## Abstract

The purpose of this action is to revise the current nontoxic shot approval procedures by establishing a tiered approval process. Shot or shot coating approval is considered at each tier. An environmentally benign shot or a minor modification of previously approved shot may receive nontoxic approval after the first tier contingent on existence of appropriate toxicological data and an ecological risk assessment. If not, further testing would be required.
