What are the legal requirements when disposing of saltwater produced by oil and gas operations?

The legal requirements for disposing of saltwater produced by oil and gas operations in Washington vary depending on the nature of the operation. Generally, disposing of saltwater must comply with state regulations, such as requirements of the Department of Ecology. In Washington, operators who operate an oil or gas well discharge saltwater produced from the well off-site must obtain a National Pollutant Discharge Elimination System (NPDES) Permit. The permit outlines measures to reduce saltwater discharges and help minimize impacts to the environment, water quality, and aquatic life. Operators must also comply with the rules and regulations of the Clean Water Act, the Safe Drinking Water Act, and any other applicable federal, state, and tribal laws. In addition, operators may need to obtain an Aquatic Resource Protection Permit (ARPP) from the Department of Ecology in order to dispose of saltwater in a freshwater stream, lake, or wetland. The ARPP will typically require the operator to monitor water quality in order to ensure that the saltwater does not lead to adverse environmental impacts. Operators must also comply with local and county regulations for disposing of saltwater. For example, in King County, Washington, operators are required to obtain a NPDES permit and must also comply with local requirements such as the King County Wastewater Treatment Division’s rules and regulations. Finally, operators must ensure that they are properly disposing of saltwater in an approved facility in accordance with all regulations and permitting requirements. Failure to comply with applicable regulations can lead to financial penalties, criminal charges, and other legal consequences.
