Summary

EPA's Pacific Southwest (Region 9) office proposes to re-authorize the storage facility application submitted by Emerald Transformer Los Angeles LLC, located at 5756 Alba Street, Los Angeles 90058, for the commercial storage of polychlorinated biphenyls (PCBs). Emerald Transformer Los Angeles LLC requests approval to operate a storage facility with a maximum PCB inventory of 7,920 gallons. EPA has authority to issue approvals for commercial storage of PCBs under Section 6(e) of the Toxic Substances Control Act (TSCA) in accordance with the federal regulations at40 CFR 761.65. After reviewing all the information submitted by the facility, EPA finds that all requirements for the operation of a commercial PCB storage facility have been met. The commercial storage of PCBs is allowed on a temporary basis of not more than one year from receipt of the waste at the facility until the waste must be disposed at an approved PCB disposal facility.

PCBs are a group of chemical compounds previously used extensively in the electrical industry that are generally resistant to biodegradation once they enter the environment. At high concentrations, PCBs have been shown to cause liver and kidney damage in humans, usually through direct exposure or ingestion through contaminated seafood. PCBs are suspected carcinogens (Class B). PCBs are normally found in electrical transformers, capacitors, and contaminated soil resulting from spills.

EPA has determined under Section 106 of the National Historic Preservation Act that historic properties will not be affected by the proposed reauthorization.

EPA has determined under Section 7 of the Endangered Species Act that the proposed reauthorization will not affect any listed species or designated critical habitat.
