The twenty one pages of Tables in Appendix 9 that precede these AccuLabs data contain ICP
data which aze those data characteristically generated for McClelland Laboratories as part of
the humidity cell data. As is evident from the tabulations, the ICP scan provides data for
many more parameters than are necessary to evaluate water quality and some reporting limits
are higher than the ICP and AA analyses conducted to generate the AccuLabs data.
However, these additional ICP data have been generated for consistency with prior reports.
CC&V plans to soon discontinue the ICP analyses based on the adequacy of the current data
if the OMLR agrees, but we have not discontinued any analyses, regardless of justifications,
in order to avoid criticism from the OMLR. We presume Dr. Posey focused on these ICP
data rather than the AccuIabs data when he developed his comments.
Again, in summary, the vast majority of the reporting limits used for CC&V's routine
analytical work are below the water-quality that might be used to judge acceptability for
Cripple Creek and for Fourmile Creek, the o~ two stream reaches that aze classified in the
area. Mercury is the single exception -and ambient mercury values reported throughout the
submission are at the detection limit of 0.0001 mg/1.
