By Kristen Hays SAN ANTONIO, Texas, March 23 (Reuters) - Colonial Pipeline has withdrawn a revised tariff that sparked complaints from several shippers who say it would hurt access to the critical gasoline and diesel artery and limit competition, according to a regulatory filing. The tariff would change how space is allocated on the largest refined product pipeline system in the United States, which has been full for three years. Colonial withdrew the new tariff in a filing to the Federal Energy Regulatory Commission made public on Monday - which the agency suspended last week - to talk with shippers regarding how they exchange their shipping history on the pipeline to maintain space to move products. Colonial moves more than 3 million barrels per day of gasoline and distillates from the U.S. Gulf Coast to the Northeast. The pipeline assigns space based on shipper history, or how many barrels shippers regularly move in 72 cycles throughout a year. So-called regular shippers move an average of 18,750 barrels per cycle. Shippers routinely transfer their shipper histories back and forth to maintain the consistent status of a regular shipper so they don’t have to settle for what they can get of the 10 percent or less space left available. The revised tariff would stop the practice of transferring shipper history unless a regular shipper buys another regular shipper’s business. Several shippers say that would relegate smaller customers to scrambling for tidbits of open space. “Colonial is withdrawing the filing in order to engage in further consultation with shippers regarding the issue of volume history transfers,” the company said in the filing, without elaboration.
