The days-long threat of a catastrophic chemical explosion<\/a> in Garden Grove has exposed the pervasive yet often ignored industrial risks hidden amid daily life in Southern California, where aerospace plants and petrochemical facilities are interwoven amid homes, schools and parks. <\/p>\n

Now, experts say this aging infrastructure is converging with population growth and regulatory rollbacks that are increasing the likelihood that similar incidents will happen again.<\/p>\n

The greater Los Angeles area became a global hub for aerospace and defense manufacturing around the start of World War II, with companies here producing military aircraft, electronics, plastics, petroleum products and other specialized materials that helped transform the region into a dense manufacturing zone even as its suburban footprint was expanding.<\/p>\n

Many of those operations used petrochemical products and solvents such as resins, adhesives and acrylic compounds like methyl methacrylate<\/a>, the chemical at the center of the Orange County crisis. While some of that work has slowed since the end of the Cold War, many industrial sites remain active and tucked among communities. <\/p>\n

That makes the possibility of another Garden Grove incident a matter of \u201cif,\u201d not when, said Seth Shonkoff, executive director at the science research institute PSE Healthy Energy<\/a>. <\/p>\n

\u201cIt\u2019s not really whether industrial accidents are possible in the L.A. Basin \u2014 they are,\u201d he said. \u201cThe important question is whether regulatory systems, emergency preparedness and land use decisions are keeping pace with changing industrial hazards and growing urban densities.\u201d <\/p>\n

While the Garden Grove incident was in some ways an outlier driven by specific system failures, there are several factors that make it likely to now occur more often, said Shonkoff, who is also an associate researcher at the UC Berkeley School of Public Health.<\/p>\n

They include global warming, which is increasing the average number of extreme heat days<\/a> in Southern California, putting more strain on storage tanks and industrial processes that rely on the need to keep production materials cool<\/a>.<\/p>\n

At the same time, a lot of the region\u2019s industrial infrastructure is aging, which also heightens their risk of leaks, cracks or failure.<\/p>\n

But perhaps most critical is the push to build more housing in places where housing has not typically been constructed. Sometimes that means more people are moving into undeveloped areas along the wildland-urban interface<\/a>, which can put them at greater risk for wildfires, but other times, it means they are moving closer and closer to industrial zones.<\/p>\n

\u201cWhen you increase the population density around these types of facilities, you are increasing the hazard that if something goes mechanically wrong, more people are going to be at risk,\u201d Shonkoff said.<\/p>\n

Many of these areas are home to low-income communities and communities of color that already experience disproportionate harms from pollution and other environmental hazards, said Deja McCauley, land use and health program manager with the nonprofit Physicians for Social Responsibility Los Angeles.<\/p>\n

This has already been evidenced by previous environmental disasters, such as the decades of lead contaminants that spewed from the Exide battery plant in Vernon<\/a>, or toxic dust and explosions from the Atlas Metals recycling plant in Watts<\/a>.<\/p>\n

Just last week, while emergency crews responded to the chemical crisis at GKN Aerospace facility in Garden Grove, 2,400 gallons of crude spilled<\/a> into the Los Angels River near East Los Angeles, and a fire burned at a tire recycling center<\/a> in South Gate, prompting a shelter-in-place order.<\/p>\n

But while some communities are moving closer to existing industrial facilities, there are also regulatory changes that are making it easier for industrial facilities to be built closer to communities, McCauly said. <\/p>\n

Last year, Gov. Gavin Newsom passed two controversial bills that overhauled the California Environmental Quality Act<\/a>, or CEQA. The legislation exempted a broad array of housing development and infrastructure from environmental review in an effort to streamline construction and help address housing scarcity in California.<\/p>\n

While some hailed it as a necessary cutting of red tape, critics said the move will expose more vulnerable communities to potential harms: The legislation included an exemption for advanced manufacturing facilities<\/a>, such as semiconductor plants, nuclear facilities, industrial factories and other places that handle high-risk hazardous material, to be permitted in some communities without any environmental review. <\/p>\n

At the same time, the Trump administration has taken steps to roll back regulations on emissions from industrial facilities, such as mercury and other toxics emitted from coal plants<\/a>. Earlier this year, the administration said it will loosen limits on emissions of ethylene oxide<\/a>, a cancer-causing chemical<\/a> often used in the sterilization of medical devices, including at multiple facilities in Los Angeles<\/a>.<\/p>\n

\u201cWhat\u2019s happening at Garden Grove \u2014 we\u2019re going to see a lot more of that due to these environmental rollbacks,\u201d McCauly said. <\/p>\n

A new state bill, SB 954<\/a>, is now advancing through the legislature and would restore some of the CEQA protections that were removed last year, including narrowing the types of facilities that can bypass environmental review and providing more guidelines for siting sensitive places such as schools, homes and daycares, among other changes.<\/p>\n

But part of the reason communities here remain vulnerable to incidents like Garden Grove is that many people aren\u2019t aware of the region\u2019s long history of industrial manufacturing, said Peter Westwick, an adjunct history professor at USC and director of the Aerospace History Project<\/a>. <\/p>\n

\u201cIts association with Hollywood, which is what most people probably think of as \u2018the industry\u2019 in L.A., has probably obscured the manufacturing presence, along with L.A.\u2019s suburban image,\u201d Westwick said. <\/p>\n

Even before the manufacturing and aerospace boom, L.A.\u2019s industrialization started with natural resource extraction driven by the oil industry, he said \u2014 a legacy that also continues to pose threats such as the Chevron refinery explosion<\/a> in El Segundo last year. <\/p>\n

From the 1940s to the 1960s, L.A. also had a thriving auto industry that was second only to Detroit, producing half a million cars at its peak.<\/p>\n

\u201cAll this manufacturing provided a lot of jobs and drove L.A.\u2019s remarkable growth in the early and mid 20th century, but it had a major legacy in air pollution, groundwater contamination and so on,\u201d Westwick said. <\/p>\n

He added that \u201cthe current emergency is Garden Grove is just an example of this longer embedding of industry around L.A.\u201d<\/p>\n

For now, much of the responsibility for managing the risk falls to individuals. Tools such as CalEnviroScreen<\/a> or PSE\u2019s methane risk map<\/a> can help people locate pollution sources, toxic facilities and other threats in their area.<\/p>\n

State agencies such as the California Air Resources Board, the California Environmental Protection Agency and the Office of Environmental Health Hazard Assessment also offer various guidelines or enforcement mechanisms, but their jurisdictions are fractured and disjointed, said Shonkoff, of PSE Health Energy. <\/p>\n

He said the biggest factor that will determine when the next Garden Grove happens is not individual actions, but how industry and regulators approach the safety of these facilities, including where they should be sited. <\/p>\n

\u201cThe onus should be put on the facilities to manage their risk,\u201d he said, \u201cand also on regulators to make the important decisions of when \u2018close\u2019 is too close.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"The days-long threat of a catastrophic chemical explosion in Garden Grove has exposed the pervasive yet often ignored…\n","protected":false},"author":2,"featured_media":334747,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[179,138386,21298,1512,138384,138385,21403,8076,35362,48,52,51,7036,47,50,49,63,138387,10263,17135,1009],"class_list":["post-334746","post","type-post","status-publish","format-standard","has-post-thumbnail","category-los-angeles","tag-community","tag-defense-manufacturing","tag-environmental-review","tag-facility","tag-garden-grove-crisis","tag-industrial-risk","tag-industry","tag-infrastructure","tag-l-a-basin","tag-la","tag-la-headlines","tag-la-news","tag-last-year","tag-los-angeles","tag-los-angeles-headlines","tag-los-angeles-news","tag-los-angeles-times","tag-peter-westwick","tag-region","tag-seth-shonkoff","tag-southern-california"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/334746","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=334746"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/334746\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/334747"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=334746"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=334746"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=334746"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
