As referenced on Page 9, it is our understanding the Quaresma's will sell all of the manure solids <br /> produced at their facility. It has been mathematically demonstrated that there is adequate <br /> cropland to accept all wastewater and manure produced on-site, after the proposed expansion. <br /> An economic analysis should be done to consider applying all manure solids produced at the <br /> dairy to the cropland. If solid in <br /> transfers are made for off-site use, records must be kept of <br /> quantities, destinations and dates. <br /> Because of the shallow groundwater, which can be sampled relatively easily, we do not <br /> recommend monitoring well installation. Baseline nitrate concentrations of the first groundwater <br /> has been established for future reference and can be readily analyzed again in the future, if <br /> needed. <br /> Caution must be used when irrigating the cropland. Since the installation of the new tailwater <br /> return system, tailwater cannot enter any of the canals or ditches near the cropland. Wastewater <br /> will be applied carefully and berms will be created to control the water. The infiltration and <br /> permeability of all nutrient application acreage is comparatively slow and runoff can occur <br /> readily since the cropland will be flood irrigated. <br /> Biomat formation within the leachline trenches will impede percolation to a probable equilibrium <br /> rate of 0.5 gals/sq ft/day. It is important to recognize that all septic systems have lifespans due to <br /> this biomat formation. <br /> This report serves to assess the environmental impact to the soil and underlying groundwater <br /> with respect to nitrate-nitrogen loading. It is our opinion that due to the 1.) substantial <br /> improvements made to nutrient water distribution, 2.)the imported co-gen fly ash, 3.) the on-site <br /> clayey/silty soil structure, 4.) and greater awareness of agronomic balances, will all contribute to <br /> mitigation of nitrate impact. <br /> Although this report does not address other environmental issues such as macronutrient <br /> (phosphorous/potassium) and micronutrient loading, odor, truck traffic or other factors associated <br /> with the farming aspect of the dairy, it is our opinion the dairy is operated under best <br /> management practices to mitigate environmental concerns, and can be expanded due to sufficient <br /> nutrient application acreage. It must be recognized the dairy operates in a predominately <br /> agricultural region where related agricultural operations such as odors, dust, pesticide/nutrient <br /> applications and truck traffic are going to occur. <br /> 11 <br /> Va(ley Ag Research <br />
