Response to EPA Comments
We submit herein our response to the comments in the US EPA, Region IV,
letter dated November 10, 1981. The responses are numbered/identified
the same as in the referenced letter,
(a) through (c) No response required
(d) Post closure surveilance will be handled by the State through one
of the State Agencies, Police, DOT, etc.
(e) Sediments and the liner from the silt pond are to be removed and
enclosed within the landfill prior to final closure. This is
specified in the specifications, page lSA-4, paragraph 5.6.
(f) We, the consultant, can assure this only if our contract with the
State is extended to cover full-time inspection.
(g) Specification page 2D-l, paragraph 2.2, specifies that final
locations and depths of groundwater monitoring wells shall be
determined in the field. Field conditions may show that a cluster
of wells will be needed to adequately monitor the groundwater.
(h) The area in question is on a hill and as best as can be determined
from the data available at this point in time, there is not a major
fluctuation in groundwater. However, observations made during
construction should provide data for a more positive comment.
