City updates residents on Hyperion maintenance, mosquito counts and odor complaints
Summary
City manager reported higher mosquito counts near Hyperion linked to maintenance activities; staff have been pumping standing water and the South Coast Air Quality Management District logged about 27 odor complaints in two weeks but issued no notices of violation.
City Manager Darryl George provided an update on Hyperion operations during the May 6 City Council meeting, saying recent maintenance work at the Hyperion plant is the likely cause of increased mosquito counts reported by nearby residents.
George said plant maintenance—work on primary tanks and intermediate pumps—has created standing water in some areas, and plant staff have been locating potential breeding sources and pumping down standing water. Over the prior two weeks, the South Coast Air Quality Management District had received roughly 27 odor complaints about the facility; the facility was not issued any notices of violation during that period, George reported. The second edition of the Hyperion pipeline newsletter for March 2025 was released with updates on education and improvements at the facility. City staff directed residents to the city’s Hyperion webpage for more information.
The city’s report was informational; council did not adopt additional actions during the May 6 meeting, and staff said they would continue maintenance and monitoring and take appropriate measures to address standing water and community concerns.
