Penalty for delayed reporting of incident

As per reports, a gas production facility will be penalized upto  $ 50,000 for alerting the authorities 2 hrs late about bursting of gas and salt water from one of its wells. This appears to be of very high standards, as generally many incidents including gas leak go without reporting.  In another facility of the same facility, spilled diesel was contained and contaminated soil was removed. Again, this is also great as nobody cares about spillages even outside facilities and replacing the soil within the facility is a good move. Australian authorities appear to be strict in respect of rules and regulations and is better for safety of the people, if it is implemented in toto everywhere.
