A new bill introduced in the California Legislature, AB 1083, proposes significant rollbacks to the environmental streamlining provisions for advanced manufacturing projects that SB 131 recently established. If enacted, this legislation would narrow the scope of projects eligible for California Environmental Quality Act (CEQA) exemptions, replacing the broad “advanced manufacturing” category with a highly restricted exemption solely for semiconductor facilities. Furthermore, the bill introduces new administrative burdens that could increase litigation risks and compliance costs for a wide range of development projects.
