When to Prepare

When to Prepare an EA

An EA will be prepared for all proposed actions except: (1) actions that are categorical exclusions, (2) actions fully analyzed in prior NEPA documents, and (3) actions to be analyzed in an EIS.   Four types of permit and approval actions require the preparation of EAs:

bulletPermit applications for geological and geophysical survey activities that involve:
  1. deep stratigraphic tests, as defined or cited by 30 CFR 251,
  2. solid or liquid explosives, or
  3. prospecting actions described under 30 CFR 280.

bulletExploration Plans (EPs), and/or revisions to approved EPs if the proposed revision could result in a significant change in the impacts previously identified and evaluated or requires additional permits (30 CFR 250.203 and delineation and testing actions under 30 CFR 281).

bulletDevelopment and Production Plans (DPPs), and/or revisions to approved DPPs if the proposed revision could result in a significant change in the impacts previously identified and evaluated, requires additional permits, or proposes activities not previously identified and evaluated (30CFR 250.204, and 30 CFR 282.24).

bulletApplications for pipelines that go to shore that are not part of an approved DPP or Development Operations Coordination Document (DOCD). 

In addition to permitting actions, EAs may be prepared for proposed lease sales, area-wide impact assessment, generic impact assessment, assessment of legislative or regulatory proposals, and for planning purposes.  When appropriate, regions may consider circulating draft EAs to ensure public input.
