The FTSF cover will have the storage capacity to hold and transmit infiltration water without <br /> contacting the tailings. During average rainfall events,the soil layer of the cover has the field <br /> capacity to absorb the precipitation until it is evaporated. During storm events when the field <br /> capacity of the soil layer is exceeded, precipitation will flow into the underlying sand and gravel <br /> layer where it will flow laterally to the contact pond. The water quality is expected to reflect <br /> rainwater that has percolated through soil. The cover is expected to accommodate the <br /> precipitation from a 1 in 1,000 year 24-hour storm event. No seepage from the bottom of the <br /> FTSF is expected;therefore, seepage treatment is not expected. Further discussion of the FTSF <br /> cover is provided in the report"Tailings Geochemistry Characterization & Seepage Quality <br /> Estimate— Final Report". <br /> 3. Application Section 2.7.6 has been revised to reflect the following: Water will be supplied from <br /> mine dewatering,the mill water recycling system and a groundwater well. It is anticipated that <br /> mine dewatering and the recycling system will supply a sufficient quantity to operate the mill <br /> since the recycling system is designed to recycle approximately 90%of the mill water or 180 <br /> acre-feet per year. Water may be needed from the groundwater well to initiate the mill <br /> process. After the mill's water recycling system is operating, very little water will be needed <br /> from the groundwater well, if any since dewatering will be an ongoing process. <br /> 3.1.9 Top soiling <br /> 5. Application Section 2.5.2 "Beneficial Use of Removed Trees" has been added to address the <br /> beneficial use of trees removed from the mill site. <br />
