TECHNICAL INFORMATION REQUIREMENTS Page 6 of 12 <br /> FOR A REPORT OF WASTE DISCHARGE <br /> treatment capacity; hydraulic capacity of a main lift station, headworks, or other system <br /> element; and demonstrated effluent storage/disposal capacity). <br /> 17.A narrative description of treatment system operation and maintenance procedures to be <br /> employed, including those associated with effluent storage and disposal. <br /> 18. For POTWs, the level of operator certification and staffing; the names and grade levels of all <br /> certified operators, and the hours that the facility is manned. <br /> 19. For privately owned domestic wastewater treatment facilities, the names and grade levels of <br /> all certified operators, and the hours that the facility is manned. If the facility does not have a <br /> certified operator, provide justification for not retaining one. <br /> C. Planned Changes in the Facility and Discharge (for existing facilities only) <br /> 1. Describe in detail any and all planned changes in the facility or discharge, addressing each <br /> of items listed in Section B above. <br /> D. Local and Site-Specific Conditions (Illustrate with maps as appropriate) <br /> 1. Neighboring land uses. <br /> 2. Typical crops grown (if agricultural area). <br /> 3. Irrigation water source(s) and volume and quality data (if agricultural area). <br /> 4. Terrain and site drainage features. <br /> 5. Nearest surface water drainage course. <br /> 6. FEMA floodplain designation(s). <br /> 7. Average Annual precipitation (inches) <br /> 8. 100-year 365-day precipitation (inches) <br /> 9. Reference evapotranspiration (monthly and annual total) <br /> 10. Pan evaporation (monthly and annual total) <br /> 11. A description of the types and depths of soil underlying ponds and/or effluent disposal areas <br /> (include a copy of the geotechnical report and/or NRCS soil report). Include at least the <br /> following: <br /> a. Depth of unsaturated soil when groundwater is closest to the surface. <br /> b. Soil types based on site-specific information, sampling locations (accurately measured <br /> and recorded), description and results of percolation tests or other tests used to <br /> estimate soil long-term infiltration rates. Include depth, thickness, and soil horizons. <br /> Soils must be described at a minimum of five feet below the bottom of any disposal unit. <br /> c. Bedrock type and condition encountered in disposal area, if any. <br /> d. A scaled map depicting soil/rock types and test locations. <br /> 12. Provide the following information about hydrogeology and groundwater: <br /> a. Stratigraphy, groundwater elevation and gradient, transmissivity, and influence of all <br /> recharge and pumping sources site conceptual model). <br /> b. Elevation and gradient of first groundwater at the facility <br /> c. Depth to highest anticipated groundwater based upon onsite measurements taken <br />
