California Moves toward Pollution Protections for Outdoor Workers near Border Rivers

SB 1046 requires Cal/OSHA to propose safety standards for lifeguards, park rangers and other high-risk employees by 2030.

Outdoor workers facing high or prolonged exposure to pollution near the Tijuana and New rivers could receive new workplace protections under legislation signed by California Gov. Gavin Newsom.

SB 1046 requires Cal/OSHA to submit a proposed standard to the Occupational Safety and Health Standards Board by Jan. 1, 2030. It must cover lifeguards, park rangers and other employees Cal/OSHA identifies as high risk who work within 10 miles of specified river, park and wildlife-refuge boundaries.

The proposal may address personal protective equipment, medical monitoring, hazard communication, exposure reporting, recordkeeping and training for employees and supervisors. Cal/OSHA must also consider establishing a hydrogen sulfide exposure threshold for the standard.

The law permits Cal/OSHA to consult affected workers, employers, labor unions, local governments, air districts, public-health agencies and academic institutions while developing the proposal. The measure takes effect Jan. 1, 2027.
