We monitor thousands of emissions points on a regular basis and file monthly, quarterly, semi-annual and/or annual reports with the Environmental Protection Agency (EPA) and the Colorado Department of Public Health and Environment (CDPHE). These agencies also conduct audits of the refinery and its programs on a regular basis.
We work with the EPA and CDPHE to ensure that our Commerce City Refinery has the proper permits. When there are changes to a regulation, we work with regulators to ensure we quickly meet the requirements. We are also regulated by the Occupational Safety and Health Administration (OSHA) and receive inspections regularly. Learn more about the air and water regulations that apply to the refinery.
