Oklahoma Administrative Code › Title 252 - Department of Environmental Quality › Chapter 100 - Water Quality Standards Implementation › Subchapter 24 - Particulate Matter Emissions From Grain, Feed or Seed Operations › Section 252:100-24-2 - Definitions

Current through Vol. 41, No. 20, July 1, 2024
The following words and terms when used in this subchapter,
				  shall have the following meaning, unless the context clearly indicates
				  otherwise:
"Enclosed Grain Handling Equipment"
means
				  equipment that is totally self-contained or is enclosed within a structure at a
				  grain, feed, or seed facility. Emissions from this equipment shall not be
				  exhausted to the atmosphere except through non-pressurized vents/openings, and
				  shall not be considered a source subject to emission calculations.
"Grain, Feed, or Seed Facility"
means the
				  contiguous or adjacent area under common control upon which a grain elevator,
				  feed mill, or grain and seed processing equipment or structures are located,
				  and all contiguous sites having common control.
"Grain, Feed, or Seed Operation"
means any
				  facility or installation at which grain, feed, or seed is loaded, handled,
				  cleaned, dried, stored, treated, or otherwise processed.
"Leg Capacity"
means the maximum process rate
				  for which the manufacturer designs the elevating portion of a grain, feed, or
				  seed facility on a per leg basis.
"Loading-out hours of operation"
means the hours
				  calculated by dividing the cumulative total quantity loaded out for a given
				  time period by 75% of the rated leg capacity. This quotient is equivalent hours
				  (not actual hours) of operation required to process the material loaded out.
				  Actual leg capacity may be adjusted to more or less than 75% by individual
				  facilities if documentation supporting the proposed adjustment is submitted to
				  and approved by the Division Director.
"Non-pressurized Vent or Opening"
means any vent
				  or opening which allows the emissions of air and/or contaminants at pressures
				  substantially equivalent to atmospheric pressure without the use of
				  mechanically-induced air flow.
"Pressurized Vent or Opening"
means any vent or
				  opening which allows the emissions of air and/or contaminants at pressures
				  greater than atmospheric pressure indicating the use of mechanically-induced
				  air flow.
"Receiving hours of operation"
means hours
				  calculated by dividing the cumulative total quantity received for a given time
				  period by 75% of the rated leg capacity. This quotient is equivalent hours (not
				  actual hours) of operation required to process the material received. Actual
				  leg capacity may be adjusted to more or less than 75% by individual facilities
				  if documentation supporting the proposed adjustment is submitted to and
				  approved by the Division Director.
"Total hours of operation"
means the sum of the
				  receiving hours of operation and the loading out hours of operation. Actual
				  hours may be less since receiving and loading-out operations may occur
				  simultaneously.
