WASTE DISCHARGE REQ9kEMEMTS ORDER NO. 5-00-142 -4- <br /> CITY OF ESCALON <br /> ESCALON WASTEWATER TREATMENT FACILITY <br /> SAN JOAQUIN COUNTY <br /> 17. A hydraulic analysis of the industrial wastewater portion of the WWTP presented in the <br /> RWD indicates that industrial wastewater flows have reached the WWTP's hydraulic <br /> capacity. Reclamation is not presently performed; however, the Discharger is investigating <br /> reclamation alternatives. <br /> 18. The Discharger is in the process of improving the industrial WWTP. The improvements will <br /> provide more capacity and better treatment. Improvements include deepening the existing <br /> treatment ponds, three new evaporation/percolation ponds (Nos. 20, 22, and 24), piping and <br /> pond configuration improvements, addition of mechanical aerators, and reconfiguration of <br /> existing aerators. Pond No. 22 will provide 5.6 acres of surface area and 5.1 million gallons <br /> of storage capacity. Pond No. 23 will provide 5.0 acres of surface area and 4.7 million <br /> gallons of storage capacity. Pond No. 20 will be constructed as an enlargement of Pond <br /> No. 12; Pond No. 12/20 will provide 4.0 acres of surface area and 11.7 million gallons of <br /> storage capacity.' The construction activities are scheduled to be completed by July 2000, in <br /> time for the beginning of the industrial discharger's processing season. A summary of the <br /> pond configuration improvements is presented below: <br /> Pond Area Pond Volume Hydraulic Capacity <br /> Conditiondwrovement Acres MG MGD MG/year <br /> Existing Conditions 19.5 32.3 2.0 221 <br /> Recommended Improvements <br /> Deepen Treatment Ponds NA 3.1 NR NR <br /> Expand Pond 12 to Incorporate Pond 20 2.2 7.0 0.27 29 <br /> Remove Berm between Ponds 13 and 16 0.3 0.5 0.04 3 <br /> Remove Berm between Ponds 14 and 17 0.3 0.5 0.04 3 <br /> Remove Berm between Ponds 15 and 18 0.3 0.5 0.04 3 <br /> Construct Pond 22 5.6 5.1 0.54 58 <br /> Construct Pond 23 5.0 4.7 0.48 52 <br /> Subtotal of Improvements 13.7 18.3 1.41 148 <br /> Total (Ext. + Rec.

Escalon Premier Brands is in the process of retaining a wastewater engineering firm to <br /> identify means to reduce the BOD concentrations of its wastewater and to investigate <br /> opportunities for recycling of wastewater at the plant. <br /> 20. Three groundwater monitoring wells exist at the facility. The wells are screened in the first <br /> saturated interval and are currently sampled annually. Well W-1 is upgradient of the <br />
