FOR THE
continued operation of a 8,640 GPD subsurface wastewater disposal system consisting of three (3) 2,880
GPD capacity septic tanks and drainfield systems, gravity sewers, a grinder pump station with high water
alarm and stand-by generator, and 3 -inch force mains to serve 72 bedrooms in Heronwood Development
with no discharge of wastes to the surface waters, pursuant to the application received April 6, 1992 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.
This permit shall be effective from the date of issuance until June 30, 1997, and shall void Permit
No. 15135 issued September 17, 1987 and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE_ STANDARDS
1. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those
as may be required by this Division, such as construction of additional or replacement
wastewater treatment or disposal facilities.
2. 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.
3. This permit shall become voidable if the soils fail to adequately absorb 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be rescinded unless the facilities are installed, maintained, and operated in a manner which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.
4. Adequate measures shall be taken to divert stormwater from the disposal area and prevent
wastewater runoff from the subsurface disposal field.
5. The sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.

6. A usable reserve area shall be maintained for wastewater disposal. The reserve area shall

MONITORING AND REPORTING REQiiiREMENT
1. Any monitoring deemed necessary by the Division of Environmental Management to insure
surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.
2. The low pressure lines shall be maintained as necessary (including purging of the lines and
pressure testing) in order to ensure that they remain free of obstructing materials and that
the pressure head on the laterals remains within the design specifications. The highest and
lowest laterals on each subfield shall be checked (and adjusted as necessary) annually to
ensure that the pressure heads are within the approved specifications. If adjustments are
necessary to the highest and lowest laterals, the remaining laterals in that subfield shall also
be checked and adjusted to the approved specifications. Adequate records showing all
maintenance shall be maintained by the Permittee. These records should include but are not
limited to the following:
Items Inspection Frequency
a) Individual dosing pump operation Monthly
b) Individual field rotation Monthly
C) High water alarms Monthly
d) Residual pressure on highest and
lowest lateral on each subfield Annually
3. Three copies of all operation and maintenance records (as specified in condition III 2) shall
be submitted on or before January 31 of the following year to the following address:
NC Division of Environmental Management
Water Quality Section
Facility Assessment Unit

Raleigh, NC 27626-0535
4. A record shall be maintained of all residuals removed from this facility. This record shall
include the name of the hauler, permit authorizing the disposal or a letter from a
municipality agreeing to accept the residuals, date the residuals were hauled, and volume of
residuals removed.
5. Noncompliance Notification:
The Permittee shall report by telephone to the Mooresville Regional Office, telephone no.
[phone], as soon as possible, but in no case more than 24 hours or on the next
working day following the occurrence or first knowledge of the occurrence of any of the
following:
a. Any occurrence at the wastewater treatment facility which results in the treatment of
significant amounts of wastes which are abnormal in quantity or characteristic, such
as the dumping of the contents of a basin or tank; the known passage of a slug of
hazardous substance through the facility; or any other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.
3

C. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass of all or any portion of the influent to such station or facility.
d. Any time that self-monitoring information indicates that the facility has gone out of
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written repprt in letter
form within 15 days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.
IV. (tRQUNDWATER EMUIREMENTS
The three (3) existing monitor wells shall continue to be sampled every March, July, and
November for the following parameters:
NO3 TDS
TOC pH
Ammonia Nitrogen Chlorides
Water Level Fecal Coliforms
Total Suspended Solids
Volatile Organic Compounds - In November only (by Method 1 or Method 2
below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods for the
Examination of Water and Wastewater", 17th edition, 1989
Method 2: Method 502.2 " Methods for the Determination of Organic Compounds in
Drinking Water", United States Environmental Protection Agency - 600/4-88/039
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide relative elevations of the measuring point for each of the monitoring wells. The
depth of water in each well shall be measured from the surveyed point on the top of the
casing.
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 backg1ound 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 EPA methods 604 and 611 must also be run to detect other organic compounds
which may be present. The results of all analysis specified in the monitoring requirements,
including 604 and 611 if required, must be submitted simultaneously
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management on Form GW -59 (Compliance Monitoring Report Form) every
April, August, and December.

2. The Compliance Boundary for the disposal system is specified by regulations in 15 NCAC
2L, Classifications and Water Quality Standards applicable to the groundwater of North
Carolina. An exceedance of Groundwater Quality Standards beyond the Compliance
Boundary is subject to penalty provisions applicable under General Statute 143-215.6A.
The sale of property, by the Permittee, which is within or contiguous to the disposal
system site may alter location of the Compliance Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the subsurface disposal areas, or 50 feet within the
property boundary.
If the title to any property which may affect the location of the Compliance Boundary is
changed, the permittee shall notify the Division Director within 14 days. The Director shall
then establish a modified Compliance Boundary which will be done as a modification to the
Permit.
The REVIEW BOUNDARY, delineated on the attached site map for the disposal system is
specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. A
REVIEW BOUNDARY is established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. When the
concentration of any substance equals or exceeds the maximum allowable concentration of
that substance at the REVIEW BOUNDARY, as determined by monitoring, the permittee
shall either (i) demonstrate, through predictive calculations or modeling, that natural site
conditions, facility design and operational controls will prevent a violation of standards at
the Compliance Boundary; or, (ii) submit a plan for the alteration of existing site
conditions, facility design or operational controls that will prevent a violation of standards
at the Compliance Boundary, and implement that plan upon its approval by the Director.
3. Any additional groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
V. INSPECTIONS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal facilities
to prevent malfunctions and deterioration, operator errors and discharges which may cause
or lead to the release of wastes to the environment, a threat to human health, or a nuisance.
The Permittee shall keep an inspection log or summary including at least the date and time
of inspection, observations made, and any maintenance, repairs, or corrective actions
taken by the Permittee. This log of inspections shall be maintained by the Permittee for a
period of three years from the date of the inspection and shall be made available upon
request to the Division of Environmental Management or other permitting authority.
3. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the disposal site and facility at any reasonable time for the
purpose of determining compliance with this permit; may inspect or copy any records that
must be kept under the terms and conditions of this permit; or may obtain samples of
groundwater, surface water, or leachate.
