BISMARCK, N.D. (AP) — Gov. Jack Dalrymple told a huge oil industry conference Wednesday that North Dakota would no longer allow flaring of natural gas from oil wells in the Bakken region for longer than one year.

Speaking as part of the Williston Basin Petroleum Conference, which has more than 4,000 people registered, Dalrymple said that North Dakota law allows flaring for one year after production at an oil well begins. After that period, the company must either seek an exemption to continue flaring or install equipment to capture the gas.
