In summary Five facilities near schools and houses in LA County fumigate produce shipped from overseas with methyl bromide. But the air agency doesn’t plan to monitor the air or take any immediate steps to protect people from the gas, which can damage lungs and cause neurological effects. In a quiet Compton neighborhood near the 710 freeway, children on a recent afternoon chased each other at Kelly Park after school. Parents watched their kids play, unaware of a potential threat to their health.  On the other side of the freeway, just blocks from the park and Kelly Elementary School, a fumigation company uses a highly toxic pesticide to spray fruits and vegetables.  The facility, Global Pest Management, has been emitting methyl bromide, which can cause lung damage and neurological health effects, into the air near the neighborhood for several decades.  Earlier this year, the South Coast Air Quality Management District asked the company — along with four other fumigation facilities in San Pedro and Long Beach — to provide data on their methyl bromide usage. But the air quality agency does not plan to install monitors in the communities that would tell residents exactly what is in their air, or hold community meetings to notify them of potential risks. Instead, the South Coast district has launched a preliminary screening of the five facilities to determine if a full assessment of health risks in the neighborhoods is necessary. But even if that analysis is conducted, the agency won’t require the companies to reduce emissions unless they reach concentrations three times higher than the amounts deemed a health risk under state guidelines, said Scott Epstein, the district’s planning and rules manager. Piedad Delgado, a mother picking up her daughter from the Compton school, said she “didn’t even know” that the hazardous chemical was being used nearby. When a CalMatters reporter told her about the fumigation plant, Delgado wondered if it was causing her daughter’s recent, mysterious bouts of headaches and nausea. “It’s concerning. We may be getting sick but we don’t know why,” she said. For about the past 30 years, the companies have sprayed methyl bromide on imported produce arriving at the ports of Los Angeles and Long Beach to kill harmful pests.

Photo by Joel Angel Juarez for CalMatters Methyl bromide, which was widely used to treat soil on farm fields, has been banned worldwide for most uses since 2005 under a United Nations treaty that protects the Earth’s ozone layer. Exemptions are granted for fumigation of produce shipped from overseas. While little to no residue remains on the food, the gas is vented into the air where it is sprayed. State health officials have classified methyl bromide as a reproductive toxicant, which means it can harm babies exposed in the womb. With acute exposure, high levels can cause headaches, dizziness, nausea and difficulty breathing, while chronic exposure over a year or longer could cause more serious neurological effects, such as learning and memory problems, according to the California Air Resources Board. “It’s concerning. We may be getting sick but we don’t know why.”Piedad Delgado, Compton Resident State and local air quality officials are responsible for enforcing laws and regulations that protect communities from toxic air contaminants such as methyl bromide, while the Los Angeles County Agricultural Commissioner issues the permits to the fumigation companies. After CalMatters reported about the facilities last month, members of Congress representing the communities demanded “greater monitoring, transparency and oversight surrounding these fumigation facilities and their toxic emissions.” “We have serious concerns about the prevalent use of methyl bromide, a toxic pesticide, by container fumigation facilities in Los Angeles County,” U.S. Reps. Nanette Barragán, Maxine Waters and Robert Garcia wrote in an April 11 letter to state and local air regulators and county and federal agricultural officials.  “Several of these fumigation facilities are located close to homes, schools, parks, and other public spaces. Our communities deserve a greater understanding of the levels of toxic emissions from these facilities, the health risks from exposure to such emissions, and the oversight processes in place to ensure all protocols are maintained at these sites,” they wrote. “Our communities deserve a greater understanding of the levels of toxic emissions from these facilities, the health risks from exposure to such emissions, and the oversight processes in place.”U.S. Reps. Nanette Barragán, Maxine Waters and Robert Garcia Even though the San Pedro facility at the Port of Los Angeles and the Compton plant use the largest volumes of methyl bromide — a combined 52,000 pounds a year — the air in nearby communities has never been tested.  The two Long Beach facilities use much less, yet state tests in 2023 and 2024 detected potentially dangerous levels in a neighborhood near an elementary school. South Coast district officials said although certain levels of methyl bromide in the air could cause health effects, it doesn’t necessarily mean immediate action is necessary.  “We don’t want to go out and unnecessarily concern folks if there isn’t (a health concern), but we are actively investigating this right now,” said Sarah Rees, the South Coast district’s deputy executive office for planning, rule development and implementation.   Global Pest Management, which fumigates in Compton and Terminal Island, did not return calls from CalMatters. An employee at the facility declined to comment. A general manager at SPF Terminals in Long Beach also declined to comment.  Greg Augustine, owner of Harbor Fumigation in San Pedro, said his company has been permitted for more than 30 years and complies with all requirements. “To protect the health of our community, the air district establishes permit conditions and we comply with all of those permit conditions,” he said. “Those are vetted by the air district…and they’re all designed to protect the health of our community.”  “To protect the health of our community, the air district establishes permit conditions and we comply with all of those permit conditions.” Greg Augustine, owner of Harbor Fumigation in San Pedro Daniel McCarrel, an attorney representing AG-Fume Services, which fumigates at facilities in Long Beach and San Pedro, did not respond to questions but previously told CalMatters last month that the company is adhering to all of its permit conditions.  High levels found in Long Beach  Back in 2019, during regionwide testing, South Coast district officials detected methyl bromide in the air near the two West Long Beach facilities close to concentrations that could cause long-term health effects. The South Coast district took no action at the time — other than to publish a large study online of all toxic air contaminants throughout the four-county LA basin. Then, several years later, the state Air Resources Board found that the two facilities — SPF Terminals and AG-Fume Services — spewed high concentrations of methyl bromide at various times throughout the year. The state’s air monitor near Hudson Elementary School in West Long Beach — which is just about 1,000 feet from the two facilities — detected an average of 2.1 parts per billion in 2023 through part of 2024. Exposure to as little as 1 ppb for a year or more can cause serious nervous system effects as well as developmental effects on fetuses, according to state health guidelines. Spikes of methyl bromide were as high as 983 and 966 ppb in February and March of 2024. Short-term exposure to 1,000 ppb can cause acute health effects such as nausea, headaches and dizziness.  But state and district air-quality officials didn’t inform nearby residents about any of the monitoring data for longer than a year — not until three months ago, in a community meeting held in Long Beach.  First: Edvin Hernandez, right, waits to pick up his son at Kelly Elementary School in Compton, which is near a fumigation plant. Last: SPF Terminals in Long Beach uses methyl bromide. High levels of the gas were found near an elementary school in West Long Beach. Photos by Joel Angel Juarez and J.W. Hendricks for CalMatters Upon learning of the test results, the Los Angeles County Agricultural Commissioner a few months ago added new permit conditions for SPF Terminals and AG-Fume Services, including shutting doors, installing taller smokestacks and prohibiting fumigation during school hours, according to permits obtained by CalMatters. But the county permits for the three San Pedro and Compton facilities, which use much larger volumes of methyl bromide, remain unchanged, with none of the protections added to the Long Beach permits. And officials still have not held any community meetings there. The agricultural commissioner’s office declined to comment on the facilities. A complex web of ‘hot spots’ rules for methyl bromide About 38% of the methyl bromide used in California for commodity fumigation is in LA County, according to Department of Pesticide Regulation data for 2022. After many Long Beach residents expressed concerns, the South Coast district assessed all nine facilities permitted to use the chemical in the region and determined that five could pose a risk to residents.  Now the agency is going through a complex process outlined under the state’s Air Toxics “Hot Spots” law, enacted in 1987. Usage data, weather patterns and proximity to neighborhoods will be used to calculate a “priority score” for each of the five facilities. If a facility’s score is high enough, then the company will be required to conduct a full health risk assessment to examine the dangers to the community. None of the scores have been released yet. Risk assessments under the air district’s rules are a complicated, multi-step process likely to take many months.

Photo by Joel Angel Juarez for CalMatters And these health assessments may not trigger any changes at the facilities. It all depends on whether certain thresholds for hazards are crossed. The state Office of Environmental Health Hazard Assessment has set guidelines, called reference exposure levels, for concentrations of methyl bromide that could cause the long-term or short-term health effects, such as respiratory and neurological damage, nausea and fetal effects, based on human and animal studies. But South Coast district officials said action isn’t triggered if methyl bromide exceeds these reference levels. Instead, the district uses a state-created “hazard index” based on them. If a facility’s hazard index reaches one — which means concentrations outside the facility have reached the reference dose and could cause harm — the company must notify the public, under a South Coast district regulation. However, the facilities will only be required to take steps to reduce emissions if the hazard index reaches three — three times the reference level that indicates potential harm, according to that regulation. Expedited action is required under the rule if the index is five times higher.   “Just because it’s above the (reference level), it doesn’t mean it’s going to cause health impacts,” said Ian MacMillan, assistant deputy executive officer at the South Coast air district. He said the reference level indicates “there’s a possibility that there could be health impacts.”  The series of escalating thresholds is designed as a balancing act between regulating facilities and protecting the public, officials said. MacMillan also said methyl bromide emissions must be considered in the context of overall air quality in the region — the entire LA basin has an average hazard index of 5.5 when considering all sources of toxic air pollutants from industries and vehicles, he said. When told about the fumigation plants and lack of air testing and risk assessments, residents contacted by CalMatters were outraged. “There’s no interest from the government to protect our health,” said Edvin Hernandez, a father picking up his 9-year-old son from Kelly Elementary School in Compton. “We’re surviving by the hand of God.” The members of Congress — Barragán, Waters and Garcia — asked air regulators to install monitors near all Los Angeles County fumigation facilities, compile inspection records, conduct health assessments in the communities and provide all of the results on a public website.  “It is egregious that communities in California are still being impacted by this harmful and unnecessary chemical,” said Alison Hahm, a staff attorney with the Natural Resources Defense Council, which is working with community members. “In addition to stopping this ongoing public health threat in West Long Beach and Los Angeles, residents are demanding accountability and remedies for the harm endured.” The methyl bromide facilities in L.A. County are subjected to a different permitting process than elsewhere in California.  That’s because in 1996, the South Coast air district and the Los Angeles County Agricultural Commissioner agreed to share responsibility for regulating fumigating facilities. The agricultural office is tasked with issuing permits and the air agency is in charge of setting emissions limits and enforcing them.   In the Bay Area, the local air district has a similar agreement with agricultural departments that originated in 1997. However, the district decided that agreement is out of date so it is now issuing permits, too. One facility in the Bay Area uses the pesticide, Impact Transportation of Oakland. In 2019, the air district assessed the health risks of that facility and modeled how the fumes spread.   In the San Joaquin Valley, new facilities or those changing their methyl bromide use are subject to a health risk evaluation before a permit is issued. Facilities permitted before the air district was established in 1992 are subject to a review like the one that the South Coast district is now launching in San Pedro and Compton. The Los Angeles Agriculture Commissioner’s office, when asked whether it conducts a risk assessment before issuing permits, declined to answer any questions. CalMatters filed a public records request seeking risk assessments, but they said they had no records matching the request.   South Coast air regulators said they and the commissioner are now considering if any changes to their agreement should be made.  Allowed to use up to a half-ton of methyl bromide a day  Fumigation of produce using methyl bromide occurs within an enclosed facility, and the produce is covered by a tarp when sprayed. The fumes are then released into the atmosphere through tall smokestacks, a process called aeration. CalMatters filed a public records request with the county agricultural office and received the five facilities’ permits for 2023 through 2025. The permits show that the two Long Beach companies are now required to take an array of new precautions to limit fumes emitted into communities that the three Compton and San Pedro families are not — even though the Long Beach ones use much smaller volumes of methyl bromide. The San Pedro and Compton plants are allowed to use up to 1,000 pounds of methyl bromide in a 24-hour period. In contrast, the Long Beach plants can use up to 200 pounds in 24 hours, and in Oakland, Impact Transportation’s permit allows only 108 pounds.  First: Pallets of produce are piled up at the outer berths at the Port of Los Angeles in San Pedro.

Photos by Joel Angel Juarez for CalMatters The San Pedro and Compton facilities release fumes into the atmosphere during the daytime, except when they use an exhaust stack meeting certain height requirements, according to their permits. The two Long Beach facilities, SPF Terminals and AG Fume Services, have new, additional requirements this year: Fumigation can’t occur between 8:30 a.m. and 3:30 p.m. when a school is within 1,000 feet. And by the end of this month, they must replace their smokestacks with taller ones that are at least 55 feet tall, which disperse the fumes better. All doors must be closed during fumigation and aeration and fans must be used in the aeration process.  ‘We don’t have a choice’ At a ballpark on a recent day in San Pedro, Eastview Little League players took the field.  When a 13-year-old boy on the Pirates team was up to bat, his mom, Amy Shannon, cheered him on.  “Let’s go D! Deep breath boy, you got it!” she shouted.  Then she paused. Maybe she shouldn’t be encouraging her son to take a deep breath, she said. Shannon had just learned from CalMatters about the fumigation facility across the street from the baseball field. Amy Shannon, left, and Roxanne Gasparo, right, attend their children’s Little League game at Bloch Field near the Port of Los Angeles in San Pedro on April 8, 2025. Both women were unaware that a fumigation facility nearby has been using a toxic gas for about 30 years. Photo by Joel Angel Juarez for CalMatters At the facility where AG Fume and Harbor Fumigation operate, located at 2200 Miner Street, it was business as usual that day. A ship was docked on one side of the Los Angeles Port berth. On the other side, hundreds of stacks of fruits and vegetables were visible through several large garage doors.  Some of the stacks were covered with plastic. A tank containing a fumigant — labeled with a hazard sign depicting a skull — was hooked up outside. Yellow smokestacks protruded from the facility.  An AG-Fume Services truck was parked near one of the garage doors. Workers wearing yellow vests and sun-protective hats closed the garage doors, but left them slightly open at the bottom.  At the baseball field, Shannon watched the game with a friend, Roxanne Gasparo. Both women grew up in San Pedro. Gasparo said she wasn’t at all surprised to learn that a dangerous gas could be in their air.   “Because it’s a port town, unfortunately, we’re used to pollution. We have the port, obviously, and all the refineries next to us,” Gasparo said. “There’s really no way to get out of it unless you leave the city, and because most of the families here are blue collar families that rely on the unions, we kind of don’t have a choice,” she added. “We just deal with it and raise our kids the best we can.” More about air pollution in port communities ‘We should be in crisis mode’: Toxic fumigant could be seeping into these communities March 21, 2025March 26, 2025 Polluted communities hold their breath as companies struggle with California’s diesel truck ban December 10, 2024December 10, 2024
