01. Below Regulatory Concern (BRC) Facilities. A facility is BRC provided it is a processing facility that does not manage PCS or pumpable waste, and the cumulative volume of solid waste at the facility at any one (1) time is less than or equal to three hundred (300) cubic yards. (7-1-26) 02. Tier I Facilities. Tier I facilities must comply with the requirements identified in Section 011. A facility will be classified as a Tier I facility if the Department determines the facility is: (7-1-26) IDAHO ADMINISTRATIVE CODE IDAPA 58.01.06 Department of Environmental Quality Solid Waste Management Rules Section 009 Page 9 a. A landfill that only accepts, for disposal, materials that are not likely to produce leachate including, but not limited to, glass, plastic, cardboard, wood, composition roofing material, roofing paper, or ceramics, and which has a total disposal capacity of less than or equal to two thousand (2000) cubic yards; (7-1-26) b. A processing facility that only processes wastes including, but not limited to, untreated or unpainted wood, yard waste, sheet rock, clean paper products, animal manures, plant or crop residues, or garbage without meats or animal fats, and the cumulative volume of wastes at the facility at any one time is less than or equal to six hundred (600) cubic yards; (7-1-26) c. A processing facility that only manages PCS not excluded under Subsection 001.01.a.ix. or pumpable wastes and the cumulative volume of material at the facility at any one (1) time is less than or equal to two hundred (200) cubic yards; or (7-1-26) d. An emergency solid waste management facility that only accepts debris resulting from a natural disaster. (3-24-22) 03. Tier II Facility. Tier II facilities must comply with the Tier II general siting, operational and closure requirements and any applicable Tier II facility specific requirements. Tier II facilities are not required to install groundwater monitoring wells, leachate collection systems or liners. Facilities will be classified as a Tier II facility if the Department determines the facility is not: (1) landfilling or disposing of VSQG hazardous waste; (2) landfilling or disposing of materials with a high human pathogenic potential; (3) managing solid waste in a manner or volume that will form toxic leachate or gas; or (4) managing solid waste in a manner or volume that is likely to pose a substantial risk to human health or the environment. A Tier II facility is one that meets the four (4) above criteria and is identified below: (7-1-26) a. A NMSW landfill which has a total disposal capacity greater than two thousand (2000) cubic yards; (7-1-26) b. A processing facility or incinerator that has a cumulative volume of wastes at the facility at any one time that is greater than six hundred (600) cubic yards; (7-1-26) c. A processing facility that only manages PCS not excluded under Subsection 001.01.a.ix or pumpable wastes and the cumulative volume of material at the facility at any one (1) time is greater than two hundred (200) cubic yards; or (7-1-26) d. A transfer station or VSQG waste management facility. (3-24-22) 04. Tier III Facility. Tier III facilities must comply with the Tier III general siting, operating and closure requirements, groundwater monitoring requirements, install leachate collection systems, liners, air contaminant control systems and any applicable Tier III facility specific requirements. Facilities will be classified as a Tier III facility if the Department determines the facility is: (1) a facility landfilling or disposing of VSQG hazardous waste; (2) a facility landfilling or disposing of materials with a high human pathogenic potential; (3) a facility managing solid waste in a manner or volume that will form toxic leachate or gas; or (4) a facility managing solid waste in a manner or volume that is likely to pose a substantial risk to human health or the environment. (7-1-26) 05. Wood or Mill Yard Debris Facilities. All Wood and Mill Yard Debris Facilities that are not exempt from these rules as provided in Section 001.01 must be regulated as Tier I Facilities unless, based on site- specific criteria including but not limited to site geology, site soils, groundwater characteristics, distance to surface waters, and site climatic data, the Department determines the facility is more appropriately regulated under a different tier classification. Facilities not regulated as a Tier I Facility will be regulated as a Tier II Facility unless the Department determines the facility manages waste in a manner that will form toxic leachate or gas. (7-1-26) 06. Site Specific Classification. An owner or operator of a facility classified as a Tier I, Tier II or Tier III facility may request to be regulated pursuant to the requirements of a lower classification. An owner or operator requesting site specific classification must submit information demonstrating to the Department that, when in compliance with the requirements of a lower classification, the facility would not cause contamination, toxic leachate IDAHO ADMINISTRATIVE CODE IDAPA 58.01.06 Department of Environmental Quality Solid Waste Management Rules Section 010 Page 10 or gas, or concentrations of a substance that exceed standards in the IDAPA 58.01.01 “Rules for the Control of Air Pollution in Idaho.” The information included in any request under this subsection must include: (7-1-26) a. Characterization of waste and expected quantities of waste; (3-24-22) b. Site characterization including; (3-24-22) i. Site geology report; (3-24-22) ii. Site soils report; (3-24-22) iii. Groundwater report; (7-1-26) iv. Site climatic data; (3-24-22) c. Facility design plan; (7-1-26) d. Operating plan; and (7-1-26) e. Closure plan. (7-1-26) 07. General and Site Specific Classification Process. The Department's review of a request for a site specific classification will be conducted pursuant to the process set forth in Section 032. (7-1-26)
