There are no crops on the three percolation <br /> fields, but there are eucalyptus and redwood trees on the orchards. The wastewater in <br /> ASB-2 is applied to the LAAs via flood irrigation for disposal by percolation. <br /> Changes in the Discharge <br /> 14. Diamond uses dry ingredients, oils, fats and fresh meat to manufacture 250,000 tons of <br /> pet food each year. Diamond proposed to start manufacture in April 2012 and to <br /> discharge wastewater into the onsite wastewater treatment system, and is currently <br /> operating at approximately 60 percent of production capacity. <br /> 15. With the exception of the wastewater facilities, the paper mill manufacturing facilities have <br /> been removed and restructured for pet food manufacture. Diamond does not propose to <br /> improve the existing wastewater treatment facility. However, the projected wastewater <br /> flow rates and quality are different from the previous paper mill's discharge. <br /> 16. The chemicals used in Diamond's processes and sanitation are listed below. <br /> Annual Usage <br /> Trade Name Hazardous Constituents (gallons) <br /> Trisodium nitrilotriacetate <br /> BJ-55 Nonylphenoxypolyethoxyethanol 200 <br /> Ethylene glycol monobutyl ether <br /> Sodium bisulfate <br /> Nalco 1720 Potassium bisulfate 180 <br /> Cobalt bisulfate <br /> NexGuard 22310 No hazardous ingredients 180 <br />
