(a) comply with the applicable requirements of Section R315-302-2; and

(b) remove the solid waste from the pile at closure to another permitted facility.

(2) Requirements for solid waste likely to produce leachate.

(a) Waste piles shall be placed upon a surface such as sealed concrete, asphalt, clay, or an artificial liner underlying the pile to prevent subsurface soil and potential groundwater contamination and to allow collection of run-off and leachate. The liner shall be designed of sufficient thickness and strength to withstand stresses imposed by pile handling vehicles and the pile itself.

(b) A run-off collection and treatment system shall be designed, installed, and maintained to collect and treat a 25-year storm event.

(c) Waste piles having a capacity of greater than 10,000 cubic yards shall have either:

(i) a groundwater monitoring system that complies with Rule R315-308; or

(ii) a leachate detection, collection, and treatment system.

(iii) For Subsection R315-314-2(2), capacity refers to the total capacity of the leachate generating piles at one facility, for example, two, 5,000 cubic yard piles will subject the facility to the requirements of Subsection R315-314-2(2).

(d) A run-on prevention system shall be designed and maintained to divert the maximum flow from a 25-year storm event.

(e) The director may require that the entire base or liner shall be inspected for wear and integrity and repaired or replaced by removing stored wastes or otherwise providing inspection access to the base or liner; the request shall be in writing and cite the reasons including valid groundwater monitoring or leachate detection data leading to request an inspection, repair, or replacement.

(f) Post-closure requirements.

(i) Within 30 days of closure, a facility shall:

(A) remove any piles, windrows, and any other material on the facility's property;

(B) remove or revegetate compacted material that may be left on the land;

(C) drain ponds or leachate collection system, if any, backfill, and assure removed contents are properly disposed;

(D) cover if necessary; and

(E) for any pile not meeting the requirements of Subsection R315-314-2(3) record with the county recorder as part of the record of title, a plat and statement of fact that the property has been used for a waste pile.

(ii) Unless the facility owner or operator demonstrates that the requirements of Section R315-301-6 are met and receives a waiver from the director, post-closure care and monitoring shall be for five years and shall consist of:

(A) the maintenance of any monitoring equipment and sampling and testing schedules as required by the director; and

(B) inspection and maintenance of any cover material.

(3) The length of time that solid waste may be stored in piles may not exceed one year unless the director determines that the solid waste may be stored in piles for a longer time period without becoming a threat to human health or the environment.

(4) The director or an authorized representative may enter and inspect a site where waste is stored in piles as specified in Subsection R315-302-2(5)(b).
