Stockton Propeller, Inc. - 3 - 10 May 2022 <br /> Order R5-2022-0806 <br /> Generator Inspection (SJCEHD, 2021a and 2021 b). The SJCEHD cited two (2) <br /> Class I violations, and 19 Class II violations, as defined by California Code of <br /> Regulations title 22, section 66260.10 and Health and Safety Code section <br /> 25110.8.5, which relate to the generation, tracking, and disposal of hazardous <br /> wastes. The SJCEHD also observed the waste disposal into the on-Site septic <br /> system via submersible pumps and garden hoses. Mr. Belmont stated that the <br /> Site disposes of Ardrox (penetrant), NuEtch E3 (potassium hydroxide solution), <br /> and DeSmut NS3 (sulfuric and nitric acid) wastewater, as well as spent NuEtch <br /> E3 and Desmut NS3 pure solutions to the on-Site septic system (see photo log <br /> pictures IMG_0490 and IMG_0531; SJCEHD, 2021b). Mr. Belmont also stated <br /> that SPI currently discharges five (5) gallons a day of industrial wastewater to <br /> the septic system (see photo log picture IMG-0653; SJCEHD, 2021 b). <br /> 5. On 27 May 2021 , SJCEHD conducted a Site visit and observed that SPI had <br /> dismantled the pump and garden hose to the on-Site septic system. Instead, SPI <br /> was storing the Site's waste solution in a 55-gallon container while awaiting <br /> laboratory analysis of a sample collected by SPI's Environmental Health and <br /> Safety Manager. SJCEHD issued a Sewage Disposal Notice to Abate directing <br /> SPI to immediately cease disposal of hazardous waste to the septic system <br /> (SJCEHD, 2021c). <br /> 6. On 3 June 2021 , the California Department of Toxic Substances Control <br /> (DTSC) Office of Criminal Investigations (OCI) collected 13 samples to <br /> investigate the potential illegal storage, treatment, and disposal of hazardous <br /> waste by SPI (OCI Case # 15242; DTSC, 2021 a and 2021 b). Several samples <br /> exceeded the California Code of Regulations hazardous thresholds for chemicals, <br /> including six (6) samples that were characterized as toxic, one (1) sample that <br /> exhibited the characteristics of reactivity, and three (3) samples that were <br /> characterized as corrosive. <br /> 7. During the 3 June 2021 DTSC sampling event, Mr. Belmont identified four (4) <br /> containers that he said were normally emptied into the on-Site septic system <br /> (DTSC, 2021 a and 2021 b). Similar to statements made to the SJCEHD, Mr. <br /> Belmont told the DTSC staff that two of these containers were used to store <br /> the rinse water SPI uses after dipping metal plane parts into pure solutions <br /> such as NuEtch E3 (strong base), DeSmut NS3 (strong acid), and Ardrox <br /> (penetrant) solutions, and that after the rinse water barrel gets full, "they pH the <br /> rinse water"' and dispose of it into the septic system. Mr. Belmont claimed that <br /> by mixing the spent solutions of NuEtch E3 and DeSmut NS3 together, the pH of <br /> the strong acid and strong base would be neutralized. Additionally, Mr. Belmont <br /> told the DTSC staff the other two containers disposed of into the septic system are <br /> the spent solutions of NuEtch E3 and DeSmut NS3 (DTSC, 2021 a, pp. 8-9). <br /> 8. The DTSC collected samples from the two (2) rinse containers (sample <br /> numbers SP-03 and SP-10A/B) and from the pure solution containers of <br />
