Dear Sheila:
Kevin Hagen (Al2652), a representative of Angstrom Analytical, Inc., visited the above referenced
property on November 9th, 2011 for the purpose of conducting an asbestos demolition inspection. We are
prepared to state that there are category 1 non - friable asbestos containing building
materials contained in or on the fabric of the structure.
The following materials tested positive for the presence of asbestos:
Mastic residue Sink Undercoating
The non - friable materials are:
Category I:
1. Approximately 140 -150 square feet of asbestos containing mastic residue the kitchen in apt. #1
2. Approximately 1 sink with asbestos containing undercoating in the kitchen in apt. #1
3. Approximately 1 sink with asbestos containing undercoating in the kitchen in apt. #4
No samples other than from the fabric of the building that is planned for demolition were taken or analyzed
and this report relates only to 4647 Tyler St. 120 samples of suspect building materials
were collected and analyzed in our laboratory by Polarized Light Microscopy. Please see attached notes.
During the course of the survey the following hazardous materials were noted:
Mercury Misc, Materials
3 thermostats 10 Smoke det.
Appliances Deteriorated lead base paint was found on:
2 Fridges The front soffit overhang.
4 Stoves
1 Water heater
All friable and category II non- friable materials need to be removed, per applicable regulations, prior to
and demolition efforts. Category I non - friable materials are allowed to be left in place for the demolition.
However, the landfill must be made aware that the demolition debris will contain (minimal amounts of)
category I non - friable asbestos containing material and is subject to the MPCA's rules and regulations
pertinent to the demolition efforts (notifications, etc.). This survey should not be interpreted as a bidding
document or as an asbestos project design. It is incumbent upon the contractor to verify quantities.
Quantification of materials identified in this inspection report are approximations and based on observed
quantities. Additional amounts of material may be present under floor, above ceilings and inside wall
cavities and not fully quantified. For example, thermal system insulation indentified in a basement may
also exist inside wall cavities.
If you have any questions, please call us at the number above.
Sincerely,
,/,,,,/ i

Analysis of Bulk Samples for Asbestos Using Polarized Light Microscopy (PLM)
Sheila Cartney
City of Columbia Heights
590 40th Ave. NE
Columbia Heights
Re: 4647 Tyler St.
Number of Samples: 120
Methods and Definitions
The submitted samples were analyzed using the EPA Interim Method #600/M4 -82 -020
(polarized light microscopy with dispersion staining). The method defines an asbestos containing material
as one that contains grater than 1% asbestos by weight and asbestos is defined as the fibrous forms of serpentine
and certain amphiboles. While the fibrous and non fibrous forms of minerals are discernible microscopically
in hand specimens, the distinction between them is not clear on a microscopic level, especially after processing or
manufacturing. Fibrous amphiboles are generally those whose mean aspect ratios (length over width)
under the microscope are approximately >10; non fibrous amphiboles are generally those whose mean
aspect ratios are approximately <6. During analysis, morphology and an estimate of mean aspect ratio
are used to assign a given mineral fiber population to fibrous and non fibrous categories.
That non fibrous amphiboles are not reported as asbestos is consistent with mineralogical definitions,
but does not imply that non - fibrous amphiboles are not hazardous. Airborne concentrations of them
may be regulated by OSHA under certain circumstances. The type of dispersion staining
used is generally phase contrast, although central stop dispersion staining may also be used.
Percentage Reporting
The percentage of each fiber type present was determined using volume percents
estimated from stereoscopic examination, projected area percents from mounted slide
examination and percents from comparison to weight percent standards. Such estimations are suitable
for most samples, but do have large error ranges. Errors are estimated to be 100 relative percent uncertainty
for percentage estimates under 10% ranging down to as little as 10 relative percent uncertainty for
percentage estimates greater than 50 %. Friable samples which have been estimated by the above methods to
contain less than 10% asbestos can be point- counted, according to the EPA Interim Methods, as required by NESHAPS.
In low percentage samples, point counting may produce false negatives or positives, due to the small number
of points counted. For samples consisting of more than one apparent type of material or layer, the percentage
of each fiber type in each type of material of layer is determined and reported separately; an overall average for the
sample of each fiber type is then calculated. The reported friability of a sample refers to that friability observed in the
condition analyzed (broken, crushed, etc.), and is not to be substituted for an on -site assessment of friability.
Each Angstrom Analytical lab report relates only to the sample tested and may not, due to the sampling process be
representatjve of he material sampled.

Columbia Heights
Dear Sheila:
John Partlow (Al2226), a representative of Angstrom Analytical, Inc., visited the above referenced
property on November 09, 2011 for the purpose of conducting an asbestos demolition inspection. We are
prepared to state that there are category 1 non - friable asbestos containing building
materials contained in or on the fabric of the structure.
The following materials tested positive for the presence of asbestos:
Sink Undercoating
The non - friable materials are:
Category I:
1. Approximately 1 sink with asbestos containing undercoating in the kitchen in apt. #5.
2. Approximately 1 sink with asbestos containing undercoating in the kitchen in apt. #6.
3. Approximately 1 sink with asbestos containing undercoating in the kitchen in apt. #8.
No samples other than from the fabric of the building that is planned for demolition were taken or analyzed
and this report relates only to 4641 Tyler St. NE. 87 samples of suspect building materials
were collected and analyzed in our laboratory by Polarized Light Microscopy. Please see attached notes.
During the course of the survey the following hazardous materials were noted:
Mercury Misc. Materials
3 thermostats 6 smoke detectors
Appliances
1 water heater Deteriorated lead base paint was found on:
4 Boilers The front soffit overhang.
1 Refrigerator
2 stoves
1 A/C unit
All friable and category II non- friable materials need to be removed, per applicable regulations, prior to
and demolition efforts. Category 1 non - friable materials are allowed to be left in place for the demolition.
However, the landfill must be made aware that the demolition debris will contain (minimal amounts of)
category I non - friable asbestos containing material and is subject to the MPCA's rules and regulations
pertinent to the demolition efforts (notifications, etc.). This survey should not be interpreted as a bidding
document or as an asbestos project design. It is incumbent upon the contractor to verify quantities.
Quantification of materials identified in this inspection report are approximations and based on observed
quantities. Additional amounts of material may be present under floor, above ceilings and inside wall
cavities and not fully quantified. For example, thermal system insulation indentified in a basement may
also exist inside wall cavities.
If you have any questions, please call us at the number above.
Sincerely,
John Partlow

Analysis of Bulk Samples for Asbestos Using Polarized Light Microscopy (PLM)
Sheila Cartney
City of Columbia Heights
590 40th Ave. N. E.
Columbia Heights MN 55421
Re: 4641 Tyler St. NE
Number of Samples: 87
Methods and Definitions
The submitted samples were analyzed using the EPA interim Method #600/M4 -82 -020
(polarized light microscopy with dispersion staining). The method defines an asbestos containing material
as one that contains grater than 1% asbestos by weight and asbestos is defined as the fibrous forms of serpentine
and certain amphiboles. While the fibrous and non -fibrous forms of minerals are discernible microscopically
in hand specimens, the distinction between them is not clear on a microscopic level, especially after processing or
manufacturing. Fibrous amphiboles are generally those whose mean aspect ratios (length over width)
under the microscope are approximately >10; non - fibrous amphiboles are generally those whose mean
aspect ratios are approximately <6. During analysis, morphology and an estimate of mean aspect ratio
are used to assign a given mineral fiber population to fibrous and non fibrous categories.
That non -fibrous amphiboles are not reported as asbestos is consistent with mineralogical definitions,
but does not imply that non -fibrous amphiboles are not hazardous. Airborne concentrations of them
may be regulated by OSHA under certain circumstances. The type of dispersion staining
used is generally phase contrast, although central stop dispersion staining may also be used.
Percentage Reporting
The percentage of each fiber type present was determined using volume percents
estimated from stereoscopic examination, projected area percents from mounted slide
examination and percents from comparison to weight percent standards. Such estimations are suitable
for most samples, but do have large error ranges. Errors are estimated to be 100 relative percent uncertainty
for percentage estimates under 10% ranging down to as little as 10 relative percent uncertainty for
percentage estimates greater than 50 %. Friable samples which have been estimated by the above methods to
contain less than 10% asbestos can be point- counted, according to the EPA Interim Methods, as required by NESHAPS.
In low percentage samples, point counting may produce false negatives or positives, due to the small number
of points counted. For samples consisting of more than one apparent type of material or layer, the percentage
of each fiber type in each type of material of layer is determined and reported separately; an overall average for the
sample of each fiber type is then calculated. The reported friability of a sample refers to that friability observed in the
condition analyzed (broken, crushed, etc.), and is not to be substituted for an on -site assessment of friability.
Each Angstrom Analytical lab report relates only to the sample tested and may not, due to the sampling process be
representative of the material sampled.
