SAN FRANCISCO –The U.S. Environmental Protection Agency is extending the public comment period on its proposed hazardous waste permit for Evoqua, a commercial carbon regeneration facility on the Colorado River Indian Tribes reservation near Parker, Arizona. 

The public comment period has been extended through January 9, 2017.

The Evoqua facility has been operating since the mid-1990s, treating spent carbon in a regeneration furnace to purify it and make it available for reuse as a commercial product.  EPA’s proposed permit, if finalized, will be valid for 10 years and will allow Evoqua to store and regenerate carbon, some of which is contaminated with hazardous waste.

A permit ensures that the facility will operate in a manner to protect human health and the environment.  The facility is currently operating under interim hazardous waste regulatory requirements.  The proposed permit will impose stricter requirements that Evoqua must follow, including the most stringent environmental controls for this type of facility in the nation.

EPA will make a final decision on the permit after carefully considering all public comments submitted.
