D. PROGRAM INFORMATION:
1. Materials Handling
The wastewater treatment residuals will be produced and treated on the same site.
The residuals will be pumped from the digesters through a belt filter press and then
conveyed to the alkaline stabilization process equipment. The processed material will
then be placed in a pile for 72 hours for PH and temperature monitoring. Upon
completion of the 72-hour monitoring period, the residuals will be windrowed on a
covered concrete pad for additional drying and conditioning. Leachate from covered
concrete pad will be collected and returned to the wastewater treatment plant. The
dried material will be stockpiled on a portion of the pad until it is disbursed in bulk to
area farmers and landscape professionals. Length of storage will vary depending on
season and demand.
2. Marketability
The finished product will be suited as an agricultural and landscape lime -type product
and mulch additive. The volume of finished product produced at the full 1.0 MGD
design flow is projected to be 793 cubic yards per year (Design Calculations,
Wastewater Treatment Plant Improvements, Town of Maggie Valley; May 1999,
Revised March, 2000). The current 0.3 MGD — 0.4 MGD flow will produce
significantly less finished residual product.
3. Label/Information Sheet
The information sheet that will be provided to the recipients of the residuals is
attached.

Biosolid Product Information Guide
The Maggie Valley Biosolid Product is a combination of highly treated domestic
sewage sludge and either lime kiln dust or cement kiln dust. The high alkalinity
and heat created by the interaction of the lime or cement kiln dust with the
sewage sludge destroys pathogenic organisms and produces a safe agriculturally
beneficial product.
The production of this product is closely regulated by the U S Environmental
Protection Agency and the North Carolina Division of Water Quality. The biosolid
product is carefully prepared and routinely monitored to insure that all product
made available to the public is in compliance with all applicable regulations.
The product is an alkaline material and contains some trace plant nutrients. The
Division of Water Quality has placed the following requirements on the use of this
product to insure that no environmental or health impacts will occur:
The biosolid product shall be used and applied only in a manner consistent with
good agricultural or horticultural practice and the information contained herein.
The product shall not be applied:
• To any site that is flooded, frozen or snow covered;
• Within ten feet of any public or private water supply source (including

H. Residuals Operations and Maintenance Plan
Town of Maggie Valley Wastewater Treatment Plant
Operations and Maintenance Plan
Operational Functions:
During normal operation, mixed liquor from the aeration basins is conveyed by airlifts to the
digester units. In the digesters, the aeration diffusers are periodically turned off to allow the
contents of the basins to settle. Once the sludge is settled and the supernatant has risen to the top
of the basins, additional mixed liquor is conveyed into the basins, thus causing the supernatant to
overflow a weir into the aeration basins. The residuals are then stabilized by digestion,
dewatered by the belt filter press, and then processed through the N-Viro stabilization unit.
The N-Viro unit is designed to achieve Class A pathogen Reduction Requirements by
"Alternative 2: Sewage Sludge Treated in a High pH -High Temperature Process (Alkaline
Treatment [503.32 (a) (4)]." The alkaline admixture raises the pH of the overall mixture to
greater than 12. This pH is maintained for a minimum of 72 hours. The sludge and alkaline
admixture combination is retained in the heat pulse bin to insure compliance with the
requirement to maintain a temperature of 52°C (126°F) at least 12 hours during the period that
the pH is greater then 12. In the heat pulse bin, the sludge is monitored to ensure that the pH and
temperature requirements are meet. Monitoring for fecal coliform and/or salmonellae is also
periodically conducted to ensure pathogen reduction. The processed sludge is then cured and
dried to the required 50 percent solids on a covered concrete pad. The required vector attraction
reduction is achieved by compliance with Option 6 [503.33 (b) (6)], the addition of sufficient
alkali to raise the pH to at least 12 at 25°C (77°F) and maintain a pH greater than or equal to 12
for 2 hours and a pH greater than or equal to 11.5 for 22 more hours. This is achieved during the
pathogen reduction process and the monitoring detailed above is conducted to ensure that the
requirements are met.
According to EPA's criteria in the 40 CFR 503 regulations, sludge may be considered Class A if
both pathogen requirements and vector attraction reduction requirements can be met. The Class
A product can then be made available to agricultural, horticultural, and home users.
Maintenance Schedules:
All equipment utilized in this process is operated and maintained in accordance with the
equipment manufacturer's recommendations. Mechanical equipment is checked for proper
operation prior to each use in accordance with those instruction. All bearings are greased prior
to use on the belt filter press and lime stabilization equipment and all electrical switches are
checked.
Safety Measures:
All equipment is operated in accordance with the safety recommendations contained in their
respective operations and maintenance manuals. The belt filter press is equipped with a safety
Page 1 of 3

rope that surrounds the press which allows the operator to disable the operation of the equipment
by pulling the safety rope.
In addition, all public works staff members are required to attend annual safety training pertinent
to their job responsibilities including, but not limited to blood borne pathogens, fire extinguisher
use, hazard communications, lock out tag out procedures, electrical safety, hearing conservation,
and personal protective equipment.
Spill Response Plan
The primary constituents which comprise the residuals management process include liquid
sludge, liquid polymer and lime kiln dust. Each of these liquid constituents is contained in spill -
containment areas throughout the process. Through these spill -containment areas, any liquid
spill is contained in these areas and is ultimately drained to the head of the wastewater treatment
process. The lime kiln dust is contained in a solo immediately outside the residuals processing
building (under the covered concrete pad). Any spill of this material is easily contained
immediately adjacent to the silo and can be cleaned up promptly. For this reason, no formal spill
response plans is necessary for this process.

Mike Corbin, Backup ORC, Grade 2 WWTP Operator
Seth Boyd, Backup ORC In -Training, Grade 3 WWTP
Frequency and Location of Inspections
Residuals are produced through the use of a batch process. Inspection of the equipment
associated with the process is conducted prior to the start of each batch and throughout the
production run. As described below, sampling and monitoring of this process is conducted on a
quarterly basis with all testing being conducted at an onsite laboratory.

Detailed Description of Monitoring Procedures including Parameters to be Monitored:
As indicated above, residuals are produced utilizing a batch process. Therefore, during testing, a
batch of residuals is monitored for pH and temperature throughout the process.
Page 2 of 3

Sampling Frequency and Procedures to Assure Representative Sampling
To ensure regulatory compliance with the requirements described above, composite samples are
taken from the batch process upon production. These composite samples consist of numerous
smaller samples which are collected from throughout the entire batch to account for any
unforeseen variations in the quality of the batch process. These samples are then combined into
a single sample to be tested. Each sample is then tested daily for conformance with the standards
described above. The results of these daily tests are documented on a worksheet. All equipment
utilized in recording these test results including thermometers and pH meters is regularly
calibrated and certified by an independent testing service. Sampling is conducted on a quarterly
basis including those times that may produce the most limiting pathogen and vector attraction
compliance. Typically, this testing is conducted during January, April, July and October of each
year.
