The BLM is a federal government agency that manages over 248.2 million surface acres of public lands and 700 million acres of subsurface, or mineral, estate in the United States.


The Energy Policy Act of 2005 prioritizes the energy industry over public interests in several ways, notably through the Halliburton Loophole.


Fracking is the process of using explosives and a highly pressurized mixture of water, sand, and chemicals to stimulate production from natural gas and oil wells.


The United States Forest Service (USFS) is an agency of the U.S. Department of Agriculture that administers the nation’s 154 national forests and 20 national grasslands, which encompass 193 million acres.


Ground-level ozone (sometimes known as “Smog”) in the Four Corners is an air pollutant formed from oil, gas, and coal emissions that threatens local public health.


Regional haze is the reflection of light off pollution particles in the air. Haze limits visibility from national parks and wilderness areas and threatens public health.


A split estate refers to property where the surface rights and minerals rights are owned by separate parties (federal, state, private, tribal, or corporate).
