NSW Environment Minister Robyn Parker has dismissed calls for her resignation over the botched handling of the Orica chemical leak at Newcastle, instead calling a scathing report into the accident "political" and "unnecessary".
The upper house committee's report into the August 8 hexavalent chromium leak, which sent a chemical plume over the nearby suburb of Stockton, lays most of the blame for the debacle at Orica's feet.
But Ms Parker is also criticised for taking until August 11 to notify the public of the leak at the Kooragang Island plant - three days after the accident and almost 24 hours after she was informed of the accident.
The failure to tell locals sooner - which the report blamed on Orica, the Office of Environment and Heritage (OEH) and Ms Parker - meant "many in the Stockton and surrounding communities (were) living with a great deal of uncertainty and fear for longer than was necessary".
Opposition leader John Robertson in question time demanded Ms Parker resign over the bungled handling of the leak.
However, the environment minister dismissed calls for her head, labelling the upper house inquiry "political" and unnecessary after the government-commissioned O'Reilly report into the leak, which was released in October.
"This government has acknowledged that the incident on August 8 caused by Orica was unacceptable. It let down the people of Stockton and surrounding areas," Ms Parker said.
"We've already acknowledged that there were failures in systems and reporting, starting with Orica taking so long to report."
Opposition environment spokesman Luke Foley, who sat on the inquiry, said the report "should be the final nail in the coffin of environment minister Robyn Parker".
"It is a damning indictment of her failure to protect the people of Stockton," he said.
"It is long overdue the premier does the responsible thing and dismisses Robyn Parker as a minister in NSW."
In its findings, the committee said Orica's approach to addressing the potential of a leak was "grossly inadequate", and its failure to inspect Stockton until midday the day after the leak was an "inadequate response".
Orica's delay in notifying the OEH was also "unacceptable", while its emergency response plan was "not sufficiently clear or comprehensive".
The company's failure to notify NSW Health until more than 41 hours after the chemical leak "demonstrated a lack of urgency in addressing the potential for public health risks to communities in Stockton".
The report also criticised the OEH for its "unacceptable" delay in notifying the minister of the leak. Ms Parker was not notified until two days after the accident.
WorkCover should have visited the plant earlier than 50 hours after the leak, the report said.
It makes seven recommendations, including that the premier provide "clear and unambiguous" guidelines to all ministers specifying the timing of public health or safety notifications.
The committee also called on the OEH to amend its procedures so information was passed to other agencies in a more timely manner.
In a brief statement, Orica said it was reviewing the report and would "respond in due course".
The Nature Conservation Council of NSW said the report showed there was a need for stronger regulation of facilities such as the Kooragang Island plant.
