EPA has proposed revisions to its 2008 Definition of Solid Waste, which excludes “hazardous secondary materials” from regulation under RCRA if they were reclaimed or recycled. The proposed rule would remove the exclusion for hazardous secondary materials sent to a third-party recycler and make them subject to RCRA regulation under Subtitle C, including hazardous waste manifest and storage permit requirements. It would retain an exclusion for facilities that recycle hazardous secondary materials on site or within the same company, but would add notification and storage requirements. The proposed rule would also require all hazardous waste recycling to meet federal recycling standards and include a petition process for facility owners to demonstrate legitimacy. Additionally, eighteen high-value solvents that are remanufactured into similar high-value commercial products are excluded under the proposal from hazardous waste requirements. EPA will accept comments on the proposed rule for 60 days after it is published in the Federal Register.
