 state agencies.  Additionally, certain of our other facilities, such as terminals and biodiesel plants, generate lesser quantities of hazardous wastes.

Under RCRA, CERCLA and other federal, state and local environmental laws, as the owner or operator of refineries, biodiesel plants, bulk terminals, pipelines, tank farms, rail cars and trucks, we may be liable for the costs of removal or remediation of contamination at our existing or former locations, whether we knew of, or were responsible for, the presence of such contamination.  We have incurred such liability in the past, and several of our current and former locations are the subject of ongoing remediation projects. The failure to timely report and properly remediate contamination may subject us to liability to third parties and may adversely affect our ability to sell or rent our property or to borrow money using our property as collateral.  Additionally, persons who arrange for the disposal or treatment of hazardous substances also may be liable for the costs of removal or remediation of these substances at sites where they are located, regardless of whether the site is owned or operated by that person. We typically arrange for the treatment or disposal of hazardous substances generated by our refining and other operations. Therefore, we may be liable for removal or remediation costs associated with releases of these substances at third party locations, as well as other related costs, including fines, penalties and damages resulting from injuries to persons, property and natural resources. In the future, we may incur substantial expenditures for investigation or remediation of contamination that has not been discovered at our current or former locations or locations that we may acquire or at third party sites where hazardous substances from these locations have been treated or disposed.

Risks Related to Air Emissions Regulations

Our operations are subject to certain requirements of the CAA, as well as related state and local laws and regulations governing air emissions.  Certain CAA regulatory programs applicable to our refineries, terminals and other operations require capital expenditures for the installation of air pollution control devices, operational procedures to minimize emissions and monitoring and reporting of emissions.  

A consent decree was entered in the U.S. District Court for the Northern District of Texas in June 2019 resolving alleged historical violations of the CAA at our Big Spring refinery. In addition to a civil penalty of $0.5 million that we paid in June 2019, we will be required to expend capital for pollution control equipment that may be significant over the next 3 years. According to the EPA, approximately 95% of the nation's refining capacity has entered
