Dear Mr. Soliz,
I am pleased to offer you this report for work performed at the reference site.
On May 3rd, 2023, Mr. Joshua Johnson with Element Environmental performed dust sampling to
delineate a Major Asbestos Spill at 720 W. Hopkins, Ave. #A, Aspen, CO 81611. This building has
multiple units that are located side by side. They share a common firewall with no openings in
between them. Unit #A has baseboard heat and does not share HVAC systems with the neighboring
unit. These are the findings from the inspection:
At the 720 Hopkins #A site asbestos containing gypsum board systems were damaged/removed
without proper engineering controls on the interior of all three levels and that a major asbestos
spill has occurred. More than 32 sqft has been removed. The initial bulk sampling and testing
was done by Helpers Restoration. They found the surfacing material to be over 1% asbestos and
therefore ACM. The inspection report classified all interior gypsum board systems as being
asbestos containing and in looking at the materials which were demolished, they are consistent
with the inspection; therefore, the spill must be delineated. Joshua Johnson with Element
Environmental met with Anthony from B&E Paint on May 3rd, 2023. He mentioned that they
were from out of state and were unaware of the need for an asbestos test. They removed
various walls for a remodel. The first and second floor had drywall debris sitting on the ground.
The third floor appeared to be the least contaminated. Dust Wipe Samples were taken from this
floor to see if the fibers had traveled throughout the house. Dust sampling utilizing the ASTM
D6480-05 method was used to delineate the spill. The dust sampling consisted of 2 wipe
samples in the following locations:
W1 – Upstairs Windowsill
W2 – Upstairs Heat Register
The samples upstairs were positive. They both came back with high levels of asbestos contamination;
therefore, all of the interior of the unit is included in the major spill and will need to be cleaned by an
abatement contractor. The upstairs would need to be included in the major spill. The following rules
apply to a major asbestos spill:

Major Asbestos Spills
III.T.2. Major Asbestos Spills In the event of an asbestos spill involving greater than the trigger
levels of ACM, the facility owner, facility operator or contractor must:
III.T.2.a. Restrict access to the area and post warning signs to prevent entry to the area by
persons other than those necessary to respond to the incident;
III.T.2.b. Shut off or temporarily modify the air handling system to prevent the distribution of
asbestos fibers to other areas;
III.T.2.c. Spill Delineation
III.T.2.c.(i) Indoor Spill Delineation Unless the entire facility is to be treated as a major asbestos
spill, a Colorado certified Air Monitoring Specialist (AMS) must determine the extent of the spill
area. This may be done using visual examination, air samples, microvacuum dust samples, wipe
samples or a combination thereof. If visible dust or debris is observed, directly related to or
resulting from the known or assumed ACM which created the major asbestos spill, areas where
it is observed must be included in the abatement of the spill.
III.T.2.c.(ii) Outdoor Spill Delineation The AMS must identify the extent of any debris and any
surface contaminated by debris generated by the spill. This may be done using visual
examination, microvacuum dust samples, wipe samples or a combination thereof. If visible dust
or debris is observed, directly related to or resulting from the known or assumed ACM which
created the major asbestos spill, areas where it is observed must be included in the abatement
of the spill.
III.T.2.c.(iii) Samples must be collected and analyzed quantitatively by TEM using the following
methods:
III.T.2.c.(iii)(A) Air samples must be collected and analyzed in accordance with the procedures
specified in 40 C.F.R. Part 763, Appendix A to Subpart E (EPA 2010) “Interim Transmission
Electron Microscopy Analytical Methods.”
III.T.2.c.(iii)(B) Microvacuum samples must be collected and analyzed in accordance with the
procedures specified in the ASTM International Method D5755-09 (Reapproved April 2014),
“Standard Test Method for Microvacuum Sampling and Indirect Analysis of Dust by
Transmission Electron Microscopy for Asbestos Structure Number Surface Loading.” 71
III.T.2.c.(iii)(C) Wipe samples must be collected and analyzed in accordance with the procedures
specified in the ASTM International Method D6480-19 (January 2019), “Standard Test Method
for Wipe Sampling of Surfaces, Indirect Preparation, and Analysis for Asbestos Structure
Number Surface Loading by Transmission Electron Microscopy.”
III.T.2.d. The General Abatement Contractor (GAC) selected to perform the cleanup of the spill
must: III.T.2.d.(i) Submit notification in accordance with subsection III.E. (Notifications) or
subsection III.G. (Permits), whichever is applicable, to the Division for approval. III.T.2.d (ii)
Using certified Workers and Supervisors, in accordance with Section II. (Certification
Requirements), construct a containment in accordance with the following mandatory
subsections, which must be followed in the exact sequence shown:
III.T.2.d.(ii)(A) Construct the decontamination unit in accordance with subsection III.K.
(Decontamination Unit).

ELEMENT ENVIRONMENTAL | B+E 050323 Hopkins
III.T.2.d.(ii)(B) Install critical barriers in accordance with subsection III.I. (Critical Barrier
Installation)
III.T.2.d.(ii)(C) Comply with the requirements of subsection III.J. (Air Cleaning and Negative
Pressure Requirements
) III.T.2.d.(iii) HEPA vacuum then steam clean all carpets, drapes upholstery and other non-
clothing fabrics in the contaminated area or discard these materials in accordance with
subsection
III.R. (Waste Handling) III.T.2.d.(iv) Launder or discard all contaminated clothing in accordance
with subsection
III.R. (Waste Handling) III.T.2.d.(v) HEPA vacuum or wet wipe with clean amended water all hard
surfaces in the contaminated area
III.T.2.d.(vi) Discard all waste in accordance with subsection III.R. (Waste Handling) III.T.2.d.(vii)
Ensure items cleaned as part of the spill response are included in the clearance process.
III.T.2.e. All persons must comply with any other measures, provided in writing by the Division,
which are deemed necessary to protect public health.
If you have any questions about the report, feel free to call Josh Johnson at (970) 274-3139.
