Section 1.13 - Massachusetts Total Hazard Classification System
(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:
(a) A survey, or data acquisition tool, to allow detailed characterization of each waste stream;
(b) An inventory, or data compilation tool;
(c) A codification system to allow categorization, classification, and data sorting;
(d) A codification system to allow identification, management, and disposal consistent with other federal and state regulations (e.g., NRC, EPA, DEP);
(e) A data manipulation and analytic tool to process and compile data by any characteristics of interest and for any need; and
(f) A classification and tracking (manifest) system to allow operation, monitoring, and remediation, if necessary, at potential storage, treatment, or disposal facilities.
(3) The Massachusetts LLRW disposal classification system shall be as set forth in Table 1.13A.
