DATES OF DISPOSAL The Tracy plant usually starts processing raw product about July 1 and finishes about September 25. But,the season can begin as early as June 25 and end as late as October 15. Spreading of liquid waste on the proposed site would occur only when the raw product is being processed. AMOUNT OF MATERIAL Historically(three years data), the number of gallons of liquid waste hauled and spread from the Tracy plant varies from a low of zero to a high of 50,000 gallons per day. The wash water component of the waste remains fairly constant through the season because the number of loads is virtually the same every day. The peak generation of serum comes when the weather is hot and when the fiuit is mature and soft and thus easily broken. The maximum number of gallons is usually late July through mid August. EVAPOTRANSPIRATION Evapotranspiration(ET)is the evaporation(E)from soil and plant surfaces. Transpiration (T)is the evaporation that takes place within plant leaves and the vapor that diffuses into the air through stomata on the leaf surface. The following are ET values for Tracy( CMS weather stations- California Department of Water Resources) ET(inches of water evaporated per day) July August September 0.25 0.22 0.17 IMPACT OF MATERIAL ON SITE Even the maximum gallonage would have little effect on the proposed site. Acre Inches An acre foot of water is the amount of water required to cover an acre to one foot in depth. One acre foot is 325, 850 gallons(43,560 cubic feet). The maximum daily output of 50,000 gallons amounts to 0.153445 acre feet per day(50,000/325,850). This is 1.84 acre inches per day (12 inches x 0.153445). Impact If 1.84 acre inches would be spread on 10 acres, all of the moisture evaporates in less than 24 hours(1.84/10 acres= 0.18 with ET = 0.17-0.25 Even if we spread over 20 acres,the moisture would evaporate in less than 12 hours(1.84/20 acres= 0.09).
