SUBSURFACE DISPOSAL SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North
Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Brunswick Community College
Brunswick County
FOR THE

and high water alarms, approximately 300 feet of 6 inch force main, 12,750 square feet of low
pressure disposal field using 2,500 linear feet of pressure distribution lines, and associated
piping, valves, and appurtenances to serve the Odell Williamson Auditorium with no discharge of
wastes to the surface waters, pursuant to the application received April 29, 1991 and in
conformity with the project plan, specifications, and other supporting data subsequently filed and

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.
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.

4. 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.
5. 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and may be rescinded unless the facilities are installed, maintained, and operated in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.
6. Adequate measures shall be taken to divert stormwater from the disposal area and
prevent wastewater runoff from the subsurface disposal field.
7. 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,
8. A usable reserve area shall be maintained for wastewater disposal. The reserve area
shall have the capability of accommodating the average daily flow of the facility
being served without exceeding the loading rates of the reserve area while meeting
all required buffer requirements.
9. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
10. The following buffers shall be maintained:
a) 100 feet between disposal area and any public or private water supply including
wells
b) 100 feet between disposal area and "SA and SB" classified surface waters
c) 50 feet between disposal area and any stream, lake, river or natural drainageway
d) 50 feet between disposal area and property lines
e) 10 feet between disposal area and surface water interceptor drains or diversions
(upslope)
f) 25 feet between disposal area and surface water interceptor drains or diversions
(downslope) and groundwater drainage systems.
11. 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) hour per 1,000 gallons of tank capacity. The engineer's
certification will serve as proof of compliance with this condition.
IL 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 waster treatment plant operator to be in responsible charge
of the wastewater treatment facilities. The operator must hold a certificate of the
type and grade at least equivalent to the classification assigned to the wastewater
treatment facilities by the Certification Commission. Once the facility is classified,
the Permittee must submit a letter to the Certification Comnussion which designates
the operator in responsible charge within thirty days after the wastewater treatment
facilities are 50% complete.
3. The application rates to the disposal field shall not exceed 0.6 gallons/ square foot/
day.
2

4. 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.
5. No traffic or equipment shall be allowed on the disposal area except while
installation occurs or while normal maintenance is being performed.
6. A suitable cover shall be maintained on the LPP field(s) and the field(s) shall be
routinely mowed. The clippings shall be periodically removed to prevent the
build-up of thatch.
MONITORING AND REPORTING REQUIREMENTS
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:
Ite-ma Inspection Frequency
a) Individual dosing pump operation Monthly
b) Individual field rotation Monthly
c) High water alarms Monthly
