Nitrogen Pollution: Government's Role In Reducing The Menace

Nitrogen pollution is a pressing issue that threatens our environment, health, climate, and ecosystems. It is caused by the use of synthetic fertilizers, the discharge of wastewater, and the combustion of fossil fuels, and has harmful effects on land, water, and air. As nitrogen pollution exacerbates climate change and depletes the ozone layer, it is essential that governments take action to reduce it. The United Nations Environment Programme (UNEP) has recognized nitrogen pollution as one of the most important pollution issues facing humanity, and governments have adopted resolutions calling for sustainable nitrogen management and a significant reduction in nitrogen waste by 2030. In the United States, the Environmental Protection Agency (EPA) works to combat nitrogen pollution in water bodies through various activities, including partnering with stakeholders, providing technical support, overseeing regulatory programs, and conducting research and development.

In addition to providing support and overseeing regulations, the EPA also finances nutrient reduction activities by awarding grants to states for operating nonpoint source management programs. They also work to reduce nitrogen oxide air emissions that contribute to nutrient water pollution through programs like the Clean Air Interstate Rule (CAIR) and by establishing standards for industrial discharges. Furthermore, the agency conducts research and development to study the pathways and effects of nutrient pollution and finds innovative solutions, such as through their National Study of Nutrient Removal and Secondary Technologies. The EPA also plays a crucial role in communicating the latest scientific information, creating public awareness, and encouraging communities to maintain their septic systems through initiatives like SepticSmart Week.

The EPA's efforts to combat nitrogen pollution involve a comprehensive approach that includes collaboration, technical support, regulatory oversight, financing, research, and public communication. These measures aim to reduce the impact of nitrogen pollution on the environment and human health.

The EPA's role in addressing nitrogen pollution is vital, as it protects people and the environment from significant health risks associated with this type of pollution. Their work in this area is ongoing and adaptable to ensure effective nitrogen pollution reduction strategies.

Governments are urged to accelerate actions to support the Global Biodiversity Framework Target 7 by reducing excess nutrients lost to the environment

Nitrogen is an essential element for life on Earth, but excess nitrogen in reactive forms, such as synthetic fertilizers, wastewater discharge, and fossil fuel combustion by-products, poses significant environmental and health hazards. The United Nations Environment Program's (UNEP) 2018-2019 Frontiers Report highlighted nitrogen pollution as one of the most pressing pollution issues facing humanity.

In response to this growing concern, governments are urged to accelerate actions to support the Global Biodiversity Framework Target 7, which aims to "reduce pollution risks and the negative impact of pollution from all sources by 2030 to levels that are not harmful to biodiversity and ecosystem functions and services." This includes reducing excess nutrients lost to the environment by at least half through more efficient nutrient cycling and use.

To achieve this target, governments must take decisive steps to mitigate nitrogen pollution. For instance, the United States Environmental Protection Agency (EPA) is actively combating nitrogen and phosphorus ("nutrient") pollution in US water bodies. The EPA collaborates with various stakeholders, provides technical support to states and tribes, oversees regulatory programs, finances nutrient reduction activities, and conducts research and development. Their initiatives include partnering with the Water Research Foundation to advance nutrient management practices and working with the United States Department of Agriculture (USDA) to encourage state, tribal, and federal efforts to reduce excess nutrients in waterways.

Additionally, the adoption of the Kunming-Montreal Global Biodiversity Framework in December 2022 sets a global biodiversity action agenda for the next decade. This framework includes targets such as ensuring the conservation and restoration of at least 30% of terrestrial, inland water, coastal, and marine ecosystems, reducing the introduction of invasive alien species, and minimizing the impact of climate change and ocean acidification on biodiversity.

By taking comprehensive and collaborative actions, governments can make significant progress in reducing excess nutrients lost to the environment, thereby supporting the Global Biodiversity Framework Target 7 and contributing to the protection of biodiversity and ecosystem health.

The Clean Air Act calls for governments to work together to reduce air pollution

The Clean Air Act, enacted in 1970 and strengthened in 1990, gives the federal government the authority to enforce regulations that limit air pollution. The Act has a proven record of public health and environmental protection, with Americans breathing less pollution and facing lower risks of premature death and other serious health effects.

The Clean Air Act has been instrumental in reducing the country's air pollution over the past few decades, and it also plays a crucial role in the US economy by reducing healthcare costs and absences from work or school. It is a comprehensive federal law that gives the Environmental Protection Agency (EPA) the authority to regulate air pollutants and polluting industries. The Act requires the EPA to set national health-based standards for air pollution and to review, update, and enforce these standards. The federal government sets national ambient air quality standards, but state and tribal governments are responsible for meeting and maintaining those standards.

The Clean Air Act has been successful in reducing air pollution, with particulate matter pollution (the deadliest form) declining by 41% and ozone pollution by 22% since 1990. This has led to a decline in environmentally related respiratory illnesses and improved air quality, benefiting public health and the economy.

However, the Act has faced challenges and pushback from different presidential administrations and industries. Despite these obstacles, the Clean Air Act remains a crucial tool in the fight against air pollution and climate change, with the EPA taking initial steps to limit emissions that contribute to these issues.

The EPA provides technical assistance to communities implementing green infrastructure

The US Environmental Protection Agency (EPA) provides technical assistance to communities implementing green infrastructure. This is part of the EPA's ongoing efforts to combat nitrogen and phosphorus ("nutrient") pollution in US water bodies.

The EPA's Green Infrastructure Program promotes the use of plants, soils, and nature itself to manage stormwater and create healthier urban environments. Green infrastructure practices can reduce the need for "gray infrastructure," such as pipes, storage facilities, and treatment systems. This is because plants, soils, and other media can soak up, store, and use rainwater.

The EPA has worked with over 50 communities to create conceptual green infrastructure designs, review local codes, develop guidance, estimate economic benefits, and model the positive effects of incorporating green infrastructure into the urban landscape.

The EPA provides technical assistance for the nonpoint source sector under Clean Water Act section 319 in areas of nutrient management, such as agricultural management practices, management of onsite disposal systems, and urban/suburban green infrastructure practices.

The EPA also offers funding and technical assistance opportunities to help communities implement green infrastructure. Federal, nonprofit, and local funding resources are available. The Bipartisan Infrastructure Law, for example, provides $50 billion in funding for water infrastructure needs, including green infrastructure.

The EPA's Green Infrastructure Program offers several types of assistance to various partners, including technical, outreach and education, and financial assistance. This assistance helps implement projects to build climate resilience.

The EPA works with the Water Research Foundation to reduce excess nutrients in waterways

The United States Environmental Protection Agency (EPA) is actively working to combat nitrogen and phosphorus pollution ("nutrient" pollution) in US water bodies. One of their key initiatives is their collaboration with the Water Research Foundation (WRF) to reduce excess nutrients in the nation's waterways.

In February 2019, the EPA and WRF signed a Memorandum of Understanding (MOU) to accelerate progress in addressing excess nutrients in US waterways. This MOU builds on the success of the Nutrient Recycling Challenge, a competition launched to develop affordable technologies for recycling nutrients from livestock manure. Through this partnership, the EPA and WRF aim to:

• Facilitate greater collaboration between the regulated water community, technology developers and providers, and agricultural producers.
• Match innovative manure and nutrient management technologies with on-farm testing sites, funders for technology demonstrations, and third-party evaluators.
• Enable producer-to-producer information exchange regarding technology performance.
• Develop and disseminate information on specific topics related to manure management and resource recovery and reuse.

By partnering with WRF, the EPA aims to advance nutrient recovery science and innovation, support on-farm demonstrations and installations, and connect stakeholders across the nutrient value chain to maximize environmental and economic outcomes. This collaboration is a crucial step in tackling nutrient pollution and protecting America's waters.

The EPA is also actively engaged in other initiatives to reduce nitrogen pollution. They are co-leading the Mississippi River/Gulf of Mexico Hypoxia Task Force, working with the United States Department of Agriculture (USDA) to encourage state, tribal, and federal efforts, and providing technical and programmatic support to states, tribes, and territories. These comprehensive efforts demonstrate the EPA's commitment to addressing nutrient pollution and improving water quality.
