NR 660.10(60)(L)(L) Halogen acid furnaces (HAFs) for the production of acid from halogenated hazardous waste generated by chemical production facilities where the furnace is located on the site of a chemical production facility, the acid product has a halogen acid content of at least 3%, the acid product is used in a manufacturing process, and, except for hazardous waste burned as fuel, hazardous waste fed to the furnace has a minimum halogen content of 20% as-generated.

NR 660.10(60)(m)(m) Such other devices as the department may, after notice and comment, add to this list on the basis of one or more of the following factors:

NR 660.10(60)(m)1.1. The design and use of the device primarily to accomplish recovery of material products.

NR 660.10(60)(m)2.2. The use of the device to burn or reduce raw materials to make a material product.

NR 660.10(60)(m)3.3. The use of the device to burn or reduce secondary materials as effective substitutes for raw materials, in processes using raw materials as principal feedstocks.

NR 660.10(60)(m)4.4. The use of the device to burn or reduce secondary materials as ingredients in an industrial process to make a material product.

NR 660.10(60)(m)5.5. The use of the device in common industrial practice to produce a material product.

NR 660.10(61)(61) “Infrared incinerator” means any enclosed device that uses electric powered resistance heaters as a source of radiant heat followed by an afterburner using controlled flame combustion and which is not listed as an industrial furnace.

NR 660.10(62)(62) “Inground tank” means a device meeting the definition of “tank” in this section whereby a portion of the tank wall is situated to any degree within the ground, thereby preventing visual inspection of that external surface area of the tank that is in the ground.

NR 660.10(63)(63) “Injection well” means a well into which fluids are injected.

NR 660.10(64)(64) “Inner liner” means a continuous layer of material placed inside a tank or container which protects the construction materials of the tank or container from the contained waste or reagents used to treat the waste.

NR 660.10(65)(65) “Installation inspector” means a person who, by reason of that person’s knowledge of the physical sciences and the principles of engineering, acquired by a professional education and related practical experience, is qualified to supervise the installation of tank systems.

NR 660.10(65m)(65m) “Intermediate facility” means a facility that stores hazardous secondary material for more than 10 days, other than a hazardous secondary material generator or reclaimer of such material.

NR 660.10(66)(66) “International shipment” means the transportation of hazardous waste into or out of the jurisdiction of the United States.

NR 660.10(67)(67) “Lamp”, also referred to as “universal waste lamp,” is defined as the bulb or tube portion of an electric lighting device. A lamp is specifically designed to produce radiant energy, most often in the ultraviolet, visible and infra-red regions of the electromagnetic spectrum. Examples of common universal waste electric lamps include, but are not limited to, fluorescent, high intensity discharge, neon, mercury vapor, high pressure sodium and metal halide lamps.

NR 660.10(67m)(67m) “Land-based unit” means an area where hazardous secondary material are placed in or on the land before recycling. This definition does not include land-based production units.
