Dear Mr. Kotis:
Subject: Permit No. WQ0013808
Kotis Properties, Inc.
Summerfield Constructed Wetland
Wastewater Drip Irrigation
Guilford County
In accordance with your application received April 29, 1997, we are forwarding herewith Permit
No. WQ0013808, dated February 25, 1998, to Kotis Properties, Inc. for the construction and operation
of the subject wastewater treatment and drip irrigation facilities.
Please note Condition VII.5 which requires all necessary approvals be received for this permit to
be considered valid. If the appropriate approvals are not received, this permit will be considered null
and void.
In addition, please note Condition II.2 which states that should the system not operate
satisfactorily or protect water quality, any and all steps will be taken to protect water quality including
the possibility of closure of the wastewater source until the system has returned to proper operation. The
Division will not issue a discharge permit should this system fail to perform satisfactorily and Kotis
Properties will be responsible for resolving any future failures should they occur.
This permit shall be effective from the date of issuance until January 31, 2003 and shall be
subject to the conditions and limitations as specified therein. This facility is located in the City of
Greensboro's WS-III critical area watershed so several conditions have been included to ensure proper
operation without adversely impacting the water quality of the watershed. Please pay particular
attention to all of the requirements in this permit regarding construction, operation, maintenance,
monitoring and emergency management. Failure to establish an adequate system for operation and
maintenance on the system and failure to provide required 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 the

application received April 29, 1997, 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 January 31, 2003 and shall be
subject to the following specified conditions and limitations:
I. CONSTRUCTION STANDARDS
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. Mail the Certification to the Non-
Discharge Permitting Unit, P.O. Box 29535, Raleigh, NC 27626-0535.

2. The Winston-Salem Regional Office, telephone number 910-771-4600, 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.
3. Location of the permanent wet detention pond shall be located such that all buffers are
being met to the Field A drip irrigation field. Failure to properly locate this pond will be
considered a violation of this permit.
4. At no time shall heavy equipment be allowed on the drip irrigation fields during
construction of the drip irrigation system. The drip irrigation fields shall remain -as a
natural woodlands. All underbrush and small trees which need to be removed shall be cut
and removed by hand prior to operation of the system.
5. Both drip irrigation fields (field A and B) shall be constructed with all the necessary
equipment including the installation of the drip irrigation lines for proper operation prior
to any wastewater being introduced to the system. The flows from this system during the
wetter months of the year will require the application of effluent on Field B.
6. The drip irrigation fields shall also be marked with some farm of permanent markers and
signs showing the location of drip irrigation areas and the need to keep equipment off the
sites. These markers shall be installed prior to construction of any. of the other
wastewater transport or treatment systems and shall remain for the life of the permit.
11. PERFORMANCE STANDARDS
Flow shall be limited to 1,700 GPD (flow is from a 24 hour Food Lion grocery store, a
drugstore and a video rental store). No other flow shall be added to the system without
prior approval from the Division of Water Quality. A three year evaluation period
without additional flow will be required before a flow increase request can be submitted
to the Division of Water Quality (Division). After three year's worth of flow data and
monitoring data has been collected and no signs of problems have surfaced, a permit
modification may be requested for an increase in flow with the three year's worth of data
submitted to support the request. Division review will include determination of system
adequacy to handle the additional flow.
2. The drip 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, such as
the construction of additional or replacement wastewater treatment and disposal facilities
or closure of the wastewater source until the problems are corrected.
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 facility.
4. 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.
5. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.

6. 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 wastewater treatment units and wells, and
g) 50 feet between wastewater treatment units and property lines.
7. A leakage test shall be performed on the septic tank and 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.
8. The subject wastewater treatment and disposal facilities shall be connected to an
operational publicly owned wastewater collection system within 180 days of its
availability to the subject facilities, if the subject wastewater treatment or disposal
facilities are in noncompliance with the terms and conditions of this non -discharge permit
or the governing statutes or regulations. Prior to the initiation of these connection
activities, appropriate approval must be received from this Division.
III. OPERATION AND MAINTENANCE REQUIREMENTS

2. Upon classification of the facility by the Water Pollution Control System Operators
Certification Commission (WPCSOCC), the Permittee shall employ a certified
wastewater treatment plant operator to be in responsible charge (ORC) of the wastewater
treatment facilities. The operator must hold a certificate of the type and grade at least
equivalent to or greater than the classification assigned to the wastewater treatment
facilities by the WPCSOCC. The Permittee must also employ a certified back-up
operator of the appropriate type and grade to comply with the conditions of 15A NCAC
