Pyrophoric Solid. “Pyrophoric solid” means solid material, other than one classed as an explosive, which under normal conditions is liable to cause fires through friction or retained heat from manufacturing or processing, or which can be ignited readily and when ignited burns so vigorously and persistently as to create a serious transportation, handling, or disposal hazard. “Pyrophoric solid” includes spontaneously combustible and water-reactive material. “Radioactive hazardous substance (RHS)” means a radioactive hazardous substance as defined in COMAR 26.15.02.02. Radioactive hazardous substance is synonymous with low-level nuclear waste and low-level radioactive waste as defined in Environment Article, §7-201, Annotated Code of Maryland, and §2 of the National Low-Level Radioactive Waste Policy Amendments Act of 1985, respectively. “Radioactive hazardous substances generator (RHSG)” means a person that produces a radioactive hazardous substance. “RCIR” means a document entitled “Maryland State Department of the Environment Regulations for Control of Ionizing Radiation (1985)” which is incorporated by reference in COMAR 26.12.01.01. “Regional disposal facility” means a facility within a compact state which has been approved by the Appalachian States Low-Level Radioactive Waste Commission for the disposal of low-level radioactive waste. “RHS disposal” means the isolation of RHS from the biosphere inhabited by man and containing his food chains by emplacement in an RHS land disposal facility. “RHS facility” means all continuous land and structures, other appurtenances, and improvements on the land, used for treating, storing, or disposing of RHS. A facility may consist of several treatment, storage, or disposal operational units. “RHS manifest” means the national uniform low-level radioactive waste manifest appropriately completed and signed by the RHS generator which contains the information required by COMAR 26.15.03.05 and by 10 CFR §20.2006. “RHS treatment” means a method, technique, or process including neutralization that is designed to change the physical, chemical, radioactive, or biological characteristics or composition of a radioactive hazardous substance (RHS) so as to render the RHS nonradioactive or nonhazardous, safe for transport, or reduced in volume. “Secretary” means the Secretary of the Environment, or the Secretary's designee. “Site closure and stabilization” means action that is taken upon completion of operations that prepares the disposal site for custodial care and assures that the disposal site will remain stable and not need ongoing active maintenance. “Source” means a person who generates, transports, treats, stores, or disposes of RHS. “Stability” means structural stability.
