the actions taken or proposed to be taken to ensure that the problem does not recur.
20. Within 90 days of permit issuance, three (3) monitor wells, downgradient from the
lagoons, shall be installed to monitor groundwater quality. The wells shall be constructed

TDS
Sulfate
pH
Water Level
Chloride
Fluoride
Chromium
Manganese
Iron
Lithium

parameters. The depth of water in each well shall be measured from the surveyed point on
the top of casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide relative elevations of the measuring point for each monitoring well.
The results of the sampling and analysis shall be sent to the Groundwater Section, N. C.
Division of Environmental Management, P. O. Box 29535, Raleigh, N. C. 27626-0535 on

Following installation and inspection of the lagoon liner, and prior to waste
disposal operations, verification o the liner's compliance with hydraulic
conductivity and thickness specifications must be provided to the Division of
Environmental Management, Groundwater Section, by the project engineer.
For the synthetic liner, it shall be at least 30-mil thick and reinforced. It shall be

operations, certification of the liner's compliance with approved construction
specifications and the liner's integrity must be provided to the Division of
Environmental Management, Groundwater Section, by the project engineer.

a. the location and identity of each monitoring well,
b . the location of the waste disposal system,
C. the location of all property boundaries,
d. the latitude and longitude of each monitoring well,
e. the relative elevation of the top of the well casing (which shall be
known as the "measuring point"),
f . the depth of water below the measuring point at the time the measuring
point is established.
The maps shall be sent to the Groundwater Section, N. C. Division of Environmental
Management, P. 0. Box 29535, Raleigh, N. C. 27626-0535.
21. Upon completion of all well construction activities, a certification must be received from a

Boundary is established at either (1) 250 feet from the waste disposal area, or (2) 50 feet
within the property boundary. An exceedance of Groundwater Quality Standards beyond
the Compliance Boundary is subject to the penalty provisions applicable under General
Statute 143-215.6(1)a.
Also in accordance with 15 A NCAC 2L, a REVIEW BOUNDARY (See Attachment A) is
established around disposal systems midway between the Compliance Boundary and the
perimeter of the waste disposal area. Any exceedance of standards at the Review Boundary
shall require remediation action on the part of the Permittee.
30. Upon classification of the facility by the Certification Commission, 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
