After such hearing and finding, the Commissioner of Agriculture may issue against such dealer or store a directive to cease and desist, and prescribe such corrective terms and conditions as he determines upon the hearing evidence to be in the public interest. Such corrective terms and conditions may include one or more of the following or parts thereof, and other reasonable and similar terms or conditions with like corrective purpose, subject to such regulations as the commissioner prescribes in aid of the effectiveness of such directive: (1) In cases in which prices are favoring, special or discriminatory, directing the revision of prices at which milk is so sold; or directing and specifying restoration of nondiscriminatory prices; or directing that no further sales be made to favored purchasers for a period not exceeding ninety days. Such provision may prohibit the sale or offer of reasonably similar quantities and qualities of milk under similar conditions to different purchasers at unreasonably different prices; or the sale or offer of milk of special properties or quality, or with an uncustomary amount of service or in an unusual container at prices which do not make allowance for differences in cost existing between such sales or offers and usual sales; (2) directing the revision of prices at which milk is sold; or directing and specifying restoration of normally prevailing resale prices for a period not exceeding ninety days considering comparable milk in the same locality at any reasonable preceding period of time in which resale price conditions were sufficiently stable to protect producers’ prices, adjusting for any difference in producers’ prices at such time and place; (3) prohibiting any dealer or store, directly or indirectly, from furnishing or receiving or offering to furnish or receive in connection with a sale or purchase of milk or offer to sell or purchase milk any rebate, discount, premium, gift or other thing of value, an unreasonable service or extension of credit, or an advertising allowance; from charging a combined price for milk, together with another commodity, or a service which is less, or is represented to be less, than the aggregate of the price of the milk and the price or value of such commodity or service when sold or offered for sale separately; or from otherwise applying or attempting to apply any method or device intended to defeat the policy of this part, or to defeat or evade any provision of this part or of any order, ruling or regulation issued hereunder. Nothing in this section shall be construed to prevent a dealer from participating in any program sponsored or conducted by the commissioner or any other governmental authority, designed to make milk available at specially low prices to groups designated by appropriate public authorities for the purpose of increasing consumption. Hearings may be held and directions issued under this section affecting one or more dealers concurrently or independently; and may be held only on such notice as the emergency reasonably permits. Directions under this section may be served upon a dealer at his place of business or by registered or certified mail to his last-known address.
