Item presented for informational purposes.
Background/Discussion
Demolition of the five houses on Main Street and Gates Avenue is complete. Otting House Movers, Inc. has
moved the house at 419 3rd Street. As they prepared to move the house at 406 Main Street,they found some
white powder believed to be vermiculite in the subfloor of the garage.
Staff contacted Techtron Engineering,who tested the powder and determined it was vermiculite and in turn
contacted Hummingbird Engineering to safely dispose of the asbestos.
Otting said the house should be moved in the next couple of weeks, as their buyer would like to be settled in by
the holidays. Once the houses are moved,the HRA has contracted with Veit to remobilize and demo the two
basements.

Mission/Policy/Goal
The goal of the HRA is to improve existing housing stock by offering incentives or programs to repair and
maintain residential properties.

re: Bulk sample asbestos testing results
406 Main Street Northwest
Elk River, MN
Techtron Job No. 14284
Dear Ms. Eddy:
Techtron Engineering, Inc. was retained to perform bulk asbestos sampling and analysis at the
referenced property.
Site work was performed by Andy Turbitt, a Minnesota licensed Asbestos Inspector (See
Appendix I), on October 13, 2020.
Scope of Study
Testing was limited to the vermiculite insulation present in the raised floor cavity of the main
floor front entry room.
Bulk Asbestos Sampling
Bulk samples were collected by wetting the material in question with amended water. A small
portion of this material was then removed and placed directly in a sealed container.
Bulk Asbestos Analysis
Analysis was performed by Techtron Engineering in accordance to EPA methodology. This
method detects asbestos in volumetric concentrations of 1% or greater. Bulk samples were
checked for the following asbestiform minerals: chrysotile, amosite, crocidolite, anthophyllite,
and tremolite-actinolite.
Bulk Sample Results
Three (3) samples were taken from the requested location and analyzed for asbestos. Asbestos
was found in the vermiculite loose-fill insulation present in the raised floor cavity.
Analytical results are located in Appendix II.

Conclusions/Recommendations
At a minimum, the vermiculite insulation should be handled in accordance with OSHA
asbestos rules for materials that contain less than one percent asbestos.
There is no guarantee, implied or otherwise, that all asbestos containing materials have been
identified. If suspect materials are encountered during renovation and/or demolition that have
not been addressed in this report, the materials must not be disturbed until they are positively
identified.
Please call Mike Bodnar at (763) 712-9502 for further assistance.

Test Report: Asbestos Bulk Materials Identification by PLM
Following are the results of material samples obtained for asbestos identification analysis. Samples were
observed at 42X magnification and suspect fibers were isolated from the bulk samples for observation
under polarized light microscopy. The fibers were then evaluated under polarized light microscopy for
extinction angle, sign of elongation, and morphology. Dispersion staining was performed using Cargille
dispersion oils to observe color changes of fibers at various orientations.
Analysis was performed according to EPA method 600/R-93/116. This method has a reporting limit to
<1% asbestos, in volumetric concentrations. Bulk samples were checked for the following types of
asbestiform minerals: chrysotile, amosite, crocidolite, anthophyllite, and tremolite-actinolite.
All sample details and results are listed in the table below.

Laboratory Manager
NAFD = No Asbestos Fibers Detected
NAPS = Not Analyzed Positive Stop
*No asbestos was detected. However, due to the uncertainty with existing testing techniques for vermiculite insulation, EPA and ATSDR
strongly recommend that all vermiculite insulation be assumed to contain asbestos. Therefore, Techtron Engineering recommends that this
material be assumed to contain asbestos in quantities less than one percent.
Reporting Limit: 1%. Some samples reported as NAFD may contain asbestos fibers in quantities below 1%. Detection limits are dependent upon the sample size, matrix, and any
interferences that may be present in the sample. Point counting is recommended for samples that require more precise quantification when samples contain low volumes of asbestos
fibers (i.e. 1-5%). Results are based on field sampling information provided by the client and are only valid for samples tested. Samples are sto red for 30 days unless other
arrangements are made by the client. Samples received in good condition unless otherwise noted. This r eport shall not be reproduced except in full, without the written approval of
