The Site Remediation Program (SRP) has established residential and non-residential direct contact Soil Remediation Standards (RDCSRS and NRDCSRS) for polychlorinated biphenyls (PCBs) based upon a legislatively mandated 1 X 10-6 cancer end-point. The Residential Direct Contact SRS (RDCSRS) is 0.2 ppm and the Non-residential Direct Contact SRS (NRDCSRS) is 1 ppm.
The USEPA Toxic Substances Control Act (TSCA) does not regulate PCBs at concentrations less than 1 ppm. Above 1 ppm PCBs, TSCA stipulates a range of self-implementing cleanup levels based upon future high and low occupancy scenarios that are identified in 40 CFR 761.61(a)4. Along with some other factors, the disposal requirements for the self-implementing regulatory option vary based on the type of contaminated material and concentration of PCBs in the materials. Responsible party must notify EPA if they are intend to utilize the self-implementing option.
ENVOCARE provides responsible site remediation services, which include the risk-based options. A low-levels of PCBs are found in the historic fill and historical industrial sites. The remediation services include, excavation and disposal of waste containing PCBs, and encapsulating.
