WICET wins 2015 Clean Air Achievement Award

THE Wiggins Island Coal Export Terminal (WICET) has been recognised for its design emphasis on air quality.

WICET won the 2015 Clean Air Achievement Award at the Clean Air Society of Australia and New Zealand (Queensland Branch) Achievement Awards held on 9 October 2015.

WICET CEO Marcus McAuliffe said the award was testament to the company's commitment to minimising its impact on air quality.

"We are delighted to have won the 2015 Clean Air Achievement Award in recognition of WICET's outstanding contribution to an improvement in the air environment and to the control of air pollution." Mr McAuliffe said.

The new coal terminal has been designed to minimise all impacts on its surroundings, while providing flexibility for future capacity increases.

WICET's design philosophy aims to prevent or minimise, rather than to simply mitigate, the impacts of dust and noise is reflected throughout the site:

  • WICET is situated downwind from the City of Gladstone under all prevailing strong winds.
  • Coal trains bypass all residential areas.
  • The rail receival facility is fully enclosed to minimise noise emissions and uses duplicated negative
  • pressure bag filter systems to prevent dust escape.
  • The 5.6 km overland conveyor is fitted with a tight overhanging roof to minimise dust escape.
  • A gantry stacker provides precise placement of coal onto multiple stockpiles, including blending, with
  • minimal dozer use.
  • The stacker is fitted with telescopic nozzles (incorporating counter-flow misting sprays) which
  • minimise free fall of coal and control dust lift-off.
  • Underground reclamation tunnels are equipped with vibratory feeders to facilitate coal recovery, and
  • permit further blending, with minimal use of dozers.
  • All overwater conveyors have roofs, walls (on the upwind side) and floors to prevent dust lift-off in
  • strong winds.
  • The ship-loader boom is fully enclosed with a roof, walls and floor.
  • All dust and coal water from the wharf and jetty is transported back to shore via a slurry system and
  • recycled.
  • A network of intelligent monitoring units around the site continuously analyse air temperature,
  • relative humidity, wind speed and direction, and incorporates state-of-the-art Beta Attenuation
  • Monitor (BAM) technology to continuously dust (PM10 and TSP) levels. This data is seamlessly
  • integrated into the site master control system.
  • Real-time trend analysis triggers the targeted application of moisture in defined patterns via 51
  • stockyard water cannons.
  • In addition, sprayers in all transfer towers apply additional moisture, whenever required.
  • All belt return units are fitted with belt cleaning equipment which captures coal dust for return to
  • settlement ponds.
  • Process water is recycled on site.
