SUGAR LAND, TX--(Marketwired - Oct 18, 2013) - Written by John Egan for Industrial Info Resources (Sugar Land, Texas) -- The owners of the Navajo Generating Station (NGS) may have to pay several hundred million dollars to reduce air emissions from the massive power plant, located about 20 miles from the Grand Canyon in northern Arizona. But the owners don't yet know exactly how much they will pay, or when, or what pollution control technologies they will be installing. Despite those critical uncertainties, the owners are happier now than they were in early 2013, when a draft regulation from the U.S. Environmental Protection Agency (EPA) (Washington, D.C.) could have required them to install as much as $1.1 billion of pollution-control equipment by 2018.
