The DEQ director has the authority to issue fines for violation of pollution laws and standards. The DEQ relies on several advisory committees of citizens and government officials to help guide its decision-making.
DEQ is responsible for protecting and enhancing Oregon's water and air quality, for cleaning up spills and releases of hazardous materials, for managing the proper disposal of hazardous and solid wastes, and for enforcing Oregon's environmental laws.  

History timeline
Success stories
Oregon's history of environmental regulation dates back to 1938 when the Oregon State Sanitary Authority was formed. As a division within the State Board of Health, the Authority was formed in response to outraged citizens who overwhelmingly supported an initiative petition known as the "Water Purification and Prevention of Pollution Bill." The bill declared a state policy to preserve Oregon waters from pollution. In 1969, the Authority changed its name to the Department of Environmental Quality and established itself as an independent state agency.
In 2009, Oregon DEQ celebrated its 40th anniversary, commemorating the event with the publishing of its history timeline and series of success stories representing its various programs.
