Community Information Fact Sheet for the
Evoqua Water Technologies LLC Fact ity Near Parker, Arizona

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

Evoqua Water Technologies LLC (Evoqua) operates a carbon regeneration facility located on the Colorado River
Indian Tribes (CRIT) reservation near Parker, Arizona. Evoqua's process involves treating spent carbon in a
regeneration furnace to purify it and make it available for reuse as a commercial product. The carbon Evoqua
receives has been used to remove contaminants from air emissions and contaminated water. Annually, Evoqua
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 the U.S. Environmental Protection Agency (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. Like Evoqua (then known as US Filter/Westates), several
facilities were already operating or had begun construction on carbon regeneration furnaces. These pre-existing
facilities operate under "interim status" regulations while applying for a RCRA hazardous waste permit.

The first part of the permit application for the Evoqua Parker 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.

Current Status

Evoqua certified the latest application submittal on March 17, 2016. CRIT, the beneficial landowner of the
tribal land where the facility is located, is a co-applicant on the permit application. On April 8, 2016, the CRIT
Tribal Council passed a resolution to endorse their December 2009 signature on the permit application. Two
co-applicants' signatures made the application complete. The application was submitted on April 25, 2016, and
was effective May 9, 2016.

After EPA staff reviews the complete permit application, EPA will announce a tentative decision on whether to
issue or deny the permit and will open a 45-day public comment period. The complete application is available
online at the link shown below. Copies can also be found at the locations indicated below. Please note that
earlier documents, including on EPA's website, may still use previous facility names such as Siemens, US Filter,
and Westates.

Community Involvement

EPA would like to hear from you during the 45-day public comment period that will be announced at a future
date. A second fact sheet will be mailed out announcing the start of the public comment period and other
pertinent information. During this period, EPA will hold a public meeting in Parker, Arizona. At the public
meeting, general information will be provided about the facility. At the close of the informational public meet-
ing, EPA will open a formal hearing during which the public may present comments regarding the tentative
decision directly to EPA officials. Public comments may be submitted to the Agency during the entire 45-day
comment period.

The complete application is currently available to the general public for review or copying and can be found at
