R 299.4103 Definitions; F to L.

Rule 103. As used in these rules: (a) "Facility" means a solid waste disposal area as defined in R 299.4106a. (b) "Floodplain" means the lowland and relatively flat areas which adjoin inland and coastal waters and which are inundated by the 100-year flood. The 100-year flood is a flood that has a 1% or greater chance of recurring in any given year or a flood of a magnitude equaled or exceeded once in 100 years on the average over a significantly long period. (c) "Floodway" means the channel of a watercourse and those portions of the floodplain adjoining the channel that are reasonably required to transmit the 100-year flood. (d) "Food processing wastes" means solid wastes that result from processing fruits and vegetables for preservation by freezing, drying, or canning. (e) "General public" means private citizens who are unlikely to incur a financial gain or loss greater than that of an average homeowner, taxpayer, or consumer as a result of any action taken by a planning committee. (f) "Geologist" or "qualified groundwater scientist" means a scientist or engineer who has received a baccalaureate or postgraduate degree in the natural sciences or engineering and who has sufficient training and experience in groundwater hydrology and related fields, as demonstrated by state registration, professional certifications, or completion of accredited university programs, to make sound professional judgments regarding groundwater monitoring, contaminant fate and transport, and corrective action. (g) "Geotextile" means any permeable material that is used with foundation, soil, rock, earth, or any other geotechnical engineering-related material as an integral part of a man-made structure or system. (h) "Groundwater" means water below the land surface in a zone of saturation. (i) "Groundwater level" means the surface of the groundwater in the uppermost aquifer in unconfined conditions or the bottom of the confining bed in confined conditions. (j) "Hazardous substance" means a hazardous substance as defined in part 201 of the act. (k) "Household waste" means any solid waste that is derived from single households, but does not include any of the following: (i) Commercial waste. (ii) Industrial waste. (iii) Construction and demolition waste. (l) "Hydraulic conductivity" or "permeability" means the rate of flow of a liquid under a differential pressure through a material. The hydraulic conductivity of cohesive soils shall be determined using the methods specified in R 299.4920. (m) "Incinerator" means a device which is specifically designed for the destruction, by burning, of garbage or other combustible refuse or waste material, or both, and in which the products of combustion are emitted into the outer air by passing through a stack or chimney. For purposes of the act and these rules, the following devices are not incinerators: (i) A thermal treatment unit that is designed solely for the purpose of destroying contaminants in soil. (ii) Boilers, industrial furnaces, or power plants that burn site-separated material, source-separated material, or industrial waste as fuel. (iii) A device that is used to incinerate medical waste and other waste from a facility that generates medical waste. (n) "Industrial waste" means solid waste which is generated by manufacturing or industrial processes or originates from an industrial site and which is not a hazardous waste regulated under part 111 of the act. (o) "Industrial waste landfill" means a landfill that is used for the disposal of industrial waste which has been characterized for hazard and which has been determined to be nonhazardous under part 111 of the act. An industrial waste landfill may accept industrial waste of different types and from different generators, but shall not accept hazardous waste generated by conditionally exempt small quantity generators, as defined under part 111 of the act. (p) "Landfill unit" means a discrete area of land which is permitted to receive waste for permanent disposal and which is not a waste pile. For purposes of these rules, the discrete area shall consist of all areas where waste is or will be contiguous, excluding any portion that has been closed under part 111 of the act. Contiguous portions may be separated by berms and may contain different liner or leachate collection designs and separate leachate collection systems, if waste in one portion is or will be in contact with waste in another portion. The boundaries of a landfill unit may be increased by lateral extensions consistent with the construction permit or plans approved by the department. A landfill unit may be any of the following: (i) A new unit. (ii) An existing unit. (iii) A preexisting unit. (iv) A closed unit. (q) "Lateral expansion" means a horizontal expansion of the solid waste boundary of a landfill beyond the limit established in a construction permit or engineering plans approved by the solid waste control agency before January 11, 1979. (r) "Lateral extension" means the extension of an existing unit within the solid waste boundary, but beyond that area constructed and licensed on October 9, 1993. (s) "Leachate" means liquid which has come in contact with, passed through, or emerged from, solid waste and which contains soluble, suspended, or miscible materials that are removed from the wastes. (t) "Lead acid battery" means a storage battery in which the electrodes are grids of lead oxides that change in composition during charging and discharging and in which the electrolyte is dilute sulfuric acid. (u) "Leak detection system" means the secondary collection system of an unmonitorable unit. The purpose of a leak detection system is to detect, collect, and remove leaks of hazardous substances at the earliest practicable time through all areas of the top liner likely to be exposed to waste or leachate during the active life and postclosure period. (v) "Lift" means a layer of placed material, including a layer of compacted clay in a landfill layer or cap, or a layer of waste in a sanitary landfill. (w) "Liquid waste" means any waste material that is determined to contain free liquids as defined by method 9095, the paint filter liquids test, as described in the publication entitled "Test Methods for Evaluating Solid Wastes, Physical-Chemical Methods" SW-846, which is adopted by reference in R 299.4133. For purposes of the act and these rules, liquid waste does not include industrial waste sludges that are disposed of at a location other than a type II landfill.
