310 CMR, § 30.130
310 CMR 30.131 through 30.136 contain four lists of hazardous wastes. The first is a list of waste from non-specific sources. Such wastes may be generated as a part of a number of different industrial operations. Any residue or contaminated soil, water, or other debris resulting from the clean up of a spill, into or on any land or water, of any hazardous waste on this list shall carry the EPA Hazardous Waste Number of the released hazardous waste unless another hazardous waste number is designated within 310 CMR 30.131 (see, e.g., F039).
The second is a list of hazardous wastes produced by specific industries. Any residue or contaminated soil, water, or other debris resulting from the clean up of a spill, into or on any land or water, of any hazardous waste on this list shall carry the EPA Hazardous Waste Number of the released hazardous waste.
The third is a list of commercial chemical products which, if discarded or intended to be discarded in pure or off-specification form, constitute hazardous waste.
The fourth is a list of acutely hazardous wastes.
The Department will indicate the basis for listing the classes or types of wastes listed in 310 CMR 30.131 through 30.136 which have EPA Hazardous Waste Numbers by employing one or more of the following Hazard Codes:
| Ignitable Waste .................................................. | (I) |
| Corrosive Waste .................................................. | (C) |
| Reactive Waste ................................................... | (R) |
| Toxicity Characteristic Waste .......................... | (E) |
| Acutely Hazardous Waste ..................................... | (H) |
| Toxic Waste .......................................................... | (T) |
The absence of a letter code in 310 CMR 30.133 indicates that the compound is listed for toxicity. The absence of a letter code in 310 CMR 30.136 indicates that the compound is listed for acute toxicity. Appendix VII of 40 CFR 261, which is adopted at 310 CMR 30.162, identifies the constituent which caused a waste to be listed for toxicity in 310 CMR 30.131 and 310 CMR 30.132.
A waste is a hazardous waste if it is listed in 310 CMR 30.131 through 30.136, unless it has been excluded pursuant to 310 CMR 30.142. A hazardous waste listed in 310 CMR 30.131 through 30.136 has the Hazardous Waste Number specified therein.
In addition, the following Hazardous Waste Numbers shall be used as set forth below:
| Hazardous Waste No. | Substance |
| MA00 | Hazardous waste designated as such pursuant to 310 CMR 30.144. The manifest shall include (1) a description of the most hazardous constituent of the waste, and (2) a reference to the date when the Department designated the waste as hazardous, and, (3) reference to the office of the Department which designated the waste as hazardous. For example: "Alizarin mixture, 3/7/85 NE". |
| MA95 | Universal waste shipped on a hazardous waste manifest by a licensed hazardous waste transporter. |
| MA97 | Class A regulated recyclable material (including, but not limited to, specification used oil fuel) that is shipped using a hazardous waste manifest. |
| MA98 | Off-specification used oil fuel that is shipped using a hazardous waste manifest. |
| MA99 | Not hazardous waste. This designation is to be used only for material that is not hazardous waste and that is shipped using a hazardous waste manifest. |
