Also, to report all data on Aroclor residues in the Snow Creek - Choccolocco Creek Watershed. To summarize progress to date on Aroclor clean-up efforts at Anniston. PERSONNEL: E. G. Wright, (J. T. Bell) REPORTED BY: E, G. Wright SUMMARY: Aroclor losses from the Annistor Plant for the period April 15 through June 30, 1970, averaged 16 lbs./day. This is a considerable Improvement over the losses of^250 lbs./day for a comparable period during 1969. This reduction has been primarily achieved by an education program and by changing operating habits. However, projects are being Installed and evaluated which will further reduce these losses toward the Business Group goal of 10 ppb. FUTURE WORK: 1. Continue sampling and analyzing for Aroclor looses on a routine basis. 2. Continue to sample and analyze grab samples from Snow and Choccolocco Creeks for Aroclor content. 3. Sample and analyze ambient air for Aroclor content. 4. Sample and analyze tank vents in the Aroclor department to pinpoint atmospheric loss points. 5. Collect additional aquatic samples from Choccolocco Creek Watershed. 6. Issue periodical reports on Anniston Plant losses and progress toward 10 ppb goal. MCNS 056663 E. G.

HC1 Sever Since the installation of a catch tank in the 1IC1 gas line and a coalescer in the acid stream, the Aroclor content in the waste acid stream has been greatly reduced (i.e., Approximately 200 pounds of organic material is being removed by these two projects.)* During the sampling period, this sewer averaged 13.0 ppb of Aroclor. (See Data Sheet I.) Based on this data, the decision was made not to route this stream to the sump presently being installed. This resulted in a substantial savings on installing the sump. However, at times, the spent carbon from the HC1 carbon towers is dumped into this sewer. Alternate methods are being evaluated to eliminate this situation. B. Chlorlnotor and Still Room Sewers At times these sewers had a two phase flow. The quantity of the Aroclor phase could not be determined. However, these two sewers Are being routed through the Aroclor sump. When the sump is completed and put Into operation, the Aroclor phase can then be quantified. The sump will, also, provide a means for recovering this second phese, which under present conditions eventually makes its way out of the plant. When the sump is installed in these sewers, a dally sample will be taken and analysed to determine the efficiency of the sump. Other projects are also scheduled which should result in a reduction of Aroclor In this process stream. C, Warehouse Sewer The major losses from this sewer are due to spills while drumming or flaking. These spills are then swept to the sewer during floor clean up. Presently, clean-up is accomplished by use of Du-Bois steam cleaning which considerably raised the solubility of Aroclor in water. Alternate methods of clean-up end diaposal are presently being evaluated. D. Totsl Plant Effluent During the period April IS to June 30, 1970, the total plant losses averaged 1C lbs./day. This is excluding the period April 21 to June 20, 1970, when the acid neutralization pit was being cleaned out. During this period, the losses ran very high (See Data Sheet V.) due to the fact that the Aroclor which was trapped in the pit was being stirred and entrained into the plant effluent. The discrepancy between the 1.7 lbs./day losses from the severs nr.d the 16 lbs./day losses reported from the plant effluent may possibly be due to two things: 1) Samples from the sewers did not include any of the Aroclor phase and 2) Due to the mixing and the velocity at the plant effluent sampler, eomo of the Aroclor was being entrained and therefore MODS 0 5 6 6 6 4 Ann is r.on Plant Progress Report 002-1026 (2) Page 3 giving higher results. A closer correlation is hoped for when an accurate measure of the Arcelor phase can be accomplished. Close observation of the sump should provide this information. E. Miscellaneous Samples (Data Sheet VII) These samples were collected from Snow and Choccolocco Creeks at various times. They show that Aroclors are present in the Choccolocco Creek even above where the Monsanto effluent enters the creek. They also indicate significant amounts of Aroclor in the mud and water of Choccolocco and Snow Creeks a considerable distance (15-20 miles) downstream from the Anniston Plant. In fact, Aroclor concentrations can probably be found in the Coosa River system. Data Sheet VII contains a complete list of all the data to date on Snow and Choccolocco Creeks. Attached Is a mop of the watershed showing the sample location with respect to the plant.
