The EPA received over 20,000 letters about the move, it says, but the vast majority did not support the continued registration of the devices.
The devices are used to protect livestock and protected species from predators like coyotes, foxes and feral dogs. But critics argue that they can harm people and non-predatory animals that may stumble upon them.
The EPA included some restrictions in its review, such as requiring that all occupants within a half-mile radius be notified of the device’s placement and that they be kept at least 50 feet from public roads or pathways.
But critics say those restrictions aren’t enough.
“While it is encouraging that the EPA is taking at least some minimal action to protect the public from deadly M-44s, updating a few use restrictions — nearly impossible to enforce and commonly ignored — fails to meaningfully address the problem,” Kelly Nokes, a wildlife attorney, said in the Center for Biological Diversity’s statement. “EPA is blatantly ignoring its fundamental duty to protect the public, our pets, and native wildlife from the cruel, lethal impacts of cyanide bombs lurking on our public lands.”
