First, N Slope production began in 1981, peaked in 1988 and then has slowly and steadily declined over the next 28 yeasrs. Second there were no "grandfathered" exporting areas since any oil from any well in the lower 48 was free to be exported. And why: because no "export ban was put into effect." Look at the chart closely: more US oil was exported during the year AFTER the "ban" was signed into law then the year BEFORE it was signed. And one more f*cking point so many don't get: the oil export "ban" law specifically allows oil to be exported to Canadas with NO RESTRICTIONS WHAT SO EVER! And guess what country has received the vast majority of US EXPORTED OIL. Do I have to give the answer? LOL.
More about N Slope oil. From
http://www.snopes.com/politics/gasoline/alaskaoil.asp"We don't need to engage in such economic speculation to debunk the rumor that all crude oil produced in Alaska is currently shipped to Japan, however. The Trans Alaska Pipeline Authorization Act of 1973 effectively required all petroleum from Alaska's North Slope (ANS) to be sent to U.S. refineries. Congress passed legislation in 1995 eliminating that requirement, but: Alaskan crude oil exports effectively ended by May 2000 (due largely to allegations that British Petroleum had shipped ANS crude to Asian buyers in order to prop up flagging prices on the U.S. West Coast, claims which prompted legislators to begin calling on President Clinton to reinstate the ban on Alaskan oil exports). Even during the period between 1996 and 2000 when ANS crude was being shipped abroad (primarily to China, Japan, and Korea), such exports accounted for only 7% of total ANS production."
I'm sorry but I can't begin to imagine what goes thru a person's mind who sees the data just presented and still thinks there has been any regulatory restriction to exporting US oil ever since the Texas Rail Road Commission lost that power. And actually the TRRC hasn't lost the power to restrict Texas oil production: the "allowable regulations" are still the law here. Every month the Commission meets and sets the allowable for the next month. But since the early 70's it has always been set at 100%. But for whatever reason they wanted to reduce Texas oil production in half they could set the allowable at 50%.
And again the FACT that US oil exports have been ongoing for many decades still isn't THE BIG ISSUE: in 2015, before the POTUS allegedly ended the oil export "ban", refinery products made from TEN TIMES AS MUCH OIL as we exported were EXPORTED out of the US.
Sorry for being so redundant but it's really difficult to make some folks see when they refuse to open their f*cking eyes. LOL.
