For spent carbon that does not pass quality requirements for reactivation and is hauled for disposal from the <br />Stockton facility. Please provide the last five transport manifests and the hazardous waste determination <br />information for each one. <br />Please find attached the last five transport manifests for the carbon (DS106N) we send for disposal. We <br />only dispose of one spent carbon stream in this manner. The most recent hazardous waste determination <br />analytical is attached. We do not re-evaluate each load from the same source for hazardous waste <br />determination on a per-shipment basis, nor does the landfill require a new determination for every load. <br />You mentioned that spent carbon identified as hazardous through analysis or listing is sent directly to your <br />hazardous waste operations in Kentucky and Pennsylvania. Does Calgon have any facilities in <br />San Joaquin County where the hazardous spent carbon is sent directly to your hazardous waste <br />operations? Does Calgon use hazardous waste transport manifests to ship to waste to Kentucky or <br />Pennsylvania? <br />We do not currently have any hazardous spent customers in San Joaquin County. We do require <br />hazardous waste transporters for any hazardous shipments set to arrive at our TSDF sites. We offer hazardous <br />waste transportation arrangements through a third party, and our employees are trained to confirm that the <br />transporter listed on the hazardous waste manifest has an EPA ID# for verification when a customer provides <br />transportation. <br />From: Backus, Garrett [EFID] <gbackus@sjgov.org> <br />Sent: Tuesday, November 17, 2020 6:22 PM <br />To: Feliciano, Tony <Tony.Feliciano@kuraray.com > <br />Cc: Muro, Claudia [EI-ID] <cmuro@sjgov.org > <br />Subject: RE: Calgon Carbon Corporation (Stockton warehouse) NtA response - hazardous waste determination <br />Hi Tony, <br />I'm working with Claudia Muro regarding the Calgon facility on Eight Mile Road in Stockton. Thank you for the <br />information you've provided to us. <br />We'd like to get more information to get a better picture of the site operations: <br />For spent carbon that passes through the Stockton facility and sent to one of the reactivation plants such as <br />Gila Bend, AZ; please provide the hazardous waste determination information for the last loads coming from <br />five different source companies. We need to know if the spent carbon is hazardous waste when it's stored at <br />the Stockton facility. We also need to know what type of waste water is being treated at the five source <br />companies. <br />For residual water sent to EBMUD or other disposal facilities; provide transport manifests for the last five loads <br />and the corresponding hazardous waste determination for each one. <br />For spent carbon that does not pass quality requirements for reactivation and is hauled for disposal from the <br />Stockton facility. Please provide the last five transport manifests and the hazardous waste determination <br />information for each one. <br />You mentioned that spent carbon identified as hazardous through analysis or listing is sent directly to your <br />hazardous waste operations in Kentucky and Pennsylvania. Does Calgon have any facilities in San Joaquin <br />County where the hazardous spent carbon is sent directly to your hazardous waste operations? Does Calgon <br />use hazardous waste transport manifests to ship to waste to Kentucky or Pennsylvania? <br />Please provide this information by December 4. <br />2
