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 December 31, 2009, and shall be
subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. The Permittee leases the project site property from Glenmorangie Limited Partnership, and has a lease
agreement in effect until October 31, 2012. Termination or extension of the lease agreement, as well
as change of ownership, shall require the Permittee to submit for modification of the permit.
2. The Permittee shall have onsite at least one (1) back-up pump for each pump in use (i.e., back-up for
the two Envirofilter pumps, the one 30 gallon basin pump and the storage/pump tank pump).
3. Upon completion of construction and prior to operation of this permitted facility, a certification must
be received from a professional engineer certifying that the permitted facility has been installed in
accordance with this permit, the approved plans and specifications, and other supporting materials. If
this project is to be completed in phases and partially certified, you shall retain the responsibility to
track further construction approved under the same permit, and shall provide a final certificate of
completion once the entire project has been completed. Mail the Certification to the Land
Application Unit, Division of Water Quality, 1636 Mail Service Center, Raleigh, NC 27699-1636.

4. The Wilmington Regional Office, telephone number [phone], shall be notified at least forty-
eight (48) hours in advance of operation of the installed facilities so that an in -place inspection can be
made. Such notification to the regional supervisor shall be made during the normal office hours from
8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays.
5. The surface 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 Permittee shall take immediate corrective actions including those actions that may be
required by the Division of Water Quality, such as the construction of additional or replacement
wastewater treatment and disposal facilities.
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.
7. 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.
8. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
9. The following buffers shall be maintained:
a) 100 feet between wetted area and any residence or places of public assembly under separate
ownership,
b) 50 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 50 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 treatment/storage units and any wells, and
g) 50 feet between treatment units and property lines.
10. A leakage test shall be performed on the septic tanks, Evirofilter and storage/dosing tank to insure
that any exfiltration occurs at a rate, which does not exceed twenty (20) gallons per twenty-four (24)
hours per 1,000 gallons of tank capacity. The engineer's certification will serve as proof of
compliance with this condition.
11. The sand media of the high rate sand filter must comply with the Division's sand specifications. The
Engineer's Certification will serve as evidence that these specifications have been met.
12. If excavation into bedrock is required for the installation of any tankage, the pit shall be lined with a
10 mil synthetic liner.
13. A sanitary tee and filter shall be installed on the effluent pipe of the septic tank. The Engineer's
Certification will serve as evidence that these specifications have been met.
14. The disposal system shall be connected to a rain or moisture sensor that shall indicate when
wastewater application is not appropriate in accordance with Condition H(4) of this permit.
15. 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.

II. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the wastewater treatment and irrigation facilities by the Water Pollution

employ a certified operator to be in responsible charge (ORC) and one or more certified operator(s) to
be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G .0201. The ORC shall visit
the facilities in accordance with 15A NCAC 8G .0204 or as specified in this permit and shall comply
with all other conditions specified in these rules.
3. A suitable year round vegetative cover shall be maintained.
4. Irrigation shall not be performed during inclement weather or when the ground is in a condition that
will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the irrigation field.
6. The facilities shall be effectively maintained and operated as a non -discharge system to prevent the
discharge of any wastewater resulting from the operation of this facility.
7. The application rate shall not exceed a cumulative loading of 13 inches over any twelve (12) month
period at an instantaneous application rate not to exceed 0.2 inches per hour.
8. No type of wastewater other than that from Cincinnati Thermal Spray facility shall be irrigated onto
the irrigation area.
