Public Comment for Proposed Remedy and RCRA Permit Termination, The University of Missouri - Columbia, Columbia, Boone County, Missouri


The U.S. Environmental Protection Agency (EPA) Region 7 invites the public to comment on the proposed remedy for the University of Missouri in Columbia, Missouri (University). The public comment period will run from Aug. 14, 2015 through Sept. 28, 2015. EPA and the Missouri Department of Natural Resources (MDNR) also provide notice of intention to terminate the Missouri Hazardous Waste Management Facility (MHWMF) Part I Permit and Hazardous and Solid Waste Amendments (HSWA) Part II Permit.

Written comments on the proposed remedy should be mailed or emailed no later than Sept. 28, 2015, and should be sent to:

A Resource Conservation and Recovery Act (RCRA) Facility Assessment (RFA) was performed by EPA for the University and documented in a report dated Sept. 11, 1990. MDNR issued an MHWMF Part I Permit and EPA issued an HSWA Part II Permit to the University on March 29, 1991. The University identified 57 areas where hazardous wastes were managed (known as solid waste management units or SWMUs). SWMUs are areas where chemicals might have been released to the environment and, therefore, are subject to corrective action under the HSWA Part II Permit. The “Current Human Exposures Under Control” assessment, dated May 21, 2015, provides a summary of analytical data collected during the RCRA Facility Investigation (RFI) at the University. Following review of and/or investigation at each of the 57 SWMUs, only one area was identified as having environmental contamination above acceptable risk-based levels and, therefore, required a remedy. This area is the University Garage (Garage - SWMU 40) located on Champions Drive.


SOIL: Contaminated soil is present under and near the University Garage building.

GROUNDWATER: Contaminated groundwater is present at the University Garage. The University’s domestic water supply comes from a water well located upgradient of the contamination. This supply is monitored and has been verified to be free from contamination.
INDOOR AIR: Chemicals in the soil and groundwater can volatize sufficiently to create an unacceptable exposure in the indoor air of buildings located over a contaminated area. Two buildings that are near the University Garage, General Services Building, and Cliffview Townhomes were tested for indoor air contamination, and EPA determined that indoor air at these buildings was not a concern. The Garage Building has an active ventilation system that was installed in 2006 and continues to operate to address indoor air contamination.

OTHER CONCERNS: A restrictive covenant has been recorded on the Garage property to identify and address the concerns associated with contaminated indoor air and soil. However, there are no restrictions on shallow groundwater use at this property. While contamination was not detected at other SWMUs, four SWMUs [Ashland Road (SWMU 1), Hearnes Center (SWMU 2), Rock Quarry (SWMU 4), and AL Gustin Golf Course (SWMU 44)] were used for land placement of material. The remedy requires that a notice be placed on the property of such activity. At three SWMUs, low levels of chemicals were detected, but below risk-based levels. These include: Hinkson Creek Sheep Burial Site (SWMU 3), Fire Training Area (SWMU 34), and Old MU Gas Station (SWMU 36). Samples could not be collected at two locations: Chemical Waste Storage Building (SWMU 20) and Professional Building UST (SWMU 36).


The proposed remedy for the site consists of the following:


EPA encourages the public to review the Administrative Record and comment on the proposed remedy. Comments or requests should be submitted to the EPA contact on Page 1 by Sept. 28, 2015.

EPA has not planned a public availability session to discuss the proposed remedy. A public hearing has not been scheduled, but will be held if there is sufficient public interest. Requests for a public hearing or public availability session must be made in writing to the EPA contact at the address listed on Page 1, or to Richard Nussbaum, P.E., R.G. at the Missouri Department of Natural Resources, PO Box 176, Jefferson City, MO 65102, and must state the nature of issues to be raised at the hearing. EPA will evaluate any request and hold a formal hearing/availability session if they find that a hearing/session will contribute to the decision-making process by clarifying significant issues affecting the proposed remedy.

EPA will make a final remedy decision only after the public comment period ends and all comments are reviewed. EPA may change the proposed remedy based on any new information and comments from the public. EPA will not terminate the HSWA Part II Permit until all actions required by the final remedy have been completed. MDNR will not terminate the MHWMF Part I Permit until all actions required for closure of regulated units have been conducted.

Individuals may write to the EPA contact on Page 1 to join the mailing list. Joining the mailing list will allow an individual to receive any updated information directly throughout the remedy selection process.
