UNJOAQUIw Environmental Health Department 0UN 1 `Y- Complaint Record Daily Time and Activity Summary from 7/13/2019 to 9/13/2019 for C00050314 located at 17000 E HWY 120 Activity Date Recorded by 08/13/2019 12:47pm Received a page from Yvonne about an ammonia vapor release from PE 2546 DAI 24 min Wine Group 17000 E State Hwy 120 SC 544 Ripon, CA 95366. 12:48pm Called complainant Mark McPherson (209)495-2341 to ask about the ammonia vapor release. They are uncertain about the amount of ammonia that was release, but believe it was a small amount from their jacketed wine tank. The ammonia may have absorbed into the foam of the jacketed wine tank. When they were evacuating the jacket and the tank everything was empty. There were no exposures and the evacuation happened under maintenance. Went to let Haza know I received a page for an ammonia gas release and to know if a complaint should be generated from the information received. I provided Haza with contact information for Mark McPherson. Haza spoke with Mark and let me know that a complaint should be generated. I returned the pink complaint slip to the front counter so that a complaint may be generated. 08/13/2019 SJC EHD received an ammonia release notification from Mark McPherson with PE 2546 SAEED 120 min Franiza Winery located at 17000 E HWY 120, Ripon, CA today around 12:45pm. SC 544 At 12:55pm I called Mark, and told me while they were doing their walk around this morning, they noticed an ammonia odor at Tank#2046. It is believed that the ammonia odor is coming from this jacketed tank. The release was stopped and isolated, ammonia was pumped down, and the tank has been evacuated. There was no evacuation or exposure due to the release. The facility has contacted a contractor to remove the insulation on the tank to determine the point of the release. The facility started the incident investigation, and will calculate how much of an ammonia released to the atmosphere. I discussed the incident with Muni, and Muni asked me to response and issue a notice to abate. At 2pm I left the office to respond to the release. I arrived onsite at 2:30pm and met with Mark. I inspected the tank and took photos. The tank/insulation from outside looked fine, and no sign of insulation damage that could cause the release. I advised Mark to generate Cal OES spill report. I left the site at 3pm and arrived the office at 3:25pm. I issued a notice to abate by email to Mark with corrective actions to submit the incident investigation report to SJC EHD by September 12, 2019. 08/16/2019 Emailed Mark McPherson stating, "Is there any updates in regards the ammonia PE 2546 SAEED 6 min release? Have the contractor came onsite to remove the insulation?" SC 544 08/19/2019 Called Mark McPherson to follow-up on the ammonia release from 08/13/2019. PE 2546 SAEED 6 min Mark told me that they pressured the wine tank with nitrogen to find out the leak , SC 544 and the tank lost the nitrogen within 3 hours, and could not determine the point of the leak. He added that they will start removing the insulation phase by phase to determine the point of the leak. 08/19/2019 1 had to re-enter the complaint info in ECR again to generate the emergency PE 2546 SAEED 60 min response record, and prop 65 because the counter saved the complaint info after SC 007 1 save and override mine. 08/22/2019 Completed the emergency response records, Prop 65, and photo log.
