Pollution Incident Response Management Plan

Introduction


1.1 PURPOSE
This Supporting Statement and PIRMP have been prepared in accordance with the Protection of the
Environment Legislation Amendment Act 2011 (POELA Act) and reflects the requirements specified in
the Environment Protection Authority’s (EPA’s) Guidelines: Preparation of pollution incident response
management plans, March 2012.


The PIRMP details:

  • Procedures for notifying a pollution incident to relevant persons;
  • Actions to be taken to reduce and/or control pollution; and
  • Procedures for co-ordinating those notified and any action taken in combating the pollution.


1.2 DEFINITION OF POLLUTION INCIDENT
A pollution incident is required to be notified if there is a risk of ‘material harm to the environment’,
which is defined in section 147 of the POEO Act 1997:

“(a) harm to the environment is material if:

i) it involves actual or potential harm to the health or safety of human beings or to ecosystems
that is not trivial, or
ii) it results in actual or potential loss or property damage of an amount, or amounts in
aggregate, exceeding $10,000 (or such other amount as is prescribed by the regulations),
and

(b) loss includes the reasonable costs and expenses that would be incurred in taking all reasonable and practicable measures to prevent, mitigate or make good harm to the environment.”


1.3 IDENTIFIED POLLUTION INCIDENT RISKS
The primary potential hazards to human health or the environment associated with the activity
undertaken at this site – i.e. ‘Pollution Incidents’ - include the following:

  • Identifying non-domestic quantities (more than 200 millimetres per tonne or 200 grams per
    tonne) of hazardous substances among waste;
  • Surface or subsurface fires;
  • Mixing of leachate and stormwater or waste and stormwater;
  • Identification of any failure of an environmental protection system;
  • Identification of a significant difference in groundwater indicator parameters;
  • Confirmation of surface gas at the landfill at greater than 1.25 per cent methane (volume for
    volume);
  • Confirmation of gas accumulated in buildings at greater than 1.25 per cent methane (volume for volume);
  • Acts of vandalism or target of terrorist activity; or
  • Any other incident or observation that could potentially pose an immediate environmental
    hazard outside normal operating conditions.
