J. R. Savage - Oeneral Office Kay 6. 1971 APRIL 1971 PCB REPORT H. S. Bergen P. B. Hodges W. IB. Papageorge Oeneral Offices V. 0. ItRUMMRICH PLANT I. PCB Level In Sewer Arcelor losses for the month of March and through April 18 are attached. Losses from Dept. 246 appear higher than previously reported due to rerouting of several department flows Including some that contain thermlnol units. The Pollution Oroup will try to find a new sample location which will Isolate the ABoclor Department losses. II. Program To Eliminate Sewered PCB'a Prom Using Departments A. Thermlnol Unit Change-Outs Dept. Status 255 222 - ONA 222 - PNA 244 243 (4 units) 270 IU 275 243 259 Complete Complete Drslned In April Complete 3 units oomplete. 4th unit will be changed out by 5/7. Completed In April. Completed in April Completed in April Department down .and unit drained. Will complete project work for operation with T-66 by end of Majr. Soheduled to be ehsngri out by 5/15Scheduled for mechanical completion n by May 15. B. All unlta using Pydraul A-200 In Dept. 251 changed out to Pydraul A-200B. C, Continuing to drum liquid caught at catch tank at Dept. 218. Drumming of liquid oaught at catch tanka at Dept. 217 atarted about mid-April. Program begun to determine PCB eewer losses resulting from Aroclor carried out as vapor In the HC1 off-gas from the Aroclor Department. Drowning Jet at Dept. 218 and CS acid sewubbera at Dept. 217 sre potential pointa of entry to the sewer. MONS 099014 Page a 8. ANNISTON PLANT PCB Levole In Sewer Current level Arodor loseee during April 1971 averaged 0.65#/d*y (71 PP>). Project| Evaluations 1. #1 HC1 pit will not be used until PR&D aollda reaoval work 1 completed. #2 HC1 pit la performing well enough to permit this delay. 2, Samples from 36 storm sewers reoently repaired to avoid Infiltration show definite decrease In PCS. Further analytical work required to determine magnitude. 3. Engineering work resumed on collection and disposal of 4pent carbon from HC1 Department. Premise target is Spills There were no known spills of Aroclor during the month. J. It. Savage md MONS 099015 - / e r-/ < > - p c b 0F0 Hay i n'yti/Z P(B - peer a y
