Y %ftlo 4t <br /> Ground Zero Analysis, Inc. <br /> SITE SAFETY PLAN <br /> FACILITY BACKGROUND <br /> The site is operating as manufacturing facility that produces truck trailers. The facility formerly <br /> utilized a 1,100-gallon underground storage tank (UST) for the storage of regular and unleaded <br /> gasoline. The UST was removed in February 1999. Very low levels of ethylbenzene and xylenes <br /> were detected in soil samples collected from the UST excavation. <br /> WORK PLAN <br /> Task One: Advance three (3) soil borings using a truck mounted Geoprobe 5400 direct push <br /> drilling rig to depths of approximately 25 feet below ground surface in the area of the former UST <br /> to determine current concentrations of residual soil contamination resulting from past site operations <br /> and to determine if groundwater has been impacted by an unauthorized release. <br /> Task Two: Collect soil samples from each boring at minimum 5-foot intervals for logging and <br /> submittal to a state-certified laboratory for analysis. Collect a groundwater sample from one boring <br /> for submittal to a state-certified laboratory for analysis. <br /> JOB HAZARD ANALYSIS AND SUMMARY <br /> Chemical Hazards <br /> TASK{S} CHEMICAL PELISTEL/IDLN KN01NN SIGNSISYMPTOMS <br /> {SOIL,-MATER A1R, CONCENTRATION <br /> :.'ETC } <br /> 1,2 Benzene PEL 0.1 ppm (NIOSH)1 2.1 ppb (water) Irritation of eyes, nose, <br /> 1 ppm (OSHA) respiratory sys; giddiness, <br /> 14 ppb (sail) <br /> STEL 1 ppm (NIOSH)/ headaches, nausea, <br /> 5 ppm {OSHA) staggered gait, fatigue, <br /> IDLH 3,000 ppm anorexia, lassitude, <br /> dermatitis, human <br /> carcinogen. <br /> 1,2 Toluene PEL 100 ppm 2.1 ppb (water) Fatigue, weakness; <br /> STEL 150 ppm confusion, euphoria, <br /> IDLH 2,000 ppm dizziness, headache; dilated <br /> pupils, tearing, nervousness, <br /> muscular fatigue, insomnia, <br /> paresthesia, dermatitis. <br /> PAGE 2 <br />
