Freescale Semiconductor, Inc. applied for a renewal AZPDES permit for the proposed discharge of up to 1.44 million gallons per day (mgd) of treated groundwater from the 56th Street and Earll Drive WQARF Site Groundwater Treatment System to the SRP Grand Canal, a Phoenix Area Canal, below municipal water treatment plant (WTP) intakes and all other locations, in the Middle Gila River Basin in Township 1 N, Range 3 E, Section 1, Maricopa County, Arizona. The treatment system includes two extraction wells and an underground pipeline system which conveys groundwater contaminated with trichloroethylene (TCE) to an above-ground groundwater treatment plant. The extraction well water is conveyed through particulate filters for screening and sediment removal and then combined in a pipeline and conveyed for treatment of volatile organic compounds (VOCs) by Granular Activated Carbon (GAC). In-stream monitoring with limitations for boron within a mixing zone, located 1,400 feet downstream of the discharge point, is also required.
