Agenda item 6 – Environmental Performance Surface water Quarterly monitoring round undertaken in September and November 2018 Due to lack of rain only 3 sites sampled – no flow onto the site. Analyses now compared to trigger levels Next sample round March 2019 Total Nitrogen for T1 is in compliance, levels in the dam have always been higher but have decreased during 2017 and leveled off. Marulan south creek increasing and may be due to lack of flow of water 21

Agenda item 6 – Environmental Performance Surface water Total dissolved solids in compliance with the exception of Marulan south creek – due to low flow Turbidity In compliance with the exception of the dam following rain event of 43mm in the preceding 24hours 22

Agenda item 6 – Environmental Performance Surface water pH in compliance for the last rounds of sampling Total phosphorus - In compliance for T1 but showing fluctuations for the dam. May be due to changes in water level introducing nutrients from above the site and / or an increase in water fowl population in the dam. Marulan south creek shows a similar pattern, with a decrease in September and an increase following the rain event in November 2018 23

Agenda item 6 – Environmental Performance Ground water  No draw down of ground water from sentinel well .i.e. no impact on local groundwater. 24
