SUB-PROBLEMS INCLUDING LEADING TO IMPAIRMENT AND BEST PRACTICES FOR HAZARDOUS WASTE LANDFILLS
There are restrictions on substances that can be put into the hazardous waste landfill. Under no condition would incompatible substances be put in the same area. This could result in explosions and chemical interactions which would create highly toxic byproducts that could destroy the system and become water pollutants or air pollutants. There are specific restrictions on: dioxin-containing wastes; soils that have the toxic characteristics of metals and PCBs; chlorinated aliphatic wastes; toxic metal wastes; petroleum-refining materials; inorganic chemicals; ignitable and corrosive wastes; and newly identified organic wastes with considerable toxicity.
Hazardous waste must not be put into any land treatment facility unless the waste can be made less hazardous or non-hazardous by degradation, transformation, or immobilization in the soil. The hazardous waste landfill must be designed, constructed, operated, and maintained in such a manner that there cannot be any flow of any type out of the given area. Water volume due to storms must be kept totally away from the disposal area. Collection and holding facilities of water must be such that it can be treated if necessary and discharged after the storm is over into other areas which are not being used for hazardous waste disposal.
