and sub-soil strata every two years.

Soils monitoring shall include analysis of soil pH, Sodium Adsorption
Ratio, Calcium/Magnesium Ratio, Exchangeable Cations, Total
Cations, Electrical Conductivity, Nitrogen, Phosphorous, Calcium,
Magnesium, Chloride and Sodium. Gypsum/lime shall be applied to
soils as indicated by the results of soil monitoring and analysis.

Baseline monitoring of groundwater quality shall be undertaken
quarterly for one year prior to the commencement of construction.

Monitoring of groundwater quality shall be undertaken quarterly
during construction and for 2 years after construction works and
annually thereafter or as specified by the conditions of the
development approval. Groundwater monitoring points shall be
established up-gradient and down-gradient of the STP, the effluent
storage lagoon and the irrigation area.

Groundwater monitoring shall include analysis of pH, Electrical
conductivity, Total dissolved solids, Biochemical oxygen demand,
Sodium, Salinity, Chloride, Sulfate, Alkalinity, Nitrate and Nitrite,
Ammonia, Total Nitrogen, Total Phosphorous and Faecal coliforms.

Groundwater depths shall be determined quarterly during
construction and for two years following construction and annually
thereafter.

Surface water quality monitoring shall be undertaken of runoff from
irrigation areas where there is a minimum of 30 mm rainfall in the
preceding 24 hours sufficient to cause runoff from the irrigation area.

Surface water monitoring shall include two event samples of runoff
from the irrigation areas collected annually, and analysed for pH,
Total Nitrogen, Total Phosphorus, EC, and Faecal Coliforms.

Monthly monitoring shall include a visual inspection of the condition
of the vegetation and evidence of soil erosion within irrigation areas.

Regular inspection of the stormwater diversion infrastructure around
the irrigation area shall be undertaken on a weekly basis.

 

REPORTING/
RECORDING:

Operators shall submit monthly reports to Council during
construction and establishment phases providing details of all
monitoring results, environmental incidents and emergencies and
corrective actions undertaken.

Accurate records shall be maintained of all monitoring results. These
monitoring results shall be forwarded to the EPA as part of the
annual report.

Any signs of soil erosion or deterioration of vegetation health shall be
noted and appropriate corrective actions taken and recorded.

 

 

CORRECTIVE
ACTION:

 

 

Should there be non-compliance with the stated performance

indicator the following corrective actions are to be implemented.

e Identification of the cause of the non-compliance;
