To prohibit the use of M–44 devices, commonly known as  cyanide bombs , on public land, and for other purposes.
1.
Short title
This Act may be cited as   Canyon’s Law  .
2.
Findings
Congress finds the following:
(1)
Sodium cyanide is the highly toxic pesticide active ingredient used in M–44 devices, also known as  cyanide bombs , and is used to kill coyotes, foxes, and wild dogs suspected of preying on livestock and poultry.
(2)
Sodium cyanide is registered for restricted use under the Federal Insecticide, Fungicide, and Rodenticide Act ( 7 U.S.C. 136 et seq. ) as a Category One acute toxicant, the most hazardous Environmental Protection Agency classification available, due to the harm it poses to people and the environment.
(3)
Poisoning by sodium cyanide leads to central nervous system depression, cardiac arrest, respiratory failure, paralysis, and blindness.
(4)
The Environmental Protection Agency authorizes the use of M–44 devices nationwide, and in recent years, M–44s were used in Colorado, Montana, North Dakota, Nebraska, New Mexico, Nevada, Oklahoma, Texas, West Virginia, and Wyoming.
(5)
In 2017, an M–44 device exposed an Idaho child to a sublethal dose of sodium cyanide with subsequent short-term and long-term medical complications. Two Wyoming children were also exposed to the poison from another M–44 device. Three family dogs died in these two separate incidents.
(6)
More than 50 family dogs have been documented as killed by M–44 devices since 1990, and the full count is estimated to be significantly higher.
(7)
The indiscriminate M–44 device commonly harms nontarget wildlife and people; at least 42 people have accidentally triggered a cyanide bomb causing exposure to cyanide gas and injuries since 1984.
(8)
A Utah man, who was poisoned by an M–44 in 2003 and permanently disabled, died in 2018 with cyanide poisoning from exposure to an M–44 device listed as a contributing cause of death on his death certificate.
(9)
M–44 devices kill targeted animals only 53 percent of the time. Thousands of nontarget species of animals have been killed by M–44s, including bald eagles, golden eagles, gray wolves, black bears, grizzly bears, bobcats, fishers, and family dogs.
(10)
Despite the United States Fish and Wildlife Service determining in 1993 that M–44 devices could kill endangered species like the California Condor, the use of the M–44 continues in areas where endangered species are found and continues to result in the deaths of endangered species.
3.
