DRAFT 11/23/71 JFS Dear Customer 1 Our records show that our company constructed a 3II0 on your farm In the year 196__ . We were pleased to have had the opportunity to serve you because we value your patronage and we hope that your Monteagle silo has been an asset to you. We are writing you because questions have arisen concerning an Ingredient called poly0lorinated biphenyl (PCB) contained In the chemical coating which was used to seal the plaster Joints In the Interior of your silo. Recently some state agencies have detected PCB In milk and have, they feel, traced the PCB back through rtSd silage<^e=& dairy cattle to the silo coatings. In some Instances, the marketing of milk having a PCB content In excess of two-tenths of a part per million has beenfaendeiawed. ' ' We therefore reoommend that you have a sample of your silo coating and a sample of any silage you may be storing In your silo analyzed ^ by a qualified laboratory<^for~?CB content-*^ If the results Indicate that your silo coating contains PCB and that PCB Is passing Into your silage, you should give oareful consideration to whether you should oontlnue to feed your silage to dairy cattle, and whether It Isappropriate to resurface the interior of your silo. Very truly yours, MONTEAOLE SIDO COMPANY, INC. Charles Boswell President o`vb PCB-ARCH0744350
