Job Number Site Location 40-21-00606 Wilbur Ellis-11701 West Woodbridge Dr. Lodi, CA 95242 POMO/Authorization A21032602 Weather PROJECT TIMELINE & NOTES Time Notes 15:00 Received a call regarding a 5000-6000 gallon spill of Urea Ammonium Nitrate (UN-32)at the above referenced address. Local office was dispatched. 17:00 Crew arrived on site. Initial photos were received. Per site supervisor, product impacted a large area of soil as well as two (2) storm drains. Environmental Health, San Joaquin County Emergency Management and Fish/Game are all en route to location for a site meeting to discuss what each of their requirements will be for cleanup. 17:43 Site supervisor completed site assessment with County Emergency Management, Fish and Game, Wes with Wilbur Ellis and Trevor Carlson with Del Rio Partners. After site assessment was complete, all parties gathered for a meeting to discuss a plan of action. 17:20 Site meeting was concluded. It was advised that Fish/Game did not see an Environmental impact at this time due to the product normally PHing neutral at a 6.0-6.5 and being water soluble; meaning if any product did reach the Meckaloma River, it would be dispersed upon contact. However, they would consult with their Emergency Management Team to see if additional steps will be needed. San Joaquin County Emergency Management agreed with Fish and Game. Since product is non-regulated and non- hazardous, the Environmental impact is minimum. However, due to the large amount that was absorbed into the soil, they are requesting a remediation of the contaminated soil to be performed. They also request that both storm drains be flushed and all liquid be collected and removed via a vacuum truck. 20:15 Crew then took measurements of the contaminated area for future remediation purposes. It was determined there is approximately 935 cubic yards of contaminated soil which will be removed during soil excavation and replaced with clean backfill. Crew then took soil and water samples. A sample of virgin product was also taken so the lab would have a comparison sample. Samples will be mobilized to the lab with a rushed result request as requested by Mark Verr with the CA State Water Board. Due to the cost of the rushed requested sampling, Wes Serpa with Wilbur Ellis was called and consulted with. Wes agreed rushed results are necessary and approved the rushed sampling request. 20:30 Storm drain outfalls were plugged out of an abundance of caution to ensure no additional product could impacted the storm drains or canals. Supervisor then collected all names, phone numbers and email addresses of all local county and state government agencies on site for future correspondence regarding this release. All collected contact information was then provided to the PM. As requested by Trevor Carlson with the property owner, Del Rio Partners a cost estimate and scope of work plan will be created and sent to him for approval prior to scheduling or beginning the onsite soil remediation or storm drain clean out. PM will have the local remediation PM to complete a site visit on Monday 29 March 2021 to verify all previously provided information to ensure an accurate cost estimate and scope of work plan is created and disbursed for approval prior to scheduling remediation. 21:00 Crew departed site. Remediation to be scheduled at this location once all permissions and approvals are received and scope of work plan is approved by the property owner, the Wilbur Ellis Company as well as all state and local officials. Further action needed pending approvals. 890 a 7 f3 f-e8e6-4eO8-be 5e-d 647733963a2
