Following escalating urgency over the leaking gas well above Porter Ranch, 300 protesters gathered on Saturday, Dec. 12, 2015, and demanded an immediate shutdown and a transition to renewable energy in the next two decades. They gathered near the SoCalGas Aliso storage facility entrance in Porter Ranch. Residents across Porter Ranch have complained for weeks about the health effects of a widespread natural gas leak that has sparked calls for local, state and federal action.
