Weather conditions have the potential to disrupt the project in that <br /> if it is raining, excavation and sampling should be postponed. It is unlikely <br /> that temperature conditions would preclude completion of the project. <br /> Temperature ranges expected to be encountered are 65°F to 95°F. If workers are <br /> F3 wearing Level G equipment and the temperature is more than 800F, workers will be <br /> }.= <br /> required to take 10 minute breaks every hour, rest in the shade and drink fluids. <br /> { Underground utilities should not be encountered, the 4-inch water <br /> t " main and electric conduit exposed in the excavation are the only subsurface <br /> utilities expected in the site area. <br /> ` E a REMEDIATION OPERATION <br /> ( , <br /> The potential for adverse health or safety risks Co the on-site <br /> workers or the immediate surrounding area are low.

Special arrangements for possible neighborhood <br /> evacuation should not be required. <br /> No unauthorized personnel may be permitted in the work zones during <br /> i <br /> the remediation operations. If local residents, reporters, etc. enter the work <br /> site, they should be informed that health and safety procedures have been <br /> �. established to protect both the workers and the public.
