t <br /> II <br /> b. Site perimeter shall also be monitored on 30 minute intervals. <br /> Monitoring frequency would be increased by the site manager if <br /> conditions approach alarm level. F <br /> SITE PERSONNEL <br /> Breathing zone vapor concentrations at the borehole greater than the <br /> Permissible Exposure Limits (PELs) require site .personnel to use a respirator F <br /> i with organic vapor cartridges and goggles. <br /> Breathing zone vapor concentrations at the borehole that approach the maximum <br /> element capacity of the organic vapor cartridge1requires site manager to i <br /> monitor site perimeter (concentrating in the down wind direction) . <br /> Breathing zone vapor concentrations at the borehole that exceed the maximum <br /> element capacity of the organic vapor cartridgelrequires site activities to be # <br /> stopped until concentrations decrease. Site manager should continuously <br /> monitor site perimeter. <br /> SITE PERIMETER <br /> Breathing zone concentrations at site perimeter less than the PEL, site <br /> r manager shall monitor on 30 minute intervals unless notified by project <br /> Lpersonnel of elevated readings. <br /> t <br /> Breathing zone concentrations at the site perimeter greater than the PEL, site i <br /> manager shall continuously monitor conditions on site boundary concentrating <br /> in the down wind direction. i <br /> Breathing zone concentrations at site perimeter "greater than the PEL, site <br /> manager shall continuously monitor conditions. I,If the PEL continues to be ; <br /> L exceeded for 15 minutes, drilling activities shall be stopped. <br /> Breathing zone concentrations at site perimeterlgreater than the PEL, site <br /> manager shall immediately stop drilling and clear site personnel. Appropriate i <br /> regulatory agencies should be contacted (see below) . Site manager shall <br /> continue to monitor conditions until levels are 'reduced to background <br /> concentrations. <br /> f � ' <br /> Lr <br /> I <br /> i <br />
