Summary

SB 1039 mandates that a community air monitoring system be installed near every California refinery and that each refinery maintain a fence‑line monitoring system. It also creates a process for refineries to prove a pollutant cannot be emitted, allowing districts to exclude that pollutant from monitoring if evidence shows it’s not released or monitoring is infeasible. The bill places monitoring costs on refinery owners and does not require state reimbursement.
