Liddell Coal - Monthly Environmental Summary – June 2020

1. Dust Gauges

Table 1: Dust Deposition Results – 7 May 2020 to 9 June 2020 (33 Days*)

Notes: * Dust gauges were exposed for 33 days for the June monitoring period due to a scheduling mix up. ** Gauges D55 and D62 are located on privately owned land and are the only gauges that have consent criteria. Insoluble Solids results marked with a ‘c’ indicate an excessively contaminated gauge and are not included in the project average. Contamination can include bird droppings, vegetation (such as plant matter, algae, pollen and seeds) and insects. The twelve-month rolling annual average is calculated from July 2019 to June 2020.
