A local jurisdiction that adopts a local amendment to the Standards shall ensure that the local amendment is adopted in accordance with applicable local law. To keep the database established under this subtitle current, a local jurisdiction that adopts a local amendment to the Standards shall provide a copy of the local amendment to the Department: at least 15 days before the effective date of the amendment; or within 5 days after the adoption of an emergency local amendment.
