(A) The department has jurisdiction over all natural shell deposits, including oysters, clams, and other mollusks occurring upon or within state-owned bottoms, and over all shell deposits lying above mean high water if those deposits have been created by the process of accretion to state-owned lands or bottoms.

(B) The department may grant permits to remove shell from these deposits for use in shellfish cultivation and mariculture. The permits must be granted for a term not to exceed three years and must specify conditions for removal. Permits may be granted only when no significant ecological perturbations are foreseen. If permitted removal does cause significant ecological perturbations as a result of the permittee failing to abide by conditions of the permit, the permittee must restore the area to its original condition or as close to its original condition as possible. The department must specify a fixed price for each unit of shell removed. Payments for shell removed must be made by the permittee on or before the tenth day of each month for the preceding month.
