t <br /> Mr. Doug Stidham 8 February 2000 <br /> t <br /> ADDITIONAL QUESTIONS <br /> Note: Unless otherwise stated, provide requested data for both the industrial and domestic wastewater <br /> systems. <br /> 1) Describe the location of the facility and provide a site map. Also provide a site map which <br /> presents the planned site improvements. Provide a schedule for the construction activities. <br /> 2) Describe the source and volume of the wastewater including seasonal variations. Provide <br /> forecasts on wastewater generation for the next 15 years. <br /> 3) A review of historic data contained in self-monitoring reports indicates that the required <br /> minimum concentration of dissolved oxygen have not been maintained. Describe system <br /> improvements that will prevent future violations. System improvements may include <br /> pretreatment of industrial wastewater prior to disposal. <br /> 4) Review of historic data reveals maximum flow limits have been exceeded. Describe system <br /> improvements that will allow greater flow through the system. Provide a water balance that <br /> presents water storage, flow, rainfall, groundwater infiltration, and freeboard for each month of <br /> the year, for each pond. Show whether the pond system will have sufficient capacity to <br /> accommodate allowable wastewater flow, design seasonal precipitation, seasonal ancillary <br /> inflow, and infiltration during wet season. Design seasonal precipitation shall be based on total <br /> annual precipitation using a return period of 100 years, distributed monthly in accordance with <br /> historical rainfall patterns. <br /> 5) Provide a diagram of the planned wastewater treatment facility. At a minimum provide <br /> diagrams showing pond locations, sizes, aeration devices, piping, valves, and meters. <br /> 6) Provide data on the quality of the domestic water provided to customers served by the WWTP. <br /> 7) Include available data on the depth of groundwater and information on aquifers and aquitards <br /> identified beneath the WWTP property. <br /> 8) Describe any chemical additives or disinfectants added to wastewater to prevent scaling, <br /> biofouling, or other undesirable tendency. Include information provided to the WWTP by the <br /> industrial wastewater dischargers. <br /> 9) Describe the handling and disposal of solids generated by the treatment system. <br /> 10) Provide a water balance which presents the wastewater flow, storage capacity, and pond <br /> level(s). <br /> 11) Is water reclamation being considered for this project? <br /> 12) Describe the surface water drainage patterns. Describe the disposal of stormwater. <br /> C:�Projrct Fila`SiiaEttaloo'Stidhuo020800.doc <br />
