Rule 17.50.503 - WASTE GROUPS(1) Solid wastes are grouped based on physical and chemical characteristics which determine the degree of care required in handling and disposal and the potential of the wastes for causing environmental degradation or public health hazards. Solid wastes are categorized into three groups: (a) Group II wastes include decomposable wastes and mixed solid wastes containing decomposable material but exclude regulated hazardous wastes. Examples include, but are not limited to, the following: (i) municipal and household solid wastes such as garbage and putrescible organic materials, paper, cardboard, cloth, glass, metal, plastics, street sweepings, yard and garden wastes, digested sewage treatment sludges, water treatment sludges, ashes, dead animals, offal, discarded appliances, abandoned automobiles, and hospital and medical facility wastes, provided that infectious wastes have been rendered non-infectious to prevent the danger of disease; and(ii) commercial and industrial solid wastes such as packaging materials, liquid or solid industrial process wastes that are chemically or biologically decomposable, contaminated soils, crop residues, manure, chemical fertilizers, and emptied pesticide containers that have been triple rinsed or processed by methods approved by the department.(b) Group III wastes include wood wastes and non-water soluble solids. These wastes are characterized by their general inert nature and low potential for adverse environmental impacts. Examples include, but are not limited to, the following: (i) inert solid waste such as unpainted brick, dirt, rock, and concrete;(ii) clean, untreated, unglued wood materials, brush, unpainted or untreated lumber, and vehicle tires; and(iii) industrial mineral wastes which are essentially inert and non-water soluble and do not contain hazardous waste constituents.(c) Group IV wastes include construction and demolition wastes, and asphalt, except regulated hazardous wastes.(2) Clean fill is not regulated under this subchapter.Mont.
