SECTION 252:100-24-2. Definitions

  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.
