1 Investigation Remediation Citation Drive, Suite 100 Compliance Restoration Brighton, MI Mailing Address: P.O. Box 2160 Brighton, MI ASTI Fax: March 20, 2017 Ms. Melinda Milos-Dale Charter Township of Oakland Parks and Recreation 4393 Collins Road Rochester, Michigan RE: Limited Asbestos Survey 3340 East Clarkston Road, Oakland Twp, Michigan (ASTI Project No ) Dear Ms. Milos-Dale: ASTI Environmental (ASTI) was retained by the Charter Township of Oakland Parks and Recreation to conduct a follow-up limited asbestos survey at 3340 East Clarkston Road in Oakland Twp, Michigan (Property). The survey was performed for the benefit of the Charter Township of Oakland Parks and Recreation, and ASTI acknowledges that said parties may rely on the contents and conclusions presented in this letter report. ACM Inspection and Results On March 9, 2017, David Amir of ASTI s Site Redevelopment Services Group conducted further asbestos testing and evaluation of the above referenced Property. The initial asbestos inspection was performed on March 23, The purpose of the additional sampling was to evaluate the Property for potential ACMs prior to demolition of the residence that were not accessible during the initial inspection. The limited ACM inspection was done in accordance with the National Emission Standards for Hazardous Air Pollutants (NESHAP) requirements. Mr. Amir s accreditations (Accreditation No. A16059) are provided as Attachment A. ASTI accessed wall spaces to identify areas where vermiculite attic insulation had fallen into wall spaces. Observations by ASTI identified some minor accumulation of vermiculite within exterior walls in the original front portion of the house. Furthermore, the extent of the vermiculite in the attic included the front original section of the house in the attic. The following additional materials were sampled in the house located at 3340 East Clarkston Road in Oakland Twp, Michigan: Flooring and associated mastics(various types)

2 Kitchen counter board and associated mastic Electrical cloth insulation (various types) Concrete floor Wall material Attic insulation Pipe insulation ASTI collected 20 bulk samples of the suspect ACMs and 23 sample layers were analyzed via PLM analysis. In addition, two samples were analyzed via EPA PLM 400 point count analysis. The bulk samples were transmitted under chain-of-custody protocol to Sanair Technologies Laboratory in Powhatan, Virginia for asbestos analysis using polarized light microscopy with dispersion staining (PLM/DS) in accordance with the US Environmental Protection Agency s (US EPA s) Interim Method for the Determination of Asbestos in Bulk Building Materials (EPA 600/R-93/116), December 1993). Review of the analytical results revealed that none of the additional materials tested were identified as ACMs. The concrete floor (grey) contained asbestos; however, it was less than 1% and is not considered an ACM per NESHAP. However, based on the presence of asbestos, 29 CFR the OSHA Construction Asbestos Standard, applies to demolition activities. The following ACM s were identified by ASTI in the initial inspection: MATERIAL LOCATION ESTIMATED QUANTITY RESULTS Sink undercoat Sink in apartment kitchen 1 sink 10% Chrysotile Drywall mud (wall crack repair) Floor Tile and associated mastic Apartment living room, kitchen, bathroom, rear exit area. (all crack and hole repair compound) All flooring in main house, breezeway, and under layer of the entire apartment 1,200 square feet 2,250 square feet 1.5% Chrysotile (Point Count) 5%-10% Chrysotile (Point Count) According to classification guidelines set forth in NESHAP, the drywall mud is friable, and thus a regulated asbestos-containing material (RACM). The drywall mud in its current condition represents minimal risk of fiber release. However, as demolition activities will disturb the material, ASTI recommends this ACM be removed by a licensed abatement contractor prior to demolition. According to classification guidelines set forth in NESHAP, the floor tiles and associated mastic are classified as Category I non-friable ACMs. These materials in their current condition represent minimal risk of fiber release. As demolition activities are likely to

3 disturb these materials, ASTI recommends the flooring and mastic be removed by a licensed abatement contractor prior to disturbance. According to classification guidelines set forth in NESHAP, the sink undercoat is classified as a Category II non-friable ACM. This material in its current condition represents minimal risk of fiber release. As demolition activities are likely to disturb this material, ASTI recommends the sink be removed by a licensed abatement contractor prior to disturbance. In addition to the above, the following assumed materials were identified by ASTI: MATERIAL Vermiculite LOCATION/DESCRIPTION -Original house attic above 2nd floor and west side of dining room and kitchen -Exterior wall spaces on 1st and 2nd floor of original house -Rear apartment above ceiling ESTIMATED QUANTITY 550 cubic feet Approximately 550 cubic feet of vermiculite insulation was observed in the attic and wall spaces of the Property. Due to the difficulty in obtaining a sample that is representative of this building material, the EPA recommends that all vermiculite be treated as an asbestos-containing material. According to classification guidelines set forth in NESHAP, the vermiculite is friable, and thus, a RACM. Demolition activities will disturb this material and thus removal of this material should be completed by a licensed abatement contractor.
