Hydraulic fracturing (fracking) has been carried out in New Zealand for over 23 years〔 but concerns have been raised by environmentalists about its negative effects. Some local government jurisdictions have called for a moratorium on fracking but this has been rejected by the government. The environmental effects of fracking are potentially regulated by the Resource Management Act (RMA) through the requirement for resource consents. In 2011, the Taranaki Regional Council published a report that found there had been 43 hydraulic fracturing activities in 28 wells with no evidence of any related environmental problems. The report also found that the risk of contaminating freshwater aquifers was very low. Since August 2011, the Taranaki Regional Council has required resource consents for all subsurface fracturing discharges.〔(【引用サイトリンク】 title=Hydrogeologic Risk Assessment of Hydraulic Fracturing for Gas Recovery in the Taranaki Region )〕 In 2012, the Parliamentary Commissioner for the Environment undertook an investigation into the environmental impacts of fracking in New Zealand. The interim report stated that environmental risks can be effectively managed, and the second phase of the investigation will focus on how environmental risks are regulated and monitored.〔 In 2013, the Prime Minister John Key stated that hydraulic fracturing had been going on safely in Taranaki for the past 30 years without any issues. ==History== Fracking has been carried out in the Taranaki Region since 1993 and the technique has been used on about 30 wells in the Taranaki and Waikato Regions since 2003. L&M Minerals have applied for exploration permits for coal seam gas extraction off the coast of South Canterbury and on the Canterbury Plains. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hydraulic fracturing in New Zealand」の詳細全文を読む スポンサード リンク
