Additional measures which EFCI utilizes to control surface runoff from the refuse <br />disposal facility include: <br />- Temporary ditches within the working areas. <br />- Contour furrows on reclaimed surfaces where appropriate. <br />- Maintenance of a 15 foot buffer zone between active refuse placement <br />operations and topsoil removal/placement limits. <br />- Establishment of positive drainage from the top and sideslopes of the refuse <br />stockpile. <br />- Revegetation or riprap placement for all drainage control structures. <br />- Replacement of topsoil and revegetation as soon as practical after <br />completion of refuse placement and surface grading. <br />- Post-reclamation monitoring and maintenance. <br />4.10.4 CONSTRUCTION REQUIREMENTS <br />As described in Section 2.05.3, Operation Plan -Permit Area, EFCI utilizes refuse <br />placement practices and construction techniques in accordance with the provisions <br />of this section and as detailed in Exhibit 18, Geotechnical Investigations. <br />Placement and construction practices have been designed such that long term <br />stability of the refuse pile will be maintained with a minimum static factor of safety <br />of 1.5. Refuse materials will be placed and compacted in horizontal lifts no more <br />than two (2) feet in thickness. Coarse and fine refuse lifts will be compacted to a <br />minimum dry density of 52 pcf. All refuse materials are placed and compacted in <br />such a manner to minimize the flow of air through the pile, ensure stability of the <br />pile, and maintain the required factor of safety. <br /> <br />4.10 - 5 Revised 5/22/97 <br />Technical Revision No. 27 <br />
