Siemens Water Technologies (or “Siemens”) is a carbon regeneration facility located on the Colorado River Indian Reservation near Parker, Arizona. At this facility, Siemens uses thermal treatment to regenerate the carbon so that it may be used again.
Siemens has been treating spent carbon since 1992. Each year, Siemens receives over 5,000 tons of spent carbon from 30 - 35 states across the United States. Under fifteen percent (15%) of this spent carbon is considered hazardous waste by EPA.
The US EPA is responsible under the Resource Conservation and Recovery Act (RCRA) for permitting carbon regeneration facilities that process RCRA-regulated hazardous wastes on tribal lands.
The Siemens carbon regeneration facility is currently legally operating under “interim status” conditions as prescribed by RCRA. That interim status to continue regulated activities was triggered by the formal submittal of an initial Part A Permit Application, that was endorsed by the Colorado River Indian Tribes (CRIT). CRIT signed as co-applicant on the permit application on December 14, 2009. This restarted the permit application review which was on standby until the CRIT signature was received.
EPA is in the process of making a permit decision on Siemens. In the permit decision, EPA may deny the permit or may issue a permit to allow Siemens to continue processing hazardous waste.
NOTE: Siemens Water Technologies until recently (June 2006) was known as US Filter Westates. EPA is now using the new name, Siemens, in the text of this web page and in new documents that EPA develops. The prior name, Westates, remains in older documents attached to this web page.
