conditions, the Permittee 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 or disposal facilities.
3. 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rescinded unless the facilities are installed, maintained, and operated in a manner which will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.
4. The residuals generated from these treatment facilities mustbe disposed in accordance with
General Statute 143-215.1 and in a manner approved by the Division.
5. Adequate measures shall be taken to divert stormwater from the high rate infiltration area and to
prevent wastewater runoff.
6. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
7. 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.
S. 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,

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.
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
