Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government, further to the Written Answers by Baroness Hayman of Ullock on 20 March (HL5459 and HL5460), whether assessments of samples for disposal at sea are determined by cost to the applicant or best available evidence.

Before material is disposed of at sea, Defra bodies follow OSPAR guidelines for assessing contaminant levels in samples. Cefas use the best available evidence when providing advice to the Marine Management Organisation (MMO) on contaminant levels in such samples. Assessments required may vary depending on the type of material and historic use of a site from which any material is dredged. Assessments are only used when the evidence they provide is necessary to determine if a material is suitable for disposal at sea, and this avoids disproportionate costs for applicants. The MMO then consider this evidence when determining applications to dispose of material at sea.
