a contour map of the groundwater levels. These maps should be developed using the data
collected in May and November and submitted along with the other monitoring data
collected in those months.
4. 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

standards at the Review Boundary shall require remediation action on the part of the
permittee.
7. All components of the groundwater recovery, treatment and disposal system shall be
properly weather -proofed to prevent freezing and failure of the system.
8. The groundwater recovery treatment and disposal system shall be inspected weekly. If it is

in accordance with 15A NCAC 2C .0108 (Standards of Construction for Wells Other than
Water Supply) and any other State and local laws and regulations pertaining to well
construction.
12. 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
