Oil fell below $100 a barrel Monday as investors and economists await a key OPEC meeting this week and the government's outlook on U.S. supply and demand, according to AP. Benchmark West Texas Intermediate for July delivery lost 62 cents at $99.60 per barrel in midday trading on the New York Mercantile Exchange. Crude has hovered around that level for a month. A stronger dollar pushed oil lower. TransCanada Corp. also said its Keystone Pipeline was back online after a minor oil spill at a pump station in Kansas. The pipeline delivers a half million barrels of oil per day to the U.S. from Alberta, feeding supplies to the delivery point for benchmark oil in Cushing, Oklahoma. The 1,300-mile (2,080-kilometer) pipeline was taken offline twice in the last month as TransCanada dealt with leaks. Analysts are looking for clues on what OPEC will do about oil production when the it meets Wednesday in Vienna. -- SPA
