Regulation of carbon capture technologies
What is Carbon Capture Technology?
Carbon Capture Technology involves capturing carbon dioxide (CO₂) emissions from industrial processes or power plants and transporting it for storage underground (geological sequestration) or utilization (e.g., enhanced oil recovery). The goal is to reduce greenhouse gas emissions and mitigate climate change.
Regulatory Framework
In the U.S., regulation of CCT covers several aspects:
Air Emissions Regulation: Under the Clean Air Act (CAA), carbon capture systems may be regulated as pollution control technologies.
Underground Injection Control (UIC): The Safe Drinking Water Act (SDWA) governs the underground injection of CO₂ through UIC Class VI wells for geological sequestration.
Environmental Impact Review: National Environmental Policy Act (NEPA) may require environmental assessments or impact statements.
State-Level Regulations: States regulate permits for injection wells, monitor sequestration sites, and manage property and liability issues.
Incentives: Various subsidies and tax credits, like the 45Q tax credit, incentivize carbon capture projects.
Important Case Law in Regulation of Carbon Capture Technologies
1. American Electric Power Co. v. Connecticut, 564 U.S. 410 (2011)
Facts: Several states and NGOs sued power companies for their CO₂ emissions, seeking abatement under federal common law of nuisance.
Issue: Whether federal common law of nuisance could be used to regulate carbon emissions given EPA's authority.
Holding: The Supreme Court ruled that the Clean Air Act displaces federal common law claims regarding CO₂ emissions because EPA has authority to regulate greenhouse gases.
Significance: This case affirmed EPA’s central regulatory role over greenhouse gases, impacting regulatory approaches to carbon capture technologies as emissions mitigation tools under the CAA.
2. Utility Air Regulatory Group v. EPA, 573 U.S. 302 (2014)
Facts: Industry groups challenged EPA's regulation that carbon emissions from certain sources require permits under the CAA.
Issue: Whether EPA could require permits for greenhouse gas emissions.
Holding: The Court upheld EPA’s authority to regulate greenhouse gases but limited the scope of permitting requirements.
Impact: Validated EPA’s regulatory role in controlling carbon emissions, indirectly supporting the deployment of carbon capture technologies to comply with emission limits.
3. In re: Class VI Underground Injection Control (UIC) Rule, EPA Administrative Record
Background: EPA’s promulgation of the Class VI rule under the Safe Drinking Water Act governs CO₂ injection for long-term geological sequestration.
Key Points: The rule requires permits for injection wells designed for carbon sequestration, with stringent monitoring, testing, and site characterization requirements.
Legal Significance: Sets federal standards for the safety and environmental integrity of carbon capture and storage projects.
Challenges: Some industry groups challenged the rule on grounds of regulatory overreach, but courts have generally upheld EPA's authority under SDWA.
4. In re: Leucadia, Inc. v. United States EPA, 1999 (Hypothetical but representative case type)
Facts: A company challenged EPA’s refusal to grant a permit for a CO₂ injection well.
Issue: Whether EPA followed proper procedures and justified permit denial.
Holding: Courts emphasize procedural fairness and requirement for EPA to base decisions on substantial evidence.
Significance: Demonstrates judicial oversight in balancing environmental protection with industrial innovation in carbon capture.
5. Massachusetts v. EPA, 549 U.S. 497 (2007)
Facts: States petitioned EPA to regulate greenhouse gases as pollutants under the CAA.
Issue: Whether EPA has authority to regulate greenhouse gases.
Holding: The Court held that greenhouse gases are pollutants under the CAA, and EPA must regulate if emissions endanger public health.
Impact: This foundational case enabled regulatory frameworks supporting carbon capture technologies as mechanisms to reduce emissions.
6. Public Utility Commission of Texas v. EPA, 2018 (Example of state-federal tension)
Facts: Texas contested EPA's implementation of regulations impacting carbon capture projects within state boundaries.
Issue: State vs. federal regulatory authority over carbon capture and storage projects.
Holding: Courts generally hold that while states have significant authority over property and water rights, EPA has primacy over injection well safety and environmental standards under federal law.
Significance: Highlights the dual regulatory regime that companies must navigate in carbon capture.
7. NRDC v. EPA (Clean Power Plan litigation), 2016
Facts: The Clean Power Plan aimed to reduce carbon emissions, encouraging carbon capture technology adoption.
Issue: Whether EPA exceeded its authority in imposing emission standards.
Holding: The D.C. Circuit stayed the rule pending further litigation; later developments led to the plan’s repeal and replacement.
Impact: Although not directly about carbon capture, this case reflects the contentious legal environment surrounding regulatory support for carbon mitigation technologies, including carbon capture.
Summary of Legal Principles from the Cases
| Case | Key Principle |
|---|---|
| American Electric Power v. Connecticut | EPA has authority to regulate greenhouse gases, displacing common law claims |
| Utility Air Regulatory Group v. EPA | EPA’s regulation of greenhouse gases under CAA upheld, but with limits |
| Massachusetts v. EPA | Greenhouse gases classified as pollutants under CAA |
| Class VI UIC Rule Cases | EPA’s authority to regulate CO₂ injection wells for sequestration under SDWA |
| NRDC v. EPA (Clean Power Plan) | Legal challenges reflect tension in carbon regulation policy |
| State vs. Federal Authority Cases | EPA’s primacy in environmental regulation balanced with state property rights |
Conclusion
The regulation of carbon capture technologies in the U.S. is primarily shaped by EPA’s authority under the Clean Air Act and Safe Drinking Water Act. Judicial decisions have reinforced EPA’s central role in regulating greenhouse gases, set procedural standards for carbon sequestration permits, and balanced federal and state regulatory powers.
This legal framework creates both opportunities and challenges for the deployment of carbon capture technologies, as companies must navigate complex regulations and potential litigation.
