best management practices indicates minimization of
disturbance to the hydrologic balance.
Surface water— Monitoring data reported for springs and
ponds was consistent with baseline data and the predicted
impacts identified in the PHC section on page 2.05 -115 of C-
1996 -083. Conductivity was above average at the majority
of the sites when compared to baseline data.

been collected from these sites. A determination of
compliance cannot be made due to a failure to collect and
submit the required data.
