Mr. Howard then led us to the hazardous waste treatment areas <br />located outside, at the rear of the facility. Here, Mr. Mora <br />met us and explained the waste treatment systems. There are <br />two major waste treatment systems at this site: <br />1. The batch treatment system. <br />2. The "Continuous side" treatment system. <br />The batch treatment system receives "batches" (55 gallon <br />drums) of waste from the wet processing area, liquid waste <br />from the subfloor of the wet processing area, and occasionally <br />from the maintenance shop. These liquid wastes are then <br />treated through filtration, clarification, precipitation and <br />pH adjustment. The batch treatment process generates specific <br />liquid hazardous wastes, metal sludge and the "decant". The <br />decant is relatively clean liquid which can be transferred to <br />the continuous side treatment system for further processing. <br />The continuous side treatment system is similar to the batch <br />treatment system in that it treats the liquid waste in the <br />same way as the batch treatment system utilizing filtration, <br />clarification, precipitation, and pH adjustment. The <br />continuous side treatment system differs from the batch <br />treatment system in three ways: <br />1. After the waste passes through the treatment process the <br />"cleaned" liquid travels to the City of Stockton's sewer <br />system. This waste discharge is continuously monitored <br />on site, and is permitted through the City of Stockton <br />Municipal Utilities District. <br />2. The continuous side treatment system is much larger than <br />the batch treatment system, and can handle a larger <br />volume of waste. <br />3. Most of the waste received by the continuous side <br />treatment is piped directly into the treatment system. <br />Located next to the batch treatment area, were about thirty 55 <br />gallon drums, seven of these drums were not labeled. Sean <br />Howard told Eric Trevena that these barrels contained <br />hazardous waste. <br />After looking at the waste treatment system. Mr. Howard and <br />Mr. Mora led Mr. Trevena and I to the covered caustic <br />(product) storage area. The eye wash was located here. I <br />asked Mr. Howard how many shifts currently worked on the site. <br />Mr. Howard stated "two", the second shift ending at midnight. <br />I noted that there was no lighting system in the caustic <br />storage area. Alan Ito asked where the nearest communication <br />11 <br />
