Essential Functions

Environmental Statutes and Executive Orders

The Bureau must comply with numerous environmental statutes, regulations, and executive orders to carry out its mission. The links below describe those legal requirements and our environmental policies and procedures that apply to the OCS Energy Program. Where available, links are provided to other websites with the full text of the laws, relevant regulations, and guidance issued by other agencies.


  • International Agreements
  • Analytical Support for Responses to Congress, States, and other parties. The BEA prepares correspondence to elected officials and other parties, and responds to question on environmental issues following Bureau testimony before Congressional committees and during the annual budget appropriations process.
  • Liaison with Other Agencies and Organizations. The BEA professional staff conducts ongoing liaison, consultation, and outreach activities with various other bureaus within DOI, agencies external to DOI, State agencies, the environmental community, industry organizations, and other groups which are directly associated with mineral and energy development. These activities are both routine in order to keep up with activities of these groups and ad hoc as special problems arise.
