William Least Heat-Moon’s article “Water World” (April) is great with one exception: The caption for the picture on the last page is in error. First, the subject is not a refinery. It is a natural-gasfueled electrical power plant owned and operated by the Cleco Corporation, an investor-owned NYSE-traded electric company headquartered in Pineville, Louisiana. Second, the emissions from the facility are not “fumes.” What is being emitted is water vapor.
