Article Photos: In '72, EPA battled pollution; now it's politics 22/37

  This June 1972 photo released by the U.S. National Archives shows a sunrise over the Olin-Mathieson Plant on the Calcasieu River in Calcasieu Parish, La. The photo was taken for the "Documerica" program, 1972-1977, instituted by the then new Environmental Protection Agency to document subjects of environmental concern.
