A methane spike near Porter Ranch is being blamed on routine maintenance according to SoCal Gas.
The utility says the 20-minute increase was not hazardous, but Alexandra Nagy with Food and Water Watch told KFI's Andrew Mollenbeck that people near the leak have been reporting familiar symptoms.
"People have had headaches, nosebleeds, nausea, vomiting, rashes started to appear."
Opponents of the natural gas facility say they're using the latest spike to try and shut down the storage facility.
"No matter how much they say their infrastructure is safe, time and time again they prove it's just the opposite," Nagy said.
A blowout at the Aliso Canyon facility more than two years ago caused the biggest gas leak in U.S. history.
