On April 10th and April 13th, 2017 Mr. Joshua Johnson with Element Environmental performed final clearances at 415 E. Hyman #401. The final clearances consist of a visual inspection for dust and debris and ambient air sampling. There were 2 containments and 2 clearances. The first containment included the north side of the office, the second containment was of the south side of the office. The removal was of all of the ACM drywall. The only drywall remaining did not have any joint compound or texture on it. The CMU wall had materials on it that were not tested for asbestos. These materials must be assumed that they are asbestos containing, or have them tested prior to disturbing or removal. Mr. Joshua Johnson CDPHE AMS #18401 performed a visual inspection per the CDPHE guidelines and found no visible dirt or debris. After the visual inspection was complete air samples were taken of the work area. Five samples were taken from each of the work areas. Five pumps were ran at 15 LPM. A total of 750 liters were sampled from each pump. The air samples were analyzed by PCM (Phase Contrast Microscopy) per the NIOSH 7400 method. All samples must 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. Please note: 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. _______________________________________________ Joshua Johnson Air Monitoring Specialist# 18401 Received 5/11/17 ELEMENT ENVIRONMENTAL | Rossmore 021617 Received 5/11/17 ELEMENT ENVIRONMENTAL | Rossmore 021617 Received 5/11/17 ELEMENT ENVIRONMENTAL | Rossmore 021617 Received 5/11/17 ELEMENT ENVIRONMENTAL | Rossmore 021617 Received 5/11/17
