Dear Quetzal Environmental,
I am pleased to offer you this report for work performed at the reference site.
On December 21st, 2017 Mr. Joshua Johnson with Element Environmental performed final clearances at 219 N.
Monarch. The final clearances consist of a visual inspection for dust and debris and ambient air sampling. The
clearance consisted of 2 containments. The main containment was the main house. The ACM drywall and 9x9
tiles were removed. The mini containment was in the ADU bathroom where ACM sheet vinyl was removed.
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 the main work area, and 2 samples were taken from the mini containment.
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.
