Illinois Memorandum of Subsurface Underground Carbon Dioxide Storage Lease and Agreement is a legal document that governs the terms and conditions for storing carbon dioxide (CO2) in underground formations in the state of Illinois. This agreement aims to establish a framework for the safe and responsible storage of CO2, contributing to mitigating greenhouse gas emissions and combating climate change. Some relevant keywords associated with this memorandum include: 1. Carbon dioxide storage: This refers to the process of capturing and storing CO2 emissions from industrial sources or power plants underground to prevent its release into the atmosphere. 2. Underground formations: These are natural geological structures, such as depleted oil and gas reservoirs, deep saline aquifers, or basalt formations, which can safely store CO2 for long periods without negatively impacting the environment. 3. Lease and agreement: The memorandum establishes the terms and conditions for leasing the rights to store CO2 in specific underground formations, ensuring that responsibilities and liabilities are clearly defined for all parties involved. 4. Subsurface storage: The process of storing CO2 below the Earth's surface, typically at depths greater than 800 meters (2,600 feet), to ensure its long-term isolation from the atmosphere. 5. Regulatory compliance: The memorandum outlines the regulatory requirements and standards set by the Illinois Environmental Protection Agency (IPA) and other relevant agencies to ensure that CO2 storage activities comply with environmental laws, safety regulations, and monitoring protocols. 6. Liability and indemnification: The agreement addresses potential liabilities and indemnification for the parties involved in CO2 storage operations, including the leaseholder, landowners, and the state of Illinois. Different types of Illinois Memorandum of Subsurface Underground Carbon Dioxide Storage Lease and Agreement may exist based on the specific underground formations being utilized for CO2 storage. For example, agreements could be tailored for storing CO2 in depleted oil and gas reservoirs, deep saline aquifers, or basalt formations. Each type may have unique considerations regarding geology, technical feasibility, and monitoring requirements. Additionally, the memorandum may be adapted or revised over time to incorporate new scientific knowledge, updates in regulations, and improvements in carbon capture and storage technologies.
