Jack f. Oarratt, St. Loull September 25. 1969 Pydraul 135 at Oxaloaunda Jaraverk J. Haggart Bruaaala Z have baan aakad by Nr. dinar t. Whoalor to anewer tha call report datad Saptanbar 2, 1969, that you aant to him. Pydraul 135, * you know, contalna Aroolora. I hava attaohad a ausaaary of tha animal toxicity data on tha aubjeot product. Zt appaara that Oxaloaunda haa a cooling ayataa that la probably aaturatad with tha Pydraul fluid eompouenta. At about 25C thia moana that thalr circulating cooling ayataa can contain 200 ppb (parta par billion) of diaaolvad Aroclor 1242. Thia ooncantratlon la not aoutaly toxic to noat adult flah. Zt la poaalbla that this material la chronically toxic to flah and otbar aquatic apaclaa. Tha awan and duck mentioned in tha eall raport probably conaumed tha Pydraul in full atrangth ahila foraging in tha laka. Birda of thia typa foraga by diving to tha bottom of ahallow bodiaa of wator for food. If tha Pydraul ia not removed or raduead, thara will ba additional daatha of thia typa. Z would auggaat that tha acmpany lnvolvad begin to rovoraa tha Pydraul buildup by trapping and removing tha Pydraul. Znoldantally, thay night profit by thia ayataa if tha raoovorad Pydraul can ba rauaad. A collaotlan auav with tha naoaaaary puapa ahoald Ba lnatallad probably in tha baaaaant of tha faotary. If tha buildup in tha cooling laka naada to ba raaovod, it can ba dona by auction froa tha lowoat polnta ia tha laka. Thia will not nacaaaarily raliava tha duek and awan taxiolty problaa aInca tha bottoa allaaa and mud ara probably aatu ratad with Aroolor 1242. After tha wap la lnatallad and tha Pydraul la being routinely raaoved, tha problem in the laka will dAmlnlah alowly aa tha Pydraul dlaaolvaa and unoontaalnatad aollda cover over tha praaant bottoa allaaa. Z wlah thara waa a aaglc aolutlon to tha problaa wharo tha effaota can ba quickly reveraed. Ohleaa the ooapany ia willing to oapty tha laka and remove tha Pydraul along with about alx lnohea of tha bottoa allt, thara can bo trouble for aoaa tlaa. iju c.c. W. R. Richard Jack T.
