The final step in constructing the final cover was to vegetate the <br /> site. This was accomplished by hydroseeding the vegetative layer. <br /> The hydroseeding process was made up of five steps. The first step <br /> was to harrow the top of the vegetative layer surface using a farm <br /> implement drug by a tractor. The second step consisted of spraying <br /> a slurry mixture of seed, fertilizer, and mulch over the surface. <br /> The third step involved blowing straw over the slurry mixture. The <br /> fourth step entailed the incorporation of straw into the surface by <br /> means of a studded roller drug behind a vehicle. The fifth and <br /> final step consisted of spraying a slurry mixture of mulch and <br /> emulsifier over the incorporated straw in order to bind the straw <br /> to the surface. It should be noted that steps one and four were <br /> not performed on side slope areas. <br /> CONCLUSION <br /> This report summarizes the construction methods used in <br /> constructing the final cover for the Harney Lane Sanitary Landfill. <br /> This report serves to certify the foundation and vegetative layer <br /> portions of the final cover. Additionally, this report includes <br /> the Kleinfelder report certifying the clay barrier layer portion of <br /> the final cover as Appendix A. San Joaquin County will continue to <br /> perform postclosure maintenance as outlined in the most recent <br /> Postclosure Maintenance Plan for the thirty year post-closure <br /> maintenance period. <br /> 13 <br />
