WASHINGTON (AP) — All solar and wind energy projects on federal lands and waters must be personally approved by Interior Secretary Doug Burgum under a new order that authorizes him to conduct “elevated review” of activities ranging from leases to rights of way, construction and operational plans, grants and biological opinions.

The directive puts these renewable energy projects under heightened scrutiny at Interior in a move that could slow approvals and construction.

The Trump administration said on Thursday that decisions related to solar and wind energy facilities on federal lands will be reviewed by the office of Interior Secretary Doug Burgum to end what it says has been preferential treatment for the renewable energy sources.
