received October 25, 1999, and in conformity with the project plan, specifications, and other supporting data
subsequently filed and approved by the Department of Environment and Natural Resources and considered a part of
this permit
This permit shall be effective from the date of issuance until February 28, 2005, shall void Permit No.
WQ0002838 issued January 8, 1998, and shall be subject to the following specified conditions and limitations:
L PERFORMANCE STANDARDS
1. The spray irrigation facilities shall be effectively maintained and operated at all times so that there is no
discharge to the surface waters, nor any contamination of ground waters which will render them
unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including the
creation of nuisance conditions or failure of the irrigation area to adequately assimilate the wastewater, the
Perry ittee shall take immediate corrective actions including those actions that may be required by the
Division of Water Quality (Division), such as the construction of additional or replacement wastewater
treatment and disposal facilities.
2. 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.
The residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.

The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separa-
ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between wastewater treatment units and wells, and
g) 50 feet between wastewater treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for this waste
treatment and disposal system. These buffers are not intended to prohibit or prevent modifications, which
are required by the Division, to improve performance of the existing treatment facility. These buffers do,
however, apply to modifications of the treatment and disposal facilities which are for the purpose of
increasing the flow that is tributary to the. facility. These buffers do apply to any expansion or
modification of the spray irrigation areas and apply in instances in which the sale of property would cause
any of the buffers now complied with, for the treatment and disposal facilities, to be violated. The
applicant is advised that any modifications to the existing facilities will require a permit modification.
