EPA's "Clean Power Plan" is not clean!

EPA logo

On June 18, 2014, the U.S. Environmental Protection Agency (EPA) published a proposed "Clean Power Plan" to reduce greenhouse gas emissions from existing stationary Electric Generating Units.  On December 1, 2014, Attorney Diane Curran submitted comments on this plan on behalf of thirty-two national and regional environmental organizations and Texas State Representative Lou Burnam.

A few of the comments include:

  • The EPA has set carbon emissions targets far below levels that are necessary to achieve meaningful and timely carbon reductions;
  • EPA's designation of natural gas and nuclear energy as "best system of emission reduction" (BSER) electricity sources is arbitrary and capricious;
  • Significant carbon emission reductions are demonstrably feasible and cost-effective in all U.S. states by using renewables and energy efficiency.

Sam Blakeslee Criticizes PG&E's Seismic Safety Report

December 3, 2014: Sam Blakeslee severely criticizes PG&E's report on the seismic safety of Diablo Canyon at a Hearing called by Senator Barbara Boxer. Blakeslee is the former leader of the California State Senate and earned a Ph.D. from University of California, Santa Barbara for his research in seismic scattering, micro-earthquake studies, and fault-zone attenuation.

Diablo Canyon in Peril?

Diablo domes

Former Nuclear Regulatory Commission senior resident inspector at Diablo Canyon, Dr. Michael Peck, argues that the plant should be shut down until

PG&E can prove that the reactors can withstand potential earthquakes from the nearby faults.


8/25/14 AP report: The Associated Press.

Dr. Peck's Differing Professional Opinion: document

Friends of the Earth:

In July of 2013, Dr. Peck filed a dissent over the NRC's decision to allow the reactors to operate despite newly identified seismic risks. The NRC's policy is to rule on such dissents within 120 days of filing, yet the NRC still has not ruled on Dr. Peck's opinion.

Senator Barbara Boxer, chair of the Senate Environment and Public Works Committee, announced that it would hold hearings into how the NRC has handled Peck's recommendation.

FOElogo.png8/26/14: One day after the release of the document suppressed by the NRC, Friends of the Earth filed a petition charging that the plant is in violation of its license.  "Citing the fact that the new seismic data shows that the reactors do not meet their licensing specifications and requirements and could therefore fail catastrophically in a massive earthquake, Friends of the Earth is asking that the NRC close the Diablo reactors and convene a public review with hearings to assess whether or not the reactors can be run safely and if so under what kind of revised license."

Take Action!
Tell NRC Chairman Macfarlane to shut down Diablo Canyon!
Friends of the Earth is circulating a letter urging Chairman Macfarlane to act. has a petition to the Nuclear Regulatory Commission demanding that Diablo Canyon be decommissioned:

Thirty-three environmental organizations filed jointly in opposition to the proposed rule. The filing also includes a petition to revise and integrate all environmental regulations related to spent fuel storage. Comments on NRC's Draft Wastestop nuclear wasteConfidence Rule were filed on December 20, 2013.

"The proposed rule marks a turning point for the NRC. After thirty years of making baselessly optimistic 'reasonable assurance' findings about the future availability of a disposal solution for spent reactor fuel, and having allowed many thousands of tons to accumulate at reactor sites around the country based on those findings, the NRC has finally stopped issuing them.  Instead of confidently assuring the public that human health and the environment will be protected from highly radioactive spent fuel as long as it remains dangerous, the NRC now claims only to have hope in a theoretical possibility."  READ THE COMPLETE DOCUMENT
