V. MANURE MANAGEMENT PLAN INFORMATION A Manure Management Plan(MMP)was submitted to the EHD Solid Waste Unit under separate cover. This MMP document illustrates nitrogen analysis and nitrogen management of the manures g Y g g that will be produced at the facility and reveals the cropland will readily assimilate the nitrogen provided specific cultural practices referenced in the MMP are implemented and followed. VI. CONCLUSIONS AND RECOMMENDATIONS NLS§ 4.1. The nitrate loading calculations show the effluent from the proposed project will theoretically have an extremely minor nitrate-nitrogen concentration impact to the underlying groundwater due to the land area size of the subject Parcel. Soil analysis demonstrates that planting a grain-type crop over the cropland readily assimilates applied nitrogen fertilizers. NLS§ 4.2, SSS§ 6.7. As the effluent infiltrates into and percolates downward from the soil- effluent interface,the saturated soil conditions will create an anaerobic environment certainly within the tight loam soils, thus promoting denitrification and retarding nitrification. It is recommended these crop types also be grown over the leachfield area to uptake nitrogen from the septic system effluent and harvested as animal feed. Animals cannot be penned or graze within the leachfield area. Groundwater analysis also reveals the effects that close proximity to the Delta has on the underlying groundwater. Given the intense agricultural production in this region for the last several decades,much higher nitrate-nitrogen concentrations should have been observed in the well and water table analyses. This is likely attributed to a dilution effect the Delta has on surrounding groundwater. In addition,the manure from the proposed future animal populations will be easily agronomically absorbed by the cropland provided that a grain-type crop is rotated on the subject Parcel and that the manures are evenly distributed over the cropland,particularly before crop planting. There will be no environmental impact to the subject property from offal and blood from the slaughtered animals since these materials will be captured for processing at Sisk Recycling Company. SSS§ 5.4, 6.8. The soils underlying the proposed leachfield area show a medium permeability. The anticipated domestic wastewater flows from the facility will be extremely minimal. Consequently, the proposed leachfield will easily manage these anticipated flows. The application rate was determined from the perc rate to be 0.643 gallons/ft'/day. The total leachline length is 300 LFLL: 300 x 2 ft2=600 ft2 only accounting for floor area since the leachfield must be built at existing grade. Therefore, the leachlines can mange: 0.643 gallons/ft2/day x 600 ft2 = 386 gpd. Page -8- Chesney Consulting
