The Trump administration moved Thursday to vastly expand offshore drilling from the Atlantic to the Arctic oceans with a plan that would open up federal waters off California for the first time in more than three decades.

The new five-year drilling plan also could open new areas of oil and gas exploration in areas off the East Coast from Florida to Maine, where drilling has been blocked for decades. While some lawmakers in those states support offshore drilling, the plan drew immediate opposition from governors up and down the East Coast, including Republican Govs. Rick Scott of Florida and Larry Hogan of Maryland, who pressed President Donald Trump to withdraw their states from consideration.

Democratic governors on both coasts blasted the plan. New York Gov. Andrew Cuomo called it "another federal assault on our environment" while California Gov. Jerry Brown vowed to block "this reckless, short-sighted action."

Interior Secretary Ryan Zinke announced the plan, saying that responsible development of offshore energy resources would boost jobs and economic security while providing billions of dollars to fund conservation along U.S. coastlines.

The five-year plan would open 90 percent of the nation's offshore reserves to development by private companies, Zinke said, with 47 leases proposed off the nation's coastlines from 2019 to 2024. Nineteen sales would be off Alaska, 12 in the Gulf of Mexico, nine in the Atlantic and seven in the Pacific, including six off California.

"This is a draft program," Zinke told reporters during a conference call. "Nothing is final yet, and our department is continuing to engage the American people to get to our final product."

Industry groups praised the announcement, which would be the most expansive offshore drilling proposal in decades. The proposal follows Trump's executive order in April encouraging more drilling rights in federal waters, part of the administration's strategy to help the U.S. achieve "energy dominance" in the global market.

"To kick off a national discussion, you need a national plan — something that has been lacking the past several years," said Randall Luthi, president of the National Ocean Industries Association. President Barack Obama blocked Atlantic and Pacific drilling under a five-year plan finalized in 2016.

A coalition of more than 60 environmental groups denounced the plan, saying it would impose "severe and unacceptable harm" to America's oceans, coastal economies, public health and marine life.

"These ocean waters are not President Trump's personal playground. They belong to all Americans and the public wants them preserved and protected, not sold off to multinational oil companies," read the coalition's statement, which was signed by leaders of the Sierra Club, Natural Resources Defense Council, League of Conservation Voters and other environmental groups.

The proposal comes less than a week after the Trump administration proposed to rewrite or kill rules on offshore oil and gas drilling imposed after the 2010 rig explosion in the Gulf of Mexico. The accident on BP's Deepwater Horizon rig killed 11 workers and triggered the biggest offshore oil spill in U.S. history.

The Trump administration called the rules an unnecessary burden on industry and said rolling them back will encourage more energy production. Environmentalists said Trump was raising the risk of more deadly oil spills.
