Southern California Gas Co. will pay $8.5 million to settle a lawsuit filed by air quality regulators over the nearly four-month Aliso Canyon gas leak and will fund a study of potential community health impacts.

Under a settlement signed Wednesday with the South Coast Air Quality Management District, the utility will pay $5.65 million in emissions penalties, $1.6 million to reimburse the agency for air-monitoring costs and $250,000 for its legal fees.

The agreement dedicates $1 million to the air district-sponsored health study.
