PG&E revised its project this morning to
include only the survey of Box 4 in Estero Bay. The area is shown on map 2.2-1 on page 2-3 on the
Final Environmental Impact Report. Additional detail of exactly where the ship will be, to turn around and cover the area, is on map 2.5-7 on page 2-21.
PG&E asked the Coastal Commission to hear its application at the November 14-16 meeting in Santa Monica instead of the October meeting. Details will be posted on the
commission's web site.
While this is welcome news, the project remains devastating to the environment, with even less justification. The data that can be gathered from this small area will add little is anything to the knowledge of the threat of earthquake faults to Diablo Canyon Nuclear Plant.
posted a news story about it this morning:
Over objections of Central
Coast residents and environmental groups, Pacific Gas & Electric
plans to map earthquake fault zones near its Diablo Canyon nuclear plant
by blasting high-decibel air cannons under the surface of the ocean.
PG&E's plan calls for towing a quarter-mile-wide array of
underwater "air cannons" that emit 250-decibel blasts into the ocean
every 15 seconds for 12 straight days. The sonic reflections would be
picked up by underwater receivers and analyzed to provide detailed 3-D
images of the geometry, relationships and ground motions of several
fault zones near the Diablo facility, which generates enough energy to
meet the needs of more than 3 million Northern and Central Californians.
"What
we're after with this survey is the geophysical equivalent of a CT scan
— a combination of imagery and information that we could slice and dice
and scrutinize in great detail," said Jearl Strickland, director of
nuclear projects for PG&E. "These kinds of surveys are being
performed right now around the world with no problems."
Opponents say the method
threatens sea creatures from Central Coast rockfish to whales, and they
dispute PG&E's claims that there are no alternative, less harmful
technologies available for the job.
"We're not saying seismic
testing isn't needed," said Andrew Christie, director of the Santa Lucia
Chapter of the Sierra Club. "We want them to take the time to explore
potential alternatives that could do less environmental harm and provide
better data."
Of particular concern are potential effects at the
Point Buchon State Marine Reserve, a protected sanctuary, as well as on a
population of about 2,000 harbor porpoises that reside in and around
scenic Morro Bay. Harbor porpoises are acutely sensitive to manmade
sounds, which makes them especially vulnerable to hearing loss and
injury during the survey.
PG&E says environmentalists' fears
are unfounded. The utility acknowledges that environmental effects will
be significant and likely to include temporary displacement of most of
Morro Bay's harbor porpoise population. But PG&E says it believes
the survey's benefits outweigh the environmental costs. The California
Public Utilities Commission ordered PG&E to conduct the risk
assessment.
The utility initially planned to survey 90 square
miles of coastline for 30 days beginning Nov. 1. But facing questions
from state permitting agencies about potential environmental effects,
PG&E on Thursday scaled back the scope and duration of the project's
first phase to demonstrate its safety and effectiveness.
The
modified proposal would survey 51 square miles, stretch over 12 days and
focus on portions of the Hosgi, Los Osos and newly discovered Shoreline
fault zones in the Estero Bay area. It would not reach into the Point
Buchon area.
If all goes according to plan, the project will be
expanded next year to include two other areas targeted for surveys near
Diablo Canyon, including a portion of
Point Buchon.
The
California Coastal Commission plans to vote Nov. 10 on PG&E's
request for a coastal development permit needed to begin work offshore.
Later, the California Department of Fish and Game must accept or reject
PG&E's request for permits to harass, but not injure or kill,
protected fish and marine mammals in the survey area.
In a recent letter to the Coastal Commission, the
Natural Resources Defense Council
warned that approval of the permits would "set a harmful and legally
dubious precedent of allowing adverse impacts to the biologically
significant habitats and species in California's marine protected areas
in the absence of compelling public need to do so."
The
organization also argued that the survey is not essential to assessing
earthquake risks and is not likely to result in improvement in the
nuclear plant's safety. In a separate letter to the commission, the
Surfrider Foundation suggested that in-depth analysis of existing
seismic data and "worst-case-scenario models" would provide equally
effective emergency preparedness and response strategies.
Other
critics have suggested that PG&E use a larger vessel capable of
towing longer lines attached to 10, instead of four, geophone receivers
to record the echoes of the blasts. That way, researchers could cover a
wider area in a shorter period.
PG&E dismissed that idea
because a larger vessel would not be able to traverse relatively shallow
waters, which it says is essential to the study.
The survey was
scheduled for November and December to avoid the peak breeding seasons
of harbor porpoises and southern sea otters, as well the highest
densities of migrating blue, fin and humpback whales. Certified
"protected species observers" will be onboard vessels at sea and in
airplanes, on the lookout for injured animals and carcasses.
High-intensity blasts will be preceded by low-frequency sound waves
aimed at scaring off fish and marine mammals.
If a sea otter were
observed in the vessel's path, or a whale were spotted within a mile of
the operation, the air cannons would be shut down within seconds,
PG&E said. The number of southern sea otters in the proposed study
area is 352, according to the U.S. Fish and Wildlife Service.
The
death or injury of an endangered species would trigger an investigation
that could potentially result in prosecution, according to Christine
Patrick, spokeswoman for the National Oceanographic and Atmospheric
Administration.
"All those precautions might help animals that can
swim away," said environmental activist Julie Tacker of Los Osos. "But
what about those that can't, such as abalone, clams and starfish?"
Those
kinds of animals tend to congregate near shore and are not expected to
be affected by the air cannons, which would be pointed straight down in
water more than 75 feet deep, PG&E officials said.
Similar high-energy seismic surveys are planned for 2013 in coastal waters off
Southern California Edison's San Onofre Nuclear Generating Station in northern San Diego County.

Locally,
Matt Fountain of New Times covered the Fish & Game Commission meeting:
Pacific Gas & Electric took a verbal beating from the California Department of Fish and Game Commission
when the energy company went asking for a permit to conduct its
upcoming seismic studies, which will result in some degree of harassment
of local marine life populations.
On Sept. 24, the five-member
commission voiced concerns over the surveys, but admitted they have no
authority over whether department staff issues the permit or not.
Department staffers told New Times that
they’re holding off on finalizing the permit until a laundry list of
other state and federal agencies have had the chance to weigh in.
Following the roughly 40 people
who spoke before the commission against the proposed studies,
commissioners minced no words in voicing their opposition to expected
“take” of marine wildlife, as well as possible effects on marine
protected areas directly to the north of where the surveys are to take
place.
“It’s a marine life protected
area, not a marine life killin’ area. And as long as I’m here, we’re not
going to recommend to the department anything that’s killing anything
we’re trying to protect,” Commissioner Jim Kellogg told a cheering
audience.
PG&E Spokesman and Pismo
Beach Mayor Pro Tem Kris Vardas—abandoned by his fellow PG&E
staffers who left for another meeting—testified that the company is in
the process of spending approximately $4 million on a monitoring program
to make sure no wildlife is harmed, including an underwater
remote-operated vessel to scan beneath the waves for signs of injured
fish and marine mammals.
Should wildlife be found
injured or worse, operations would be shut down and investigated by the
U.S. Marine Fisheries Service, as the waters would essentially become “a
crime scene,” which goes beyond the scope of PG&E’s permit, Vardas
said.
The commission also seemed
baffled about what useful information the studies would glean, and how
it would contribute to the ultimate goal of improving understanding of
the seismic risk around Diablo Canyon nuclear power plant.
“I’m not convinced that nuclear
safety would be advanced, as some people have alluded to,” Commissioner
Michael Sutton said. “The only useful significant outcome I can see in
this is that it might give us sufficient information that the seismic
risk is so great that the plant should be decommissioned.”
The California Coastal Commission is expected to decide on whether to issue a coastal permit at its Oct. 10 meeting.
“I would encourage [the coastal
commission] to proceed with caution,” Commissioner Richard Rogers said.
“Any uncertainty of this magnitude is a very dangerous thing.”
Aside from the coastal
commission and the Department of Fish and Game, PG&E still needs
permits from the National Marine Fisheries Service, the U.S. Fish and
Wildlife Service, the National Science Foundation, the U.S. Army Corps
of Engineers, the Regional Water Quality Control Board, and the
California Department of Parks and Recreation before it may begin the
studies.
New Times cover story put the damage into visual terms.
Fountain also wrote about problems with the research vessel that will be hired to do the work:
It’s the same type of testing used to explore for offshore oil deposits.
According to the NSF’s Zacharias, the foundation has yet to solidify its contract with PG&E.
However,
both State Sen. Sam Blakeslee (R-San Luis Obispo)—whose legislation
mandated the studies—and county supervisor Bruce Gibson—who sits on the
project’s Independent Peer Review Panel to oversee its operation—have
been outspoken over their concerns about the Langseth not being “up to industry standards.”
The
vessel came into service in 2008, but has only been operating in its
current joint role as an academic-commercial seismic vessel for a little
more than a year, following several years of dry-dock and various
improvement upgrades. According to records of its stakeholder committee,
it’s encountered mechanical and environmental problems in the past, and
questions over whether it is fitted with the most up-to-date equipment
have come up.
The 2008 minutes of a Marcus Langseth Oversight Committee meeting features a laundry list of various mechanical improvements it needs to get in “working condition.”
According to minutes from 2010, the Langseth’s
operator reported marine mammals and smaller fishing vessels “snagging”
the towed arrays during a 2009 cruise. In a separate cruise that year,
the Langseth
was forced to de-obligate a $1.3 million contract when a
software-related problem caused an issue with the ship’s multibeam
following a supposed upgrade.
In
July 2011, the ship’s committee reported buying a new steamer and other
equipment from Western Geco—a company Gibson had urged considering for
the survey—worth a reported $5 million to $6 million, according to the
report. The used equipment was purchased for a mere $400,000.
“This is helping to bring the gear to more modern standards,” the report reads.
According to a December 2011 report, approximately $8 million has been spent on upgrading the Langseth since 2008.
Others have pointed out that the boat is owned by
the NSF, which is currently one of the agencies from which PG&E is
awaiting approval.
A Federal Register notice detailing PG&E’s
requested take was posted Sept. 19. Public comments will be accepted
until Oct. 15.
Given approval by the California Coastal
Commission—expected in mid-October—and the California Fish and Game
Commission, surveys are expected to commence in November.
