Mining may not occur between March 1 and June 15. Excavations must be at least 25 feet from the ordinary water flow and the bank, may not go below the ordinary water level, and may not occur in vegetated areas or the riparian corridor. Excavated materials cannot be stockpiled below the ordinary high water level, and gravel washing and sorting must be conducted above the floodplain. Oversized material placed in the excavated area must approximate the original contours of the sand or gravel deposit, and no temporary stream crossings may be constructed for access. Petroleum and waste products cannot be stored in the watercourse.
Violators are guilty of a class C misdemeanor.
Excavations will not be permitted where the cumulative impacts of mining and other activities will degrade a waterway.
