Chapter 10.0<br />
Managing Polychlorinated Biphenyls (PCBs)<br />
10.1 Scope<br />
Most equipment containing PCBs have been removed from JSC, but the remaining equipment<br />
may stay in service for the duration of their useful life, as long as they are managed properly<br />
and are not leaking. The requirements in this chapter are generally associated with facility<br />
modification, reconfiguration, maintenance, demolition, or disposal of these items.<br />
10.2 Background<br />
10.2.1 Chemical Description<br />
Polychlorinated Biphenyls (PCBs) are a class of organic compounds with 1 to 10 chlorine<br />
atoms attached to biphenyl, which is a molecule composed of two benzene rings. PCBs were<br />
widely used for many applications, especially as dielectric fluids in transformers, capacitors,<br />
and coolants. Due to PCB's toxicity and classification as a persistent organic pollutant, PCB<br />
production was banned by the United States Congress in 1979.<br />
10.2.2 Toxic Substances Control Act<br />
PCBs in concentrations at or above 50 parts per million (ppm) are regulated by the federal<br />
Toxic Substances Control Act. PCBs in concentrations below 50 ppm are regulated as<br />
industrial solid waste and controlled by TCEQ, (Chapter 3, Industrial Solid Waste).<br />
10.2.3 PCB Locations<br />
PCBs are most frequently found in electrical equipment (transformers, capacitors, switches,<br />
ballasts), hydraulic elevator fluid, and in some products like paint and caulk that were<br />
manufactured prior to 1980.<br />
10.3 Regulated Processes<br />
10.3.1 Electrical Equipment<br />
a. Employees shall comply with the following requirements regarding any markings or labeling<br />
indicating the PCBs content of any electrical equipment:<br />
(1) Do not remove, paint over, or deface markings or labels in any way; and<br />
(2) Locate markings and labels on the faceplate or directly adjacent to it.<br />
(3) Employees at JSC shall use only electrical equipment or fluids that are documented to<br />
contain less than 1 ppm PCBs.<br />
(4) Employees shall notify the EO prior to the removal of any electrical equipment containing<br />
dielectric fluid in order to verify PCBs status and develop a strategy for ultimate disposition.<br />
