FALL CREEK <br /> REPORT OF WASTE DISCHARGE �,�� ENGINEERING.INC. <br /> • The average surface loading rates for BOD is within the range found acceptable for <br /> subsurface wetlands designed to treat winery process wastewater. <br /> • The concentration of total nitrogen remaining in the treated effluent and applied to the land <br /> disposal area is projected to be well below the agronomic rate required by the grasses planted <br /> _ in the area. Therefore, the disposal of treated effluent containing nitrogen from the <br /> constructed wetland will not impair groundwater quality underlying the land disposal area. <br /> `• • The total concentration of inorganic dissolved solids (IDS) in the water applied to the land <br /> disposal(with the exception of irrigation water) is relatively low and well below the <br /> agronomic rates for grasses or other more sensitive crops that could be grown in the area. <br /> Further reduction of IDS is expected to occur in the land disposal area soils. <br /> •. • Comparing the total IDS concentration applied to the land disposal area over the year to the <br /> ground water quality objective established for ground water in the San Joaquin Basin set at <br /> 450 mg/L, FCE concludes that the discharge of treated effluent to the land disposal area will <br /> not impair the beneficial use of ground water underlying the land disposal system. <br /> `, • If the IDS loading is determined to be too high for the proposed 0.6 acre land disposal area, <br /> the Winery can apply the water over a larger area. The Winery owns 320 acres of pasture, <br /> vineyards and oak woodlands that could receive the wastewater. <br /> %W <br /> %W <br /> %W <br /> %W <br /> %W <br /> `. <br /> r.. <br /> ,*. <br /> `. <br /> ♦. <br /> JESSIE'S GROVE WINERY 27 FEBRUARY 2004 <br />
