Article: The person or organization submits a HCP and if approved by the agency (FWS or NMFS), will be issued an Incidental Take Permit (ITP) which allows a certain number of "takes" of the listed species. The permit may be revoked at any time and can allow incidental takes for varying amounts of time. For instance, the San Bruno Habitat Conservation Plan/ Incidental Take Permit is good for 30 years and the Wal-Mart store (in Florida) permit expires after one year. Because the permit is issued by a federal agency to a private party, it is a federal action-which means other federal laws can apply, such as the National Environmental Policy Act or NEPA. A notice of the permit application action is published in the Federal Register and a public comment period of 30 to 90 days begins.
