Time Critical Removal Action - Angelica/Penrose Superfund Site, St. Louis, MissouriINTRODUCTION
The U.S. Environmental Protection Agency (EPA) Region 7 will conduct a time critical removal action at the Angelica/Penrose Superfund Site in St. Louis, Missouri from October 24, 2005 through the end of November 2005. The removal will address hazardous substances in drums, compressed gas cylinders, and other containers at the site. It will also include excavation and disposal of contaminated soils from leaking containers.
The Angelica/Penrose Site is located at 120 Angelica Street. It is a large lot that is bordered on the south by Angelica Street and on the north by Penrose Street. It is further located east of Broadway and west of Hall Street. The location is in the northeast part of St. Louis, Missouri, a few blocks west of the Mississippi River.
The site history is unknown. It is in a section of the city’s older industrial/commercial district. There is a solid waste transfer station to the east of the site and a number of abandoned properties in the area. There are a few residences to the west and north of the site. The site is a large open lot occupying roughly one city block and covered with large amounts of trash, waste tires, drums, trailers, other debris, and two buildings.
The St. Louis Land Reutilization Authority holds the property in trust. The Missouri Department of Natural Resources (MDNR) conducted a sampling investigation at the site in April 2005. The purpose of the investigation was to characterize the contents of numerous drums that are present at the site.
Results and observations from the April 2005 sampling effort revealed approximately 83 drums that were scattered throughout the site. The majority of the drums were strewn among the piles of debris. The two buildings at the site also contained numerous drums, but only a few had any contents, as most were determined empty or of minimal contents. There was also a possibility of drums buried within the large debris piles on site. MDNR contacted EPA Region 7 for assistance in conducting a removal action.
CONTAMINANTS OF CONCERN
Contaminants at the site consist of lead, polychlorinated biphenyls (PCBs), ethylene oxide, toluene, xylene and other hazardous substances. There are also pollutants, or contaminants in drums, barrels, tanks or other bulk storage containers that may pose a threat to human health and the environment.
The site is in a mixed residential and/or commercial/industrial area. A few residents live immediately across the street from the site. Operating commercial and industrial businesses also surround the site. Since the site is abandoned, it is subject to trespassing and vandalism. This allows for a significant potential for exposure of people and animals to the hazardous substances found at the site.
EPA is currently investigating and conducting a time critical removal.
Containers at the site will be sampled and will either be separated at
the site or over-packed as necessary. The containers will then be sent
off-site for disposal. Visibly stained and contaminated soils will be
collected with a shovel and placed in a drum for disposal as a hazardous
waste. The majority of the hazardous substances found in the containers
will be sent off for incineration, fuel blending, recycling, or some type
of non-landfill disposal. Empty containers will be crushed and disposed
as solid waste at a landfill. EPA anticipates it will take until the end
of November 2005 to complete this action.
