ARDEN HILLS CITY COUNCIL WORKSESSION - MAY 12, 2008 3 which areas need to be abated before the site can be demolished. She indicated the survey then lists where items can be disposed of and the levels of their contamination. Ms. Gaffin explained that this industry is regulated by the Minnesota Pollution Control Agency, the Minnesota Department of Health, and the EP A with each agency having rules and regulations that govern the procedures of the surveying process. Councilmember Holden questioned how the decision was made to abate certain contaminants and dispose of others. Mr~ Gebhard explained that this is why the developer was working with State certified professionals. He indicated samples were tested and during the demolition trained certified abatement teams will be onsite to handle any areas of concern. Ms. Gaffin added that the professionals used to complete the surveys were all State certified contractors with the appropriate training to decipher between the different levels of contamination. Mayor Harpstead indicated concern with this process for the future residents/businesses that will reside on this property. He asked what contaminants were present on the property and how they might affect the design of the master development plan and the well being of the residents. Mr. Gebhard indicated the asbestos abatement would rid the building and building pads of contamination identified in the surveys prior to future development of the master plan. He didn't see these contaminants as impeding the development. Mr. Gebhard explained that the contamination just needed to be abated properly and in a safe manner so as not to create further problems. Councilmember Holden asked what the procedure would be if contaminants were discovered below the slabs. She questioned if this is outside the scope of this survey. Ms. Gaffin explained there was a contingency for unforeseen asbestos in the buildings that were being demolished. She indicated that asbestos found at other places on the property (within the soil) was not a part of this assessment. Mr. Gebhard indicated that the concrete block walls were sampled along with the slab floors but it was not feasible to sample all of the voids inside these features. He stated surprises in this area were accounted for by contingencies. Ms. Gaffin noted there would be additional phases of investigation where soil borings would be taken. She indicated this survey was focused on the existing buildings and what would need to be done to safely demolish and remove them from the site. Mayor Harpstead questioned how many buried pipes were known about at this site and asked when these issues would be addressed.
