On February 9, the US Supreme Court issued a stay on EPA's Clean Power Plan in a 5–4 decision.
The US Environmental Prot from electricity-generating unection Agency (EPA) has announced a finalized Clean Power Plan to address greenhouse gas (GHG) emissionsits (power plants), or EGUs, under the Clean Air Act §111(d). The new EPA rulemaking addresses CO2, which accounts for 82% of US GHG emissions. The plan aims to lower carbon pollution from the power sector by 32 percent by 2030.
According to EPA’s Final Rule, made public on August 3, 2015, the new regulations focus on setting state-specific rate-based emissions limit for GHGs. In the rulemaking, EPA puts forth strategies already in use by states and companies nationwide to lower GHG emissions from existing power plants and:
The Building Blocks of Lower CO2 Emissions
- Improve efficiency at carbon-intensive power plants,
- Enhance generation from low emitting and renewable power sources, and
- Help homes and businesses use electricity more efficiently.
In the Final Rule, EPA provided three main criteria, called “building blocks,” to help State officials select a best system of emission reduction, or BSER:
1. Reducing the carbon intensity of generation at individual affected EGUs through heat rate improvements.
2. Substituting increased generation from lower emitting existing natural gas combined cycle units for reduced generation from higher-emitting affected steam generating units.
3. Substituting increased generation from new zero emitting renewable energy generating capacity for reduced generation from affected fossil fuel-fired generating units. What’s Next for Power Plants?
State attorneys general have already promised to file suit against EPA, stating that new clean power regulations are an overreach under the Clean Air Act. This approach has yielded some success already this year: In late June, the Supreme Court decided against EPA’s 2012 rules to limit emissions of mercury and other toxic pollutants emitted from coal-fired power plants in the case Michigan v. EPA
The new Federal clean power regulations delegate responsibility to each state to design and implement its own program for reducing CO2 emissions. Each state must submit a plan that, in part, identifies all affected entities in the state and describes the state’s plan to set, enforce, and report progress of CO2 emissions limits.
