GAITAN <br />12/30/2020 3:18pm Met with Michael Levitt, Lead for Ancon Environmental. Stated that Ancon GAITAN <br />has been contracted to take over clean up and clean up is expected to take a total <br />of 3-4 hours. He stated they will continue based on visuals and will perform <br />notebook paper test to detect any oily sheen in the soil. Contacted Michelle Henry <br />'Lead Senior REHSI discussed complaint, based on discussion I will remain on <br />site until clean up is completed. Michael took three soil samples one from the <br />northern most point, one from the middle and one from the southernmost point of <br />the approximately 20 foot impact area. He placed each soil sample onto a sheet of <br />notebook paper, left it for 5 minutes. The middle sample resulted in a small oily <br />sheen. He excavated an additional inch of soil from the middle portion of the <br />impact area. He grabbed another soil sample and placed it on to the notebook <br />paper, no oily sheen was left behind after another five minutes. I grabbed a pair of <br />nitrile gloves and grabbed soil from the north, middle and southern portion of <br />impact area. No oily sheen was observed on nitrile gloves, the oily gloves were <br />disposed in one of the five 55-gallon containers. Clean up was determined to be <br />adequately cleaned. <br />An additional five -55gallon drums with soil impacted with transformer oil were <br />generated. Approximately 2-3 inches of additional soil were excavated. <br />In total ten 55-gallon drums with soil impacted with transformer oil were generated <br />from clean up.

He stated the soil was going to be going as <br />non-hazardous waste. I informed him that if the sample results for transformer oil <br />were to come back as hazardous, then he would be transporting waste soil without <br />proper labeling. He understood. <br />Contacted Celia Barajas, Env. Field Scientist and updated her on clean up.
