Settlement Announced in Suit Challenging Nuclear Fuel Storage at San Onofre

ROSEMEAD, Calif.–(BUSINESS WIRE)–The parties in a lawsuit challenging the permit which allows for
temporary storage of used
nuclear fuel at the San Onofre nuclear plant have settled the case
and will not proceed to hearing on Sept. 8, as scheduled.

In a filing
today with a San Diego Superior Court judge, the parties acknowledge a
shared interest in relocating San Onofre’s used nuclear fuel to an
off-site facility. The parties to the settlement are Southern California
Edison, majority owner of San Onofre, and plaintiffs, Citizens
Oversight, Inc. and Patricia Borchmann, represented by attorneys Michael
Aguirre and Maria Severson. The California Coastal Commission, which
issued the permit in 2015 authorizing expansion of on-site storage of
used nuclear fuel, is the defendant in the suit.

The settlement agreement details multiple steps SCE will take in support
of its efforts to move San Onofre’s used nuclear to an off-site
location. In light of SCE’s commitments, plaintiffs have requested a
dismissal of the lawsuit. Here is a summary
of the settlement.

“A cooperative effort between the public, independent experts and
Southern California Edison has begun and will continue until the nuclear
waste is removed from San Diego,” said Aguirre. “We are thankful SCE
worked hard to reach this common goal,” added Severson.

“The agreement plots a prudent strategy in furtherance of the goal of
moving the fuel sooner than later,” said Ray Lutz of Citizens Oversight.

“SCE is proud to take a leadership role in what we expect will become an
industry-wide effort over many years to work with the federal government
and other key stakeholders to achieve off-site storage,” said Ron
Nichols, president of SCE. “We will be vigilant in our efforts to prompt
the federal government to act, and until we can secure off-site storage,
will continue our 30-year track record of safely storing used fuel at
San Onofre.”

The suit was filed in November 2015 after the coastal commission granted
SCE’s permit to expand on-site storage of used nuclear fuel at San
Onofre. One-third of San Onofre’s used fuel is currently in dry cask
storage and the remaining two-thirds is stored in steel-lined concrete
pools. In order to facilitate the safe decommissioning of the plant, SCE
plans to move the fuel from the pools into dry storage by 2019, where it
would remain until an off-site storage facility is available.
