5.4 Alternatives Considered But Rejected as Infeasible <br /> L <br /> Formation, it costs more to process. Deflocculants,or chemicals used to remove clay and make a <br /> material more fluid, have to be used just to remove the clay. Many cycles of processing are often <br /> needed. There is no known instance in which the Laguna Formation is used as an aggregate <br /> material in the Sacramento/San Joaquin County area. The Laguna Formation is used primarily as <br /> a gravel subbase material (building foundations, etc.),but even then presents processing <br /> difficulties due to its clay content. No reports or studies have been published on the Laguna <br /> Formation (Don Depraw, CGS). <br /> r <br /> r <br /> V <br /> V <br /> L <br /> r <br /> r_ <br /> RMC Pacific Vernalis Qua rty Mining and Reclamation Project 5-2t ESA/203015 <br /> Draft Environmental Impact Report May 2006 <br /> r <br />
