Called and SC 944 spoke to Sayyed who confirmed that the excavation would begin at 9 AM on 9/9/19. Reminded Sayyed to make a Cal OES report today. Sayyed agreed. 5:17 PM - Called to update Muniappa Naidu, CUPA Program Coordinator. 5:18 PM - Steve Bender, Compliance First LLC Regulatory Compliance Inspector, arrived on site. Steve did not know if vacuuming of liquid had occurred already, or if it was going to occur when the excavation (pot hole) is conducted. 5:30 PM -Called Sayyed Ridwan and asked him if any vacuuming of liquid had been conducted yet. Ansered Sayyed's questions regarding reporting the spill incident to Cal OES. Michael Anderson arrived back on site and confirmed that no vacuuming of liquid had been conducted yet. 5:40 PM - Called to update Muniappa. He asked if the water table had been reached due to the auger drilling. I did not know, so Muniappa said to find out on 9/9/19. Left site. 6:12 PM -Arrived home. Received an email chain from Sayyed Ridwan, which included individuals from Ancon Services, Yara North America, and Pacific Boring. In the emails Sayyed Ridwan asked the following questions to Joe Borda,Ancon Excavation Manager: "Another question came up regarding the proposed "hydro-excavation". What happens to the water used for this excavation purpose? Won't it get diluted with the fuel contaminated soil on and around the damaged pipe and cause more issue for the shallow water table in that area?" Joe Borda responded: "Ridwan, Yes the water we use to Hydro Excavate will be contaminated with the fuel spilled , to what degree depends on how much fuel was released. Our Hydro Excavator is equipped with a high power vacuum that will remove the water we use and the contaminated soil as well during excavation. We will then dump all spoils including water into a 20 CY bin for analytical and disposal." Sayyed: "Hi Elianna: Please see email response below from Ancon Services. Is this approach acceptable by you? Upon receiving your confirmation we will proceed." I responded: "Hi Ridwan, Our agency's concerns are if the water used to hydro excavate, once contaminated by the leaked fuel, will reach the water table, given the water table is shallow in the area. Additionally, will the water contaminate much more soil than is already impacted, since the soil may be easily absorbent in the area. We hope you consider these concerns before beginning the work, and understand that we are trying to prevent further contamination of the ground and ground water." Sayyed: "Hi Elianna: We are using six (6) de-watering pumps in that area to constantly keep the water table below the trench depth. That's why when you looked at the pit today it was dry. In other words, we are not anticipating to encounter water table up until the depth of the damaged pipe. Does it help?" I discussed with Muniappa Sayyed's request for approval/disapproval of the hydro excavation scheduled for 9/9/19. Page 1 of 7
