RE: Asbestos Containing Material Inspection 13415 S Asher Row Brimley, MI 49715 Parcel ID: Residential Building

Dear Ms. Weist:

Red Cedar Consulting has completed an asbestos-containing material (ACM) inspection at 13415 S Asher Row, Brimley, Michigan (Subject Property). This inspection was completed at the request of the US FWS to comply with the United States Environmental Protection Agency (USEPA) requirements for demolition and renovation set forth under the National Emissions Standards for Hazardous Air Pollutants (NESHAP, 40 CFR Part 61). This inspection was also completed to comply with the Occupational Safety and Health Administration (OSHA) Asbestos Standards for Construction (29 CFR 1926.1101) which limits employee exposure to asbestos.

SUBJECT PROPERTY

The Subject Property is comprised of a residential parcel which contains an approximate 1,200 square foot residential building with attached garage (the Building) with an unknown construction date. The Building was constructed on a concrete basement with one aboveground floor. The exterior walls of the Building were finished with clapboard siding while the roof was sealed with metal roofing. The Building can be further divided into a kitchen/dining room, living room, bathroom and three bedrooms.

VISUAL INSPECTION AND SAMPLING

Asbestos Containing Materials Inspection

Mr. Aaron Paquet of Red Cedar Consulting (Red Cedar), an accredited State Of Michigan/EPA Asbestos Building Inspector (Accreditation Number A30955) whom completed training per the Michigan Asbestos Workers Accreditation Act 440 completed an inspection of the Subject Property on July 19, 2022 for suspected asbestos containing building materials.

This inspection, and subsequent sample collection was completed in accordance with the USEPA Asbestos Hazard Emergency Response Act (AHERA) (40 CFR Part 763) assessment and sampling protocol.

Project No.: 22-1288

US FWS

Parcel ID: 13415 S Asher Row

During the completion of the inspection, each area of the Subject Property was visually inspected for asbestos containing building materials (ACBM). Following the completion of the visual inspection, Red Cedar staff identified each suspect area of friable and non-friable ACBM and sorted them into one of three homogenous categories for sampling purposes. AHERA defines friable as a material that when dry, may be crumbled, pulverized, or reduced to powder by hand pressure. A homogenous area is defined by OSHA as an area of surfacing, thermal system insulation (TSI) or miscellaneous material that is uniform in color and texture. Surfacing materials are most commonly found in sprayed-on, troweled-on or otherwise applied to surfaces, such as acoustical plaster on ceilings and fireproofing materials on structural members. TSI refers to materials applied to pipes, fittings, boilers, ductwork, or other components to prevent heat loss or gain, or condensation. Any material that does not fall under the surfacing or TSI category, such as floor tile, drywall, and acoustical ceiling tile are placed into the miscellaneous materials category.

Following the completion of the visual inspection, Red Cedar staff identified the following materials as suspect ACBM:

· Trim Caulk

· House Concrete

· Exterior Concrete

· 12x12 Vinyl Floor Tile

· Linoleum

· 1x1 Ceiling Tile/Glue Pods

· Drywall & Compound

· Window Glazing

· Stair Tread

· Window Caulk

· Fiberboard

· Light Paper

· Black Line Insulation

Red Cedar staff collected forty-five samples of suspect ACBM separated into fifteen distinct homogenous groups for laboratory analysis. Samples were collected and submitted to APEX Research Inc.

Laboratories (APEX) (Accreditation Number 102118-0) for laboratory analysis. Analysis was completed utilizing polarized light microscopy (PLM) which is the Environmental Protection Agency (EPA) approved method for analysis of bulk materials for asbestos. PLM analysis completed pursuant to method (EPA 600/M4-82-020) identifies asbestos fiber bundles by the visual properties displayed when the sample is treated with various dispersion staining liquids. The laboratory report completed following the sample analysis indicates if asbestos is present, and at what percentage along with a description and percentage of other fibrous and non-fibrous materials and sample color. Chain-of-custody documentation was followed from sample collection through shipping and receiving of the samples at the designated laboratory. The documentation assures that samples will meet the quality assurance/quality control measures defined by AHERA. The laboratory analytical report prepared by APEX for the forty-five samples is included as Attachment A.

INSPECTION RESULTS AND RECOMMENDATIONS

During the completion of the asbestos inspection, forty-five samples of suspect ACM were collected and are documented in Table 1 along with the Red Cedar sample number, description, friability, material type, ACM classification, sample location, material quantity and laboratory analytical results. A Site Diagram was prepared which provides the general building layout and sample locations and is included as Attachment B.

ACM, as defined by the USEPA NESHAP is “any material containing more than 1 percent asbestos as determined using the method specified in appendix E, subpart E, 40 CFR part 763 Section 1, Polarized Light Microscopy”.

Friable ACM is defined by NESHAP as any material containing more than 1 percent asbestos that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. Friable ACM is a concern due the ease of unintentionally disturbing the ACM which may result in “visible emissions” which is known as a Fiber Release Episode.

Non-friable asbestos-containing material is defined as “material containing more than 1 percent asbestos that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. Non-friable ACM’s are separated into Category I and Category II ACM. Category I ACM is any asbestos containing packing’s, gaskets, resilient floor coverings (vinyl floor tile and linoleum are examples of these) and asphalt roofing products. Category II ACM is stated by NESHAP as any material excluding Category I non-friable ACM such as drywall, plaster or fiberboard insulation.

Presumed Asbestos Containing Material

Presumed Asbestos Containing Materials (PACM) are suspect surfacing, TSI and miscellaneous materials found in buildings constructed prior to 1980 which are classified as and due to the age of the structure, are assumed to be ACM and do not require sample collection and analysis. OSHA dictates that PACM may be “rebutted” following a complete inspection pursuant to AHERA protocol.

No PACM was identified during the completion of this inspection. All suspect materials identified were sampled and analyzed for ACM.

Table 2 lists the location, material description, friability, condition, material type (surfacing, thermal or miscellaneous) and approximate quantity of all PACM documented at the Subject Property.

Table 3 provides a summary all ACM documented at the Subject Property which includes the material location, description, and approximate quantity.

Friable ACM’s

A window glazing sample collected from a window in the garage was found to contain up to 1.25% asbestos following analysis. The assessment to quantify the extent of this material identified two windows within the Building that would fall into the same homogenous group. The locations of the windows are listed below:

· Garage (2 window)

Parcel ID: 13415 S Asher Row

Light Backer Paper identified in the Kitchen in conjunction with the lighting system was sampled and found to contain up to 40% asbestos following analysis. The visual assessment to quantify the extent of this material identified this material at the following locations.

· Kitchen (1 Light)

Category I ACM

Two types of resilient floor covering (Tan 12x12 VFT ML and White Mottled Lin. ML) located within the kitchen and bathroom, respectively, were found to contain up to 1.75% Chrysotile asbestos. The assessment to quantify the extent of this material identified approximately 250 sq. ft. of this material within the Building.

Category II ACM

Trim Caulk samples, collected from the Building were found to contain up to 1.5% asbestos following analysis. The assessment to quantify the extent of this material identified approximately 250 lin. ft. of Trim Caulk compound on the Building.

Drywall Compound samples collected from the Building were found to contain up to 1.25% asbestos following analysis. The assessment to quantify the extent of this material identified approximately 3,800

sq. ft. of drywall compound within the Building.

Glue Glue Pod samples collected from the Building were found to contain up to 1.75% asbestos following analysis. The assessment to quantify the extent of this material identified approximately 450

sq. ft. of glue pods within the Building.

Black Line Insulation Wrap samples collected from the Building were found to contain up to 25% asbestos following analysis. The assessment to quantify the extent of this material identified approximately 30 lin. ft. of Line Wrap within the Building.

RECOMMENDATIONS

Asbestos Containing Materials

The materials listed above and identified as ACM should be abated to mitigate any future exposure.

Please note: The location of samples obtained during this inspection were in a random fashion and areas that were not identified during this inspection may be damaged or have become damaged since the inspection was completed. If Category I or Category II friable materials are discovered prior to or during the demolition/renovation process, these materials must be abated prior to commencement of any demolition/renovation activities at the Subject Property.

REGULATORY REQUIREMENTS

A Notification of intent to Renovate/Demolish form must be filed with the Michigan Department of Environmental Quality- Air Quality Division at least 10 working days prior to any renovation or demolition activities at a site.

The Notification of Intent to Renovate/Demolish form must also be completed and submitted to the MIOSHA-Asbestos Program whenever demolition, encapsulation and/or renovation activities at a site involving greater than ten lineal feet and/or fifteen square feet of ACM will be completed.

Regulated asbestos containing materials per NESHAP (40 CFR Part 61) which falls into any of the following categories are ACM’s that must be removed prior to any renovation/demolition activities at the Subject Property.

· Friable asbestos material.

· Category I non-friable ACM that has become friable.

· Category I non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading.

· Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of renovation or demolition operations.

Asbestos abatement should only be performed by a certified asbestos abatement contractor licensed to complete abatement work. The contractor must also follow the standards and requirements set forth per the OSHA Asbestos Standards for Construction (29 CFR 1926.1101) and the USEPA NESHAP (40 CFR Part 61).
