ADDITIONAL INFORMATION REQUIREMENTS • FOR REPORT OF WASTE DISCHARGE 3 CITY OF RIPON • Soil incorporation practices; • Vegetation grown; • Runoff controls, if any; and • Public access controls. 13. A description of the types of soil underlying the planned ponds and effluent disposal areas (include a copy of the geotechnical report). 14. If available, a discussion historical surface water monitoring data (supplemented with tables and maps as appropriate). 15. Projected monthly water balance for each phase of buildout demonstrating adequate containment capacity for the 100-year return period total annual precipitation, including consideration of at least the following. a. A minimum of two feet of freeboard in each pond at all times; b. Historical local evaporation data(monthly average values); c. Local precipitation data with the 100-year return period annual total distributed monthly in accordance with mean monthly precipitation patterns; d. Proposed wastewater loading rates distributed monthly in accordance with expected seasonal variations; e. Projected long-term percolation rates (including consideration of percolation from unlined ponds and the effects of solids plugging on all ponds); and f. Projected irrigation usage rates (if recycling is proposed). 16. Proposed flow limits and basis for the limit for the current facility and each phase of the planned expansion. Consider dry weather flows vs. peak flows and seasonal variations associated with major industrial dischargers. Include the technical basis for the proposed flow limit (e.g., design treatment capacity; hydraulic capacity of a main lift station, headworks, or other system element; and demonstrated effluent disposal capacity). 17. A narrative description of plant operation and maintenance procedures to be employed, including those associated with effluent storage and disposal. 18. A description of any policies or facility design features that reduce the potential for groundwater degradation(best practicable treatment and control or BPTC measures). Such features might include industrial discharger effluent quality limits, prohibitions on discharge of certain types of waste, advanced treatment, disinfection, concrete treatment structures, and pond lining systems. 19. Provide a technical report prepared by a Registered Geologist that provides an assessment of the following: a. Groundwater degradation, if any, that has resulted from the existing operation; and
