1. (a) Stockpiles of waste shall be positioned within a footprint identified on the facility site plan.

2. (b) If a stockpile will be open to precipitation, the footprint of the stockpile shall be:

   1. (1) Underlain by an asphalt, concrete, or packed soil surface; and
   2. (2) Graded to prohibit precipitation and surface drainage from surrounding areas from draining through or collecting in the stockpile area.
3. (c) A waste stockpile shall be located, sized, and configured in accordance with (d) below and as required by local fire authorities in order to assure that available local firefighting equipment and resources will be able to effectively respond to a fire at the facility.

4. (d) At a minimum, a C/S/T facility shall be designed to:

   1. (1) Provide access to all waste stockpiles for fire control purposes, including the placement and maintenance of fire lanes between and around all stockpiles of combustible waste;
   2. (2) Limit the height of the stockpiles to a height compatible with local fire fighting equipment response capabilities; and
   3. (3) Provide a water supply within a distance and in a quantity sufficient for local fire fighting needs.
5. (e) A stockpile shall be sized and configured to be physically stable against slides, collapse, or other conditions that might result in personal injury or destruction of property.

7. (g) A stockpile of a waste listed in Env-Sw 900 shall conform to the applicable stockpiling requirements specified in Env-Sw 900, if any.
8. (h) If a waste exhibits a characteristic which has the potential to cause groundwater or surface water contamination when placed in contact with the ground surface, the waste shall be stockpiled in a manner as to prevent the contamination by means of a leachate collection system or functionally equivalent control system.
9. (i) If a waste exhibits a characteristic which has the potential to cause air pollution or a respiratory hazard, the waste shall be stockpiled in a manner as to prevent the air pollution and respiratory hazard in conformance with state and federal regulations for the control of air pollution, including RSA 125-C.
10. (j) If a waste has the potential to erode or spread when stockpiled, the waste shall be stored in either a container or a building or stockpiled and contained in a manner so as to prevent spread of the waste such as by placement of barriers on 3 sides.
