=r v <br /> E� <br /> 2.2 Wastewater Application Rate <br /> Wastewater application rates at the site are either 0.2 gpd/ft2 or 0.4 gpd/ft2, depending on <br /> the underlying soil. Soils observed at the site are described below. <br /> E� <br /> .F <br /> 3.0 SITE CONDITIONS <br /> In November 2005, Eco:Logic collected groundwater samples at the Lin Family <br /> ' Properties`and presented the results in a report titled Lin Family Properties--Preliminary <br /> k Groundwater Investigation and Wastewater Facilities Planning Report. Data from that <br /> report was'used to determine the applicability and describe a decentralized wastewater <br /> treatment system option for the Lin Family Properties. f <br /> 3.1 Soils <br /> P. <br /> j <br />{ Soils identified by the United States Department of Agriculture(USDA)National # <br /> Resources'Conservation Service(NRCS)to be located at the site include Capay Clay; <br />} Stomar Clay Loam, and Vernalis Clay Loam [2]. The properties of the soils found at the <br /> site are summarized in Table 1. <br /> Es TABU 1 <br /> i SOIL PROPERTIESa <br /> F LIN FAMILY PROPERTIES <br /> i Effluent <br /> r <br /> Application <br /> i� Acreage, Min K,. , Loading Rate, <br /> Soil ac %of Site inthr d/ft' <br /> Capay Clay 196 48 0.06 0.2 <br /> Stomar Clay Loam 140 34 0.06 0.2 <br /> Vernalis Clay Loam 73 18 0.20 0.4 <br /> ' !From USDA NRCS Web Soil Survey[2]. <br /> b Ifrom the Onsite Wastewater Design Manual [3]. <br /> r <br /> The effluent application loading rate of 0.2 gpd/fe will be used for the Capay Clay- and <br /> Stomar Clay Loam, and 0.4 gpd/ft2 for the Vemalis Clay Loam.
