On Friday, August 22, 2003 Nowicki & Associates, Inc. (NAI) inspected the rear half of City Hall,
including the council chamber and rear staff area for asbestos containing building materials. The
inspection is considered limited because we confined our examination to the rear portion of the
building, per the City of Yelm's direction. The building is currently occupied and in use. Plans
have been developed to renovate the space and tie it in to the existing library, next door.
Building Description
A fire destroyed much of the front half of the building in the early 1980s. That half was rebuilt and
now houses office and staff areas. City Hall's exterior walls are built of brown brick and mortar.
Those exterior walls are visible in several areas within the rear of the building. The planned
renovations will penetrate the brick exterior walls in one area, in the rear of the staff room. Other
than the one area where the exterior wall will be removed, the building's exterior will not be
disturbed during the planned renovation.
Inside, the building's walls are made of gypsum wallboard and were constructed approximately
two years ago, according to the City of Yelm. Many of the ceilings in the rear half of the building
are made of gypsum wallboard and covered with a heavy popcorn ceiling texture. Other areas
contain a hard ceiling without the texture, or are made of 2x4 foot lay-in ceiling tiles. Throughout
the area, the concrete floors have been covered by either 12x12 inch vinyl tiles or carpet.
Inspection Summary
Asbestos containing materials identified in the building include:
Black mastic which can be found under the gray 12x12 inch vinyl tiles
Popcorn ceiling texture
Suspect materials NAI identified, tested and determined to be non-asbestos containing are:
Brown vinyl cove base molding
Gray 12x12 inch vinyl tiles
Inspection Results
Olympic Regional Clean Air Agency (ORCAA) and Labor & Industries regulations require an
inspection of all buildings greater than 120 square feet for the presence of asbestos containing
materials prior to renovation and demolition. Asbestos containing materials are defined as those
building materials containing one percent or more of asbestos as verified by laboratory analysis.

Asbestos containing materials are sub-divided into three types: surfacing materials, thermal
system insulation, and miscellaneous materials. Surfacing materials are defined as those
materials that are sprayed-on, troweled-on or otherwise applied to surfaces including, but not
limited to, acoustical plaster on ceilings, paints, fireproofing materials on structural members, or
other materials on surfaces for decorative purposes. Thermal system insulation means material
applied to pipes, fittings, boilers, tanks, ducts, or other structural components to prevent heat loss
or gain. All other materials are considered to be miscellaneous materials. All surfacing materials,
thermal system insulation and flooring installed in structures prior to 1980 are assumed to contain
asbestos unless proven otherwise by a licensed building inspector.
Surfacing Materials
Popcorn ceiling texture which can be found in the council chamber and throughout the
hallway in the rear of the building. In total, there are approximately 1100 square feet of the
texture. Laboratory analysis determined that this texture contains 2% Chrysotile asbestos.
Thermal System Insulation
NAI did not detect any suspect thermal system insulation during our inspection.
Miscellaneous Materials
Black mastic, approximately 450 square feel of which can be found under the gray 12x12 inch
vinyl floor tiles in the building's hallway. Laboratory analysis determined that this mastic
contains 5% Chrysotile asbestos.
Brown vinyl cove base molding which can be found throughout the hallway in the rear of the
building. Laboratory analysis determined that this molding does not contain asbestos.
Gray 12x12 inch vinyl floor tiles, of which, approximately 450 square feet can be found in the
building's hallways. Laboratory analysis determined that these floor tiles do not contain
asbestos.
ORCAA regulations require that all asbestos containing materials be properly handled during
demolition and renovation, and that a survey of the asbestos containing materials be provided to
all contractors and posted at the site to prevent potential accidental asbestos exposure.
All asbestos must be removed prior to demolition or renovations in which it will be disturbed.
Contractors are advised that the potential to find asbestos-containing materials including thermal
system insulation in hidden spaces is always present during demolition or renovation projects.
Should suspect materials be discovered during the work, the contractor is advised to call the
author for an inspect/i/oJ1 of the sus material.

Stereoscopic microscopy and polarized light microscopy coupled with dispersion staining is the analytical technique used
.or sample identification. The percentage of each component is visually estimated by volume. These results pertain only
to the samples analyzed. The samples were analyzed as submitted by the client and may not be representative of the larger
naterial in question. Unless notified in writing to return samples, Carolina Environmental, Inc. will discard all bulk samples
after 30 days.
Many vinyl floor tiles have been manufactured using greater than 1 % asbestos. Often the asbestos was milled to a fiber
iize below the detection limit of polarized light microscopy. Therefore, a "None Detected" (ND) reading on vinyl floor tile
does not necessarily exclude the presence of asbestos. Transmission electron microscopy provides a more conclusive
form of analysis for vinyl floor tiles.
I is certified by the signature below that Carolina Environmental, Inc. is accredited by the National Voluntary Accreditation
Program (NVLAP) for the analysis of asbestos in bulk materials. The accredited test method is EPA / 600 / M4-82 / 020 for
fhe analysis of asbestos in building materials. Procedures described in EPA / 600 / R-93 / 116 have been incorporated
Nhere applicable. The detection limit for the method is 0.1 % (trace amount). Carolina Environmental, Inc.'s NVLAP
accreditation number is #101768-0. This report is not to be used to claim product endorsement by NVLAP or any agency
of the U. S. Government. This report and its contents are only valid when reproduced in full. Dust and soil analyses for
asbestos using FILM are not covered under NVLAP accreditation.
