C. 202SO October 29, 1970 PR Notice 70-25 N0V 30 1970 NOTICE TO MANUFACTURERS, FORMULATORS, DISTRIBUTORS, AND REGISTRANTS OF ECONOMIC POISONS Attention: Person responsible for Federal registration of economic poisons Elimination of Polychlorinated Biphenyls and Polychlorinated Terphenyla from Economic Poisons l There arc accumulating data on the chronic toxicity of the polychlorinated biphenyls and polychlorinated terphenyls to fish and birds and the contam ination of the environment by these chemicals. Certain products containing these chemicals have been registered bv this Division for use primarily as insecticides. These chemicals have been shown to act as extenders in certain formulations to prolong the per sistence of the pesticide chemicals. Although the use of these chemicals in economic poisons is not considered an acute, hazard to man or hie environment, they do contribute to environ mental pollution. Any benefits derived from their use are outweighed by the resulting environmental contamination and the possible long range adverse effects on fish and wildlife. Therefore, the presence of these chemicals in economic poisons must bo phased out. Accordingly, formulators and manufacturers of economic poisons contain ing polychlorinated biphenyls and polychlorinated terphenyls should change their formulations to eliminate such chemicals either as active or inactive ingredients. It is believed that a period of six months is a reasonable period of time within which to affect sucli formula chonges. Five copies of a complete statement of composition and five copies of amended labeling should be submitted with the appropriate application form (PR Form 9-198). Applications should bear a prominent reference to PR Notice 70-25. Assistant Director HONS 079232 TOWOLDMON00475QO
