Upon receipt of a report and recommendations based upon an investigation conducted under § 90.15, the Secretary shall make a determination that the applicant meets the qualifications for receiving grain.

Before receiving delivery of such grain the applicant shall execute and deliver to any officer authorized to enforce this part written assurances as follows:

(a) That grain made available to him under this part will be used exclusively for the prevention and abatement of crop damage by migratory waterfowl and that no portion of such grain will be sold, donated, exchanged, or used as feed for livestock or other domestic animals or for any other purpose;

(b) That consent is granted to any officer authorized to enforce this part, to inspect, supervise or direct the placement and distribution of grain made available under this part for the prevention of crop damage at all reasonable times;

(c) That free and unrestricted access over the premises on which feeding operations have been or are to be conducted shall be permitted at all reasonable times, by any officer authorized to enforce this part and that such information as may be required by the officer will be promptly furnished; and

(d) That the applicant will not take, nor permit his agents, employees, invitees, or other persons under his control to take migratory game birds on or over any lands or waters subject to his control, during the time such grain is placed, exposed, deposited, distributed, scattered, or present upon such lands or waters, nor for a period of 10 days immediately following the consumption or removal of such grain from such lands or waters.
