Hazardous Waste Tank <br /> System Integrity Report <br /> For <br /> HMT Inspection <br /> The Kraft Heinz Company <br /> Stockton CA February 17,2021 <br /> , Page 9 of 34 <br /> 3.0 EVALUATION FOR CCR COMPLIANCE — HAZARDOUS <br /> WASTE TANK <br /> SUMMARY OF CA DTSC EVALUATION PER TITLE 22 CCR, Part 66265.192: <br /> Pursuant to Title 22, §66265.192 of the California Code of Regulations, the following <br /> highlights provide a summary evaluation of the major areas of concern regarding the <br /> aboveground Hazardous Waste Tank under those regulations: <br /> 1. The primary design basis utilized in the construction of this tank is normal <br /> industry practice for vertical aboveground storage tanks on concrete. The <br /> ancillary equipment includes polyvinyl chloride (PVC) piping. <br /> 2. The product in this aboveground storage tank includes process treatment <br /> solutions such as acid waste water, caustic acid, citric acid, and trisodium <br /> phosphate (TSP) used to treat waste water prior to disposal. <br /> 3. Corrosion protection measures directly applicable to the tank and the ancillary <br /> connections involve material resistant to degradation. The walls of the tank that <br /> are in contact with the stored liquid are of polyvinyl chloride (PVC) and <br /> polyethylene materials resistant to corrosion from the process liquids. The <br /> ancillary connections are made of resistant material such as polyvinyl chloride <br /> (PVC) for protection against degradation. These materials continue to be <br /> resistant to the stored liquid based on current condition and age. <br /> 4. The aboveground storage tank and ancillary connections were installed in 2012 <br /> (per client). The tank and connections show no evidence of deterioration at this <br /> time. If properly maintained now and into the future, the tank and connections <br /> should have a remaining useful life of at least 5 years or more based on past <br /> history and current condition. The next inspection interval for the tanks and <br /> connections have been established as 5 years based on the need to verify <br /> continuing integrity of the material in contact with the stored liquid. <br /> 5. Flow into the tank comes through the ancillary connections and is controlled <br /> manually using a pneumatic pump and switches located near the tank and <br /> equipment. The tank and equipment are monitored visually by the service <br /> technicians. This Hazardous Waste Tank is suitable for continued service until <br /> the next inspection cycle. <br /> NDTRPTNE.DOT REV 2 23264941 Hazardous Wast Tank r3(Rev 1).doc 3/16/2021 1:52 PM <br />
