The Oklahoma Carbon Dioxide Storage Agreement (CSA) is a legal agreement that regulates the storage and management of carbon dioxide (CO2) in underground geological formations within the state of Oklahoma, United States. It is designed to facilitate the long-term storage of CO2 captured from various industrial processes and power generation facilities in an effort to mitigate greenhouse gas emissions. Under the CSA, entities such as industrial plants, power stations, or carbon capture projects must obtain permits and comply with specific regulations to inject and store captured CO2 in designated geological formations. This agreement aims to promote the development of carbon capture, utilization, and storage (CCS) technologies as part of a comprehensive strategy to address climate change. The CSA covers various aspects of CO2 storage, including monitoring, reporting, and verification of stored volumes to ensure the environmental integrity and safety of underground reservoirs. It also includes provisions for the eventual transfer of ownership, liability, and responsibility after the injection and closure of storage sites to ensure long-term stewardship. The agreement typically sets a framework for cooperation between government agencies, project operators, and other relevant stakeholders to harmonize regulations and streamline the storage process. Different types of Oklahoma Carbon Dioxide Storage Agreements may include: 1. Pilot-Scale Storage Agreement: This type of agreement focuses on testing and demonstration-scale projects, allowing organizations to assess the feasibility and effectiveness of CCS technologies in specific geographical areas or geological formations. 2. Commercial-Scale Storage Agreement: This agreement is applicable to larger-scale projects with substantial CO2 storage capacity. It may involve significant investments and may be granted to entities committed to long-term CO2 storage and emissions reduction goals. 3. Cross-Border Storage Agreement: In cases where the underground storage formation extends beyond the boundaries of Oklahoma, a cross-border storage agreement may be required. Such agreements involve cooperation and coordination with neighboring states to ensure the safe and effective storage of CO2 across jurisdictional boundaries. 4. Enhanced Oil Recovery (FOR) Storage Agreement: In certain instances, CO2 storage is used in enhanced oil recovery operations. This type of agreement involves the injection of CO2 to extract additional oil from mature reservoirs while simultaneously storing the CO2 underground. These different types of agreements cater to the varying scale and goals of carbon capture and storage projects in Oklahoma, ensuring the responsible and efficient management of CO2 storage within the state's geological formations.
