One of the greatest obstacles to remediating and redeveloping contaminated brownfields properties is the presence of polychlorinated biphenyls, or PCBs, in soil. PCBs are regulated under the U.S. Environmental Protection Agency (EPA) Toxic Substances Control Act (TSCA), and have been since the June 1998 update commonly known as the “Mega-Rule.” Focused on PCB regulations, this update encompassed more than 80 changes and additions to the regulations, including § 761.61 defining “PCB remediation waste” at site cleanups. Within the referenced section, the TSCA clearly defines three remedial options for PCB remediation waste: (1) self-implementing cleanup and disposal; (2) performance-based disposal; and (3) risk-based disposal approval.
