System 140 pounds <br /> <br />SALINITY SOURCE CONTROL <br />21. The Discharger has implemented the following salinity source control measures at the <br />facility: <br />a. Converted from sodium based chemicals to potassium based chemicals where <br />possible. Potassium hydroxide is used for cleaning activities and water softening is <br />performed with potassium chloride. Potassium is preferred because it is a plant <br />nutrient and therefore is more readily taken up by crops than sodium. <br />b. Converted use of chlorinated trisodium phosphate and chlorine bleach to trisodium <br />phosphate. <br />c. Reduced water softener regeneration cycles, thereby reducing the amount of <br />potassium chloride used by 67 percent since 2004. <br />d. Since July 2009, approximately 24,000 gallons per year of the regeneration brine <br />from the water softeners on Bottling Line No. 1 has been captured and disposed of <br />off-site. This represents 60% of the total ion exchange brine. The Discharger has <br />evaluated the potential for off-site disposal of regeneration brine from the remaining <br />water softeners, but determined that, due to their small size and remote locations <br />throughout the facility, off-site disposal would not be cost-effective. <br />e. Eliminated water softening in non-critical areas. <br />f. Implemented use of ozone rather than chemical salts for sanitation in some <br />applications. <br />g. Implemented use of chlorine dioxide in washing tanks and wine processing <br />equipment. Chlorine dioxide is a strong oxidant that is effective at low <br />concentrations. <br />h. Initiated ongoing employee education and training to improve housekeeping <br />practices for storage and clean-up procedures.
