EPA has made a finding of No Adverse Effect for its Resource Conservation and Recovery Act (RCRA) permit decision with respect to the Evoqua Water Technologies facility in Parker, Arizona. This means that, whether EPA approves or denies the facility's permit application, there would be no adverse effect on historic or culturally significant properties. The following fact sheet summarizes this finding and its relationship to the hazardous waste permit decision-making process.
