You may use non-liquid materials such as concrete that were contaminated with PCBs $50 ppm provided the materials are decontaminated in accordance with a PCB disposal approval, the decontamination provisions of §761.79, or an applicable PCB spill cleanup policy, or if they meet an applicable decontamination standard in §761.79(b). The decontamination standard for concrete under §761.79(b) is <10 µg/100 cm² and requires that cleanup be initiated within 72 hours of the spill. If the state cleanup met these standards, you may continue to use the concrete. Alternatively, you may comply with the requirements of §761.30(p) for continued use of contaminated porous surfaces.
