A. 
General procedure. Prior to the start of any land development or construction within the unincorporated area of Allegany County, including subdivision, building construction, grading, clearing, filling or other earth or contour change, including surface mining, gob pile removal and borrow pits, an individual, firm, corporation, agency or other entity must first make application to the Allegany County Planning and Zoning Commission for a land use permit (grading permit). This permit must be in conformance with Part 4, Zoning, and Part 1, Subdivision Regulations, of this chapter.
B. 
Surface mining projects will be regulated and monitored by the State Bureau of Mines and/or the Water Resources Administration following the approval of the Soil Conservation District and the other reviewing agencies and the issuance of the County land use permit.
A. 
The following activities are exempt from the provisions of this Part 2:
(1) 
Clearing or grading activities that are subject exclusively to state approval and enforcement under state law and regulation.
[Amended 6-10-1992]
(2) 
Agricultural land management practices as defined in § 360-27.
