Vapor Intrusion Study Begins, Carter Carburetor Site, St. Louis, Missouri
The U.S. Environmental Protection Agency (EPA) Region 7 will begin a vapor intrusion study at the Carter Carburetor Site, 2000 to 2840 North Spring Street, St. Louis. EPA's Mobile Lab, staffed by EPA contractors, will be on site beginning September 9, 2008 for approximately two weeks.
EPA contractors will collect air samples to determine if trichloroethylene (TCE) vapors are present beneath the floor of the building. This will help EPA determine if there is a potential for these vapors to intrude and accumulate in this building or future buildings. This information will be needed to make decisions as to the type of cleanup that will be needed. Based on the results of this study, additional sampling may be required to determine if vapors are migrating off-site.
The Carter Carburetor Site is a former carburetor manufacturing plant. Gasoline and diesel powered carburetors were made at the site from the 1930s until 1984, when the plant was closed. EPA site investigations found unacceptable levels of polychlorinated biphenyls (PCBs) in the building and some areas outside the buildings.
In 1997 ACF Industries (former owner of Carter Carburetor) conducted a time critical removal action. They demolished and properly disposed of three smaller buildings where PCBs were used in the manufacturing process. EPA has been working with ACF since 2003 to investigate the additional contamination that is under ground and in the larger abandoned building on the site.
CURRENT SITE STATUS
ACF Industries, Inc., the potentially responsible party, is currently performing an Engineering Evaluation/Cost Analysis (EE/CA) under EPA oversight. The EE/CA is a report which evaluates the various cleanup alternatives based primarily on protectiveness and cost. As part of the EE/CA process, ACF discovered TCE contamination in the subsurface. TCE is an industrial degreaser used in the carburetor manufacturing process. TCE can form vapors which can travel through the soil and enter buildings through cracks or other openings in the floor.
