Proposed Cleanup Plan Released for Public Comment - U.S. Liquids City Environmental, Inc., Kansas City, Missouri
EPA Region 7 invites the public to comment on the proposed cleanup plan for the U.S. Liquids City Environmental, Inc. facility at 901 Woodswether Rd. in Kansas City, Mo. The public comment period will start May 1, 2006, and end June 15, 2006. EPA proposes a final cleanup plan for two solid waste management units (SWMUs) and an area of concern (AOC). EPA will hold a public meeting so that community members can ask questions about the proposal.
During the facility investigation, soil samples revealed the presence of volatile organic compounds, lead, and chromium in soil at SWMU 1, SWMU 2, and AOC 1. Total petroleum hydrocarbons (TPHs) were detected in the soil samples at SWMU2. Semi volatile organic compounds were detected in the subsurface soil samples at AOC 1. However, none of these compounds exceeded Missouri Department of Natural Resources (MDNR) cleanup guidelines, with the exception of TPH levels at SWMU 2.
Most of the contaminated soil at SWMU 2 has already been removed and disposed off-site. A limited amount of contaminated soil could not be excavated due to site conditions. Clean soil was used to backfill the excavation. A liner cap was placed over the soil that remained. A 24 inch protective soil layer was placed over the liner cap followed by 6 inches of granular cover. Four cap monuments were installed, and permanent fencing of the site was completed. Also, the facility decontaminated the loading and unloading areas, pumps, hoses and ancillary equipment associated with tank systems, three aboveground tanks, and four process mixing tanks. Also, groundwater samples indicated that groundwater in the vicinity of SWMU 1 and SWMU 2 was contaminated with lead, benzene, ethyl benzene, and naphthalene. Supplemental groundwater investigation conducted at the site confirmed that the groundwater contamination appeared to be limited to the eastern part of the site and is decreasing in concentration.
PROPOSED CLEANUP PLAN
The groundwater at the site is not considered a source of drinking water. Based on this limited usage and the results from the initial site cleanup and investigations, EPA proposes the following cleanup plan:
Interim Measures and Engineering and Institutional Controls
This includes inspection and maintenance of the cap, including observation and surveying of cap elevations and corner monuments. Also, EPA proposes the filling of a deed notice or restrictive covenant and an easement to allow for long-term inspections and maintenance.
Monitored Natural Attenuation
Monitored natural attenuation is the monitoring of natural processes that reduce contaminant concentrations over time to an acceptable cleanup level.
Additional Investigation Activities
EPA proposes groundwater probes near the primary and secondary contaminant plumes at the eastern property line. Also, EPA proposes additional monitoring wells.
This one-acre site was used as a fuel oil depot until 1986. Later, site operations included treatment, storage, and/or disposal of hazardous waste. In 2002, Woodwether LLC purchased the site from U.S. Liquids City Environmental, Inc. All work is addressed under a Resource Conservation and Recovery Act permit. MDNR issued Part I of the permit to address the management and storage of hazardous waste. EPA issued Part II of the permit to address cleanup requirements for the SWMUs and AOC.
