Two Parts of Valero’s Benicia Refinery Under Scrutiny in Probe of Pollution Releases

Two key components at the Valero refinery in Benicia experienced problems earlier this month, leading to weeks of releases of petroleum coke dust that intensified on Sunday, culminating in the shutdown of a large portion of the facility.

The new details on the refinery’s malfunctions are laid out by Valero in a preliminary report filed with Benicia city officials this week.

The malfunctions are the focus of at least one part of an investigation by Solano County inspectors into an incident that led to health concerns for people living near the refinery and to a statewide spike in gasoline prices.

Valero’s report says that the recent problems at the refinery began March 11 when a crude oil processing unit called a fluid coker experienced “operating difficulty.”

Normally, a fluid coker heats up and “cracks” the thickest, heaviest components of crude oil processed at a refinery, breaking them down into material that can be used in diesel or other petroleum products. One of the byproducts of the process is solid carbon residue called petroleum coke.

The problems with Valero’s fluid coker unit allowed petroleum coke dust, called coke fines, to flow to a second unit called a flue gas scrubber. The scrubber cleans out fine particles before they’re released from the refinery’s smokestacks into the air. That process is supposed to ensure that the refinery’s emissions don’t violate air quality standards.

But the coke fines moving through the scrubber unit set the stage for a release of particulate pollution from the refinery — a release that was clearly visible from outside the facility.

“The presence of coke fines in the FGS resulted in a darker than normal plume appearance,” Valero’s 72-hour report said.

Solano County investigators want to know if the scrubber was somehow overwhelmed or damaged, according to Terry Schmidtbauer, the county’s director of resource management.

“We know something’s not operating properly,” Schmidtbauer said.

California’s Division of Occupational Safety and Health Cal/OSHA and the Bay Area Air Quality Management District are also investigating the refinery.

After the problem surfaced, the air district issued eight notices of violation against Valero for public nuisance and visible emissions.

Refinery crews worked to reduce the releases and Valero said the situation showed “significant improvement” by last Friday, when the plume coming from the refinery’s stacks “returned to normal appearance,” Valero’s report said.

But that changed the next day. The scrubber “experienced an operational upset resulting in a dark, opaque plume and emissions of particulate matter,” the report said.

A new surge of petroleum coke dust billowing from the refinery’s stacks prompted Benicia officials to issue a health advisory, urging people with respiratory issues to stay indoors.

The refinery began to shut down several units, and the air district wound up issuing four more violation notices.

The powering down of the the facility is contributing to an increase in gasoline prices.

On Friday the average cost of a gallon of unleaded gas in California jumped to $3.59, up 16 cents from a week ago, according to AAA.

Energy analysts and state regulators say the price will continue to rise until operations at Valero return to normal.

Local renewables in the US ‘make more financial sense than coal’

A new report suggests three-quarters of US coal-fired generation could be replaced with local wind or solar power at cheaper cost to the consumer

Local renewables in the US now make more financial sense than coal.

That’s according to a new report from renewable analysis firm Energy Innovation, which suggests in 2018, three-quarters of existing US coal-fired generation could have been replaced with wind or solar power within a 35-mile radius at an immediate saving to customers.

It predicts by 2025, this figure will grow to 86% of the coal fleet as fossil fuel generation becomes increasingly uneconomical and the cost of renewable power continues to fall.

The report suggests this is happening as the ‘all-in’ costs of new wind or solar projects become cheaper than the combined fuel, maintenance and other ongoing costs of coal-fired power.

In 2018, 94GW of existing US coal capacity was deemed ‘substantially at risk’ from new local wind and solar – by 2025, the study expects ‘substantially at risk’ coal to increase to 140GW, almost half the national fleet.

It recommends local decision-makers should consider plans for a smooth shut-down of these old plants, replacing them with technologies such as wind, solar, transmission, storage and demand response.

It notes replacement infrastructure must be reliable and affordable for communities dependent on existing coal plants.

The report reads: “The purpose of this report is to act as a conversation primer for stakeholders and policymakers where the math points to cheaper options that could replace coal plants at a savings to customers.

“Regardless, any coal plant failing the cost crossover test should be a wake-up call for policymakers and local stakeholders that an opportunity for productive change exists in the immediate vicinity of that plant.”

Government deregulation without limits – FAA comes under criticism

Deregulating? DeFazio’s watching

Posted Mar 27, 2019 at 12:01 AM

The Boeing 737 jet crashes raise troubling questions that go far beyond one company’s safety record and one federal agency’s watchdog role.

The history of the Boeing 737 MAX 8 aircraft suggests it is an example of how the government’s regulation-and-oversight pendulum has swung too far. The Federal Aviation Administration has lacked both the money and the inclination to adequately oversee aircraft development, instead relying heavily on companies to do their own testing.

Oregon Rep. Peter DeFazio is demanding answers. The Springfield Democrat chairs the U.S. House Transportation and Infrastructure Committee. The committee’s investigative staff is doing research, and DeFazio then plans to hold hearings.

“This is really, really raising questions about the FAA as a watchdog,” he said in a meeting with The Register-Guard editorial board.

A faulty sensor is being investigated as one cause, and Boeing is working on a software fix. The two-sensor system was developed as a safety feature to prevent a plane from stalling. But it appears the failure of just one sensor can send the aircraft into a powerful, possibly irreversible dive unless the pilots override the system within 40 seconds, according to a New York Times report this week.

DeFazio promises a tenacious investigation. Among the questions are why the system was designed this way, whether the aircraft was unsafely rushed to market, and why the FAA and Boeing did not require extensive retraining of pilots.

“This is the first time Boeing has put in a system that took over the plane automatically,” he said. “And they didn’t think they needed to tell people about it — because it’s different from any other Boeing plane ever made?

“Obviously, maybe not the best idea.”

For years, the FAA has lacked sufficient inspectors and has outsourced much of that responsibility to the manufacturers. But the FAA is not unique. We now have a government that relies on the honor, integrity and self-supervision of the industries it regulates.

When something bad happens, the government will take action — but over time those regulations and requirements wind up being dropped, reduced or delayed. The 2017 fatal Amtrak derailment near Tacoma, the 2016 oil train derailment in the Columbia River Gorge, the 2010 Deepwater Horizon oil disaster in the Gulf of Mexico, the 2008 financial crisis and countless other events could have been prevented.

“It’s repeated time and time again,” DeFazio said. “There are limits to deregulation, which in many cases have been exceeded.”

Oregon has its own history of unwatchful eyes. The Cover Oregon health insurance fiasco could have been averted through closer, more-knowledgeable oversight and insistence on stronger testing of the technology throughout its development. Better oversight — not to mention much-better planning in the first place — might have saved the state from wasting millions of dollars in the Highway 20 reconstruction between the valley and the coast.

Each time, government and the public vow to learn from these lessons. Then we relax and we forget.

When DeFazio and his congressional colleagues find the answers they are seeking, our government should heed them.
