An Environmental Indicator (EI) inspection was conducted in April 2013 to determine whether human exposures to contamination and the migration of contaminated groundwater were under control at the Lyondell facility.
Lyondell has installed 14 monitoring wells to assess groundwater conditions at the facility. Lyondell sampled the wells annually over a four year time period, with the most recent sampling completed in September 2014. The groundwater was analyzed for VOCs, SVOCs, and Resource Conservation and Recovery Act (RCRA) Metals. The results were compared to EPA’s Regional Screening Level (RSL) for tap water. The results indicate that groundwater is not contaminated.
EPA’s review of available information indicates that there are no unaddressed releases of hazardous waste or hazardous constituents from the Facility. Based on that assessment, EPA’s decision on April 19, 2015, is that no further investigation or cleanup is required. EPA has determined that its decision is protective of human health and the environment and that no further corrective action or land use controls are necessary at this time.
