Criteria and Characteristics of Hazardous Waste (D-List)
| Ignitability (D001) |
A solid waste that meets any of the following criteria:
- A liquid that has a flash point of less than 140o F as determined by a Pensky-Martens closed cup tester using ASTM method D-93-70 or D-93-80;
- A solid, under standard temperature and pressure, that can cause fire through friction, absorption of moisture, or spontaneous chemical changes and burn vigorously and persistently that it creates a hazard;
- An ignitable compressed gas as defined by the Department of Transportation in 49 CFR 173.300; or,
- An oxidizer as defined by the Department of Transportation in 49 CFR 173.151.
|
| Corrosivity (D002) |
A solid waste that meets any of the following criteria:
- An aqueous liquid that has a pH of 2 or less or 12.5 or more; or,
- A liquid that corrodes steel at a rate of 6.35 mm or more per year as determined by the National Association of Corrosion Engineers
|
| Reactivity (D003) |
A solid waste that meets any of the following criteria:
- Instability and readiness to under go violent change;
- Violent reactions when mixed with water;
- Formation of potentially explosive mixtures when mixed with water;
- Generation of toxic fumes in quantities sufficient to present a danger to human health or the environment when mixed with water;
- Cyanide or sulfide waste which generate toxic fumes when exposed to acidic conditions;
- Ease of detonation or explosive reaction when exposed to pressure or heat;
- Ease of detonation or explosive decomposition or reaction at standard temperature and pressure; or,
- Defined as a forbidden explosive by the Department of Transportation.
|
| Toxicity (D004-D043) |
A solid waste whose extract under the test procedure specified under 40CFR Part 261.24 contains one or more constituents at concentrations greater than those specified in the Maximum Concentration of Contaminants for the Toxicity Characteristic Table: |
