Town of Pilot Mountain
Surry County
FOR THE
continued operation of a wastewater residuals facility for the distribution of Class A residuals consisting of
the distribution of 275 dry tons per year of residuals from the sources listed in Condition II 2, with no
discharge of wastes to the surface waters, pursuant to the application received on March 24, 1997, and in
conformity with the project plan, specifications, and other supporting data subsequently filed and

as a non -discharge system to prevent the discharge of any wastes resulting from the
operation of this program.
2. This permit shall become voidable in the event of failure of the residuals program to
adequately protect the assigned water quality standards of the surface waters and
groundwaters.
3. 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.
4. In the event that the residuals program is not operated satisfactorily, including the creation
of nuisance conditions, the Permittee shall take any immediate corrective actions as may be
required by the Division.

for the disposal system constructed after December 31, 1983 is established at either (1) 250
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

provided.
V . INSPECTIONS
1. The Permittee or his designee shall inspect the residuals storage, transport, and treatment

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
