The National Park Service prepares a variety of planning and environmental documents to help guide it in managing park resources. These documents can range from site-specific impact analyses on facility locations to broader park-wide plans for future use and management of a park. The Planning, Environment and Public Comment (PEPC) site contains all of the currently active plans and environmental documents for Katmai as well as other units in the National Park System. Public involvement is welcomed on documents currently open for comment.
