Burning Flame Again Torrance Refinery April 2 2018
The battle over a highly toxic chemical used in oil refining recently received a fresh jolt, seven years later the substance became a regional crusade celebre in the wake of an explosion that rocked the Torrance Refinery.
That 2022 blast registered equally a small earthquake that shook nearby houses, injured four of the facility's workers – and covered the area in dust and ash. Merely the consequences, according to federal investigators, could take been far worse:
The explosion, investigators wrote in a report two years later, nearly released tons of modified hydrofluoric acid, potentially putting thousands in the South Bay at risk.
Refinery officials – those from ExxonMobil, which endemic the Torrance Refining Company during the explosion, and current owner PBF Energy – have repeatedly pushed back on that decision, maxim MHF doesn't pose a widespread threat.
But in the years since the 2022 explosion, residents take continued decrying MHF. Various elected officials have periodically attempted to rein in its use at the Torrance refinery and another in Wilmington, the only ii in the state that use the chemical.
All the while, officials at those facilities have defended the chemical's employ equally condom.
The latest salvo in the battle over MHF came last calendar month, when the Los Angeles County Board of Supervisors called for a ban on the highly toxic chemic.
Residents touted the move, introduced by Supervisor Janice Hahn and timed to the ceremony, while PBF, in a statement, criticized the county board's vote. Valero, owner of the Wilmington refinery, did non respond to multiple requests for comment.
The respective responses were predictable: For years, both sides of this boxing have zealously defended their positions.
Environmentalists and concerned residents say MHF could evidence catastrophic if the chemical were to escape, pointing to its corrosivity and studies that evidence its ability to travel beyond a refinery's footprint.
Refinery officials, though, say MHF was specifically designed to be safer than its not-modified original – hydrofluoric acid – and has been reviewed past experts and deemed the best catalyst for the refining procedure. In that location take also been multiple safety enhancements to prevent leaks, they say.
And those who run the Torrance facility also say its refinery hasn't experienced an off-site leak of either HF or MHF since it opened in 1966.
Economical factors, such every bit chore creation and the regional and global importance of oil, further complicate the issue, at least for elected officials.
Every bit a effect, unraveling the debate's complexities remains challenging. And and so, the battle over MHF's futurity appears set to linger on – with the Board of Supervisors' call for a ban the latest volley.
Explaining MHF
At the middle of that debate is the "modified" part of MHF.
For decades, hydrofluoric acid was a standard chemical in oil refining, serving as a catalyst during a process known as alkylation.
But HF is highly corrosive, posing a threat to nearby communities if information technology were dispersed as a gas during a burn down, explosion or the similar.
In the late 1980s, ExxonMobil and Phillips 66 jointly created modified hydrofluoric acid, which boasts a chemical additive that, when used in high plenty concentrations, can prevent the poisonous chemical from dispersing.
The additive does this by ensuring the chemic – used as a liquid during refining – doesn't turn into a gas.
Instead, if a leak occurred, a ground-hugging liquid cloud would form, according to a 2022 report from the Torrance refinery defending its use of the chemic. That, the study said, would forestall the chemical from dispersing as widely as it would as an aerosol.
In 2004, the South Coast Air Quality Direction District said much the same in an environmental assay the agency did when Valero introduced MHF at its Wilmington refinery.
"The modified HF goad reduces acid vapor pressure sufficiently to suppress the usual wink atomization process of hydrofluoric acid," that ecology bear upon report said, "causing near of the acrid to fall to the ground every bit an easily controlled liquid and reduces the potential for off-site consequences of an accidental HF release."
Environmentalists and activists, though, argue that the additive'southward levels in MHF accept significantly decreased since the modified version's cosmos.
MHF opponents have also expressed concerns that the refineries haven't washed enough to ensure the communities' safe.
At that place, as well, the Torrance refinery has disagreed.
"We are very proud of the many technical advances we have added to our Alkylation Unit over the years," the refinery says on its website, "which is additional proof of our continuing commitment to safety, reliable operations."
Those safety advances, nevertheless, have come since the 2022 explosion – and a harsh cess by federal investigators.
MHF takes center phase
In 2017, the U.S. Chemical Condom and Gamble Investigation Board published a 73-folio report on the explosion.
The explosion, the report said, launched a 40-ton piece of debris that nearly struck tanks carrying tens of thousands of pounds of MHF.
Had the tanks ruptured, the report said, it would have caused a massive release of MHF, which can be deadly to anyone who comes in contact with it.
Tests have shown that MHF, which Torrance has used since 1997, apace expands upon release and can travel at lethal concentrations upwardly to two miles, co-ordinate to a presentation from AQMD staff.
Both the PBF and Valero refineries are situated in densely populated areas of the Due south Bay: Most 245,000 people alive within three miles of the Torrance refinery and another 153,000 live inside that same distance of Valero's refinery, AQMD said. Thousands of people could take been harmed if the MHF had dispersed beyond the Torrance refinery in 2015, the CSB study said.
And the incident was avoidable, CSB said: Mismanagement and improper safety protocols put in place by then-owner ExxonMobil — who sold the refinery to PBF Energy shortly after the incident — made the explosion likely.
"This explosion and near miss should not take happened, and likely would not have happened, had a more robust procedure safety management system been in place," then-CSB Chairwoman Vanessa Allen Sutherland said in a statement at the time. "The CSB's report concludes that the unit was operating without proper procedures."
Only PBF Energy said otherwise.
"MHF was the subject of a thorough technology review by a court-appointed Safety Advisor with input from the Urban center of Torrance," Gesuina Lafayette, PBF's customs relations counselor said in a recent electronic mail. "The work of the Safety Auditor was overseen by a Los Angeles Superior Court gauge and approved prior to utilise of MHF at the refinery."
However, the explosion led to farther safety measures, some the refineries put in voluntarily and others they did so substantially at the bidding of regime agencies.
The explosion also spurred a movement among residents to oppose MHF. Those calls for a ban remain.
The debate, then and now
The move the LA County Board of Supervisors unanimously passed in mid-February asks Gov. Gavin Newsom and Attorney General Rob Bonta's offices to "accept all possible actions to require refineries in California to convert from MHF to safer alternatives."
The governor'due south office confirmed they received the request, simply declined further comment. Bonta'due south office said it hadn't received a letter from the county.
The motion also instructs canton departments to review existing health and safety measures related to MHF — including emergency precautions in example of an adventitious leak.
And it directs L.A. County to support whatsoever new legislation that would help stage out MHF.
"The 2022 explosion at the Torrance Refinery was bad, but information technology hands could have been catastrophic," Hahn said in a printing release. "We tin't assume nosotros will be then lucky next time, whether that is some other refinery accident, an earthquake, or God-preclude, an attack."
Lafayette pushed back.
"The passage of the Supervisors' motion is disappointing," she said in an e-mail, "because many of the points they make are both misleading and the projects are already in identify, following agreements with several government agencies to install boosted prophylactic measures."
The Torrance refinery, co-ordinate to its website, has made several improvements, including a leak-detection system, upgraded water monitors, 24/vii automated, continuously monitored unit of measurement cameras and an expanded h2o mitigation system. The refinery completed those improvements in 2020.
The improvements, though, besides came after sustained pressure from the community and watchdog agencies.
The fiercest local opponent of MHF is the Torrance Refinery Action Alliance.
The members of that alliance are locals.
Cliff and Donna Heise, for example, serve equally secretarial assistant and treasurer of the TRAA, respectively. They have lived in a neighborhood direct adjacent to the Torrance refinery for 48 years.
"We knew we were moving in side by side to a refinery — it was here before we were," Cliff Heise said in an interview. "Merely nosotros had no idea well-nigh the danger."
The couple was taking a stroll exterior of North Loftier School's football field on the mean solar day of the 2022 explosion.
By then, the husband said, they'd been living in the city long plenty to know exactly what the sound was.
Merely at the time, they'd never heard of MHF — and didn't remember much of it.
"Had we known then what nosotros know now," Cliff Heise said, "we would've run, not walked home."
Living in such close proximity to the refinery, Donna Heise said, makes it hard for the couple to ignore the chemic's potential dangers.
"When you think about information technology," she said, "it makes you non desire to sleep at nighttime."
After protests and intensified public pressure from such activists as the Heises mounted in 2017, the AQMD's Proposed Rule 1410 became a primal focus of the agency's Governing Lath.
The dominion would have required a gradual phase-out of MHF usage at both refineries, requiring an alternative catalyst, such as sulfuric acrid.
The proposal had plenty of support: Reps. Nanette Barragan, Ted Lieu and Maxine Waters wrote letters urging the AQMD to pass the rule and phase MHF out of Southern California. The LA County Department of Public Health and quondam California Attorney Full general Xavier Becerra followed suit.
The AQMD's own reports warned that the "ability of MHF to prevent formation of a vapor/aerosol cloud is highly uncertain" and that a "release of MHF will upshot in exposure to HF with the same health furnishings."
Simply the rule faced backlash also.
PBF, for its part, has repeatedly said concerns from local groups confronting MHF were unwarranted.
"For more than seven years, members of small, local activist groups accept been irresponsibly making claims against the Refinery's use of MHF, without whatsoever ground in fact," Lafayette wrote recently.
"They claim nothing has been done," she added, "without any proof, other than their beliefs, which are incorrect and misleading."
Other groups — including the refinery's unions and local businesses — feared the potential economic fallout if the refineries were forced to transition to a safer culling.
The AQMD estimated that replacing the MHF alkylation units with a safer sulfuric acid unit would cost the Torrance refinery about $900 million, and could temporarily impact gasoline supply and cost.
"The refineries aren't going to consume that cost," William Burke, former chairman of the SCAQMD'due south governing lath said in a previous interview. "They're going to pass it on to the consumer."
Merely the proposed ban on MHF is far from the showtime cost passed onto consumers:
The 2022 explosion, according to the CSB, caused the refinery to run at limited capacity for more than than a year and raised gas prices in California — costing drivers in the country an estimated $two.iv billion.
The Torrance refinery, however, also contributes significantly to the metropolis'south economy.
It provides 362 jobs — around $30 million in wages — in Torrance, according to its website. And Torrance receives about $7.5 1000000 annually in utility user taxes from the refinery'due south performance.
"The state could potentially lose thousands of jobs, and information technology could consequence in higher gasoline prices at the pump for California residents, businesses, and government," Californians for a Sustainable Economic system — an clan representing hundreds of local businesses — wrote in opposition to the ban. "Having affordable fuel that is readily bachelor is a vital part of the California economy."
The AQMD scrapped the potential ban in 2022 — instead accepting proffers from both refineries that promised to make safety enhancements to their existing MHF units.
Those safety enhancements, Lafayette said, include installing a new protective steel structure, water mitigation dome and curtain, an enhanced HF/MHF detection system, and additional water mitigation monitors.
Those improvements were completed in 2022 and are at present in service, Lafayette said.
PBF also reached a separate agreement with the U.S. Environmental Protection Agency to upgrade an additional water monitor in 2020, according to Lafayette. That update was completed final yr as well.
"We voluntarily enhanced the Alkylation Unit'due south robust, layered safety systems — already considered by experts to be amongst the virtually avant-garde in the globe," Lafayette wrote, "by installing additional safety enhancements."
Liz Odendahl, Hahn'southward spokeswoman, said in an interview that the supervisor was furious at the AQMD'southward decision to take the refineries' proffers.
Hahn — who left the agency's board in Dec 2022 — was ane of two votes opposed to accepting the proffers.
"The Supervisor knew the proffers were toothless," Odendahl said. "It'due south been a few years now, and there has been very niggling progress."
Hahn's February motion likewise asks the AQMD'south refinery committee to provide an update on the status of safety improvements listed in the refineries proffers.
The Torrance refinery "has completed all safety enhancements and Valero has begun installation of some elements of safety measures structures and additional implementation is ongoing," said SCAQMD spokesperson Nahal Mogharabi in an electronic mail. "The refineries are required to provide quarterly updates to the bureau."
The SCAQMD didn't comment on Hahn'due south request for the organisation to reexamine the viability of alternative technologies to MHF, some of which may exist more commercially bachelor than they were at the time of the vote.
Chevron, for example, successfully converted its Salt Lake City refinery from HF to a new alkylation engineering last yr.
Although at that place are alternative alkylation technologies under development, Lafayette said, "they yet need to be proven to be safe, mechanically reliable, and commercially viable at the scale of the Torrance Alkylation Unit."
Information technology's unclear what event these new calls to activity will have on the refineries' MHF usage.
But at least for at present, environmentalists and the refineries remain entrenched in their positions.
"With the addition of these voluntary safety enhancements and other obligations completed and operating, we have fulfilled our obligation to further protect Refinery personnel and the customs," Lafayette said. "The bottom line is Torrance Refinery now has the near advanced condom systems of any HF Alkylation Unit in California, the U.S., and the world."
The Heises, for their function, are still working to brainwash residents in Torrance and Wilmington almost their MHF concerns — and are grateful the issue is however being monitored.
"People," Donna Heise said, "are condign more enlightened — if goose egg else – over the last seven years."
And then, the battle volition linger on.
