Such determination and the basis therefor shall be in writing. The Commissioner may specify the application and the duration of its effectiveness. In cases of reasonable doubt, competition should be solicited. Any request by a purchasing agency that a procurement be restricted to one potential contractor shall be accompanied by an explanation as to why no other will be suitable or acceptable to meet the need.
