A. At final closure of the landfill or upon closure of any cell, the owner or operator must cover the landfill or cell with a final cover designed and constructed to:

1. provide long-term minimization of migration of liquids through the closed landfill;

2. function with minimum maintenance;

3. promote drainage and minimize erosion or abrasion of the cover;

4. accommodate settling and subsidence so that the cover's integrity is maintained; and

5. have a permeability less than or equal to the permeability of any bottom liner system or natural subsoils present.

2. maintain and monitor the leak detection system in accordance with LAC 33:V.2503.L.4.d, 2503.L.5, and 2507.D, where such a system is present between double liner systems and comply with all other applicable leak detection system requirements of LAC 33:V.Subpart 1;

3. continue to operate the leachate collection and removal system until leachate is no longer detected;

4. maintain and monitor the groundwater monitoring system and comply with all other applicable requirements of LAC 33:V.Chapter 33;

5. prevent run-on and run-off from eroding or otherwise damaging the final cover; and
