The purpose of the survey is to locate and identify potential hazardous materials present within the building, or within close proximity to the building, that may require marking and disposal, or other consideration, before a structure is demolished. A report will be submitted to the SCLBA, identifying and quantifying all hazardous materials for properties assigned to the winning Respondent. Structures should be surveyed for the following materials: • Asbestos containing materials (ACM) (including vermiculite, and in the case of demolition, concrete) • Mechanical and electrical systems containing polychlorinated biphenyls (PCB) • Potentially hazardous or regulated materials/waste located in containers and/or drums • Potential mercury containing equipment During preparation of the survey, a thorough physical inspection should be performed to assess and evaluate the presence of asbestos containing materials at the property. As part of this inspection the following methodology should be used for ACM: 1. A survey should be performed to determine the extent and location of ACM in the survey area. The survey should be qualitative and quantitative in that an attempt should be made to locate accessible friable and non-friable ACM areas, as well as a quantity analysis of the amount of ACM. All accessible areas of the survey should be inspected. 2. Bulk samples of all suspected ACM shall be collected by a Michigan Accredited Asbestos Inspector. Samples shall be collected in a safe manner. As required, limited destructive sampling (ie interior wall or ceiling demolition) should be conducted as part of this assessment in order to gain access to suspected ACM. 3. Per EPA-recommended sampling guidelines, bulk samples shall be collected in each homogeneous area encountered. Homogeneous area is defined as an area of material that is uniform in color, texture, and appearance. 4. Samples of suspect ACM shall be analyzed by an accredited National Voluntary Laboratory Accreditation Program via polarized light microscopy and dispersion staining following the EPA Test Method (EPA-600/M4-82-020) and the National Institute of Standards and Technology Bulk Asbestos Handbook. 5. In an effort to minimize costs, respondents shall utilize first positive stop analysis methodologies.
