Maryland Code, Natural Resources § 8-1810

(a) If a local jurisdiction fails to notify the Commission that the local jurisdiction will develop a program, fails to submit a proposed program or changed proposal on time, or fails to obtain Commission approval of a proposed program or changed proposal that is submitted, the Commission shall prepare and adopt a program that satisfies the criteria adopted under § 8-1808 of this subtitle for the part of the Chesapeake Bay Critical Area or Atlantic Coastal Bays Critical Area in that local jurisdiction.

(b) Where a local jurisdiction failed to adopt or obtain Commission approval of a program, the Commission shall adopt a program for that jurisdiction by adopting regulations in accordance with Title 2, Subtitle 5 (Joint Committee on Administrative, Executive, and Legislative Review) and Title 10, Subtitle 1 (Administrative Procedure Act  1) of the State Government Article. Before the full Commission adopts a program under this subsection, the Commission shall appoint a panel of 3 of the Commission's members to conduct in the affected jurisdiction at least 2 public hearings at least 10 days apart on the proposed program, for which 2 weeks’ notice shall be published in a newspaper of general circulation in the local jurisdiction. A program adopted by the Commission under this subsection shall supersede any inconsistent local laws, ordinances, or plans.

(c) If the Commission adopts a program for a local jurisdiction, the program shall be implemented and enforced by local authorities in the same manner as if the program had been adopted by the local jurisdiction itself.

(d) If, at any time after the Commission has adopted a program for a local jurisdiction, the local jurisdiction submits an alternative program of its own that satisfies the criteria adopted under § 8-1808 of this subtitle and is approved by the Commission, the alternative program supersedes the program adopted by the Commission.
