I <br /> j <br /> 14 November 2014 <br /> AGE Project No , 07- 1529 <br /> Page 3 of 6 <br /> According to the General Order, a contingency plan is required to be implemented to <br /> correct unacceptable water quality effects from ISCO applications. The contingency <br /> plans should describe in detail actions that will be taken to bring any constituents <br /> exceeding WQOs and limitations from the ISCO injections back into compliance with the <br /> requirements of the General Order. <br /> In addition to cessation of injections , if unacceptable conditions are observed during <br /> progress/compliance monitoring , all monitoring wells showing negative effects will be <br /> pumped in bulk until WQO' s are deemed acceptable by the RWQCB . Additionally future <br /> injection events will be suspended until further comment and approval by the RWQCB . <br /> As part of the contingency plan , monitoring frequency will be altered from quarterly to <br /> monthly schedule to verify that bulk pumping has addressed the negative effects of any <br /> injections. <br /> CVRWQCB Comment 4: According to Site reports, other than well VEW-2 there does <br /> not appear to be any downgradient monitoring wells screened across the water table <br /> interface. Central Valley Water Board staff recommends installing property screened <br /> monitoring wells to monitor potential contaminant migration in the shallow water bearing <br /> zone downgradient of the site. <br /> In accordance with the above recommendations , AGE recommends the installation of <br /> two additional shallow screened wells . The locations of the wells are illustrated in Figure <br /> 2 . Installations procedures are provided below . <br /> WELL INSTALLATION WORK PLAN <br /> Based on Water Board requirements to obtain a waste discharge permit for ISCO <br /> injections at the above referenced site , AGE has prepared this work plan detailing the <br /> installation of two (2) ISCO injection wells , two (2) shallow groundwater monitoring wells <br /> one (1 ) deep groundwater monitoring well . Procedures for the installations are provided <br /> below. <br /> SCOPE OF WORK <br /> The scope of the work includes the drilling and installation of two (2) deep-screened <br /> monitoring wells , one deep monitoring well and two (2) shallow groundwater monitoring <br /> wells . The scope of work will include the following tasks : <br /> • Permitting and pre-field work activities ; <br /> • Pilot drilling ; <br /> Advanced GeoEnvironmental, Inc <br />
