Per Greg, the processed water is a low pH water that contains residual <br />fertilizer products. The release happened after the processed water was <br />conveyed from a lined pond into a temporary aboveground tank. It released when <br />the piping was disconnected. The impacted area is in a secured fenced area and <br />clean-up will not take place today. Greg stated they intend to containerize the <br />impacted soil and profile it for proper disposal. Simplot has not contracted a <br />clean-up company at this time. Updated lead Elena regarding the release. <br />VAN G-LEE 01/25/2022 Generated a complaint record and notice to abate. Emailed the notice to abate to <br />greg.meyer@simplot.com. I contacted Greg Meyer and discussed possible <br />notification needed for CalOES. Greg stated he was unsure if they were going to <br />make one. I received photos of the impacted area via email from Greg. I <br />responded to the email requesting for a map location of the spill because there are <br />multiple parcels at the site address. I also attached a copy of the CalOES spill <br />notification guidance. Completed a photo log for the photos I received from Greg. <br />01/26/2022 I received a map of the spill location from Greg Meyer via email. I contacted Greg <br />to follow-up on their notification to CalOES. Per Greg, they concluded that their <br />release did not meet the criteria of a CalOES notification. Greg stated he will <br />provide me with additional information of how they came to that conclusion. <br />01/27/2022 Completed Prop 65. I received an email from Greg Meyer explaining that the <br />release did not meet the State and Federal requirement of a CalOES notification <br />because "Per the EPA List of Lists (Consolidated List of Chemicals subject to <br />EPCRA, CERCLA, and Section 112(r) of the Clean Air Act), a generic low pH <br />liquid only has an RQ (reportable quantity) if it has a characteristic of corrosivity." <br />Per the email, "Semiannual pH readings from the North Pond (the source of the <br />spill material) from 2016 -2021 indicate an average pH reading of 2.57 with a <br />range from 2.11 —3.95. We do not believe our pond water is corrosive and thus <br />not subject to a RQ." I responded to the email requesting for additional <br />information regarding the processed water's toxicity. <br />VANG-LEE <br />VANG-LEE <br />5105. rpt <br /> Page 1 of 3
