US President Donald Trump will sign an executive order that seeks to expand offshore oil and gas drilling to areas currently off limits, in his administration's latest move to expand domestic energy production.
The order could lead to a reversal of bans on drilling across swathes of the Atlantic, Pacific and Arctic oceans and the US Gulf of Mexico that former President Barack Obama sought to protect from development.
"It is better to produce energy here than be held hostage by foreign entities," interior secretary Ryan Zinke said on Thursday in a briefing about the executive order, which will be called the America-First Offshore Energy Strategy.
Mr Trump campaigned on a promise to do away with Obama-era environmental protections that he said were hobbling energy development and undermining US national security without providing any tangible benefits. Industry cheered but environmental advocates were enraged.
Mr Zinke said the order will require him to review and replace the Obama administration's most recent five-year oil and gas development plan for the outer continental shelf, which includes federal waters off all US coasts.
The order will also reverse Mr Obama's move to place parts of the Arctic permanently off limits to drilling, and encourage more seismic surveying to determine which areas are likely to hold rich reserves of oil and gas.
In addition, under the order Commerce Secretary Wilbur Ross will review previous presidents' designations of marine national monuments and sanctuaries under the 1906 Antiquities Act over the last 10 years.
Weeks before leaving office, Mr Obama banned new oil and gas drilling in federal waters in the Atlantic and Arctic oceans, protecting 115 million acres (46.5 million hectares) of waters off Alaska and 3.8 million acres in the Atlantic from New England to the Chesapeake Bay.
On Wednesday Mr Trump signed a separate order to examine areas of federally managed land to determine if they were improperly designated as national monuments by former presidents, rendering them off limits to development.
