The Board may promulgate rules under Article I of the Administrative Procedures Act¹ which establish a proper spacing of wells which, in its judgment, is necessary to an orderly withdrawal of water in relation to the allocation, by regular permits and temporary permits, of water to the land overlying the basin or subbasin. The Board shall conduct at least one public hearing at a location within or in close proximity to each major basin or subbasin before adopting rules establishing well spacing for such basin or subbasin.
