Permeability studies <br />on the study area indicate that the underlying aquifer could completely <br />drain in 10 months if there were no recharge, so impacts from reduced <br />seepage should be measurable during the monitoring period for Stage One. <br /> <br />A vegetation and wildlife monitoring program would be implemented <br />in the Stage One area to determine changes in wildlife habitat and pop- <br />ulations after construction of salinity control measures. Aerial photo- <br />graphs and population sampling programs would provide data to lead to <br />estimates of population densities in various habitat conditions including <br />project developed wildlife habitat. The results of these studies will be <br />used to improve projections for impacts on wildlife from the entire unit <br />and will be used in arriving at further planning decisions for the unit. <br /> <br />Appropriate permits will be obtained from regulatory agencies. Dis- <br />charge (402) permits will be needed for point source discharges such as <br />might occur at concrete operations. <br /> <br />Information gained from Stage One monitoring will clarify the level <br />of effectiveness of the salinity control measures and wildlife develop- <br />ment measures, and this body of data will be used to arrive at future <br />planning decisions for the overall unit. <br /> <br />A_I. <br />
