Dear Mr. Piekarz:

Converse Consultants (Converse) is pleased to present this report containing documentation of air monitoring and project oversight completed during demolition activities for Project Neon. Services were performed in accordance with the Nevada Department of Transportation Service Agreement P-217-12-013 dated October 5, 2012.

Visual clearance inspections were conducted after abatement activities. All mandatory ACMs, including all associated debris, were removed per specifications. Visual inspection methods were models from ASTM Designation: E1368-90. Perimeter monitoring was conducted during the removal of the swimming pool at 1301 Richards Court. Abatement and demolition activities began in April 2014 and were completed in May 2014.

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

Respectfully submitted, CONVERSE CONSULTANTS Philip Childers, CEM Asbestos and Lead Manager

Asbestos Air Monitoring Report 1.0 Introduction and Summary In April 2014, Silver State Construction Technologies began the removal of Regulated Asbestos Containing Material (RACM) materials from the following buildings: 1217 Richards Court; 1225 Richards Court; 1301 Richards Court; 1305 Richards Court; 1213 Charmast Lane; and 1520 Ellis Avenue (there were no ACMs identified at 1205 Charmast Lane, 1501 W. Charleston Boulevard and 1505 W. Charleston Boulevard). Visual clearance inspections were conducted by Converse after abatement activities were completed in each building; the visual clearance letters are included in Appendix A. As allowed by EPA and Clark County Department of Air Quality (DAQ) regulations, selected Category II non-friable ACM materials were left in place during demolition. Lead containing paints on the building exterior was scraped and stabilized before demolition work began at 1213 Charmast Lane. Work was completed in May 2014 and was performed in accordance with the Nevada Department of Transportation Service Agreement P-217-12-013 dated October 5, 2012. This report summarizes the results of the asbestos oversight and air monitoring conducted by Converse during the building demolition activities. Included in the appendices are the visual clearances, laboratory results for air samples collected during air monitoring, daily logs, and waste manifest.

2.0 Purpose and Scope of Work The purpose of our work was to 1) conduct visual inspections after abatement activities, 2) monitor the perimeter of the regulated area for airborne fiber release during the demolition of the swimming pool and 3) supervise the stabilization of lead containing paint before demolition activities occurred. Our scope of work included project oversight, visual inspections, air sample collection, laboratory analyses, and report preparation.

3.0 Methodology

3.1 Air Sample Collection The perimeter air monitoring was conducted using high volume pumps. Calibration of the pumps was conducted using a calibrated secondary

Neon, Package B, Final Report For Demolition Oversight

Page 2

calibrator (i.e., Rotometer). The sampling media (cassettes) consisted of 25-millimeter (mm) diameter mixed cellulose ester filters (MCEF) with a 0.8-micron pore size. All pumps were calibrated with in-line cassettes on-site. Airflow rates between 2.5 and 10 liters per minute were used during the monitoring conducted during the swimming pool demolition monitoring. Samples were transferred to an analytical laboratory with appropriate chain-of-custody documentation.

3.2 Air Sample Analysis Samples were analyzed by EMLab P&K of Irvine, California by Phase Contrast Microscopy (PCM) using National Institute of Occupational Safety and Health (NIOSH) Method Number 7400. EMLab P&K is accredited under the American Industrial Hygiene Association (AIHA) Industrial Hygiene Laboratory Accreditation Program (IHLAP) for PCM airborne asbestos analysis. Laboratory reports are included in Appendix B.

4.0 Findings There are no national ambient air quality standards for asbestos. Therefore, Converse compared the results to the OSHA permissible exposure limits (PEL) of 0.1 fibers per cubic centimeter (f/cc). The samples collected were well below the PEL.

5.0 Closure and Limitations This report is for the use of the Nevada Department of Transportation as it applies to Project Neon structural demolition. Converse is not responsible for any claims or damages associated with interpretation of available information. This report should not be regarded as a guarantee that future exposure to airborne asbestos fibers will not occur.
