RE: New Elk Mine; Permit C-81-012
NOV C-94-19
Dear Mr. Long:
During the complete inspection of the New Elk Mine held during
August 10 through 12, NOV C-94-019 was issued. This NOV was
written for failure to maintain ditches and culverts. Basin
Resources is requesting vacation of this NOV. The following ie a
summary of the events that took place which we feel warrant
vacation.
Events Surrounding the Problems Cited in the NOV
The New Elk Mine permit require the structures identified in
the NOV to be designed to handle a 10 year/24 hour precipitation
event. For this mine, such a storm corresponds to 2.9" of
precipitation for the entire 24-hour period.
However, the storm of August 3 exceeded the 10 year/24 hour
precipitation event standard, and for that reason alone caused the
conditions identified in the NOV. A total of 2.99" of rain fell
during this event, of which 2.65" fell during an intense 4 hour
period. It was this intense cloudburst that caused the problems
which were seen during the inspection.
Immediately following the August 3 storm, Basin began
remedying the problems caused by the storm. Hasin committed
substantial resources to this cleanup: it devoted approximately
500 man-hours and $20,000 to cleanup activities from the time of
the storm until the inspection tour ended. Hasin personnel and
outside contractors worked steadily to remedy the problems, except
where a
labor dispute and wet conditions interrupted the remedial work.
