This document is an asbestos Polarized Light Microscopy (PLM) Analysis Report issued by Schneider Laboratories Global, Inc. for a project at 811 Lamoraux Drive in Sausalito, CA. The analysis was conducted for Advantage Environmental on six bulk samples collected on March 16, 2023, under Order #509433, with testing completed on March 21, 2023. The laboratory analyzed two distinct types of materials: - **Tar Felt Paper (Samples 031623-1 through 031623-4):** Each sample consisted of two layers (a black, bituminous tar layer and a black, fibrous/bituminous felt paper layer). No asbestos was detected in any of these samples. - **Wet Patch Material (Samples 031623-5 and 031623-6):** These samples were gray/black, soft, and bituminous. Analysts were unable to separate individual layers. Both samples tested positive for asbestos, containing 10% Chrysotile, which exceeds the EPA regulatory limit of 1%. In total, 10 layers were analyzed. The report notes that NESHAP recommends verifying friable samples with less than 10% asbestos using Point Count or TEM analysis, and that the EPA recommends treating all attic loose-fill vermiculite as asbestos-containing material. This hazardous material data is critical for ensuring environmental safety, regulatory compliance, and proper abatement planning during facility renovation or demolition projects.
