An oil discharge into Botany Bay during heavy rain last month has highlighted the potential impact that industry and natural weather events can have on our urban waterways.
Following the release of oily water into Botany Bay by Caltex Refineries as part of the company’s stormwater management emergency procedures at its Kurnell premises, oil was blown to the northern shoreline and onto rock platforms at Congwong and Little Congwong beaches. NSW Environment Protection Authority Chief Environmental Regulator Mark Gifford said businesses, individuals, emergency response services and regulatory authorities such as the EPA all have a role to play to prevent and/or minimise impacts to the environment during such incidents.
“While pollution incidents can often be exacerbated or even caused by extreme weather events such as heavy rain, environmental impacts such as that which occurred following this incident on 24 March are unacceptable,” said Mr Gifford. “Industries regulated by the EPA under Environment Protection Licences (EPL) have a duty to report pollution incidents threatening or causing harm to the environment, and are required to prepare Pollution Incident Response Management Plans. “The EPA also relies on members of the public who are aware of pollution to report incidents so the appropriate authorities can act as soon as possible.” There are a number of regulatory authorities who respond to water pollution incidents, including councils, marine authorities and Sydney Water, but in the first instance people can call the EPA’s Environment Line, 131 555, 24 hours a day seven days a week to report incidents. The appropriate response agency is determined by the nature, size, source and location of the water pollution incident. Typically, small incidents are managed by the local council, but if the incident involves hazardous materials, an emergency response service such as Ports Authority, Roads and Maritime Services or NSW Fire and Rescue will be the lead combat agency in charge of the initial clean-up. The EPA provides assistance and advice to combat agencies during incidents when requested and investigates suspected breaches of environmental laws. “Regardless of whether or not the EPA has been asked to assist during an incident, as the state’s lead environmental regulator we will always have officers on standby to attend and assess any environmental impacts,” said Mr Gifford.
“The EPA takes into account a range of factors when determining our response to pollution incidents. This includes the degree of environmental harm, health impacts, community expectations and the actions of the offender,” said Mr Gifford. “We have a range of regulatory tools we can use to achieve environmental compliance, including formal warnings, clean up or prevention notices, mandatory audits, enforceable undertakings, penalty notices, legally binding pollution reduction programs and prosecutions. “Our regulatory response is designed to hold the polluter to account, raise awareness about the problem, encourage behavioural change and repair any environment damage.” In the case of the Botany Bay incident, the EPA issued Caltex with clean-up notices to implement an ecological assessment program. The EPA is also conducting a detailed investigation into the incident.
