All sewage effluent released to land must be monitored at the frequency and for the parameters specified in Table I1: Contaminant Release Limits to Land.
- I6
The daily volume of effluent release to land must be measured and records kept of the volumes of effluent released.
- I7
When circumstances prevent the irrigation or beneficial reuse of treated sewage effluent such as during or following rain events, waters must be directed to a wet weather storage or alternative measures must be taken to store/lawfully dispose of effluent.
- I8
A minimum area of 5.73ha of land, excluding any necessary buffer zones, must be utilised for the irrigation and/or beneficial reuse of treated sewage effluent.
- I9
Treated sewage effluent must only be supplied to another person or organisation that has a written plan detailing how the user of the treated sewage effluent will comply with their general environmental duty under section 319 of the Environmental Protection Act 1994 whilst using the treated sewage effluent.

Where a term is not defined, the definition in the Environmental Protection Act 1994, its regulations or environmental protection policies must be used. If a word remains undefined it has its ordinary meaning. "acid rock drainage" means any contaminated discharge emanating from a mining activity formed through a series of chemical and biological reactions, when geological strata is disturbed and exposed to oxygen and moisture as a result of mining activity. "AEP" means the Annual Exceedance Probability, which is the probability that at least one event in excess of a particular magnitude will occur in any given year. "affected person" is someone whose drinking water can potentially be impacted as a result of discharges from a dam or their life or properly can be put at risk due to dwellings or workplaces being in the path of a dram break flood. "Airblast overpressure" means energy transmitted from the blast site within the atmosphere in the form of pressure waves. The maximum excess pressure in this wave, above ambient pressure is the peak air blast overpressure measured in decibels linear (dBL). "annual exceedance probability or AEP" the probability that at least one event in excess of a particular magnitude will occur in any given year. "annual inspection report" means an assessment prepared by a suitably qualified and experience person containing details of the assessment against the most recent consequence assessment report and design plan (or system, design plan); a) against recommendations contained in previous annual inspections reports; b) against recognised dam safety deficiency indicators; c) for changes in circumstances potentially leading to a change in consequence category; d) for conformance with the conditions of this authority; e) for conformance with the `as constructed' drawings; f) for the adequacy of the available storage in each regulated dam, based on an actual observation or
