38.This section requires SEPA to review and, where appropriate, update the flood risk assessment by 22nd December 2018, or by an earlier date specified by the Scottish Ministers, and then every 6 years thereafter. The 22nd December deadline and the requirement to review every 6 years come from Article 14 of the Directive.
