1. (a) The requirements of this section do not apply to a waste management area where inert waste is disposed of within the boundaries of a MSWLF.
2. (b) Liners are not required at an inert waste monofill.

3. (c) If a groundwater monitoring system is required at an inert waste monofill under 18 AAC 60.820, detection monitoring under 18 AAC 60.840 and 18 AAC 60.850 during the active life of the monofill will be required only if the department

   1. (1) determines that non-inert waste is or has been present at the site;
   2. (2) detects evidence of a spill or groundwater contamination; or
   3. (3) finds unexplained contamination in nearby wells.
4. (d) The owner or operator of an inert waste monofill who accepts combustible inert waste shall maintain fire control equipment and make it available to extinguish any fires that start.
5. (e) The owner or operator of an inert waste monofill shall construct a final cover of soil material at least 24 inches thick, graded to promote drainage without erosion, and shall revegetate it. The department will approve an alternate final cover design if the applicant demonstrates that the alternate design will protect public health, safety, and welfare, and the environment. After completion of the final cover on a monofill with a groundwater monitoring system, the owner or operator shall conduct detection monitoring at the frequency required by 18 AAC 60.825(i).
