April 4, 2012 <br /> improve recharge to the local aquifer and is also designed to create a <br /> hydraulic barrier to inhibit further northward migration of the groundwater <br /> plume. The RWQCB letter to Forward dated March 11, 2002 agreed to <br /> allow for their recharge remedy (Alternative 11) to go forward without <br /> Alternative 3 (extended pumping) while quarterly monitoring at the <br /> groundwater wells occurs. If the groundwater VOC concentrations do not <br /> attenuate at a rate that is acceptable to the RWQCB then the Board will <br /> require that Alternative 3, or some variant on Alternative 3, be <br /> implemented. The recent (AEE, 2002a) addendum to the corrective action <br /> proposed procedures to analyze the hydrochemical trends and trigger <br /> concentrations at which additional extraction wells would be considered. <br /> (Atkinson, 2002). <br /> Current Status: Forward complies with the RWQCB groundwater <br /> monitoring and corrective action requirements. <br /> i. 51 (F.9) <br /> Identified in EIR: <br /> Replacement wells (as well as additional wells north of the Austin Road <br /> Landfill to better define the leading edge of the plume) shall be installed to <br /> mitigate against the loss of old wells as presented in the JTD currently <br /> under review by the RWQCB. The RWQCB must approve the JTD's <br /> plans for the number and location of the new wells as part of their approval <br /> process, which is separate from the EIR approval process. <br /> Current Status: The RWQCB has approved Forward's JTD. Forward <br /> complies with the RWQCB groundwater monitoring and corrective action <br /> requirements. <br /> J. 52 Austin 1994 (K3.c), Austin 2000(K3.c) <br /> The timing of the pumped discharge from the detention pond must not <br /> occur with the peak flow rate of Little John's Creek as this would impact <br /> downstream locations by increasing the flood hazard. Telemetry, which <br /> monitors the flow in the creek to determine the peak, should be provided. <br /> This information should then be used to coordinate the start up of the <br /> pumps. <br /> Current Status: Forward complies with the stormwater control <br /> requirements detailed in the JTD. Both this Use Permit and the RWQCB <br /> permit have referenced the JTD for stormwater control measures required at <br /> the site. <br /> Page 29 <br />
