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 Divison of
Water Quality Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535,
2, The Washington 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.
3. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective actions, including those
actions that may be required by this Division, such as the construction of additional or
replacement wastewater treatment or disposal facilities.
4. 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may be rescinded unless the facilities are installed, maintained, and operated in a manner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.
5. 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 North Carolina Division of
Water Quailty.
6. Adequate measures shall be taken to divert stormwater from the high rate infiltration area
and to prevent wastewater runoff.
7. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
8. 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.
9. 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 I or
Class 11 impounded reservoir used as a source of drinking water,
t) 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.
10. 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.
11. The cationic backwash water, anionic backwash water, and supernatant from the iron filter
backwash at the Pine Island water treatment plant will be pumped (Permit No.
WQ0013006) to the high rate infiltration system and shall be combined with wastewater
effluent to a level that will not exceed groundwater standards.
H. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, 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 Certification Commission. The Pere- ttee must also employ a
certified back-up operator of the appropriate type and grade to comply with the conditions
of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A, .0202.
3. The application rates for the high rate infiltration system shall not exceed 7.0 GPDIft2.

IV. GROUNDWATER REQUIREMENTS
The ten (10) monitoring wells (MW-1, MW-2, MW-3, MW-4, MW-5, MW-13, MW-14,
MW-15, MW-16, and MW-17 shall be sampled every March, July, and November, for the
following parameters:
NO3 Total Suspended Solids
Ammonia Nitrogen TOC
COD Chloride
Fecal Colifom- s pH
pH
Volatile Organic Compounds - In November only (by Method 1 or 2 below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods For The
Examination of Water and Wastewater", 17th ed., 1989
Method 2: Method 502.2 "Methods For The Determination Of Organic Compounds
In Drinking Water", U.S. EPA-600/4-88/039
The measurement of water levels must be made prior to sampling for the remaining
parameters. The depth to water in each well shall be measured from the surveyed point on
the top of the casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide the relative elevation of the measuring point for each monitoring well.
If TOC concentrations greater than 10 mg/1 are detected in any downgradient monitoring
well, additional sampling and analysis must be conducted to identify the individual
constituents comprising this TOC concentration. If the TOC concentration as measured in
the background monitor well exceeds 10 mg/l, this concentration will be taken to represent
the naturally occurring TOC concentration. Any exceedances of this naturally occurring
TOC concentration in the downgradient wells shall be subject to the additional sampling
and analysis as described above.
If any volatile organic compounds are detected by Method 6230D, or the equivalent Method
502.2, then the Washington Regional Office Groundwater Supervisor, telephone number
[phone], must be contacted immediately for further instructions regarding any
additional follow-up analyses required. The results of all initial and follow-up analyses
must be submitted simultaneously.
The results of the sampling and analysis shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.O. Box 29578 Raleigh, N.C. 27626-0578 on Form GW-59
[Compliance Monitoring Report Form] every April, August, and December.
