The main purpose of this legislation is to abolish the Environmental Protection Agency (EPA) and transfer its responsibilities to state-level environmental quality departments. The goal is to give states more control over environmental regulations and funding, while also reducing federal oversight. Key provisions of the legislation include the complete dissolution of the EPA within 270 days of the law's enactment. All functions and responsibilities of the EPA will cease, and the agency will be required to wind up its affairs before this termination date.
