i t Mr. Ernst Maedorv Plant Manager . " Gulf Coast Aluminum - Lake Charles, Louisiana - t\- Dear Mr. Maedert " ' This latter will serve-tooconfinn our various, discussions concerning replacing Therminol FR-1 with Therminol -55 in'your heat transfer' : , system. In view of recent information concerning the persistence of Therminol FR-1 in the environment, we feel it would be in your best interest, as well as ours, 'to convert to a-heat transfer fluid which is relatively non-damaging to the environment. - . - Therminol 55 will: meet your operating perameters with one'.exception. That is, it is not classified as a fire resistant-heat transfer fluid While it is more'fire resistant than-many,, commercially available heat transfer fluids; it does-not. exhibit, the-,degree-of : fire resistance . found in Therminol FR-1.-.. Additionally,- it .tends .to-be unstable when exposed to oxygen at high temperatures.7 Therefore* it~is-necessary to blanket expansion tanks with .an. inert gas.. . , ,, . . In order to facilitate this change, Monsanto will assume the bulkof. : the financial burden. We have agreed-tol 1) take back all-un-used ' . fluid (unopened drums) at full credit. 2V-sell' you 6 ,500 gallons of replacement Therminol 55 at-450 per gallon, F.O.B.'=Alvin, Texas in tank trucks 3) pay the freight and expose of at.our exoense the, . Therminol FR-1 drain from your system 4) sell you 4-,500 gallong.*: - Therminol 55 to be used for system flushing at 300 per, gallon, F..b; Alvin, Texas in tank trucks , 5) pay 50% of the freight of this used . flushing fluid from your plant to our disposal point,-in St. Louis 6) dispose of the used flushing-fluid at our expense.'.. -M; v*7 . Vie would expect to utilize tank car or tank truck shipments in - . returning the used Therminol FR-1 and the Therminol 55, which has been used for flushing the system, to St. Louis for. ultimate.disposal. . .
