THA / Chemical Storage Facility/ 1010 Industrial Drive, Stockton CA / Drilling HASP 2 <br />plan(s). MGA is the single point of responsibility for permit compliance and safety. MGA <br />conducts routine and non-routine groundwater, sampling and remediation system performance <br />monitoring. MGA oversees all construction projects including subcontractor compliance of <br />site-specific safety plans. <br />MGA sub-contractors provide specialized services beyond that of the contractor such as: <br />drilling, excavation and waste disposal. All work shall be performed under the MGA's HSO <br />supervision. <br /> <br />3. TASK/OPERATION SAFETY AND HEALTH RISK ANALYSIS <br />This section defines the hazards and methods to protect personnel from unnecessary risks as <br />identified by previous site work, background information, current site conditions, and planned <br />site tasks. <br /> <br />3.1 Current Site Conditions <br />The site currently operates as a chemical storage facility. Surface conditions are little to no <br />gradient and are generally comprised of soil. The site is bounded by Industrial Drive to the <br />north. <br /> <br />3.2 Contaminants of Concern <br />Based upon historical use at the site, it is suspected that VOC's and dissolved metals, are the <br />site contaminants of concern (COC). <br /> <br />3.3 Task Hazard Analysis <br />The evaluation of hazards is based upon the knowledge of the site conditions and anticipated <br />risks posed by the specific operations. The following sections describe each task/operation in <br />terms of the specific associated hazards. Additionally, the preventive measures to be <br />implemented during initiation of those operations are also identified. <br />3.3.1 Mobilization and Demobilization <br />General hazards encountered during initial mobilization and demobilization for site activities <br />include the following: <br />Physical hazards of using heavy equipment in mobilization procedures. <br />Buried or overhead utilities. <br />Driving hazards such as driving on uneven and or unpaved surfaces, striking objects, <br />flat tires, and pedestrian traffic. <br />Crushing or pinching hazard while placing equipment and/or falling debris on <br />operators, workers, or observers. <br />Noise from heavy equipment operations. <br />3.3.1.1 HAZARD PREVENTION <br />Keep area clear of all observers; operators need to act with caution during the <br />mobilization process. <br />Obtain clearance from appropriate utility services prior to any digging. <br />Properly maintain vehicles. Vehicle maintenance can prevent avoidable vehicle <br />breakdowns in the field. In order to minimize accidents from uneven terrain, site <br />surveillance should be performed on foot to choose a clear driving path. <br />Verify that heavy equipment operations do not affect the existing overhead utilities. <br />R:IProjectsITHA1003-Stockton Phase II ESAIDrillingIHASP McGinley and Associates, Inc.
