poses a significant threat to public health. EPA believes that it will be more cost-effective to use its remedial authority (which is only available at National Priorities List facilities) than to use its emergency removal authority in responding to the facility. EPA may delete a final NPL site if it determines that no further response is required to protect human health or the environment. Also, sites where a remediation was completed through the Superfund program are typically deleted from the list. As of 2022, 1333 sites are on the list, and 48 sites have been proposed for listing. 443 sites were deleted from the list. The primary cleanup goal is to reduce the risks to human health and human health in the environment through a combination of cleanup, engineered controls like caps and site restrictions such as groundwater use restrictions. A secondary goal is to return the site to productive use as a business, recreation or as a natural ecosystem. Identifying the intended reuse early in the cleanup often results in faster and less expensive cleanups. EPA's Superfund Redevelopment Program provides tools and support for site redevelopment. Public comment process The public has the opportunity to comment on facilities that are proposed to be added to the National Priorities List. EPA publishes notices in the Federal Register listing the proposed facilities. The agency will consider all comments received within 60 days after publication in the Register. The complete set of comments are available to the public one week following the close of the comment period. EPA makes a final listing of decisions after considering all the relevant comments that were received during the comment period. EPA Superfund docket The Superfund docket contains the Hazard Ranking System score sheets for each proposed facility, a documentation record for each facility that details the information used to compute the score, information for any facility affected by particular statutory requirements or EPA listing policies, and a list of documents referenced in the documentation record. Mapping system TOXMAP was a geographic information system (GIS) application from the Division of Specialized Information Services of the United States National Library of Medicine (NLM) that used maps of the United States to help users visually explore data from the EPA Superfund Basic Research Program and the Toxics Release Inventory. The application was deprecated in December of 2019 by the Trump Administration. Detailed list List of Superfund sites References
