Fact Sheet: Proposed Permit for the Evoqua Water
Technologies LLC Facility Near Parker, Arizona

(Formerly Siemens, US Filter, and Westates I 2523 Mutahar St., Parker, AZ 85344)

The U.S. Environmental Protection Agency (EPA) is proposing to issue a permit for hazardous waste manage-
ment for the Evoqua Water Technologies LLC facility (Evoqua) near Parker, Arizona. The public has until
November 15, 2016 to provide comments on the proposal and its accompanying draft permit. A public hearing
on the proposal will be held by EPA 011 November 1, 2016 at the Bluewater Resort and Casino in Parker.

Facility Description

Evoqua operates a carbon regeneration facility located on the Colorado River Indian Tribes (CRIT) reserva-
tion near Parker, Arizona. Evoquas process involves treating spent carbon in a regeneration furnace to purify
it and make it available for reuse as a commercial product. The spent carbon that is shipped to the facility has
been used to remove contaminants from air emissions and contaminated water at industrial and cleanup sites
throughout the nation. Annually, the Evoqua facility receives over 5,000 tons of spent carbon from 30 - 35 states
across the United States. About 11% of this spent carbon is considered hazardous waste and is regulated by EPA.

RCRA Regulatory History

Under the Resource Conservation and Recovery Act (RCRA), EPA is responsible for permitting facilities that
manage RCRA-regulated hazardous wastes on tribal lands. Starting in 1991, EPA required new carbon regenera-
tion furnaces to obtain hazardous waste permits. At that time, the Evoqua facility (then known as US Filter/
Westates) was already undergoing construction of a carbon regeneration furnace which meant it was eligible to
operate under "interim status" RCRA regulations while applying for a RCRA hazardous waste permit.

The first part of the permit application for the Evoqua facility was submitted to EPA in 1995. There have been
several sets of comments and requests for information from EPA that Evoqua addressed. As a result, several
revisions to the permit application have been submitted by Evoqua to EPA. On May 9, 2016 EPA found that the
permit application - signed by both the operator, Evoqua, and the beneficial landowner, CRIT - was complete.
