1.0 METHODOLOGY

At home owner’s request, Front Range Environmental conducted a limited scope asbestos survey for the presence of Asbestos Containing Materials (ACM) in the indicated rooms, for possible demolition at the following address: 1701 Centre Ave Fort Collins, Co

Site Visit(s): May 4, 2017

Report Date: May 5, 2017

Field Procedures and Analysis

a. Guidelines used for the asbestos/lead survey and bulk sampling were established by the Environmental Protection Agency (EPA) in order to comply with the Air

Quality Control Commission Regulation No. 8, Part B “Emission Standards for

Asbestos.

b. Field Information in regard to the asbestos survey and bulk sampling was organized as per the AHERA (Asbestos Hazard Emergency Response Act) concept of a homogeneous area. A homogeneous area is defined as a suspect material of similar age, appearance, function and texture. If damage is extensive enough that homogeneous areas cannot be defined, samples will be randomly obtained per functional space. Each material was grouped together as a specific homogeneous Area or obtained from a specific functional space, sampled and then assessed for condition.

c. Bulk samples of suspect ACM (Asbestos Containing Material) and lead were analyzed by Polarized Light Microscopy (PLM) with dispersion staining, as described in 40 CFR Part 763 and the National Emissions Standard for

Hazardous Air Pollutants (NESHAP). Reservoirs Environmental, Inc. was responsible for the analysis of all bulk samples. Reservoirs Environmental is an analytical laboratory accredited for the analysis of Industrial Hygiene and

Environmental matrices by the National Voluntary Laboratory Accreditation

Program (NVLAP), LabCode # 101896.

d. Asbestos survey & bulk sampling will generally begin from the top down of the demo area

e. Sampling is conducted by delineating building materials into homogeneous areas

f. Sampling is randomized based on the area of demolition using a simple grid.

g. Once materials to be sampled are identified they are then classified as friable or non-friable

h. EPA classifies materials as friable or non-friable forms of ACM. Friable materials, are defined by their ability to be crumbled or reduced to powder by hand pressure when dry and in contrast non-friable materials are not able to be reduced to powder by hand pressure. As logic dictates, friable asbestos containing materials have a much higher probability of releasing asbestos containing particulate dust into the air especially when disturbed during renovation and/or demolition activities

i. The EPA breaks non-friable materials into two categories, Category I non-friable materials which are designated in good condition may remain in place during building renovation or demolition provided these materials are not rendered friable during the proposed activities, Category II non-friable materials are required to be removed prior to non-asbestos related building renovation or demolition if there is not a low probability that these materials will remain non-friable during renovation or demolition activities

j. Sampling frequency is compliant with the AHERA rules for frequency and is dependent on friability and classification of the suspect material, friable surfacing materials (less than 1000sqft (3 samples) between 1000-5000sqft (5 samples) and more than 5000sqft (7-9 samples), thermal system insulations at minimum three per homogeneous area although inspector may choose to take more at their discretion and miscellaneous materials have a minimum of 1 sample required, however when over 500sqft of a miscellaneous material is present additional sampling may be employed again at the discretion of the inspector

k. The inspector will clean equipment between each material sample collected to reduce the probability of any cross contamination between samples

l. Bulk samples which are collected are placed in air tight containers and labeled with the appropriate set designation

m. All materials sampled have been slated for demolition. Consequently invasive techniques may have been utilized to obtain or clear areas of suspect ACM.

n. Any materials not tested but mentioned in this report are non-suspect materials

(wood, metal, plastic, rubber or glass)

2.0 SCOPE OF WORK

Survey requested was for specified general areas of the seed research building which included; Designated interior and exterior windows scheduled for replacement—caulking on exterior and interior of sample window

This survey was characterized by a close visual inspection of all accessible proposed demolition areas. All materials sampled have been slated for demolition/impact by the assigned project manager. Selective demolition may have been conducted to access interstitial spaces suspected of containing ACM. Suspect materials have been sampled and inventoried. These suspect systems as well as non-suspect materials which are slated for removal, their corresponding locations and bulk sampling lab results can be found in the following material classification section.

If during the course of demolition or due to a change in scope of affected materials additional suspect building materials not addressed in this survey are slated for disturbance it is recommended additional sampling is conducted or that the suspect building material is assumed asbestos containing and is treated accordingly.

3.0 CONCLUSIONS AND RECOMMENDATIONS:

All samples taken in the designated area for window caulking assessment were “non detect” for asbestos and can be removed by contractor.

Front Range Environmental has made every effort to survey and randomly sample all affected suspect building material associated with this project within the limited scope/budget we were given. However, in some cases hidden or patched in materials may be present which were not readily observed. If during the course of demolition a new type of suspect material not addressed in this survey is discovered due to visual obscurity or change in project scope it is recommended additional inspection and sampling is employed or that this newly discovered material is assumed to be asbestos containing.
