RE: NOV C-94-029, Detail of missing spoil spring data, Mine 1,
Mine 2, Eckman Park, {C-81-071
As discussed at the assessment conference on January 6, 1995 for
the above cited NOV, I am providing the following information
pertaining to the missed spoil spring sampling data.
Springs flowing at greater than 35 gpm springs discovered in May of
1992 would be reported in the 1993 Annual Hydrology Report for the
period October 1992 to April 1993. From the May 1992 spring and
seep survey the following springs were determined to be flowing at
greater than 35 gallons per minute (gpm) and therefore should be
visited quarterly for flow and field parameters and semi-annually
for a full suite quality sample.
A-2, C-1, C-2, D comp.
For these springs, the operator contends that D comp. is the full
suite quality site that characterizes all springs in the A-D group.
If that is the case, the flow of the A-C springs should approximate
the flow for D comp., since D comp. is directly below the A-C
series.
Flow of A-C series = 1.862 cfs
Flow of D Comp. = 1.1 cfs
69$ difference in flow.
Regardless of the above relationship, if the Division were to
concede the full-suite quality sample for D comp as meeting the
requirements for A-C full suite sampling, based on flow there would
still be a quarterly requirement for flow and field parameters at
A-C series springs. The following lists the required visits for
the A-C series springs which meet these requirements and also if
and when data was received for each.
