| (25) Metropolitan Statistical Area--Any areas listed as metropolitan statistical areas in Office of Management and Budget Bulletin No. 05 - 02 entitled "Update of Statistical Area Definitions and Guidance on Their Uses" dated February 22, 2005 (available on the Web at http://www.whitehouse.gov/omb/bulletins/). (26) Modification or modified unit--An incineration unit you have changed on or after June 16, 2006, and that meets one of two criteria: (A) The cumulative cost of the changes over the life of the unit exceeds 50 percent of the original cost of building and installing the unit (not including the cost of land) updated to current costs (current dollars). For an other solid waste incineration (OSWI) unit, to determine what systems are within the boundary of the unit used to calculate these costs, see the definition of OSWI unit. (B) Any physical change in the OSWI unit or change in the method of operating it that increases the amount of any air pollutant emitted for which the Federal Clean Air Act, §129 or §111 has established standards. (27) Municipal solid waste--Refuse (and refuse-derived fuel) collected from the general public and from residential, commercial, institutional, and industrial sources consisting of paper, wood, yard wastes, food wastes, plastics, leather, rubber, and other combustible materials and non-combustible materials such as metal, glass, and rock, provided that: (A) The term does not include industrial process wastes or medical wastes that are segregated from such other wastes; and (B) an incineration unit shall not be considered to be combusting municipal solid waste for purposes of this division if it combusts a fuel feed stream, 30 percent or less of the weight of which is comprised, in aggregate, of municipal solid waste, as determined by 40 Code of Federal Regulations §60.2993(b). (28) Municipal waste combustion unit--For the purpose of this division, any setting or equipment that combusts municipal solid waste (as defined in this division) including, but not limited to, field-erected, modular, cyclonic burn barrel, and custom built incineration units (with or without energy recovery) operating with starved or excess air, boilers, furnaces, pyrolysis/combustion units, and air curtain incinerators (except those air curtain incinerators listed in 40 Code of Federal Regulations §60.2994(b)). (29) Other solid waste incineration (OSWI) unit--Either a very small municipal waste combustion unit or an institutional waste incineration unit, as defined in this division. Unit types listed in 40 Code of Federal Regulations §60.2993 as being excluded from the division are not OSWI units subject to this division. While not all OSWI units will include all of the following components, an OSWI unit includes, but is not limited to, the municipal or institutional solid waste feed system, grate system, flue gas system, waste heat recovery equipment, if any, and bottom ash system. The OSWI unit does not include air pollution control equipment or the stack. The OSWI unit boundary starts at the municipal or institutional waste hopper (if applicable) and extends through two areas: (A) The combustion unit flue gas system, which ends immediately after the last combustion chamber or after the waste heat recovery equipment, if any; and (B) The combustion unit bottom ash system, which ends at the truck loading station or similar equipment that transfers the ash to final disposal. The OSWI unit includes all ash handling systems connected to the bottom ash handling system. (30) Particulate matter--Total particulate matter emitted from other solid waste incineration units as measured by Method 5 or Method 29 of 40 Code of Federal Regulations Part 60, Appendix A. (31) Pathological waste--Waste material consisting of only human or animal remains, anatomical parts, and/or tissue, the bags/containers used to collect and transport the waste material, and animal bedding (if applicable). (32) Reconstruction--Rebuilding an incineration unit and meeting two criteria: (A) The reconstruction begins on or after June 16, 2006. (B) The cumulative cost of the construction over the life of the incineration unit exceeds 50 percent of the original cost of building and installing the unit (not including land) updated to current costs (current dollars). For an other solid waste incineration (OSWI) unit, to determine what systems are within the boundary of the unit used to calculate these costs, see the definition of OSWI unit. (33) Refuse-derived fuel--A type of municipal solid waste produced by processing municipal solid waste through shredding and size classification. This includes all classes of refuse-derived fuel including two fuels: (A) Low-density fluff refuse-derived fuel through densified refuse-derived fuel; and (B) Pelletized refuse-derived fuel. (34) Shutdown--The period of time after all waste has been combusted in the primary chamber. For continuous other solid waste incineration (OSWI), shutdown shall commence no less than 2 hours after the last charge to the incinerator. For intermittent OSWI, shutdown shall commence no less than 4 hours after the last charge to the incinerator. For batch OSWI, shutdown shall commence no less than 5 hours after the high-air phase of combustion has been completed. (35) Solid waste--Any garbage, refuse, sludge from a waste treatment plant, water supply treatment plant, or air pollution control facility and other discarded material, including solid, liquid, semisolid, or contained gaseous material resulting from industrial, commercial, mining, agricultural operations, and from community activities, but does not include solid or dissolved material in domestic sewage, or solid or dissolved materials in irrigation return flows or industrial discharges that are point sources subject to permits under the Federal Water Pollution Control Act, §402 as amended (33 United States Code (USC), §1342), or source, special nuclear, or byproduct material as defined by the Atomic Energy Act of 1954, as amended (42 USC, §2014). (36) Standard conditions--When referring to units of measure, a temperature of 68 degrees Fahrenheit (20 degrees Celsius) and a pressure of 1 atmosphere (101.3 kilopascals). (37) Startup period--The period of time between the activation of the system and the first charge to the other solid waste incineration (OSWI) unit. For batch OSWI, startup means the period of time between activation of the system and ignition of the waste. (38) Very small municipal waste combustion unit--Any municipal waste combustion unit that has the capacity to combust less than 35 tons per day of municipal solid waste or refuse-derived fuel, as determined by the calculations in §113.2356 of this title (relating to What equations must I use?). (39) Waste heat recovery--The process of recovering heat from the combustion flue gases outside of the combustion firebox by convective heat transfer only. (40) Wet scrubber--An add-on air pollution control device that utilizes an aqueous or alkaline scrubbing liquor to collect particulate matter (including nonvaporous metals and condensed organics) and/or to absorb and neutralize acid gases. (41) Wood waste--Untreated wood and untreated wood products, including tree stumps (whole or chipped), trees, tree limbs (whole or chipped), bark, sawdust, chips, scraps, slabs, millings, and shavings. Wood waste does not include: (A) Grass, grass clippings, bushes, shrubs, and clippings from bushes and shrubs from residential, commercial/retail, institutional, or industrial sources as part of maintaining yards or other private or public lands. (B) Construction, renovation, or demolition wastes. (C) Clean lumber. (D) Treated wood and treated wood products, including wood products that have been painted, pigment-stained, or pressure treated by compounds such as chromate copper arsenate, pentachlorophenol, and creosote, or manufactured wood products that contain adhesives or resins (e.g., plywood, particle board, flake board, and oriented strand board). (42) Yard waste--Grass, grass clippings, bushes, shrubs, and clippings from bushes and shrubs. Yard waste comes from residential, commercial/retail, institutional, or industrial sources as part of maintaining yards or other private or public lands. Yard waste does not include two items: (A) Construction, renovation, and demolition wastes. (B) Clean lumber. |
