Any person conducting clearing, grading, excavating, or filling activities at the time of adoption of this division may continue to operate pursuant to an existing grading permit or erosion and sediment control plan accepted by the division of engineering and need not obtain new permit coverage under section 16-102, 16-103, or 16-104 for such existing activities. Expansions of existing projects that prior to the expansion involve one (1) or more acres of land disturbance that are not covered by an approved erosion and sediment control plan shall require permit coverage under section 16-104. For existing projects with a total disturbance prior to the expansion of less than one (1) acre, expansions shall be authorized by revisions to existing erosion control plans, unless the expansion involves disturbance of more than one (1) acre of land.
