I also observed remediation workers using public <br /> restrooms. The only measure I observed being implemented to separate the public <br /> from the noise and other hazards associated with drilling operations was barrier tape. <br /> The public and remedial workers were literally standing or passing by next to one <br /> another during this fieldwork event. The workers wore hard hats steel-toed boots and <br /> ear protection. The public, essentially situated within the same distance of the drill rig, <br /> had no protective equipment or physical barrier to prevent exposure to the inherently <br /> dangerous drilling operations and possible contamination. I made a number of <br /> suggestions to Levine Fricke (LFR) including providing temporary sanitation facilities for <br /> the workers and appropriate barriers to prevent the public from entering into the <br /> construction zone. <br /> Although the fieldwork such as drilling, excavation and sampling occurs on private <br /> property, the activities easily impact public areas. As with any construction zone, the <br /> public needs to be protected from dangerous situation from operating heavy equipment; <br /> unsecured materials, dusts, and vapors; noise; and possibly projectiles or uncontrolled <br /> incidents. Consideration needs to be made to temporarily closing the affected public <br /> areas possibly through the City's encroachment permit process. In some cases <br /> business concerns or other public access issues may require that the public have <br /> access to areas close to fieldwork activities. If so, physical barriers such as temporary <br /> fencing, plywood paneling, noise barriers etc. should be used to protect the public. I <br /> also recommend that in the future, the City and DTSC require that all remediation <br /> contractors provide job site sanitation including temporary sanitation facilities for the <br /> workers and worker hygiene facilities when conducting field work in Lodi. <br /> Prior to beginning each fieldwork mobilization, I recommend that a representative from <br /> the City of Lodi, DTSC and the respective remedial contractor(s) meet to discuss the <br /> scope of the fieldwork to be performed and evaluate the potential for public safety <br /> hazards. This evaluation should in all cases include a joint site walk tour to identify <br /> appropriate work practices and controls for protecting public safety during fieldwork. To <br /> ensure the identified public safety controls are implemented, the City may consider <br /> outlining the requirements as part of the encroachment permitting process. In addition, <br /> the site safety officer for the project (typically the contractor) should identify public safety <br /> controls in an addendum to the CAL OSHA required worker health and safety plan to <br /> ensure that workers can implement them. <br /> The next GLA field mobilization will be when LFR conducts well development and <br /> vacuum testing for the wells installed in July. Excavation for subterranean piping and <br /> traffic boxes for the SVE pilot system will soon follow. The City and DTSC and <br />
