amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
CITY OF WILMINGTON
NEW HANOVER COUNTY
FOR THE
operation of a residual solids stabilization pilot testing facility consisting of the stabilization of residual
solids by processes as defined by the United States Environmental Protection Agency as being or
equivalent to the Processes to Further Reduce Pathogens for City of Wilmington's Northside wastewater
treatment facility, the Southside wastewater treatment facility, and the Sweeney water treatment facility
with the pilot testing facility to be located at the City of Wilmington's Southside wastewater treatment
facility with no discharge of wastes to the surface waters, pursuant to the application received November
18, 1991 and in conformity with the project plan, specifications, and other supporting data subsequently
filed and approved by the Department of Environment, Health and Natural Resources and considered a
part of this permit.
This permit shall be effective from the date of issuance until February 28, 1993 and shall be subject
to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. The Wilmington Regional Office, phone no. [phone], shall be notified at least
forty-eight (48) hours prior to the initiation of the pilot testing program so that an in-place
inspection can be made. Such notification to the regional supervisor shall be made during
the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
2'. -This permit shall become voidable in the event of failure of the residual solids stabilization
facility to adequately protect the assigned water quality standards of the surface waters and
groundwaters.

II.
3. The residual solids stabilization pilot testing program shall be effectively maintained and
operated as a non -discharge system to prevent discharge of any wastes resulting from the
operation of this program.
4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
5. In the event that the residual solids stabilization pilot testing program is not operated
satisfactorily, including the creation of nuisance conditions, the Permittee shall take such
immediate corrective action as may be required by this Department, including the
construction of additional or replacement wastewater treatment or disposal facilities.
6. Diversion or bypassing of the untreated residual solids or residual solids drainage
wastewater from the residual solids stabilization pilot testing facility is prohibited.
7. Stabilized residual solids should not be used in areas of intense public use (schools,
playgrounds, etc.).
OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities and disposal sites shall be properly maintained and operated at all times.
2. The residual solids stabilization pilot test operation must be conducted under the
supervision of the certified wastewater treatment plant operator required by the Certification
Commission for operation of the Southside Wastewater Treatment Plant, NPDES Permit
No. NC0023973.
3. No residual solids other than the following are hereby approved for use in the residual
solids stabilization pilot testing program in accordance with this permit:
Source CountyPermit Number
Northside WWTP New Hanover NCO023965
Southside WWTP New Hanover NCO023973
Sweeney WTP New Hanover NCO002479
4. All stabilized residual solids shall be stored on the concrete pad during stabilization and
until such time as the product is distributed to the buyer. If an alternate storage site is to be
used, approval must be obtained from the Division of Environmental Management's
Wilmington Regional Supervisor.
2

5. The City of Wilmington's residual solids pilot testing program shall consist of testing the
following stabilization methodsl:
1) METHOD #J: The N-Viro process which involves alkaline stabilization of the
product and then windrowing the product for a period of at least three days with
turning of the product. The product must be raised to a pH >_ 12 and a temperature
of at least 520C for at least 12 hours. After which the sludge mixture must maintain
a pH >_ 12 for at least three days.
2) METHOD ##2: The Willowtech Pasteurization Process which involves mixing the
sludge with an alkaline material which raises the pH _> 12 and temperature of 700C
for at least 30 minutes.
3) The En -Vessel Pasteurization Process which involves mixing the
dewatered sludge with quick lime to produce a product which has a pH ? 12. After
which the product is fed into an En -Vessel Pasteurization Reactor where the
temperature is allowed to raise above 700C for at least thirty minutes.
4) METHOD #4: This process is similar to the Willowtech Pasteurization Process. It
consists of mixing the dewatered sludge with an alkaline material to raise the pH >_
12 for at least 2 hours while maintaining a temperature of at least 700C for at least
30 minutes. This process combines lime stabilization (PSRP) with pasteurization
(PFRP) to produce a PFRP product as stipulated by the EPA.
This permit must be modified should the City of Wilmington desire to test
other stabilization methods as approved by the United States Environmental
Protection Agency.
6. Stabilized residual solids shall not be marketed when the criteria for the processes as stated
in condition I1-5 are not meet. Stabilized residual solids which do not meet the Processes
to Further Reduce Pathogens shall be land applied on those lands permitted on the City of
Wilmington's land application of residual solids permit, Permit No. WQ0001271, or
