California Governor Jerry Brown signed legislation [materials] Saturday intended to block the Trump administration’s move to allow drilling off the coast of his state.

SB-834, drafted in January, “prohibits … granted public trust lands from entering into any new lease or other conveyance authorizing new construction of oil- and gas-related infrastructure upon tidelands and submerged lands within state waters,” effectively blocking oil and gas companies from accessing offshore space in which to drill.

A press release [text] from the governor’s office noted California’s alliance with Oregon to prevent offshore oil from reaching the states, citing climate change and California’s 20-year history of not leasing natural lands for the purpose of oil and gas drilling.

President Donald Trump signed Executive Order 13795 [JURIST report] in April, rolling back protections put in place by the Obama administration and allowing offshore drilling companies to bid for land on the US Continental Shelf. The order emphasized “financial burdens” to the oil and gas industry and argued that reducing that cost would boost the economy. The order and others have faced legal challenges [JURIST op-ed], but California’s bill marks the first legislative effort against the order.
