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
Convalescent Center of Sanford
Lee County
FOR THE
continued operation of a 15,720 GPD spray irrigation treatment and disposal facility consisting of a grease trap,
three septic tanks, a 4,560 square foot sand filter, a thirty day storage pond, a chemical feed chlorinator, a 2,000
gallon chlorine contact tank, duplex irrigation pumps with automatic irrigation timer and an eight acre spray
irrigation field with five zones to serve Convalescent Center of Sanford, with no discharge of wastes to the
surface waters, pursuant to the application received May 7, 2002, 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 November 30, 2007, shall void Permit No.
WQ0007026 issued October 3, 1997, and shall be subject to the following specified conditions and limitations-.
I. PERFORMANCE STANDARDS
The spray 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 (Division), such as the construction of additional or
replacement wastewater treatment and 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. 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.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.

The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separate
ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 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.
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 spray irrigation 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.
11. OPERATION AND MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Water Pollution Control System Operators Certification
Comrnission (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 SG .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 trust comply with all other conditions of 15A
NCAC SG .0202.
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.
Adequate measures shall be taken to prevent wastewater runoff from the spray 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 30.16 inches over any twelve (12)
month period at an instantaneous application rate not to exceed 0.25 inches per hour.
S. No type of wastewater other than that from Convalescent Center of Sanford shall be sprayed onto the
irrigation area.
9. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while
normal maintenance is being performed.
10. Public access to the land application sites shall be controlled during active site use. Such controls
may include the posting of signs showing the activities being conducted at each site.

11. Freeboard in the storage pond shall not be less than two feet at any time.
12. A waste -level gauge, to monitor waste levels in the storage pond, shall be installed within 60 days of

Volatile Organic Compounds (VOC) sampled in November

b. For Total Organic Carbon (TOC), if concentrations greater than 10 mg/l are detected in any down -
gradient 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 down -gradient wells shall be subject to the additional sampling and analysis as
described above.
c. For Volatile Organic Compounds (VOCs) sampled in November, use only one of the following
methods:
1) Standard Method 6230D, Practical Quantitation Limit (PQL) at 0.5 ug/L or less

3) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less
4) EPA Method 8260, Low Concentration, PQL at 0.5 ug/L or less
5) Another method with prior approval by the Groundwater Section Chief.
Any of the referenced methods used for VOCs must at a minimum, include all the constituents listed
in Table VIII of Standard Method 6230D. Any method used must provide a PQL of 0.5 ug/L or less,
which must be supported by laboratory proficiency studies as required by the DWQ Laboratory
Certification. Unit. Any constituents detected above the Method Detection Limit (MDL) but below the
PQL of 0.5 ug/L must be qualified (estimated) and reported.
d. Any laboratory selected to analyze parameters must be Division of Water Quality (DWQ) certified
for those parameters required.
If any volatile organic compounds are detected by the methods listed, then the Raleigh 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.
4. The measurement of water levels must be made prior to sampling for the retraining parameters. The
depth to water in each well shall be measured from the surveyed point on the top of the casing.
5. 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.
6. 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.
7. The results of the sampling and analysis must be received on Form GW-59 (Groundwater Quality
Monitoring: Compliance Report Forth) by the Groundwater Section, Permits and Compliance Unit,
