(a) Review by governing body.--The governing body shall review any area created under section 8¹ seven years after the date of its creation and every seven years thereafter. In conducting such review, the governing body shall ask for the recommendations of the planning commission, the county planning commission and the advisory committee, and shall, at least 120 days prior to the end of the seventh year and not more than 180 days prior to such date, hold a public hearing at a place within the area or otherwise readily accessible to the area. Prior to the commencement of such review, notice thereof shall be given by publication in a newspaper having a general circulation within the area, by notice posted in five conspicuous places within, adjacent to or near the area and by notice, in writing, to all persons owning land within the area that the agricultural security area will be reviewed in accordance with law. All such notices shall be given 30 days before the commencement of such review. Persons wishing to modify the area shall submit proposed modifications within 30 days of the date of such notices. Thereafter, in conducting such review the governing bodies shall follow all the procedures and requirements of sections 5, 6, 7 and 8² for the consideration of the agricultural security area and proposed modifications thereto. Within ten days of its action of termination or modification, the governing body shall file a notice of termination or modification with the recorder of deeds, who shall record such notice in such manner and place as has been provided in the original recording of the agricultural security area. The governing body shall also file a notice of termination or modification with the planning commissions of the county and of the local government unit. If the governing body does not act, or if a modification of an area is rejected, the area shall be deemed to be readopted without modification for another seven years.

(b) Interim review.--If, within the seven-year period, 10% of the land within the agricultural security area is diverted to residential or nonagricultural commercial development, the governing body may review the diversion and may request, in writing, that the local and county planning commissions and the agricultural security area advisory committee study its review and make recommendations within 30 days of the written request. The governing body shall thereupon conduct a public hearing, after providing the same notice as that which is required under section 6(c). The hearing shall be held no sooner than 45 days after the governing body has submitted written requests for review and recommendation to the planning commissions and advisory committee. The governing body then may terminate or modify the agricultural security area.
