The Secretary may (for such period, or indefinitely, as the Secretary deems necessary to effectuate the purposes of this chapter) refuse to provide official inspection or the services related to weighing otherwise available under this chapter with respect to any grain offered for such services, or owned, wholly or in part, by any person if the Secretary determines (1) that the individual (or in case such person is a partnership, any general partner; or in case such person is a corporation, any officer, director, or holder or owner of more than 10 per centum of the voting stock; or in case such person is an unincorporated association or other business entity, any officer or director thereof; or in case of any such business entity, any individual who is otherwise responsibly connected with the business) has knowingly committed any violation of section 87b of this title, or has been convicted of any violation of other Federal law with respect to the handling, weighing, or official inspection of grain, or that official inspection or the services related to weighing have been refused for any of the above-specified causes (for a period which has not expired) to such person, or any other person conducting a business with which the former was, at the time such cause existed, or is responsibly connected; and (2) that providing such service with respect to such grain would be inimical to the integrity of the service.
