  • Crushed asphalt, but only if the product is used:
    • As fill material for a building pad or parking area;
    • As road base beneath a parking area or road;
    • As pavement on a building pad, parking area, or road; or,
    • As a material to construct a containment berm for a tank farm

  • The waste may not cause a public nuisance, environmental problem, or a threat to public health, safety, or welfare.
