I and <br /> Margaret asked for one but they addressed other things and never answered <br /> the WDR question. <br /> - Do you have a contingency plan for the Ozone system? We can develop one <br /> and include in our RAP/system design. The simplest contingency would be to <br /> switch from ozone to air sparge, When we design the trench layouts we can <br /> add a couple extra vapor extraction lines going to the north in case we have to <br /> switch to air sparge, at which time we would want to capture vapors due to high <br /> air flow and possible stripping effect. You and I know if a problem arises, you <br /> turn it off, right? But what do you plan to do if Cr-VI or Bromate shows up? <br /> Initially we would shut off the ozone and confirm attenuation of the Cr-VI and <br /> Bromate. If attenuation was not shown then GWE would have to be <br /> 7/16/2008 <br />
