California Sen. Barbara Boxer has called on an oil company to stop production at its Los Angeles facility after some residents complained of nosebleeds, headaches and dizziness.
The Democrat appeared Friday with residents in the University Park neighborhood in South Los Angeles. A nearby oil field ramped up production in recent years due to rising crude oil prices and new extraction techniques.
Residents have blamed the chemical odors for their health problems.
State air regulators have taken air samples in the neighborhood but have not found dangerous fume levels.
Allenco Energy Co. leases land from the Archdiocese of Los Angeles for its operations, located near the University of Southern California campus.
No one answered the phone at Allenco's office in Los Angeles.
