None - Environmentalists were challenging a project this week that could bring with a high impact on Oklahoma's economy and, according to some, a boost to national security. Portions of the Keystone XL pipeline from Nebraska to Cushing, Oklahoma, are already in operation. In question is a government permit to allow the rest of the project to get underway. Kansas Gov. Sam Brownback said he supports the pipeline because it would boost national security by giving the U.S. a steady source of oil from a ``friendly nation that's next door.'' At a State Department hearing in Kansas Monday, Rabbi Moti Rieber, coordinator of Kansas Interfaith Power & Light, joined the procession of speakers Monday. The religious and environmental group leader called the pipeline``a direct threat'' to Kansas' natural resources because of possible spills. Unions are in favor of the line as is the governor of Kansas. The governor of Nebraska opposes it for environmental reasons. The oil bearing line would stretch from oil fields in Alberta, across the U.S. border, and through the Midwest to the Gulf of Mexico. Stops along the way include refineries like the one in Cushing. Some government estimates say as many as 200,000 jobs would be created, with some 15,000 of those being high-wage construction jobs, ala the Alaskan pipeline in the 1970s. Many of those jobs could put Oklahomans to work. In addition, TransCanada, the company building the pipeline, claims on their website that more than $1 billion could be pumped into Oklahoma's economy, with an incease in personal income of more that $800 million. The 36-inch line would carry crude oil south through states like Nebraska and Kansas before running through Oklahoma. The State Department plans to hold hearings in Texas and Montana this week.
