This is a Polarized Light Microscopy Test Report from ORION Environmental Services documenting asbestos analysis results for Mt. Rainier National Park's Camp Mair project. The report, dated January 6, 2026, presents laboratory analysis of eight material samples collected on January 21, 2025, by Mitch Anderson using EPA Method 600/R-98/116. All tested samples—including roofing and sealant materials, tar samples from four wall locations, vinyl sheeting with gray felt backing, spray foam, and insulation—tested non-detect (ND) for asbestos-containing material. Other fibers identified include fiberglass, cellulose, and man-made fibers. The analysis was performed by Ryan Fisher and reviewed by Steven McNeal on January 6, 2026, with a 24-hour turnaround time. Per EPA guidelines, samples will be archived for 30 days before disposal. The Chain of Custody Form indicates samples were relinquished by Mitch Anderson on January 21, 2025, at 3:15 p.m. and received by Now Environmental Services on January 5, 2026, at 10:30 a.m., documenting proper sample handling protocols for the asbestos testing analysis.
