Subject: Hazardous Materials Evaluation 162-04-311-005 1913 Loch Lomond Way Las Vegas, Nevada

Dear Mr. Piekarz:

Converse Consultants (Converse) is pleased to submit the results of the hazardous materials evaluation conducted at the above referenced site on April 20 & 21, 2015. Based on our understanding of the project, our scope of services consisted of a visual inspection, bulk sample collection of suspect asbestos-containing materials (ACMs), laboratory analysis, and the generation of this report. The objective of our evaluation was to identify asbestos which may require remediation in regard to the planned demolition of the structure. Additional hazardous materials identified at the site have also been noted for proper removal/disposal as required. The survey was performed in general accordance with our proposal dated July 18, 2012 and your written authorization to proceed on October 5, 2012.

If you have any questions concerning information contained in this report, please contact us at your convenience.

Respectfully submitted,

EXECUTIVE SUMMARY

The suspect ACMs identified and sampled during the course of our investigation consisted of:

Acoustic Ceiling Material Textured Drywall Ceramic Floor Tile with Grout 12” x 12” Floor Tile with Mastic 9” x 9” Floor Tile with Mastic Remnant Mastic Sheet Flooring Concrete Masonry Unit Block with Grout Fire Brick Stucco Pool Decking Pool Lining Joint Compound Flex Connector Roof Mastic Duct Sealant Asphalt Roofing Shingle with Felt Paper

Following the visual portion of the survey, a total of 48 bulk samples were collected from areas representing the homogeneous use of suspect building materials. Polarized Light Microscopy (PLM) indicated the presence of asbestos in excess of 1% by weight in eight of the materials tested. The materials identified consisted of the following:

Acoustic Ceiling Material Textured Drywall 12” x 12” Floor Tile with Mastic 9” x 9” Floor Tile with Mastic Remnant Mastic Sheet Flooring Joint Compound Roof Mastic

It is the opinion of Converse, based on our understanding of the National Emission Standards for Hazardous Air Pollutants (NESHAP), that the following ACMs will require removal by a certified Nevada licensed abatement contractor in order to comply with Federal, State, and County regulations prior to the demolition process. It may also be

necessary to perform third party air quality sampling after the removal activities to comply with Nevada OSHES and Clark County Department of Air Quality (CCDAQ) regulations.

Acoustic Ceiling Material Textured Wallboard Sheet Flooring

It is the opinion of Converse that with the use of proper engineering controls (i.e. wet methods, perimeter air monitoring, and proper training of the demolition contractor), the approval of Nevada OSHES, CCDAQ, and if no recycling of waste materials is permitted, the following non-friable ACMs may be allowed to stay in place through the demolition process (however if the slabs will be left in place after building demolition any tile and mastic should be removed from the slab before building demolition):

Remnant Mastic 9” x 9” Floor Tile with Mastic 12” x 12” Floor Tile with Mastic Joint Compound Roof Mastic

Information regarding the suspect ACMs sampled/analyzed is provided in the body of our report. Additional hazardous materials that have been identified which will require proper disposal prior to the demolition process consist of the following:

0 Smoke Detectors 3 Fluorescent Light Bulbs 1 Light Ballasts 13 Compact Fluorescent Light Bulbs 1 HVAC Unit (Refrigerant) 0 Mercury-containing Thermostats

All light fixtures must be evaluated for polychlorinated biphenyl (PCB) containing ballasts during the abatement process.

HAZARDOUS MATERIALS SURVEY

SURVEY

On April 20 & 21, 2015, Converse Consultants (Converse) conducted a visual and sampling survey at the residential structure located at 1913 Loch Lomond Way in Las Vegas, Clark County, Nevada. The objective of our evaluation was to identify asbestos and/or damaged lead-containing paint film coatings which may require remediation in regard to the planned demolition of the structure. Additional hazardous materials identified at the site have also been noted for proper removal/disposal as required. The survey was performed in general accordance with our proposal dated July 18, 2012 and your written authorization to proceed on October 15, 2012.

The site consisted of an approximate 1,762 square foot (SF) slab-on grade structure. The structure was used for residential purposes and was reportedly constructed in 1963. Interior walls are drywall, and ceramic tile. The exterior of the building is stucco clad with asphalt shingle roofing with asphaltic mastic. An in-ground pool is located on the subject property.

METHODOLOGY

ASBESTOS

A visual survey was performed to classify each suspect ACM by location and condition in order to establish homogeneous areas for bulk sample collection. Homogeneous areas refer to areas in which similar application, age, and appearance of building materials exist.

Following the visual portion of the survey, a total of 48 bulk samples were collected from areas representing the homogeneous use of suspect ACMs. A summary of these samples regarding each material location and condition is found in the chain of custody documentation in Appendix A.

In general, suspect ACM bulk samples were obtained by (1) adequately wetting the sample area with a water and surfactant mixture and (2) placing bulk pieces of the building materials into labeled plastic bags. Where possible, bulk samples were obtained to the depth of the affected area. Bulk samples were transferred to an analytical laboratory with continuous chain-of-custody documentation.

Our sampling methodology followed the general guidelines for bulk asbestos sampling as presented in Section 40, Part 763 (AHERA) of the Code of Federal Regulations (CFR).



LBP A visual survey was performed to identify any suspect paint film coatings in poor condition (loose and/or peeling) at the site. Loose and/or peeling paint film coatings were not identified during the visual inspection and paint chip sampling was not conducted at the site. ASBESTOS SURVEY RESULTS

ASBESTOS

The 48 bulk samples collected from the Property of suspect homogeneous ACMs were submitted to the Forensic asbestos lab located in Las Vegas, Nevada for analysis by Polarized Light Microscopy (PLM – US EPA Method 600/R-93/116). The Forensic asbestos lab is accredited by the U.S. Department of Commerce, National Institute of Standards and Technology (NIST), under the National Voluntary Laboratory Accreditation Program (NVLAP) for bulk asbestos analysis. Due to layering exhibited in the 48 samples, a total of 129 separate analyses were performed on the samples. A summary of the materials sampled and the analytical results is presented in the following table.

Note: EPA material classifications include: 1) Friable (F), 2) Non-friable (N), and 3) Non-Friable-potentially friable (N-PF) indicating materials which are currently non-friable which may be made friable by standard renovation or demolition techniques. All quantities are estimates and must be field verified by the abatement contractor. 1 – Quantity included in texture referenced for samples 1913-005 to 1913-008.

Photos of samples that were determined to be asbestos containing, analytical reports, and chain of custody documentation are provided in Appendix A.



CONCLUSIONS AND RECOMMENDATIONS ASBESTOS

Current State and Federal standards define an asbestos-containing material as “any material containing asbestos in excess of one percent by weight.” It is noted that Federal OSHA regulates worker exposure to airborne asbestos fibers with Permissible Exposure Limits (PELs) and requires specific work practices and procedures, per 29 CFR1926.1101, when disturbing materials containing asbestos. State of Nevada protects building occupants from airborne asbestos exposure; Clark County Department of Air Quality (CCDAQ) does not allow any airborne asbestos fiber generation. It is the opinion of Converse, based on our understanding of the National Emission Standards for Hazardous Air Pollutants (NESHAP), that the following ACMs will require removal by a certified Nevada licensed abatement contractor in order to comply with Federal, State, and County regulations prior to the demolition process. It may also be necessary to perform third party air quality sampling after the removal activities to comply with Nevada OSHES and CCDAQ regulations.

ACMs to be Abated

Suspect Material Location Quantity % Asbestos

Textured Wall & Ceiling Material Appeared typical to:

The interior walls and non-acoustic ceilings ≈ 5,450 SF 2% Chrysotile

Sheet Flooring Appeared typical to:

Joint Compound Appeared Typical to Garage Walls and Ceilings

≈300 SF 2% Chrysotile

Roof Mastic Appeared typical to: Roof penetrations ≈ 20 SF 7% Chrysotile

Asbestos abatement must be performed by a State of Nevada licensed asbestos abatement contractor using 40-hour asbestos trained workers and appropriate wet methods and engineering controls.

All asbestos abatement workers must have current asbestos training documentation, current medical exams and releases, and current fit tests for the use of personal protective equipment (PPE). The asbestos abatement contractor shall be responsible for estimating and verifying dimensions and quantities of ACMs to be abated. The asbestos abatement contractor shall also be responsible for providing any required notifications in order to comply with CCDAQ and NV-OSHA regulations.

In addition, Converse recommends that asbestos abatement activities be monitored by a NV-OSHA certified third party consultant that will document the asbestos abatement contractor’s use of 40-hour asbestos trained workers, engineering controls and work practices, perform final visual inspections for completeness of the abatement work, perform final air clearance testing for re-occupancy and monitor proper waste handling, transport, and disposal.



ADDITIONAL HAZARDOUS MATERIALS

Additional identified hazardous materials which will require proper disposal prior to the demolition process consist of the following:

0 Smoke Detectors 3 Fluorescent Light Bulbs 1 Light Ballasts 13 Compact Fluorescent Light Bulbs 1 HVAC Unit (Refrigerant) 0 Mercury-containing Thermostats

All light fixtures must be evaluated for PCB containing ballasts during the abatement process for the presence of a “No PCB” label.
