Additional Information Requirements - 2 - <br /> 8. <br /> 2 -8. Projected monthly water balance for each phase of construction demonstrating adequate <br /> containment capacity for the 100-year return period total annual precipitation, including <br /> consideration of at least the following: <br /> a. A minimum of two feet of freeboard in each pond or land disposal area at all times; <br /> b. Historical local evaporation data (monthly average values); <br /> c. Local precipitation data with the 100-year return period annual total distributed monthly <br /> in accordance with mean monthly precipitation patterns; <br /> d. Proposed discharge rates distributed monthly in accordance with expected seasonal <br /> variations; and <br /> e. Projected long-term percolation rates. <br /> 9. A description of measures that will be taken to prevent off-site release of the water. <br /> Site Specific Information <br /> 10. A description of the geology and hydrogeology of the area. <br /> 11. A description of the types of soil underlying the planned disposal areas. Include data on <br /> the depth to groundwater, gradient, and information on aquifers and aquitards identified <br /> beneath the property. <br /> 12. A description of any active or abandoned industrial, agricultural, domestic, or groundwater <br /> wells on the property or the wastewater disposal area(s). If so, provide a map showing <br /> their location(s). If available, a discussion of historical groundwater and surface water <br /> monitoring data (supplemented with tables and maps as appropriate). <br /> 13. Characterization of the quality of the groundwater to be extracted. This may be based on <br /> limited or one-time sampling and must include at least total dissolved solids, nitrate <br /> nitrogen, and any waste constituents that might reasonably be expected to be present <br /> (e.g., fuels from leaking storage tanks). <br /> 14. Characterization of groundwater quality underlying each disposal area. This may be based <br /> on limited or one-time sampling and must include at least total dissolved solids, nitrate <br /> nitrogen, and any waste constituents that might reasonably be expected to be present <br /> (e.g., fuels from leaking storage tanks). <br /> 15. A flood hazard assessment (i.e., are any areas of the site located within the 100 year flood <br /> zone? How are they protected from inundation?) <br />
