The air in Ascension Parish is already saturated with the pungent odor of ammonia, a scent reminiscent of strong cleaning products or even cat urine. Of the nation’s counties, Ascension Parish is one of the most polluted. Now, the company has joined with many corporate partners to expand its capacity, in a way that could truly turn Ascension Parish into Ammonia Parish, further sickening neighboring communities, residents and environmental advocates fear. Now, residents seem worried that, with ammonia production slated to quadruple, Ascension Parish residents will be exposed to a marked increase. At least one local leader sees CF Industries’ commitment to expansion in Ascension Parish as a win for the parish.
