The Snowy Hydro Corporation in the New South Wales Snowy Mountains is stepping up its cloud seeding program after receiving the go-ahead from the State Government.
The Government legislated earlier this year to allow the seeding trial to become permanent.
Snowy Hydro spokesman, David Hogan, says the nine-year trial shows the program is effective, increasing snow falls by 14 per cent with no environmental or downwind impacts.
He says monitoring will continue to ensure the silver iodide seeding agent is not accumulating in ecosystems.
‚??The Natural Resources Commission and New South Wales Government say they've seen no change to background levels, but we'll continue to monitor that just in case,‚?? Mr Hogan said.
‚??There may be some change to that.
‚??But what we're seeing with our scientific team and other independent science and research partners is they're not expecting to see any change to background levels but importantly we'll keep monitoring that.‚??
Mr Hogan says he‚??s unable to say what increase there is to water flowing into the used by the hydro electricity scheme.
‚??We're still doing some modelling because year on year catchment conditions can change,‚?? he said.
‚??We're going to get some numbers on that.
‚??The way I like to put it, it wouldn't be worth our while to keep putting in the million or so dollars a year it takes to do it.‚??
