Engineering Alternatives Analysis (EAA)
to Evaluate Waste Disposal Alternatives for
BOILER BLOW DOWN for
PURINA MILLS, INC.
Prior to issuing an NPDES discharge permit, North Carolina's Division of Water Quality requires all
NPDES permit applicants to evaluate and establish their discharge alternatives by performing a
comprehensive Engineering Alternatives Analysis (EAA). It is the Division's mandate that an
applicant document, from all reasonable cost-effective options, the most environmentally sound waste
disposal alternative.
The Division of Water Quality (the Division) implemented the federally -delegated NPDES permit
program in response to the federal Clean Water Act of 1972, conscious of the specific goal "...to
eliminate all surface water point -source discharges by...1985." While the Division has yet to achieve
this goal, it continues to strive toward it by requiring individuals or organizations to complete an EAA
when applying for a new permit or expanding an existing NPDES permit under Title 15A NCAC
2H.0105 (c) (2).
I. GENERAL INFORMATION
A. Basic Identification of the Project
• Facility name: Purina Mills, Inc.
■ County: Iredell
■ Facility address: 173 McNess Road, Statesville, NC 28677
■ Facility telephone number: 704-924-5111
• EAA preparer's name: Gerald V. Grant, P.E.
• EAA preparer's mailing address and telephone number:
P. O. Box 268, Statesville, NC 28687-0268
704-872-3136
B. Detailed description of the project requiring wastewater disposal.
Animal feed is the leading agri-business sector in American agriculture today. Purina Mills, LLC
is clearly the U. S. leader in animal nutrition products, research and innovation, and is the largest
feed manufacturer in the country. Purina Mills products are identified by the checkerboard logo
and the Chow brand of feed. The company produces a complete line of commercial animal
products, as well as a line of horse, companion animal and specialty animal products, under
numerous, well-known brand names including Omolene, Equine Senior, Lean Generation, Impact,
Ultimate EXT and Layena. Strict Purina requirements for milling, formulation, packaging,
shipping and handling are closely adhered to, resulting in the delivery to the customer of products
which Purina has always guaranteed to meet the highest standards in the industry. The Statesville
plant produces most ol• all of these products. The Statesville plant was constructed in 1995 and
1996. The Statesville plant is under the management of Mr. Fred Hardison, Plant Manager. The
boiler system is managed by Mr. Wayne Whitney, Maintenance Supervisor. Water is supplied to
the plant site by Iredell Water Corporation with an 8 inch diameter PVC C-900 water main in
McNess Road, SR 2361.
Page 1 of 8
Engineering Alternatives Analysis; June 9, 2000

The boiler system is used to heat the feed products to aid in the pellet forming process. The boiler
steam system is a closed system without any designed steam losses, however, unintentional,
nominal steam losses do occur. The wastewater stream is the boiler blow down water. Please find
enclosed in the application package the water analysis report as well as the Material Safety Data
Sheets and Product Bulletins for the chemical additives used in the boiler blow down water. Also
enclosed with the application package are the analytical test results of the wastewater stream from
July 14, 2004. The tests measure alkalinity, COD, PH, TDS, temperature, and TSS. The original
flow determination that was used in 1995 was 1,200 gallons per day and was based on a similar
facility in Wilson, North Carolina. The boiler make-up water, which includes the boiler blow
down water, is metered at the Statesville plant and I have enclosed a boiler make-up water usage
study performed by CHEMGARD, INC. from July 13, 1999, until January 3, 2001. The study
illustrates that the make-up water is consistently less than the design flow of 1,200 gallons per day.
The North Carolina Department of Transportation wishes to design, permit, and supervise the
installation of the relocation of the nitrification fields for Purina Mills, Inc. that are being
displaced by the construction of the new United States Highway 70. The North Carolina
Department of Transportation will award the contract for the relocation of U. S. Highway 70 in
October 2004, and wishes to have the nitrification fields for Purina relocated prior to the
contractor beginning the roadway work. Therefore, your assistance in expediting the permitting
process will be of tremendous benefit to the Department of Transportation and the taxpayers of
North Carolina. .The proposed revision is to relocate the existing nitrification field for system
"B", the domestic wastewater system, and replace nitrification system "A", the boiler blow down
system, with a discharge in accordance with GENERAL PERMIT NO. NCG500000 under the
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) that have been
taken within the new right of way for United States Highway 70 relocation by the North Carolina
Department of Transportation. The plans illustrate relocating the nitrification field to the
southern end of Purina's property at Old Well House Road, SR 2593, and maintaining the
existing repair area for systems "A" as well as the installation of a detention basin with aeration
for discharge system "B".
C. The existing 3,000 gallon septic tank, the existing 1,500 gallon pump tank, existing pumps,
valves, controls, gravity collection pipe, and force main pipe will continue to be used as
illustrated on the attached plans and specifications. These components have performed
adequately for the past eight (8) years.
D. The project will not be constructed in phases.
II. EVALUATE DISPOSAL ALTERNATIVES
The Engineering Alternatives Analysis should evaluate any and all disposal alternatives to
include, at a minimum, the following:
• Connecting to a Publicly Owned Treatment Works (POTW)
• Connecting to a privately owned treatment works
• Feasibility of individual subsurface systems
■ Feasibility of community subsurface systems
Page 2 of 8
Engineering Alternatives Analysis; June 9, 2000

• Drip irrigating - both surface & subsurface
• Spray irrigating
• Reuse
• Surface water discharge through the NPDES program
• Any possible combination of the above options
A. Connecting to a Sewer -Collection System (served by a municipality or other entity holding a
valid NPDES or Non -Discharge Permit).
1. Existing Sewerage System: Indicate the distance to any existing sewer line within a five -
mile radius (extension of radius should be considered if cost effective for project size).
*NOTE: All connection options should include an evaluation of both a gravity line as well
as a force main with pump station(s).
(a) Provide a description of sewer facilities and resources necessary to connect to the
receiving wastewater treatment plant.
Purina Mills, Inc. can connect to the City of Statesville sanitary sewer system by way of a
pump station and force main. A public gravity collection system will be used to direct flow
from the site improvements to the pump station. The subject sewer improvements
represent a $253,500.00 investment by Purina Mills, Inc. The connection to the City's
system will be at an existing manhole in John Long Road, SR 2313. Purina Mills, Inc.
understands that they must obtain the necessary easements and encroachment agreements,
that they must bear all the costs for materials and installation, that they must execute an
Extra-Territoral Wastewater Discharge Agreement with the City of Statesville, and that
they must pay any required system development fee and a tap connection fee. Furthermore,
the City of Statesville may require voluntary satellite annexation thereby subjecting Purina
Mills, Inc. to City taxes.
(b) Provide a preliminary indication of flow acceptance from local municipal or
private WWTPs under consideration. If a municipal or private WWTP cannot
accept the wastewater, please explain.
The City of Statesville Public Works Director has agreed to present a request for
the sewer connection to the City Council however, the final authorization can only
be granted by the City Council.
(c) Attach a topographic map or a scaled site drawing showing the physical route of
this alternative.
Please find proposed plan and profile drawings for the subject sewer extension.
1
(d) Perform a Present -Value -of -Costs Analysis for this alternative as outlined in
Appendix A of this document. Investigate cost -sharing options with other
potential users.
Page 3 of 8
Engineering Alternatives Analysis; June 9, 2000

The proposed sewer extension and connection to the City of Statesville was
presented to the industrial neighbors of Purina Mills, Inc. including Southern
-States Corp., R. a Monroe, Inc., CDSF, Ltd., and American Stainless Tubing.
Inc. However, these entities did not express an interest in the subject connection
at this time.
2. Planned Sewerage System: Determine if an area -wide sewerage system, within a five mile
radius, is projected to be available within the next five years that could receive waste from
your project. Determine, from the appropriate authority, an availability date and flow
acceptance projection. Identify your public utility or private management -group contact
person that assisted you with this determination.
The City of Statesville already has a sewerage system within a five mile radius.
B. Land -Based Disposal (Installing nitrification systems, low pressure pipe systems, drip
irrigation, mound systems, and spray irrigation systems).
1. Does your organization currently own land that is available and suitable for a subsurface
system? Yes.
(a) Provide a description of the necessary facilities and resources including a site plan
indicating the proposed layout.
The subject boiler blow down water for Purina Mills, Inc. has been disposed
the past eight years by a nitrification system that consist of a septic tank,
a pump tank, a force main, a pressure manifold, and nitrification lines.
The nitrification system is being displaced by the relocation of U. S. Highway 70
by the North Carolina Department of Transportation.
(b) Provide soil analyses (see Appendix B of this document).
Soil analysis by the Iredell County Health Department and Soil & Environmental
Consultants, PA are attached. It is the opinion of Mr. Joseph Pearce, P.E.
Environmental Engineer II for the ON -SITE WASTEWATER SECTION in the
Division of Environmental Health, that the subject soils are not capable of
neutralizing the high alkalinity of the wastewater. Therefore, Mr. Pearce
suggested that the applicant apply for GENERAL PERMIT NO. NCG500000.
(c) Provide calculations used to determine the proposed land disposal capacity. Base
these calculations on design and loading -rate characteristics according to
appropriate regulations.
Calculations Tre attached.
(d) If there is insufficient usable land at the site, address why. Describe how you
would modify the plans (reducing the number of units or reduce the design flow,
etc.) to allow for inadequate disposal caused by unusable land.
Sufficient land is available for adequate nitrification disposal.
Page 4 of 8
Engineering Alternatives Analysis; June 9, 2000

(e) Perform a Present -Value -of -Costs Analysis for this alternative as outlined in
Appendix A of this document.
2. If there is insufficient land at the proposed site, determine if any additional land could be
acquired. Document land availability in your area. If adjacent land could be acquired,
evaluate according to item B (1). If adjacent land is unavailable, provide documentation from
the owner stating such.
Sufficient land is available for adequate nitrification disposal.
3. NOTE: Subsurface disposal systems require a 100% reserve area. Surface disposal systems
must be capable of treating waste to secondary limits including disinfection.
C. Wastewater Reuse Evaluate reusing all or a portion of the wastewater generated on -site.
An evaluation was performed to use the boiler blow down water in the animal feed production,
however the U. S. Food and Drug Administration disapproved the use of the boiler blow down
water in the feed production process.
D. Surface Water Discharge (discharge to a flowing stream - defined as having positive 7Q10
and 30Q2 flows).
1. The U.S Geological Survey (USGS) should be consulted to obtain receiving -stream flow
information. This information should be submitted in conjunction with treatment plant
design. For flow information contact Mr. Curtis Weaver at [phone].
2. Proposed treatment systems should compare discharge both with and without tertiary
filtration, assuming a weekly sampling regime.
3. Describe the proposed discharge facilities. Include a schematic diagram of the major
components and a site plan with outfall line(s). All discharge systems must meet design
criteria outlined in the Division's Authorization to Construct process.
The subject boiler blow down water shall be collected in septic tank for solids settling, then
to a pump tank for PH monitoring and sulfuric acid injection to lower PH, then to a detention
basin with aeration for cooling, then to an existing storm drainage system that discharges to
an unnamed tributary of Third Creek. Third Creek is a Class "C" stream from its source to a
point 0.7 mile upstream of Rowan County SR 1970 and the Classification Index No. is
12-108-20-4-(0.5). -=
4. Document the availability of required land and/or easement agreements.
Sufficient land is available for discharge.
5. Perform a Present -Value -of -Costs Analysis for this alternative as outlined in Appendix A of
this document.

Subject: Low -flow characteristics for unnamed tributary to Third Creek in Iredell County
Mr. Grant,
In response to your inquiry about the low -flow characteristics for an
unnamed tributary to Third Creek in Iredell County, the following
information is provided:
No previously determined estimates of low -flow discharges were found for
your site of interest (as indicated on the fax location map). In the
absence of site -specific data on the tributary that could be used for an
analysis, low -flow discharges for ungaged locations are estimated by
assessing the low -flow yields (expressed as flow per square mile of
drainage area, or cfsm) at nearby sites where low -flow characteristics have
been determined.
Low -flow characteristics for two sites on nearby Third Creek (station id's
02119431 and 02119435) suggest that 7Q10 and 30Q2 low -flow yields
applicable to this immediate area are about 0.25 cfsm and 0.50 cfsm,
respectively.
However, examination of your site's location on a topographical map
indicates the point of interest is very near the ridge line between streams
that drain to Fourth Creek (to the north) and Third Creek (to the south).
A "quick-n-dirty" drainage -area delineation above your site of interest
indicates that a drainage -area value would be less than 0.02 sqmi. To get
the low -flow discharge estimates, the drainage area is multiplied by the
low -flow yields. In this case; however, the small drainage area applied to
the yields results in flow estimates that are practically zero flow.
Putting together the above pieces of information leads to a conclusion that
appropriate estimates for the 7Q10 and 30Q2 low -flow discharges for your
site of interest are both zero flow.
Hope this information is helpful.
Thank you.
Curtis Weaver

Appendix A
Present -Value -of -Costs Analysis
The Present -Value -of -Costs Analysis (PVCA) is meant to evaluate all costs associated with a particular
disposal alternative over the life of the project. Prior to performing a PVCA for any of the alternatives,
all costs must be identified. The PVCA should include all monetary costs associated with construction,
startup and operation of a facility. Costs should include, but not be limited to, the following:
Capital Costs
• Land acquisition costs
• Equipment costs
• Labor costs
• Installation costs
• Design costs
Recurring Costs
• Operation and maintenance costs (with replacement costs)
• Laboratory costs assuming a weekly monitoring regime for discharge systems
and a monthly regime for non -discharge systems
• Operator and support staff costs
• Residual disposal costs
• Connection and subsequent user fees
• Permit and compliance fees
• Utility costs (power, water, etc.)
Opportunity Costs
NOTE: The applicant shall reference all cost information. If vender quotes have
been received for treatment units or other components, the applicant shall
include these in the document.
Page 6 of 8
Engineering AIternatives Analysis; June 9, 2000

Calculating Present Value of Costs
Costs incurred in different time 'periods must be converted to a common time before they can be
accurately combined or compared. Performing this calculation is known as "computing the present
value," or "discounting" the costs. Present value is also sometimes called "present discounted value" or
"present worth."
The applicant shall compute the present value of all cost estimates prepared under this evaluation
guidance using the following standard formula:
Where:
PV=C +L
C
,, i_i (1 + 01
PV = Present value of costs.
Co = Costs incurred in the present year.
Ct = Costs incurred in time t.
t = Time period after the present year (The present year is t = 0)
n = Ending year of the life of the facility.
r = Discount rate. For these calculations, the applicant shall use an interest rate
quoted by the lending institution. The loan interest rate quote shall be
provided with this analysis.
However, if costs are the same in every time period from year one through year n (i.e., Ct = C, a
constant for t = 1,2,..., n), then the formula reduces to:
PV =C„ +C (1+r) I'1
r(1+r)
In this case, the present value may also be retrieved from a table containing the present value of annuities
(an annuity is a constant amount payable in each year for a certain number of years). Such tables are
available from financial institutions.

Re: Soil/Site Evaluation for Purina Mills, LLC Property located off Old Well House Rd in
Iredell County, NC
Dear Mr. Grant:
Soil & Environmental Consultants, PA. (S&EC) performed a preliminary soil and site evaluation
on the above referenced tract. This was performed at your request as part of the preliminary
planning process in order to determine areas of soil that have potential for subsurface wastewater
disposal. The existing septic system is proposed to be taken by NCDOT for a proposed US
Highway 70 project. The purpose of our evaluation was to determine if the area proposed for the
new system was potentially usable. The system is to have a daily flow of less than 3,000
gallons/day (gpd). '
S&EC traversed the property and observed landforms (slope, drainage patterns, past use, etc.) as
well as soil conditions (depth, texture, structure, seasonal wetness, restrictive horizons, etc.)
through the use of hand auger borings. The site was evaluated during dry soil conditions. From
these observations, an evaluation of the site, relative to subsurface disposal of wastewater, was
developed. Soil areas were estimated in the field. The soil/site evaluation criteria used is that
contained in 15 A NCAC 18A .1900 "Laws and Rules for Sewage Treatment and Disposal
Systems".
FINDINGS
The upland soils on this tract are similar to the Cecil and Pacolet soil series. The Cecil and
Pacolet soil series have a clay texture subsoil. These soils are typically greater than 36 inches
deep to prohibitive soil characteristics and can be usable for subsurface septic systems. None of
the area evaluated was unusable due to soil depth.
The accompanying map shows the approximate location of the soil descriptions I made and the
location of descriptions by Brady Freeman of the Iredell County Health Department. The soils
within the proposed system area are at least 36 inches deep to prohibitive soil characteristics and
these areas have potential for a conventional septic system or a modified conventional -(shallow
placed lines with no fill required over the disposal area)
GENERAL WASTEV 1ATER CONSIDERATIONS
Once potentially useable areas are locatedthrough vertical borings, the next consideration is the
horizontal extent of those areas. The size and configuration of the useable soil area dictate the
utility of that area. The size of a subsurface disposal field is determined by: 1) the design flow
from the source, and 2) the long term acceptance rate (LTAR) of the soil (based on the hydraulic
conductivity of the soil, a function of the soil's texture, mineralogv. structure, porosity, etc.). The

configuration must he such that an efficient layout of disposal lines (on contour) is possible. An
additional consideration is the required setbacks for the system from various elements such as
wells (100'), streams and ponds (50') or more (depending on watershed regulations), property
lines (10'), top of embankment (15'), watershed buffers, etc. (see Attachment 1).
The utility of a potential useable soil area for a subsurface system is most accurately determined
by an on -ground layout of the proposed system. You have already provided drawings showing
the layout of the proposed system. Based on Laws and Rules for Sewage Treatment and Disposal
Systems for North Carolina, the clay soils on site have a range for the longterm acceptance rate
(LTAR) between 0.1 and 0.4 gpd/ft2 for conventional septic systems (.1955). With the soils on
site I would recommend a LTAR of 0.3 gpd/ftand trench depth of 24 inches. The health
department will determine the ultimate LTAR after their evaluation.
The wastewater for this site is from a nondomestic source. However, soil samples were not sent
to a lab to get soil chemical data for this site. This was performed when the system was initially
permitted. You provided information stating the main factors with this wastewater that differ
from domestic wastewater are high pH and high temperature. Both of these factors are addressed
in the design of the system. This was also discussed with a representative with the state and they
did not believe soil chemical data would be necessary.
This report discusses the general location of potentially useable soils for on -site subsurface
wastewater disposal and, of course, does not constitute or imply any approval or permit as needed
by the client from the local heath department. S&EC is a professional consulting firm That
specializes in the delineation of soil areas for wastewater disposal and the layout and design of
wastewater treatment systems. As a professional consulting firm, S&EC is hired for its
professional opinion in these matters. The rules governing wastewater treatment (interpreted and
governed by local and state agencies) are evolving constantly, and in many cases, affected by the
opinions of individuals employed by these governing agencies. Because of this, S&EC cannot
guarantee that areas delineated and/or systems designed will be permitted by the governing
agencies. As always, S&EC recommends that anyone making financial commitments on a tract
be fully aware of individual permit requirements on that tract prior to filial action. •
Soil & Environmental Consultants, PA. is pleased to be of service in this matter and we look
forward to assisting in any site analysis needs you may have in the future. Please feel free to call
with any questions or comments.
Sincerely,
Steven M. Price
