DISP NON METALS -
The summation of a group of the methods that can be used to dispose of a metal or non-metal chemical off-site. The methods are:

      M10 Storage Only
      M63 Surface Impoundment
      M64 Other Landfills
      M65 RCRA Subtitle C Landfills
      M66 RCRA Subtitle C Surface Impoundment
      M67 Other Surface Impoundment
      M71 Underground Injection
      M72 Landfills/Disposal Surface Impoundment
      M73 Land Treatment
      M79 Other Land Disposal
      M81 Underground Injection to Class I Wells
      M82 Underground Injection to Class II-V Wells
      M90 Other Off-site Management
      M94 Transfers to Waste Broker for Disposal
      M99 Unknown

      DISP NON METALS = (M10 + M63 + M64 + M65 + M66 + M67 + M71 + M72 + M73 + M79 + M81 + M82 + M90 + M94 + M99)

DISP METALS -
The summation of a group of methods that can ONLY be used to dispose of metals off-site. The methods are:

      M40 Solidification/Stabilization (**)
      M41 Solidification/Stabilization
      M61 Wastewater Treatment (Excluding POTWs) (**)
      M62 Wastewater Treatment (Excluding POTWs)

      ** - Chemical must be a Type 1 Metal/Metal Compound or Vanadium (except when contained in Alloy)

      DISP METALS = (M40** + M41 + M61** + M62)
