Code 201. and shall comply with the control ' equipment requirements of this Section, except for new and'modified grain-handling operations which will handle an annual grain through-put of less than 300.000 bushels; provided, however, that for the purpose of this Subpart, an increase in the annual grain through-put. without physical alterations or additions to the grain-handling operation, shall not be considered a.modification unless such' Increase exceeds 3OX of the annual grain through-put' on which the operation's original construction and/or. operating permit was granted. If the grain-handling operation has been Operating lawfully without a permit. Its . annual grain through-put shall be determined as set forth' In the definition of the term "annual grain through-put." (Source: Amended at 3 Ml.
