On 30 September 2019, the Department issued a $15,000 Penalty Notice to Warkworth Mining Limited for a blast that occurred at the Mt Thorley Warkworth coal mine on 4 April 2019. The air-blast overpressure from the blast exceeded the blast criteria of the development consent at the Warkworth monitoring station. Air blast overpressure limits are in place to minimise disturbance to community members. The mine has committed to improve their predictive meteorological tools and explore other measures to avoid similar occurrences, which will be reflected in an updated Blast Management Plan.
