Section 1.13 - Massachusetts Total Hazard Classification System
Current through Register 1531, September 27, 2024
(1) The data to be derived from a total hazard classification system for Massachusetts shall be used in tracking waste generation and in the siting, design, performance assessment, licensing, closure, monitoring, and possible remediation of future facilities. They may also be used to make assessments and decisions on other waste management needs, such as the need for additional waste minimization and other waste treatment steps and for negotiation of agreements, contracts, or interstate compacts with other states.
(2) The classification system shall consist of:
(3) The Massachusetts LLRW disposal classification system shall be as set forth in Table 1.13A.
TABLE 1.13A
Classification for Licensed LLRW Disposal | |
Disposal Class | Description |
HVLA | High Volume, Low Activity Waste. |
AU | Class A unstable LLRW. |
AS | Class A stable LLRW. |
B | Class B LLRW per NRC. |
C | Class C LLRW per NRC. |
GTCC | Greater-than-Class-C - not suited for near-surface disposal.* |
AU-H | Class A unstable LLRW with treated RCRA/DEP hazardous waste components. |
AS-H | Class A stable LLRW with treated RCRA/DEP hazardous waste components. |
B-H | Class B LLRW with treated RCRA/DEP hazardous waste components. |
C-H | Class C LLRW with treated RCRA/DEP hazardous waste components. |
GTCC-H | Greater than Class C LLRW with treated RCRA/DEP hazardous waste components -not suitable for near-surface disposal.* |
* GTCC waste is the responsibility of the feder classified here for tracking purposes only. al government and is not LLRW. GTCC is |
