Dear Mayor Wayne:
On July 5, 1995 the Division received the Town of Old Fort's application for a Class A residual
handling facility. To insure the Town of Old Fort is complying with 40 CFR 503, along with the issuance
of the Class A distribution Permit No. WQ0011260, we are forwarding herewith modifications to Permit
No. WQ0005282, dated October 9, 1995 to the Town of Old Fort for the operation of a wastewater
residuals land application program. This modification is to include the 40 CFR 503 residual requirements.
No other changes have been made.
This permit shall be effective from the date of issuance until April 30, 1997, shall void Permit No.
WQ0005282, issued May 22, 1992, and shall be subject to the conditions and limitations as specified

In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Town of Old Fort
McDowell County
FOR THE
operation of a wastewater residuals land application program consisting of the application of approximately
55 dry tons per year of residuals from the Town of Old Fort wastewater treatment facility to approximately
140.5 acres of land in McDowell County with no discharge of wastes to the surface waters, 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.

I . The Asheville Regional Office, telephone number 704-251-6208, and the appropriate local
governmental official (county manager/city manager) shall be notified at least twenty-four
(24) hours prior to the initial application of the residuals to a site so that an inspection can
be made of the application sites and application method. 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. In addition, the McDowell County
Manager's office must be notified prior to the initial application so that they will be aware
that the operation has commenced.

may be rescinded unless the sites are maintained and operated in a manner which will
protect the assigned water quality standards of the surface waters and ground waters.
3. The land application program shall be effectively maintained and operated as a non -
discharge system to prevent the 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 program.

5. In the event that the land application program is not operated satisfactorily, including the
creation of nuisance conditions, the Permittee shall cease applying residuals to the sites and
take any immediate corrective actions as may be required by the Division.
6. Some of the buffers specified below may not have been included in previous permits for
this land application operation. However, any sites or fields that are included in this
permit, but were approved with different applicable buffers shall be reflagged to comply
with the below buffers. The following buffer zones shall be maintained:
a) 400 feet from residences or places of public assembly under separate ownership for
surface application method; however, the buffer zone requirement may be reduced to a
minimum of 100 feet upon written consent of the owner and approval from the
appropriate DEM regional office,
b) 200 feet from residences or places of public assembly under separate ownership for
subsurface residual injection method; however, the buffer zone requirement may be
reduced to a minimum of 100 feet upon written consent of the owner and the

coastal waters and any other lake or impoundment for surface application,
e) 50 feet from any streams classified as WS or B, any other stream, canal, marsh or
coastal waters and any other lake or impoundment for subsurface application,
f) 100 feet from property lines for both surface and subsurface application methods;
g) 50 feet from public right of ways for both application methods,
h) 10 feet from upslope interceptor drains and surface water diversions for both
application methods,
i) 25 feet from downslope interceptor drains, surface water diversions, groundwater
drainage systems and surface drainage ditches for both application methods.
7. A copy of this permit shall be maintained at the land application site when residuals are
being applied during the life of this permit. A spill prevention and control pian shall be
maintained in all residuals transport and application vehicles.
8. Specific residual application area boundaries shall be clearly marked on each site prior to
and during application.
9. No residuals at any time shall be stored at any application site, unless approval has been
requested and obtained from the Division of Environmental Management.
