| Environmental Matters                                | ENVIRONMENTAL MATTERSIn 2008, a Phase I environmental study and subsequent Phase II environmental study of the University hotel revealed excess levels of certain chemicals in the groundwater on the hotel property that are deemed hazardous.  The Partnership engaged a consultant with respect to the environmental contamination of the University hotel property and to enroll the University hotel property in the Voluntary Investigation and Cleanup (“VIC”) Program of the Minnesota Pollution Control Agency (“MPCA”).  The Partnership's ultimate goal is to obtain a No Further Action Letter determination with a Covenant Not to Sue from MPCA with respect to this environmental issue which will enable the University hotel to be refinanced at better rates and/or ultimately sold without an ongoing environmental problem.  Extensive testing was conducted of all aspects of the University hotel property from 2008 through early 2011 to determine the source of the observed contamination.   It has determined that the source of the solvent contamination appears to be on the northeast corner of the University hotel property.  Active remediation of the northeast corner of the property was recommended to mitigate the vapors and the potential for a continued intrusion condition.   To facilitate a reduction in contaminant concentrations and the receipt of a subsequent No Further Action determination, a Corrective Action Design (CAD) plan was submitted to and approved by the MPCA.  In December of 2011 the installation of a remediation system which incorporates soil vapor extraction, groundwater sparging and air stripping technologies was completed.  The remediation system is monitored and ground water and air samples are tested monthly to determine if risks associated with the contaminants are reduced to an acceptable level.  The Partnership has been informed that the remediation system continues to operate as designed and that significant contaminants have been removed from the site, however, the effect on the groundwater will need to be monitored over a longer period of time. The remediation system will be operated until groundwater concentrations, sub-slab vapor concentrations, and other contaminants concentrations warrant a system shut-down test. At this time it is unknown as to how long the Partnership will be required to continue the operations of the remediation system.  During 2011, the Partnership incurred costs totaling $228,965 for remediation related services.  At December 31, 2012 and 2011, $25,515 and $157,581, respectively, remained payable relating to these costs. |
