NWP 8Effective 2026-03-15

Oil and Gas Structures on the Outer Continental Shelf

Requirements at a Glance

  • Pre-Construction Notification (PCN) is required for all activities
  • Authorized under Section 10
  • Structures must be located within BOEM-leased areas
  • Must comply with BSEE safety and environmental requirements
  • Authorized only under Section 10 of the Rivers and Harbors Act
  • Pre-Construction Notification (PCN) is mandatory for all authorized activities
  • Does not authorize the discharge of dredged or fill material
  • Must not cause more than minimal adverse effects on navigation

Purpose & Scope

Nationwide Permit 8 authorizes structures such as platforms, buoys, and other devices used for oil and gas exploration, development, and production on the Outer Continental Shelf (OCS). These activities must be situated within areas leased by the Department of the Interior's Bureau of Ocean Energy Management (BOEM) and must comply with the specific safety and environmental standards set by the Bureau of Safety and Environmental Enforcement (BSEE). The scope of this permit is limited to Section 10 of the Rivers and Harbors Act of 1899 as extended by the Outer Continental Shelf Lands Act. It does not authorize the discharge of dredged or fill material into waters of the United States, meaning any related activities like pipeline trenching that involve such discharges would require separate Section 404 authorization.

What Changed in 2026

The 2026 reissuance of NWP 8 did not include any substantive changes to the permit's terms or conditions from the 2021 version. The Corps reevaluated the permit's potential impacts using updated data and institutional knowledge, determining that the existing qualitative and quantitative limits remain sufficient to ensure only minimal individual and cumulative adverse environmental effects. While the regulatory text remains unchanged, the supporting decision document was updated with current environmental baseline information. This includes data from recent national-scale assessments such as the 2022 National Lakes Assessment and the 2021 National Wetland Condition Assessment, ensuring the permit's environmental review is grounded in the most current available science.

Who Needs This Permit?

Compliance managers and project engineers in the offshore energy sector use this permit to authorize the physical placement of drilling platforms and production facilities on the Outer Continental Shelf. It is essential for entities operating under federal offshore leases managed by BOEM.

Common Project Types

  • Installation of offshore oil and gas drilling platforms
  • Placement of production facility structures on the OCS
  • Deployment of exploration buoys in federal waters
  • Installation of subsea manifolds and equipment
  • Modification of existing offshore energy structures
  • Installation of safety and meteorological devices on platforms

Environmental Review

The Corps determined that the reissuance of NWP 8 has 'no effect' on federally-listed endangered or threatened species or their critical habitat because General Condition 18 requires project-specific ESA Section 7 consultation for any activity that 'might affect' these resources. No activity is authorized until the Section 7 consultation process is successfully completed. Compliance with Essential Fish Habitat (EFH) provisions is handled through case-by-case or programmatic consultations as necessary. Similarly, Section 106 of the National Historic Preservation Act (NHPA) is managed via General Condition 20, which requires a Pre-Construction Notification (PCN) for any activity with the potential to affect historic properties on the OCS.
