Genstar/Westem Stone Products <br /> 8181 West Eleventh St.,Tracy,CA <br /> Project No.W0195.00 <br /> Page 2 <br /> The property is, for the most part, level with no nearby surface waterways (Figure 1). The lot <br /> encompasses approximately 56,000 square feet of which approximately 45,000 feet are available <br /> for discharge (Figure 2). If the water in the Baker tank was sprinkled evenly over the surface <br /> of the site, less than one inch of water would be released over the area. Assuming the <br /> absorptive capacity of the silty/clayey soils that underlie the site to be 25%, and assuming the <br /> current moisture content is 75% of this capacity, then the depth of penetration of the discharged <br /> water is estimated to be less than one foot. Since the depth to groundwater beneath the site is <br /> approximately eight feet, it appears unlikely that surface discharge of the Baker tank water <br /> would degrade groundwater in any way. <br /> On behalf of Western Stone Products we request your permission to dispose of the stored <br /> remediated water on site. Discharge to the ground surface is proposed as the most cost effective <br /> option. <br /> If you have any questions or comments please do not hesitate to contact me at (209) 838-3507. <br /> Respectfully, <br /> RESNA Industries, Inc. <br /> Marcie R.
