hazardous substance through the facility; or any other unusual circumstances.
2

AN
b. Any process unit failure, due to known or unknown reasons, that render the facility

1. Groundwater monitoring wells MWA, MW-4, MW-6, MW-7 and supply well WW-2
(located on the R. W. Moore Equipment Company property) shall be sampled immediately
prior to system start-up and thereafter every March, June, September and December for the
following parameters:
Water Levels
pH
NO2
NO3
Volatile Organic Compounds (by Method 1 or Method 2 below)

parameters. The depth of water in each well shall be measured from the surveyed point on
the top of the 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, Post Office Box 29535, Raleigh, N.C. 27626-
0535 on Form GW-59 (Compliance Monitoring Report Form) every April, July, October

boundary, whichever is closet to the waste disposal area. An exceedance of Groundwater
Quality Standards at or beyond the Compliance Boundary is subject to immediate
remediation action on addition to the penalty provisions applicable under General Statute
143-215.6A(a)(1).
Also in accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around
the 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.
6. All components of the groundwater recovery, treatment and disposal system shall be
properly weather -proofed to prevent freezing and failure of the system.
7. The groundwater recovery, treatment and disposal system shall be inspected weekly. If it

e. the relative elevation of the top of the well casing (which shall be known as the
"measuring point"),
f. and the depth of water below the measuring point at the time the measuring point is
established.
10. Upon completion of all well construction activities, a certification must be received from a
professional engineer certifying that the monitoring wells are located and constructed in
accordance with the Well Construction Standards (15A NCAC 2C) and this permit. This
certification should be submitted with copies of the Well Completion Form (GW-1) for
each well. Mail this certification and the associated GW-1 forms to the Permits and
