<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br /> <br /> <br />u <br />~l <br /> <br />The technical approach for this project is <br />based on conditions listed in the letter dated <br />January 17, 1996, from the Division and <br />conversations with Mr. James Stevens with <br />the Division. Presented below, in bold, are <br />the 16 conditions followed by Greystone's <br />proposed work plan to complete each <br />condition. <br />Condition 1: The County will supply a map <br />of the permit and immediately surrounding <br />azea at a scale of 1 inch equals 500 feet on <br />which the locations of the four proposed <br />monitoring wells will be indicated. This <br />map will be provided to the Division by <br />Mazch 1, 1996. <br />Work Plan: Greystone will prepaze a site <br />map at a scale of 1 inch equals 500 feet. <br />The site map will include property <br />boundaries, monitor wells, landfill pit, <br />utilities, and improvements on the site. In <br />addition, adjacent property land use will be <br />indicated. <br />Condition 2: The County will position the <br />proposed monitoring wells so that at least <br />one of them is hydrologically upgradient <br />from the pit, outside the area of influence of <br />the pit and can be expected to represent <br />background groundwater quality. At least <br />one of the wells must also by hydrologically <br />downgradient from the pit in a position to <br />intercept any evidence of possible <br />contamination of local groundwater by the <br />pit and to serve as a Point of Compliance as <br />defined in the Construction Materials Rules <br />and Regulations. <br />Work Plan: On January 26, 1996, <br />Greystone discussed locating the four <br />monitor wells with Mr. Stevens of the <br />Division. Mr. Stevens stated that one well is <br />to be installed upgradient from the pit to <br />determine background water quality, and at <br />Costilla\1-96 <br />2-1 <br />
