The Corps reevaluated the permit's use and determined that the existing requirement for mandatory pre-construction notification (PCN) for all activities remains a sufficient safeguard to ensure that temporary impacts do not result in more than minimal adverse environmental effects.\n\nWhile the regulatory text is unchanged, the supporting decision document was updated to include current environmental baseline data. This update utilizes the most recent national-scale assessments, such as the 2022 National Lakes Assessment and the 2021 National Wetland Condition Assessment, to support the Corps' finding that the cumulative effects of these temporary activities remain minimal nationwide.","33",[9,10,11,12,13,14],"Installation of a cofferdam to dewater a bridge pier work area","Placement of temporary gravel pads for crane access in a wetland","Construction of temporary work trestles for utility line installation","Temporary dewatering of a canal for maintenance repairs","Discharge of temporary fill for construction vehicle access routes","Placement of temporary bypass structures for stream work","2026-03-15","The Corps determined that the reissuance of NWP 33 has 'no effect' on federally-listed endangered or threatened species or their critical habitat. This finding is anchored by General Condition 18, which requires project-specific Section 7 consultation if a temporary activity 'might affect' listed resources; authorization is only granted once this process is complete.\n\nCompliance with Section 106 of the National Historic Preservation Act is ensured through General Condition 20. Because every project under NWP 33 requires a PCN, district engineers are able to review each temporary layout for potential impacts to historic properties. For Essential Fish Habitat (EFH), district engineers can apply regional conditions to ensure that temporary dewatering or access fills do not disrupt sensitive aquatic life cycles.","json",[19,22,25,28,31],{"q":20,"a":21},"Do I need to submit a PCN for temporary access fills under NWP 33?","Yes, a Pre-Construction Notification (PCN) is mandatory for all activities authorized by NWP 33 before you can start work.",{"q":23,"a":24},"Is there a limit on how much temporary fill I can place?","There is no national numeric acreage limit, but the district engineer will determine if the proposed temporary impact is 'minimal' during the PCN review.",{"q":26,"a":27},"Can I use NWP 33 if my main project doesn't have a permit yet?","No, the primary activity must be authorized by the Corps or the U.S. Coast Guard for NWP 33 to be used for the temporary construction/access portion.",{"q":29,"a":30},"What happens if I can't restore the site to original elevations?","Restoration to pre-construction elevations is a required condition.

This permit is unique because it provides the necessary authorization for the temporary 'logistics' of a project, provided the primary activity itself is already authorized by the Corps or the U.S. Coast Guard.\n\nThe scope of this permit includes both Section 10 navigable waters and Section 404 discharges. It is designed to facilitate the practical side of aquatic construction, allowing for the placement of temporary fill for equipment access or the creation of dry work environments, as long as the site is restored to its original condition once the primary work is finished.","Public feedback for NWP 33 generally supported the permit's role in facilitating construction while requiring restoration. Some commenters suggested implementing a specific acreage limit for temporary fills. The Corps declined to set a hard national acreage limit, stating that the mandatory PCN process allows district engineers to evaluate the 'temporary' nature of each project and require individual permits if the scale of the temporary impact is too large.\n\nOther comments focused on the restoration requirements. The Corps responded by emphasizing that the permit explicitly requires that temporary fills be removed in their entirety and the affected areas be returned to pre-construction elevations. This restoration is a key component of the 'minimal impact' determination for this nationwide permit.","Compliance managers, general contractors, and civil engineers overseeing aquatic infrastructure projects need this permit.
