This memo is to clarify the "Enforcement" page of the inspection
report dated February 4, 1994 for the Twin Pines mine site and NOV
C-93-104 termination.
Observation and Facts:
Upon inspection, all grading of the bench and drainage structures
on the refuse pile reclamation was found to be complete. The
remaining step in the final reclamation of the refuse pile included
the placing of the geotextile fabric on the upper bench and a
portion of the ditches. Due to the need to use the bench by the
AML Program for access to the old utility road for purposes of
reclamation, the final placement of this fabric will be delayed
till spring 1994. Laying of the geotextile fabric does not
constitute an abatement step as defined in the original NOV, rather
it is an additional insurance against erosion in the final
reclamation plan for the pile as outlined in the Technical Revision
submitted as abatement for the NOV.
Termination•
Therefore, the NOV was terminated since the operator had
accomplished all that was at this time, possible to address the
concern outlined in the NOV, mainly surface water drainage off the
pile. The abatement steps for the NOV have been accomplished -
submit a Technical Revision addressing the drainage off the pile
and implement the revision.
In addition to submitting the TR, the operator had previously
constructed a dirt berm at the toe of the refuse pile, thus
allowing the surface flow to exit to the drainage ditch and into
the upper bench sediment pond. This interim abatement step was
made on July 16, 1993 and remained in effect until actual
reclamation of the refuse pile began in mid-January 1994.
