Dear Mr. Howe:
On February 14, 1991, the Division of Environmental Management issued Perrot No.
WQ0004059 to Sugarloaf Properties, Incorporated for the continued operation of the subject
wastewater treatment and disposal facilities. On March 20, 1991, the Division received a letter
from you objecting to the numerical parameter concentrations specified in condition IV.3 of the
permit. Upon further review, the Division has determined that the numerical concentrations can be
deleted from the permit, therefore, Permit No. WQ0004059 is being reissued without the numerical
concentrations specified or the paragraph which explains the numbers. All other conditions and
limitations remain the same.
This permit shall be effective from the date of issuance until January 31, 1996, shall void
Permit No. WQ0004059, which was issued on February 14, 1991, and shall be subject to the
conditions and limitations as specified therein. Please pay particular attention to the monitoring
requirements in this permit. Failure to establish an adequate system for collecting and maintaining
the required operational information will result in future compliance problems.
This modified permit shall be final and 'binding. If you require additional information
concerning this matter, please contact Mr. Randy Jones at 919/ 733-5083.
Sinc rely,

IV. GROUNDWATER REQUIREMENTS
Within 90 days of permit issuance, monitoring well No. 2 shall be properly
abandoned in accordance with 15 NCAC 2C .0113.
2. Within 90 days of permit issuance, one (1) downgradient monitoring well shall be
installed to monitor groundwater quality. The well shall be constructed such that the
water level in the well is never above or below the screened (open) portion of the
well at any time during the year. However, the exact location and construction
details for these wells must be approved by the Wilmington Regional Office, from
which a well construction permit must be obtained.
5

3. The new monitoring well along with the two remaining existing monitoring wells
must be sampled every March, July, and November for the following parameters:
TOC
Ammonia Nitrogen
Water Level
Total Phosphorus
`IDS
pH
Chlorides
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 relative to mean sea level (M.S.L.). The depth of the water in each well
shall be measured from the surveyed point on the top of the casing. The water level
elevations shall then be determined relative to (M.S.L.).
If TOC concentrations greater than 10 mg/l 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 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.
4. The ground surface elevations and the measuring points (top of well casing) of all
monitoring wells shall be surveyed relative to mean sea level (M.S.L.). The water
level in each monitoring well shall be measured to the nearest 1/100 ft and the
groundwater flow calculated. The above information shall be submitted to the
Wilmington Regional Office within 120 days of permit issuance.
5. Within 120 days of permit issuance Sugarloaf Properties, Incorporated shall
determine the exact location of all monitoring wells and submit to the Wilmington
Regional Office a survey plat detailing these locations.
21

6. The Compliance Boundary delineated on the attached map 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 143-215.6(1)a. The sale of
property, by the Pemiittee, 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, 1483, the Compliance Boundary is
established at the lesser of 250 feet from the perimeter of waste disposal, 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 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.
7. All monitoring wells shall be equipped with vented caps and locks to prevent
unauthorized access.
S. Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
