POPP Act

HR 4038, the POPP Act, blocks the Environmental Protection Agency (EPA) from finalizing, implementing, or enforcing a specific proposed rule about greenhouse gas emissions from power plants. This rule, published in May 2023, aimed to set new standards for emissions from fossil fuel-fired power plants and replace an earlier rule. The bill prohibits the EPA from moving forward with this rule or any substantially similar rule, directly affecting the EPA's regulatory authority and power plant operators who would have been subject to the proposed standards. The bill bases this prohibition on arguments that the proposed rule violates the Clean Air Act by not demonstrating that required emission reduction technologies are commercially viable and cost-effective.
