| Objectives | Waste Discharge Requirements (WDRs) Order Nos. 94-166 abd 95-109 (NPDES Nos. CA0081833 and CA0083739) were adopted on 24 June 1994 and 26 May 1995, respectively. Herafter, NPDES Permit No. CA0083739 is discontinued from use and NPDES Permit No. CA0081833 will reference all disharges described herein. WDRs Order No. 94-166 regulates the discharge from an on-site-air-stripping unit of treated groundwater and WDRs Order No. 95-109 regulates the discharge of treated groundwater from two off-sites Granular Activated Carbon (GAC) groundwater treatment systems. Monitoring and Reporting Program No. 98-810 prescribes a program for monitoring the clean-up and migration of the pollutant plume. Trichloroethylene (TCE) is the primary groundwater pollutant. The Discharger proposes to continue to discharge treated groundwater from the air-stripper system and the two GAC groundwater treatment systems. In a 25 April 2002 letter, the Discharger requested that WDRs Order Nos. 94-166 and 95-109 be combined into one order. |
