"We've got to have a surety that this tip is going to be seen to, and not only this tip but other tips for other people that could be in the same situation that we are, especially with the rain we're having at the moment.".
There are 2,573 disused coal tips in Wales, according to Welsh government data - the vast majority of which are in the former coal mining communities of the South Wales Valleys.
Ms Morgan said she believes lessons have not been learned from the Aberfan disaster in 1966 when a colliery spoil tip collapsed killing 144 people, including 116 children.
Meanwhile, the Welsh government has outlined proposals for a Disused Tips Authority for Wales, which would take on responsibility for coal tip safety in future.
He said that if a larger tip would have come down, his street "would have gone" and the tips needed to be taken "down to a safe level".
