1 <br /> V. CONCLUSIONS AND RECOMMENDATIONS <br /> i <br /> NLS§ 4.1. The nitrate loading calculations show the effluent from the proposed project will have a <br /> minimal effect of 4.2 ppm as nitrate-nitrogen on the nitrate loading emanating from the entire <br /> subject parcel of 21.83 acres. <br /> SSS§ 5.4,6.8. The effluent receiving soils underlying the proposed filter bed area show a <br /> relatively rapid permeability considering the soil type; classified as a clay loam. Percolation rates <br /> within this soil type are commonly observed in the Tracy area. Applying the effluent'uniformly by <br /> capping the ends of the two perforated leachline pipes and laying them level, thus forcing the <br /> application of effluent equally over the filter bed area will allow optimum effluent management by <br /> the receiving soils. <br /> NLS§4.2, SSS§ 6.7. No potential problems are predicted from this OWTS. Equal distribution of <br /> effluent will create the best nitrate mitigation environment for effluent treatment by creating j <br /> anaerobic microsites in combination with'the medium organic matter concentration in the soils, <br /> thus theoretically promoting denitrification. This may also reduce the current nitrate-nitrogen soil <br /> concentration of 13 ppm. <br /> The application rate determined from the 18 min/in perc rate was 0.686 gallons/ft2/day. The filter <br /> bed area is to be 450 ft2 of floor area. Therefore,the filter bed can theoretically manage: <br /> 0.686 gallons/ft2/day x 450 ft'= 309 gpd. The ADF was calculated to be 245 gpd. <br /> The septic tank and filter bed area will be barricaded by curbing so that it cannot be driven over or <br /> parked on. <br /> As the engineer-of-record for this portion of the project, I will be working directly with the OWTS <br /> contractor to ensure the system is installed per the above-referenced specifications. <br /> i <br /> i <br /> Pa e -9- <br /> Chesney Consulting <br />
