Quick Screen

To determine whether your facility qualifies for this standard permit, first consider this quick screen:

  • A feedmill does not qualify for this standard permit if it has on-site permanent raw grain storage capacity of more than 2.5 million bushels.
  • A feedmill does not qualify for this standard permit if any associated fuel-fired equipment (including, but not limited to, boilers, dryers, and burners) has an individual heating rate of ten million British thermal units per hour (Btu/hr) or greater, or a combined heating rate of greater than 20 million Btu/hr. This requirement does not apply to engines.
  • A feedmill, portable auger, or hay grinder does not qualify for authorization under this standard permit if any individual engine (or combination of engines) rated greater than 525 horsepower is used.
  • The feedmill, portable auger, or hay grinder must not be a new major stationary source or major modification as defined by Title 30 Texas Administrative Code (30 TAC) Section 116.12, Nonattainment and Prevention of Significant Deterioration Review Definitions.
  • The feedmill, portable auger, or hay grinder must not be located at a major stationary source.

If the feedmill, portable auger, or hay grinder cannot meet the conditions of this standard permit, you may qualify for other permitting options. To review your options, see Types of New Source Review Authorizations.
