Washington's air pollution problem
Washington is facing a significant air pollution problem, with a recent report from the Washington Department of Ecology revealing that residents in 16 overburdened areas of the state experience a higher death rate from air pollution than the state average. The main sources of outdoor air pollution in Washington are motor vehicles and transportation, outdoor burning, and wood smoke. Other contributors include gas and diesel-powered equipment, some industries, and wildfires.
To address this issue, Washington has implemented several measures. The state has set carbon pollution and greenhouse gas emission reduction targets, with a new cap on industrial emissions taking effect in January 2023. This cap-and-invest law imposes an emissions limit on businesses that emit at least 25,000 metric tons of heat-trapping pollution annually, forcing major polluters to pay for their carbon dioxide emissions. Additionally, Washington has expanded its statewide air monitoring network to gather more data and seek input from community members on the placement of additional air monitors.
The six criteria air pollutants highly regulated at the federal level under the National Ambient Air Quality Standards (NAAQS) are ozone, particulate matter, carbon monoxide, lead, sulfur dioxide, and nitrogen dioxide. While carbon monoxide, sulfur dioxide, and lead are no longer pervasive outdoors in Washington, fine particle pollution, including PM2.5, remains a significant concern and is the most impactful criteria pollutant in the region.
To further combat air pollution, Washington is targeting the largest sources of the most harmful pollutants to protect public health. Fine particle pollution, diesel exhaust, and greenhouse gas emissions are among the air pollutants that present the greatest risk to residents' health. The health impacts of these pollutants include heart and lung issues, as well as potential cancer risk.
Washington is also taking action against big polluters, especially those contributing to climate-damaging pollution. Despite state laws mandating emissions reductions, Washington's climate-damaging pollution has increased over the past decade. Oil refineries, in particular, have been pressured to cut pollution, with some companies investing in cleaner equipment and efficiency improvements to reduce their carbon footprint.

The state's response to climate change
Washington state is taking several measures to combat pollution and address climate change. A key focus is on reducing industrial emissions and holding major polluters accountable. A new cap on industrial emissions, which took effect on January 1, 2023, aims to reduce climate-damaging greenhouse gas emissions. The state is also implementing a "cap-and-invest" law, which imposes an emissions cap on businesses that emit significant levels of heat-trapping pollution. This law will force major polluters to pay for every ton of carbon dioxide they emit, with the first auction of pollution allowances scheduled for February 28, 2023.
Washington is also working to improve air quality and water quality. The state targets the largest sources of the most harmful air pollutants, including fine particle pollution, diesel exhaust, and greenhouse gas emissions, to protect public health. To address water pollution, Washington works with partners to identify problems and provides grants and loans to help implement best management practices. The state also sets water quality standards and evaluates data to create a list of water bodies that need cleanup plans.
In addition, Washington is expanding its statewide air monitoring network to gather more data and track progress towards reducing outdoor air pollution and greenhouse gas emissions. A recent report from the Washington Department of Ecology highlights the disproportionate impact of air pollution on vulnerable communities, with higher death rates from air pollution in certain areas. The state is also addressing nonpoint pollution, which is a leading threat to the health of rivers, lakes, and marine waters, by working with landowners and local governments to implement better land and stormwater management practices.
While Washington has made strides in addressing climate change and pollution, challenges remain. Despite state laws and efforts to reduce emissions, Washington's climate-damaging pollution has increased over the past decade. Oil refineries, for example, face difficulties in cutting pollution as quickly as the state mandates, citing the need for more time to develop and implement cleaner technologies. Nonetheless, some companies, such as BP, have made commitments and investments to reduce their carbon emissions and achieve net-zero emissions by 2050 or sooner.

Water quality standards
The Washington State Department of Ecology has a Water Quality Program that aims to ensure that all aquatic life and communities in the watershed experience clean water to refresh and sustain in the changing climate. The department carries out the federal Clean Water Act for the state, setting limits on pollution to ensure that water supports recreation, business activities, aquatic life, and public health.
The department maintains a database of polluted water bodies called the 303d list, which is one of the most extensive assessments produced by any state in the nation. This database is used to identify water bodies that do not meet state standards and need a plan to be cleaned up. The department works with communities and partners to develop water cleanup plans, also called Total Maximum Daily Loads (TMDLs). They also administer a permit system that places limits on how much pollution industries and municipalities can add to any water body, with special restrictions on adding to water that is already polluted.
The department's surface water quality standards have a three-part approach, covering designated uses such as fishing, swimming, drinking water supply, and aquatic life. They set pollution limits in water quality permits based on these standards, and municipalities, industries, and other water dischargers are required to have these permits to operate. The standards also contain policies to protect high-quality waters and specify how to implement the standards.
In addition, the department identifies waters that are an "outstanding resource" and may receive extra protections. Their antidegradation standards follow federal regulation guides to prevent the unnecessary lowering of water quality, especially in more pristine areas with good water quality.
The US Environmental Protection Agency (EPA) also plays a role in establishing water quality standards for Washington. In 2022, the EPA reestablished federal water pollution standards for Washington, finalizing limits for 72 different pollutants in Washington waters. These stricter limits aim to better protect Tribal fish consumers and all Washingtonians, supporting public health, economic development, cultural activities, and subsistence practices.

The impact on vulnerable communities
Washington's most vulnerable communities are being hit the hardest by air pollution, according to a recent report by the Washington State Department of Ecology. The report, which analyzed data from 2016 to 2020, found that people living in 16 "overburdened" communities across the state experienced a range of negative health outcomes and died 2.4 years sooner on average than those in the rest of the state. These communities represent more than 1.2 million people, or about 15.5% of Washington's population.
The report found that older adults in these communities were twice as likely to die from health conditions linked to breathing fine particles (PM2.5) from human-caused sources. Children in these communities also suffered from asthma and reduced lung function. Other health problems included lung and heart disease, premature births, and premature death. The main air pollutants impacting people's health were identified as fine particulate matter, ozone, and diesel emissions.
The Washington State Department of Ecology has been taking steps to address the impact of pollution on vulnerable communities. They have expanded their air monitoring network in the 16 communities and are seeking input from community members about additional air monitors and sensors. They have also started a new $10 million grant program to improve air quality in these communities, working with local governments, air quality agencies, and Tribal governments to establish stricter air quality standards.
The Climate Commitment Act, Washington's cap-and-invest program, is another key initiative aimed at reducing pollution and improving air quality in vulnerable communities. The Act caps carbon pollution and invests money raised from large polluters in various programs across the state. It also ensures that large pollution sources meet an emissions reduction course to net zero by 2050. The Act includes provisions for environmental justice and concrete steps to reduce air pollution that disproportionately impacts vulnerable communities.
Additionally, community groups are using tools like the Washington Environmental Health Disparities Map to advocate for themselves and highlight the multiple issues they need to address to eliminate disparities. This map brings together information on pollution and community vulnerability, allowing users to visualize and compare environmental health risks across census tracts based on factors such as existing pollution levels, socioeconomic factors, and health outcomes.

Strategies to reduce industrial emissions
Washington is implementing a range of strategies to reduce industrial emissions and combat pollution. A key approach is the issuance of permits to industrial facilities that emit significant levels of pollution. These permits are mandated by federal and state clean air laws and are designed to ensure compliance with legal requirements and protect public health and the environment. Washington has also set targets for reducing carbon pollution and greenhouse gas emissions, which are significant contributors to climate change.
One of the critical strategies is the implementation of a "cap-and-invest" law. This law imposes an emissions cap on businesses that emit at least 25,000 metric tons of heat-trapping pollution annually. The state will hold auctions for pollution allowances, forcing major polluters to pay for every ton of carbon dioxide they emit. This approach incentivizes companies to reduce their emissions and invest in cleaner technologies.
Washington is also targeting the largest sources of the most harmful pollutants, including fine particle pollution, diesel exhaust, and greenhouse gas emissions. By focusing on these significant contributors, the state aims to protect public health and mitigate the impacts of climate change. Additionally, Washington is working to improve water quality by setting standards and developing cleanup plans for waterbodies that do not meet the required standards. They provide technical and financial assistance to industries and municipalities to prevent pollution and improve water quality.
To address air pollution, Washington is expanding its statewide air monitoring network to gather more data and seek input from community members. This data-driven approach will help identify areas most affected by air pollution and guide the implementation of effective solutions. The state is also encouraging the use of cleaner equipment and technologies, such as boilers that run on electricity instead of oil, to reduce emissions from industrial facilities.
Furthermore, Washington is committed to reducing pollution from oil refineries, which are among the state's biggest sources of carbon pollution. While challenges exist in cutting pollution within the desired timeframe, companies like BP are investing in their refineries to cut carbon emissions and improve efficiency. These combined efforts demonstrate Washington's comprehensive approach to reducing industrial emissions and creating a cleaner and healthier environment for its residents.
