Converse Consultants (Converse) is pleased to submit the results of the hazardous materials evaluation conducted at the above referenced site on April 21 & 22, 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, CONVERSE CONSULTANTS Duane H. Matters, CEM Senior Geologist/Asbestos and Lead Program Manager

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

Stucco Concrete Masonry Panels Concrete Masonry Block/Grout Pool Lining Pool Deck Ceramic Floor Tile/Grout 12” x 12” Floor Tile with Mastic Remnant Mastic 9” x 9” Floor Tile with Mastic Carpet Mastic Grout on Decorative Stone Fire Brick/Grout Acoustic Ceiling Material Smooth Textured Drywall Ceiling Textured Drywall Joint Compound Roof Mastic Roofing Material Flex Connector

Following the visual portion of the survey, a total of 51 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 six of the materials tested. The materials identified consisted of the following:

Remnant Mastic Remnant Floor Tile 9” x 9” Floor Tile with Mastic Acoustic Ceiling Material Smooth Textured Drywall Ceiling Textured Drywall Joint Compound

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


12-43224-01 NDOT 1801 Loch Lomond Way DHM ii

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 Smooth Textured Drywall Ceiling Textured Drywall

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

Damaged suspect lead-based paint (LBP) was identified and sampled during the course of our investigation and consisted of a white paint located on exterior concrete masonry block. The paint film coating tested did not have concentrations above regulatory action levels as set by Fed-OSHA. Other paint film coatings observed appeared to be intact and in good condition. The levels of lead did not meet the Environmental Protection Agency (EPA) definition of lead-based paint (e.g., > 5,000 parts per million (ppm) of lead) or Fed OSHA trigger levels (e.g, > 600 ppm of lead). Information regarding the suspect ACMs/LBP 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 2 Fluorescent Light Bulbs 1 Light Ballast 1 Compact Fluorescent Light Bulbs 1 HVAC Unit (Refrigerant) 0 Mercury-containing Thermostats


12-43224-01 NDOT 1801 Loch Lomond Way DHM iii

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

HAZARDOUS MATERIALS SURVEY SURVEY

On April 21 & 22, 2015, Converse Consultants (Converse) conducted a visual and sampling survey at the residential structure located at 1801 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 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 51 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 damaged suspect lead-containing paint film coatings in poor condition (loose and/or peeling) at the site. Sampling of loose and/or peeling paint film coatings was conducted to determine lead concentrations and whether the paint film coatings would require stabilization prior to the demolition process. A total of one paint chip sample was collected. LBP sample collection was conducted by removing the peeling/damaged paint film coating with a hand chisel and then uplifting the representative paint layer. The paint was removed as closely as possible to the substrate. Once the sample was collected, it was transferred to a labeled, sealable sample bag. Following collection, the sample was assigned a field sample number and listed on a laboratory submittal form. A summary of this sample is presented on the EMS laboratory submittal form located in Appendix B. All other paint film coatings observed appeared to be intact and in good condition. Our sampling methodology generally followed the “Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing” published by the Department of Housing and Urban Development (HUD) in 1995. ASBESTOS AND LBP SURVEY RESULTS

ASBESTOS

The 51 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. Per regulations, each layer of a sample must be analyzed as a separate material. Due to layering exhibited in the 51 samples, a total of 123 separate analyses were performed on the samples. A summary of the materials sampled and the analytical results is presented in the following table.

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

Acoustic Ceiling Material Appeared typical to:

The interior ceilings in all rooms with acoustic ceiling material

≈ 1,425 SF 5% Chrysotile

Smooth Textured Ceiling Material Appeared typical to:

The interior ceilings in Hall Bathroom, Master Bathroom, and Kitchen

≈ 325 SF 2% Chrysotile

Textured Wallboard Appeared typical to:

The interior walls in all rooms ≈ 5,800 SF 2% Chrysotile

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):

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. LBP The EPA and HUD define LBP as those materials, which contain greater than 1.0 mg/cm2, 0.5%, or 5,000 parts per million (ppm) lead. Fed-OSHA defines LBP as those materials which contain greater than 0.6 mg/cm2 or 600 ppm lead, which consequently triggers their lead regulation requiring training, personal protection equipment, and specific work practices. One damaged suspect LBP was identified and sampled during the course of our investigation and consisted white paint located on exterior concrete masonry block. The paint film coating tested exhibited concentrations below regulatory action levels as set by EPA, HUD and Fed-OSHA.



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

0 Smoke Detectors 2 Fluorescent Light Bulbs 1 Light Ballast 1 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.
