Tom - as we have already discussed, the inspection that i conducted today
showed no permit compliance problems and no reason to delay in processing
the renewal. The draft looks OK. The staff report for this permit
renewal is attached to this e-mail. A hard and signed copy will follow
for the files. Call me if questions. Max

Tom, it would appear that a 1.43% chronic limit is appropriate based on our
