Land Application of Wastewater Residuals
Avery County
Dear Mr. Knight:
In accordance with your application received on May 31, 1994, we are forwarding herewith Permit
No. WQ0002068, dated November 30, 1994, to the Linville Land Harbor Property Owners Association
for the continued operation of a wastewater residuals land application program.
Please be advised of condition VI. 11, which states, "Prior to the next application of the subject
residuals to the land contained herein, the permittee must provide data which verifies that the pathogen
reduction and vector attraction reduction requirements are being met. The data should be submitted to the
Permits & Engineering Unit for review. Upon completion of that review, the permittee will be notified by
letter whether the subject residuals meet the specified requirements. No land application of residuals shall
be allowed under this permit until a letter of permission is received from the Division."

specified therein. Please pay particular attention to the monitoring and reporting requirements contained in
this permit. Failure to establish an adequate system for collecting and maintaining the required operational
information will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of North

continued operation of a wastewater residuals land application program consisting of the application of
approximately 8.50 dry tons per year of residuals from the Linville Land Harbor wastewater treatment
facility to approximately 6.35 acres of land in Avery County (listed in condition VIA) with no discharge of
wastes to the surface waters, pursuant to the application received on May 31, 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.

may be rescinded unless the sites are maintained and operated in a manner which will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.
2. 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.
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 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.

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

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.
