This finding is maintained by General Condition 18, which requires project-specific ESA Section 7 consultation if an activity 'might affect' listed resources. Because many projects under this permit are designed specifically to aid listed fish, the review process ensures that construction timing avoids sensitive spawning or migration windows.\n\nCompliance with Section 106 of the National Historic Preservation Act is ensured through General Condition 20. If a proposed fish passage project involves modifying an older structure that may be eligible for the National Register of Historic Places, a pre-construction notification is required, and the district engineer must complete the NHPA review process before work can begin. Essential Fish Habitat (EFH) is protected through regional conditions that ensure restoration work does not cause more than minimal adverse effects on sensitive marine or estuarine environments.",[3507,3510,3513,3516,3519],{"q":3508,"a":3509},"Do I need to submit a PCN for a fishway project under NWP 60?","NWP 60 does not have a standalone PCN requirement in its national text, but you must still submit a PCN if the project triggers General Conditions for endangered species (GC 18) or historic properties (GC 20).",{"q":3511,"a":3512},"Can I use NWP 60 to remove a small dam?","No, the removal of low-head dams is specifically authorized under NWP 53.

This permit is designed to facilitate the removal of barriers and the construction of features that allow aquatic species to migrate, spawn, and access necessary habitats throughout a watershed. \n\nThe scope includes the construction and maintenance of conventional or nature-like fishways, the removal of small obstructions like fallen trees or sediment bars, and the modification of existing structures like culverts or tide gates. It is intended to streamline projects that provide a clear environmental benefit by reconnecting fragmented aquatic ecosystems and improving overall river and stream health.","Public feedback for NWP 60 was overwhelmingly positive, with many commenters emphasizing the importance of stream connectivity for biodiversity and climate resilience. Some commenters suggested that the permit should be expanded to include the removal of larger dams. The Corps declined this, stating that the removal of larger dams involves complex engineering and potential downstream risks that are better handled under NWP 53 or the individual permit process.\n\nOther commenters requested clarification on whether a PCN is required for small-scale barrier removals. The Corps responded that while NWP 60 does not have a standalone PCN requirement in its national text, many projects will still trigger a PCN under the General Conditions for endangered species, historic properties, or specific regional requirements. This structure allows for administrative efficiency while maintaining oversight for sensitive resources.","Compliance managers for state and local natural resource agencies, non-profit conservation groups, and municipal engineers use this permit. It is the primary tool for authorizing projects intended to upgrade culverts for fish passage, install fish ladders, or remove small debris jams to restore river flow.",[3499,3500,3501,3502,3503,3504],[3523,3524,3525,1739,1237,3526],[3539,3540,3541,3542,3543],{"q":3508,"a":3509},{"q":3511,"a":3512},{"q":3514,"a":3515},{"q":3517,"a":3518},{"q":3520,"a":3521},[124,125,255,3545],"NWP-53",{"title":3547,"description":3548},"NWP 60: Fish & Aquatic Organism Passage - 2026 Permit Guide","Nationwide Permit 60 (NWP 60) for fishways, fish ladders, and barrier removal.
