If we cannot provide a final response within that time, because the request is complex and voluminous, we can extend the time limit for response up to 40 working days from receipt of the request.
Os na allwn roi ymateb terfynol o fewn y cyfnod hwnnw, oherwydd bod y cais yn gymhleth ac yn swmpus, gallwn ymestyn y terfyn amser ar gyfer ymatebion hyd at 40 diwrnod gwaith o dderbyn y cais.
