1.0- This was an inspection for suspect ACM (Asbestos Containing Material) for a complete
demolition. Element Environmental conducted an inspection for materials that would be
impacted during the demolition. This inspection was a full inspection for demolition of
the house. If other suspect materials become visible/apparent during demolition or
construction activities, work in that area should be halted and more sampling/testing
must take place, per Colorado regulations. Any suspect materials that were not tested
are to be assumed to contain asbestos.
2.0- A limited bulk sampling of from all suspect materials was conducted in accordance with
Colorado State Requirements. The minimum number of samples per homogenous areas
are as follows:
2.1- Surfacing Materials- <1,000 sq.ft.- Minimum of 3 samples
1,000 sq.ft.- 5,000sq.ft.- Minimum of 5 samples
>5,000 sq.ft. Minimum of 7 samples
2.2- Miscellaneous materials- Minimum of 2 samples
2.3- Thermal Systems Insulation (TSI)- Minimum of 3 samples
3.0- The purpose of the inspection is to identify materials that are homogenous. A
homogeneous area is defined as one which shares suspect material, texture, color,
location, and/or apparent time of construction. The materials are touched to determine
friability. Friable ACM is material that can be crushed or reduced to powder by hand
pressure. The friable materials are segregated into separate homogenous areas. The size
of the sampling area is determined. Samples are taken according to a random numerical
sequence of the subareas, following guidelines per the EPA Pink Book: Asbestos in
Buildings: Simplified Sampling Scheme for Friable Surfacing Materials.
4.0- Josh Johnson, a Colorado Department of Public Health & Environment certified building
inspector, certification number: 18401, performed the inspection. Samples taken were
sent to CEI Labs in Cary, North Carolina. The samples were analyzed by PLM (Polarized
Light Microscopy) analysis. Per the CDPHE Regulation any sample that is found by a lab
to be trace, or <1% asbestos, is considered to be ACM material. This material would still
be a regulated material by CDPHE. The sample must have an additional “point count”
performed to be considered less than 1% and not be regulated by the CDPHE. The lab’s
documents with analyses and findings are found below.
