Refineries: The Dark Side Of Air Pollution

Oil refineries are a major source of air pollution, releasing toxic pollutants such as benzene, particulate matter, nitrogen oxides, carbon monoxide, and sulfur dioxide. These pollutants can cause significant harm to both human health and the environment. Studies have shown that people living near oil refineries have higher rates of cancer and experience symptoms such as irritation of the eyes, throat, and lungs, as well as headaches, nausea, fatigue, and loss of appetite. The pollution from refineries not only affects local communities but also natural landmarks, with refineries being responsible for impaired air quality in national parks. Due to the significant impact of refineries on air pollution, the implementation and enforcement of environmental protocols are crucial to mitigate these negative effects.

Petroleum refining releases various toxic air pollutants, including benzene and nitrogen oxides

The refining sector is the most polluting segment of the oil industry. Petroleum refining releases various toxic air pollutants, including benzene and nitrogen oxides. These pollutants are discharged from different phases of the refining process, and they have significant impacts on air quality and the environment.

Benzene is a toxic chemical that is released during the petroleum refining process. It is a known carcinogen and can cause serious health issues, including leukaemia. High concentrations of benzene have been observed in urban areas near petroleum refining and petrochemical industries. These industries also contribute to the presence of other pollutants such as ethylene dichloride, which is used to prevent the deposition of lead oxide in leaded gasoline blends.

Nitrogen oxides (NOx) are another significant pollutant emitted during petroleum refining. NOx contributes to the formation of ground-level ozone, which is a secondary pollutant that is formed from the reaction between volatile organic compounds (VOCs), oxides of nitrogen, and sunlight. Ozone is a harmful pollutant that can cause respiratory problems, coughing, irritation, reduced lung function, asthma, and lung inflammation. The petrochemical industry is a major source of NOx emissions, and the presence of ground-level ozone is a characteristic of photochemical smog, which is often observed in urban areas with high emission sources.

In addition to benzene and NOx, petroleum refining also releases other toxic air pollutants, including VOCs, particulate matter, and greenhouse gases. These pollutants can be released during various stages of the refining process, such as separation, conversion, treating, combustion, and storage. They can also come from auxiliary sources like cooling towers, boilers, and sulfur recovery units. The impact of these emissions can be worse during the summer when temperatures and ozone production rates are higher, and other factors such as vehicular emissions further contribute to ozone formation.

To mitigate the air pollution caused by petroleum refining, it is crucial to establish and impose environmental protocols. This includes implementing measures such as using low NOx burners, gaseous fuel usage, selective catalytic reduction, and energy integration. By reducing NOx generation and overall emissions, these protocols help protect the environment and human health from the harmful effects of air pollution.

Refinery pollution is heavily concentrated near frontline communities, including tribal reservations

Refinery pollution is a significant issue, with the refining sector being the most polluting segment of the oil industry. Oil refineries emit numerous toxic air pollutants, including cancer-causing benzene, particulate matter, nitrogen oxides, carbon monoxide, and sulfur dioxide. The impact of these pollutants is heavily concentrated in the areas surrounding the refineries, and the people living within a 10-mile radius are at a heightened risk of developing serious health issues.

Frontline communities, such as those in Anacortes, Ferndale, and Tacoma, bear the brunt of refinery pollution. These areas are often in close proximity to multiple refineries, intensifying the pollution exposure for residents. Additionally, the pollution affects the tribal reservations of the Lummi, Swinomish, and Puyallup peoples, who are at a disproportionately higher risk of experiencing the adverse effects of refinery emissions.

The Swinomish Indian Tribal Community reservation, for instance, has been directly impacted by refinery pollution. In 2015, the Shell Refinery at Anacortes released chemicals, including benzene, into the atmosphere due to a violation of shutdown and decontamination procedures. The wind carried these chemicals over the nearby Swinomish reservation, exposing the community to harmful pollution. This incident led to fines for Shell from both the Northwest Clean Air Agency and the US Environmental Protection Agency for violating the Clean Air Act.

The pollution from refineries contributes to existing racial and socioeconomic health disparities. Studies have shown that refinery pollution exacerbates health issues such as asthma, cancers, neurological and cardiovascular damage, and blood disorders. These health problems are more prevalent among Black and Native American populations, highlighting the inequitable burden of refinery pollution on specific racial and ethnic groups.

To address refinery pollution and protect frontline communities and tribal reservations, stringent environmental protocols and regulations are essential. This includes enforcing air quality standards, implementing pollution control measures, and holding refineries accountable for any violations or emissions releases. Additionally, transitioning towards cleaner energy sources and improving energy efficiency can help reduce the demand for oil and subsequently decrease refinery pollution over time.

Fines for pollution violations are often used to upgrade refinery equipment, but they are small compared to industry profits

Petroleum refining is a significant contributor to air pollution, and the environmental impact of this sector necessitates the implementation of strict protocols. While fines for pollution violations are intended to deter misconduct and fund equipment upgrades, they are often insufficient compared to industry profits, leading to continued environmental harm.

The Clean Air Act (CAA), enforced by the Environmental Protection Agency (EPA), regulates air emissions from stationary sources, including refineries. However, a study of civil Clean Air Act violations revealed that in 36% of cases, companies found it profitable to violate the regulations, even after paying fines. This profitability increases with the size of the violation, indicating that almost every large violation is financially advantageous for the firm.

The ineffectiveness of these fines is attributed to their small magnitude relative to the profits generated by non-compliance. As a result, corporations may continue to pursue private gains despite causing broader social harm. For instance, an oil and gas company agreed to pay $2.6 million in fines for air pollution violations at an Ohio refinery. While a significant sum, such penalties may not adequately deter future misconduct.

To address this issue, the EPA has the authority to impose larger penalties, as outlined in official policies. However, increasing fines alone may not be sufficient. The EPA must also effectively utilise its enforcement powers, and environmental protocols must be rigorously imposed and enforced to control air pollution effectively.

Furthermore, it is important to recognise that spending on pollution reduction can have economic benefits. Pollution abatement measures can increase productivity, as seen in Los Angeles-area oil refineries between 1987 and 1992. Additionally, investments in pollution reduction create jobs in various sectors, including engineering, manufacturing, and environmental protection. Therefore, while fines for pollution violations may be insufficient, the economic impact of pollution reduction strategies should also be considered in addressing industry profits and environmental harm.

People living near oil refineries have higher rates of cancer and increased cancer-related deaths

Oil refineries emit various pollutants during the different phases of the petroleum refining process. These pollutants are known to be carcinogenic, and the risk of cancer appears to correlate with proximity to the refineries.

A study conducted by researchers at the University of Texas Medical Branch (UTMB) in Galveston found that living within 30 miles of an oil refinery was associated with an increased risk of all cancer types. The study, which analysed data collected by the U.S. Census and the Texas Cancer Registry between 2001 and 2014, showed that Texans living within 10 miles of a refinery were at a significantly higher risk than those living within 20 or 30 miles. This was especially true for lymphoma and bladder cancer, with those living within 10 miles being more likely to be diagnosed with metastatic disease.

Another population-based analysis examined the association between proximity to an oil refinery and cancer rates using multilevel zero-inflated Poisson regression models. This study also found that people residing within 0-10 and 11-20 miles of an oil refinery were significantly more likely to be diagnosed with lymphoma compared to those living 21-30 miles away. Additionally, the study observed an increased risk of regional and distant/metastatic disease according to proximity to an oil refinery.

The International Agency for Research on Cancer has identified important sources of emissions from the petrochemical industries as environmental carcinogens. These emissions include pollutants such as xylene, benzene, toluene, and ethylbenzene compounds, which are known to be carcinogenic. Several Texas refineries have been found to emit benzene at levels above the federal threshold, posing a danger to public health.

Given the evidence, it is clear that people living near oil refineries are exposed to higher rates of cancer-causing pollutants, resulting in increased cancer diagnoses and cancer-related deaths. It is crucial to enforce existing federal laws and establish environmental protocols to protect the health and well-being of individuals living in proximity to these industrial sites.

Refinery growth leads to increased NOx emissions, which can cause more acid deposition and harm ecosystems

The refining sector is responsible for the highest levels of pollution in the oil industry. As refineries grow, so do their emissions of nitrogen oxides (NOx) and sulfur dioxide (SO2), which are key contributors to acid rain. When these gases are emitted into the atmosphere, they react with water, oxygen, and other chemicals, forming sulfuric and nitric acids, which then mix with water and other materials before falling to the ground as acid deposition.

Acid deposition, both wet and dry, can have detrimental effects on soil, forests, streams, and lakes. When acidic rainwater flows through the soil, it can leach aluminum from clay particles, causing an increase in the aluminum content of streams and lakes. While some plants and animals can tolerate moderate amounts of aluminum and acidic waters, others are acid-sensitive and will perish as the pH declines. This can have a ripple effect on the rest of the ecosystem, as everything within it is interconnected.

Acid deposition has been linked to declining fish and shellfish populations in coastal waters. Acid rain and dry acidic particles can also damage statues, buildings, and other structures, corroding metal and causing paint and stone to deteriorate prematurely. Furthermore, NOx emissions contribute to ground-level ozone, which is harmful to human health. Scientific studies have found a correlation between NOx particles and adverse effects on heart and lung function, including an increased risk of heart attacks in individuals with pre-existing heart disease and breathing difficulties for people with asthma.

To mitigate the environmental and public health impacts of increased NOx emissions from refinery growth, it is crucial to establish and enforce stringent environmental protocols. This includes implementing effective emission controls and regularly monitoring air quality to ensure compliance with established standards. By proactively addressing these issues, we can work towards protecting ecosystems, preserving biodiversity, and safeguarding human health from the detrimental effects of acid deposition and air pollution.
