Interesting. I was just going through a file I have and found a Newspaper article dated January 13, 2012. The headline: "Officials: Progress made to ease North Dakota gas flaring". The article is from the Bismarck Tribune and mentions that the amount of natural gas that is torched and wasted daily by drillers in ND's oil patch, could heat more than 2,300 homes in the state for a year. It mentions that some progress was being made.
Another book I read mentions the "Sky Dumps" and health issues along with the waste. Good to see that all of this is being "followed".
