This bill amends the California Environmental Quality Act (CEQA) by requiring the Public Utilities Commission (PUC) to certify the environmental impact report for priority electrical infrastructure projects within 270 days of determining the application is complete. The bill defines a priority project and mandates that the applicant identify this designation in the application, specifying the basis for it. PUC staff must review applications within 30 days, notifying applicants of any deficiencies, which must be corrected or explained within 60 days. Once deficiencies are addressed, the PUC will issue a preliminary ruling, setting the scope and schedule for the project.
