Hinkley Point C: Opposing views over mud toxicity claims
Claims 300,000 tonnes of mud due to be dumped off Cardiff Bay is toxic are "wrong, alarmist and go against all internationally-accepted scientific evidence".
Controversial plans to dispose of mud from EDF's £19.6bn Hinkley Point C nuclear project are being scrutinised by members of the Welsh assembly.
Campaigners want further testing, but the company behind the project said the mud had been tested "independently to highly conservative standards".
Chris Fayers, EDF's head of environment, and Tim Deere-Jones, a marine pollution consultant who has spearheaded the campaign against the dumping, both gave evidence to AMs on the petitions committee.
