PERMISSION IS HEREBY GRANTED TO
Town of Stoneville
Rockingham County
FOR THE
continued operation of a wastewater residuals land application program consisting of the application of
approximately 85 dry tons per year of residuals from the Town of Stoneville wastewater treatment facility
to approximately 86.2 acres of land in Rockingham County with no discharge of wastes to the surface
waters, pursuant to the application received on June 22, 1994 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 void Permit No. WQ0002617 issued March 29, 1993 and shall be effective from
the date of issuance until November 30, 1999, and shall be subject to the following specified conditions
and limitations:
I. PERFORMANCE STANDARDS
I. The Winston-Salem Regional Office, telephone number [phone], 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 Rockingham County Manager's office must be notified prior to the initial
application so that they will be aware that the operation has commenced.
2. This permit shall become voidable if the soils fail to adequately assimilate the wastes and
may be rescinded unless the sites are maintained and operated in a manner which will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
appropriate DEM regional office,
c) 100 feet from any public or private water supply source, waters classified as SA or SB,
and any Class I or Class II impounded reservoir used as a source of drinking water for
both methods,
d) 100 feet from any streams classified as WS or B, any other stream, canal, marsh or
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 plan 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 stared at any application site, unless approval has been
requested and obtained from the Division of Environmental Management.
10. Maximum slope for residual application shall be 10% for surface application and 18% for
subsurface applications.
11. When wastewater residuals are applied, the Class A pathogen requirements and site
restrictions in 40 CFR Part 503.32(a) or the Class B pathogen requirements and site
restrictions in 40 CFR Part 503.32(b), and one of vector attraction reduction requirements
in 40 CFR Part 503.33 must be met. Additionally, an evaluation must be performed which
demonstrates the residuals ability to comply with this requirement. Upon request, a copy
of this evaluation must be submitted including all test results and calculations.

feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. An exceedance of Groundwater Quality Standards at or
beyond the Compliance Boundary is subject to immediate remediation action in addition to
the penalty provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the

facilities to prevent malfunctions and deterioration, operator errors and discharges which
may cause or lead to the release of wastes to the environment, a threat to human health, or a
nuisance. The Permittee shall maintain an inspection log or summary including at least the
date and time of inspection, observations made, and any maintenance, repairs, or corrective
actions taken by the Permittee. This log of inspections shall be maintained by the Permittee
for a period of five years from the date of the inspection and shall be made available to the
Division of Environmental Management or other permitting authority, upon request.
2. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the application site or facility at any reasonable time for
the purpose of determining compliance with this permit; may inspect or copy any records
that must be kept under the terms and conditions of this permit; and may obtain samples of
groundwater, surface water, or leachate.
