USE OF THIS REPORT

This report is intended to provide an understanding of the potential hazards associated w ith the activities evaluated in this report. This report is based primarily upon data and information obtained during a single s ite visit by Aurora Industrial Hygiene, Inc. to the Hollywood Park Race Track facility, located in Inglewood, Ca lifornia on September 18, 2013 and is based solely upon the work practices observed and conditions of the fac ility on the date of the assessment.

Aurora has performed this work, made the findings, and proposed the recommendations described in this repmt in accordance with generally accepted industrial hygiene and environmental sc ience practices in effect in California at the time the work was performed. This warranty stands in lieu of all other warranties, expressed or implied. While this report can be used as a guide, it must be understood that it is neither a rejection nor an endorsement of the facility. It must also be understood that changing circumstances in the environment and in the work processes can a lter radically the conclusions and information contained in this report.

1.0 INTRODUCTION

This rep01t documents the findings, recommendations, and conclusions from the industrial hygiene sampling conducted by Matthew Froehlich, Field Industrial Hygienist, under the supervision of Karen Shockley, Certified Industrial Hygienist #6766, at the Hollywood Park Race Track, located in Inglewood, California.

Area air sampling was conducted at three locations around the track, and two locations in Bam 61.

Air sampling results indicated that total particulate, respirable patticulate, total petroleum hydrocarbon, and bromadiolone levels were well below the OSHA Permissible Exposure Levels.

2.0 PROJECT HISTORY AND PROCESS DESCRIPTION

Aurora Industrial Hygiene (Aurora) was retained by the California Horse Racing Board to do air monitoring at the Hollywood Park Race Track facility. The analytes and sample locations were specified by the California Horse Racing Board.

Aurora visited the Hollywood Park Race Track on September 18, 2013 and met with Jeff Salmon, Safety Steward. Air sampling was conducted during a morning training session with the horses and afternoon maintenance of the track. There were approximately 40 horses on the track during the morning session. The training session lasted approximately two hours and consisted of trainers galloping and breezing horses around the track. Sampling continued after the training session, during grooming of the synthetic race track, which involved tractors "harrowing" to redistribute track material. Additional air sampling was also conducted inside Barn 61 in feed room I and in-between stalls 40 and 41.

Appendix A contains a sate llite photograph of the race track with the area sample locations indicated. Appendix B contains photographs.

3.0 SAMPLE COLLECTION AND ANALYSIS

3.1 -Air Sample Collection

The air samples were co llected in accordance with the most recent (4th Ed.) National Institute of Occupational Safety and Health (NIOSH) methods, where such methods have been estab lished . Specifically, sampling was performed using Sensidyne personal sampling pumps, which were calibrated prior to sample col lection (pre-ca librated) and at the end of the sampling event with a DryCal DC-Lite Precision Flow Meter (SIN I 09309, calibrated November 15, 20 12) or a calibrated rotameter (#LB-003). The flow rate for each sample was established as an average of the two values.

Air samples were co llected using pre-weighed polyvinyl chloride filters for total and respirable particulates (dust). Additionally for the respirable particulate samples, a size­selective sampling device (cyclone) was attached to the sampling train preceding the filter so that non-respirable-sized particles were excluded from the sample. Coconut shell charcoal sorbent tubes were used to col lect total petroleum hydrocarbons samples. Bromadiolone samples were co llected on mixed ce llulose ester filters. Hydrocarbon samples were refrigerated after sample col lection and kept cold during shipment. No additional preservation of samples was necessary.

Air samples were co llected and analyzed by the fol lowing methods:

Particu lates not otherwise regulated (PNOR, total dust)

Respirable particulates (PNOR, respirable dust)

Total petro leum hydrocarbons

Bromadio lone

NIOSH Method 0600, Grav imetric

A unique sample identification (ID) number was assigned to each sample. This ID number was placed on the sample media immediately upon completion of each sample's

collection. The ID number, flow rate, calibration data, worker name or sample location, and time were also recorded on the sampling data sheet.

Proper transfer of samples from project site to laboratory requires documentation and custody procedures. Components of sample transfer documentation include sample labels, a chain-of-custody record, and a sample analysis request form. All documentation entries were made with waterproof ink.

All air samples were delivered by Federal Express under proper chain of custody to Bureau Yeritas North America, Inc. (BY), located at 22345 Roethel Drive, Novi, Michigan or ALS Environmental (ALS), located at 960 West LeVay Drive, Salt Lake City, Utah. BY and ALS are licensed and accredited to perform air sample analyses by the American Industrial Hygiene Association (AIHA).

3.3 -Atmospheric Monitoring

Weather data was recorded from weather station data collected at the nearby Hawthorne Airport. Weather station data from the Hollywood Park station was not available for the day the survey was conducted.

The following table summarizes the atmospheric measurements.

5.0 DISCUSSION AND RECOMMENDATIONS

The federal government and the State of Cali forn ia have defined Permiss ible Exposure Limits (PEL) for chemical exposures in the workplace. These limits refer to '·a irborne contam inants to which nearly all workers may be exposed daily during a 40-hour workweek for a working lifetime without adverse effect. Because of some variation in individual susceptibility , an occasional worker may suffer discomfort, aggravation of a pre-existing condition, or occupational di seases upon exposures even below the values specified. The exposure limits established by this section reflect current medical opin ion and industrial hygiene practice, doubts being resolved on the s ide of safety, and are intended to be used in accordance with good industrial hygiene practice by qualified persons7

"

The Cal-OSHA PEL's are as follows:

Particulates Not Otherwise Regulated (PNOR), or Total Particulates- I 0 mgfm3;

Respirable-Sized Particulates- 5 mgfm3; Total Petroleum Hydrocarbons - 300 ppm8

;

Total petroleum hydrocarbons and total particulates were detected in some of the area a ir samples, at leve ls well below the Permissible Exposure Limits. Respirable-sized particulates and bromadiolone were not detected in any of the air samples.
