The committee considered the small amounts of PCBs that are suspected to be present in rocket motors and concluded that these amounts are far too small to pose an environmental concern. No data on PCBs were provided in any of the tests that the committee evaluated. Any small amounts of PCBs that may be present from rockets treated would end up in one of the solid waste streams and be at a concentration well below regulatory limits.
