Representative Jeff Miller (R-FL) sponsored H.R. 4089, the so-called Sportsmen's Heritage Act of 2012, which would threaten the conservation of fish, wildlife, and habitats that benefit all Americans, including conservationists and sportsmen. H.R. 4089 would roll back long-standing environmental laws like the National Environmental Policy Act and the Wilderness Act, and it would reduce or eliminate important protections for America's public lands, allowing widespread motorized access to wilderness areas and opening up units of the National Park System to hunting. The bill would weaken the Environmental Protection Agency's authority to regulate lead and other toxic substances used in ammunition and add an exemption for any chemical used in fishing equipment, despite the widespread availability of affordable and effective alternatives to lead bullets and sinkers. Additionally, the bill would allow for the importation of polar bear trophies from Canada under newly-created exceptions to federal law, which could encourage hunters to kill protected species in other countries, store them in warehouses, and then later seek legal waivers from Congress. On April 17, the House approved H.R. 4089 by a vote of 274-146 (House roll call vote 164). NO IS THE PRO-ENVIRONMENT VOTE. The Senate took no action on this legislation.
