asked Her Majesty's Government:
On what date production of polychlorinated biphenyls (PCBs) ceased at the Monsanto site in Newport, Wales; and on what date and from which sites all production of PCBs by any manufacturer ceased in the United Kingdom. [HL3220]
I understand that the production of PCBs ceased in 1977 at the Monsanto, Newport site, and that all UK production ceased in that same year.
asked Her Majesty's Government:
Where and how all hazardous wastes from the Monsanto site in Newport, Wales, were disposed of following the closure of the Maendy and Brofiscin quarries in 1972. [HL3222]
