New MPCA Soil Reference Values: Several residential soil reference values (RSRVs) for metals were reduced in 2005 including arsenic and copper. This created a lot of problems trying to reach these low cleanup goals for residential cleanups because the concentrations were near background levels. In December 2008, arsenic was increased from 5 mg/kg to 9 mg/kg and copper was increased from 11 mg/kg to 100 mg/kg. New MPCA Guidance Requirements: * A new format for the restrictive covenant or deed restriction was finalized in 2007 through the MPCA Attorney General office. * The MPCA issued a new guidance document on vapor intrusion in September 2008. ASTM has also published a standard: ASTM E2600-08 Standard Practice for Assessment of Vapor Intrusion into Structures on Property Involved in Real Estate Transactions. We are now waiting for the follow-up technical guidance document on vapor intrusion from the MPCA. * The MPCA VIC Program is also working on a soil reuse guidance document. * The MPCA now requires reports to be in hard copy and electronic format.
