>Dear Ms. Lisa
>How are you? I would like to introduce myself as Ashwin Arumugham

>Gainesville. We are funded by the USDOE and are working under Rutgers

>in to productivity and waste.
>This is regarding a particular company that we had visited last week.
>They manufacture utility poles and marine pilings. Basically it is a

>chemical known as CCA ie Chromated Copper Arsenate which is a
>highly hazardeous chemical. After treating it, they cut it to the
>required dimension and sometimes they are left off with 5 foot logs.

>Another point that we are considering to look into is the chemical

>feet long. It has a single door like the door for a bank vault.
>It has about 130-135 bolts that have to be manually removed and put
