Strict emissions curbs have been loosened on a major gas plant harming nearby ancient rock art after Woodside warned they amounted to an “effective refusal” of the project. New federal documents also reveal Environment Minister Murray Watt agreed industrial emissions from the resources giant’s gas plant were harming the World Heritage-listed rock art in Western Australia’s Pilbara region. “The federal conditions provide clarity on the modifications required at the Karratha Gas Plant that will support processing of other resource owners’ gas,” the spokesperson said.
