'v. may 281974 The: Bureau of Water Management*s Inst progress report to the Commission on tl:C PCB situation-W35 in December, 1S?71. Gome of you have requested an updating. That is the purpose of this report today, .. . Since the last briefing to you, EPA lias corse out with a recommendation that receiving waters should not contain PCK's in excess' of 0.01 ppb. Such o low level was deemed necessary in view of the fact that research has demonstrated .biomagnification of PCB's in fish can be as high as 200,000 times the concentration in water to which they arc exposed. There is an indication now that EPA. may even lower their recommended level by adopting the recommendation of 0.002 ppb made- in the upcoming edition of Water Quality Criteria (WAS, 1972), commonly referred to as the "Blue Book", Anyway, the EPA recommendation of 0.01 ppb for receiving waters has provided us with a guideline to use in reference to our monitoring programs. . i i v VI *- w */ -- -- -- -- * -- ' .. _ ^^ v >- V k V V O Vtvt V h V> on stream sediments, municipal raw water intakes, groundwater drinking supplies, sanitary landfill runoffs, municipal-wastewater treatment plants, industrial . discharges., o.ud fish from both inland and /Great.

It is interesting to note.that fish from the Saginaw River were found to have PCD concentrations as high as 163 ppm (Table.2). Five Michigan streams had mean concentrations in'water samples over 0,10 ppb, 1.0 times higher than the.: EPA. .guideline. These were the. Sagiriawj''Tittebiwassee,' Cl in'toft', Raisin' and Roupe.

' ' centrations with means of 0;04l and 0.065 ppb,'respectively. ;. .- . In May , 1973 (just last month) we sampled the water in the Lower -Perinieuia tributaries agbin and found just 8 (36 percent) exceeding the 0.01 ppb guideline (Table 3). This is r.n apparent improvement over previous years which we hope Is the beginning of a downward trend. Improvements were especially noted in the Saginaw, Tittabawassee, and Raisin Rivers. ' . Sampling of municipal wastewater treatment plant (WWTP) effluents' throughout Michigan in 1971 and 1972 indicated that many WWTP's represent major point sources of FCB loss to surface waters (Table 4). The average PCB concentration of 60 effluents sampled was 2.55 ppb. V.'hilc only seven of the VRTTP effluents exceeded' 1 ppb, the Bay City WWTr located on the Saginaw River had on average effluent concent ration of 120 ppb (Riga of 340 ppb), skewing the over-all average for ail plants 'sharply upward. The. average concent ration excluding the Say DSW 037499 # STLCOPCB4021323 ^" , of PCB contamination. One would tend to believe that if .industrial . li.i.'i been decreased, it t^ould be reflected first in reduced concentrations charges from wastewater treatment plants, Sampling of 58 YIWLT effluents i, however, continues to show high PCB levels with an average concentration - ppb (Table 5), including the Bay City plant, Although still high, . vlear- that the.'PCB discharge from the Bay City WWTP has been greatly reduced. Sampling of sewage sludge from 57 of the 58 WWTP's tested in 1973 showed piiy to have the highest concentration of PCB's in the sludge being removed . v.; treatment process. The PCB concentration in the sludge'from the Bay , pL'mt was 352 ppm (dry weight basis) compared to a state-wide average of . ppm (Table 6). - '. . '. ** '* * . In an attempt to identify major contribv rs of PCB's within municipal systems, sampling at key points in the : .terceptor systems has been ' ..acted within the municipalities of Bay Cr.y, Ht. Clemens, Saginaw, Adrian, .eit and Kalamazoo. This program has bet-i very successful in that it has vLficd numerous PCB sources. In most cases, our agency has contacted the . stries identified and 'nave asked for corrective action. The City of Detroit, .ever, has taken its own initiative and is getting good cooperation. Two of *'i major sources identified in the Detroit, system have completed a changeover non-PCB products and the other two are underway. A broad scale sampling of industrial discharges throughout Michigan has shown -..alts indicative, of the widespread usage of PCB's. .Nearly half , of the .industrial ' ' ' .`barges'- sampled have contained moire than 0.1 ppb with' many in excess of 1 ppb'. ' . . highest concentration. detected ip an industrial discharge in Michigan has .. ... r .v. 7,200 ppb and thifc -vas just found recently. Automotive, plants, chemical hn^' 'p;Spdr 'ptd'd'j'ct 'n'ah'Oifa''c'^ut,ers'''ai!,e among the "typcs ' cif "industries' with'' ...st concentrations..

We view . ... . Continuing s.carch .Dr.-sources as..'a necessity so that we can speed, up the : '*: rvgeover process. There are some indications that even after an industry ' - the use of. PCB's a.residual is going to continue in their effluent for . ._ ./iderable length of time-until the. .sewers. con be completely.,, flushed out.,- . are encouraged that some rivers are starting to show reductions in PCB itrations. An example of one location in Michigan where monitoring and 'guent control measures have resulted in a marked reduction in PCB contamination ' 'C Saginaw River basin. Monitoring of major Grea.t Lakes tributaries during 1972 identified the Saginaw River as having the highest concentrations of ; <>f any tributary within Michigan boundaries. Intensive sampling throughout '(vcr basin in search of point sources successfully isolated ten major points B dischargeto the river system. Each of the industrial sources'were asked '"unify the cause of their losses and to take corrective action. The following :l Mating of the point sources and corrective actions taken to this date: ' U'-vrolct Bay City Parts Plant - PCB's had been used as hydraulic fluids in the die-cast machines. Losses were occurring both, in the cooling DSW 037500 STLCOPCB4021324 . Oar ln9t report from General Motors showed conversion to a phosphatc- ' . ester based compound about 50 percent completed. ' '- '. Bay City IJWTP - Interceptor sampling identified the Chevrolet Parts Plant ns. the major contributor to this sytem. Since the initial steps of the General Motors plant conversion away from PCB fluids, the PCB levels in the .WWTP effluent have dropped to about 1 percent of the previous highs. General Motors Grey Iron and Nodular Iron Foundries, Saginaw - The problem here was also related to losses of hydraulic fluids. Conversion to phosphate ester fluids is reported to be complete. . Saginaw WWTP - Concentrations of PCB's in the effluent were not nearly as ` high as in the Ray City Plant. The Grey Iron and Nodular Iron Foundries ' were identified as the major contributors to the system. Concentrations . in the WWTP effluent have declined to about 50 percent of their previous levels. . Bulck Motors, Flint - This plant was using PCB's as hydraulic fluids in 13 die cast machines. Conversion to a phosphate ester-glycol product . was completed November 1, 1972. *. Chevrolet Van Slyke Engine Plant, Flint - A coolant containing PCB's has been replaced with a substitute product. - / ..'..Flint .VUTfP.r Concejitrations'have steadily .declined, since- our 1st .sampling . period in the fall of 1971 and now are considered very low.

Ve- n. report*. V V - `s- jyou '..'ill note , -u ~. our monitoring site hear the''river mouth in October, 1972, Concentrations' have' remained fairly low ever since that datewith the exception of the sample from last month which' indicated an increase back up to 0.2 ppb. . Overall the Situation appears to have improved considerably and we hope that a corresponding decline .in PCB concentrations .in fish from the river and the Saginaw Bay will soon .. be observed. ' ' " ' M 'v" ' ' ' You may recall that in May, 1972 vie reported to you about a PCB situation in the Kalamazoo River. During our intensive water quality and biological survey of the Kalamazoo watershed we discovered sharp increases in PCB's in fish below the ..municipalities of Battle Creek and Kalamazoo. Follow up surveys v;ere unsuccessful at identifying any major sources iq Battle Creek but in the Kalamazoo vicinity surveys have pointed the finger at both past and present wast.epaper recycling operations by the paper industry. Certain sediment deposits in an impoundment on Portage Creek, a tributary to the Kalamazoo River, were found to contain PCB's at concentrations excco-dlng 350 ppm (dry weight basis). Leaching - r * . DSW 037501 STLCOPCB4021325 from'these PCB enriched sediments appears to be significant. During a drawdown of the impoundment .last summer, scouring of the bottom sediments occurred and n sharp rise in PCB levels in river water was observed as the. .sediments moved downstream. As a result of sampling within the WWTP interceptor system, it ic apparent to us that the remaining dc-inklng operations are still contributing to tlie PCB contamination problem. We arc not sure what the solution to this problem might be because it would obviously involve a policy decision at the National level about the merits of-recycling paper.- - . . . r t i In 1972 Michigan developed a cooperative State-Federal study of contaminant levels in Great Lakes fish species including lake trout, salmon, whitefish, chubs, nenominee, yellow perch, alewife, carp, and suckers. Fish from Lakes Michigan, Huron, Erie, and Superior are systematically being sampled on an annual basis to obtain information on areas where contaminants approach or exceed FDA guidelines for consumer protection. The project, developed by the State agencies in cooperation with the U.S. Food and Drug Administration and the Bureau of Sport Fisheries and Vlildlife Great Lakes Laboratory, will establish patterns of residues of mercury, FCB's, DDT and dieldrin in Groat Lakes fish. Table 8 shows the concentrations of PCB's detected in fish from X,ake Michigan during the first year of this study. PCB's in Salmonids (lake trout, stcelhead, coho salmon, and chinook salmon) and chubs were shown to exceed the FDA guideline of 5.0 ppra while concentrations in other species did not exceed this guideline. Sampling will be continued on an annual basis. ! j I I ' . One area in which we have very little information so far Is the potential for -lo&s of-PCB's from-electrical -transformers':(ohe''.of'the'two- refraining uses) through leakage, servicing, and replacement of worn-out or damaged units.
