CHAPTER 330MUNICIPAL SOLID WASTE
SUBCHAPTER USTANDARD AIR PERMITS FOR MUNICIPAL SOLID WASTE LANDFILL FACILITIES AND TRANSFER STATIONS
RULE §330.983Definitions

The terms used in this subchapter have the following meanings, unless the context clearly indicates otherwise.

  (1) Bioremediation--The biological breakdown of waste occurring at a landfill prior to placing the waste in a landfill cell. Processing may include adding supplements and oxygen to speed the natural biological processes, after which the material will meet landfill acceptance standards and can be placed in a cell. Common sources of material requiring bioremediation are transportation or pipeline accidents and spills.

  (2) Category 1 municipal solid waste landfills--Landfills with a design capacity less than 2.5 million megagrams by mass or 2.5 million cubic meters by volume that operate in accordance with 40 Code of Federal Regulations Part 60, Subpart WWW, or Chapter 113, Subchapter D of this title (relating to Designated Facilities and Pollutants), as applicable.

  (3) Category 2 municipal solid waste landfills--Landfills with a design capacity greater than or equal to 2.5 million megagrams and 2.5 million cubic meters and a calculated uncontrolled non-methane organic compound emission rate less than 50 megagrams per year that operate in accordance with 40 Code of Federal Regulations Part 60, Subpart WWW or Chapter 113, Subchapter D of this title (relating to Designated Facilities and Pollutants), as applicable.

  (4) Category 3 municipal solid waste landfills--Landfills with a design capacity greater than or equal to 2.5 million megagrams and 2.5 million cubic meters and a calculated uncontrolled non-methane organic compound emission rate greater than or equal to 50 megagrams per year that operate in accordance with 40 Code of Federal Regulations Part 60, Subpart WWW, 40 Code of Federal Regulations Part 63, Subpart AAAA, or Chapter 113, Subchapter D of this title (relating to Designated Facilities and Pollutants), as applicable.

  (5) Construction--Any physical change or change in the method of operation (including fabrication, erection, installation, demolition, or modification of an emissions unit) that would result in a change in actual emissions.

  (6) Facility--A discrete or identifiable structure, device, item, equipment, or enclosure that constitutes or contains a stationary source, including appurtenances other than emission control equipment. A mine, quarry, well test, or road is not a facility.

  (7) Modification--As pertaining to a municipal solid waste landfill defined in 40 Code of Federal Regulations §60.751, means an increase in the permitted volume design capacity of the landfill by either horizontal or vertical expansion based on its permitted design capacity after May 30, 1991. Modification does not occur until the owner or operator commences construction on the horizontal or vertical expansion.

  (8) Modification of existing facility--Any physical change in, or change in the method of operation of, a facility in a manner that increases the amount of any air contaminant emitted by the facility into the atmosphere or that results in the emission of any air contaminant not previously emitted. The term does not include conditions listed in the definition of modification of existing facility under §116.10 of this title (relating to General Definitions).

  (9) Process--Any action, operation, or treatment embracing chemical, commercial, industrial, or manufacturing factors such as combustion units, kilns, stills, dryers, roasters, and equipment used in connection with them, and all other methods or forms of manufacturing or processing that may emit smoke, particulate matter, gaseous matter, or visible emissions.

  (10) Project--As pertaining to a municipal solid waste landfill defined in 40 Code of Federal Regulations §60.751, for the purposes of this subchapter means the construction or modification of a facility or a group of facilities submitted under the same registration.

  (11) Receptor--Any off-property recreational area, commercial/industrial structure, residence, or other normally occupied structures not used solely by the owner and/or operator of the municipal solid waste landfill site.

  (12) Site--All regulated units, facilities, equipment, structures, or sources at one street address or location that are owned or operated by the same person. Site includes any property identified in the permit or used in connection with the regulated activity at the same street address or location.

  (13) Source--A point of origin of air contaminants, whether privately or publicly owned or operated.

  (14) Waste solidification--The physical process used to reduce the mobility of constituents in a waste or to eliminate free liquids.

  (15) Waste stabilization--The chemical process used to stabilize the volatility of the constituents in a waste.
