(3) The authority must not require financial assurance of an amount greater than the total amount that the authority has reasonable grounds for believing is likely to be needed to remedy the foreseeable environmental harm that could result from the conduct of the authorised activity. (4) A financial assurance must be provided— (a) for the period specified in the authorisation; or (b) if no period is so specified, until— (i) the authorisation is varied to remove the condition requiring the financial assurance; or (ii) the authorisation is cancelled under section 55 or section 63 or is surrendered under section 66.
