Drive east along Interstate 80, past the Phillips 66 refinery in Rodeo, and you can see that the Bay Area remains very much embedded in the fossil fuel economy. And if the U.S. Army Corps of Engineers has its way, we may well be doubling down on that relationship.

The Corps has a pending proposal, officially dubbed the “San Francisco Bay to Stockton, California Navigation Study,” to dredge a 13-mile stretch of the San Francisco Bay Estuary from San Pablo Bay (just north of Point San Pablo) through the Carquinez Strait to the Benicia-Martinez Bridge. This project would deepen the channel leading to four oil refineries along the shoreline by an average of three feet, allowing for the arrival of a larger class of oil tankers than can currently access these refineries. The Army Corps’ January 2020 Environment Impact Statement (EIS) for the project claims that the total volume of oil shipped will not necessarily increase as a result of the project, but rather claims that the dredging might even result in reduced ship traffic in the Bay by delivering the same amount of oil on fewer (but larger) ships.

This argument has not persuaded Bay Area environmental groups, who last spring submitted comments on the Draft EIS opposing the dredging project. These groups, including San Francisco Baykeeper, Sierra Club, Center for Biological Diversity, Friends of the Earth, Communities for a Better Environment, and Ocean Conservation Research, are submitting similarly negative comments on the Final EIS, which they say is not much of an improvement over the 2019 draft version. The deadline for public comments has been extended, due to the Covid-19 pandemic, until Tuesday, April 21.

The concerns of these organizations fall in to three basic categories: direct impacts on the local aquatic environment from both the dredging itself and from the increased traffic; direct air quality impacts on local communities from the increase in refinery operations; and above all, concern that increasing the capacity for delivery and production of fossil fuels directly contradicts the state’s mandated goal of reducing greenhouse gas emissions to slow the impact of climate change.

I. Impacts on Local Aquatic Environment

The Army Corps’ EIS contends that the Bay floor sediments to be disturbed by the dredging do not contain significant levels of toxic materials. But comments by the environmental organizations point out that the Corps appears to be relying on studies done over a decade ago or more, and they list a range of contaminants that could be re-suspended from the settled sediment that are not addressed by the Corps. The groups point out that this narrow body of water connecting the Bay with the Delta is heavily used by endangered fish species, including Delta smelt, longfin smelt, and Chinook salmon, among others, as well as by harbor seals and California sea lion, both protected marine mammal species.

The groups also point out that the EIS only addresses the impact of the dredging itself on the local aquatic environment. By asserting that the deepening of the channel will not, on its own, increase the level of shipping in the channel, the Corps disclaims any responsibility to address the impact of increased oil tanker traffic. However, as the environmental organizations point out, there is little chance that the refineries would not take advantage of this opportunity to increase their operations. In fact, as Ocean Conservation Research points out in its comments, the Phillips 66 refinery in Rodeo has recently been granted permission by the Bay Area Air Quality Management District to double its refining capacity. So it would be naïve to ignore the probability of increased traffic in the Strait, with is attendant increase in disturbance of all kinds (noise, water pollution, possible spills, etc.) and the resulting impact on wildlife populations.

In addition, Ocean Conservation Research’s comment letter points out that in order to accommodate the larger ships of the Panamax class (so-called because they are the maximum size allowed through the Panama Canal), the Phillips refinery has proposed an enlargement and expansion of its wharf facility. Such a project would involve disturbance of sediments full of toxic heavy metals left behind by the Selby Slag, a company that operated a smelter there into the 1970s, extracting ore from waste metals. Because the wharf expansion is considered a separate project, the Corps is not legally required to address it in its EIS — but expansion of the wharf would not be economically viable without the deeper channel.

Additionally, according to Baykeeper Executive Director Sejal Choksi-Chugh, “Baykeeper has concerns about how the project will impact salinity in the Delta. Deepening the shipping channel will push the fresh water/salt water mixing zone (known as the X2) further east, threatening drinking water supplies” for people in Contra Costa County and other Delta communities.

II. Impacts on Local Communities

Again, by asserting that the dredging project will not result in increased refining activity, and therefore only considering the impact of the actual dredging work, the Corps’ EIS does not find any impact on surrounding “environmental justice communities.” These communities, including Richmond, Vallejo, and Martinez, have been subjected to high levels of pollution from decades of industrial activity, and are demographically “majority minority” and low income. The failure of the EIS to contemplate increased levels of air pollution from increased refinery activities belies the refineries’ long record of “accidental” spills, flares, releases, etc. that have caused the area’s residents to periodically “shelter in place” long before the novel coronavirus.

III. The Big Picture

All of these local negative impacts are bad enough. But in their comments, the environmental groups assert that it is essential to step back and look at the much larger picture of what the dredging project implies for the region, the state, and the planet:

“The proposed channel alterations would remove constraints on expanding fossil fuel import and export volumes … The project will likely result in a significant increase in future volumes of crude oil and refined petroleum products shipped through the Bay … Here, the increased volume of oil and coal passing through the deepened channels will lead to greater refining and export activity. These in turn will lead to more greenhouse gas emissions, both at the refineries and when the products are combusted. Stated differently, the dredging is ‘a mere step in furtherance of many other steps in the overall development’ of the area’s fossil fuel industry.”

The environmental groups believe that the ultimate plan of the oil companies is to have the Bay Area’s refineries serve as an outlet for oil extracted from the Alberta tar sands, one of the most carbon intensive fuel sources on the planet, given the energy that must be invested to extract it, liquefy it for transport, and ship it. Moreover, the transport of this oil from its source in northern Alberta to the Bay Area is highly problematic, both politically and environmentally. It involves expansion of the controversial Trans Mountain pipeline over First Nation lands of the Salish people in Canada (a project that they are resisting both in the courts and on their land). Then the unrefined oil must be transported by tankers through the Salish Sea, threatening the already depleted Southern Resident population of killer whales. And finally, the tankers must pass through the Golden Gate, where recovering populations of humpback whales and gray whales are also facing increased threats from ship strikes in this busy shipping channel.

All of this leads to the final question of why U.S. taxpayers should fund (at an estimated initial cost of $57 million) a project whose main intended beneficiaries are privately owned oil refineries. Of course, direct taxpayer subsidies to the fossil fuel industry are nothing new, but in an era when we climate change requires us to be reducing our dependence on carbon-intensive fossil fuels, this project would appear to be moving us in the opposite direction.

From 2001-2017, David Loeb served as editor and then publisher of Bay Nature magazine, and executive director of the nonprofit Bay Nature Institute. A Bay Area resident since 1973, David moved here after graduating from college in Boston. The decision was largely based on a week spent visiting friends in San Francisco the previous January, which had included a memorable day at Point Reyes National Seashore. In the late 1990s, after many years working for the Guatemala News and Information Bureau in Oakland, David had the opportunity to spend more time hiking and exploring the parks and open spaces of the Bay Area. Increasingly curious about what he was seeing, he began reading natural history books, attending naturalist-led hikes and natural history courses and lectures, and volunteering for several local conservation organizations.
This was rewarding, but he began to feel that the rich natural diversity of the Bay Area deserved a special venue and a dedicated voice for the whole region, to supplement the many publications devoted to one particular place or issue. That’s when the germ of Bay Nature magazine began to take shape. In February 1997, David contacted Malcolm Margolin, publisher of Heyday Books and News from Native California, with the idea of a magazine focused on nature in the Bay Area, and was delighted with Malcolm’s enthusiastic response. Over the course of many discussions with Malcolm, publishing professionals, potential funders, and local conservation and advocacy groups, the magazine gradually took shape and was launched in January 2001. It is still going strong, with a wider base of support than ever.
Now retired, David contributes to his Bay Nature column “Field Reports.”

Allowing crude by rail is asking for trouble

By Kathy Kerridge, August 16, 2015, Benicia Herald

It’s time for Benicia and California to say no to bringing in crude oil by rail (CBR). This is the highly explosive and flammable Bakken crude from North Dakota, which exploded in Lac-Megantic, Quebec, killing 47.  This is what Valero wants to bring into Benicia and other refineries want to bring into the Bay Area.  There have been 30 major crude by rail accidents since 2012, including the latest on July 17 in Montana that spilled 35,000 gallons from a train that was going the legal speed limit.

The refineries also want to bring in tar sands crude from Alberta, Canada.  A spill of tar sands crude in water cannot be cleaned up.  The substances that dilute the tar sands (like benzene) so it can be transported evaporate and the tar sands sink to the bottom of the water.  $1 billion, yes that’s right billion, has been spent on the Kalamazoo River spill of tar sands and the river is still not clean.  Do we want a spill on the Benicia Rail Bridge into the Carquinez Strait or one in the Suisun Marsh?  How about the Feather River Canyon where a train carrying corn recently derailed sending its cargo into the river?

Say no to CRB going over high hazard areas.  Every rail line into the state goes through one.  Say no to CBR by earthquake faults.   Say no to trains carrying crude in cars designed to carry corn syrup.  Say no to the new cars which have also split and spilled in recent derailments.  Say no to bomb trains going through densely populated areas like Sacramento, Davis, and the East Bay.  Just say no to putting people, our water sources and our environment at risk

Valero Benicia sues BAAQMD, demands $57M in Clean Air Credits

Refiner Demands $57M in Clean Air Credits

By Dave Tartre, July 29, 2015 5:37 AM PT

SAN FRANCISCO (CN) – Valero Refining Co. sued the Bay Area Air Quality Management District on Monday, claiming it abused its discretion by denying it $57 million in emissions-reduction credits.

Improvements from a major modernization of Valero’s Benicia refinery brought significant and permanent reductions in air pollution, Valero claims, but the Air Quality Management District last year rejected its application to bank $57 million in emissions reduction credits for the work it did of its own volition.

The refinery, next to the Carquinez Strait about 25 miles north of San Francisco, emits fewer nitrogen oxides and less particulate matter greater than 10 microns in diameter than it did before the project, and also reduced organic compounds and sulfur dioxide, Valero says.

It claims that the Air Quality Management District has not disputed that “the emissions reductions were real, permanent, quantifiable, enforceable and not legally required.”

A Bay Area Air Quality Management District representative on Tuesday said the agency does not comment on pending litigation.

Valero says it relied on a senior district engineer for guidance during the project, only to find out that the district was not bound by her decisions.

After the project was complete, Valero says, the Air Quality Management District changed the baseline emissions figures for the before-and-after comparison it uses to grant or deny credits.

The district’s hearing board upheld the denial on appeal.

Valero on Monday asked the Superior Court to declare the ruling a prejudicial abuse of discretion not supported by substantial evidence in the administrative record.

Valero claims the district’s hearing board mischaracterized its 3½-year project as a “simple shutdown of equipment.”

To the contrary, Valero says, the refinery was outfitted with new furnaces, new flue gas scrubbers and other equipment that “reduced emissions of various pollutants … by thousands of tons per year, thereby significantly improving Bay Area air quality.”

Though the work was prompted by a 2005 consent decree with the U.S. Environmental Protection Agency, Valero says it went far beyond the agreement’s requirements, to retool the refinery’s equipment and operations.

Valero says that $500 million of the $750 million spent on the project went to “achieve emissions reductions beyond those required by the Consent Decree or by other provisions of law.”

Valero seeks writ of mandate to evaluate the fairness and consistency of the district’s rejection, not just whether it was reasonable.

A spokesman from Valero declined to comment, saying the company would let the filing speak for itself.

It is represented by Ronald Van Buskirk with Pillsbury Winthrop Shaw Pittman, in San Francisco.

Little known Concord fault poses threat to Bay Area refineries, Benicia-Martinez rail bridge…

Little known Concord fault poses big threat

CONCORD — A mysterious earthquake fault slices under central Concord, its jagged, quarter-mile-wide seam running beneath a critical fuel-pumping facility, traversing the edge of a refinery processing 166,000 barrels of crude oil daily, and undercutting strip malls and homes.

While its big sisters, the San Andreas and Hayward fissures, grab the headlines, the Concord Fault — with its 11-mile-long fracture zone stretching from the Carquinez Strait to the Mount Diablo foothills — is also capable of producing a catastrophic earthquake, geologists say. And with critical infrastructure in its path, particularly refineries and a vulnerable railroad bridge not far away, a large seismic event could leave the entire northern half of the state without easy access to fuel — disrupting transportation and the transmission of electricity and water, according to a recent study.

The Concord fissure may be largely ignored by the general public. But not by geologists.

“The Concord Fault is significantly more active than the fault that caused the Napa earthquake,” said Chris Wills of the California Geological Survey, referring to the 6.0 wine country temblor last August that caused more than $400 million in damage. “Nobody would be surprised if a magnitude-6 earthquake happened on the Concord Fault tomorrow.”

Make no mistake, Concord’s contribution to the Bay Area’s geologic activity is significantly smaller than the San Andreas and Hayward zones. Updated U.S. Geological Survey estimates indicate a 3 to 4 percent probability of a magnitude-6.7 or higher earthquake over the next 30 years on the Concord or lower Green Valley Fault, a connected Solano County segment, compared with 6.4 percent for the San Andreas and 14.3 percent for the Hayward Fault.

The Concord Fault creeps a measly 4 to 5 millimeters annually, while the Hayward slips 9 millimeters and San Andreas 25 millimeters.

The last catastrophic temblor on the Contra Costa-Solano combo fault struck more than 400 years ago, but geologists still say it’s important to monitor.

“At some point in time that system has to fail — we just don’t know exactly when,” said David Schwartz with the USGS. Even if the Concord Fault only produces a 5.0 quake, it could cause significant damage, Schwartz said.

The great unknown

On Oct. 23, 1955, a 5.4 quake — the Concord Fault’s last major temblor — was felt from San Jose to Sacramento. It caused $1 million in damage ($8.7 million in today’s dollars) and one fatality, according to the USGS. Windows shattered, brick walls cracked and moved, chimneys shifted and wine bottles crashed from liquor store shelves.

What makes the Concord Fault particularly worrisome to regional planners, so much so that it was highlighted in a December study by the Association of Bay Area Governments, is its potential impact on regional and statewide fuel distribution. Without gasoline, every other crucial need, including water, electricity and transportation, will be affected.

In its report, ABAG studied three theoretical earthquakes — a 7.9 on the San Andreas, a 7.0 on the Hayward and 6.8 on the Concord.

“Originally, we were just going to explore the San Andreas and Hayward faults, but we realized that (there are) a lot of key infrastructure assets in (the Concord) region,” said study author Michael Germeraad, an ABAG resilience planner.

Five Bay Area refineries — all but two are within a couple miles of the fault — processed 235 million barrels of crude in 2012, about 40 percent of the state’s total, according to ABAG. In addition, Kinder Morgan operates a pumping station nearby that receives processed crude from all the refineries and pipes it out to terminals across Northern California and Nevada.

Critical pipelines

That pumping station, a critical piece of fuel infrastructure, lies directly above the Concord Fault.

Built in the 1950s, the station receives products from eight facilities and pumps the refined crude through pipelines. It can store about 1 million barrels, but normal inventory is half of that, said Melissa Ruiz, a Kinder Morgan spokeswoman. Its five outgoing pipelines serve Chico, Fresno, Reno, Sacramento, San Jose, Stockton and surrounding cities, in addition to seven military facilities and public airports.

The company has facilities and pipelines in active fault areas throughout California but has never lost a pipeline or tank to a quake and maintains its infrastructure to industry rules and regulations, Ruiz said.

In its report, ABAG said it had concerns because pipelines can fail due to soil liquefaction — where hard soil loses strength during strong ground shaking — and fault rupture. Knowing pipeline material, age, weld types and other factors would help scientists know where failures are “more likely,” but that information isn’t available.

“Damage to the Concord station would interrupt fuel transmission across the northern half of the state,” the report concluded.

The study also found that if one Bay Area refinery was damaged, they would all likely suffer damage because of their close proximity to each other, and because they are built on similar soils and have similar construction.

“A conservative restoration estimate of damaged refineries is months,” the study found for the Concord quake scenario.

The Tesoro Golden Eagle facility in Martinez sits on 2,206 acres just feet from the fault. Built in 1903, Golden Eagle employs about 650 workers and is the fourth-largest refinery in California.

Spokeswoman Patricia Deutsche said refinery officials are aware it sits next to the fault and a liquefaction zone, but she said the facility follows industry design standards. Piles are driven down hundreds of feet into bedrock, equipment has been retrofitted and the Avon Wharf, an oil terminal located on aging timber piles along the southern shore of Suisun Bay, just received environmental clearance for retrofit up to state quake standards, she said.

Seismic assessments of Bay Area refineries are done every five years, and the building code requirements consider the level of possible ground shaking from any nearby fault, said Gayle Johnson, senior engineer with Simpson Gumpertz & Heger, a national engineering firm.

Johnson, who has investigated the performance of industrial facilities in more than 20 earthquakes worldwide, said since the refinery retrofit programs began in the late 1980s and early 1990s, there has been a “ton of upgrade work done.”

Other impacts

While fuel infrastructure may be the top concern for the region, a large quake could disrupt other major lifelines. The Benicia-Martinez rail bridge, located between the two vehicle spans, is particularly vulnerable, according to ABAG, and could face “significant or complete damage.”

Liquefaction along the Carquinez Strait could cause dredged water channels to slough into the shipping pathways. Runways could rupture at Buchanan Field, which sits adjacent to the fault. Delta levees could breach, creating flooding and impacting drinking water quality, ABAG found.

Two-thirds of the power generated in the region is produced by natural gas facilities, many along the Carquinez Strait.

“In the event natural gas lines are damaged, these facilities will be unable to generate electricity,” the study found.

Still, Wills warns that what will happen during a significant quake on the Concord Fault is largely a mystery.

“How it releases is not that well known,” he said.
