The risks arising from the work being performed: impact to workers, <br /> community and the environment;Exposure monitoring plan;personal protective equipment <br /> and engineering controls; Site controls including work zones and security measures/ <br /> decontamination procedures. <br /> • Overall work practices;with sanitation facilities/plans.Emergency response plan addressing <br /> hazardous material/waste releases; personnel training requirements; personnel medical <br /> surveillance program/record keeping.Requirements that all field personnel will be trained in <br /> hazardous materials communication and will have completed a 40-hour Health and Safety <br /> Course as specified in OSHA Hazardous Waste Operations and Emergency Response <br /> Standard [29 CFR 1910.120(e)], and 8-hour annual refresher courses as necessary. <br /> • Prior to digging activities,each proposed digging location will be clearly marked and an utility <br /> clearance obtained through Underground Service Alert. <br /> 3.2. INSTALLATION OF REMEDIATION WELLS <br /> An SVE system is proposed to reduce petroleum hydrocarbon mass from the petroleum hydrocarbon- <br /> impacted area at the site. In order to maximize the efficiency of the clean-up efforts, a 24-hour <br /> operation of the system is planned. A typical destruction rate of greater than 95% of hydrocarbon <br /> vapors is expected throughout the entire cleanup duration. <br /> Three additional SVE wells will be installed at the site to supplement remediation efforts of the <br /> petroleum hydrocarbon impacted area at the site. Proposed SVE well locations are illustrated in <br /> Figure 3. <br /> Based on an estimated SVE radius of influence of 25 feet(Corrective Action Plan,dated 16 October <br /> 1994), AGE proposes installation of three SVE wells in the following locations: <br /> • approximately 25 feet north of vapor well VW-1; <br /> • approximately 20 feet southwest of vapor well VW-1; and <br /> • approximately 30 feet east of vapor well VW-1. <br /> One additional ground water extraction wells will be installed north of well MW-5 to enhance the <br /> recovery and treatment of ground water. The procedures to be utilized for the well installation were <br /> previously approved in Monitoring Well Installation and Interim Ground Water Remediation Work <br /> Plan dated 26 October 2000. The proposed ground water well location is illustrated in Figure 3. <br /> Advanced GeoEnvironmcntal,Inc. <br />
