Subject: Distribution and Marketing
Permit No. WQ0006497
We have received the above referenced distribution and marketing permit
and appreciate all of your efforts and. cooperation in processing it. We
have several questions and comments pertaining to the requirements stated
in the permit. As soon as convenient, we would appreciate the opportunity
to discuss them in more detail with you and negotiate changes that are
acceptable to both parties. As you recommended, we are taking this
approach rather than going through the formal adjudication process.
Several of our questions and concerns are briefly described as follows:
Performance Standards, Page 2
Item No. 8: Since the product meets PFRP requirements and is
therefore pasteurized, what is the reason for this condition?
Operation & Maintenance Requirements, Page 2
Item No,3: The reference to "composting" should be deleted and
replaced with "alkaline stabilized sludge."
Item No. 4: What is the reason for requiring that the stabilized
sludge be stored in a silo prior to being loaded into trucks for
distribution? As indicated on our process schematic, the
product is loaded directly into the truck from a belt conveyor -
no silo is currently used. There is, however, a silo/hopper for
storage of dewatered sludge cake. This unit was existing before
the construction of the al kaline.stabilization facility and is
used when land application of sludge is desired. It is important
that this item be changed as there is no. silo currently on-line
for product storage. Additionally, the product directly from
the mixer is of a consistency that is not readily conducive to
silo storage. The material would likely cling to the sides of

TELEPHONE MEMORANDUM
DATE: May 11, 1992
CLIENT: CMUD
PROJECT: Advanced Alkaline Stabilization
TO: Mike Parker
COMPANY: NC DEM Mooresville Regional Office
PHONE NO.: [phone]
RECORDED BY: Pam Racey
- I explained to Mike Parker that CMUD and Black & Veetch,
and I met with Carolyn McCaskill and Dennis Ramsey of DEM
on Monday, May 4, 1992 to discuss alternatives for using
advanced alkaline stabilized material.
- The primary alternative discussed was use as a liming
agent. It was decided that CMUD would apply for a
distribution and marketing permit for the material on a
fast track. In the meantime, CMUD could utilize the
material on permitted sites alone or in conjunction with PSRP
sludge. I asked Ms. McCaskill whether temporary stockpiling
on farm sites would be allowed and whether the farmers
could spread it on their own. She had no problem with
farmers spreading it, as long as the regulations were
followed. She referred me to Condition I 12 of permit
WQ0000057 which allows for temporary stockpiling as long
as prior approval is obtained from DEM. She asked me to
check with the regional office for that approval.
- I asked Mike if we could deliver alkaline stabilized
product to a permitted farm and stockpile temporarily.
I stated that we would strive to have the material spread
within a week, but in no case would it be longer than two
weeks. He agreed to allow this provided that Bio Gro was
involved in selecting an appropriate stockpiling site
(i.e. away from surface water, property lines, etc.). In
addition, he asked that hay bales be placed on the down
slope side of the stockpile to.prevent any runoff, if
warranted.

Mecklenburg County who administers the AQ program in this
area. The applicant should provide the Division with
documentation that the County has been notified of the
existance of these facilities and appropriate Permits (if
necessary) obtained. There are no hazardous materials
utilized at this facility. GW comments should be obtained
prior to the issuance of this Permit.
PART IV - EVALUATION AND RECOMMENDATIONS
The Charlotte -Mecklenburg Utility Department (CMUD) requests
approval to produce and distribute an alkaline stabilized sludge
product (AASP) from processing facilities currently located at
the McAlpine Creek WWTP. The production of the AASP began a few
months ago with the AASP being used as a supplement for final
cover at the county landfill. Due to delays experienced by the
landfill in obtaining cover material, CMUD requests approval to
distribute the AASP for public and commercial uses.
Our review indicates that the AASP should be acceptable for
public distribution provided PFRP requirements are met. There is
some concern regarding runoff should on -site stockpiling of AASP
be necessary. it is suggested that a minimum buffer distances of
100 feet from a well, surface waters and/or a wet -weather
drainage feature be used for AASP stockpiling.

A meeting was held in Raleigh, NC on May 4, 1992 at 10:00 a.m. with
NCDEHNR to discuss other options for using the artificial soil product.
1. Ms. Mendenhall explained that the one of the goals of the CMUD
Demonstration Project is to evaluate the suitability of alkaline
stabilized sludge as landfill cover material. This project is being.
conducted in conjunction with the Water Resources Research Institute
(WRRI) and the North Carolina State University. WRRI's research
investigation is ongoing at this time; although some preliminary
results have been received. The time frame permitted by the Solid
Waste Division for use of artificial soil at the Harrisburg Road
landfill was based on actual landfill operations: daily cover
operations until April 1, 1992 and final cover operations from April
1 until October 1, 1992. However, use of the artificial soil for
final cover operations is currently stalled as the Harrisburg Road
landfill is awaiting soil for final cover operations. At this time,
it is uncertain when the landfill will begin final operations.'
2. Another- objective of the Demonstration Project was to evaluate
opportunities for reuse other than landfill cover material, i.e., an
agricultural liming agent. Because the artificial soil product is
a Class A (PFRP) product with fertilizer and liming value, it could
be considered for distribution and marketing..
3. Ms. Psaris asked Mr. Ramsey what his primary concerns were with the
use of this material and if a demonstration could be initiated to
develop data to support the u'se of this material. Considering that
more municipalities may be investigating alkaline stabilization as
a possible sludge management alternative, a demonstration could

4. Considering that the alkaline stabilized material would be lime
limited and not nutrient or metal limited, Mr. Ramsey said that there
was no problem in using the material right away as an agricultural
liming agent for the currently permitted land base. This application
would be in addition to the PSRP sludge currently applied. He also
commented that he had no problem with selling the material as aglime
if using the current land base.
5. Mr. Ramsey and Ms. McCaskill indicated that a Distribution and
Marketing permit should be obtained for use of the material. They
both felt that the alkaline stabilized material had many potential
uses like compost and could be marketed accordingly. Consequently,
the same application form and process for a compost distribution and
marketing permit should be used for the alkaline stabilized material.
Because of the time frame for the existing Demonstration Project and
the equipment leased to produce the product, there was concern that
there would be insufficient time to obtain permit approval. Ms.
Psaris suggested that the existing land application permit that CMUD
holds might be modified to allow for the distribution and marketing
of the this material. Mr. Ramsey noted that a permit modification
would require the same amount of time for review and approval as a
new permit application. Ms'. McCaskill assured that she would assist
as much as possible to process the application.
6. Ms. McCaskill recommended sending the following information part of
the permit application:
• Process monitoring and recordkeeping logs
• Manufacturer's information for the blender and condenser
• North Carolina Engineer Sealed process schematic
• Product information to be given to potential users
7. Potential uses for the alkaline stabilized material were discussed.
These included land reclamation, turf farms, DOT applications,
commercial aglime, and possibly nurseries.
8. Ms. Racey asked if the material could be stockpiled on the farm land
under the existing permit with subsequent spreading by the farmer.

APPLICATION FOR DISTRIBUTION & MARKETING PERMIT
I. Introduction
A. Background
As part of Charlotte-Mecklenburg's residuals management program, a
demonstration project has been implemented at the McAlpine Creek Wastewater
Management Facility (WWMF). An advanced alkaline stabilization project was
selected in an effort to diversify CMUD's residual management program. Although
alkaline stabilization of wastewater residuals has been used for many years, there has
recently been an emergence of advanced alkaline stabilization technologies that
achieve enhanced degrees of pathogen destruction. These processes satisfy EPA's
criteria for a "Process to Further Reduce Pathogens" (PFRP). The resultant product
(Advanced Alkaline Stabilized Product, or AASP) from these processes typically
resembles a soil -like material and has several uses (i.e., landfill cover material,
agricultural liming agent, etc.).
To date, the product from CMUD's demonstration project has been beneficially
utilized as daily landfill cover material at the Harrisburg Road Landfill in Charlotte,
North Carolina. Currently, the Water Resources Research Institute (WRRI) and the
North Carolina State University are working in conjunction with CMUD to evaluate
the suitability of using the advanced alkaline stabilized material as landfill cover
material and its effects on landfill conditions.
Objectives of the demonstration project are as follows:
• To produce a product that meets "Process to Further Reduce Pathogens" or
PFRP requirements. Producing a PFRP product (federal Class A) allows
more unrestricted distribution of the product due to the higher degree of
pathogen destruction.
• To alter the physical characteristics of the wastewater residuals. Physical
characteristics that may be altered include the solids content and the
granularity of the material, which improve the storability and handling of the
end -product.
• To process the material in a manner that minimizes odor production.
• To assess the suitability of the AASP as daily and final landfill cover material.
Operations at the landfill will be defined and documented.

• To evaluate the potential for using alternative alkaline materials such as lime
kiln dust and quicklime blends, fly ash, etc.
• To beneficially utilize the material in end -uses other than landfill cover, such
as an agricultural liming agent, DOT applications, and commercial uses.
Several other counties in the United States have successfully requested and
instituted distribution and marketing permits for advanced alkaline stabilized sludge.
Kent County, Delaware, for example, recently implemented advanced alkaline
stabilization with the product to be distributed and marketed to area farmers as a
soil enricher for crops. The program has significantly reduced the amount of sludge
.currently being landfilled.
B. Request for Distribution and Marketing of RASP
In the state of North Carolina, no specific permit exists for the distribution and
marketing (D&M) permit for AASP. Because this material has several end -uses
similar to a compost product and is a high quality material (PFRP), Mr. Dennis
Ramsey and Ms. Carolyn McCaskill, NCDEHNR, recommended that the permit
application for D&M of AASP follow the same guidelines as the compost permit
application. It is the aim of this application to demonstrate for approval, a D&M
permit for AASP. Included in this submittal are the following:
• Land Application of Residual Solids Permit for McAlpine Creek WWMF.
• Process and facilities description including a site plan, sealed process
schematic, and manufacturer information for the blender and spray
condenser.
• Process monitoring and recordkeeping to show that the AASP meets PFRP
criteria (i.e., 70 °C for 30 minutes).
• Verification that the AASP and dewatered sludge cake are non -hazardous
(TCLP results, ignitability, corrosivity, etc.). Other characteristic data are also
provided for both the dewatered cake and the alkaline stabilized material.
• Information on the product end -uses, recommended application rates, and
buffer requirements, which will be provided to all recipients of the AASP.
W

II. Process and Facilities Description
A. Site Description
The alkaline stabilization facility is located at the McAlpine Creek WWMF, which
is situated on a 400-acre parcel of land to the east of U.S. Route 521 in Pineville,
North Carolina. A general site plan to scale, including highways, fences and process
buildings is attached. The covered alkaline stabilization facility is located on the
northwest side of the Sludge Thickening and Dewatering Building as presented in the
enlarged version of the site plan.
As shown in the schematic, also attached, the primary components of the
advanced alkaline stabilization process consist of the sludge conveying system,
sludge/alkaline material mixing, odor control, and truck loading. These areas are all
covered (total gross area 3,200 sq. ft.). A concrete pad has been provided for the
process equipment and is slightly sloped for adequate drainage, which is returned to
the headworks of the plant. Traffic flow resulting from alkaline material delivery and
product transportation follows Road H around the Sludge Thickening and
Dewatering Building and out the main entrance of McAlpine. Truck traffic has been
carefully integrated with other plant operations to avoid potential congestion and
accidents.
B. Process Description
The McAlpine Creek WWMF is a secondary treatment plant which produces
anaerobically digested, centrifugally dewatered sludge cake. Polymer is added prior
to dewatering. The dewatered sludge is conveyed via screw conveyor to a receiving
hopper. There is a manual slide gate on the screw conveyor that allows the
dewatered sludge to drop into the receiving hopper. Because the capacity of the
receiving hopper is only 300 cubic feet, there is limited storage capability between the
centrifuges and the stabilization system. As a result, the advanced alkaline
stabilization process operates on-line with the dewatering operations. When land
application of the sludge is desired, the slide gate is closed and the alkaline
stabilization facility is bypassed. Sludge is then conveyed to a storage silo prior to
truck loading silo and subsequent land application.
As shown in the attached process schematic, the principal system components of
the advanced alkaline stabilization process include: a sludge receiving hopper, feed
screw and belt conveyors, sludge plow blender, spray condenser, alkaline material
storage and feed system, instrumentation and control system, and truck outloading
facility. Additional details about the equipment are provided in the table below.
Manufacturer information for the blender and the spray condenser are attached to
the back of this submittal.

The advanced alkaline stabilization process has been designed based on the
following criteria:
• 20% total solids dewatered sludge cake;
• 2 - 5 dry tons per hour;
• Facility operating 12 hours per day, 6 days per week.
Sludge production values have varied from 12 to 30 dry tons per day processed
depending on whether one or two centrifuges are operating. Total solids content of
the dewatered cake have also ranged from 15% to 20%. Because of the flexibility
of the advanced alkaline stabilization process, the alkaline material dosage can be
varied very easily to maintain consistent end -product solids concentrations and
characteristics (e.g., no sludge balls). The RASP resembles a soil -like material and
has solids concentration of 50% or more.
The alkaline material is pneumatically conveyed from a truck into a storage silo.
The bulk storage silo is equipped with a dust collection system for dust control and
vibrators to facilitate unloading. The alkaline additive is metered with a volumetric
screw feeder and conveyed to the plow blender where it is mixed with the dewatered
sludge cake. After mixing, the material travels along a belt conveyor and unloaded
into a truck. Once the truck is filled, the material will be stockpiled if there is a lag
time between production and distribution.
Through the addition of the alkaline additive (e.g., quicklime, lime kiln dust, etc.),
chemical reactions occur that increase the solids content of the mix. This increase
in solids is due to the cumulative consequence of the addition of solids, the chemical
binding and evaporation of the water in the sludge. The use of alkaline material
produces a reaction resulting in temperature increases within a matter of minutes.
Thorough mixing of the sludge and alkaline material is extremely important to
achieve the target solids content, pathogen destruction, and to minimize residual
odors in the final product. Water and off -gases during mixing are collected and
treated by a spray condenser. Water condensate will be returned to the wastewater
plant headworks for treatment creating a closed loop for the collection and treatment
of water and off -gases.
5

III. Monitoring and Process Control
A. Introduction
The importance of process and product monitoring cannot be overemphasized.
Process control parameters are monitored in order to optimize process performance
and to produce a consistent quality material. Several parameters of importance when
performing alkaline stabilization are the degree of pathogen kill, solids content, and
the concentrations of heavy metals in the resultant product. The pathogens in the
sludge are reduced to below detectable levels by the alkaline stabilization process and
is thus considered a PFRP (as defined by 40 CFR Part 257). To satisfy PFRP
criteria, a temperature of 70°C must be maintained for 30 minutes. In order to
demonstrate that PFRP criteria have been met, the temperature of the
sludge/alkaline material mixture is monitored and recorded.
B. Monitoring Forms
Daily monitoring is coordinated between CMUD and Bio Gro personnel to avoid
duplication of effort. CMUD staff are responsible for keeping a complete log of
daily. operations. A Lotus program is utilized which updates the daily logs into
weekly and then monthly totals. Examples of the monitoring forms are presented
and computer printouts are attached to the back of this submittal. Descriptions of
the parameters that are monitored and recorded on the Daily Monitoring Form are
given below.
General Conditions
General weather conditions have a potential impact on the process equipment
and operations.
a. Ambient Temperature. The air temperature is recorded at the beginning of
each operating day. If large variations in air temperature occur during operation,
they are also noted.
0

b. Wind Direction. The wind direction,. including significant changes in the
direction, is recorded during the operating period each day. If odor complaints occur,
the . wind direction, along with the other meteorological conditions, may help
determine the specific location of the odor/complainant and what can be done to
resolve the odor problem.
C. Precipitation. If precipitation occurs during the operation period, "Yes" is
circled on the Monitoring Form. Otherwise, "No."
d. Sky Conditions. One of the given sky conditions is indicated: clear, hazy,
overcast, or cloudy. If another description of the sky condition is more appropriate,
it is indicated so on the Monitoring Form.
2. Sludge Cake
The quality characteristics of the sludge to be stabilized are very important
factors that affect the advanced alkaline stabilization process and the quality of the
end -product. The amount and variability of the influent sludge will impact the
throughput of the facility. Variable or poor performance of the centrifuges resulting
in low solids concentrations significantly affects the chemical dosage requirements
necessary to produce a high -solids, PFRP product.
a. Centrifuge Feed Solids Concentration. An accurate feed solids percentage is
important for determining the mass of dry solids in the sludge to be alkaline
stabilized. The centrifuge feed solids concentration is recorded which may be
obtained from the McAlpine Creek WWMF Dewatering Operator.
b. Centrifuge Feed Rate. In order to determine the amount of sludge being fed
to the alkaline stabilization process, the feed rate to the centrifuges needs to recorded
(in gallons per minute, gpm). This information is obtained from the McAlpine Creek
WWMF Dewatering Operator. Large variations in the centrifuge feed rate are noted
in addition to the time of day that the feed rate was altered.
c. Centrifuge Input. One of the most important control variables during the
centrifuge operation, as already noted, is the feed rate to the centrifuge, both from
VA

a hydraulic and solids loading standpoint. The solids loading to the centrifuge is
determined and recorded using the following equation:
[ FR, gpm x 60 minlhr x 8.34 lblgal x FS, % ] x 100 = CI lbs/hr
Where: FR = Centrifuge Feed Rate, gpm
FS = Feed Solids, %
CI = Centrifuge Input, lbs/hr.
d. Cake and Centrate Solids Concentrations. Depending on the sludge
characteristics and composition, the cake may vary from a wet, sloppy mass to a
- relatively dry, firm solid mass. The target product solids concentration is 50 to 60%,
depending on the application. Under normal operating conditions utilizing polymers,
the centrate solids will constitute five to eight percent of the feed solids. These solids
are normally recycled to the head of the plant. The solids content of both the sludge
cake and centrate are determined using the Microwave Solids Analyzer (CEM AVC
80) located in the Sludge Thickening and Dewatering Building.
e. Percent Capture. The percent capture is determined using the following
equation:
100 x [ SCS x (FS - CS)] _ [ FS x (SCS - CS) ] = % Capture
Where: SCS = Sludge Cake Solids, %
FS = Feed Solids to Centrifuge, %
CS = Centrate Solids, %.
f. Centrifuge Output. The dry mass of sludge solids centrifuged is determined by
multiplying the centrifuge input by the percent capture. Note that percent capture
should be in the percentage form when multiplying (i.e., use,95 p ).
2. pH.
Because alkaline material addition to meet PFRP temperature requirements is
critical, the pH of the material is measured less frequently than temperature
immediately after mixing.
E'?

3. Temperature.
The length of time and temperature to which the sludge/alkaline additive mixture
is heated is critical to the effectiveness of the process for pathogen reduction. The
temperature of the AASP is measured on hourly grab samples. and continuously
monitored using temperature probe linked to a computer which logs the results over
time (see attached temperature computer log). If there are problems with the
computer system, the temperatures must be taken and recorded manually from the
digital reading on the temperature probe. The Computer Log or Manual
Temperature Monitoring Log is then attached to the Daily Monitoring Form.
4. Feed Rate.
The feed rate of alkaline reagent to. the blender is recorded (in lb/hr) since
alkaline material addition to meet PFRP temperature requirements is very important.
Enough alkaline material has to be added to raise the total solids to 50%, to raise the
pH above 12, and to raise the temperature above 70°C for at least 30 minutes.
5. Alkaline Material Dosage.
The percent alkaline material added to the sludge is determined using the
following equation:
X lb/hr x I ton/2, 000 lb x 1000 = Z %
Y wet tons/hr
Where: X = lime feed rate (lb/hr)
Y = sludge feed rate (wet tons/hr)
Z = percentage of alkaline material (%).
6. Product Appearance - Color.
The color of the AASP. Although the color will depend the solids content of the
product and the amount of alkaline material added, it should appear medium to light
brown.
7. Product Appearance - Particle Size.
Although not related to PFRP requirements, the AASP should have a uniform
granular texture bearing natural soil appearance with no "sludge balls" or large lumps.
9

E. Operations Daily Log
This section highlights some of the operation and maintenance issues pertaining
to the advancedalkaline stabilization process that are inspected and documented on
a regular basis. Consistent operating procedures are instrumental in producing a
consistent quality product. The advanced alkaline stabilization process requires
regular adjustments due to changing dewatered sludge characteristics.
Generation of Odors.
The addition of alkaline material to dewatered sludge increases the pH of the
mixture. Although this elevated pH helps to reduce biological action, thereby
reducing odors caused by putrefaction, the high pH also causes ammonia present in
the sludge to be converted to an anhydrous form which releases as a gas. A spray
condenser has been provided to treat the ammonia as it is released during the mixing
step and has proven to be effective.
2. Equipment.
The successful production of AASP depends on the reliability and performance
of the equipment and how it is operated. Routine inspection and servicing are
important elements in a preventive maintenance program. Motor fans, bearings,
shaft lip seals, and alkaline material feed components are inspected regularly and
cleaned or lubricated as necessary. Daily and weekly maintenance schedules are
followed to prevent excessive wear of equipment and downtime due to improper
maintenance.
3. Alkaline Material.
The type and dosages of the alkaline material(s) to be added to the sludge are
important as the quality of the additives must be consistent to ensure a consistent
quality end -product. The required dosage of these alkaline materials depends on the
sludge characteristics and was determined by bench -scale and pilot testing. Bench -
scale testing of McAlpine sludge mixed with various alkaline materials has been
performed.
a. Type. Various alkaline materials have been used for stabilization such as
quicklime (pebble and pulverized), lime kiln dust, cement kiln dust, Portland cement.
10

Each of these alkaline materials have different characteristics which will affect the
dosage required to achieve a granular, PFRP product.
b. Percent CaO. The calcium oxide, CaO, in the alkaline additive chemically reacts
with the water in the sludge to produce heat. Quicklime typically has a CaO content
of 90 to 95% and reacts very quickly with water to form caustic hydrated lime, or
Ca(OH)Z. Other alkaline materials, such as cement or lime kiln dust, have CaO
concentrations lower than quicklime. The hydrated lime causes the pH of the
sludge/chemical mixture to increase as well as the temperature. The heat rise
associated with the chemical reaction also evaporates water from the mixture, thus
increasing the solids content. As previously discussed, the alkaline material -sludge
reaction will produce heat quicker when complete, thorough mixing is achieved.

TCLP analyses for the anaerobically digested sludge and AASP were completed
by PAR Laboratories of Charlotte, North Carolina on February 19,1991 and March
31,1992 respectively. Copies of the TCLP results are attached.
B. Additional Testing
In addition, the sludge and AASP were analyzed for pH, corrosivity, reactivity,
flash point, and ignitability, in addition to metals and other parameters by PAR
laboratories. Both were determined to be non -corrosive, non -reactive and non -
ignitable and flash point was found to be greater than 200 degrees Fahrenheit. The
sludge pH value was 7.1, almost neutral on the pH scale. The pH of the AASP
measured 12.1 which will result in an excellent agricultural liming agent for pH
adjustment and soil conditioner. The calcium carbonate equivalent of the AASP is
approximately 90%.
C. Distribution of AASP
The AASP produced at the McAlpine facility is a safe product for beneficial use.
The PFRP product has a high pH which minimizes the leaching of metals that may
be present in the original sludge. Additionally, nitrogen is not the limiting land
applied constituent, since in the PFRP process excess nitrogen in the form of
ammonia is driven off in the exothermic reaction. The AASP has a calcium
carbonate equivalency of approximately 90% thereby making it an excellent organic
liming agent. AASP loading rates would be limited by its lime content. Labeled
instructions will be attached to all packages of the AASP and distributed .to bulk
13

users along with directions to follow for proper use. Each end -user will be issued an
"End -User Certificate", a copy of which is shown below. This information, which
includes grower's name, field location, soil type and pH, application rate, total tons
sold, and the grower's address and telephone number, will be recorded and kept on
file at all times at the McAlpine Creek WWMF. As with any agricultural product,
the misuse will result in lower yields or the potential for soil contamination.

The AASP produced at the McAlpine facility can be distributed in several
different manners to benefit the agricultural industry. AASP will beneficially enhance
the cultivation of crops in the state of North Carolina. The material offers excellent
liming characteristics along with good soil conditioner qualities. The AASP contains
large amounts of lime at a more economical price than commercial lime products.
Unlike manures and other nutrient enrichers, the AASP contains no seeds, therefore
the germination of weeds is reduced, diminishing the need for herbicides. The
__- product also contains small amounts of nitrogen, phosphorous, and potassium. The
rate limiting constituent will be the neutralizing capability of the AASP on each soil
type.
There will be responsibility to educate each farmer on the proper spreading
techniques if he/she chooses to spread the product on their own. The farmers who
choose to handle the AASP have the equipment and experience to spread their own
manures and fertilizers with meticulous detail and scrupulous care.
D. Product Information
1. AASP Application Rates
Application rates for AASP were determined by the liming potential of the
material, since this is the most limiting component of the product. Nitrogen is not
a consideration in application rates because. the amount of nitrogen applied by AASP
at typical agricultural lime rates is insignificant. Also, the advanced alkaline
stabilization process significantly reduces the nitrogen content of the sludge. This
reduction is due to (1) dilution with alkaline material solids and (2) ammonia
volatilization. Alkaline material, which has no nitrogen value, is added to the sludge
at approximately a 2:1 (dry weight) ratio or less, reducing the nitrogen by one-half.
Nitrogen reduction also results from the volatilization of ammonia which occurs
during the process. Alkaline material addition raises pH which drives off ammonia
gas and also causes chemical mineralization of some of the sludge's organic nitrogen
with resulting additional ammonia formation and volatilization.

gas and also causes chemical mineralization of some of the sludge's organic nitrogen
with resulting additional ammonia formation and volatilization.
As a result of the chemical mineralization, the remaining organic nitrogen is less
readily available and the expected mineralization rate of this remaining nitrogen is
lower than that of the untreated sludge. The AASP material, therefore, exhibits a
mineralization rate of approximately 20 percent.
Application rates for AASP were developed based on the recommendations for total
oxide additions shown in Table 1. A sample of AASP was analyzed for CaCO3
equivalency and was found to be 87.82%. Based on the molecular weights of CaO
and CaCO3, and Cak value of AASP is calculated as follows:
Molecular Weights:
Ca=40,0=16,C=12
CaO = 56
CaCO3 = 100
x = 87
56 100
x = 0.4872 (49% CaO)

The total oxides requirement from the previous table are then divided by the CaO
content of AASP (49%). The resulting number is then divided by 2,000 to convert
to a dry ton per acre rate. This number is then adjusted to reflect a wet ton/acre
rate, using the average percent solids of the material to convert to wet tons/acre. At
an average 60 percent solids of the material, dry tons are converted to wet tons using
a factor of 1.6 (100 divided by 60). The following illustrates the generic formulas for
these calculations and a specific example for CMUD's AASP.
Generic formula:
1. lbs. of oxide required/acre = lbs. AASP required/acre
CaO value of AASP
2. lbs. AASP required/acre = dry tons AASP required/acre
2,000 lbs/dry ton
3. Dry tons AASP required/acre x 100 = wet tons of AASP
% solids AASP required/acre
Example: 1. 1000 lbs. = 2040.8 lbs.
0.49
2. 2040.8 = 1.02 dry tons/acre
2,000
3. 1.02 x 100 = 1.7 wet tons/acre
60
As shown in the example above, a typical application rate will be 1.7 wet tons per
acre. Assuming that 1500 lb. of total oxides were required, the loading rate would
be 2.5 wet tons per acre. Average plant available nitrogen in the AASP is 7.4 lb/dry
ton (3.7 lb/wet ton). At the higher application rate of 2.5 wet tons/acre, only 9.25 lb.
of nitrogen/acre would be applied. This insignificant amount of nitrogen in terms of
I:

crop requirements means that nitrogen will not limit the application rates .for the
AASP.

PRODUCT INFORMATION LABEL
AGRICULTURAL USE
AASP is a mixture of lime products and municipal wastewater biosolids
generated at the Charlotte -Mecklenburg Utility Department's wastewater
treatment plants. Mixing biosolids and lime generates a heat reaction
which pasteurizes the material killing potentially harmful bacteria and
pathogens. AASP meets and exceeds rigid safety standards specified by
EPA.
AASP is. an effective liming agent for agricultural crops and with
reasonable care can greatly enhance the growing conditions of the crops.
It has approximately the same liming potential as agricultural limestone.
In addition, it is an organic material that will help improve soil conditions
and tilth. Application rates are based on the soil pH of the field to be
limed. The attached rate chart should be used when applying AASP.
AASP should only be used when an increase in soil pH is desired.
Like most agricultural products AASP must be handled with care to insure
protection of the environment. Similar to other lime products, this
material can be an eye or skin irritant; avoid prolonged contact with bare
skin. Consideration should be given to store the material in an area that
will not cause excessive runoff or loss of material in heavy rains. When the
material is unloaded, spread or temporarily stored, care should be taken
to maintain appropriate setbacks from dwellings, wells, public roads,
streams and areas with steep slopes that would promote runoff.

AASP is an effective liming agent for agricultural crops and with
reasonable care can greatly enhance the growing conditions of the crops.
With a liming potential similar to agricultural limestone, it can be used to
adjust soil pH. Since it contains some organic material, it can help
improve soil conditions and tilth if worked into the soil. Like other types
of line, this material can be an eye or skin irritant; avoid prolonged
contact with bare skin.
Application rates should be based on the soil pH. AASP should only be
added if the soil pH is below 6.5. Elevated pH can result in nutritional
deficiencies for many plants. Use the chart below to determine the
application rate of AASP. AASP Application Rates (lbs/100 sq.ft.).

NOTE: Since the amount of alkaline material to meet PFRP temperatures
is much higher than that required for pH of 12 for 2 hours, pH monitoring
is not needed as frequently as temperature monitoring. Note that the pH
values presented here are not representative of the sample. pH probe has
been removed.

II rior to application or incorporation. Please attach supporting calculations to substantiate
co liance with 40 CFR Part 257, Appendix II.
IV. MAT9R-IAL TRANSPORT AND APPLICATION
1. For eac source, please attach an explanation of how the residual will be delivered to the
land app ' ation site (in leak proof trucks to a terragator, etc.) and what type of equipment
will be u 'hjed for land application ( terragator, etc.).
2. Please attach allk explanation of how the land application of the residual will be controlled to
insure that there 's proper distribution over the site.
3. Will the operation 'lize a contractor who specializes in Residual Management or will the
permittee manage th rogram? Contractor Petmittee _ If a contractor is utilized,
please provide the na of the firm, a contact, address, and telephone number.
V . SITE EVALUATION AND RECOMMENDED LOADING RATES
1. For each site, please attach a to evaluation of the site/sites by a soils scientist (the
evaluation must be signed by th soil scientist) which addresses soil color, the depth,
thickness and type of restrictive hon\.If
resence or absence of a seasonal high water
table or bedrock within three vertof the deepest point of sludge or residual
application; and cation exchange caphe depth to either groundwater or bedrock is
less than three feet, please also attaonstration, using predictive calculations or
modeling methods acceptable toctor of the Division of Environmental
Management, that the use of thisnot result in contravention of classified
groundwater standards as contaiAC 2L'.0200. In no case shall the
separation .be less than one.foo
2. Please attach a representative soils analysis of each 'te. The soils analysis shall include the
following parameters along with any other significant arameter that has been shown to be

Sodium
Potassium
Nickel
Lead
Cadmium
Zinc
Copper
Magnesium
Calcium

3. In order to determine if the site(s) can be permitted, an evaluation must be m e to establish
whether the residuals are compatible with the soils on each site. For eac site, please
attach a soil scientist recommendations concerning application rates for liq 'ds, solids,
nitrogen, phosphorus, heavy metals, salts and any other significant contaminan know to
be in the sludge or residual.
4. In order to assist DEM in the review of the proposed loadingrates,
