An official website of the United States government.

Due to a lapse in appropriations, EPA websites will not be regularly updated. In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.

We've made some changes to EPA.gov. If the information you are looking for is not here, you may be able to find it on the EPA Web Archive or the January 19, 2017 Web Snapshot.

Returning EPA to its Core Mission

EPA is returning to its core mission of protecting human health and the environment. We are committed to providing clean and safe air, water, and land for all Americans. We are building on the enormous progress EPA has made since it was established in 1970 – increasing the safety of lakes and rivers, reducing smog, cleaning up contaminated lands, and guaranteeing the safety of chemicals in the marketplace. 

Priorities:

  • Improving approval time of state plans to meet air quality standards
  • Ensuring safety of chemicals in the marketplace
  • Taking faster action on priority contaminated sites

Actions:
