The Environmental Protection Agency’s Approval of Colorado’s Plans to Tackle Ozone Pollution Challenged in Court
The Environmental Protection Agency’s approval of Colorado’s plans to tackle ozone pollution is again being challenged in court by environmental groups, who say state and federal officials are failing to sufficiently scrutinize oil-and-gas-related emissions at the core of the problem.
Introduction
The Center for Biological Diversity and 350 Colorado have filed a lawsuit against the EPA in the 10th Circuit Court of Appeals in Denver. They are challenging the agency’s decision to approve a set of pollution-control regulations submitted by Colorado officials in 2021.
Background
Under the Clean Air Act, Colorado is required to develop a “state implementation plan” to address ozone pollution in a nine-county region in and around Denver. This region has struggled to meet EPA health standards for ozone, a hazardous air pollutant. The EPA designated the area as a “serious” violator of clean air laws in 2019, which mandated stricter rules to achieve compliance by July 2021.
Challenges and Concerns
- The EPA’s approval of Colorado’s 2021 plan comes after the state missed the deadline for compliance, resulting in a downgrade from “serious” to “severe” noncompliance.
- Environmental groups and local governments have urged the EPA to disapprove certain provisions of the state’s plan, particularly those related to emissions modeling and control measures in the oil and gas sector.
- There are concerns that the approved pollution-reduction plan has already failed, allowing the oil and gas industry to continue emitting pollutants that pose health risks.
Current Status and Future Plans
Colorado’s downgrade to “severe” violator status has led to further revisions of the state implementation plan. The Air Quality Control Commission is overseeing this process. In December, the commission approved a plan that acknowledged its failure to meet the EPA’s health standards. Officials have expressed confidence in the iterative process of policymaking under the Clean Air Act and have committed to developing strategies to achieve compliance by 2027.
Ozone Pollution and Sources
Ozone pollution is formed through chemical reactions between sunlight and certain pollutants known as precursors. These precursors include nitrogen oxides and volatile organic compounds, which are emitted by various sources such as oil and gas facilities, motor vehicles, industrial facilities, and lawn and garden equipment. Additionally, “background” ozone transported from other states and even overseas contributes to ozone levels in Colorado.
Sustainable Development Goals (SDGs)
The issue of ozone pollution in Colorado is relevant to several Sustainable Development Goals (SDGs), including:
- SDG 3: Good Health and Well-being – Ozone pollution poses health risks, including asthma attacks and other respiratory problems.
- SDG 7: Affordable and Clean Energy – Transitioning to renewable energy sources can help reduce ozone pollution caused by the oil and gas industry.
- SDG 11: Sustainable Cities and Communities – Achieving clean air in Denver and the Front Range is crucial for creating sustainable and livable cities.
- SDG 13: Climate Action – Ozone pollution is a significant contributor to climate change, and addressing it is essential for mitigating its impact.
Conclusion
Environmental groups are challenging the EPA’s approval of Colorado’s plans to tackle ozone pollution. They argue that insufficient scrutiny of oil-and-gas-related emissions is hindering progress in addressing the problem. Colorado officials are working towards compliance with EPA health standards, but concerns remain about the effectiveness of the approved pollution-reduction plan. The transition to renewable energy sources and the development of comprehensive strategies are seen as crucial steps towards achieving clean air and sustainable development in the region.
SDGs, Targets, and Indicators Analysis:
1. Which SDGs are addressed or connected to the issues highlighted in the article?
- SDG 3: Good Health and Well-being
- SDG 7: Affordable and Clean Energy
- SDG 11: Sustainable Cities and Communities
- SDG 13: Climate Action
- SDG 15: Life on Land
The article discusses the issue of ozone pollution, which is a hazardous air pollutant affecting human health and the environment. It also highlights the role of oil and gas emissions, motor vehicles, industrial facilities, and lawn and garden equipment as major sources of ozone precursor pollutants. These issues are connected to the SDGs mentioned above, which aim to ensure good health, clean energy, sustainable cities, climate action, and the protection of terrestrial ecosystems.
2. What specific targets under those SDGs can be identified based on the article’s content?
- SDG 3.9: By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water, and soil pollution and contamination.
- SDG 7.2: By 2030, increase substantially the share of renewable energy in the global energy mix.
- SDG 11.6: By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management.
- SDG 13.1: Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries.
- SDG 15.1: By 2020, ensure the conservation, restoration, and sustainable use of terrestrial and inland freshwater ecosystems and their services.
Based on the article’s content, the targets mentioned above are relevant to addressing the issues of ozone pollution, reducing emissions from oil and gas facilities, transitioning to renewable energy sources, improving air quality in cities, building resilience to climate-related hazards, and protecting terrestrial ecosystems.
3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?
- Number of deaths and illnesses related to hazardous chemicals and air pollution
- Share of renewable energy in the energy mix
- Air quality index or concentration of ozone precursor pollutants
- Reduction in emissions from oil and gas facilities
- Adaptive capacity and resilience to climate-related hazards
- Conservation and restoration of terrestrial ecosystems
The article does not explicitly mention specific indicators, but it implies the need for monitoring and measuring the number of deaths and illnesses related to air pollution, the share of renewable energy in the energy mix, air quality indicators such as ozone concentrations, emissions from oil and gas facilities, adaptive capacity to climate-related hazards, and conservation efforts for terrestrial ecosystems.
