Are exemptions available from the "hazmat" notification requirements of the VTM Regulations?

Under Regulation 4 of the VTM Regulations the MCA may exempt the owner, agent and master of a specified ship on a scheduled service from the "hazmat" notification requirements in relation to a voyage that is scheduled to last up to 12 hours and is part of a scheduled service between ports within the UK. Exemptions are only effective if in writing and are subject to conditions.
