SCS

Michael Greiner is the head of tunnelling at SCS JV.

“This is not uncommon in landfills experiencing elevated temperature conditions where the crews can run into issues such as heavily saturated waste,” said Vidhya Viswanathan, an official with SCS Engineers.

Berkeley’s contractor, SCS Engineers, called for an inspector to walk in long, straight lines across César Chávez with a radioactivity detector.

“A comprehensive surface scan should cover 100 percent of the landfill surface, or as close to that as possible,” White said in the letter to SCS Engineers.

SCS Engineers also recommended that the radioactivity measured at César Chávez be compared to Blair Southern Pacific Landfill, a hazardous waste dump in Richmond that accepted Stauffer’s waste and is fenced off to prevent public access.
