Alternate PCB Extraction Methods and Amendments to the PCB Cleanup and Disposal Regulations
The US EPA has issued a proposed polychlorinated biphenyl (PCB) Rulemaking to 40 CFR Part 761. The proposed changes were published in the Federal Register/Vol. 86, No. 202 on Friday, October 22, 2021. US EPA’s proposed rule addresses alternate extraction and determinative PCB methods for use in characterizing and verifying cleanup of PCBs under the federal Toxic Substances Control Act (TSCA). The PCB methods in Part 761 are outdated, and the regulation did not allow use of newer, current methods.
Other proposed changes include amendments to the performance-based disposal option for PCB remediation waste and removing the provision to allow PCB bulk product waste to be used as roadbed material. Additionally, the proposed rule includes provisions for cleanup and disposal of waste generated by spills that occur during emergency situations like floods or hurricanes. Other changes include improvements to the implementation of the regulations, clarifying ambiguity, and correction of technical errors.
Environmental Standards is assisting clients in preparing comments concerning the alternate extraction and determinative PCB methods. Comments were due to US EPA by December 21, 2021; however, an extension to submit comments was announced by US EPA. Comments are now due January 20, 2022.
