The Environmental Protection Agency (EPA) and its contractors demobilized from the Waymire Drum Vapor Intrusion Site (Site) at 7702 Maie Avenue in Los Angeles, California, on March 17^th, 2020. Twelve vapor intrusion mitigation system were installed at the Site in commercial and residential locations where indoor air concentrations of Trichloroethylene (TCE) exceeded EPA's regional screening levels. EPA and contractors will be returning to the site several times throughout the summer and fall to conduct quarterly air monitoring at commercial and residential locations to ensure mitigation measures remain protective of human health.

THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY (EPA) ANNOUNCES THE AVALIABILITY OF THE ADMINISTRATIVE RECORD FOR THE WAYMIRE DRUM VAPOR INTRUSION SITE

In August of 2019, the EPA was requested by the Los Angeles Regional Water Quality Control Board to conduct a removal action at the Waymire Drum Vapor Intrusion site (site) at 7702 Maie Ave in Los Angeles, California. The soil at the site is contaminated with the chemicals commonly used in industrial-cleaning processes: tetrachloroethene (PCE), trichloroethene (TCE) and vinyl chloride (VC). It is unclear how the soil became contaminated but, beginning in the 1920s the site was used as a drum-cleaning facility and later as various auto body salvaging companies. These contaminants can migrate as a vapor from the soil into the indoor air of buildings, posing a threat to public health. This is known as ‘vapor intrusion’. In September 2019, EPA began installing vapor intrusion mitigation systems in affected residential and commercial buildings surrounding the 7702 Maie avenue property.

The Administrative Record contains all documents upon which the EPA has based it decision to conduct a removal action at the site. Copies of the Administrative Record are available at response.epa.gov/waymire and at the following location:
