Topline:

The rendering company Baker Commodities in Southeast L.A. — which recycles animal parts and carcasses into materials for everyday products — was the focus of years of community odor complaints before being shuttered by the South Coast Air Quality Management District (AQMD) for nearly nine months.

Where things stand: The company has since partially reopened after meeting with the agency’s regulatory panel. Baker is suing AQMD for $200 million in damages and an upcoming court decision could allow it to fully reopen.

Why now: In a new investigation out today, LAist spoke with dozens of local residents and reviewed odor complaint records, violation records, notices to comply, and inspection reports to piece together how the rendering of dead animals at Baker has impacted surrounding communities.

KEY FINDINGS AT A GLANCE

A small region of Southeast L.A. is home to a disproportionate number of plants that handle the rendering of animals, hazardous wastes and other manufacturing that creates health hazards. It also has startlingly high rates of cancer-risk and other ailments
In the small city of Vernon alone, or very nearby, there are six slaughterhouses, four companies licensed for rendering, and at least 40 meat processors, according to an LAist review of state and federal licensing and inspection data.
Interviews with longtime Southeast L.A. residents and workers, and data obtained through public records requests, show that neighbors have complained for decades about adverse effects — including putrid odors that burn people’s eyes and throats and led students to want to go home from school.
One company, Baker Commodities Inc. is now at the center of a fight that underscores competing interests of industry, health and quality of life in a densely populated region where more than one in five people live at or below the poverty line.
Conditions at that Vernon facility were described by one inspector with the South Coast Air Quality Management District, which is responsible for holding businesses accountable to the law, as smelling “intensely of rotting animals.” He said in a sworn written statement filed in court that the first time he inspected Baker he wanted to vomit.
Some environmental justice advocates are asking why the company is suing regulators for $200 million in damages rather than addressing systemic issues identified in numerous inspections.

Tucked along Bandini Boulevard in the city of Vernon are the headquarters for Baker Commodities Inc., a company that employs 900 workers across the U.S. and is home base for some of the grisliest industrial work in the country.

Behind the nondescript walls of its campus along the L.A. River sit machines used to grind, cook, and press leftover pieces of cows, pigs, and chickens. These remains — and, sometimes, entire carcasses — are delivered on semitrucks from butcher shops, grocery stores, restaurants, slaughterhouses and livestock farms. A worker then pushes them into a pit with a tractor and, through a process called rendering, they’re turned into fats, meat and bone meal, and hides.

These materials are recycled to make scores of everyday products, including soap, pet food, makeup, and leather goods. The long-running industry plays important roles in reducing food waste.

For decades, residents in surrounding neighborhoods have complained of putrid dead animal smells. In 2017, community pressure compelled the local agency that oversees air emissions, the South Coast Air Quality Management District (AQMD), to adopt a rule to mitigate odors from Baker and a handful of other rendering plants. Among other requirements, the rule forces these companies to post signs indicating where residents can report odor issues — a demand some plants lobbied against. Then, in September 2022, the agency shut down Baker, citing repeat violations of its odor mitigation rule.

At the time, community members and elected officials celebrated the closure as a win. But what many don’t know is that the company has partially reopened and is waging an intense legal battle against AQMD. After AQMD shut it down, Baker filed a lawsuit against the AQMD in L.A. County Superior Court. Baker claims the company was not in violation of the odor mitigation rule and that it was treated unfairly. Baker also demands that the shutdown order be tossed out and aims to bar air regulators from shutting it down in the future.

LAist spoke with dozens of local residents and reviewed odor complaint records, violation records, notices to comply, and inspection reports to piece together how the rendering of dead animals at Baker has impacted surrounding communities.

We found:

Since the odor mitigation rule went into effect in 2017, AQMD has issued 12 violations and five notices to comply to Baker. Eight of them were for violating the odor mitigation rule. The rest were for failing to comply with permit conditions and other requirements. Three of the violations are still pending.
LAist found 111 odor complaints identified by the person reporting the smell or by AQMD as being tied to Baker between August 2019 and late last week. These complaints came from homes, local schools, and businesses near Baker’s headquarters.
Baker failed to store animal remains within four hours of delivery, leaving them out to fester and violating AQMD’s rules, according to the agency’s attorneys — and it did so six times between August 2019 and January 2022.
An AQMD inspector reported Baker violated AQMD rules that require surfaces exposed to animal matter to be washed down at least once per working day, according to his sworn written statement filed in Baker’s court case. The inspector said he saw strings of animal matter dangling on grates at the company’s headquarters.
In Baker’s unloading zone for animal remains, broken concrete or asphalt was present in March and April 2022, according to AQMD’s attorneys — a problem that officials at the agency say can cause water to pool and smells to fester.

We should note that Baker has disputed AQMD findings in the latter three items in court filings.

In the year since AQMD ordered Baker to shut down, residents say the odors are less intense and less frequent — and AQMD complaint records associated with the company show a dramatic drop in reported smell problems. The shutdown lasted nearly nine months, until the company petitioned the hearing board and was granted permission to work in a limited capacity, doing trap grease and wastewater treatment — but not rendering animals.

Many community members were worried to learn from LAist that the court may allow the company to fully reopen and return to rendering livestock and poultry without making long-term changes to the way they operate.

About Baker Commodities

Baker is one of roughly 200 rendering companies in the U.S. and is part of an industry that dates back to the 1800s and currently generates $10 billion annually.

Aside from its headquarters in Vernon, the company has more than a dozen locations across the U.S., including Las Vegas; Rochester, New York; and Kapolei, Hawaii.
In addition to rendering animals, the Vernon facility processes trap grease and wastewater. Trap grease comes from devices that capture fats, oil and grease in restaurant kitchens, to keep them from entering the sewer system.
At its Vernon headquarters, according to court filings, Baker collects and treats 21 million gallons of grease trap water per year that it neutralizes before it enters the sewage system.

A long track record of problems, a fierce fight to stay in business

A review by LAist also uncovered details of the steps Baker has taken to try to get back to running at full scale in Vernon. The rendering company submitted 125 legal filings in its battle against AQMD over a 12-month period, arguing that it’s in compliance with the odor mitigation rule. In that time, it’s had two law firms working the case, which calls for $200 million in damages from the government agency for lost revenue, the disclosure of trade secrets and other items. Its current legal team at DLA Piper — a top-ranking, multinational law firm — includes Angela Agrusa, who specializes in brand-crisis litigation and has represented comedian and actor Bill Cosby and Chipotle, among others.

“The fact that Baker Commodities would come at an agency that is really intended to protect the public's health is not just unfortunate, but it is despicable,” said Angelo Logan, who grew up in the nearby city of Commerce and returns weekly to visit his mother. Logan currently serves on the White House Environmental Justice Advisory Council and learned of the litigation from LAist.

Cudahy Councilmember Elizabeth Alcantar, who lives about 3 miles away from Baker, was also unaware of the legal fight until LAist’s reporting.

“It’s absolutely concerning to see that happen,” she said.

Alcantar grew up in Cudahy and says she and her family have endured the stench of rotting flesh for as long as she can remember. She was shocked to hear Baker is pursuing legal action that will cost taxpayers money, instead of addressing community concerns.

“It's going to take AQMD's time and funds away from what they should be doing, which is enforcement,” Alcantar said of the litigation, explaining that the community has been under duress for years due to foul odors. “[W]e are here, simply wanting to breathe clean air.”

Baker’s assistant vice president of public relations and legislative affairs, Jimmy Andreoli II, declined multiple interview requests. Agrusa, Baker’s lead attorney, did not respond to our requests for comment.

In an emailed statement Andreoli said, “While we cannot comment on active litigation, we are dedicated to finding sustainable ways to support California’s food production and restaurant industries with continued strict adherence to local, state, and federal environmental laws.”

“Some of our business operations have been approved to resume,” said Andreoli, who is the grandson of Baker’s 96-year-old CEO, James Andreoli. Jimmy Andreoli II added that they look forward to finding long-term solutions with AQMD.

Baker’s lawsuit against AQMD is still pending. Later this month, if a settlement isn’t reached beforehand, an L.A. Superior Court judge is scheduled to decide whether the rendering company can reopen at full capacity. The judge will also rule on the $200 million in damages Baker is seeking, as well as its call to keep AQMD from shutting it down in the future.

If Baker succeeds in court, interviews with community members suggest it could further erode the relationship between the city of Vernon and local residents across Southeast L.A., many of whom are grappling with odors on top of other environmental issues.

A company with big problems

Many people who live in or near Vernon have no idea that they live close to four rendering plants that process everything from fat, to livestock, to the remains of cats and dogs. The city, which is just 5 square miles in size, is also home to at least 40 meat processors, which buy meat from slaughterhouses to prepare items found at grocery stores, like sausages and steaks. There are also six slaughterhouses within 1 mile of Vernon’s city limits .

At some places, silos and smokestacks hint at what’s happening inside, along with flocks of seagulls hovering far from shore. But, for the most part, these businesses are tucked behind bland metal sheets and concrete walls.

Baker itself is sandwiched between the L.A. River and several train tracks. The rendering company has been in Vernon since the 1940s. But after AQMD determined that Baker blew a deadline to seal off its rendering operations to keep potential odors from escaping in spring 2022, the agency’s legal counsel moved to shut it down.

AQMD’s hearing board, which enforces the agency’s regulations, gathered to vote on the shutdown in September of 2022. Before reaching a decision, the board held a hearing, which LAist found little media coverage of at the time. It provided a rare look inside Baker’s headquarters.

Over a span of three days via Zoom, attorneys for both parties peppered an AQMD inspector with questions.

In 2022 inspector Dillon Harris testified that he visited Baker nine times. He documented hooves and other animal bones strewn across the floor, overflowing from a large trash bin. He spotted a trough with built up blood, animal fat, and wastewater. He said he saw staff dumping sludge — a thick, pancake batter-like mix of liquid and solid animal remains — from trucks into open-air pits. Baker, he said, also left equipment doors and panels open, which are supposed to be kept shut to trap possible smells, and employees dumped expired clams, shrimp and ground beef into an exposed container.

During the hearing , dozens of photographs capture Baker’s facility.

In them, rib cages can be seen among a heap of animal parts, pools of blood-colored liquid are shown in multiple locations, a drain is backed up and surrounded by dead animal debris. Harris, the inspector, also captured images of raw animal material leaking out of the rendering equipment. Baker has argued that photos shown during the hearing should be sealed from the public’s view because they contain trade secrets that competitors can now access.

Baker later filed an emergency motion asking a Los Angeles Superior Court judge to restrain the AQMD from publishing the inspector's photos and to take them down from AQMD hearing board videos on YouTube. The judge denied it in October 2022.

The Andreoli family, which has owned Baker since the 1980s, spoke at the hearing and disputed Harris’ findings. Jimmy Andreoli II said he visited the Vernon facility a week earlier and saw “a wash truck that was moving throughout the facility and washing down various roadway surfaces.”

Baker attributed some of the inspector’s findings to human error. Jason Andreoli, who was identified at the hearing as Baker’s general manager, said the company put up signs reminding staff to keep the doors closed. “And we also put a policy in place that if they are left open, there’s gonna be disciplinary action,” he said.

Several hearing board members appeared mystified by Baker’s claims that the company was in compliance with AQMD rules.

"Every picture virtually that we see is of equipment that is absolutely filthy," said the late Dr. Allan Bernstein, one of the hearing board’s voting members who died last spring.

"It's mind-boggling to sit here and see anyone try to defend this position when we're all looking at these pictures with our eyes," he added.

During closing statements, AQMD attorney Daphne Hsu said she understood the magnitude of shutting down the company. “We don’t ask a facility to stop operating lightly,” she said, noting Baker could have proposed a timeline to come into compliance. Instead, she said, the company chose to dispute the agency’s findings.

“Baker must be in compliance before it restarts,” Hsu added. “The community has waited long enough.”

The hearing board voted 4 to 1 to shut down Baker. That’s when the court battle began.

'I had to step away because I almost vomited’

When AQMD implemented the odor mitigation rule in November 2017, rendering facilities that had to comply were given 90 days to meet basic standards. The goal of the rule was straightforward: to keep potential odor sources contained and protect people living nearby. The rule requires steps like washing down surfaces at least once a day and repairing cracks in the asphalt to keep pools of odorous bacteria from forming.

“As they're bulldozing and pushing all these raw carcasses, [the animal remains get] smeared across asphalt and concrete, and odors start developing,” explained Wayne Nastri, AQMD’s executive officer, in an interview with LAist. “What the rule actually intended to do was to control the process the whole way, to minimize [animal remains’] exposure to the air that would generate those kinds of odors.”

AQMD gave renderers subject to the rule up to three and a half years to install enclosures, or bring all their operations into a closed system indoors, to keep odors from drifting off site. Some asked for extensions before they finished the work, but, according to AQMD, Baker is the only one that has not complied. In its lawsuit, Baker repeatedly argues it is in compliance.

When Harris, the AQMD inspector, checked out Baker for the first time after the rule went into effect in 2018, he remembers being disgusted.

“I had to step away because I almost vomited,” he said in a sworn written statement filed with AQMD’s response to Baker’s lawsuit.

Recalling the inspections he conducted at Baker in 2022, Harris added that: “The odor at the facility smells intensely of rotting animals.”

His work boots, he explained, were so soaked through with the smell of rendering that he couldn’t use them at non-rendering facilities. In one of Baker’s rendering plants at its Vernon campus, he said “rotting odor emanates from all sides.”

L.A. County Supervisor Janice Hahn’s district includes Vernon — she advocated last year for Baker’s shutdown.

“It was clear that Baker Commodities had long violated air quality rules and had done little to nothing to come into compliance,” she said in an emailed response to questions from LAist. “It was time for [AQMD] to uphold the rules they had on the books and protect the community from this company."

Nastri, AQMD’s executive officer, declined to speak on Baker’s lawsuit, citing pending litigation. Court filings show AQMD has hired two outside law firms to work the case, in addition to the agency’s in-house attorneys. They’ve filed a cross-complaint against Baker, demanding that the rendering company pay $10,000 per day for each of its violations.

Nastri confirmed to LAist that Baker has committed the most violations out of any of the rendering plants in its jurisdiction.

The air pollution agency’s rules “are there to ensure that we have a level playing field,” Nastri said. “And to all those companies that are making the investments, that are operating in conditions that they're supposed to operate, it's unfair if we were to let others who do not make those investments and seek to profit off of the lack of compliance — that's just wrong.”

“We are very consistent and very strong in our enforcement approach,” he added. “And so long as those companies continue to violate those rules or regulations, we will go after them. Period.”

How odors impact community members’ daily lives

Residents of Southeast L.A. County, as well as Boyle Heights and unincorporated East L.A., have put up with rendering plant odors for years. And Baker is not alone — odor complaint records reviewed by LAist show the three other nearby rendering plants have also generated concerns.

So have other businesses. The city of Vernon is home to just 222 residents and is almost exclusively industrial — nearly 600 of its businesses handle or store hazardous chemicals, according to a city report. Local residents have lodged complaints with AQMD about strong garbage odors from trash collection companies, as well as nauseatingly sweet smells from flavor and fragrance suppliers. One resident complained their neighborhood reeked of “melting Jolly Ranchers.”

Shifting wind patterns near Vernon add to the challenges. According to Terrence Mann, AQMD’s deputy executive officer of compliance and enforcement, an odor can start off in Monterey Park, “then, just a few minutes later,” pop up in Huntington Park — about 11 miles away.

Interviews with local residents , as well as odor complaint data obtained through public records requests, show that people living in the area encounter the smells at dinner time; on their way to school; at work; on the playground; and during class.

Sometimes the stench comes and goes. But sometimes it persists for hours, or even several days. When it’s especially pungent, it can be stomach-churning. Community members also report getting headaches, as well as an itchy, burning sensation in their eyes and throats.

Quote card reads: An overpowering rotting sweet smell. I can almost taste it. Has triggered my gag reflex multiple times. It has been hanging in the air for over 24 hours now. I have to close all my windows during a heat wave to avoid the horrible putrid smell. It is bad.

In interviews with LAist, affected residents often used phrases like “dead animal” or “rotting carcass” to describe these odors. Still, most of them have no idea where the stench comes from. Some local residents who’ve driven in Vernon past the now-shuttered Farmer John slaughterhouse, which is renowned for its pig murals, told LAist they’d always assumed the smell was coming from there.

“It wasn't just that there was a smell — we all live in cities [that] have smells — it's that it was a stench,” said Jackie Goldberg, Los Angeles Unified School District's school board president. She fielded complaints from teachers and parents at schools near Baker and joined other elected officials in a letter demanding that rendering plants take greater accountability for odors in January 2022.

The smell was so bad it made it impossible to get through the day’s lessons, she said. Students were putting their heads down, asking to go home.

“It impacts your body,” she added. “You feel it in your eyes, you feel it in your throat, you smell it, you get headaches, your eyes burn. It's not good for you, and it’s not good for kids in particular.”

In the months leading up to AQMD’s shutdown action, former state Assemblymember Cristina Garcia wrote her own letter to the agency, detailing her experience teaching math at Huntington Park High School in the ‘90s and early 2000s.

“The smell is so strong, putrid, and nauseating that my students could not focus,” she wrote. “[A]nd now, 20 years later, it is insulting that we are still dealing with the same problem.”

Without working air conditioning in her classroom, Garcia had to choose between shutting the door and windows to keep the odors out, or letting the stench in to get some ventilation. “And the hotter it got, the worse that smell would get,” she told LAist. “It was a constant struggle.”

Baker's lawsuit was news to Garcia when she found out about it from LAist, but not a surprise. She said communities in Southeast L.A. have long been plagued by environmental justice issues and recalled that the now-shuttered Exide battery recycling plant spewed lead in the area for decades, then had its bankruptcy case settled in federal court.

“[Baker feels] that they could win and they could squeeze the agency on behalf of their bottom line, instead of on behalf of the public,” she said.

Dora Gómez and her two children have lived in the city of Vernon for eight years in an affordable housing complex built on land donated by the city. Gómez said the smells have been a persistent issue. When they occur, she shuts her windows and avoids going outdoors. She also bought an air purifier and has routinely purchased scented wax melts to ward off the stench.

Gómez had no idea four rendering plants circle her home in a 4-mile radius. She said she often thinks about leaving the area, but she pays less than $1,500 per month for a two-bedroom apartment and the rents in surrounding neighborhoods are not within her budget.

“It's not a great place to raise your kids,” said Gómez, who said she worries about health effects from Exide in addition to the smell problems. Her apartment building has been flagged by the state Department of Toxic Substances Control for soil remediation after contamination from the battery recycling plant. “They've already been exposed to lead for all these years, it just makes you think like, you know, what else is in the air?

Maria Monares has lived in East Los Angeles, about 3 miles north of Baker’s pressers and grinders, for over three decades. Her children, who are now grown, attended Eastman Avenue Elementary School, just across the street from their home. Monares’ neighborhood has also been subject to rendering plant odors, a “horrible smell” that she compares to the stench of “death” and “burning bones.”

Aside from being unpleasant, the odors can be embarrassing, she said. Sometimes, the stench rolls in when she has company. Visitors will scrunch their faces in disgust and ask: ‘What is that?’

Over the years, Monares and her husband have lodged multiple complaints to AQMD. In some cases, the agency has sent inspectors out to her home. They’ve come, smelled what she’s smelling, asked questions, and taken notes. Then, the air quality got better. And when the odors returned, she and her husband got back on the phone.

“Us calling and bugging, hopefully it helps,” she said.

Businesses near Baker have also filed odor complaints with AQMD. Public records reviewed by LAist show that one company described a “horrible, putrid smell” that they said was coming from Baker. The “smell penetrates into our facility and many employees complain ... Some feel nauseous,” it added.

But pinpointing an odor’s source can be difficult.

“The biggest challenge is that all of [the rendering companies] are located in close proximity to each other,” said Mann, with AQMD. “That's part of the reason why our agency took the lead and created [the odor mitigation rule implemented in 2017],” he said, explaining that the agency now aims to proactively identify violations at rendering companies instead of waiting for complaints to come in before it takes action.

Nastri, AQMD’s executive officer, noted that, in recent years, there’s been an overall drop in odor complaints associated with rendering plants in the region. In 2021, he said, AQMD received nearly 400 complaints. As of Oct. 2, the agency reported 84 complaints so far this year.

Still, he added, “success would be the ultimate elimination of those complaints.”

Rendering’s role in mitigating climate change

Agriculture industry experts agree that rendering plays an important role in reducing waste. Humans don’t eat every part of the animals they consume, so “a tremendous volume of unused animal meat gets left over from our livestock and our poultry operations,” said Christine Birdsong, undersecretary at the California Department of Food and Agriculture.

By repurposing animal remains — like using fats for biodiesel, instead of extracting carbon from fossil fuels — renderers across the country “reclaim the carbon” from 56 billion pounds of unused animal parts each year, Birdsong added. Renderers also minimize waste by transforming those remains into a myriad of “really valuable ingredients” used in everything down to the gelatin casings of medicine capsules, she said.

“I have never seen any other industry that is more involved in recycling,” said Frank Mitloehner, a professor and air quality specialist at UC Davis’ animal science department. “I mean, literally, nothing goes to waste.”

Mitloehner said rendering plants are especially significant when livestock farms experience mass die-offs, often due to the spread of disease or extreme heat. “You’re not allowed to compost [animals], you're not allowed to burn them. There's no other way of dealing with that,” he said.

“Thank God we have people to work in [rendering plants],” Mitloehner added. “Because if we didn’t, we would have a serious disposal issue.”

Some community members frustrated with rendering odors don’t dispute the importance of the recycling work that’s done at Baker.

Dilia Ortega grew up in Huntington Park and now lives in South Gate. She works as a youth program coordinator for Communities for A Better Environment, a nonprofit that’s advocated for clean air, soil, and water in California’s working-class neighborhoods since the late 1970s.

Ortega grew up smelling rendering odors. On her way to school, she’d instinctively cover her mouth and nose when her bus drove past Vernon. Today, her role at work puts her in contact with hundreds of students in Southeast L.A. Year after year, she told LAist, they identify dead animal smells as an ongoing issue in their neighborhoods.

A person with medium-tone skin stands in front of a building where the removed EXIDE name is still visible.

When AQMD was weighing whether to shut down Baker last fall, Ortega shared these insights during public comment at the three-day hearing. She underscored that she was not advocating for a permanent closure. She just wants the company to abide by the rules.

“We understand that they provide a necessary service,” she said. “But it cannot be done at the expense of our quality of life.”

Risks to public health

Jill Johnston, associate professor of Population and Public Health Sciences at USC, noted that strong odors don’t just diminish local residents’ quality of life, they can also impact their health.

Rendering plant emissions can contain chemicals like hydrogen sulfide, which smells like rotten egg, as well as chemicals that contain sulfur dioxide, she said. Some of the symptoms community members have reported — including itchy eyes and runny nose — can be caused by these chemicals. Rendering plant emissions can also exacerbate asthma symptoms, making it harder for residents to breathe, and elevate their blood pressure, Johnston said. Chronic exposure to these odor producing chemicals can also affect their cardiovascular systems.

We shared our findings regarding Baker with Johnston, including what we learned through interviews with community members and our review of AQMD’s violation records.

She said they point to “the need for more stringent enforcement of the standards, to ensure that these violations don't persist.”

Johnston said the density of meat-related facilities in the region is also concerning and could pose a “potential cumulative burden” on nearby communities.

“Even if everyone individually is in compliance,” she explained, “when you’re exposed to so many, the health effects can be greatly amplified.”

Eleni Sazakli, a researcher at the University of Patras’ public health laboratory in Greece, specializes in studying the impact of rendering plants on local communities. She noted that odors can disrupt lives and social relationships. Even hanging laundry out to dry becomes an issue, because the wet cloth picks up the smell, she said.

Quote card reads: It smells like something dead, just such a horrible smell. I love in Commerce, but the smell is the same as it is in Vernon... It's a horrible smell. Thank you.

Odorous chemicals produced by rendering plants can also irritate the throat and nose and “produce headaches, nausea, fatigue and sleep disturbances,” Sazakli added. Some even have the potential to cause cancer.

Pointing to the role rendering plays in reducing waste, Sazakli nevertheless maintained that rendering is “an environmentally friendly industry” that should be sustained.

“But we have to follow very strict guidelines in their operation,” she added, and “adopt the best available technologies that we have in our hands.”

What’s next for Baker’s employees

In its suit against AQMD, and on its company website, Baker warns that the shutdown could impact “about 200 people,” including “more than 100 union-represented employees.”

But when Baker asked AQMD’s hearing board for permission to resume its trap grease and wastewater treatment processes in April 2023, the company’s Jason Andreoli said no staff had been cut.

“[W]e haven’t even let go of any of our employees,” he said at the hearing. “These people are family. ”

Bertha Rodríguez, a spokesperson for United Food and Commercial Workers Local 770, confirmed that none of the 32 union members employed by Baker have lost their jobs.

Martin Perez, who works for Teamsters Local 63 and started a petition to reopen Baker, also told LAist that none of its members have been laid off. During the April hearing he said Baker had been good to its employees.

“Not only did they pay their wages, they paid their health and welfare [and] their pension contributions,” he said at the time.

The International Union of Operating Engineers Local 501, which also has union members who work at Baker, did not respond to multiple requests for comment.

LAist posed the question of jobs to Goldberg, Los Angeles Unified’s school board president, and four Southeast L.A. officials who all complained to AQMD about rendering odors. All agreed that jobs are important. All maintained that the plants need to be in compliance.

“We did not want [Baker] to close, because it employed many of the people that I represent,” Goldberg said, referring to her role on the school board. “But we did want them to run their business following the regulations that they're required to.”

“I would love to see it reopen,” she added, “but I don't want it to reopen if they're not going to be closely monitored and closely regulated.”

Rendering companies “need to adhere to the established regulations,” said South Gate mayor Maria del Pilar Avalos, who lives about 6 miles from Baker. When the rendering odors have been especially pungent, they’ve made her eyes burn. They’ve also caused her family members to forgo day-to-day activities, like walking their dog, she said.

Still, Avalos believes the rendering companies and local residents can coexist. “We need to see how we can utilize our 21st century technology to address those quality of life issues, so that it's a win-win for the companies as well as for our communities,” she said.

In Vernon, plans for a moratorium on rendering plants go nowhere

In response to community concerns, Vernon’s website says the city is considering steps to strengthen local control over rendering. These include plans to enact a moratorium on building new rendering plants, along with increased fines for facilities that are not in compliance with AQMD’s odor mitigation rule.

But Angela Kimmey, deputy city administrator, said the city won’t be enacting the moratorium. The other plans are in “various stages of development,” she said. Vernon aims to encourage business growth and demonstrate that rendering plants and local residents can coexist. To this end, Vernon hosted a tour of a rendering company that’s in compliance with AQMD last summer, inviting regional and southeast L.A. elected officials to come along.

Vernon is also focused on helping facilities come into compliance, Kimmey said.

Vernon Mayor Crystal Larios added in an emailed statement that the city wants “to support our business community,” but recognizes that it has to do its part to shift toward supporting greener commerce, like data centers, green hydrogen, and the electrification of transportation.

A building has pink stucco and a flagstone ledge and door arch. The word Vernon is visible over the glass doors.

“These types of green commerce will not only help existing businesses sustain future growth but heavily reduce the impact on air quality, minimize the number of trucks, and overall decrease the carbon footprint,” Larios said.

LAist requested an interview with Larios multiple times over a four-week period but received no response. Kimmey, who relayed the emailed statement, said the mayor was unavailable.

Hahn, the L.A. County supervisor whose district includes Vernon, told us she was disappointed to see that Baker hasn’t used available state funding to build enclosures that would contain the smells and protect community members from exposure.

Baker “doesn’t seem to think the rules should apply to them,” she said.

“We need the South Coast AQMD to be strong and hold companies accountable,” Hahn added. “I think it is important for residents in Southeast L.A. to know that, unfortunately, this fight isn’t over.”

OC pesticide use

Use in flood control channels causes backlash

Topline:

The Orange County Board of Supervisors has directed its public works department to look into alternatives to using chemicals and pesticides to control overgrowth in flood control channels.

Why this matters: The chemicals clear overgrowth of vegetation, which helps prevent channels from backing up during storms. But critics say it poisons waterways and washes out into the ocean. Supervisor Katrina Foley said she wants to find a better way: “I remain encouraged by the overwhelming public support in exploring nontoxic solutions for our waterways."

What's next: The board will revisit the issue — and the public works department's findings — at a later meeting.

Biking on river trails, going on picnics and surfing in the ocean are activities California residents cherish every summer. But headlines about the use of toxic chemicals in flood control channels around Orange County have created anxiety for those looking forward to their favorite activities this summer.

Dozens of environmental activists and Orange County residents packed the Orange County Board of Supervisors meeting this week to urge the county to halt the routine use of toxins they say poison waterways and wash out into the ocean.

But several supervisors said it wasn’t that simple. The chemical prevents overgrowth in flood control channels, and that overgrowth could lead to backups and flooding, affecting neighborhoods and businesses during heavy rains.

Controversy over the chemical use led to an announcement last month by Orange County Supervisor Katrina Foley, declaring that chemical usage would be halted for the moment. The issue then came before the board this week for further discussion.

Supervisors decided to study the issue and revisit it in the months ahead, and directed the OC Public Works department to evaluate methods for clearing overgrowth of vegetation that crowd flood channels, and look for alternate methods of doing so.

Brent Linas, founder of the Orange County Creek Team, which has succeeded in bringing the environmental issue to the public’s attention through salty Instagram posts and other social media tactics, blasted what he described as the board’s inaction.

He feels that the board is “deeply dysfunctional” and plans on using the meeting as momentum to spread awareness about the chemicals' negative effects on the environment. “There’s palpable outrage in Orange County right now around this and we fully intend to tap into that,” Linas said.

Foley also plans to reintroduce public noticing requirements at the next meeting June 23. The notices would alert residents to the planned use of any pesticides and herbicides. “Orange County residents deserve transparency to help make informed decisions about where their families recreate,” Foley said in a statement released the after the meeting. “I remain encouraged by the overwhelming public support in exploring nontoxic solutions for our waterways.”

How to watchdog your local government

One of the best things you can do to hold officials accountable is pay attention. Your city council, board of supervisors, school board and more all hold public meetings that anybody can attend. These are times you can talk to your elected officials directly and hear about the policies they’re voting on that affect your community.

An opportunity to create an ‘engaging class’

California’s model ethnic studies curriculum describes the field as an “interdisciplinary study of race, ethnicity, and Indigeneity, with an emphasis on the experiences of people of color in the United States.” Districts could develop their course based on this framework or from scratch.

“It was our opportunity to create a really engaging class that really speaks to our student body,” said Luis Haro, Duarte High’s principal for the last eight years.

The majority of Duarte High School’s population is Latino, but there are also Filipino, Asian, white, Black and multiracial students. Most students qualify for free-and reduced price lunches, a proxy for being low-income in public schools.

“In my experience, our students don't know our history, and they don't really have a true understanding of their own identity,” Haro said.

Haro joined a committee of administrators and teachers, including Ramirez, that collaborated with the UCLA History-Geography Project to develop the new course.

UCLA staff guided Duarte educators through reams of local history research and helped the team develop goals for the class, including a student-led civics project.

“Getting to learn and feel like a college student again,” Ramirez said. “It really did make me excited to teach the class.”

They also developed units on students’ personal identity, Indigenous, Latino, Black and Asian American Pacific Islander history. The committee also met with parents and presented their work to the district’s board.

“[Ethnic studies] gave us a path to this project to see people in our community that aren't really talked about,” Ramirez said.

Uncovering the history of the ‘Davis Addition’

The region is the original home of the Gabrielino/Tongva Nation. The then-governor of Alta California granted former soldier Andres Avelino Duarte nearly 7,000 acres in 1841, including what became the city that shared his name. The area was eventually subdivided into farms and eventually, homes.

From the late 19th century through the 1970s, Black and Mexican American families settled in the “Davis Addition,” a subdivision of the land grant that became better known as Rocktown.

Ramirez first read about Rocktown in the research UCLA gathered for the curriculum development process, but couldn’t find much else about the community online.

She started downloading news articles from Newspapers.com and sharing them with the class. Many of the stories often focused on crime and violence in the community, from police raids on drinking and gambling establishments, to fires.

The articles also alluded to the segregation of the early 20th century.

A 1928 article from the Monrovia Daily News described the schedule for a new municipal pool. Mondays were “reserved for the use of colored people.”

“ Why are we not allowing people to do things simply because of the color of their skin or like their origin?” said Khloe Carter, a rising sophomore who took the ethnic studies class.

Carter said it felt important to her, as a person of color, to learn about people’s experiences with discrimination in the past.

“I'd say that has made me smarter and more aware of other people's struggles and what other people have to deal with and other people's cultures and other people's traditions,” Carter said.

A brief history of Rocktown

These events, researched by Ramirez and the ethnic studies class, give an insight into Rocktown.

1841: Mexican government grants nearly 7,000 acres of land to soldier Andrés Avelino Duarte.
1870s-1890s: The rancho is subdivided and sold.
1924: A Monrovia Daily News article describes Rocktown as a “scattered settlement of Mexican and negro homes.”
1957: City of Duarte incorporated.
1960s: Construction of the 210 and 605 freeways.
1970s: Duarte City Council discusses redeveloping Rocktown into an industrial park .
1976: First resident relocated to make way for business center development.

The first wave of Rocktown displacement preceded the construction of the 210 and 605 freeways in the 1960s. The last several dozen families were moved to make way for a business complex in the 1970s. Stories referred to the area as blighted and “depressed.”

“ We took it as our job to dig further, deeper, to find out if it was true or not,” Martinez said.

With Ramirez’s help — and several volunteers from the Facebook group Rocktown Oldies Club — the students started to schedule interviews with former residents. The school’s film class volunteered to record the conversations.

The students heard stories about everyday life that were absent from the news coverage of time — Sunday barbecues, roller skating, fishing, picnicking and swimming near the Santa Fe Dam.

Zamora, who was born in Rocktown in 1949, offered a first-person history that isn’t available elsewhere — down to the community’s name: “ You could not even dig a, a foot into the ground without running into rocks,” he said. “ You could throw water on the ground and a rock would grow, you know?”

Many of the residents raised goats, pigs, pigeons and chickens in their backyards. Zamora said a routine car repair could quickly become a community gathering with neighbors joining in to help.

“That made it … so great to live there, 'cause everybody was like family,” Zamora said. “Even people that weren't related to you, it was really close friendships there.”

Zamora said Rocktown offered a reprieve from the discrimination against Black and Latino residents in other parts of the San Gabriel Valley at the time.

“We played ball together. We swam together. We ate together,” Zamora said. “Even though there was different cultures there, we still were able to get along with everybody.”

These interviews gave the students new perspectives to consider.

“ People make a lot of stereotypes and a lot of guesses … like, ‘Oh, this community can be so ghetto,’" Martinez said. “But honestly, like I think if you haven't been in the community, you can't really say anything.”

Remembering Rocktown

The Duarte Historical Museum hosted a pop-up exhibition of the students’ capstone project.

“I was very impressed with the job that they did, being able to get all this history and the information and the interviews with people,” said Liz Reilly, president of the Duarte Historical Society and Museum and former mayor. "I thought that was really fabulous.”

Reilly, who moved to Duarte in 1987, had heard of Rocktown, but knew little about the neighborhood.

Black and white newspaper clippings attached to a poster board. The headlines include "Five arrested in Rocktown raid," "Rocktown will be erased," and "Gambling raid in Rocktown nets seven."

The exhibition included a map of Rocktown (still the subject of some debate) and dozens of historical photos, often provided by the people they interviewed.

“ I found it so amazing how much people showed up for our project and how much the community of Rocktown has shown up for our project,” Carter said.

Former residents, including Zamora, were among the dozens of people who attended the exhibition’s grand opening in mid-May.

“For them to recognize places that were forgotten, that meant a lot,” Zamora said. “ Nobody seems to remember it. I mean, except the people that lived there.”

Ethnic studies faces growing challenges

While the school’s principal, students and former Rocktown residents have embraced the ethnic studies class, Ramirez said she’s also heard criticism.

During Duarte High’s open house, Ramirez said a parent voiced her disagreement with the class and threatened to file a grievance even though her child had yet to enroll at the school.

“ I'm a parent, so I understand, especially if it's something that you're not familiar with and your kids are learning something different from what you learned, it can be scary,” Ramirez said. “My approach is never to impose my viewpoints. It's to provide alternative perspectives.”

Some lawmakers have also criticized school offerings that intersect with race and ethnicity.

In the last five years, 20 states have banned or restricted teaching critical race theory, an academic concept that race is a social construct and that racism is embedded in specific societal structures.

California school districts from Los Alamitos to San Francisco have faced pushback over their ethnic studies curriculum despite passage of the state mandate.

State lawmakers’ decision to withhold money for teacher training and materials has delayed the ethnic studies graduation requirement.

Daniel Diaz, director of the UCLA History-Geography Project, said there was a flood of interest when the ethnic studies mandate was first passed, but now fewer districts are paying for related professional development.

“Which in turn then impacts what happens to our project and … who we're able to support in terms of staffing,” Diaz said.

In June, UCLA laid off one of the educators instrumental in helping Duarte develop its ethnic studies curriculum.

In a statement, John McDonald, director of media relations at the UCLA School of Education and Information Studies, said the History-Geography Project has laid off four staff members total after funded projects ended in the last year.

“UCLA Center X is committed to the work and actively seeking new funding for similar efforts,” McDonald said.

What that means for other districts looking for assistance with ethnic studies programs remains to be seen.

Ramirez said her UCLA collaborator was “phenomenal” and continued to support the project even after the contract with the district formally ended.

“ I don't think that this year and this project would've been what it was without having that support,” Ramirez said.

Blue street signs read "Evergreen" and "Flower." There are trees and mountains in the distance.

The Rocktown Project’s future

Duarte High School will continue the ethnic studies class.

More former residents have already contacted Ramirez hoping to be interviewed by next year’s students. She also plans to publish the students’ work on a website and a future goal is to memorialize Rocktown with a physical marker in Duarte.

“You need to know whose land you're on and who was there,” said Sylvia Gonzales Youngblood, who was born in Duarte in 1967 and grew up visiting the home her maternal grandfather built in Rocktown.

She said when she was a student there wasn’t an opportunity to learn about her family’s Ohlone Mission Indian and Mexican heritage and she was discouraged from speaking Spanish.

“Now as I'm older, I realize just how much history and of ourselves we lose,” Youngblood said.

Carter, the rising sophomore, said after taking ethnic studies, she feels more connected to the city she moved to about a year ago.

“It's important that we know this side of history so a community like Rocktown doesn't get lost again,” Carter said. “Every voice should be heard, including Rocktown's.”
