Trafododd y Grŵp nifer o faterion amgylcheddol cysylltiedig oedd o ddiddordeb i Aber Hafren.  Cytunwyd y dylid rhoi blaenoriaeth i ystyried y materion hyn, am eu bod yn faterion brys a hefyd am eu perthnasedd posib i gylch gwaith y Grŵp o ran Hinkley Point C.
The Group discussed a number of related environmental matters of interest within the Severn Estuary.  It was agreed that consideration of these would need to be prioritised both from the perspective of their immediacy and their potential relevance to the Group’s remit as it relates to Hinkley Point C.
