Los Angeles City Attorney Mike Feuer on Tuesday filed suit against the operators of a controversial South Los Angeles oil field with operations that have been blamed for noxious vapors causing health problems.

Feuer is seeking a permanent injunction and civil penalties against Allenco Energy Co. of Signal Hill, and company principals James Allen and Timothy James Parker.

In November, Allenco voluntarily agreed to suspend oil production at the two-acre University Park site on West 23rd Street, which is about one half a mile north of the University of Southern California and next to Mount St. Mary’s College and a residential area.

Allenco has leased the land from the Archdiocese of Los Angeles since 2009. Complaints about the oil field operation increased in 2010 after Allenco boosted production at the wells by more than 400 percent. The field also under investigation by the U.S. Environmental Protection Agency, the South Coast Air Quality Management District, the L.A. County Department of Health and the Archdiocese.

An employee answering the phone at Allenco’s main offices said the company had not been notified about the lawsuit and that company officials were not available to comment.
