The PJD will include available literature including U.S. Geologic Survey topographic maps, National Wetland Inventory Maps and other resources. The PJD will also include a field investigation to map and describe the location and condition of all potential jurisdictional waters of the United States within the Project area. 1.5.2 Prepare an initial assessment of the Project and the potential impacts to any waters of the United States to determine whether the Project may utilize the U.S. Army Corps of Engineers Nationwide Permit Program (specifically Nationwide Permit 12 for the Utility Line Activities) for Clean Water Act Section 404 permitting.
