Cancer Alley

Cancer Alley. It is an industrial corridor located along the Mississippi River between Baton Rouge and New Orleans in southeastern Louisiana. This region is home to a dense concentration of petrochemical plants and refineries, which have been linked to severe environmental pollution and elevated public health risks for the predominantly African American communities residing there. The area's nickname reflects longstanding concerns over high cancer rates and other illnesses associated with industrial emissions.

Geography and location

The corridor stretches approximately 85 miles along the winding course of the Mississippi River through several Louisiana parishes. Key locations within this zone include St. James Parish, St. John the Baptist Parish, and Ascension Parish. The region's geography, characterized by flat terrain and proximity to major waterways like the Gulf of Mexico, facilitated the development of industrial infrastructure and the transport of raw materials. This area is part of the larger Mississippi River Delta and lies within the Acadiana cultural region.

Environmental and health concerns

Numerous facilities operated by companies like Dow, ExxonMobil, and Formosa Plastics release significant quantities of air pollutants, including ethylene oxide, chloroprene, and benzene. Studies by agencies such as the Environmental Protection Agency and research institutions have identified some of the highest cancer risks in the nation here, particularly in census tracts near major plants. Communities report not only elevated cancer rates but also high incidence of asthma, respiratory disease, and other conditions linked to toxic exposure.

Industrial history and development

Industrial expansion accelerated after World War II, leveraging the region's access to the Mississippi River and pipelines carrying petroleum and natural gas from the Gulf Coast. The Louisiana Department of Natural Resources and other state entities historically promoted industrial growth, offering tax incentives. Major projects, such as those by Shell and BASF, established a sprawling network of facilities for producing plastics, fertilizer, and synthetic rubber. This transformed the area from an agricultural economy centered on sugarcane plantations into a global petrochemical hub.

Demographics and environmental justice

Many towns within the corridor, such as Reserve and LaPlace, have majority African American populations with high poverty rates. The United Church of Christ's landmark 1987 report and subsequent research by the Deep South Center for Environmental Justice have documented the disproportionate siting of hazardous facilities in these communities. This pattern has made the region a national focal point for the environmental justice movement, highlighting issues of racial segregation and inequitable enforcement of laws like the Civil Rights Act of 1964.

Regulatory and legal context

Regulatory authority involves the Louisiana Department of Environmental Quality and the federal Environmental Protection Agency. Permitting decisions, such as those for the Formosa Plastics complex in St. James Parish, have sparked major legal challenges under the Clean Air Act and the National Environmental Policy Act. In 2022, the United Nations Human Rights Council cited potential violations of international law. Investigations by the United States Department of Justice have examined whether state permits violate the Civil Rights Act.

Community activism and response

Local groups like the Louisiana Bucket Brigade and RISE St. James have organized sustained resistance, often led by figures such as Sharon Lavigne and Robert Taylor. Tactics include air monitoring using "bucket brigades," litigation, and appeals to bodies like the United Nations. National organizations, including the Sierra Club and the Natural Resources Defense Council, provide support. Activism has delayed or canceled major projects and increased national media scrutiny from outlets like The Washington Post and CNN.
