North Dakota Administrative Code › Title 33.1 - Department of Environmental Quality › Article 33.1-24 - Hazardous Waste Management › Chapter 33.1-24-02 - IDENTIFICATION AND LISTING OF HAZARDOUS WASTE › Section 33.1-24-02-171 - Definitions

Current through Supplement No. 393, July, 2024
As used in sections
				  33.1-24-02-170 through
				  33.1-24-02-179, all terms not
				  defined in this section have the meaning given them in North Dakota Century
				  Code chapter 23.1-04 and 33.1-24-01 through 33.1-24-05 and section
				  33.1-24-05-401.
1. "Equipment" means each valve, pump,
				compressor, pressure relief device, sampling connection system, open-ended
				valve or line, or flange or other connector, and any control devices or systems
				required by sections
				33.1-24-02-170 through
				33.1-24-02-179.
2. "Hazardous secondary material management
				unit shutdown" means a work practice or operational procedure that stops
				operation of a hazardous secondary material management unit or part of a
				hazardous secondary material management unit. An unscheduled work practice or
				operational procedure that stops operation of a hazardous secondary material
				management unit or part of a hazardous secondary material management unit for
				less than twenty-four hours is not a hazardous secondary material management
				unit shutdown. The use of spare equipment and technically feasible bypassing of
				equipment without stopping operation are not hazardous secondary material
				management unit shutdowns.
3. "In
				gas or vapor service" means that the piece of equipment contains or contacts a
				hazardous secondary material stream that is in the gaseous state at operating
				conditions.
4. "In light liquid
				service" means that the piece of equipment contains or contacts a material
				stream where the vapor pressure of one or more of the organic components in the
				stream is greater than three-tenths kilopascals at twenty degrees Celsius, the
				total concentration of the pure organic components having a vapor pressure
				greater than three-tenths kilopascals at twenty degrees Celsius is equal to or
				greater than twenty percent by weight, and the fluid is a liquid at operating
				conditions.
5. "Malfunction" means
				any sudden failure of a control device or a hazardous secondary material
				management unit or failure of a hazardous secondary material management unit to
				operate in a normal or usual manner, so that organic emissions are
				increased.
6. "Open-ended valve or
				line" means any valve, except pressure relief valves, having one side of the
				valve seat in contact with hazardous secondary material and one side open to
				the atmosphere, either directly or through open piping.
7. "Process vent" means any open-ended pipe
				or stack that is vented to the atmosphere either directly, through a
				vacuum-producing system, or through a tank (for example, distillate receiver,
				condenser, bottoms receiver, surge control tank, separator tank, or hot well)
				associated with hazardous secondary material distillation, fractionation,
				thin-film evaporation, solvent extraction, or air or steam stripping
				operations.
8. "Sampling connection
				system" means an assembly of equipment within a process or material management
				unit used during periods of representative operation to take samples of the
				process or material fluid. Equipment used to take nonroutine grab samples is
				not considered a sampling connection system.
9. "Startup" means the setting in operation
				of a hazardous secondary material management unit or control device for any
				purpose.
