How Oil Contributes To Air Pollution

Oil and gas production is a leading cause of air pollution, which has detrimental effects on human health and the environment. Despite a global push for renewable energy, the oil and gas industry continues to expand, causing concern among health experts. Oil spills, refinery processes, and gas leaks release toxic air pollutants, including benzene, formaldehyde, and methane, which have been linked to cancer, asthma, and other adverse health issues. With the sector's growth, the need for comprehensive regulatory action to protect public health and the environment becomes increasingly crucial.

Oil and gas production

The health consequences of exposure to these pollutants are wide-ranging. Short-term symptoms include dizziness, headaches, and respiratory issues, while long-term exposure has been linked to cancer and an increased risk of childhood asthma. The adverse health impacts of air pollution from the oil and gas sector have resulted in thousands of premature deaths, highlighting the urgency of regulatory action to safeguard Americans' health.

To address this issue, it is essential to implement comprehensive strategies that go beyond end-of-pipe pollution controls. Spatial management of emissions in production facilities, leak detection, and control mechanisms are crucial to reducing air pollution and minimizing environmental and health impacts. Continuous monitoring of emissions is necessary, and low-cost air sensors can play a vital role in this process.

As the world transitions towards clean energy, there is increasing pressure on oil and gas companies to decarbonize their operations. The net-zero emissions target set by the Paris Climate Agreement presents a challenge to the energy sector, which must now develop new action plans to reduce greenhouse gas emissions and mitigate their impact on air quality and public health.

Oil spills

The cleanup process after an oil spill is crucial but challenging. Even with advanced technologies like satellite monitoring, cleanup activities can never remove 100% of the spilled oil, and scientists must ensure their methods do not cause further harm. For instance, in the aftermath of the Exxon Valdez oil spill in 1989, it was discovered that high-pressure, hot-water hoses used to clean up beaches caused more damage than the oil alone. As such, sensitive habitats require extra consideration during oil spill cleanup. The Oil Pollution Act of 1990 established that those responsible for oil spills can be held accountable for the cleanup and restoration costs.

To address the issue of oil spills and air pollution, comprehensive regulatory action is necessary to protect communities and the environment from the harmful effects of oil and gas production. This includes improved leak detection and control measures, as well as spatial management of emissions in production facilities. By integrating new technologies and techniques, it is possible to reduce air pollution and minimise environmental impacts.

Oil refineries

One of the main concerns regarding oil refinery emissions is the release of dangerous air pollutants or toxicants. These toxicants, including benzene, formaldehyde, and hydrocarbons, are known or suspected to cause cancer and congenital disabilities. Inhalation of oil droplets and particles during cleanup operations can also irritate the eyes, nose, throat, and lungs, leading to short-term symptoms such as dizziness, headaches, and respiratory issues. Long-term exposure to these toxicants can have even more severe health consequences, including an increased risk of cancer.

Leaky valves and pumps in refineries contribute to fugitive VOC emissions, further degrading air quality. The production, processing, and use of oil and gas result in the emission of significant greenhouse gases, particularly methane. This contributes to climate change and has led to a push for the energy sector to phase out fossil fuels and transition to cleaner energy sources.

To mitigate the environmental and health impacts of oil refineries, leak detection and control are crucial. Continuous monitoring of emissions in production areas is essential, and the use of low-cost air sensors can help detect and reduce emissions. Spatial management of emissions and the implementation of process control systems can also play a vital role in minimizing the negative consequences of oil refinery operations on air quality and human health.

Fugitive VOC emissions

Fugitive emissions are leaks and irregular releases of gases or vapors from pressurized containment. They occur in appliances, storage tanks, pipelines, wells, and other equipment, mostly from industrial activities. These emissions contribute to local air pollution and may cause further environmental harm.

Fugitive emissions include pathways by which ozone-depleting substances and greenhouse gases enter the Earth's atmosphere. The build-up of man-made halogenated gases contributes more than 10% of the radiative forcing that drives global climate change. Fugitive emissions of CFCs and HCFCs from legacy equipment hinder the recovery of the stratospheric ozone layer, despite most production being banned under the Montreal Protocol.

Air pollution standards

Oil spills and the production, processing, and use of oil and gas are major contributors to air pollution. Oil spills release toxic chemicals such as benzene, xylene, toluene, and ethylbenzene, which can cause dizziness, headaches, respiratory symptoms, and cancer. The industry's activities emit methane, a greenhouse gas and key contributor to air pollution, and other harmful pollutants.

To address these concerns, regulatory bodies like the U.S. Environmental Protection Agency (EPA) have implemented various air pollution standards and regulations for the oil and natural gas sector. These standards aim to reduce emissions and protect human health and the environment. Here are some key examples of these standards and regulations:

The Clean Air Act and Amendments

The Clean Air Act, administered by the EPA, is pivotal in combating air pollution from the oil and natural gas industry. It mandates the reduction of harmful air pollutants while enabling responsible growth in the industry. The Act includes federal air standards for hydraulically fractured natural gas wells, addressing previously unregulated pollution sources in the sector. Amendments to the Clean Air Act in 2019 streamlined the permitting process for certain oil and natural gas sources in Indian Country, balancing pollution control with construction authorization.

New Source Performance Standards (NSPS)

The EPA has established the New Source Performance Standards (NSPS) to curb emissions of methane and volatile organic compounds (VOCs) from new, modified, and reconstructed sources in the oil and natural gas industry. These standards are crucial in reducing the industry's emissions of methane, a potent greenhouse gas, and other pollutants that contribute to smog formation.

Emissions Guidelines for Methane

The EPA has issued Emissions Guidelines that provide procedures for states to develop plans to limit methane emissions from existing sources in the oil and natural gas sector. This move addresses the sector's position as the largest industrial source of methane pollution in the U.S.

Paris Climate Agreement

While not specific to the oil and gas sector, the Paris Climate Agreement is an international accord that guides global efforts to reduce greenhouse gas emissions. The energy sector, including oil and gas companies, plays a significant role in achieving the agreement's goals.

Leak Detection and Control

To reduce air pollution and minimize environmental impacts, leak detection and control are essential. Continuous monitoring, aided by low-cost air sensors, is crucial for detecting and reducing emissions in oil and gas production facilities.
