It would be nice to have a figure showing where they collected the samples and a full description of the secondary containment unit (i.e. gravel bottom, full concrete bottom with no seams, cinder -block walls etc...). The photos give a good sense of where the soil was excavated and the location of the tanks, but not the sample locations. Do a believe that the secondary containment bottom also leaked and if so by how much? Could there be floating product under the containment? Even though motor oil is pretty much insoluble, groundwater is very shallow (10-15 feet deep) in this area and we just want to make sure we have no floating product. If the bottom is From: Garrett Backus [EH] [mailto:gbackus@sjcehd.com] Sent: Wednesday, August 22, 2018 9:59 AM To: Meeks, Steven @Waterboards <Steven.Meeks@waterboards.ca.gov> Subject: Profleet Lodi - product petroleum spill Hi Steven, An above ground tank in my jurisdiction (Profleet, 15453 N Thornton Rd, Lodi, CA) spilled 4000 gallons of product motor oil into the secondary containment. Some of the oil seeped through the containment walls laterally. The facility hired Fremouw Environmental to excavate soil around the containment. Confirmation samples were taken and found TPH- diesel of 15 ppm and 275 ppm TPH-motor oil remaining in the ground. The facility had Tim Cook, PE write a justification for closing the site since the residual contamination is below Tier 1 ESLs. I have attached the data. Also Tim Cook requests that a case be opened on Geotracker (something I've never done), so he can upload the report. Can I refer this case to you for evaluation? Thank you, Garrett Backus, Ld.
