Baldwin Jcrpomtion 100 Park Avenue "ow dork 17, :;ow York Do ar Jim: In the natter of the disposition of sludge, as discussed in your ''later-* view Report" of September 12 (Yr, nasalka, Perth Amboy, ho?/ .Jersey), my opinion continues to be that fcao inactivation, of sludge from storage tanks used for leaded caaoline (inactivation .from the aspect of a potential lead oasard) Is not feasible* If it were, I should advise the application of such st method to the sludge within a tank before its removal and before it is .ined with water* The situation which gave rise to this discussion, however, is a real one, and it seems certain that this situation will arise more frequently in the Viture tnan it has in the past, l.e* the disappearance of suitable apace for the burial of sludge* The possibility of the use of a concrete tank as an Initial receptacle presents the possibility of a relatively long-term settling and cneraical treatment process, and In my opinion, this has real possibilities* Our people at the manufacturing plants (Houston ia particular) wive a waste handling plant which works, and. the adaptation of the methods used in it, to the problem at refineries, possibly on a slower, smaller and .-.tore economical basis, seems to me to be worth investigation* he might well collaborate with some conveniently located customer in an attempt to solve tnis problem satisfactorily* Our efforts to learn something about the time (and other) factors in the decomposition of the organic load compounds in -Varied sludge have been entirely unsuccessful, but they would not continue ao necessarily under the presumably controlled conditions established by storing the sludge in a concrete (or other typo) vessel* Vie might well find coat v;e can establish the rate of the inactivation of such sludge, and we may be able to aceolorate it by appropriate technical' moans* 1 look with disfavor on the dumping of sludge In the sea, not only because of the limited applicability of the procedure, but also because the principle is not good* In the long run we must ccno around to waste dis posal by sound tocnnical methods* Sincerely yours.
