Sec. 16.
(a) Cover materials applied as required by section 14(f) of this rule for intermediate cover and 329 IAC 10-22 for final cover must be continuously maintained, including application and compaction of additional cover as needed to maintain required depth.(b) All MSWLFs must be graded to promote surface water drainage and to prevent the ponding of water on previously filled areas.(c) Vegetation must be cleared only as necessary.(d) Final cover must be vegetated as follows: (1) A grass or a diverse, effective, and permanent vegetative cover of the same seasonal variety that supports the approved post-closure land use must be established and maintained continuously on any portion of the MSWLF that has received final cover under 329 IAC 10-22, except where other provisions for land use have been approved by the commissioner.(2) No trees, woody shrubs, or deep rooted plants may be planted or allowed to grow on the vegetated final cover unless approved by the commissioner based on a demonstration that the roots will not penetrate the final cover cap.(e) Anchored mulch or erosion control blankets or both must be applied on all permanent seeding applications to control erosion, promote germination of seeds, and increase the moisture retention of the soil.(f) During those times of the year when adequate vegetation to control erosion cannot be established, anchored mulch, or a suitable alternative, must be applied to achieve an effective erosion control layer.(g) Vegetation or anchored mulch or both must be maintained and reapplied as necessary to sustain an effective erosion control layer.(h) Rills and gullies deeper than nine (9) inches that have formed in areas with intermediate or final cover must be filled, graded, reseeded, and mulched or otherwise stabilized.(i) Vegetation on closed portions of the MSWLF must be mowed as necessary.Solid Waste Management Board; 329 IAC 10-20-16; filed Mar 14, 1996, 5:00 p.m.: 19 IR 1850; filed Aug 2, 1999, 11:50 a.m.: 22 IR 3831; readopted filed Jan 10, 2001, 3:25 p.m.: 24 IR 1535
