VCSTAR: now reporting the two injured people are being treated for contamination at VCMC from an "unknown substance". Officials plan to close the road to contain risk of contamination spreading.
As of now, the actual type of material that was spilled is unknown.
Two, Class II waste facilities are located on Mission Rock road, Santa Clara WAste (Green Compass) Water (SCWW) and Anterra - only admin offices for ANterra are located on Mission Rock Road. SCWW treats and disposes of oil field waste, and other hazardous materials. Vacuum trucks are used to transport hazardous waste from many industries including oil field waste.
VCStar has confirmed 1000 gallons of the substance has spilled in the road way. While they report the driver said probably sewage that will need to be confirmed and drivers of these trucks are generally required to carry an MSDS sheet reporting what substances are carried in the truck so the waste facility can properly dispose of it.
