E <br />E <br />E <br />A postclosure maintenance program will be prepared according to CWMB <br />requirements and implemented at the landfill upon closure to verify that <br />containment and monitoring facilities retain their integrity. The program will <br />include provisions for the routine evaluation of surface drainage control facilities, <br />final vegetated soil cover areas, ground -water monitoring facilities, and access <br />roads. Cracks in the final cover will be sealed. Any erosion damage caused by <br />extremely heavy rainfall will be repaired. Temporary berms, ditches, and straw <br />mulch will be used to prevent further erosion damage to soil cover areas until <br />weather conditions permit replacing eroded soil and reseeding. Such actions <br />should preclude problems associated with leachate generation due to infiltration <br />of surface water, gas venting through the cover at unacceptable locations, and <br />insects and rodents that could be attracted by exposed refuse after closure. <br />The ground -water, leachate, and landfill gas monitoring programs for the site will <br />continue in cooperation with the RWOCB and the CWMB. <br />PJ9 9390218A.00W 67 Rev. 0 July 20, 198S <br />
