Lawmakers this week made good on a year-old promise, passing a bill to narrow a controversial exemption from California’s environmental review law. The proposal passed both houses of the Legislature and now goes to the governor’s desk. Senate Bill 954 follows through on a pledge state legislative leaders made last year, when Gov. Gavin Newsom threatened to withhold approval of a $300 billion spending plan unless lawmakers passed sweeping changes to the California Environmental Quality Act.  Lawmakers complied by passing Senate Bill 131, which exempted “advanced manufacturing facilities” from environmental review. But more than 30 lawmakers objected to how broad that exemption could be, because it could increase pollution in already vulnerable communities. They pledged to narrow it this year.
