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.
C. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass directly to receiving waters without treatment of all or any portion of the
influent to such station or facility.
d. Any time that self-monitoring information indicates that the facility is not in
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report 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.
MEKHRIMIL Diem
1. The influent and effluent from the treatment system shall be sampled once every two (2)
weeks for the first three (3) months and monthly thereafter for the parameters specified
below;
pH
BTEX - using EPA method 602
MTBE - using EPA method 602
2. Groundwater monitoring wells MW -1, MW -2, MW -4, and MW -5 shall be sampled every
January and July for the following parameters:
Water levels
BH
TEX - using EPA method 602
MTBE - using EPA method 602
The water level shall be made prior to sampling for the remaining parameters.
3. The two (2) current supply wells on site shall be abandoned according to NCAC15 2C
.0113 and under the supervision of the Washington Regional Office.
4. The results of the sampling and analysis shall be sent to the Groundwater Section on Form

Environmental Management shall be provided
7. The Cgmpliance B n delineated on the attached site map for the disposal system is
specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. 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 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

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.
8. All components of the groundwater recovery, treatment and disposal system shall be
properly weather -proofed to prevent freezing and failure of the system.
9. Two (2) weeks prior to system start-up, the Permittee shall notify the Division of
Environmental Management's Washington Regional Office that operation is about to
commence.
10. The groundwater recovery treatment and disposal system shall be inspected weekly. If it is

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.
