This summer and fall the EPA has continued its marathon stakeholder outreach and listening process on its Clean Power Plan to clean up dangerous carbon pollution. The supplemental notice and new ideas that EPA issued for public comment on October 28th reflect EPA’s interest in hearing from all parties and getting the rule right. EPA also released a supplemental proposal to address carbon pollution from affected power plants in Indian Country and U.S. territories.
We'll continue pressing for the strongest carbon pollution standards to combat the threats posed by climate change
Supplemental Notice
The supplemental notice asks for comment on a number of new ideas EPA has heard from stakeholders. As EPA acknowledges, some of those ideas could tighten the standard, while others could loosen it, and some combinations of these ideas could bring better balance among the states’ targets. From NRDC’s standpoint, some of ideas presented are very promising and others are potentially troubling.
We will fully investigate the implications of what EPA is proposing and address them in our final comments to EPA by December 1st.
EPA is requesting additional comment on the following topics (see NRDC summary of the EPA proposal for a description of the existing Building Blocks):
The following are our high-level reactions to the new concepts and options EPA has raised:
These new concepts and options open the door to achieving greater equity and balance among the state targets, while achieving greater national emission reductions. In particular, EPA has identified ways to cost-effectively achieve greater emission reductions from coal-heavy states that were assigned weak targets under the June proposal. Of particular interest are the suggestions to account for under-utilized existing gas plants on a regional basis, rather than state-by-state, and to consider new gas plants and gas co-firing in coal plants. These options could yield more balanced and stronger state targets.
The notice also puts on the table revisions to the target-setting equation that would recognize the full emissions-reducing effect of increasing renewables and efficiency. Under the equation in the June proposal, increasing dispatch to gas correctly replaces megawatt-hours of coal generation. But new generation from renewables and energy savings from efficiency only add to, rather than replace, fossil generation. The new concept puts the Blocks 2, 3, and 4 resources on the same footing in the target equation.
The notice introduces a range of methods for calculating renewable energy goals, including regional approaches that would deliver more consistency across states.
Another potentially positive idea is consideration of multiple years of baseline data and possibly moving from 1- to a 3-year average for the baseline.
NRDC, however, is troubled by some of the new options:
The notice includes so-called “glide-path†options that would weaken or delay vitally needed near-term carbon pollution reductions promised by Blocks 1 and 2 under the proposal. The interim target in the Clean Power Plan is the lynchpin of the president’s Climate Action Plan to achieve a 17 percent reduction in overall U.S. carbon pollution by 2020. In turn, that commitment is critical to U.S. credibility and leverage in negotiations for comparable action from China, India, and the world’s other major carbon polluters. As our comments will show, there are plenty of options available to meet â€" indeed to strengthen â€" the 2020-2029 interim target proposed in June, as well as the target for 2030 and beyond.
Indian Country and U.S. Territories Supplemental Proposal
EPA’s supplemental proposal for the Clean Power Plan affecting tribal lands requires more review, but it appears to miss an important opportunity to reduce carbon pollution. In particular, we will be looking to see how the concepts introduced in the Notice of Data Availability would apply to the plants in Tribal jurisdiction. On first read, the supplemental proposal requires almost no emissions reductions from some of the most polluting coal plants in the southwest, creating a huge loophole for the regional utilities that own and operate the facilities. Those utilities have the same opportunities that are available in all states to reduce or offset the emissions of these plants through increased utilization of low emissions and non-emitting resources. While we acknowledge the economic challenges many tribes face, this pollution loophole is particularly ironic because the largest owner of one of these facilities, the 2250MW Navajo Generating Station located in northern Arizona, is the federal government itself.
Conclusion
We are optimistic that EPA has put enough new ideas on the table that the agency can address concerns from states and other stakeholders while also delivering final state targets that, on an overall basis, are stronger than the proposal and that keep the U.S. in a leadership position addressing carbon pollution from the electric sector.
