure connection. Asbestos fiber
gaskets are not recommended because they often
do not seal properly. Used gaskets should never be
re -used. Springs should be replaced according to
the manufacturer's instructions.
Spare parts —especially parts for the pressure
manifold —and standby equipment, should be kept
on hand to prevent significant down time in the
event of equipment problems. Because sulfonators
are configured with the same components as
chlorinators, some plant engineers tend to treat
sulfonators as standby chlorinators (WEF,- 1996),
but this practice should be avoided. Chlorinators
and sulfonators are composed of different polymeric
materials (sulfmators typically of PVC and
lRO cJA - a- DC14-05 —ME— 002—

chlorinators of ABS plastic), each chosen for
application -specific chemical resistance. Use of
non -chemical resistant materials with chlorine or
sulfur dioxide gases can lead to equipment failure.
Moreover, equipment misuse leading to accidental
mixing of chlorine and sulfur dioxide gases can
lead to an exothermic chemical reaction and
equipment failure.
Water can be used to clean most component
surfaces. For buildup of impurities or for stains, a
dilute hydrochloric (muriatic) acid solution may be
necessary (WEF, 1996). Following cleaning, the
components must be thoroughly dried before they
are reassembled. Drying is best done using
compressed dry air or nitrogen.
COSTS
Costs for a dechlorination system vary widely
depending on particular site conditions. Detailed
estimates are not included here because they may be
misleading. One of the largest overall cost
variables is whether an existing facility is being
upgraded to accommodate dechlorination or
whether the chlorination/ dechlorination system is
a component of new plant construction. Site -
specific construction costs can vary by hundreds of
thousands of dollars, depending on the type of
project.
Table 1 gives a cost example of a 2,800 ppd gas
sulfur dioxide system installed in 1994 in Florida.
Cost considerations must also include the cost of
equipment, installation, labor, and operation and
maintenance. The type of dechlorination agent to
be used will affect both the equipment and chemical
costs. For large plants, sulfur dioxide gas is
typically the agent of choice because of its
dechlorinating efficiency on a per pound basis.
However, as previously mentioned, many smaller
plants may find that storage, handling, and safety
issues offset whatever gains in efficiency can be
obtained by using compressed gas.
Effective process control will help prevent chemical
overdosing and allow for chemical cost savings.
One 40-mgd facility has reported a savings of
$7,000 per month —a greater than 1,000 pound per
day reduction in SOZ use (>50%) and a greater than

I am writing in response to your phone call to our offices on November 6, 1998. From November 1, 1993
to present, your facility was covered under NCG020000. On June 10, 1997, you applied for permit
renewal and remitted the required fee. On August 31, 1997, the general permit expired. By operation of
law (pursuant to NCGS 150B-3(a)) you have continued coverage under NCG020000 until a new general
permit is issued by the Department since you applied for renewal prior to the expiration of NCG020000.
If you have any further questions concerning this issue or if the Department can be of any further
assistance, please feel free to contact Darren England at 919-733-5083, ext. 545.

Certificate of Coverage NCG020207
General Permit NCGO20000
Formerly NPDES Permit NCO081396
Rowan County
The Division of Environmental Management has recently evaluated all existing individual permits for potential
coverage under general permits currently issued by the Division. 15A N.C.A.C. 2H .0127 allows the Division to
evaluate groups of permits having similar discharge activities for coverage under general permits and issue .
coverage where the Division finds control of the discharges more appropriate in this manner. The Division has
determined that the subject discharge qualifies for such coverage. Therefore, the Division is hereby issuing the
subject Certificate of Coverage under the state-NPDES general permit no. NCG020000 which shall void NPDES
Permit NC0081396. This Certificate of Coverage is issued pursuant to the requirements of North Carolina and the
US Environmental Protection Agency Memorandum of Agreement dated December 6,1983 and as subsequently
amended.
If any parts, measurement frequencies or sampling requirements contained in this general permit are unacceptable to
you, you have the right to submit an individual permit application, associated processing fee and letter requesting
coverage under an individual permit. Unless such demand is made, this decision shall be final and binding. Please
take notice this Certificate of Coverage is not transferable. Part II, E.4. addresses the requirements to be followed
in case of change of ownership or control of this discharge.
In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, the
Permittee shall take immediate corrective action, including those as may be required by this Division, such as the
construction of additional or replacement wastewater treatment or disposal facilities. Construction of any
wastewater treatment facilities will require issuance of an Authorization to Construct from this Division.
Failure to abide by the requirements contained in this Certificate of Coverage and respective general permit may
subject the. Permittee to an enforcement action by the Division of Environmental Management in accordance with
North Carolina General Statute 143-215:6A to 143-215.6C. Please note that the general permit does require
monitoring in accordance with federal law. The monitoring data is required to be submitted to the Division no later
than January 31 for the previous year in which sampling was required to be performed.

responsible for the reissuance of the general permit and at such time, you will be notified of the procedures to
follow to continue coverage under the reissued permit. Unless you fail to follow the procedures for continued
coverage; you will continue to be permitted to discharge in accordance with the attached general permit.
The issuance of this Certificate of Coverage does not preclude the Permittee from complying with any and all
statutes; rules,. regulations, or ordinances which may be required by the Division of Environmental Management

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Rowan Mining Company, is requesting the
issuance of a permit which would allow the discharge of treated
wastewater produced from pit dewatering. The mining operation
consists solely of removing sections of granite from the natural
deposit and carrying them to the storage area with no washing,
finishing or additional processing. Rainfall and runoff are the
sole contributors to the accumulation of water in the pit..
The proposed discharge is into a roadside ditch that parallels
SR 2319. A condition may need to be included in the permit that
states if at any time the discharge creates a problem then plans
should be made immediately to correct, remove or _relocate the
discharge, including requesting any appropriate Permit
modifications.
Provided that.the settling pond can provide adequate storage
and settling then this Office has no objections to the issuance of
the permit.
It is recommended that the permit be issued -to include any
monitoring deemed necessary by the Technical Review Group.

Rowan Mining Company is proposing to begin mining operations at
the location shown on the attached map. Other pits exist in the area
due to previous mining operations.
The mining operation at this site will involve removing sections
of granite from the natural deposit and placing them on flatbed trucks
for shipment. The stone is taken directly from the natural deposit to
the storage area with no washing, finishing or additional processing.
The mining process leaves depressions in the stone formation as
sections of granite are removed. These pits fill with water which
collected in the pits is due to surface runoff from surrounding areas,
or from naturally occurring underground springs.
The area immediately adjacent to the quarry pit is part of the
granite formation consisting mostly of bare stone with some areas of
soil and sparce vegetation. The remainder of the area surrounding
the quarry is wooded.
Surface runoff from these areas will contain small amounts of
silt and rock chips. After a heavy rainfall, this runoff will be
pumped out of the pit and discharged into a silt basin located below
the pit. The silt will be retained in the silt basin allowing the
water to be cleanly discharged off site.

PROTECTED PLANS TO REDUCE THE VOLUME OF DISCHARGE WATER:
The owner plans to reduce the volume of discharge water by installing
a diversion ditch above the quarry pit.. This ditch will intercept
surface runoff before it reaches the pit and divert it away from the
area. This will reduce the volume of water that must be discharged
from the pit.
PROJECTED PLANS TO REDUCE THE EMISSION OF AIR CONTAMINANTS:
The owner plans to use slot drillers in the mining process. This
system uses drills which are driven into the rock to separate in-
dividual pieces for removal. These drills are equipped with dust
collectors designed to reduce air emissions.
