Proposed: one (1) debris basin and one (1) lift station Discharge Limits The holding ponds must be designed, constructed, operated, and maintained to control the manure, litter and process wastewater generated during the storage period plus the runoff produced by a 25-year, 24-hour storm event (3.7 inches). The storage period capacity for the open lots must be no less than the greater of the expected average runoff from the month of June or the maximum runoff expected between land application or disposal events. Permit Terms of the Nutrient Management Plan (NMP) 1. Ensure adequate storage of manure, litter, and process wastewater, including procedures to ensure proper operation and maintenance of the storage facilities. 2. Ensure proper management of mortalities. 3. Ensure clean water is diverted. 4. Prevent direct contact of animals with waters of the State. 5. Ensure chemicals and other contaminants are properly handled onsite. 6. Site-specific conservation practices are implemented, including as appropriate, buffers or equivalent practices to control runoff of pollutants to waters of the State. 7. Site-specific setback maps not included in #6 above. 8. Ensure specific records are maintained as required in Part II, Section E, Table A. 9. Implement protocols to land apply manure, litter, and process wastewater to ensure agricultural utilization of the nutrients in the manure, litter, and process wastewater using the narrative rate approach: • Fields available for land application • Timing limitations for land application • Nitrogen & phosphorus transport risk assessment result • Planned crops or other usage • Alternative crops • Realistic annual crop yield goal • Total N & P recommendations per crop • Narrative rate approach methodology, to account for: o Soil test results; o Credits for plant available N in the field; o Amount of N & P in the manure, litter, and process wastewater to be applied; o Consideration of multi-year P application; o Accounting for all other additions of plant available N & P to the field; o Form and source of manure, litter, & process wastewater; o Timing and method of land application; o Volatilization of nitrogen and mineralization of organic nitrogen. • Maximum amount of N & P from all sources 10.
