The Center for Biological Diversity (CBD) American Bird Conservancy (ABC), and others have challenged the recent Environmental Protection Agency (EPA) denial of their petition asking the EPA to ban the use of lead as a component of hunting ammunition. The groups contend that, contrary to the EPA's assertion, the agency does have the authority to act under the Toxic Substances Control Act (TSCA). The petition also called for a ban on the use of lead in fishing gear, and that part is still under consideration by EPA. Since the EPA denial of the petition on August 26, CBD has filed a Freedom of Information Act request with EPA to obtain copies of all documents and materials related to the EPA decision.
