The construction was done under <br />my supervision and to the best of my knowledge all work was performed in <br />accordance with the approved plan. <br />Compaction of the fill material continued until the unit dry weight of the <br />fill reached a value not less than 90% of the maximum unit dry weight attained <br />in a laboratory compaction test performed under the specifications of ASTM <br />D 698, Standard Proctor. The field compaction was monitored on an ongoing <br />basis. Corrective action was taken if tests did not show compliance with <br />specifications. The field density test reports are attached and are part <br />of this certification. <br />A compiete as-built survey of the refuse pile is not considered necessary. <br />The grades and slopes of the pile were checked continually during construction <br />to maintain the final contours shown in the approved plan. <br />0c~p^RFC/Sle <br />Fo~pe,e..~,~,~,~ ~ <br />F~ <br />James E.
