R315-314-2. General Requirements

  (1) Each owner and operator shall:

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

  (b) remove all 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 ground water 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 ground water monitoring system that complies with Rule R315-308; or

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

  (iii) For purposes of this subsection, capacity refers to the total capacity of all leachate-generating piles at one facility, e.g., two, 5,000 cubic yard piles will subject the facility to the requirements of this subsection.

  (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 ground water monitoring or leachate detection data leading to request such an inspection, repair or replacement.

  (3) The length of time that solid waste may be stored in piles shall not exceed 1 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).
