Site Safety and Health Plan Stockton Field Maintenance Shop #24 8020 Airport Way, Stockton, CA 8.0 EXPOSURE MONITORING AND AIR MONITORING PROGRAM Monitoring for the presence of hazardous conditions will be performed by the SSHO during drilling operations to prevent personnel exposure to chemical and physical hazards. Information gathered from air monitoring is used to determine appropriate on site protective measures and to design appropriate contingency plans and/or control measures to limit off site migration of contaminants. Monitoring activities and equipment are described in the following sections. All monitoring results will be recorded in the permanent log of all activities. These logs will be kept in the project files and submitted upon request. Information in the logs includes: Date and time of monitoring; Air monitoring location; Instrument, model number, serial number; Calibration/background levels; Results of monitoring; Personnel signature; and Interpretation of data by SSHO. 8.1 FIELD CALIBRATION All field calibration of monitoring equipment will follow manufacturer's procedures as listed in the operations manuals that are kept with each specific piece of equipment. The Field Equipment Calibration Data Sheet will be used to document the calibration results. 8.2 FREQUENCY OF AIR SAMPLING AND ACTION LEVELS Based on an evaluation of the contaminants at the site, Star will furnish and maintain real-time air monitoring equipment including an organic vapor monitor (photoionization detector (PID) with 10.2eV lamp, or equivalent). The frequency of sampling around drilling and sampling areas, and in the breathing zone will be: Every 2 hours (at a.m. startup, after a.m. break, after lunch, after p.m. break, all prior to resuming activities). Immediately after "unusual" events or incidents that raise exposure concerns. Air monitoring exposure limits are indicated in Table 8.1. If the PID equipped with a 10.2 eV lamp detects VOC concentrations at or above 1.0 part per million (ppm) and less than 10 ppm for a sustained period of 15 minutes or longer, a colorimetric detector tube will be used to determine if any of the contaminant is present (e.g., benzene). If the colorimetric detector tube indicates that VOC is not present, work will continue in Modified Level D PPE with PID monitoring conducted continuously. Level C PPE is not expected at this site. If airborne VOC concentrations rise to >10 ppm but <25 ppm, air monitoring utilizing colorimetric detector tubes will continue every 30 minutes for the duration of the work. If at any time the PID monitoring or the detector tube sampling indicates airborne VOC levels exceeding 25 ppm, the project work must cease and the work area evacuated. The Star PM and SHM must be notified in order to evaluate the situation and determine the next course of action. 27 Star Resources Corp
