WASTE DISCHARGE REQUIREMENTS ORDER R5-2013-0028 -34- <br /> DELICATO VINEYARDS, INC. <br /> DELICATO FAMILY VINEYARDS <br /> SAN JOAQUIN COUNTY <br /> 2 Based on total flow and concentration for each source of water discharged. <br /> 3. Compliance with the above requirements shall be determined as specified below: <br /> a. The mass of BOD applied to each LAA on a daily basis shall be calculated <br /> using the following formula: <br /> M _ 8.345(CV) <br /> A <br /> Where: M = mass of BOD applied to an LAA in lbs/ac/day <br /> C = concentration of BOD in mg/L based on most recent <br /> monitoring result <br /> V = volume of wastewater applied to the LAA in millions of <br /> gallons per day <br /> A = area of the LAA irrigated in acres <br /> 8.345 = unit conversion factor <br /> b. The mass of total nitrogen applied to each LAA on an annual basis shall be <br /> calculated using the following formula and compared to published crop <br /> demand for the crops actually grown: <br /> M _ L.(8.345(C V ) + Mx) <br /> i=1 A <br /> Where: M = mass of nitrogen applied to LAA in lbs/ac/yr <br /> Ci = Monthly average concentration of total nitrogen for month i in <br /> mg/L <br /> Vi = volume of wastewater applied to the LAA during calendar month <br /> i in million gallons <br /> A = area of the LAA irrigated in acres <br /> i = the number of the month (e.g., January = 1, February = 2, etc.) <br /> MX = nitrogen mass from other sources (e.g., fertilizer and compost) in <br /> pounds <br /> 8.345 = unit conversion factor <br /> c. The flow-weighted average annual FDS concentration shall be calculated <br /> using the following formula: <br /> 12 aT <br /> [(CPi X VPi) +(Csi X VSm <br /> — 1 <br /> Ca — 12 <br /> (V <br /> gT l <br /> (Vpi + V Si/ <br /> 1 <br />
