City of Somerton, Arizona: Wastewater Treatment Plant Reconstruction
EPA is considering the award of a Border Environment Infrastructure Fund (BEIF) grant to the City of Somerton, Arizona, for proposed reconstruction of the existing Wastewater Treatment Plant (WWTP), which is currently unable to adequately treat wastewater and has experienced recurrent NPDES permit violations. The project is also necessary to alleviate existing adverse environmental effects associated with the Somerton WWTP. These effects include the generation of offensive odors, and risks to human health and safety.EPA's involvement in the Somerton, Arizona project is part of a national commitment to improve environmental conditions along the U.S.-Mexico border. EPA participates in the development and implementation of water supply and wastewater infrastructure projects in coordination with the Border Environment Cooperation Commission (BECC) and the North American Development Bank (NADBank). BECC is responsible for certifying projects so that they comply with sound technical, environmental, financial, and public participation principles. NADBank administers the BEIF grants for projects that have been certified by BECC and approved by EPA. For general information, please go to the BECC Web site or the NADBank Web site for project information.
In compliance with the National Environmental Policy Act (NEPA), EPA has prepared an environmental assessment (EA) that analyzes the potential environmental impacts of the proposed project. Based on a review of the EA, EPA determined that the project will not have significant environmental impacts and has issued a Finding of No Significant Impact (FNSI).
