WORK PLAN FOR <br /> THE INSTALLATION OF AN <br /> ADDITIONAL GROUND WATER MONITORING WELL <br /> OVERHEAD DOOR CORPORATION <br /> 1220 E. VICTOR ROAD <br /> LODI , CALIFORNIA <br /> 1 . 0 INTRODUCTION <br /> The Dallas Corporation, Lodi Overhead Door facility, is located <br /> at 1220 E. Victor Road, Lodi, California, also referred to as <br /> the NW 1/4 , SE 1/4, of Section 6, T3N, R7E, MDB&M. The site <br /> consists of approximately 9 acres and is situated as indicated <br /> on Figure 1 . <br /> A Hydrogeologic Assessment Report (HAR) and Final Closure Plan <br /> for the Lodi Overhead Door facility' s former surface empoundment <br /> were prepared by J.H. Kleinfelder & Associates and submitted for <br /> review to the California Regional Water Quality Control Board <br /> (RWQCB) . In response to the RWQCB review comments, Mr. James <br /> Harvey (Dallas Corporation) submitted a work plan and time <br /> schedule for an amendment to the HAR which included the <br /> installation of a deep ground water monitoring well (estimated <br /> 125 foot depth) to be located adjacent to existing upgradient <br /> monitoring well (MW #4 ) and an additional shallow ground water <br /> monitoring well ( estimated 65 foot depth) to be located <br /> down-gradient of the former surface impoundment site. The deep <br /> ground water monitoring well was installed by BSK & Associates <br /> for BSK Remediation in December 1988 . <br /> The purpose of the current investigation is to install the <br /> shallow down-gradient ground water monitoring well. Recent water <br /> level measurements indicate that the depth to ground water ranges <br /> from 47 to 51 feet below the ground surface across the site. <br /> Based on this information, the proposed monitoring well would be <br /> set at an approximate depth of 75 feet. <br /> 2. 0 PROPOSED WORK PLAN <br /> The current scope of work for this investigation includes <br /> drilling one ( 1 ) exploratory boring extending to an approximate <br /> depth of 70 feet below the ground surface using an eight ( 8 ) <br /> inch, nominal diameter, continuous flight hollow stem auger. The <br /> proposed boring would be located adjacent to the southwest corner <br /> of Building 4 ( see Figure 2 ) and would be converted to an open <br /> standpipe piezometer monitoring well ( identified as Monitoring <br /> Well #5 ) . <br /> COPY BSI <br />
