The Groundwater Section has reviewed the subject permit
application and recommends issuance of the permit with the
following conditions:
(1) Prior to beginning waste disposal operations, four
(4) monitor wells, one (1) upgradient and three
(3) downgradient, must be installed to monitor
groundwater quality. The location and construction
details for these wells must be by approval of the
Washington Regional Office, from which a well
construction permit must be obtained.
(2) The monitor wells must be sampled initially after
construction (and prior to waste disposal operations)
and thereafter every March, July, and November for
the following parameters:
NO pH
Total Ammonia TOC
TDS Chloride
Water Levels Total Coliforms
TOX(In November only)
Orthophosphate
Total Suspended Solids(Initial Sampling
only)
The measurement of water level must be made prior to
sampling for the remaining parameters.
The analytical methods used for TOX must be
capable of detecting the total of all halogenated
organic compounds present at a concentration of
5.0 parts per billion (ppb) or greater. In the
event that a TO concentration of 5.0 ppb or
greater is detected, any individual halogenated
organic compounds present at a concentration at or
above their method detection limit (MDL) must be
identified, quantified and reported with the
sampling results.
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].
(3) Any additional groundwater quality monitoring, as
deemed necessary by the Department, shall be
provided.
