Concentrate processing environmental protection regulations

The vendor claims that asphalt emulsion stabilization can treat soils with up to 60,000 parts per million (ppm) total petroleum hydrocarbons (TPH). In New York and New Jersey, permitting of the asphalt emulsion process is not allowed for sites where TPH levels are above 30,000 ppm. U.S. Environmental Protection Agency (EPA) regulations allow for the technology to be applied to soils with polychlorinated biphenyl (PCB) concentrations of 10 ppm for controlled-access sites and 25 ppm for uncontrolled-access sites. 

Caution These processes may generate hazardous concentrations of toxic gases or liquids. Appropriate engineering controls to protect personnel and the environment must be used. Wastes generated from these processes may be hazardous and, therefore, need to be managed in accordance with appropriate federal, state, provincial and local environmental regulations.
