## Abstract

We (us or Fish and Wildlife Service) approve three shot types, Tungsten-Bronze [formulated of tungsten, bronze (copper and tin), and less than 1 percent iron], Tungsten-Iron (formulated of tungsten and iron), and Tungsten-Tin-Bismuth (formulated of tungsten, tin, and bismuth), as nontoxic for hunting waterfowl and coots. We assessed possible effects of all three shot types, and have determined that none of the types presents a significant toxicity threat to wildlife or their habitats. Therefore, further testing is not necessary for any of the types. An Environmental Assessment for each of the shot types is available from us. In our proposed rule we called tungsten-bronze shot tungsten- bronze-iron (TBI) shot. However, we have concluded that it is more appropriate to call it tungsten-bronze shot because it contains less than 1 percent iron.
