Greens NSW mining spokesperson Jeremy Buckingham asked that Premier Barry O'Farrell visit residents in the Sydney western suburb of Menangle Park to explain why his government allowed an AGL production CSG well to be approved without local residents being notified.

"The premier proudly took responsibility as the minister for Western Sydney, so it is incumbent on Mr O'Farrell to explain to residents at Menangle Park why his government allowed a coal seam gas well to be approved near their homes without any notification," Buckingham said.

"Both Campbelltown Council and the Environmental Protection Agency insisted that local residents be notified and consulted regarding the proposal for a new coal seam gas production well only 40 metres from the Nepean River and within earshot of their homes.

"It's a disgrace that there has been no real consultation with local residents about this coal seam gas well.

“Although residents had been kept awake all night by noise and lights, they didn't know the cause was AGL drilling for gas until I knocked on their doors and told them what was going on.”

Buckingham said the government had no regulatory response to the CSG industry's plans to operate in urban environments.
