and subsequent additional information received by the Division, 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, 2008, shall void Permit No.
WQ0002128 issued November 7, 1997, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
In the event that the facilities fail to perform satisfactorily, including the creation of nuisance
conditions, the Permittee shall take in unediate 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 or disposal facilities.
2. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be
rescinded unless the facilities are installed, maintained, and operated in a manner which will protect
the assigned water quality standards of the surface waters and ground waters. The ponding of
wastewater on the surface of the distribution field when the dosing cycle commences shall be
considered as evidence of failure of the soils to adequately assimilate the wastewater. Additionally,
such failure shall be interpreted as a violation of this permit condition.
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. Adequate measures shall be taken to divert stormwater from the high rate infiltration area and to
prevent wastewater runoff. ,
Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
6. 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 following buffers shall be maintained:
a. 400 feet between high rate infiltration unit and any habitable residence or place of public
assembly under separate ownership or which is to be sold,
b. 200 feet between high rate infiltration unit and any private or public water supply source and any
streams classified as WS or B,
c. 200 feet from mean high water between high rate infiltration unit and any "SA" or "SB" classified
surface waters,
d. 200 feet from normal high water between high rate infiltration unit and any other stream, canal,
marsh, or coastal waters,
e. 200 feet -from normal high water between high rate infiltration unit and any Class 1 or Class IT
impounded reservoir used as a source of drinking water,
f. 200 feet between high rate infiltration unit and any other lake or impoundment,
g. 200 feet between high rate infiltration unit and any Drainage systems (ditches, drains, surface
water diversions, etc.) and from any groundwater lowering and surface drainage ditches,
h. 100 feet between high rate infiltration unit and property lines,
i. 50 feet between treatment units and property lines, and
j. 50 feet between high rate infiltration unit and other treatment units and public right of ways.
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 high rate infiltration 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.
8. A usable green area shall be maintained for wastewater disposal. The green area shall have the
capability of accommodating the average daily flow of the facility being served without exceeding
the loading rates of the green area. A "green area", as defined in 15A NCAC 2H .0404 (g)(7), is an
area suitable for waste disposal, either in its natural state or which has been modified by planting a
vegetative cover of grasses or low growing shrubbery.
In accordance with Condition J(1), the Permittee shall have the existing wastewater treatment system
evaluated by a Professional Engineer to determine the adequacy and ability of the system to function
at the permitted flow rate in order to comply with the issued permit. Therefore, a submittal in the
form of a permit modification shall be made specifying the corrective actions needed in order to
comply with permit conditions. All actions to improve operational performance shall be completed
prior to July 1, 2003.
Additionally, within ninety (90) days of permit issuance, a plan of action shall be submitted outlining
the necessary steps to be taken in order to achieve compliance with 2L Groundwater Standards at the
Compliance Boundary.
