SACRAMENTO, Calif. (AP) — For decades, California and the federal government have had a co-parenting agreement when it comes to the state's diverse population of endangered species and the scarce water that keeps them alive.
Now, it appears the sides could be headed for a divorce.
State lawmakers sent to the governor early Saturday morning a bill aimed at stopping the Trump administration from weakening oversight of longstanding federal environmental laws in California. The lawmakers want to make it easier for state regulators to issue emergency regulations when that happens.
"The feds are taking away significant pieces of water protection law, of air protection law, and California has to step into the void," Democratic Assemblyman Mark Stone said.
Democratic Gov. Gavin Newsom has 30 days to decide whether to veto the bill, sign it into law or allow it to become law without his signature.
The bill survived a furious lobbying effort on the Legislature's final day, withstanding opposition from the state's water contractors and Democratic U.S. Sen. Dianne Feinstein.
"We can't really have a California system and a federal system," said Jeffrey Kightlinger, general manager of the Metropolitan Water District of Southern California, which delivers water to nearly 19 million people. "We're all in the same country here, so we need to find a way to make this work."
California has a history of blunting Republican efforts at the federal level to roll back environmental protections. In 2003, shortly after the George W. Bush administration lowered federal Clean Air Act standards, the Legislature passed a law banning California air quality management districts from revising rules and regulations to match.
More recently, after the Trump administration announced plans to roll back auto mileage and emission standards, Newsom used the state's regulatory authority to broker a deal with four major automakers to toughen the standards anyway.
State lawmakers tried this last year, but a similar proposal failed to pass the state Assembly. But advocates say several recent announcements by the Trump administration — including plans to weaken application of the federal Endangered Species Act — have strengthened support for the bill.
The bill would potentially play out most prominently in the management of the state's water, which mostly comes from snowmelt and rain that rushes through a complex system of aqueducts to provide drinking water for nearly 40 million people and irrigation to the state's $20 billion agricultural industry.
The bill would make it easier for state regulators to add animals protected under California's Endangered Species Act — animals that have historically been protected under federal law. It would then apply the state's Endangered Species Act to the Central Valley Project, a federally operated system of aqueducts and reservoirs that control flooding and supply irrigation to farmers.
But it's not clear if a state law would apply to a federal project, "which could generate years of litigation and uncertainty over which environmental standards apply," according to a letter by Feinstein and four members of the state's Democratic congressional delegation.
Plus, Kightlinger warns the proposal would disrupt complex negotiations among state and federal entities and water agencies over the Water Quality Control Plan. If all sides can sign these voluntary agreements, it would avert costly litigation that would delay environmental protections for fish and other species impacted by the water projects.
"We're pretty close. We believe we can get to completion by December. If (this bill) passes, half of the water districts pull out and go to litigation instead," Kightlinger said. "That's something that would be terrible for our ecosystem and what we're trying to achieve here."
Senate President Pro Tempore Toni Atkins, the bill's author, insisted early Saturday the bill would not impact those voluntary agreements.
"We really and truly did work in good faith to try to address those concerns," she said.
