An employee repairing the damage at the DWP substation on Coldwater Canyon said the chemical PCB (Polychlorinated biphenyl) was found in the residue on the walls of the room where a regulator exploded on April 6th causing major damage and a power outage to approximately 8,700 DWP customers. The employee also says the presence of the substance PCB was unexpected. Smoke was seen coming from the substation after the explosion. Do we need to worry about what residents were possibly exposed to? Why weren’t we notified by DWP or the council office?
DWP Pays Fine, Steps Up PCB Phase-Out : Settlement Resolves EPA Complaint Citing Leakage of Toxic Chemical at 15 Locations
“PCBs–short for polychlorinated biphenyls–are heat-resistant compounds that for decades were added to cooling oil to prevent fires in heavy machinery and electrical-distribution equipment, such as the transformers and capacitors installed on utility poles.
In recent years, the EPA has classified PCBs as a probable human carcinogen and has banned their manufacture.”
“Leaks were found at these six installations in the San Fernando and Santa Clarita valleys: DWP maintenance and storage yards at 6000 Van Nuys Blvd. and 14401 Saticoy St. in Van Nuys; distributing stations at 14320 Aetna St. in Van Nuys and at 4276 Coldwater Canyon Ave. in Studio City; the Sylmar Converter Station at 13201 Sepulveda Blvd. in Sylmar, and the Castaic Power Plant on Templin Highway in Caustic.”
