Whitehaven Coal Limited : Annual Report 2013
45 Whitehaven Coal Limited Annual Report 2013 5 Environment In FY2013, our environmental team introduced InViron technology to our business, enabling us to integrate and maintain large volumes of environmental-related data from all of our operations, into a centralised database. This accumulation of data ensures we have e ective control over day-to-day management, monitoring, analysis and reporting, based on set targets and objectives, and allows us simple access to our data in the most e cient way possible. A wide range of environmental data is tracked across air, water, land and waste issues and is fully integrated with our environmental analysis laboratories to ensure current, accurate analysis and timely alerts in the event that any analysis result exceeds compliance criteria. Case Study INVIRON Mitigation e orts include, but are not limited to: • Where practicable, soil stripping is undertaken at a time when there is su cient soil moisture and low winds to prevent signi cant dust lift-o . • Dust suppression by application of water by water carts, with high use roads regularly watered. Site access roads are sealed. • Drill rigs utilise water injection or alternatively, are tted with dust collectors. • Blasting is conducted before the establishment, or after the break up of, low-level atmospheric temperature inversions. • Predictive meteorological forecasting and predictive air dispersion modelling, together with real time monitoring data, will be used to inform operational practices in advance of the commencement of shift. • All roads are speed limited and enforced to ensure that dust generation is at acceptable levels. • All conveyors are tted with appropriate cleaning and collection devices to minimise the amount of material falling from the return of conveyor belts, and sprays are used to reduce ne dust. • Trucks transporting coal o site from the Coal Processing Area must are covered immediately after loading. • Exhausts on earthmoving equipment and on-site vehicles are compliant with NSW EPA emission requirements and have the exhausts directed upwards or to the side (where applicable) so as not to cause dust lift-o . • Some exibility exists to temporarily cease operation in the event of protracted dry periods, high winds, or signi cant dust generation and dispersal towards the surrounding residences.
