The Division is concerned that the relocation of monitoring sites may <br />result in a lack of continuity in the monitoring program.

In the second full paragraph on page 8 of Section 2.05.6(3), it is stated that calculations were <br />made that determined that there would not be significant impact to receiving stream water <br />quality and water rights due to mine discharges. Please provide the calculations or reference <br />on page 8 where in the permit application these calculations can be found. <br />4. In the second full paragraph on page 8 of Section 2.05.6(3),. it is stated that present or <br />potential uses of the water were not considered in the determination of no significant injury <br />to receiving stream water quality and water rights due to mine discharges.

On page 6 of Section 2.05.6(3), Protection of the Hydrologic Balance, it is stated that <br />excessive leakage from the sediment ponds will be avoided by compaction of the pond <br />bottoms and sides. Please explain what "excessive" is and why the ponds should not be <br />lined. <br />8. In the second paragraph on page 9 of Section 2.05.6(3), it is stated that water augmentation <br />during the irrigation off season will not be required. However, it is stated elsewhere in the <br />permit text that off season water is diverted into the irrigation system to fill cisterns etc. <br />Please explain why water augmentation would not be needed during the irrigation off <br />season. <br />All remaining sections of the Rules will also be incorporated into Part 2 of the Division's PAR. <br />
