Permit recipients, rather than implement project-specific mitigation themselves, typically at the site of permitted impacts (on-site mitigation), contribute mitigation fees to natural resource management entities that the Corps has authorized to receive and use fees to implement required compensation. These entities spend fee contributions from multiple permit recipients on consolidated mitigation projects conducted off-site from the areas of the permitted impacts. The emergence of ILF mitigation in the Section 404 program has been driven by 1) Corps district concerns about the ecological failure of on-site mitigation projects, particularly for minor impacts authorized under general permits, and 2) the absence or insufficient supply of mitigation bank credits in many watersheds where permits are issued. 收起
