It seems the Center for Biological Diversity didn’t get what they wanted. The EPA denied their petition based on legal issues that were brought up by the National Shooting Sports Foundation (NSSF):
Steve Owens, EPA assistant administrator for the Office of Chemical Safety and Pollution Prevention, said, “EPA today denied a petition submitted by several outside groups for the agency to implement a ban on the production and distribution of lead hunting ammunition. EPA reached this decision because the agency does not have the legal authority to regulate this type of product under the Toxic Substances Control Act (TSCA) – nor is the agency seeking such authority.”
Good work everybody who wrote the EPA.
