NWP 51 — Land-Based Renewable Energy Generation Facilities
NWP 51 was created to authorize discharges of dredged or fill material into non-tidal waters of the United States for the construction, expansion, or modification of land-based renewable energy projects. This permit may be used on projects of up to half an acre on non-tidal wetlands, or projects that will impact no more than 300 linear feet of stream bed. The NWP covers the installation of actual renewable energy structures as well as attendant features, including roads, parking lots, utility lines, and stormwater management facilities. A significant factor for a project applicant who is considering using NWP 51 is that it requires preconstruction notification to, and approval by, ACE prior to the commencement of the project. ACE may exercise discretionary authority to place additional conditions on a proposed activity, or to require an applicant to pursue a regional general permit or an individual permit.
NWP 52 — Water-Based Renewable Energy Generation Pilot Projects
NWP 52 is similar to NWP 51 in that it requires preconstruction notice for any activities, and may be used on projects of up to half an acre of non-tidal wetlands, or that will impact no more than 300 linear feet of stream bed. However, NWP 52 applies only to pilot projects, which is limited to experimental projects where the renewable energy generation units will be monitored to collect information on their performance and environmental effects at the project site.
New NWP General Condition 19 — Migratory Birds and Bald and Golden Eagles
In addition to the new NWPs for renewable energy projects, ACE also added a new NWP General Condition for all NWPs that is specific to migratory birds and bald and golden eagles. Under NWP General Condition 19, ACE clarified that if issuance of an NWP will result in a “take” of a migratory bird or a bald or golden eagle, that it is the applicant’s responsibility to apply for, obtain, and comply with any required take permit.
Impact to Industry
Although the goal of these new NWPs was to simplify the permitting process for the development of renewable energy projects, the requirement under both NWP 51 and NWP 52 for a preconstruction notification to ACE creates a higher burden than for most other NWPs. Under the majority of existing NWPs, including NWP 12 for construction of utility lines and NWP 14 for linear transportation projects, preconstruction notifications are generally only required if more than one-tenth of an acre will be disturbed. Although these new NWPs provide a good option for reducing the permitting requirements for certain elements of renewable energy projects, including the construction of parking lots or stormwater features, it is likely that many renewable energy projects will continue to rely solely upon NWPs 12 or 14 where the impacts to navigable waters from projects are limited to impacts from the construction and installation of utility lines or roads.
