PO Box 2043 Glenwood Springs, CO 81602 l970l274-3L39 josh@elementconsults.com Date: 0810312025 Client: Quetzal Environmental Dear Mr. Rudy Alvarado, On August 3'd,2025, at -4:00 pm, Mr. Joshua Johnson with Element Environmental performed final clearances at244Q CO-13, Rifle, CO. The final clearances consist of a visual inspection for dust and debris and ambient air sampling. The final clearance consisted of 1 containment. This was an abatement to remove all of the ACM drywall throughout the house and ACM mortar in the Dining room. Any material or overspray that is remaining must be assumed to be ACM material until it is tested. Mr. Joshua Johnson CDPHE AMS #18401 performed a visual inspection. After the visual inspection was complete, air samples were taken of each of the work areas. Five samples were taken from the work area. The air samples were analyzed by PCM (Phase Contrast Microscopy) per the NIOSH 7400 method. All samples must be below 0.01 f/cc in order to pass the air clearance. All samples were below the limit amount. Per Colorado Reg 8 Part B guidelines. The work area is now clear for occupancy or normal work to resume. Any suspect asbestos containing materials (ACM) remaining should be assumed to contain asbestos unless they are properly tested and analyzed by a CDPHE accredited inspector. All work performed MUST follow appropriate EPA, CDPHE, OSHA, and local government guidelines to protect the employees, occupants, and the environment.
